Abstract
The utility model provides an anti-explosion device of a biomass gas filter, which comprises a filter shell. A gas inlet is arranged below the filter shell, a gas outlet is arranged at the top end of the filter shell, the bottom part of the filter shell is water-sealed in a water-sealing tank, and an overpressure safety valve is arranged on the gas outlet. At lest one through hole is arranged on the filter shell, and an asbestos plate is filled in the through hole in a sealing manner; three through holes are arranged on the filter shell, and the thickness of the asbestos plate is within 2 to 3mm. With the advantages of adopting simple structure, mitigating the explosion power of the filter and the like, the utility model improves the present anti-explosion device of the biomass gas filter and is suitable for industrial production.
Description
Technical field
The utility model relates to a kind of explosion-protection equipment, especially a kind of biomass fuel air filter explosion-protection equipment.
Background technology
In agricultural production, crops produce a large amount of discarded objects, except that stalk, also have rice husk, bagasse, wood chip, walnut shell, peanut shell, corncob, bark, wood shavings etc., these solid waste are referred to as living beings, the often abandoned of these living beings, burning, so not only waste energy, and severe contamination air ambient.Meanwhile, China also has some rural areas, small towns to lack cooking, heating fuel, some area in addition by cut down little tree, shrub is a fuel, has also seriously destroyed ecological environment, converting living beings to imflammable gas is the direction that solves this contradiction, and biomass gasifying furnace arises at the historic moment.
Filter in the prior biological matter gasification furnace has certain gas storage function, in the process of gas storage, danger with blast, existing technology is that the overpressure safety valve door is set on the gas outlet of filter, and being provided with a plurality of openings, the bottom place tank to seal, on the one hand because the overpressure safety valve door is long service time, the overpressure safety valve door lost efficacy, on the other hand because being deposited at the bottom of the filter after impurity tar filters in the gas that produces in the biomass gasifying furnace, the opening of bottom is stopped up, form sealing state, above-mentioned two kinds of situations combine, to cause the filter internal gas pressure to raise, produce explosion accident.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art and a kind of simple in structure, the biomass fuel air filter explosion-protection equipment that can alleviate the filter brisance is provided.
The purpose of this utility model is achieved by following technical proposals:
A kind of biomass fuel air filter explosion-protection equipment, comprise filter housing, described filter housing below is provided with air inlet, the top is provided with the gas outlet, the bottom is placed on water seal in the flashback tank, described gas outlet is provided with the overpressure safety valve door, offers at least one through hole on the described filter housing, and sealing is filled with asbestos board in the described through hole.
As a kind of improvement of the present utility model, offer three through holes on the described filter housing.
In the utility model, described asbestos thickness of slab 2mm-3mm.
Owing to adopt above-mentioned scheme, the utility model biomass fuel air filter explosion-protection equipment is provided with a plurality of through holes on filter housing, sealing is provided with asbestos board in the through hole, utilize the intensity of asbestos board to be lower than filter housing, make that explosion time is washed asbestos board open when filter generation fault internal pressure is excessive, alleviates brisance, thereby do not damage filter housing, do not cause casualties.
In sum, that described utility model biomass fuel air filter explosion-protection equipment has is simple in structure, can alleviate advantage such as filter brisance, is to a kind of improvement of existing biomass fuel air filter explosion-protection equipment, is suitable for industrial production.
