Abstract

A hot blast stove with a multi-layer rotary heat exchanging furnace comprises a stove body. An annular air box is arranged in the stove body and at the bottom of a hearth, a plurality of air ducts are arranged on the outer wall of the hearth fixedly and longitudinally at uniform intervals, the lower ends of the air ducts are connected and communicated with the annular air box, and a plurality of air holes are formed in positions, corresponding to the air ducts, of the inner wall of a combustion chamber. The multi-layer rotary heat exchanging furnace is arranged in the stove body and above the combustion chamber. By the hot blast stove, the contradictions that a vertical boiler is short in flue gas flow path and flue gas resistance is over high due to the purpose of lengthening the flue gas flow path are resolved. Therefore, flue gas of the heat exchanging technology flows flatly, and the flue gas in each layer in the multi-layer rotary heat exchanging furnace decelerates for counter steering. The rotary furnace has the biggest advantages that the flue gas flow path of a vertical boiler with the same diameter is maximized, and a heat exchanging process of covering fire with water is truly realized.

Description

At present, the following problem of ubiquity in various small-sized stove and accessorys: 1, can only burn coal, be difficult to utilize a lot of low-calorie fuel, limit fuel source, make many solid-state combustibles not only can not utilize simultaneously, become on the contrary the rubbish of contaminated environment; 2,, due to hot-blast stove wind entrance for once, fuel during use in burner hearth can not fully burn, and not only cause a large amount of black smokes, and the thermal efficiency is not high; 3, too short the reaching of flue gas flow caused the excessive problem of flue gas resistance in order to increase flue gas flow, and flue gas rises too fast, and heat transfer effect is bad; 4, smoke evacuation air-introduced machine in the past is all to be operated under the condition of high temperature, exists cost high, and maintenance rate is high, the disadvantage that spoilage is high.

Summary of the invention

Purpose of the present invention exists defect and deficiency for solving above-mentioned prior art exactly, and a kind of hot-blast stove with multi-layer rotating heat exchange flue is provided.

The technical scheme adopted is:

A kind of hot-blast stove with multi-layer rotating heat exchange flue, comprise body of heater, the top of body of heater is provided with the smoke evacuation cylinder, the top of body of heater is equiped with breeze fan, bottom in body of heater is provided with burner hearth, middle part in burner hearth is equiped with fire grate, the top that is positioned at fire grate in burner hearth is combustion chamber, the below that is positioned at fire grate is deashing chamber, the body of heater of deashing chamber is provided with shoot door, the side of bottom of furnace body is provided with a combustion fan, it is characterized in that: the bottom in body of heater is provided with an annular wind box around burner hearth, be respectively arranged with hot-blast outlet pipe on the outer wall of bottom of furnace body, an airduct, secondary air channel, one end of an airduct penetrates in deashing chamber, the other end of an airduct is connected with the wind pipe of combustion fan, and be connected, one end of secondary air channel is connected with annular wind box, and be connected, the other end of secondary air channel is connected with the wind pipe of combustion fan, and be connected, on the outer wall of burner hearth, longitudinal separation is installed with a plurality of wind channel tubes uniformly, the lower end of a plurality of wind channel tubes is connected and is connected with described annular wind box, have a plurality of wind hole with a plurality of wind channel tubes corresponding section on the inwall of combustion chamber, the top that is positioned at combustion chamber in body of heater is provided with Multi-layer thermal exchange rotation inner bag, the middle part of Multi-layer thermal exchange rotation inner bag is water jacket, the outside that is positioned at water jacket in Multi-layer thermal exchange rotation inner bag is flue rotating, every one deck heat exchange rotation inner bag all has fume inlet passage pipe and smoke-outlet flue pipe, and the fume inlet passage pipe is relative with the smoke-outlet flue pipe and establish, the fume inlet passage pipe of orlop heat exchange rotation inner bag is connected with combustion chamber, the smoke-outlet flue pipe of the heat exchange rotation inner bag of the superiors is connected with the smoke evacuation cylinder of upper of furnace body, and link.

Be equiped with fluidic device on above-mentioned smoke evacuation cylinder, described fluidic device comprises a blast pipe and a smoke exhaust fan, and the top of blast pipe penetrates in the smoke evacuation cylinder, and the bottom of blast pipe is arranged on outside the smoke evacuation cylinder, smoke exhaust fan is installed in the bottom of blast pipe, and the air outlet of smoke exhaust fan is connected with blast pipe.

The present invention compared with prior art has the following advantages:

1, the combustion system that adopts wind and secondary multiple spot air distribution to combine makes the thorough after-flame of fugitive constituent in fuel, reaches the effect of smokeless combustion, and during the boiler normal combustion, chimney be can't see cigarette at all.The present invention has an annular wind box in outer wall of combustion chamber fire grate bottom, wind box top and outer wall of combustion chamber are provided with a plurality of wind channel tubes, and combustion chamber is surrounded position by wind channel tube and has a plurality of Longitudinal Winds hole.Because combustion chamber is covered with the wind hole, eliminated oxygen supply dead angle in combustion chamber, burning is moved under the oxygen enrichment state, reached the purpose of fume-eliminating energy-saving.

2, multi-layer rotating flue heat transfer technology

This technology has well solved too short the reaching of vertical boiler flue gas flow and has caused the excessive contradiction of flue gas resistance in order to increase flue gas flow.Because the flue gas of this heat transfer technology is put down away, and flue gas every one deck in the multi-layer rotating flue carries out the counter steering deceleration.The advantage of rotation flue maximum is to make flue gas flow reach maximum in the vertical boiler of equivalent diameter, has really accomplished the heat transfer process of water bag fire simultaneously.

3, smoke evacuation fluidics

The purpose of researching and developing this technology is to be operated under the condition of high temperature expensive in order to solve the air-introduced machine of discharging fume in the past, the high maintenance rate, the drawback of high spoilage, because this smoke evacuation technology blower fan is operated in the normal temperature state, adopt common blower fan to solve the smoking problem of boiler, in practical application, boiler or hot-blast stove only need one meter chimney to work.
