Dispersing and mixing device

[Detailed Description of the Invention]

The present invention relates to the distributed mixture device which formed the pouring mouth of pouring fluid in the pipe wall of the lead pipe for passing main fluid, Specialf: Quantity viscosity main fluid (distributed mixture device for using, when the character of volume, viscosity, and other fluid changes on the occasion of the device of the method zeta 2 Horny sake which receives two and mixes gas-like fluid, such as steam, or mixture (related two.)) As the method of pouring the fluid of a different kind from this into main fluid, and mixing, For example, the pipe which equipped the inflow mouth side of a line mixer with pouring oral regions, such as a pipe which has a T-tube, a 1-character pipe with a nozzle, or a multi-pouring mouth, is made to connect, and the method of mixing by the line mixer of succession to the synthetic style produced by pouring in the fluid of a kind which is different from this in main fluid from a pouring mouth is known. However, when the physical properties of main fluid and pouring fluid differ remarkably, for example steam is mixed to main fluid, such as a fluid and a solid content fluid, 0 which has the problem that homogeneous mixing fluid is not obtained efficiently according to the conventional describing [ above ] method when mixing steam directly and heating the starch milk in which viscosity becomes very high, if a To rise case mixes a chemical change, for example as a result of mixing -- for example Generally as a device which mixes steam with the main fluid of a fluid, it is tapered shape (: Venturi part whom a section expands toward the lower stream is formed in the lead pipe of main fluid, and what allocates many pouring nozzles in the Venturi's pipe wall part extremely, and pours high-pressure steam into it is used.). However, since Pressure drop is excessive, it is difficult, and it is change (it receives two, and the mixed use range is narrow, homogeneous-mixing nature is insufficient, and there are problems, such as the necessity of drilling many pouring mouths in noise oscillating generating and Venturi part.) of a flow to agitate the main fluid of high viscosity in this method. When pouring steam especially into starch dispersion liquid and manufacturing paste, it is change with remarkable viscosity (; there was a fault that are easy to produce the so-called generation of unmixed-in lump of flour and the blockade of a pouring mouth since the mixture to depend is poor, and mixing became insufficient by rapid increase of viscosity, and Pressure drop also became large.). the present invention -- the fault of these conventional methods -- it is going to cancel -- it is a thing. Namely, distributed mixture device C of the form of the thing mentioned above by the present-invention beginning: It set, the spiral element twisted focusing on the tube axis was allocated in the lead pipe, the pouring mouth was arranged on the peripheral part pipe wall of the spiral element, and the static mixer was allotted to the downstream part. The present invention is formed in the tapered shape to which a section radius expands the lead pipe, and the distributed mixture device which allocated the spiral element which makes the internal; Nitaver-like perimeter is provided. The present invention is explained in full detail based on a desirable embodiment below. In Drawing 1, one example barrel distribution mixture device 10 of the present invention comprises fundamentally injection part 2 and static mixer 1 part which follows, Drawing portion 1*2 uses lead pipe 11 as a main part, pouring mouth 3 is carrying out two or more openings to the pipe wall of injection part 2, and spiral element 4 is fitted in in lead pipe 11 of injection part 2. Static mixer 1 part is publicly known in itself. for example, it twists about 180 degrees -- it fits in mutual f2 and is formed so that it twists, and the end may carry out the Is rectangular cross of the shuttlecock 12, and it may twist mutually and a direction may be reversed (for example, thing given in JP,44-8290,B, JP,52-17264,B, etc.). spiral Encmentment 4 of injection part 2 inside twists A of one sheet focusing on a tube axis -- at least 360 degrees or more -- it twists, has an angle and is usually 360~720 degrees. Although a practical maximum is about 3600 degrees, this twists, is a To obey thing and is not necessarily limited to the practical design of an injection part on manufacture of a board by this maximum Twist angle. The pipe wall of lead pipe 11 of injection part 2 (= is allotted so that pouring mouth 3 may be distributed to at least 2 or more and each [ in lead pipe 11 usually divided by the integer multiple of 2, and spiral element 4 ] pipe room at least one or more.) The number and distribution of actual injection part 2 are chosen according to the object, and are allotted with the interval of the direction of the circumference of a pipe wall, and the direction of an axis, or a suitable Helen rotation angle degree interval. Lead pipe 11C of pouring mouth 3: The receiving mounting angle is direction (: it axis C= receives and it is preferred to carry out a predetermined angle inclination.) of the flow of main fluid as it illustrates to Drawing 1 in an axial cross section. lead pipe 11 (direction C:pipe wall Tangent I: the mounting angle which receives two has an angle which intersects perpendicularly with a pipe wall (radial direction) -- being sufficient (on the ease of attachment, and an effect) -- spiral element 4 twists -- it receives, and predetermined angle diagonal crossing can be carried out and it can also pour in.) of pouring mouth [ in / to an axis / a rectangular section ] 3 Since revolution Know \ distribution mixture of the pouring fluid 5 from pouring mouth 3 is carried out by the Helen revolution style operation of spiral element 4 in the present invention, the pouring angle of pouring mouth 3 in an axial rectangular cross section is permitted as long as it is an angle which is not contrary to direction of the Helen revolution style formed. The caliber of pouring mouth 3 and a number are defined according to the flow of pouring fluid 5 which should be mixed, and generally, although it is more preferred than the flow velocity of main fluid 6 that it is a real upper flame as for the pouring speed of pouring fluid 5, according to the necessity for mixture, it is chosen suitably. Although pouring lead pipe 13 of pouring fluid 5 which results in pouring mouth 3 is formed according to arrangement of pouring mouth 3, From the ease on easy fence manufacture of composition, it is like 1st [ The ] figure illustration as an example of -, As for O pouring mouth 3 in which it supposes that it is direct tubular, pouring mouth 3 will be branched from now on, and the end of pouring lead pipe 13 screws plug 8 on, it is preferred to form extension 3a prolonged in the direction opposite to pouring mouth 3 from a turning point with the pouring lead pipe 13, The tip is screwed on by plug 8, and makes easy cleaning of pouring mouth 3 for the time of the blockade of pouring mouth 3, and its prevention. lead pipe 11 has been a thing of the usually same caliber as injection part 2 and static mixer 1 part enough -- the thing of the completion as a static mixer part -- business -- as for O To case, it is combined by a flange, screwing, etc. according to the mechanism with Deposition. Preferably, the beginning of succession of static mixer 1 part twists, and it supposes that shuttlecock ?2a is contrary to the direction which spiral element 4 of injection part 2 twists, twists with end 4a of spiral element 4 still more preferably, and makes the end of shuttlecock 12a cross. Two or more pouring mouths are provided, and, of course, Lycium chinense grows without using some of them at the time of actual use. The pouring fluid which differs in a kind can also be mutually poured in from two or more pouring mouths. In the above example, although injection part 2 is constituted by lead pipe 11 of the uniform caliber, it forms injection part 2a as tapered shape lead pipe 9 which a section radius expands as it is shown in Drawing 2, it fits into the inside spiral Niremen 4b which makes the tapered shape perimeter, and constitutes injection part 2'a. Other conditions may be the same as the 1st example and outline. According to this composition, it is useful to mixture (it contains, when accompanied by a reaction) of the fluid that a sudden quality change is produced by inflow mixture of pouring fluid 5, and viscosity goes abruptly up. That is, in Up\ of the caliber of the inflow mouth of usual main fluid 6, excessive Pressure drop arises by the rise of viscosity, large pump pressure must be taken, and the capacity to resist pressure of a device is also thick (the problem which must be carried out is mitigable.). This example is a case so that steam may be poured into this for the above-mentioned starch milk (suspension) as main fluid and a thickening agent may be manufactured. In this case, steam (although mixture of steam was not uniform <=; performed enough in the conventional mixing method although starch steamed as a result of heating depended two and it became a hyperviscous thickening agent, but cotton powder arose locally in many cases, it is a device (= if it depends, a uniform thickening agent will be obtained.) of the present invention) Although spiral Niremen 4 and 4b as stated above is carrying out revolution mixture of the fluid as the fundamental role, it is the point currently twisted especially in the same direction, and differs from the conventional static mixer (it twists from a point of mixed efficiency, and a shuttlecock reverses the direction twisted C2 the whole sheet, and is assembled). When the direction which twists and twists a shuttlecock by turns is reversed, the pouring dispersion effect accompanying the compulsive revolution power and this by the flow velocity of pouring fluid 5 (steam etc.) is checked. Although a short thing is constituted from the ease on manufacture by one, it divides suitably, manufactures and spiral elements 4 and 4b of the present invention are assembled, when huge. Continuing the conventional Twist shuttlecock for static mixers in the same direction to twist, naturally combination or assembling and considering it as spiral element 4 belong to the present invention. Although the danger which spiral element 4 of the present invention twists is twisted once and it is expressed with Specific axis of direction length of axis l and diameter d of 180 degrees, the desirable range differs between l/which it is desirable and twists for [ conventional ] static mixers and by which l/d = 0.7~1 is made general to a shuttlecock, and 3 = 1~3. It is because the object is to make a sudden revolution style produce. In the present invention, the number of pouring mouths can essentially decrease as compared with the conventional method for the powerful revolution mixture effect by a spiral element (it is that [ Special (as compared with Yuventite type thing, it drops to 1/tens) ], manufacture is very easy, and check of a pouring mouth (nozzle) and cleaning are also easy (it can do two.)). Above, according to the present invention as a detailed explanation, mixture of high viscosity fluid is performed uniformly, the distributed mixture between the fluid in which viscosity goes abruptly up especially by mixture becomes easy, the composition as a device is simplified, and manufacture, operation, and maintenance cost are reduced by Pressure drop of mixed operation, and reduction. According to the distributed agitating equipment of the present invention, the length of the device for comparing with what connected the conventional injection part which only equipped the lead pipe with pouring mouth branching and publicly known static mixer, and obtaining the same degree of mixing can be shortened. In the present invention, already quite sufficient mixture is performed also in an injection part, and it is from a vine. Hereinafter, a detailed description of the invention is carried out according to an operation example. Example 1 Heating by the steam of the starch paste of normal temperature was performed on the following conditions using the device shown in Drawing 1 of heating by the steam of fluid. Since uniform distribution of the steam was carried out by an injection part as compared with the case where the device which does not have an injection part C varnish pie r * Le-like element performs similarly, while generating of the noise vibration accompanying condensation of steam decreased much more, the fluid of a more uniform temperature was obtained. Heating conditions: 81kVhr pouring of the steam (pressure 10kVcdG) was carried out by using starch paste cold liquid 11201A1r (30degreeC, specific gravity 1.2 * viscosity 300cp) as main fluid. Temperature 70±3degreeC, viscosity 80~]00cp, and the device passage pressure loss of generation fluid were beyond 0 and 5. axis. Example 2 Starch cooker A device of the form of the illustration to Drawing 2 (diameter of taper people Rollo 22fl, diameter of taper appearance Rollo 52.7ff) 450 spiral element Twist angles and a taper part (injection part) -- length 23 (1 m) twist a static mixer 180 degrees, and by turns, in the reversal Twist direction, it makes an end intersect perpendicularly and the caliber of 2 inches (5011F) arranges four shuttlecocks -- xi specific gravity -- having carried out -- it thickening-agent-ized by heating mixture by the steam of the starch milk containing starch 24 target. starch milk -- pressure 2.5 kVIc so -- a pump -- Flow[-- coming out 11000 imitation and feeding -- saturation steam -- pressure 3'fdG from a pouring mouth (nozzle diameter 1 / 8 inches (30 phi) x five pieces). It poured in by flow 124 kVhr and obtained the starch thickening agent (90degreeC). Pressure a thickening agent is uniform, and cotton powder is not contained, but according to steam heating -- the disadvantage rise came out only and there was (it is less than [ plus 1.5 kg/;-4 ] at pump exit pressure). Generating of noise vibration was slight. Comparative example Drawing 4 (- shown publicly known venturi type-type device (entrance caliber of 1112 inches (3811m1))) It acts as Venturi, pump feeding of the starch milk of Example 2 and the opportunity is carried out by 5001/hr using phix300 Rice part caliber 20'1lll, diameter IW inch of appearance Rollo (38 A claim), and nozzle 2ff, and it is [ Example 2 and ] the same (pouring mixture was carried out and the varnish team was thickening-agent-ized.). Loud noise 70~90 With (dB) generating, pump pressure went abruptly up, and amounted to 5 at 'l/dG, and the amount of feeding fell to 50'At. The generated thickening agent (as for;, most quantity of cotton powder was contained, and the equalization was impossible.)
