Description
Technical field
The invention belongs to drying device field, be specifically related to a kind of heat utilization type starch pneumatic drier dried for cornstarch.
Background technology
Pneumatic drier is a kind of fluidization of solid drying equipment continuous, efficient, has been successfully applied to corn and potato starch, and protein one class powdery, the final of sheet material are dried.Starch pneumatic drier uses steam as thermal source and heats to fin, makes to become hot blast through the cold air of air inlet port and air cleaner by fin and enter in drying tube under the effect of blower fan.The material being dried is entered in drying tube by screw feeder, and it is material suspended in drying tube that velocity heated gas makes to be dried, and changed the air pulse produced by caliber so that material constantly rolls, and sloughs moisture content in air-flow carries course of conveying secretly.The shortcoming of the starch pneumatic drier commonly used on above-mentioned market is to utilize live steam to be directly discharged in air as thermal source and after completing primary drying by the hot blast of drying tube, take away substantial amounts of heat, cold air is become hot blast and needs substantial amounts of heat, add the production cost of Subscriber Unit, and waste gas is directly discharged in air, pollutes the environment around factory, and the dust in waste gas fills the air and the most also become potential safety hazard, the most energy-conservation, the most not environmentally.
Summary of the invention
The purpose of the present invention is that and overcomes above-mentioned deficiency, it is provided that a kind of heat utilization type starch pneumatic drier effectively utilizing high-temperature condensation water and high-temp waste gas.
nullThe key problem in technology of the present invention is to add air heater and exhaust gas washing tower，Send with air heater as thermal source after high-temp waste gas being filtered by exhaust gas washing tower，And utilize high-temperature condensation water as the thermal source of air heater，By two kinds of used heat, the cold air in air heater is heated，Solve that prior art is directly bought raw steam big as thermal source cost，The problem polluting weight，Its concrete technical scheme is: a kind of heat utilization type starch pneumatic drier，The screw feeder connected including sequentially pipeline、Drying tube and cyclone separator，Described drying tube connects air-introduced machine，Characterized by further comprising air heater，Described air-introduced machine connects air heater，Described air heater top is provided with road import after thermal source front road import and thermal source，Thermal source front road inlet pipeline connects high-temperature condensation water pipeline，After described thermal source, road inlet pipeline connects exhaust gas washing tower top exhaust outlet，Exhaust gas washing tower top is provided with condensed water import，Bottom is provided with exhaust gas inlet，Described exhaust gas inlet pipeline connects the exhaust port of cyclone separator pipe end，Six layers of column plate it have been sequentially distributed from top to bottom in described exhaust gas washing tower tower body.
As preferably, described air heater includes housing, it is provided with front road in housing and adds heat pipe and rear road adds heat pipe, described front road adds heat pipe and to add heat pipe be finned tube in rear road, described housing tip is correspondingly arranged on and adds heat pipe with front road and rear road adds road import after the thermal source front road import and thermal source that heat pipe is connected, and described housing separately offers air intlet.
As preferably, described air heater air inlet connects air cleaner.
Beneficial effects of the present invention: the present invention greatly reduces operating cost and decreases environmental pollution.
