Abstract
The invention relates to a continuous vacuum dynamic sublimation and desublimation machine, which belongs to the technical field of heat exchange and is suitable for separation refining of chemical products with sublimation characteristics. The continuous vacuum dynamic sublimation and desublimation machine is integrally formed by welding a vertical sublimation cylinder and a horizontal desublimation cylinder together through a sublimation gas pipe, wherein the vertical sublimation cylinder is externally provided with a hot oil jacket and internally provided with a heating plate, the horizontal desublimation cylinder is externally provided with a semi-circular cooling water coiler and internally provided with a shoveling plate, a driver drives a chain wheel to drive the entire equipment to rotate towards one direction, crude products are uniformly pushed to the sublimation cylinder, provided with inert particles in advance, through a spiral pushing mechanism, the preheated mechanical fluidized inert particles enable sublimates to sublimate quickly, and sublimated gas enters the desublimation cylinder through the sublimation gas pipe, and is cooled by prearranged and cooled fine powdery particles which are continuously shoveled and scattered by the shoveling plate, and desublimated on powdery particles. Because the fluidized inert particles are used for heating for sublimation, the sublimation is free from the influence of thermal resistance of impurities in the crude products, and because the sublimated gas is desublimated on the flowing and scattered fine powdery particles, the products are further free from shoveling so that the collection and the discharge of the products are simple and humanized.
Description
Affiliated technical field
The present invention relates to a kind of continuous vacuum dynamic sublimating and condensing machine, belong to technical field of heat exchange, be applicable to chemical products separation and purification with distillation characteristic.
Background technology
Present many chemical products distillations still rest on batch (-type) sublimating and condensing state, tie up to the more crude product of disposable adding in the sublimator, and thermal source is located at the bottom of device, and along with distillation, the non-distillation impurity in the crude product just remains in the bottom and constantly thickens, and thermal resistance increases thereupon.The heat of sublimation source temperature that has from beginning to finishing, the front and back temperature difference up to 50 remainings (℃).The impurity residual layer influences the speed of distillation greatly, and too high sublimation temperature also can cause and increase side reaction, has a strong impact on the quality and the recovery rate of product.The chemical products that have are very special, as producing pyrogallic acid through decarboxylic reaction earlier by gallic acid, pyrogallic acid distillation immediately, because the pyrogallic acid melting temperature is lower than the decarboxylic reaction temperature, the molten pyrogallic acid can be agglomerating with various impurity bondings, so the patent No.: 200810201428.The sublimating and condensing machine of 7 patterns is unsuitable for the distillation of this rerum natura material, sublimates and adopts the dividing wall type device of sublimating mostly, and distillation gas is sublimated on the wall of device of sublimating, and it is very arduous abominable that sublimate the down operation of thing of shovel is struck from wall in the back of stopping.
Summary of the invention
The object of the invention provides a kind of continuous vacuum dynamic sublimating and condensing machine, preset inert particle in the distillation machine, also join continuously in the inert particle that is mechanical fluidisation state and preheating behind the admixture inert particle in the distillation crude product, crude product powder or particle reach sublimation temperature rapidly and distil contact heating with the great inert particle of specific area after, distillation gas advance to sublimate in the machine with preset shed by flight under cooling elaboration powder body contact, the gas that distils is just sublimated and is being on the elaboration powder body of flow dispersion shape.
Technical solution of the present invention is: continuous vacuum dynamic sublimating and condensing machine is welded by vertical distillation cylindrical shell and the horizontal cylindrical shell two parts of sublimating, and it is by the crude product feed well, the pusher driving machine, the spiral pusher machine, sprocket wheel, bearing block, driving machine, the rotating shaft of distillation cylindrical shell, the distillation cylindrical shell, hot-oil jacket, interior heating plate, manhole, tubular electrothermal element, screen pack, the distillation flue, the flight retainer plate, the semicircle cooling water coil, the location short slab, flight, the cylindrical shell of sublimating, the tube of sublimating rotates outer shroud, the swivel bearing wheel, annular is girth sheets fixedly, the product overflow baffle, the product storage tank, exhaust gas filter, discharging opening, band O shape circle central shaft (the cooling water swivelling union of holding concurrently), vacuum exhaust pipe, formations such as vacuum pumping opening.Be characterized in: the distillation cylindrical shell is electrically heated hot-oil jacket in addition, in establish with polylith that hot-oil jacket is communicated with in heating plate, preset inert particle in the distillation cylindrical shell, the cylindrical shell peripheral hardware semicircle cooling water coil of sublimating, in establish the polylith flight and preset the product powder body of elaboration level quality, the product storage tank is made at the end socket position, and product advances the product storage tank through the baffle plate that overflows, the distillation flue welded connection distillation cylindrical shell and the cylindrical shell end socket center of sublimating; One of equipment swivel bearing is located on the distillation cylindrical shell rotating shaft, and another swivel bearing that is located under the cylindrical shell rotation outer shroud of sublimating is taken turns, and driving machine drives the sprocket wheel on the distillation cylindrical shell rotating shaft and drives integral device and rotates to a direction; The distillation cylindrical shell rotating shaft that the outer tube of pushing spiral passes the band O-ring seals enters the distillation cylindrical shell, crude product in the crude product feed well is input in the inert particle, distillation gas passes screen pack and enters the cylindrical shell of sublimating, the powder body that presets of cooling is taken up by flight and is trickled down, the distillation gas of heat is sublimated on the powder body, and the product storage tank is gone in the elaboration powder body overflow of being on the increase; The central shaft that fixed vacuum exhaust pipe passes the band O-ring seals enters the interior product storage tank position of cylindrical shell of sublimating, end at it is established exhaust gas filter, end outside the cylindrical shell of sublimating is established vacuum pumping opening, band O-ring seals central shaft double as cooling water swivelling union is to semicircle cooling water coil input (going out) cooling water.
Inert particle in the distillation cylindrical shell is by heating plate heating in the large tracts of land, crude product powder body is dispersed in the great inert particle of specific area, be heated distillation rapidly, high-melting-point impurity is no longer as play negative thermal resistance effect in the batch (-type) sublimator in the heated crude product, and play the distillation heat carrier as inert particle, help distilling and remain on lower best sublimation temperature for a long time, reducing side reaction to greatest extent produces, treat in the inert particle high-melting-point impurities accumulation to more for a long time, take out with inert particle and carry out organic substance and the organic carbon heating is burnt but.Distillation gas is sublimated on pre-cooled product powder body, and be covered with the polytetrafluoroethylene (PTFE) thin plate at the flight position of contact distillation gas, avoid sublimating and sublimate on the stainless steel surfaces of thing being difficult to peel off, help long period operation running, it is user-friendly for operation to help sublimating, and improves the quality of products and reduces product loss.
