Garbage combustion fly ash filtering device based on local membrane separation

Abstract

The invention discloses a garbage combustion fly ash filtering device based on local membrane separation. The invention belongs to the technical field of garbage combustion. According to the garbage combustion fly ash filtering device, ammonium chloride powder in an air bag is heated and decomposed into hydrogen chloride gas and ammonia gas through high-temperature flue gas and continuously expands; an arc-shaped movable sheet is pushed to move upwards to extrude a hot melt adhesive solution out of a slow-release ball bag; under the action of microvilli at the outer ends of rubber thorns, theouter ends of the rubber thorns are covered with the hot melt adhesive liquid; barbs on an animal tongue and mucus on the surface of the animal tongue can be simulated through the rubber thorns and the hot melt adhesive liquid; particulate matters in the flue gas are adsorbed; after the temperature returns to the normal temperature, hydrogen chloride gas and ammonia gas react to generate an ammonium chloride solid and enable the air bag to shrink quickly, and under the action of pressure difference, particulate matters between an exhaust pipeline and an upper filter membrane are absorbed intothe slow-release ball bag and adsorbed by the adsorption layer and the hot melt adhesive on the surface of the adsorption layer, so that the smoke filtering effect is improved.

Description

technical field [0001] The invention relates to the technical field of waste combustion, and more specifically relates to a waste combustion fly ash filter device based on partial membrane separation. Background technique [0002] Garbage is a waste item that has lost its use value and cannot be used. It is an important link in the material cycle. It is an unnecessary or useless solid or fluid substance. In densely populated cities, garbage disposal is a headache. Common The method is to collect and send to landfill for landfill treatment, or to incinerate in an incinerator, but both will cause environmental protection problems, and ending excessive consumption can further reduce the saturation of landfills. Garbage disposal will not only pollute the groundwater and emit a bad smell, but also the area available for landfill in many cities has become less and less, and incineration will inevitably produce toxic gases, which are harmful to organisms. Most cities are studying t...

Problems solved by technology

[0004] At present, when incinerating garbage, it is necessary to treat the flue gas and fly ash generated during the incineration process, but in the prior art, the generated flue gas and ash are usually passed into the water to reduce the generated flue gas The possibility of polluting the air with ash flying, but it needs to waste a lot of water resources, which is not conducive to the sustainable development of environmental governance
