Abstract
The utility model discloses a domestic bio-material gasifying furnace movable furnace bridge. When the bio-material combustion gasifying area is apart from the burner, the furnace bridge moves upwards under the action of the rack or screw by rocking the rocker connected on the gear, so that the bio-material combustion gasifying area is in a certain distance from the burner; and the effective gasification of bio-material fuel is ensured besides the efficient combustion of combustible gas. Obviously, the domestic bio-material gasifying furnace moveable furnace bridge of the utility model overcomes the deficiencies that the temperature of the burner in prior art is lowered, the temperature of the combustible gas transferred to the burner is lowered, and the heat of the combustible gas is not fully utilized.
Description
Technical field
The utility model relates to the movable grate of domestic biomass gasification stove, specially refers to the movable grate of the domestic biomass gasification stove that biomass combustion vaporizer and burner directly communicate.
Background technology
Domestic biomass gasification stove is to utilize living beings (as: agricultural waste material such as stalk, rice husk, branch, weeds or house refuse etc.) to burn under anaerobic condition, make most of combustible species be converted into fuel gas, through cooling, purify after for uses such as cooking, heatings.Common household gasification furnace comprises updraft type fixed-bed gasification furnace and downdraft fixed-bed gasification furnace.Updraft type fixed-bed gasification furnace basic structure is a cylindrical furnace, is lined with refractory material at inboard wall of furnace body, and the body of heater bottom is connected with air intake pipe, and upper of furnace body has the sealing loam cake.During use living beings are put into body of heater, the igniting airtight burning in back is only carried air by air blast in body of heater, and the control air input just can guarantee the anoxycausis of living beings, generates fuel gas.Top at body of heater is provided with the fuel gas gathering-device usually, and the pipeline of outside transporting combustible gases is arranged.
At present, household gasification furnace mostly is a split-type structural, be that gasification furnace separates with burner, after gasification furnace is collected the fuel gas of living beings gasification back formation, be transported to cooling device, filter or tar separation device etc. by pipeline, to remove dust in the fuel gas, tar etc., be transported to burner combustion again.And the most unmanageable in this course of conveying be exactly tar in the combustion gas, higher because of its content, in course of conveying, may be deposited in pipeline or cooling device and the filter, cause gas pipeline or device to block, form secondary pollution or the like.In addition,, then may cause fuel gases calorific value lower if tar separation is not thorough, can not effective use of energy sources, phenomenons such as burner collection charcoal obstruction.
Be to solve the problem of the collection of domestic biomass gasification stove fuel gas, purification and difficulty of transportation, occurred the domestic biomass gasification stove that biomass combustion vaporizer and burner directly communicate recently again.This gasification furnace directly communicates vaporizer with burner, and the fuel gas that the biomass combustion gasification produces does not need to collect, and is delivered directly to burner combustion.This mode does not need fuel gas is collected, purified and carries, and has overcome the shortcoming that split type biomass gasifying furnace exists.But, because this mode adopts combustion system from top to bottom, minimizing along with biomass fuel quantity in the combustion gasification process, the biomass combustion gasification zone is more and more far away from the distance of burner, make the temperature of burner decrease, the temperature that is transferred to the fuel gas of burner decreases, and the heat energy of gas fuel burning does not make full use of.
Summary of the invention
For solving the domestic biomass gasification stove above shortcomings that prior art biomass combustion vaporizer and burner directly communicate, the utility model proposes movable grate moving up and down, guarantee the gasification of gasification furnace biomass combustion fully, fuel gas fully burns, and heat energy is fully used.
The movable grate of the utility model domestic biomass gasification stove is placed in gasification furnace burner hearth center, and grate bottom centre is fixedly connected with straight-bar moving up and down, and a side of straight-bar is equipped with gear, but on the gear walking bar rod is housed.
The moved up and down straight-bar that the utility model domestic biomass gasification stove travelling oven pars basilaris pontis center fixation connects is a tooth bar, and the gear of straight-bar one side is a spur gear, and the engagement of commutating tooth wheel and rack is installed.
The moved up and down straight-bar that the utility model domestic biomass gasification stove travelling oven pars basilaris pontis center fixation connects is a screw rod, nut is housed on the screw rod, the nut outer is a helical gear, and the gear of straight-bar one side is a helical gear, and this helical gear and endoporus are that the helical gear engagement of nut is installed.
The movable grate of the utility model domestic biomass gasification stove in the biomass combustion gasification zone when the distance of burner is far away, be connected rocking bar on the gear by shaking, grate moves up under the effect of tooth bar or screw rod, make biomass combustion gasification zone and burner remain on suitable distance, both can guarantee effective gasification of biomass fuel, guarantee the abundant burning of fuel gas again.Obviously, the temperature that the movable grate of the utility model domestic biomass gasification stove has overcome the prior art burner decreases, and the temperature that is transferred to the fuel gas of burner decreases, the deficiency that the heat energy of gas fuel burning does not make full use of.
