Abstract
The utility model discloses a hot tube hot-air furnace, being composed of a fume furnace and a heat exchanger. The inner of the fume furnace is provided with a combustion chamber and two cyclone combustion chambers which are enclosed by a furnace wall, a furnace top, a grate and a furnace arch. The heat exchanger is directly connected with the fume outlet of the fume furnace. The fume comes out of the furnace and directly goes to the heat exchanger to heat the cold air in the heat exchanger, and then the air is transferred into a roadway. The utility model has the advantages of sufficient combustion of the fuel and high thermal efficiency.
Description
The utility model belongs to the combustion apparatus that uses solid fuel, and relates to a kind of heat pipe hot-blast stove.
At present, the heating and ventilation of the mine laneway of northern China all adopts steam boiler to produce steam, by vapours the air heat in the tubulation air heat exchanger is delivered in the tunnel then.Adopt this mode to send hot blast, heat loss is very big, and the thermal efficiency is very low.And produce steam and need big water gaging, also will be for water through handling, this has wasted a large amount of industrial chemicals and equipment again, and steam boiler belongs to pressure vessel in addition, and the security requirement height needs professional technical operation, and the complete equipment cost is also high.
The purpose of this utility model is to overcome the deficiencies in the prior art, and hot pipe technique and hot stove technical tie-up are used, and finds a kind ofly directly to add hot-air, efficient height, easy to operate heat pipe hot-blast stove with flue gas without steam.
For achieving the above object, the utility model adopts a smoke combustion stove and a heat exchanger combination, and the smoke combustion stove surrounds combustion chamber and cyclone combustion chamber by furnace wall, fire grate, chimney arch, and heat exchanger directly is connected with the outlet of smoke combustion stove.Hot flue gas arrives heat exchanger after coming out from the smoke combustion stove, and high-temperature flue gas is sent into the tunnel with the heating of the cold air in heat exchanger back by pipeline.
The utility model has the advantages that, combustion furnace and hot pipe technique are gathered together cleverly that changed the tunnel to live traditional air supply mode, fuel combustion is abundant, can save great deal of raw materials, thermal efficiency height.

Fig. 3 is a left view of the present utility model;
Fig. 4 is the G-G cutaway view of the utility model Fig. 1;
Fig. 5 is the H-H cutaway view of the utility model Fig. 1.
The utility model is made up of smoke combustion stove and heat exchanger 7.The smoke combustion stove is made up of furnace wall 3, furnace roof 4, coal bunker 1, fire grate 5 and chimney arch 2, different with plain cylindrical furnace is that inside does not have drum and tube bank, furnace wall and fire grate surround combustion chamber and two cyclone combustion chamber C, D with the smoke combustion furnace interior, between cyclone combustion chamber C, D, there is the cigarette hole to be communicated with, on the top of cyclone combustion chamber C a wind pushing hole E is arranged, so that fresh air is sent in the stove.In cyclone combustion chamber D bottom a venthole F is arranged, be connected with a heat exchange of heat pipe 7 at venthole F place by pipe, heat exchange of heat pipe is made up of framework, dividing plate and heat pipe, is welded with double-deck side plate 8 on framework, is filled with insulation material between double-deck side plate.At the middle part dividing plate is arranged, heat pipe 9 is installed between top board and base plate, heat pipe 9 passes dividing plate and forms upper and lower two parts, is set with fin on the heat pipe of the first half.In both sides, heat exchange bottom, smoke inlet and outlet are arranged respectively; In the heat exchanger both upper ends thereof air entrance and exit is arranged.
During use, at first by the coal bunker loading coal, fall fire grate front end again, driving reciprocal grate by motor via reducer then seesaws and gradually coal is transported to middle part and rear portion, and ignited up to after-flame, fall into ashcan then, by transporting to outside the stove with the supporting slag remover of this stove, the high-temperature flue gas that coal combustion produces is by preceding, flow out between the rear arch, cross the tracery wall of rear arch top, enter first cyclone combustion chamber and produce tangential rotation, unburnt little carbon granules is burnt away until after-flame, and below separated the falling of unburnt carbon granules of larger particles, regularly claw by following ash door.High-temperature flue gas enters the second cyclone combustion chamber D by the first cyclone combustion chamber C through the cigarette hole, with fully mix from the cold air that top wind pushing hole E introduces by blower fan, make between the cigarette temperature to 550 °~600 °, high-temperature flue gas arrives the heat exchange of heat pipe bottom that is attached thereto by the exhanst gas outlet F of the second cyclone combustion chamber bottom then, wash away heat pipe and make the heat pipe heating, fresh cold air is entered by heat exchanger top, be heated to when flowing through heat pipe about 150 ℃, be sent to tunnel, well head etc. by pipeline then and be down-hole heating, ventilation.
