Description

Deodorization inspection well cover

Technical Field

The utility model belongs to the technical field of well covers, and particularly relates to a deodorizing inspection well cover.

Background

Sewage pipelines, including rainwater pipelines, produce large amounts of sulfur-containing organic matters, represented by hydrogen sulfide, ammonia, mercaptans, sulfides and the like, due to the residual sewage and the existence of sediments, and these components are often products of wastewater or sediments in the pipelines under the action of anaerobic fermentation or anaerobic respiration of microorganisms, are slightly soluble in water or are extremely volatile, and can volatilize from the water into the air of a pipeline system; in addition, many volatile components such as fats, alcohols and ethers contained in the wastewater and chemical solvents are volatilized into a gaseous state and enter the upper space of the pipeline. Because of the poor ventilation in the pipeline, the concentration of the pollutant components in the air in the pipeline can reach high concentration, and the concentration of the hydrogen sulfide can even reach more than 1000mg/m < 3 >. Such contaminated air is discharged from manhole cover openings of a manhole (also called a manhole) of a piping system into the surrounding air, and affects the environmental quality of streets and living spaces around the manhole, and particularly in summer, the periphery of the manhole cover often has a strong unpleasant smell, and seriously affects the physical and mental health of people living around the manhole cover. In addition, many industrial and mining industries, particularly the chemical, pharmaceutical and light textile industries, contain significant amounts of volatile organic components in wastewater which is typically transported by gravity pipelines to wastewater treatment stations for treatment in the factory, and during the transportation of wastewater, volatile organic materials can spill from the water into the pipelines and spill into the external atmosphere at the manhole covers, affecting the air quality in the factory.

The polluted air formed in these pipes eventually enters the urban atmosphere. If not prevented and treated, the components become important pollution sources of the urban atmosphere environment, and the components not only have unpleasant smell, but also bring about urban haze, air pollution, photochemical pollution and urban atmosphere ozone concentration. The main countermeasure for preventing and controlling the overflow gas of the sewer is to adopt a deodorizing well cover. At present, many patent technologies are proposed for designing deodorizing manhole covers, and mainly adopt an isolation method, so that the holes on the manhole covers adopt a certain water seal design, rainwater on the manhole covers can flow into the manhole along the holes on the manhole covers in rainy days, and air in the manhole cannot flow into the atmosphere outside the manhole when the rainwater does not fall. Although this strategy can prevent odor from overflowing, the pollution components are only limited in the well, and once the inspection well cover is opened, the pollution components can be emitted into the air to pollute the environment. Some other patents, such as CN2755181Y, adopt a purification module, the purification module is directly installed and fixed under the manhole cover, the purification module adopts biological filtration or adsorption materials or oxidants, the method does not consider perfect rainwater and gas diversion, the rainwater can enter the purification module to cause the filtration materials to fail, and biological filtration is adopted, generally longer residence time is required, so that a larger volume is required, the effect is poor if the volume is too small, and the deodorizing purpose cannot be achieved. CN205917737U discloses a deodorizing well lid, the well lid is provided with a rainwater power generation device, the power generation device provides power for an LED lamp, the LED lamp irradiates a photocatalyst arranged below the well lid, and waste gas is purified when passing through a photocatalyst layer, but the power generation device cannot work when not raining, so that the deodorizing purpose cannot be realized when not raining.

Chemisorption (chemisorption) or dry scrubbing (dry scrubbing) has been used in the industry and civil fields for the purification of exhaust gases, both methods being essentially the same when using chemical filter materials, so chemical filter materials are also called dry chemisorption filter materials or simply dry chemical filter materials. Unlike the traditional adsorption materials such as active carbon and molecular sieve, the dry chemical filter material has the same strong adsorption performance and strong chemical reaction activity, and can adsorb and react the polluted components in the waste gas into harmless components, so that the used chemical adsorbent generally has no obvious environmental hazard, and the common chemical filter material is classified into different categories according to different components and reacts with the reducing components, the acidic components and the alkaline components in the waste gas respectively. For specific treatment objects, the dry chemical filter material has higher adsorption capacity than the traditional adsorption material, and meanwhile, the treatment device is simpler because no waste liquid is generated, so that the method is an economical and efficient waste gas purification method. At present, dry chemical filter materials are not used in the design and manufacture of deodorizing manhole covers.

In summary, many patent technologies have proposed the scheme of deodorizing the manhole cover, and the patent technologies mainly adopt an isolation method, so that the opening on the manhole cover adopts a certain water seal design, and the rainwater on the rainwater well cover can flow into the well along the air, and the air in the well cannot flow into the atmosphere outside the well when the rainwater is not falling. Although this strategy can prevent odor from overflowing, the pollution components are only limited in the well, but the manhole cover is opened, and the pollution components can be diffused into the air to pollute the environment. Some other patents adopt purification modules, mainly adopt biological filtration or photocatalysis disinfection and sterilization, the methods often can not well lead air and rainwater to be split, rainwater can enter a filter layer in rainy days, the performance of a filter material is influenced, and the biological filter material is adopted, so that a great space is often occupied to play a good role, and the purification effect is not ideal or the normal use of a well lid is influenced due to the fact that the large space is occupied. Therefore, better design of the deodorizing manhole cover is needed in practical application at present.
