Aerobic composting waste gas filtering equipment and method

Abstract

The invention relates to the technical field of waste gas filtration, in particular to aerobic composting waste gas filtration equipment and method. The aerobic composting waste gas filtration equipment comprises a filtration module, a placement module is arranged on one side of the filtration module, the filtration module comprises a shell, the bottom of the side face of the shell communicates with a gas inlet pipe, and the top of the side face of the shell communicates with an exhaust pipe; three filtering frames are slidably connected to the side face of the shell at equal intervals, filtering elements are arranged in the filtering frames, and two clamping rods are fixedly connected to the positions, corresponding to the three filtering frames, of the two side faces of the shell correspondingly. The side surface of the placing frame is in sliding connection with the clamping rod, so that a new filter element can be placed in an additional matched filter frame, then the new filter frame extrudes an old filter frame from one side, and the old filter frame is extruded into the placing frame, so that the new filter element is replaced, and the replacement of the filter element is relatively simple; the filtering equipment does not need to be stopped, and the replacement efficiency is improved and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of waste gas filtration, in particular to an aerobic composting waste gas filtration device and method. Background technique [0002] Organic fertilizer is the main nutrient source of 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 waste. Microbes, through their own life activities, synthesize part of the organic matter into new cytoplasm, and oxidize the other part of the organic matter into Simple inorganic substances such as H2O and CO2, and the fermentation process will produce a certain amount of waste gas such as H2S and NH3 due to the existence of anaerobic. Therefore, in order to avoid secondary pollution in the aerobic composting process, it is necessary to use it during aerobic compos...

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
