Self-extrusion deoiling oil-containing waste gas filtering pipeline

Abstract

The invention discloses a self-extrusion deoiling oil-containing waste gas filtering pipeline, and belongs to the technical field of waste gas treatment. According to the invention, innovative arrangement of a self-rotating oil suction cylinder capable of rotating in a filtering pipe can be achieved, so that oil stains in oil-containing waste gas can be adsorbed by utilizing the oil suction effectof the self-rotating oil suction cylinder; the oil-containing waste gas is used as driving force to force the self-rotating oil suction cylinder to synchronously rotate in the oil suction process, and then the strong magnetic pressure oil sleeve arranged in the rotating direction of the self-rotating oil suction cylinder is used for automatically extruding the oil collecting ball to concentrate oil stains adsorbed on the self-rotating oil suction cylinder; and the contact pressure between the self-extrusion oil collecting ball and the strong magnetic pressure oil sleeve is provided by increasing the air pressure, and self-extrusion deoiling is carried out on the self-extrusion oil collecting ball by virtue of the hardened bipolar oil pressing rod, so that oil stains can be recycled, meanwhile, the self-extrusion oil collecting ball is desorbed to recover oil absorption, the oil stains can be continuously adsorbed, and the oil stain treatment efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a self-extruding deoiling oily waste gas filtering pipeline. Background technique [0002] Oily waste gas is often produced in industrial production, such as the existing printing and dyeing, petrochemical, coating and other fields. During the processing, high concentrations of organic waste gas such as smoke, oil stains, etc. will be emitted, such as gasoline, naphtha and benzene, etc. , not only waste resources, but also pollute the environment, and leave a major fire or explosion hazard. For the treatment of oily waste gas, the industry often converts the oil and gas into a liquid state before processing it. [0003] For example, in the patent application document whose patent application number is "200620077362.1", a kind of degreasing device for oily waste gas is disclosed. An oily waste gas inlet is arranged under the packing layer, and a circulating water tan...

However, the walnut shells used in this utility model are agricultural and sideline products, and its output is small, and the purchase channels are few, and the supply volume and output are affected, so it has little application value in the specific implementation process.

And walnut shells are used as the packing layer. When the oil absorption of the packing layer reaches saturation, the packing layer needs to be replaced. In this process, the cost of production materials and labor costs are relatively large, and it is not suitable for large-scale promotion.

[0004] The oil contained in the exhaust gas is easy to cause great damage to the filter equipment due to its viscous liquid characteristics. Therefore, when the oil is treated, it is generally treated with artificial water or some simple equipment for adsorption treatment, which is inefficient and also It will cause waste of water resources, and the adsorption effect on oil pollution is poor. Often there will still be a large amount of unadsorbed oil pollution in the exhaust gas, which will easily block the filter equipment in the next process and even cause damage. When facing a large amount of oily waste gas filtration, The existing filter layer is easy to adsorb and saturate. After saturation, it needs to be suspended for treatment and desorption before it can be put into use, which greatly reduces the treatment efficiency of oily waste gas.
