Description

Technical Field

[0001] The utility model relates to the technical field of garbage power generation, in particular to a filter screen used for improving the treatment efficiency of waste gas from garbage incineration. Background Art

[0002] With the improvement of people's living standards, the number of daily necessities has gradually increased, which has also led to an increase in domestic waste. The treatment of domestic waste is now a difficult problem. Using garbage to generate electricity can not only reduce garbage stacking, eliminate the spread of bacteria and infectious diseases, and reduce air pollution, but also obtain a certain amount of electricity from it. The principles of garbage disposal are harmlessness, reduction, and resource utilization. Garbage incineration power generation greatly reduces landfill and can save a lot of land resources. It also reduces the atmospheric pollution of groundwater and the surrounding environment of the landfill. When carrying out garbage incineration power generation, smoke and exhaust gas will be generated. At present, filter elements or filter screens are mostly used to filter the exhaust gas to remove larger particles in the gas. However, after long-term use, more debris will adhere to the filter element or filter screen, causing blockage, affecting the efficiency of flue gas treatment. More seriously, it will also cause flue gas blockage, causing the gas pressure in the combustion furnace to increase. Based on this, the present application proposes a filter screen for improving the efficiency of waste incineration waste gas treatment to solve the above problems. Utility Model Content
