Abstract
The utility model discloses a wall-scraping type high effective heat exchanger which is a heating and cooling device for high-viscosity materials. A plurality of hollow inner cylinders are concentrically installed in a hollow outer cylinder, and rotary wall-scraping stirring mechanisms which are concentric are arranged among the inner cylinders, the outer cylinder, and among each inner cylinder. Circular walls are clung by the wall-scraping panels which are positioned on the inner and outer sides of the wall-scraping stirring mechanisms. On one hand, the materials in each cylinder are stirred. Meanwhile, adhering substances on each cylinder wall are scraped off continuously to enhanced heat transfer. The quantities of the inner cylinders can be increased or decreased by the utility model according to heat transfer load. The utility model has the advantages of larger heat transfer area of unit volume, high heat-transfer efficiency, one wide flow passage of the high-viscosity materials, short flow paths, and less loss, and is suitable for using as the heat exchanger or one reactor of the high-viscosity and high-exothermicity materials.
Description
The utility model belongs to the heating and cooling device of high sticking material.
The heating and the cooling of high sticking material are the problems of fine solution of always failing in the industrial process.Because the heat transfer that the high viscosity of fluid makes material is difficulty, the particularly polymerisation in solution and the bulk polymerisation process of polymer monomer in the polymer chemistry industry quite, as ethene, butadiene, styrene etc.Along with the raising of reaction conversion ratio, the polymer molecular weight increase increases material viscosity greatly in production processes of polyalcohol, discharges a large amount of reaction heat simultaneously.High viscosity and high exothermicity have a strong impact on the stability of course of reaction, influence the CONCENTRATION DISTRIBUTION and the Temperature Distribution of material in the reactor, cause polymeric articles with low quality, even make the polymerization process failure.
The common method that the high adhesive aggregation of present solution closes the heat dissipation problem of process has: one, adopt plate type heat exchanger, this heat exchanger heat exchange efficiency is higher, is suitable for the heat exchange of viscous fluid.But along with the increase of sticking wall thing, heat exchange efficiency sharply descends, and increase falls in pressure.Exist the defective of sticking wall thing cleaning difficulty simultaneously.Two, adopt votator to scrape the wall type heat exchanger, this heat exchanger is that the cylinder of having settled a band to scrape wallboard at the outer cylinder center of hollow is formed, and it is scraped wallboard and is close to cylinder inner wall, during work, pass to heating or cooling medium outside in the cylinder cavity, pass to material in the cylinder, external force drives scrapes the wallboard rotation, stirs material on the one hand, clear up the sticking wall thing of wall on the one hand, though this heat exchanger has solved clear wall problem, the heat exchange area of unit volume is less, so heat exchange efficiency is low.
In view of above-mentioned, the purpose of this utility model aims to provide a kind of heat exchange efficiency height, and the pressure drop loss is little, and that stirs that clear wall does to make good use of scrapes the wall type heat exchanger, makes concentration, the uniformity of temperature profile of material, to improve the quality of polymeric articles.
Technical solution of the present utility model is to adopt the multiple wall rabbling mechanism of scraping.It is the inner cylinder (n=1 that n hollow is installed in the outer cylinder of hollow with one heart, 2,3 ... positive integer), between outer cylinder and inner cylinder, all be equipped with between each inner cylinder and the inner cylinder and scrape the wall rabbling mechanism, it is concentric with outer cylinder to scrape the wall rabbling mechanism, drives rotation by external force, and it is scraped wallboard and is close to the cylinder outer wall wall that is positioned at its outer cylinder inner wall and is positioned at it.During work, between each cylinder, feed pending material, in the cavity of inside and outside cylinder, feed heating or cooling medium,, scrape the rotation of wall rabbling mechanism by corresponding heating of wall or cooling material, stir material by scraping wallboard, make mixing of materials even on the one hand, temperature, CONCENTRATION DISTRIBUTION homogeneous, the while constantly scrapes off the sticking wall thing of each cylinder wall, upgrade heating surface, strengthening heat transfer.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model structural profile schematic diagram;
Fig. 2 is the A-A section of Fig. 1.
With reference to Fig. 1, the inner cylinder 2 of two hollows has been installed in the outer cylinder 1 of hollow with one heart, between outer cylinder and inner cylinder, all be equipped with between inner cylinder and inner cylinder and scrape wall rabbling mechanism 3, in the diagram concrete structure, the wallboard 4 scraped of scraping the wall rabbling mechanism and be segmentation vertically connects to form with ralocatable mode, perhaps also available hinge type or spring are formed by connecting, preferably making each section scrape wallboard is staggered, be alternately to be close to the inwall of outer cylinder and the outer wall of inner cylinder respectively, the multiple wall mechanism of scraping adopts single rotation that drives.Conduct heat for further strengthening the cylinder wall, also the spiral plate washer can be set in inside and outside cylinder cavity.
The utility model adopts the multiple wall mechanism of scraping, can increase and decrease the inner cylinder number according to the heat transfer burden requirement, improve the heat transfer area of unit volume, because of the floating type wallboard of scraping can be close to automatically and scrape wall, in whipping process, bring in constant renewal in the heating surface of process side, exchange capability of heat is multiplied, improved heat transfer efficiency effectively, the multiple wall rabbling mechanism of scraping can make material well mix simultaneously, concentration, uniformity of temperature profile, the heat exchanger of this structure, high sticking material runner is wide, flow process short, the pressure drop loss is little, and can prevent the deposition and the material bonding of solid particle.
The wall heat exchanger of scraping that the utility model provides can be used for high cooling or heat treated of gluing material, also can be used to handle the reaction unit that contains the solid particle viscous material or directly be used as similar system, also can be used as high viscosity, the outer circulation cooling or the firing equipment of the reactor of high exothermic reaction system.
