Summary of the invention
The technical problem that the utility model will solve is to above-mentioned defective, provide a kind of simple in structure, soot emissions are few and fuel-saving boiler air feed fume extractor.
In order to solve the problems of the technologies described above, the utility model provides a kind of boiler air feed fume extractor with following structure, comprises boiler and chimney, and its design feature is to be provided with heat exchange box between boiler and the chimney; Heat exchange box comprises the casing of sealing, is provided with upper spacer and lower clapboard in the casing, and upper spacer and lower clapboard are separated into smoke input chamber, heat exchanging chamber and smoke output chamber with cabinets cavity, is provided with in the casing to pass heat exchanging chamber and cross smoke pipe with what smoke input chamber and smoke output chamber were communicated with; Smoke input chamber is communicated with the exhaust opening of boiler through smoke-intake pipe, and smoke output chamber is communicated with chimney through pipe, and casing is provided with the blast pipe that is communicated with heat exchanging chamber top, and the heat exchanging chamber bottom is communicated with the air inlet of boiler through discharge pipe.
Be provided with the polylith median septum in the said heat exchanging chamber, the polylith median septum is separated into a plurality of Heat Rooms that are communicated with successively with heat exchanging chamber, and the Heat Room that closes on smoke input chamber is communicated with blast pipe, and the Heat Room that closes on smoke output chamber is communicated with discharge pipe.
Be serially connected with smoke exhaust fan on the said pipe.
The air intake valve is housed on the said blast pipe, and blast pipe is communicated with breeze fan on the pipeline section between air intake valve and the casing.
The exhaust opening of said boiler is communicated with chimney through auxiliary smoke exhaust pipe, is serially connected with exhaust smoke valve on the auxiliary smoke exhaust pipe.
Said pipe stretches in the smoke output chamber, is provided with smoke intaking hole on the port closed of the pipeline section of pipe in smoke output chamber and the tube wall of this pipeline section.
The boiler air feed fume extractor of said structure, the flue gas that boiler combustion produces gets into smoke input chamber through smoke-intake pipe, gets into smoke output chamber by crossing smoke pipe again, is finally discharged by chimney through pipe; Air arrives boiler bottom through discharge pipe after blast pipe gets into heat exchanging chamber, to provide burning required oxygen.In the above-mentioned smoke evacuation air feed process, during flue gas process heat exchange box, carry out heat exchange with the air that gets in the heat exchanging chamber; Air is carried out preheating; The temperature of flue gas and dustiness all reduce greatly, that is to say that the dust content of discharging from chimney is little, temperature is low, helps protecting environment; And, can obviously improve furnace temperature by behind the air of the preheating entering boiler, the heat that fuel is produced is utilized, and has reached energy-conservation purpose, has practiced thrift fuel consumption accordingly.
To sum up, the utility model advantage is: simple in structure, soot emissions are few and fuel savings.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, boiler air feed fume extractor comprises boiler 1 and chimney 2, is provided with heat exchange box between boiler 1 and the chimney 2; Heat exchange box comprises the casing 3 of sealing; Be provided with upper spacer 4 and lower clapboard 5 in the casing 3; Upper spacer 4 is separated into the smoke input chamber 6 on top, the heat exchanging chamber 7 at middle part and the smoke output chamber 8 of bottom with lower clapboard 5 with casing 3 inner chambers, is provided with many mistake smoke pipes 9 that pass heat exchanging chamber 7 and smoke input chamber 6 and smoke output chamber 8 are communicated with in the casing 3; Smoke input chamber 6 is communicated with the exhaust opening of boiler 1 through smoke-intake pipe 10, and smoke output chamber 8 is communicated with chimney 2 through pipe 11, and casing 3 is provided with the blast pipe 12 that is communicated with heat exchanging chamber 7 tops, and heat exchanging chamber 7 bottoms are communicated with the air inlet of boiler 1 through discharge pipe 13.In order to make boiler obtain enough oxygen, on pipe 11, be serially connected with smoke exhaust fan 16, air intake valve 19 is housed on the blast pipe 12, blast pipe 12 is communicated with breeze fan 20 on the pipeline section between air intake valve 19 and the casing 3.Breeze fan 20 needs air intake valve 19 cuts out when opening, and smoke exhaust fan 16 can be opened with breeze fan 20 simultaneously, also can open separately, and when normally using, general opened smoke-discharging blower fan 16.
In order to improve the heat exchange effect; Make full use of the waste heat of flue gas; Following improvement can be done in heat exchanging chamber 7: be provided with polylith median septum 17 in the promptly above-mentioned heat exchanging chamber 7; Polylith median septum 17 is separated into a plurality of Heat Rooms 18 from top to bottom with heat exchanging chamber 7, is equipped with air passing hole 22 on the every median septum 17, and the air passing hole 22 on the adjacent median septum 17 is preferably each other away from avoiding upper-lower position corresponding; The mode that the utility model adopts the air passing hole 22 on the adjacent median septum 17 on the width of heat exchange box, to be oppositely arranged, air passing hole 22 is communicated with a plurality of Heat Rooms 18 from top to bottom in order.The Heat Room 18 that closes on smoke input chamber 6 is communicated with blast pipe 12, and the Heat Room 18 that closes on smoke output chamber 8 is communicated with discharge pipe 13.
