Description
Technical field
The invention belongs to drying device field, be specifically related to a kind of used heat of drying for W-Gum and utilize type starch pneumatic drier.
Background technology
Pneumatic drier is a kind of continuous, efficient fluidization of solid drying plant, has been successfully applied to corn and potato starch, and the final of protein one class powdery, sheet material is dried.Starch pneumatic drier uses steam to heat to radiator element as thermal source, makes by radiator element, to become hot blast through the freezing air of air inlet port and air filter and enter in drying tube under the effect of blower fan.The material being dried enters in drying tube by screw feeder, and it is material suspended in drying tube that high speed hot gas flow makes to be dried, and changes by caliber the air pulse producing, and material is constantly rolled, and at air-flow, carries secretly and in course of conveying, sloughs moisture content.The shortcoming of the starch pneumatic drier generally using on above-mentioned market is directly to enter in atmosphere after utilizing live steam to complete primary drying as thermal source and by the hot blast of drying tube, taken away a large amount of heats, freezing air is become to hot blast and need a large amount of heats, increased the production cost of Subscriber Unit, and waste gas directly enters in air, polluted factory's environment around, and the dust in waste gas spreads in and in air, has also become potential safety hazard, neither energy-conservation, not environmental protection again.
Summary of the invention
Object of the present invention is just to overcome above-mentioned deficiency, provides a kind of used heat that effectively utilizes high-temperature condensation water and high-temp waste gas to utilize type starch pneumatic drier.
Key problem in technology of the present invention is to add airheater and exhaust gas washing tower, by exhaust gas washing tower, after filtering, high-temp waste gas send with airheater as thermal source, and utilize the thermal source of high-temperature condensation water as airheater, by two kinds of used heat, the freezing air in airheater is heated, in solution prior art, directly buy raw steam large as thermal source cost, pollute heavy problem, its concrete technical scheme is: a kind of used heat utilizes type starch pneumatic drier, comprise the screw feeder that pipeline connects in turn, drying tube and cyclonic separator, described drying tube connects induced draft fan, characterized by further comprising airheater, described induced draft fan connects airheater, described airheater top is provided with road import after thermal source front road import and thermal source, thermal source front end inlet pipeline connects high-temperature condensation water pipeline, after described thermal source, road inlet pipeline connects exhaust gas washing tower top venting port, exhaust gas washing tower top is provided with water of condensation import, bottom is provided with exhaust gas inlet, described exhaust gas inlet pipeline connects the exhaust port of cyclonic separator pipe end, in described exhaust gas washing tower tower body, be distributed with successively from top to bottom six layers of column plate.
As preferably, described airheater comprises housing, in housing, be provided with front road heating tube and rear road heating tube, described front road heating tube and rear road heating tube are finned tube, described housing top correspondence is provided with road import after thermal source front road import that Yu Qian road heating tube and rear road heating tube connect and thermal source, and described housing separately offers air intlet.
As preferably, described airheater blast inlet is connected with air filter.
Beneficial effect of the present invention: the present invention greatly reduces running cost and reduced environmental pollution.
