Description

The far infrared coal combustion and gasification environmentally-friendly boiler
Technical field:
The utility model relates to a kind of far infrared coal combustion and gasification environmentally-friendly boiler, belongs to the design and the manufacturing of environment-protection boiler, for productive life provides power and heating power.
Background technology:
The utility model patent 03217826.3 " coal combustion and gasification environmentally-friendly boiler " of authorizing in 2004, travel(l)ing grate is arranged at the body of heater bottom, and fire grate top is burner hearth, and upper furnace has some fire tubes, and the collection smoke box is arranged at fire tube top, and collection smoke box upper end has chimney to stretch out outside the boiler body.The burner hearth middle part has dividing plate that burner hearth is divided into vaporizer and combustion chamber, and the fuel gas that vaporizer produces enters the combustion chamber by gas piping, and the high-temperature flue gas that the combustion chamber produces enters the collection smoke box by fire tube.The shortcoming of this boiler is that the heating surface area of fire tube is little, increases boiler output and is limited to, and lacks secondary wind in combustion heat-exchange and flue gas flow, and the boiler surfaces radiation loss is big.
Summary of the invention:
The purpose of this utility model provides a kind of far infrared coal combustion and gasification environmentally-friendly boiler.It keep former utility model with coal-fired gasification after advantage such as burning again, the fire tube of top, combustion chamber is changed into several collection cigarette clean rooms, arrange some convection tubes respectively in collection cigarette clean room and combustion chamber, and far infrared burning radiation device, baffle plate and guard are set, increase overfiren air port, tertiary air orifice, make combustible and dust in the flue gas carry out the multistage combustion purification, reduce the body of heater radiation loss, further improve the environmental protection and energy saving effect.
The purpose of this utility model realizes as follows: the bottom of this far infrared coal combustion and gasification environmentally-friendly boiler is a travel(l)ing grate, burner hearth is arranged at fire grate top, burner hearth inside has dividing plate that burner hearth is divided into vaporizer and combustion chamber, and the lower partition has sideboard to regulate coal seam thickness.Vaporizer one side has coal feed point, and there is coal bunker in the coal feed point outside, and there are some convection tubes and far infrared guard in the middle part, combustion chamber.There are next part cigarette clean room and last collection cigarette clean room in the burner hearth top, the indoor convection tube that is provided with respectively, the outdoor super heat-conductive pipe that is provided with respectively on every side.There are far infrared guard, baffle plate and overfiren air port in next part cigarette clean room middle part, on collect bottom, cigarette clean room far infrared burner and tertiary air orifice arranged.
Coal produces coal gas under the suitable condition of vaporizer, coal gas enters the combustion chamber by gas piping, coal after the gasification promptly becomes coke, and along with the rotation of fire grate also enters the combustion chamber, coke and the coal gas red-hot in the combustion chamber burn jointly, carry out complex physico-chemical, because coal gas passes red-hot coke, carbon black and the basic after-flame of other combustible have been eliminated black smoke, purify flue gas, be called first class purification.When high-temperature flue gas entered next part cigarette clean room, far infrared guard and baffle plate changed the flue gas ascent direction, add that the free air space of clean room strengthens suddenly, and flue gas flow rate is corresponding to be slowed down, and formed the eddy current rotation, and dust granule sinks, and flue gas is finished secondary purification.Flue gas rises to collection cigarette clean room, and contained a small amount of combustible discharges stronger radiant heat on the one hand by the porous type far infrared burner after-flame that burns away, and has purified flue gas on the other hand once more, and three grades of purifications are finished.
One end of gas piping is connected with vaporizer top, by the boiler internal heat radiation, the other end is connected in the enclosed cavity of fire grate bottom through cigarette wind blender, and pipeline one side has bypass line and switch, discharges a small amount of flue gas when pressing stove.Used coal will contain an amount of moisture content.
Fire grate is placed on the furnace grate support, the transmission device that fire grate is rotated is connected with furnace grate support power, power set can be that motor adds gearbox designs, also can be that electromagnet passes through pull bar, reciprocating motion become rotatablely move, can also be other structure, as long as make the fire grate slow rotation.
Porous type far infrared burner and far infrared guard, baffle plate will have certain thermal shock resistance and higher radiation intensity, and enough flue gas circulation areas also will be arranged.
One end of super heat-conductive pipe absorbs heat in collection cigarette clean room, and the other end dispels the heat in water.The shell inwall is arranged some to magnetizer minimizing scale hazard.Boiler surfaces is set up heat-insulation layer, reduces radiation loss.
During work, fire coal enters vaporizer from coal bunker and produces coal gas, and the coal behind the generation coal gas becomes coke, sends the combustion chamber smokeless combustion to by the fire grate that rotates, and the slag of after-flame is discharged from slag notch; Coal gas is sent into the fire grate bottom by gas piping by cigarette wind blender, pass red-hot coal seam and enter the combustion chamber, at combustion chamber solid combustible and the basic after-flame of the common burning of gas combustible, a little combustible and flying dust enter collection cigarette clean room with high-temperature flue gas and carry out secondary again, three burnings and purification, far infrared device helps catalysis, realizes the utilization of coal clean and effective, need not to install smoke abatement and dust control and coal saving device, can reach the environmental protection and energy saving purpose.
Advantage of the present utility model: multiple new and high technology organically combines, and realizes the utilization of coal clean and effective, and inner digestion such as flue dust, combustible purifies, it is colourless dustless to discharge fume, and reduces greenhouse gas emission, and environment protecting is good, non-secondary pollution does not have two investments, and heating surface area is big, reduces exhaust gas heat loss's radiation loss of becoming estranged, improve thermal efficiency energy savings, lower than oil-burning gas-fired boiler and anthracite-fired boiler cost, be convenient to management, increase income and economize on spending, safety economy, the automatic and mechanical operation is carried out production strictly in line with rules and regulations.
