Abstract
The invention relates to a sealing device for a biomass gasification furnace. In the sealing device, a seal groove (2) is formed on the top of the biomass gasification furnace; the seal groove (2) is communicated with a blast blower (4) through an air inlet pipe (3); when a furnace cover (5) covers the furnace, an air inlet (6) of the air inlet pipe (3) is positioned on a furnace cover outer edge (7); and an air inlet channel (9) is reserved between an inner ring (8) of the seal groove (2) and the top part of the furnace cover (5). The sealing device adopts pressurized seal, without using water, so the sealing device has the advantages of convenient operation, no tar odor and capacity of reducing emission of the tar and increasing gas-making time.
Description
Technical field
The present invention relates to the biomass gas-making furnace tool, specifically, provide a kind of tightness system of biomass gasifying furnace.
Background technology
Biological fuel gas be utilize plant fuel by producer under airtight relative anoxia condition, adopt a kind of inflammable gas that produces after dry distillation pyrolysis and the thermochemistry oxidation style.Though the research of biomass household gasification furnace is a lot, a lot of biomass household gasification furnace products have also appearred on the market, all are difficult to extensively be promoted, one of them major reason is that the biomass coke tar that is produced in the combustion gas is difficult to remove.Chinese patent disclosed a kind of " integrated composite gasification furnace " (200910043224.X) preferably resolves the biomass coke tar problem.But, the sealing that prior biological matter producer generally adopts gasket to tighten with bolt, troublesome poeration not only, and can not seal fully.Because in use the tar in the combustion gas can cling a lot of dusts and impurity after sticking on gasket, along with the lengthening of duration of service, gasket can form and be uneven and leak gas, leak tar, causes body of heater and environmental pollution.Above-mentioned patent has adopted the structure of water-lute, and good sealing effect, speed are fast.But the greatest drawback of water-lute be the water capacity easily by tar pollution, use for some time after, the water in the water sealed tank almost is water and tar half-and-half, and denseer smell is not only arranged, and pollutes body of heater and environment.
Summary of the invention
The object of the present invention is to provide a kind of water sealing device of biomass gasifying furnace, it adopts pressurized seal, does not need water, and is easy to operate, and no tar smell can reduce the tar discharging, and can increase the gas making time.
For achieving the above object, embodiment of the present invention are:
A kind of tightness system of biomass gasifying furnace is characterized in that, at furnace roof sealing groove is set, sealing groove is communicated with gas blower by blast pipe, when bell covered, the blast inlet of blast pipe was positioned at the bell outer, left air intake passage between the interior ring of sealing groove and the bell top.
What optimize is, is provided with ring washer in the described sealing groove, and ring washer has air-inlet cavity between bottom sealing groove, and air-inlet cavity communicates with blast pipe, and intake opening is arranged on the ring washer.
Perhaps, ring washer is set in sealed cistern, leaves the air intake space between the interior ring of ring washer and sealing groove.
What more optimize is that ring washer has upwardly extending inside edge, leaves the air intake space between the interior ring of inside edge and sealing groove.
The blast pipe that communicates with sealed cistern and the air-supply duct that enters furnace bottom and the oxygen Guan Yuyi gas blower of joining that enters stove are communicated with.
What the present invention adopted is a kind of hermetic seal method, the scientific basis of hermetic seal is to adopt the air of powered compressor (comprising the mini fan that vapourizing furnace uses) to form vapour lock in sealing cover, during less than vapour lock pressure, just can realize hermetic seal at gaseous-pressure, its advantage shows the following aspects:
(1) operating aspect, speed is fast.During sealing, just finished seal operation as long as sealing cover put, the time only needed for 1 second;
(2) no tar smell.Charging opening and feeding cover not only do not have tar pollution, and do not have any smell;
(3) the gas making time is long.Because the vapour lock of hermetic seal is greater than gaseous-pressure, after the combustion gas of top of gasification furnace and air formed and liquidate, it was the major cause of growing the gas making time that the airflow slows it of vapourizing furnace bottom oxidization layer and reducing zone, responding layer are moved on not;
(4) reduce tar content.Because top of gasification furnace (charging opening) has freezing air to enter, tar and moisture content are separated in rapidly realize in the raw material that secondary combustion transforms, and can in the combustion gas course of conveying, carry out primary combustion;
(5) do not increase cost.Once the cover vapourizing furnace only need a mini fan to finish air intake the time spent, join oxygen, the entire work process of hermetic seal.
