Odor purification device

Abstract

The invention discloses an odor purification device, and belongs to the field of odor treatment. The device comprises a first box body, the bottom in the first box body is divided by a first partition plate to form an air inlet cavity, a second pump body is arranged outside the first box body and communicates with the air inlet cavity through a pipe body, and an air inlet pipe body is arranged on the upper portion of the first partition plate. The upper portion of the first box body is connected with a first exhaust pipe, the upper portion of the first partition plate is provided with a water washing layer, the air outlet end of the first exhaust pipe is bent, the air outlet of the first exhaust pipe faces the first partition plate, the first exhaust pipe is a square pipe, and the two opposite pipe walls of the air outlet of the first exhaust pipe are provided with inserting grooves corresponding in position. Exhaust plate groups are arranged in the inserting grooves. According to the device, the odor is collected and then treated in a centralized mode, the removal rate of the treated odor reaches 96% or above, the odor divergence rate is reduced, the dust content in the odor is reduced while the odor is treated through a water washing method, and the whole odor treatment process is low in noise, low in cost and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of waste odor treatment, and in particular relates to an odor purification device. Background technique [0002] The descriptions in this section merely provide background information related to the disclosure in this application and may not constitute prior art. [0003] The screening pretreatment of municipal solid waste is the first step in the recycling of urban waste, but a large amount of dust and odor are often emitted during the waste screening process, which seriously affects the surrounding environment and manual work, especially for waste disposal. The environment and air quality near the station or garbage collection point have a great impact, and the garbage will emit a large amount of malodorous substances represented by sulfur and nitrogen compounds during the long-term storage process, which is listed as the second only to noise pollution.

Problems solved by technology

[0003] The screening pretreatment of municipal solid waste is the first step in the recycling of urban waste, but a large amount of dust and odor are often emitted during the waste screening process, which seriously affects the surrounding environment and manual work, especially for waste disposal. The environment and air quality near the station or garbage collection point have a great impact, and the garbage will emit a large amount of malodorous substances represented by sulfur and nitrogen compounds during the long-term storage process, which is listed as the second only to noise pollution. The second major pollution, due to its relatively low olfactory threshold and scattered distribution, makes its treatment a recognized problem

[0004] The common method of odor treatment at existing garbage disposal stations or garbage collection points is to use fans to quickly blow off the odor to dilute it in the air. Although this method reduces the odor concentration at the garbage storage point, it does not To fundamentally solve the problem of odor, there are still existing methods of using chemical agents to deal with garbage odor, but the economic cost of using a large number of deodorizing chemicals or adsorbents is relatively large and the effect is general
