Description
Technical field
The utility model relates to a kind of boiler, specifically a kind of biomass boiler.
Background technology
At present, the boiler of biomass granule fuel is utilized mostly to be chain furnace, Circulation fluidized-bed furnace and minitype vertical type fire tube boiler, wherein chain furnace heat loss is large, the thermal efficiency is low, and Circulation fluidized-bed furnace complex structure, volume are large, usually larger space is taken, and installing engineering amount is large, vertical fire-pipe stove is then mainly used in small steam and hot-water boiler, and relevance grade is narrower; In addition, above-mentioned boiler in combustion, many meetings bring dust lime-ash into boiler internal with flue gas, and pile up at stove tail, in the course of time by directly cause inner flue gas of the stove flow smooth, burner combustion deleterious, fuel combustion not thoroughly, burner fire-resistant parts damage rapidly because smouldering, dust stratification serious, heat transfer effect is deteriorated, boiler output obviously descends degradation problems because cigarette speed is slack-off for smoke pipe, and boiler Overall energy efficiency is reduced greatly.
Utility model content
The purpose of this utility model is to provide a kind of biomass boiler, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of biomass boiler, comprise biomass burner, horizontal tubular boiler body and boiler water inlet pipe assembly, described biomass burner is connected with horizontal tubular boiler body, is provided with flue in horizontal tubular boiler body, is provided with two return smoke pipe and three backhaul smoke pipes in flue; Horizontal tubular boiler body afterbody is provided with exhaust opening; Cinder-discharging port and ash-unloading door is provided with bottom the rear smoke box of described flue afterbody; Boiler water inlet pipe assembly is provided with above described flue, boiler water inlet pipe assembly comprises water tank, water-supply-pipe, pushing off the slag pipe, water pipe bubble, pushing off the slag pipe drainpipe and tank drains pipe, pushing off the slag pipe drainpipe connecting water pipe bubble, tank drains pipe connecting water pipe bubble, is also provided with a water knockout drum before tank inlet pipe, water knockout drum connects water-supply-pipe, water-supply-pipe before water knockout drum is provided with flow control valve, and the water-supply-pipe of flow control valve nose is communicated with pushing off the slag water inlet tube pipe by three-way piece.
Further, described horizontal tubular boiler body is refractory brick material.
Further, described two return smoke pipe and three backhaul smoke pipes are arranged in order from bottom to top.
Compared with prior art, the flow velocity that the utility model realizes each water inlet pipe regulates separately, control, each self-flow rate can be controlled flexibly according to pressure change, guarantee circulating of current in water tank and pushing off the slag pipe, compact conformation, take up room little, the more important thing is and effectively can avoid excessive dust stratification in boiler, reduce flue blockage probability, thus can heat transfer effect be ensured, strengthen boiler output, reduce rate of occurrence of equipment failure, also the service life of burner is extended from another point of view, in addition, structure of the present utility model directly can transform middle-size and small-size fuel oil multitubular boiler, it is made to use environmental protection regenerative resource, for enterprise's investment reduction cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of biomass boiler.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1, a kind of biomass boiler, comprise biomass burner 1, horizontal tubular boiler body 2 and boiler water inlet pipe assembly 5, described biomass burner 1 is connected with horizontal tubular boiler body 2, be provided with flue 21 in horizontal tubular boiler body 2, in flue 21, be provided with two return smoke pipe 22 and three backhaul smoke pipes 23; Horizontal tubular boiler body 2 afterbody is provided with exhaust opening 4; Biomass burner 1 firing biomass fuel, produce high temperature pyrotechnics and directly send in horizontal tubular boiler body 2 by crater, pyrotechnics enters after in flue 21, carries out heat exchange successively through two return smoke pipe 22, three backhaul smoke pipe 23, finally by exhaust opening 4 discharged to smoke processing system; When flue gas by the flue 21 with comparatively large cross-sectional area turn round enter the less two return smoke pipe 22 of bore restrain time, the major part of the dust lime-ash that flue gas is taken out of, particularly unburnt charcoal particle, will fall at this position, be piled up in flue 21 afterbody; For this reason, cinder-discharging port 31 and ash-unloading door 3 is provided with bottom the rear smoke box of described flue 21 afterbody; During normal use, cinder-discharging port 31 is closed by ash-unloading door 3, anti-leak-stopping cigarette, along with the accumulation of dust lime-ash, when dust lime-ash is abundant, opens ash-unloading door 3, the lime-ash of deposition in this position is cleared up in time; Boiler water inlet pipe assembly 5 is provided with above described flue 21, boiler water inlet pipe assembly 5 comprises water tank 51, water-supply-pipe 54, pushing off the slag pipe 56, water pipe bubble 57, pushing off the slag pipe drainpipe 58 and tank drains pipe 59, pushing off the slag pipe drainpipe 58 connecting water pipe bubble 57, tank drains pipe 59 connecting water pipe bubble 57, a water knockout drum 53 is also provided with before tank inlet pipe 52, water knockout drum 53 connects water-supply-pipe 54, water-supply-pipe 54 before water knockout drum 53 is provided with flow control valve, and the water-supply-pipe 54 of flow control valve nose is communicated with pushing off the slag water inlet tube pipe 55 by three-way piece; During use, water-supply-pipe 54 before water knockout drum 53 is provided with flow control valve, the water-supply-pipe 54 of flow control valve nose is communicated with pushing off the slag water inlet tube pipe 55 by three-way piece, realization is intake to water tank 51 and pushing off the slag pipe 56 is intake shunts, and be provided with flow control valve separately, the flow velocity realizing each water inlet pipe regulates separately, controls, and flexibly can control each self-flow rate according to pressure change, guarantees circulating of water tank 51 and current in pushing off the slag pipe 56; The utility model compact conformation, take up room little, the more important thing is and effectively can avoid excessive dust stratification in boiler, reduce flue blockage probability, thus heat transfer effect, enhancing boiler output, reduction rate of occurrence of equipment failure can be ensured, also extend the service life of burner from another point of view, in addition, structure of the present utility model directly can transform middle-size and small-size fuel oil multitubular boiler, making it use environmental protection regenerative resource, is enterprise's investment reduction cost.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
