Embodiment 1

[0030] A treatment device for oily waste gas, such as figure 1 As shown, it includes a waste gas conduit 1, an induced draft fan 2, an oil removal chamber 3, a biological deodorization chamber 4, a heat distillation furnace burner 5, a filter device 6 and an exhaust cylinder 7 arranged in sequence, and the waste gas conduit 1 is a double layer Conduit, the inner layer is exhaust gas, the outer layer is a condensation pipe, the induced draft fan 2 is connected to the exhaust gas conduit 1, the side of the degreasing chamber 3 is connected to the exhaust gas conduit 1, and the top of the degreasing chamber 3 is provided with a dosing spray Shower pipe 8, the bottom of the degreasing chamber 3 is connected to the oil-water separation chamber 9, and the other side of the degreasing chamber 3 is connected to the biological deodorization chamber 4 through a pipeline; the biological deodorization chamber 4 is provided with a washing liquid spray pipe 15 and a biofilter 14, the biofil...

Embodiment 2

[0038] This embodiment provides a method for treating oily waste gas, using the oily waste gas treatment device provided in Example 1, including the following steps:

[0039] S1. After the oily waste gas is collected, it enters the waste gas conduit 1, and after condensation and cooling, the effect of subsequent treatment is improved;

[0040] S2. The exhaust gas is blown into the degreasing chamber 3 through the induced draft fan 2 for lye spraying, and the oil and water enter the oil-water separation chamber 9 through the inclined baffle in the degreasing chamber 3, and pass through the diffusion nozzle 10, the corrugated plate coalescer 11 and fiber polymerization The device 12 is used to separate and collect oil and water;

[0041] S3. The exhaust gas enters the biological deodorization chamber 4 through the conduit, and the washing liquid spray pipe 15 sprays the washing liquid. The washing liquid is selected from industrial water, and the washing liquid mixed with VOCs i...

The device has the advantages that the treatment efficiency is high, the combustible gas can be recycled, the treatment cost is low, and the deep treatment effect is improved.

Description

technical field [0001] The invention relates to an oily waste gas treatment device and method, belonging to the technical field of waste gas treatment. Background technique [0002] In the industrial production of the petrochemical industry, oily waste gas is often produced. Moreover, part of the production gas will leak during the process. These gases contain oil gas, dust, alkanes, phenols, sulfur-containing gases, ammonia nitrogen, etc., and will emit a strong odor, which is toxic and irritating to a certain extent. If it is not treated, it will pollute the air environment. Common treatment methods: adsorption method, absorption method, catalytic combustion method, thermal combustion method, biological reagent spray method, etc. [0003] For example, a patent application document with the patent application number "CN201920515943.6" discloses an oily waste gas treatment device and method. It includes a degreasing room, a biological washing room and an advanced treatmen...
