The purpose of this utility model is to realize like this, described a kind of biomass boiler with mixer, comprise cyclone-combustion stove, mixer, expansion chamber, tubular heat exchanger and chimney, described cyclone-combustion stove has into fuel port and air inlet, its design feature is that described mixer comprises mixing drum, charging aperture, compound outlet and agitator, the opening on mixing drum top is charging aperture, the centre of mixing drum is provided with agitator, the lower openings of mixing drum is compound outlet, and described compound outlet is connected with the fuel port that enters of cyclone-combustion stove; Rear portion at cyclone-combustion stove is connected with expansion chamber, is provided with tubular heat exchanger at the rear portion of expansion chamber, is provided with steamdrum device on tubular heat exchanger, rear portion at tubular heat exchanger is provided with gas holder, gas holder connects an air-introduced machine, and air-introduced machine connects chimney, and chimney is connected to wet scrubber.
The purpose of this utility model also can be achieved through the following technical solutions, described a kind of biomass boiler with mixer, and its feature is to be provided with the slag-drip opening for getting rid of dust in the bottom of expansion chamber.
The utlity model has following advantage: the utility model adopts mixer and cyclone-combustion stove, make the fossil fuel such as living beings and coal after pulverizing export the fuel port that enters that enters cyclone-combustion stove through compound by mixer, making living beings revolve tangential direction from of cyclone-combustion stove enters, air enters from the tangential direction of revolving of opposite face, reach abundant mixed combustion Heat of Formation flue gas, improve biomass combustion efficiency, hot flue gas reduces the discharge of flue dust below by the expansion chamber connecting at cyclone-combustion stove, through tubular heat exchanger, heat outputting steam, user is provided heat supply, flue dust through sedimentation is got rid of by chimney through air-introduced machine, thereby can make biomass combustion complete, free from environmental pollution, 2) efficiency of combustion is high, 3) no dust pollution, provides good operating environment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the layout schematic cross-section that enters fuel port and air inlet of the cyclone-combustion stove in Fig. 1.
Number in the figure explanation: cyclone-combustion stove 1, enters fuel port 2, air inlet 3, expansion chamber 4, blowoff valve 5, tubular heat exchanger 6, steamdrum device 7, air-introduced machine 8, chimney 9, gas holder 10, mixing drum 11, charging aperture 12, agitator 13.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, a kind of biomass boiler with mixer provided by the utility model, comprise cyclone-combustion stove 1, mixer, expansion chamber 4, tubular heat exchanger 6 and chimney 9, described cyclone-combustion stove 1 has into fuel port 2 and air inlet 3, enter fuel port 2 for entering biomass fuel, air inlet 3 is for leading to into air, make full combustion of fuel, its design feature is: described mixer comprises mixing drum 11, charging aperture 12, compound outlet and agitator 13, the opening on mixing drum 11 tops is charging aperture 12, the centre of mixing drum 11 is provided with agitator 13, the lower openings of mixing drum 22 is compound outlet, described compound outlet is connected with the fuel port 2 that enters of cyclone-combustion stove 1, be connected with expansion chamber 4 at the rear portion of cyclone-combustion stove 1, expansion chamber 4 bottoms can be provided with slag-drip opening 5 for getting rid of flue dust, be provided with tubular heat exchanger 6 at the rear portion of expansion chamber 4, its effect is for carrying out heat exchange, cyclone-combustion stove 1 thermal power transfer of hot flue gas forming of burning is entered in the steamdrum device 7 of portion provided thereon, steamdrum device 7 is prior art, such as steam storage tank, its effect is to provide heat energy and uses to user, be provided with gas holder 10 at the rear portion of tubular heat exchanger 6, gas holder 10 is for storing the flue gas after heat exchange, gas holder 1 connects an air-introduced machine 8, air-introduced machine 8 connects chimney 9.Operation principle is: make the fossil fuel such as living beings and coal (particle diameter is 5 millimeters of following living beings and connys) after pulverizing export the fuel port that enters that enters cyclone-combustion stove through compound by mixer, making living beings and conny revolve tangential direction from of cyclone-combustion stove enters, air revolves tangential direction from another of opposite face and enters, living beings and conny fuel are through the Heat of Formation flue gas that fully burns, hot flue gas is through expansion chamber 4 sedimentation ash disposal, enter again the heat exchange of tubular heat exchanger 6, finally flue gas is received to wet scrubber (figure does not draw) through air-introduced machine from chimney 9, the efficiency of dust collection that this wet scrubber is less than 5 μ m dust to particle diameter is high, reach 5~8 years service life.Wet scrubber compact conformation, takes up room little, and water consumption is little, and the floor space of 5~7 cubic metres of dust-contained airflows of processing per second is about 4 square metres, approximately 1 ton/hour of water consumption.
