A kind of aerobic composting waste gas filtering equipment and method

Abstract

The present invention relates to the technical field of waste gas filtration, in particular to an aerobic composting waste gas filtration equipment and method, including a filter module, a placement module is arranged on one side of the filter module, and the filter module includes a shell, and the bottom of the shell side is connected with a An air intake pipe, an exhaust pipe is connected to the top of the side of the housing, three filter frames are equidistantly slidably connected to the side of the housing, a filter element is arranged inside the filter frame, and the three filter frames corresponding to the two sides of the housing are all fixed There are two locking levers connected. In the present invention, the new filter element can be placed in the additional matching filter frame by slidingly connecting the side of the placement frame with the clamping rod, and then the new filter frame can be squeezed from one side to the old filter frame, and the old filter The filter frame is squeezed into the placement frame to replace a new filter element. It is relatively simple to replace the filter element and does not need to stop the filter equipment, which is beneficial to improve the replacement efficiency and is easy to use.

Description

technical field [0001] The invention relates to the technical field of waste gas filtration, in particular to an aerobic compost waste gas filtration device and method. Background technique [0002] Organic fertilizer is the main source of nutrients for high-quality organic green food. It can improve soil, improve fertility, increase crop yield, and improve crop quality. Aerobic composting is the main method of producing organic fertilizers. Under aerobic conditions, aerobic bacteria absorb, oxidize and decompose wastes, and microorganisms, through their own life activities, synthesize part of the organic matter into new cytoplasm, and oxidize the other part of the organic matter into new cytoplasm. Simple inorganic substances such as H2O and CO2, and at the same time, due to the existence of anaerobic fermentation, a certain amount of waste gas such as H2S and NH3 will also be generated. Therefore, in order to avoid secondary pollution in the aerobic composting process, it ...

AI Technical Summary

Problems solved by technology

[0003] When the existing filter equipment is in use, different filter elements need to be used to filter different types of exhaust gas. After the filter element has been used for a period of time, the filter element may be blocked by impurities in the exhaust gas, or the filter agent in the filter element will fail. , At this time, the filter element needs to be filtered, because the replacement of the filter element needs to stop the filter equipment, and the replacement of the filter element is more troublesome, so that the filter equipment needs to stop the filter equipment for a long time when replacing the filter element, which is inconvenient to use
