The filter disclosed by the utility model is suitable for high-temperature dust removal, realizes a good filtering effect, and has a simple structure and a quick disassembly function.
Description
Technical field
The utility model relates to a kind of filter, specifically relates to the filter of impurity ash content in the combustion gas of a kind of depth-type filtration biomass high-temperature.
Background technology
High speed development along with Chinese Industrialization, urbanization, fossil energy shortage, increasing environmental pollution, reduction of greenhouse gas discharge pressure and forest and agricultural biomass utilization rate are low, restriction to China's national economy sustainable and healthy development manifests gradually, greatly develops to take clean energy resource that biomass fuel is representative and become national strategy and select.Biomass molding fuel is a kind of important biomass energy.It is formed by agriculture and forestry organic waste material extruding such as loose stalk, branch and wood chips, its energy resource density is equivalent to middle matter bituminous coal, and firepower is lasting, has good burning performance, be energy conversion efficiency the highest utilize mode, can be used as the industrial fuels such as family's life fuel and power plant's generating, kiln.
The ash impurities of biomass molding fuel itself is more, and the biological fuel gas that biomass combustion furnace prepares all contains a large amount of flying dusts, thin charcoal particle and tar.In order to reduce corrosion and the obstruction to pipeline of combustible gas neutral and alkali dust to upstream device (heat exchange boiler, generator), under low energy consumption, realize the high-efficient purification of combustible gas, must under hot conditions, directly carry out dust removal and filtration.
Cloth envelop collector is modal filter plant, and reason is its low cost of manufacture.But the problem that existing cloth envelop collector exists is: because biological mass combustable gas temperature is high, easily cause cloth bag life cycle to decline, meanwhile, biological mass combustable gas dustiness is higher, makes filter loading overweight, magnetic valve winding-up number of times increases, be unfavorable for saving energy and reduce the cost, more crucial, the filtering holes of cloth bag is larger, be difficult to small ash impurities to be filtered, make the filter effect of filter undesirable.
Utility model content
the technical problem solving:the utility model provides a kind of applicable high-temperature dust removal, good filtration effect, simple in structure and have a filter of quick-detachment function.
technical scheme:biomass high-temperature combustion gas dust removal filter, comprise cyclone separator and porous media filter, the top of described cyclone separator is provided with air inlet, bottom is provided with the first ash collection slot, porous media filter is provided with air inlet, exhaust outlet, rotary handle and the second ash collection slot, described air inlet is connected with the inner chamber of cyclone separator by wireway, and the second ash collection slot is located at the bottom of porous media filter, and rotary handle is located at the top of porous media filter.
In the cavity of described cyclone separator, be provided with refractory cement liner.
In described porous media filter, be provided with the coaxial detachable filtration screen group arranging, screen connecting axle is connected with rotary handle.
beneficial effect:the utility model is due to cyclonic separation and porous media double-filtration unit being set, when high-temperature biomass combustible gas is through cyclone separator, 99% lime-ash is separated to get off, porous media filter is passed through in combustion gas subsequently, dust residual in air-flow clashes into porous media screen and is blocked, and clean high-temperature combustible gas body passes through.The cyclone separator of liner refractory cement, can prevent that dust granule in high-temperature fuel gas from clashing into the damage that inwall causes cyclone separator, extension device service life.In addition, porous media filter is set and can removes lime-ash residual in combustion gas, screen is vertically set in porous media filter, can reach two objects: in (1) combustion gas, lime-ash shock porous media hole wall is blocked, and clean combustion gas is passed through; (2) under lime-ash high temperature, melting flows downward and enters ash collection slot, can not be deposited on screen, and blocking filter duct, guarantees that filter can long-time steady operation.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further set forth the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
embodiment 1:
Biomass high-temperature combustion gas dust removal filter, comprise cyclone separator 9 and porous media filter 6, the top of described cyclone separator is provided with air inlet 1, bottom is provided with the first ash collection slot 4, porous media filter is provided with air inlet, exhaust outlet 7, rotary handle 8 and the second ash collection slot 5, described air inlet is connected with the inner chamber of cyclone separator by wireway 3, and the second ash collection slot is located at the bottom of porous media filter, and rotary handle is located at the top of porous media filter.In the cavity of described cyclone separator, be provided with refractory cement liner 2.In porous media filter, be provided with 10 groups of the coaxial detachable filtration screens arranging, screen connecting axle 11 is connected with rotary handle 8.Inside establish and filter screen and can pass through rotary handle, according to how many adjusting screen angles of ash content in combustion gas, fully filter lime-ash.
The operation principle of porous media filter is: the high-temperature biomass combustible gas containing ash impurities is transported in cyclone separator 9 from air inlet 1, by cyclonic separation, going out 99% ash impurities enters in the first ash collection slot 4, combustible gas containing 1% left and right ash content enters in porous media filter 6 by wireway 3, by filtering after the collision of screen 10 with silicon carbide material, in air-flow, residual a small amount of lime-ash collision porous media filter is blocked and enters in the second ash collection slot 5, through exhaust outlet 7, discharges.This process is swept without blowback.
When porous media filter is shut down; for residual biomass combustible gas is drained; and make ceramic element protection clean (plate that prevents tar goes out to stop up ceramic element); need pass into hot nitrogen and not drain combustible gas and replace: stop inputting after biological mass combustable gas; starting heat air job contract does and input hot nitrogen in cylindrical shell; hot nitrogen continues to participate in not draining the filtration of biological mass combustable gas, until the complete expelling tube of residual biomass combustible gas is external.
