Abstract
The utility model relates to biomass gasification equipment which comprises more than one gasifier. The gas outlets of the gasifiers are connected in parallel by pipelines and provided with valves. The gasification equipment provided by the utility model overcomes the following defects of updraught and downdraught gasification equipment: during the operating, the sealing screw feeder of the updraught gasification equipment is often stuck by biomass material and needs to be dismantled and overhauled; the downdraught gasification equipment operates under micro negative pressure and needs an airtight ash outlet device, so the outlet of an ash outlet cage needs to be put into water to achieve the airtight effect; however, the problem that slag and carbon residue block the ash outlet cage under the effect of water also can happen, so the downdraught gasification equipment also has to be stopped and overhauled. The utility model provides the biomass continuous gasification equipment which has simple structure and reliable and convenient operation.
Description
Technical field
The present invention relates to the biomass energy equipment technical field, particularly a kind of biomass gasification device.
Background technology
At present, utilizing living beings to produce the method for fuel gas and device thereof on the market, to mainly contain updraft type, downdraft, fluidized bed type etc. several.Wherein the structure of fluidized gasification device, operation control and detection means be than updraft type, downdraft complexity, for going into stove grain graininess requirement thin (generally requiring) less than 0.4mm, and the investment threshold height, be difficult to extensive popularization in China; Though updraft type gas, downdraft gasification installation are simple in structure, easy to operate, but there are many weak points in operation continuously: because biomass material contains certain moisture content, has toughness, and material size is not of uniform size, biomass material jam phenomenon often occurs when therefore the sealing screw charger of updraft type gasification installation moves, usually need field-strip; The downdraft gasification installation is owing to be little negative pressure operation; require the ash discharging gear of sealing, the outlet of ash discharge flood dragon cage is placed water, though play sealing function; but lime-ash, carbon residue stop up the flood dragon cage under the effect of water problem also can occur, therefore also usually need to shut down maintenance.
Summary of the invention
The object of the invention is exactly at the problems referred to above, and the deficiency that overcome updraft type, has when the downdraft gasification installation moves continuously provides a kind of simple in structure, reliable, easy to operate living beings continuous gasification device.
Technical solution of the present invention is as follows: a kind of biomass gasification device, comprise the gas outlet of an above gasification furnace, described gasification furnace, and the gas outlet of described gasification furnace is connected in parallel with pipeline, and the gas outlet of described gasification furnace is provided with valve.
Described gasification furnace is downdraft or updraft type gasification furnace.
Described valve is high temperature resistant gas valve.
The beneficial effect that the present invention compared with prior art has is:
Each gasification furnace parallel with one another does not need continuous operation, does not just need complicated reinforced ash discharging gear, the alternately intermittent duty of gasification furnace one stove one stove in parallel yet.The present invention has realized reliable, easy to operate living beings continuous gasification by simple and practical structure.
Description of drawings
Fig. 1 is the structural representation of gasification installation of the present invention.
Combustion gas trunk line as shown in the figure, 1, gasification furnace, 2, the gas outlet valve, 3, gasification furnace, 4, the gas outlet valve, 5, gasification furnace, 6, the gas outlet valve, 7, the combustion gas branch pipe(tube), 8.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in detail.
As shown in Figure 1, gasification installation of the present invention is made up of gasification furnace 1, gas outlet valve 2, gasification furnace 3, gas outlet valve 4, gasification furnace 5, gas outlet valve 6, combustion gas branch pipe(tube) 7, combustion gas trunk line 8 etc.With biomass material pack into gasification furnace 1, gasification furnace 3, gasification furnace 5, open gas outlet valve 2, close gas outlet valve 4,6, operation gasification furnace 1, when gasification furnace 1 material reaction when finishing, close gas outlet valve 2, ash discharge is reinforced; Open gas outlet valve 4 simultaneously, operation gasification furnace 3 when the approaching end of gasification furnace 3 material reactions, is closed gas outlet valve 4, and ash discharge is reinforced; Open gas outlet valve 6 simultaneously, operation gasification furnace 5.The combustion gas that each gasification furnace produces is carried to combustion gas trunk line 8 via each combustion gas branch pipe(tube) 7, and so alternate run is realized continuous aerogenesis.
Among the present invention in parallel gasification furnace minimum be two, be more reliable and more stable, the easy access of operation, can also the gasification furnace more than two in parallel, gasification furnace can be selected downdraft or updraft type gasification furnace, valve can be selected high temperature resistant gas valve.
