Technology contents
The purpose of this utility model is a kind of coal-fired hot-blast stove of design, with the thermal efficiency of further raising hot-blast stove, and the manufacturing and the use cost of reduction equipment.
Its main technical schemes is external of metal furnaces shell to be set, and in body of heater and shell, form the air channel, coal filling hole and air door are set on the wall of body of heater, chimney is arranged above body of heater, air inlet and air outlet are set on the shell, in the shell above body of heater heat transfer zone is set, heat-exchanger rig is arranged in the heat transfer zone.
Described heat-exchanger rig is made of the heat pipe that is vertically arranged in one by one above the body of heater, and by burner hearth and chimney in the heat pipe connection body of heater.
Described heat-exchanger rig also can be made of the heat pipe that is horizontally arranged in the body of heater top one by one, heat pipe has two groups up and down at least, utilize dividing plate that air intake district and return air district are set respectively at the two ends of heat pipe, wherein the air intake district is communicated with air inlet and superposed one group of heat pipe, the return air district is communicated with superposed one group of heat pipe and the one group of heat pipe that is positioned at its underpart, and the other end that is positioned at one group of heat pipe of foot is communicated with the air channel.
Also can be on body of heater the connection chimney, the case that is connected on the shell is set outside chimney, and between chimney and case, forms chuck, connect spiral helicine fin on the chimney in chuck, air inlet is positioned at the upper end of case.
The wind-guiding swash plate is set on the inwall of the shell between heat transfer zone and the air channel.Furnace body outer wall in the air channel connects fin.
The utility model has the advantages that because body of heater is the metal manufacturing, and heat transfer zone and heat-exchanger rig are set above body of heater, thereby, can make full use of the heat that is produced when the heat of body of heater and flue gas carry out heat exchange by heat-exchanger rig, the thermal efficiency is improved greatly; Used heat-exchanger rig can adopt various ways, and as heat pipe is vertically arranged in the heat transfer zone, flue gas passes through in heat pipe, and hot blast utilizes the outer hot blast of flue gas heating tube scorching hot in the pipe from the outer process of heat pipe; Also heat pipe can be horizontally arranged in the heat transfer zone, flue gas process outside managing at this moment, hot blast passes through in managing, and enters further heating in the following air channel again, after air outlet drain in the booth; One chimney can also be set on body of heater, one case is installed outside chimney, form a chuck, air inlet is arranged at the case upper end, spiral helicine fin is set again, in chuck when flue gas rises in chimney, hot blast in heating fin and the chuck, hot blast enters further heating in the air channel of bottom under the effect of the blower fan that is installed on air inlet, in air outlet drained into booth, all these methods had all improved heat exchange efficiency effectively again; In addition, because used fuel is coal, the cost of therefore making hot-blast stove is all low than oil firing with the cost that uses hot-blast stove, and the popularization that helps this technology is with universal.

The specific embodiment
As shown in the figure:
In metal body of heater 5 outsides shell 3 is set, and in body of heater 5 and shell 3 formation air channel 9, hot blast can further be heated up in this air channel, coal filling hole 10 and air door 8 are set on the wall of body of heater 5, wherein coal filling hole is used for coal in stove, air door is used for air blast in stove, chimney 1 is arranged above body of heater 5, air inlet 11 and air outlet 7 are set on the shell 3, air inlet wherein is used for air blast in the air channel, and air outlet is connected with external pipe, is used for heated wind is delivered in the booth, in the shell 3 above body of heater 5 heat transfer zone 20 is set, in the heat transfer zone 20 heat-exchanger rig is arranged.
Described heat-exchanger rig can be made of the heat pipe 2 that is vertically arranged in one by one above the body of heater 5, and by burner hearth and chimney 1 in the heat pipe 2 connection bodies of heater 5, the flue gases in the body of heater 5 pass through in every heat pipe 2, enter chimney 1.On the inwall of the shell 3 between heat transfer zone 20 and the air channel 9 wind-guiding swash plate 4 is set, enters in the air channel with helical form with the guiding hot blast, body of heater 5 outer walls in air channel 9 connect fin 6, to improve heat exchange efficiency.
Heat-exchanger rig also can be made of the heat pipe 14 that is horizontally arranged in body of heater 5 tops one by one, heat pipe 14 has two groups up and down at least, utilize dividing plate 13 that air intake district 12 and return air district 15 are set respectively at the two ends of heat pipe 14, wherein air intake district 12 is communicated with air inlet 11 and superposed one group of heat pipe 14, return air district 15 is communicated with superposed one group of heat pipe 14 and the one group of heat pipe 14 ' that is positioned at its underpart, and the other end that is positioned at one group of heat pipe 14 ' of foot is communicated with air channel 9.During work, hot blast enters the air intake district from air inlet, enter the return air district through superposed one group of heat pipe, one group of heat pipe below being positioned at it enters the air channel again, discharge from air outlet at last, when wind in heat pipe through out-of-date, scorching hot flue gas is from the outer process of heat pipe, two kinds of fluid generation heat exchanges, make wind obtain heating, after hot blast enters the air channel, also can further heat, had higher temperature through the hot blast after the heating for multiple times, deliver in the booth and can effectively improve canopy temperature, heat pipe can be provided with several groups, and the group number is many more, and effect is good more.
Can also be on body of heater 5 connection chimney 1, the case 16 that is connected on the shell 3 is set outside chimney 1, and, connect spiral helicine fin 18 on the chimney 1 in chuck 17 at chimney 1 and 16 formation of case chuck 17, at this moment air inlet 11 should be positioned at the upper end of case 16.This structure is fairly simple comparatively speaking, and wind enters chuck from air inlet, enters in the following air channel further heating again, but both wind-guiding of helical form fin can conduct heat again, for some small-sized hot-blast stoves, adopt this structure more reasonable.
