Description of the drawings
Fig. 1 is the structural representation of the power economized boiler of waste heat from tail gas recycling;
In figure:1- bodies of heater, 2- fire grates, 3- water tanks, 4- combustion chambers, 5- charge doors, 6- deashing chambers, 7- cleaning doors, 8- smoke evacuations Pipe, 9- heat exchange box, 10- spiral heat exchange tubes, 11- pipes, 12- outer tubes, 13- air inlets, 14- escaping pipes, 15- air-introduced machines, 16- appendixs, 17- pipe connecting pieces, 18- filler, 19- blocks, 20- delivery ports, 21- valves.
Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Refer to Fig. 1, a kind of power economized boiler of waste heat from tail gas recycling, including body of heater 1, the inside of the body of heater 1 Downside is provided with fire grate 2, and the upper end of body of heater 1 is provided with water tank 3, combustion chamber 4, combustion chamber are provided between the fire grate 2 and water tank 3 4 right side is provided with charge door 5, and the lower section of the fire grate 2 is provided with deashing chamber 6, and the right side of deashing chamber 6 is provided with cleaning door 7, cleaning door Switch gate (not shown) is installed on 7;The upper end of the body of heater 1 is provided with smoke exhaust pipe 8, and the lower end of smoke exhaust pipe 8 sets through water tank 3 Put, the upper right side of heat exchange box 9 is connected to after the upper end bending of smoke exhaust pipe 8, spiral heat exchange tube 10 is provided with inside heat exchange box 9, exchange heat The lower-left end of case 9 is connected with pipe 11, the upper end connection smoke exhaust pipe 8 of the spiral heat exchange tube 10, under spiral heat exchange tube 10 End connection pipe 11, the outside of the heat exchange box 9 is provided with outer tube 12, and the upper end center of outer tube 12 is provided with air inlet pipe 13, the lower end center of outer tube 12 is connected with escaping pipe 14, and the lower end of escaping pipe 14 is connected with appendix 16 by air-introduced machine 15, The other end of appendix 16 is connected inside body of heater 1 by pipe connecting piece 17, and the pipe connecting piece 17 is located at the top of fire grate 2, appendix 16 Inside connection combustion chamber 4.
When boiler carries out heating up water operation, fuel is placed on fire grate 2 by charge door 5, and the fuel after burning becomes coal Slag drops in deashing chamber 6, and by cleaning door 7 deashing can be easily carried out, and the heat heat exchange that fuel combustion is produced is fed water Water in case 3, it is possible to achieve supplying hot water, smoke exhaust pipe 8 can be discharged the air after burning, but in actual production, The heat of fuel combustion can not possibly completely transmit the water in feed-tank 3, have the partial heat can be by the flue gas in smoke exhaust pipe 8 to band Walk, now the flue gas in smoke exhaust pipe 8 can be through spiral heat exchange tube 10, and spiral heat exchange tube 10 is by the heat transfer in flue gas to heat exchange Medium in case 9, can improve the utilization ratio of the energy, but the heat in heat exchange box 9 also can be with internal helicoid heat exchanger tube Flow of flue gas in 10 is constantly lost in, and the particularly outer wall of heat exchange box 9 can constantly radiate, and traditional structure is in order to prevent heat exchange box 9 Radiating, can set up heat-insulation layer by the outer wall of heat exchange box 9, but heat-insulation layer is heat-insulated, also have fraction of heat and flow out, and The cost of heat-insulation layer is also of a relatively high;And outer tube 12 is additionally arranged outside heat exchange box 9 in this structure, so when outside heat exchange box 9 When the heat of wall scatters and disappears away, will enter in outer tube 12, the air in outer tube 12 is heated, and in outer tube 12 Air be constantly in flow regime, introduced in combustion chamber 4 through appendix 16 by air-introduced machine 15, such heat exchange box 9 scatter and disappear Heat has finally been returned in combustion chamber 4, realizes recycling, greatly reduces the loss of heat.
The upper end left side of the water tank 3 offers filler 18, coordinates on filler 18 and is provided with block 19.
The right side lower end of the water tank 3 offers delivery port 20, and valve 21 is provided with delivery port 20.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party Formula, in the ken that one skilled in the relevant art possesses, can be with the premise of without departing from this patent objective Make a variety of changes.
