Design a kind of device for handling biomass electric power plant flue gas and Mist heat recovering, including biomass boiler, the life
The output end of material boiler is connected to different flow directions and obtains the first flue, the second flue, first flue gas
Pipeline, the second flue converge to be set successively for the 3rd flue, the 3rd flue from its input to output end
Have absorber, a chimney, the output end of the absorber be also connected with turn evaporator, condenser, the second heat exchanger, air blower,
Feed bin and screw(-type) feeder, are connected with the 3rd heat exchanger between the input and output end of second flue, and described
Three heat exchangers are connected with evaporator, and absorbing liquid is filled with the absorber.
In such scheme, First Heat Exchanger is provided between the output end and evaporator of the absorber.
In such scheme, input and the output end of the absorber are provided with filter.
In such scheme, the 3rd flue is provided with air-introduced machine between absorber and chimney.
Implement a kind of device for handling biomass electric power plant flue gas and Mist heat recovering of the present invention, have below beneficial to effect
Fruit：
The present invention can utilize biomass electric power plant residual heat from boiler fume drying biomass fuel, overall to lift biomass electric power plant
The efficiency of boiler；And the dust in the circulation solution washing flue gas of absorber is utilized, the dust content in tail gas is effectively reduced,
Dust pelletizing system structure is simplified simultaneously, improves overall operation reliability.
