Comprehensive treatment system capable of realizing stage filtering for kitchen lampblack

Abstract

The invention provides a comprehensive treatment system capable of realizing stage filtering for kitchen lampblack. The comprehensive treatment system capable of realizing the stage filtering for thekitchen lampblack is used for a residential district, and comprises a fan, a primary separation device, a secondary separation device and a gas filtering device which are sequentially arranged, wherein the fan is used for conveying the kitchen lampblack to the primary separation device; the primary separation device is used for separating oil drops in the kitchen lampblack to obtain a primary separated substance; the secondary separation device is used for separating oil mist in the primary separated substance to obtain a secondary separated substance; and a gas separation device is used for removing impurities and peculiar smell of the secondary separated substance to obtain a tertiary separated substance. The comprehensive treatment system capable of realizing the stage filtering furthercomprises a spray device, wherein the spray device is arranged at the top of the gas filtering device. The comprehensive treatment system capable of realizing the stage filtering is capable of realizing that the kitchen lampblack is treated to achieve the national gas emission standards; and the separated dirty oil can be concentratedly conveyed to a dirty oil plant to be treated, the generated sewage can be concentratedly conveyed to a sewage plant to be treated, and concentrated collection for the dirty oil and the sewage is realized separately, and pollution is reduced.

Description

technical field [0001] The invention belongs to the field of environmental protection systems in residential quarters, and in particular relates to a comprehensive treatment system for kitchen oil fumes classified and filtered. Background technique [0002] As we all know, residents in residential areas and merchants in front door houses often produce a lot of oily fumes during food processing and cooking. These oily fumes contain oily dirt and toxic gases. If they are not handled properly, they will definitely pollute the air. But now, there is no mature treatment method in China. The usual method is to directly take the lampblack generated by households or merchants to the outdoors with range hoods, or use pipelines to directly transport them to the sewer, which will inevitably cause air or water pollution. [0003] At present, existing patents have proposed some solutions. For example, the patent with publication number CN107715644A proposes a system for harmless treatmen...

Problems solved by technology

But now, there is no mature treatment method in China. The usual method is to take the lampblack generated by households or businesses directly to the outdoors with a range hood, or use pipelines to directly transport it to the sewer, which will inevitably cause air or water pollution.

[0003] At present, existing patents have proposed some solutions. For example, the patent with publication number CN107715644A proposes a system for harmless treatment of oil fume, including a pretreatment module, a photolysis module and a filter module, which can realize the harmless treatment of oil fume. , but the waste liquid is directly discharged into the pipeline, which will cause certain pollution, and it is used for individuals such as restaurants, hotels, and families of various sizes; the patent with the publication number CN105115010A proposes a baffle type electrostatic oil fume purification device and its use method. Including oil drop filtration system, electrostatic system and deodorization system, it can realize the graded treatment of oil fume, but it is mainly used for a certain family, and cannot achieve comprehensive treatment of oil fume in the whole community; the patent publication number is CN102908853A proposes an indoor oil fume flying machine. Dust purification equipment can realize the treatment of indoor oil fumes and flying dust, but there are also limitations in use; the patent publication number is CN107023868A proposes a residential kitchen oil fume concentration and harmless plasma treatment equipment, which can also realize the harmless treatment of oil fumes Chemical treatment, but it needs to use electric tar capture, plasma dielectric barrier device, etc. The use of more electric devices leads to low reliability and safety of the entire equipment, and it is mainly used in family and residential kitchens.

[0004] To sum up, the existing patents are mainly aimed at the treatment of oil fumes in individual households, and there is no report on the comprehensive and harmless treatment of oil fumes in the entire residential area.
