Problems solved by technology
In some inspection wells of drainage and sewage pipelines, there is usually accompanied by odor generation, which escapes from the well and pollutes the surrounding environment. pose a potential threat
Although the airtight manhole cover can be improved to temporarily solve this problem, but the concentration of the odor (main components include hydrogen sulfide, ammonia, etc.) in the inspection well is too high, and there is a danger of explosion in case of sparks. Therefore, most manhole covers will have ventilation holes , to reduce the concentration of dangerous gas in the inspection well, because the latter is more dangerous, although there are some schemes such as activated carbon to eliminate the odor, but it has short timeliness and troublesome operation

[0022] Implementation plan: such as figure 1 The filter device for sterilization and deodorization wells includes a funnel 8 placed in the inspection well and below the well cover 1. There is a gap between the funnel 8 and the well wall 2. A filter box 3 is arranged below the funnel 8, and placed in the filter box 3. There is a filter material 4, the bottom of the filter box 3 is provided with a hole 5, and a spoiler strip 6 is arranged below the bottom of the filter box 3. Still have space between funnel 8 and well wall 2, so that the air flow after filtering. Since the spoiler strip 6 is set under the bottom of the filter box 3, the polluted air in the well will not easily escape through the path of the funnel 8, reducing the emission of polluted gas; at the same time, the spoiler strip does not affect rainwater, etc. Flow through the funnel 8 to the bottom of the well.
[0023] Preferably, the filter material 4 is calcium chloride particles. Calcium chloride has the func...

The invention discloses a filtering device for sterilization and deodorization wells. The filtering device comprises a funnel arranged in an inspection well and located below a well lid, a gap is reserved between the funnel and the well wall, a filtering box is arranged below the funnel, a filtering material is placed in the filtering box, a hole is formed in the bottom of the filtering box, and aturbulent flow strip is arranged below the bottom of the filtering box.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a sterilizing and deodorizing device in an inspection well, which is installed in the inspection well. Background technique [0002] The inspection well is set up for urban underground pipeline engineering and is used for the maintenance of underground pipelines. In some inspection wells of drainage and sewage pipelines, there is usually accompanied by odor generation, which escapes from the well and pollutes the surrounding environment. pose a potential threat. Although the airtight manhole cover can be improved to temporarily solve this problem, but the concentration of the odor (main components include hydrogen sulfide, ammonia, etc.) in the inspection well is too high, and there is a danger of explosion in case of sparks. Therefore, most manhole covers will have ventilation holes , to reduce the concentration of dangerous gases in the inspection...
