Description
Technical Field
The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device of a sludge drying storage yard.
Background
Along with the increase of national economy and the promotion of urbanization, municipal sludge and industrial sludge are increased year by year, so that the reduction, the harmlessness, the stabilization and the resource of the municipal sludge and the industrial sludge are realized. The sludge heat drying incineration treatment is a large-scale, thorough and efficient treatment form, is widely popularized and applied in the comprehensive energy synergistic utilization in recent years, but waste gas is generated in the sludge transfer process, and secondary pollution is easily caused.
The common anticorrosion method is to extract negative pressure and send the negative pressure into a hearth for incineration. However, large yards have not had a complete method of disposal.
In the sludge drying process, industrial sludge in factories such as municipal sludge and tanning of a sludge treatment plant is remotely transported to a wet sludge warehouse of the sludge treatment factory through a fully-sealed truck, the wet sludge is transported to a drying workshop through a fully-sealed scraper, moisture removed from the dried sludge is transported to a storage yard through a scraper, and the dried sludge is mixed with coal and then is sent to a hearth for incineration through a coal conveying belt. In the process of sludge transfer, the transfer space of a truck, a scraper and a belt is narrow, so that the transfer amount is smallSo as to avoid the overflow of waste gas. However, in wet sludge storage and storage yard, a large amount of sludge is accumulated and the space is large, and exhaust gas is easily generated. Some organic gases and microorganisms can escape and disperse metabolites in the environment, so that secondary pollution is caused. Predominantly NH3、H2S, mercaptan and thioether can emit foul smell, wherein NH is3、H2The highest S content. The harmful gas enters the respiratory tract to cause the mucous membrane of the human body, and the extremely high concentration gas can even cause diseases such as pulmonary edema, laryngeal edema and the like. There is a need for an effective closed treatment of the full life cycle of sludge drying.
The space in the wet sludge reservoir is smaller than that in a storage yard, and the generated waste gas can be introduced into a hearth through negative pressure and treated by a catalytic incineration method. The space of the storage yard is large, and if the storage yard is sent into a hearth for incineration, the volume is large, and primary air and secondary air of the unit are difficult to eliminate. In addition, the sludge in the storage yard is dried, a part of latent heat of vaporization is sealed in the sludge, the waste gas is easy to diffuse, and the fog is easy to generate. Meanwhile, due to the existence of latent heat of vaporization, when the steam meets the wall surface and the like, the steam is easy to condense to generate condensed water and has corrosiveness, so that the steam is not suitable for being sent out of a hearth to be treated in a long distance. Therefore, the waste gas of the storage yard needs a one-step pretreatment process to release latent heat in the sludge waste gas, so that the generated condensed water is prevented from corroding equipment and overflowing through a pipeline connecting joint. Furthermore, NH3、H2S, mercaptan and thioether substances are easily dissolved in water, and the waste gas treatment device of the sludge drying yard is invented based on the S, mercaptan and thioether substances.
