Abstract

The utility model relates to a pulse pipe hot air furnace, which belongs to air heating equipment. The utility model is composed of a pulse pipe heat exchanger main body 4, a coal-fired burner 3, a dust removal and filtering flue 7, a dust remover 8, a fume guiding blower 10, and a chimney 9. The utility model is characterized in that the heat exchanger 4 is composed of three or more than three pipe bundling heat exchanging sections 11 and two or more than two diffusion cavities 12. The utility model has the advantages of short column pipe length, small swell increment, and even heat exchange. The utility model can be put vertically for cleaning ash conveniently.

Description

The pulse tube hot-blast stove
The utility model belongs to the drying system air heating plant.
The pipe type heat transfer hot-blast stove is the common a kind of drying air heating apparatus of China, carries out heat exchange owing to relatively be suitable for coal-fired flue-gas and air, so be widely used in the drying system of industries such as grain, food, chemical industry, medicine.But form the heat exchange backhaul because the conventional tubular heat exchanger adds dividing plate in tube bank, so ubiquity is longer such as tubulation, swell increment is big, easily snaps; It is even inadequately to dispel the heat, and the thermal efficiency is on the low side; Be suitable for horizontal layout, the big and material of floor space requires high, not problem such as easy-to-clean ash.
The purpose of this utility model provides that a kind of tubulation length is shorter, and swell increment is less, and heat exchange is more even, can vertical layout and be convenient to the novel air firing equipment of deashing.
The purpose of this utility model can realize by following measure: pulse tube hot-blast stove described in the utility model comprises pulse tube heat exchanger, coal-fired combusting device, depositing dust transition flue duct, deduster, draws cigarette blower fan, chimney.Heat exchanger is made of tube bank heat exchanging segment and two or more diffusion chamber more than three or three.The tube bank heat exchanging segment vertically assembles for folded mutually at interval with diffusion chamber.The heat exchange amount requires when big, and heat exchanger also can be made into to be installed series connection side by side and use more than two, so can be designed to different big or small hot-blast stoves
Advantage of the present utility model is: simple in structure, volume is little, and cost is low, makes easy for installation, safe in utilization, the short swell increment of tube bank length is little, long service life, thermal efficiency height, energy consumption is low, can use bituminous coal, can vertical layout be convenient to deashing, highly versatile also can be made into large, medium and small type series of products.Not only be suitable for the supporting use of various drying equipments, but also can be used for booth, Greenhouse Heating.
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is the longitudinal sectional drawing of heat exchanger main body.
Describe structure of the present utility model and operation principle in detail below in conjunction with accompanying drawing:
The pulse tube hot-blast stove comprises heat exchanger main body 4, coal-fired combusting device 3, depositing dust transition flue duct 7, deduster 8, smoke induced draught fan 10, chimney 9, heat exchanger main body 4 is made of the tube bank heat exchanging segment more than three or three 11 and two or more diffusion chamber 12, tube bank heat exchanging segment 11 on the heat exchanger 4 vertically assembles for folded mutually at interval with diffusion chamber 12, the height of the tube bank heat exchanging segment 11 on the heat exchanger 4 is a 0.4-0.6 rice, and the height of diffusion chamber 12 is a 0.2-0.3 rice.
Tubulation on the tube bank heat exchanging segment is staggered front to back arrangement to strengthen exchange capability of heat.Bituminous coal is after coal filling hole 2 drops into the combustion chamber, restrain interior heat release through the tube bank heat exchanging segment that depositing dust transition flue duct 7 enters in the heat exchanger earlier by the elevated temperature heat flue gas that coal-fired combusting device 3 burnings form, entering diffusion chamber 12 then carries out entering next heat transfer process again after the temperature equalization, finish to enter deduster 8 further dedustings by flue until heat transfer process, draw and be pressed into chimney 9 and enter atmosphere by drawing cigarette blower fan 10 through the flue gas of dedusting through the heat exchanger top.The remaining slag that burns is then discharged by cleaning door 1.And the heating process of the air bright air that is nature is introduced into by air intake 5 that pipe external space transversal flow tube bank outer wall on the heat exchanger top tube bank heat exchanging segment 11 carries out heat exchange and by the heat exchanger vertical direction after transversal flow is respectively restrained heat exchanging segment 11 successively from top to down, discharge through heat exchanger bottom exhaust outlet 6, draw by the air-heater on the drying machine then.

Claims (4)
