Problems solved by technology

[0002] Oil refineries, refineries, oil production plants, and refinery sewage treatment stations (factories) all emit oily waste gas. The exhaust gas contains oily substances, odorous components and other components, such as oil, hydrocarbons, benzene, phenol, Hydrogen sulfide, organic sulfur, amino, etc., the oily liquid is easy to deposit on the surface of the filler, which affects the mass transfer of the filler and the metabolism of microorganisms. At the same time, the chemical structure of the oily substance is stable, and there is no good method for treating oily waste gas.
[0003] For a long time, due to the complex composition of oily waste gas, low-concentration oily waste gas cannot be treated by traditional combustion or chemical methods, and can only be discharged directly or treated with activated carbon adsorption. Therefore, there has never been a good solution
A large amount of oily waste gas discharge for a long time not only causes environmental pollution, but also causes a waste of energy

Embodiment Construction

[0013] A treatment method for oil-containing malodorous gas, comprising the following steps:

[0014] (1) oily waste gas is passed through the walnut shell packing layer 2 in the container 1, and sprayed through the atomizing spraying device 3 above the walnut shell packing layer 2;

[0015] (2) passing the waste gas treated in step (1) through the biological filler 4, and spraying treatment through the spray device above the biological filler 4;

[0016] (3) The exhaust gas treated in step (2) is treated by ion oxygen treatment device 5 .

[0017] In the circulating water tank 7, the oil-water mixture obtained by spraying the waste gas is subjected to the oil-water separation process through the oil-water separator 6, and the oil is separated, and the water can be returned to the circulating water tank 7 for reuse. Due to the effect of spraying circulating water, the walnut shells are continuously washed and washed, so as to ensure that the walnut shells can be used repeated...

Abstract

The present invention discloses a method for treating oily odour gas. Said method includes the following several steps: making the oily waste gas be passed through walnut shell filler, then undergone the spray treatment by using atomization spraying device over the walnut shell filler, then undergone the processes of biological method and / or ion oxygen method treatment, so that the oily waste gas can be greatly purified and cleaned.

Description

Technical field: [0001] The invention relates to a method for purifying oily waste gas. Background technique: [0002] Oil refineries, refineries, oil production plants, and refinery sewage treatment stations (factories) all emit oily waste gas. The exhaust gas contains oily substances, odorous components and other components, such as oil, hydrocarbons, benzene, phenol, Hydrogen sulfide, organic sulfur, amino, etc., the oily liquid is easy to deposit on the surface of the filler, which affects the mass transfer of the filler and the metabolism of microorganisms. At the same time, the chemical structure of the oily substance is stable, and there is no good method for treating oily waste gas. [0003] For a long time, due to the complex composition of oily waste gas, low-concentration oily waste gas cannot be treated by traditional combustion or chemical methods, and can only be discharged directly or treated with activated carbon adsorption. Therefore, there has never been a ...
