Self-circulation deoiling type oily waste gas filtering device

Abstract

The invention discloses a self-circulation deoiling type oily waste gas filtering device, and belongs to the technical field of oily waste gas treatment. An oil absorption ball chain is in a local oilabsorption state by adopting a mode of obliquely filtering oily waste gas, the gravity center of the oil absorption ball chain shifts gradually along with local oil absorption weight increment of theoil absorption ball chain, and under the action of self gravity, the oil absorption ball chain automatically rotates, the oil absorption part is moved into an oil stain emulsifier for deoiling, and the deoiled part adsorbs oily pollutants again, so that the cyclic oil absorption and deoiling processes are realized, and the continuous and efficient purification process is performed on the oily waste gas; and in addition, when filter holes and the oil absorption ball chain are blocked, with the accumulation of the oily waste gas, the air pressure is gradually increased, the oil stain emulsifieris forced to be leached on the surfaces of the filter holes and the oil absorption ball chain through a flow guide pipe, and blocked oily pollutants are deeply cleaned, so that the unblocking processis automatically realized, and the continuous purification process of waste gas is further realized.

Description

technical field [0001] The invention relates to the technical field of oily waste gas treatment, and more specifically relates to a self-circulating deoiling type oily waste gas filter device. Background technique [0002] At present, many industries (such as printing and dyeing, petrochemical, paint, food processing, etc.) production operations produce oily waste gas. Oil fume not only affects the function of human macrophages and immune cells, resulting in the reduction of cellular immunity, but also , if long-term exposure to high concentrations of oil-containing exhaust gas, it will cause inflammation of lung tissue damaged by human cells and reduce lung capacity. Organic pollutants in oily exhaust gas can induce changes in the genetic elements of the body, causing damage to the genetic material and protein of the human body, and may cause cancer. For the volatile organic oily pollutants in the exhaust gas, the treatment methods commonly used at present include: wet scr...

Problems solved by technology

[0003] The most used in the prior art is to wash the exhaust gas, and at the same time cooperate with the adsorption filter packing to absorb the oil and smoke particles in the exhaust gas. However, oil is a very viscous substance. After that, it will cause adsorption blockage, which will affect the adsorption and filtration process and effect.
