The output end of substance boiler is connected separately with different flow directions and obtains the first flue, the second flue, first flue gas
Pipeline, the second flue converge for third flue, and the third flue is successively set from its input terminal to output end
Have an absorber, chimney, the output end of the absorber be also connected in turn evaporator, condenser, the second heat exchanger, air blower,
Feed bin and screw(-type) feeder, are connected with third heat exchanger between the input terminal and output end of second flue, and described
Three heat exchangers are connect with evaporator, and absorbing liquid is filled in the absorber.
In the above scheme, First Heat Exchanger is equipped between the output end and evaporator of the absorber.
In the above scheme, the input terminal of the absorber and output end are provided with filter device.
In the above scheme, the third flue is equipped with air-introduced machine between absorber and chimney.
The device for implementing a kind of processing biomass electric power plant flue gas of the present invention and Mist heat recovering, has below beneficial to effect
Fruit:
The present invention can use biomass electric power plant residual heat from boiler fume drying biomass fuel, whole to promote biomass electric power plant
The efficiency of boiler；And using the dust in the circulation solution of absorber washing flue gas, the dust content in tail gas is effectively reduced,
Dust pelletizing system structure is simplified simultaneously, improves overall operation reliability.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:

Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
A specific embodiment of the invention.
The device of a kind of processing biomass electric power plant flue gas of the present invention and Mist heat recovering, including biomass boiler 1, biology
The output end of matter boiler 1 is connected separately with different flow directions and obtains the first flue 3, the second flue 2, the first flue
3, the second flue 2 converges for third flue 16, and third flue 16 is successively arranged from its input terminal to output end
Absorber 4, air-introduced machine 8, chimney 9, the input terminal and output end of absorber 4 are provided with filter device 7, the output end of absorber 4
Also be connected in turn First Heat Exchanger 14, evaporator 5, condenser 6, the second heat exchanger 15, air blower 10, feed bin 11 and spiral to
Material machine 12 is connected with third heat exchanger 13, third heat exchanger 13 and evaporation between the input terminal and output end of second flue 2
Device 5 connects, and absorbing liquid is filled in absorber 4.
Biomass boiler 1, the second flue 2, the first flue 3, absorber 4, filter device 7, air-introduced machine 8, cigarette
Chimney 9 constitute smoke processing system, and biomass boiler 1, the second flue 2, third heat exchanger 13, evaporator 5, condenser 6,
Second heat exchanger 15, air blower 10 or biomass boiler 1, the first flue 3, absorber 4, First Heat Exchanger 14, evaporator
5, condenser 6, the second heat exchanger 15, air blower 10 constitute flue gas heat recovery system.
Working principle of the present invention is as follows:
