Abstract

The utility model relates to a hot blast heater heat recovery device which comprises a combustion furnace body. An air inlet, a smoke outlet and a hot air outlet are placed on the combustion furnace body. The smoke outlet is communicated with a heat recovery device. The heat recovery device comprises a suction fan, a heat exchanger, a gas purifier and an air feeder. An air inlet of the suction fun and an air outlet of the suction fun are respectively communicated with the smoke outlet and the heat exchanger through pipelines. The heat exchanger is respectively communicated with the air purifier and the air inlet of the air feeder through pipelines. An air outlet of the air feeder is communicated with the hot air outlet. Smoke dust going out from the smoke outlet is settled and filtered through the hot blast heater heat recovery device to ensure that discharged air will not pollute the environment, and meanwhile through heat exchange of heat in the smoke dust, clean air obtained through heat exchange is sent to the hot air outlet by the air feeder again, and therefore the purpose of heat recovery is achieved.

Description

The hot-blast stove heat reclaim unit

Technical field

The utility model relates to the hot-blast stove technology, specifically is a kind of hot-blast stove heat reclaim unit.

Background technology

Use hot-blast stove at the dim common needs of the guarantor of grain-drying or greenhouse gardening, hot-blast stove comprises that mainly burner block, burner block are provided with air inlet, flue dust outlet and hot-blast outlet, air inlet connects that blower fan irritates high wind in the burner block and hot-blast outlet is communicated with the equipment that dryer and booth etc. need heating, the flue dust outlet connects induced-draught fan, exhaust gas dust after the burner block internal combustion is discharged, present this hot-blast stove is taken away a large amount of heats from the flue dust outlet, thereby causes the thermal efficiency not high.

The utility model content

The purpose of this utility model is to provide a kind of hot-blast stove heat reclaim unit, flue dust outlet at existing hot-blast stove connects a heat reclaim unit, the exhaust gas dust that heat reclaim unit exports out to flue dust carries out sedimentation and filters, make the gas of discharge free from environmental pollution, simultaneously with the heat in the exhaust gas dust by heat exchange, by pressure fan the clean hot air that heat exchange obtains is delivered to hot-blast outlet again, thereby realize the purpose of heat recovery.

For achieving the above object by the following technical solutions:

A kind of hot-blast stove heat reclaim unit, comprise that burner block, burner block are provided with air inlet, flue dust outlet and hot-blast outlet, it is characterized in that: the flue dust outlet is communicated with a heat reclaim unit, heat reclaim unit comprises induced-draught fan, heat exchanger, gas purifier and pressure fan, the air inlet of described induced-draught fan and air outlet are communicated with flue dust outlet and heat exchanger by pipeline respectively, heat exchanger is communicated with the air inlet of gas purifier and pressure fan respectively by pipeline, and the air outlet of pressure fan is communicated with hot-blast outlet.

Described heat exchanger comprises inner chamber body and outer chamber, inner chamber body is placed in outer chamber inside, the outer wall of inner chamber body is provided with some fin, be provided with import and escape pipe at the top of inner chamber body, wherein import is communicated with the air outlet of induced-draught fan by pipeline, the bottom of escape pipe is lower than the position of import, escape pipe is communicated with gas purifier by pipeline, the bottom of inner chamber body is provided with dust collection chamber, also be provided with the gas outlet on described outer chamber, the gas outlet is communicated with the air inlet of pressure fan by pipeline.

Described gas purifier comprises clean room, air inlet pipe and exhaust outlet, and the air inlet pipe lower end stretches under the liquid side to the clean room, and exhaust outlet is arranged on the top of clean room.

The utility model can carry out heat exchange by heat exchanger with the exhaust gas dust of directly discharging with a large amount of heats from the flue dust outlet originally, heat is changed the clean hot-air in back to be sent from hot-blast outlet again by pressure fan, and dust is collected by sedimentation, can be used as fertilizer, and poisonous gas is by discharging behind the gas purifier filtration, purification again, play catharsis simultaneously in the heat recovery recycling, guarantee that effluent is free from environmental pollution.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is internal structure schematic diagram of the present utility model.

The specific embodiment

As Fig. 1, shown in 2, a kind of hot-blast stove heat reclaim unit, comprise burner block 1, burner block 1 is provided with air inlet 11, flue dust outlet 12 and hot-blast outlet 13, flue dust outlet 12 is communicated with a heat reclaim unit, heat reclaim unit comprises induced-draught fan 21, heat exchanger 22, gas purifier 23 and pressure fan 24, the air inlet of described induced-draught fan 21 and air outlet are communicated with flue dust outlet 12 and heat exchanger 22 by pipeline respectively, heat exchanger 22 is communicated with the air inlet of gas purifier 23 and pressure fan 24 respectively by pipeline, and the air outlet of pressure fan 24 is communicated with hot-blast outlet 13.

Described heat exchanger 22 comprises inner chamber body 221 and outer chamber 222, inner chamber body 221 is placed in outer chamber 222 inside, the outer wall of inner chamber body 221 is provided with some fin, be provided with import 223 and escape pipe 224 at the top of inner chamber body 221, wherein import is communicated with by the air outlet of pipeline with induced-draught fan 21, the bottom of escape pipe 224 is lower than the position of import, escape pipe 224 is communicated with gas purifier 23 by pipeline, the bottom of inner chamber body 221 is provided with dust collection chamber 225, also be provided with the gas outlet on described outer chamber 222, the gas outlet is communicated with by the air inlet of pipeline with pressure fan 24.

Described gas purifier 23 comprises clean room, air inlet pipe and exhaust outlet, and the air inlet pipe lower end stretches under the liquid side to the clean room, and exhaust outlet is arranged on the top of clean room.

The utility model will export out the inner chamber body that the waste gas that has a large amount of heats is sent to heat exchanger from flue dust by induced-draught fan earlier, because waste gas can make the cavity of inner chamber body heat after entering inner chamber body, outer wall in inner chamber body is provided with some fin, the heat of waste gas by internal chamber wall and fin internally, cold air heats between the outer chamber, hot-air after the heating is sent to hot-blast outlet through the gas outlet by pressure fan, thereby realizes the recovery of heat.

After waste gas enters inner chamber body on the other hand, wherein dust can slowly be deposited to the dust collection chamber of bottom in inner chamber body, can work as the fertilizer recycling, and poisonous gas can enter in the clean room of gas purifier through escape pipe and air inlet pipe, filtration through the liquid in the clean room, from the exhaust outlet exhaust at top, clean room, do not pollute the environment at last.
