The working principle of the utility model are as follows:
Biomass combustion furnace generally includes combustion chamber 1 and convection heat-exchange chamber 2, biomass in combustion chamber 1 after combustion gasification,
High-temperature flue gas is flowed in convection heat-exchange chamber 2 in up and down reciprocatingly bending-like under the air-introduced machine 5 effect, and finally by the flue gas
Flue gas is introduced into filtering ponds 11 and filters by 6 discharge of outlet, air-introduced machine 5, and filtered flue gas is then flowed away by flue 7.This reality simultaneously
The first connecting tube 14, which is connected to, with the backwind tube 13 that novel utilization is drawn by flue 7 forms a circuit.The structure on the one hand can
To play cooling effect, exhanst gas outlet 6 generally requires to be no more than 120 DEG C, and temperature is excessively high to damage air-introduced machine 5, but past in practice
Toward uncontrollable 6 temperature of exhanst gas outlet, the utility model guarantees the normal work of air-introduced machine 5 using 13 cooled flue gas of backwind tube outlet 6
Make, the return air air pressure that air pressure is greater than in backwind tube 13 is discharged by exhanst gas outlet 6 for another aspect flue gas, will not be to convection heat-exchange chamber 2
Interior temperature impacts.In addition flue gas enters after flue 7 and does not drain directly, but acts on through backwind tube 13 and air-introduced machine 5
It is recycled into filtering ponds 11 and is filtered, both substantially increase filter effect, smokeless or few cigarette discharge also may be implemented substantially,
Meet national requirements for environmental protection.
In addition the utility model is equipped with a regulating mechanism in adapter cavity 8 and controls the flue gas pressure being discharged into filtering ponds 11
Power, as shown in figs. 2 to 4, flue gas enters in adapter cavity 8 through the second connecting tube 16 and lifting set 17 under normal circumstances, the filtering
Pipe 10 can spray flue gas, and when lifting drive 18 starts, the inner cover plate 20 and lifting set 17 decline together, and set
The outer cover plate 19 being placed in inner cover plate 20 declines also with inner cover plate 20 is synchronous, since inner cover plate 20 is placed in 19 middle part of outer cover plate
Groove in, 19 edge protrusion of outer cover plate can be first close to 8 lower surface of adapter cavity when decline, at this time be to block a part of screen pipe
10 stop spray flue gases, if at this time lifting drive 18 continue drive inner cover plate 20 decline, inner cover plate 20 again with institute
8 lower surface of adapter cavity abutting is stated, and blocks a part of screen pipe 10 again and stops spraying flue gas, is only stayed in lifting 17 lower ports of set
Thus 10 aerosol spraying of screen pipe can realize that three-level is adjusted.
Realize that flue gas three-level is adjusted by the way that the descending stroke of lifting drive 18 is set in advance in the present embodiment, Ye Jigen
Moving distance is set according to 19 adjustable height of outer cover plate, when 19 edge protrusion of outer cover plate offsets with 8 lower surface of adapter cavity, the liter
Drop driving device 18 is automatically stopped operation, continues to adjust if necessary, then operates the corresponding button restarting on control panel
Lifting drive 18 drives inner cover plate 20 to continue to decline.
