Oil fume treatment device and method combining water curtain and bubbling

Abstract

The invention discloses an oil fume treatment device and method combining water curtain and bubbling. The connecting pipe is connected with the upper part of the spray pipe through a flange, and the lower part of the spray pipe is connected with a support pipe through a flange. The inside of the support pipe is provided with a lifting pipe that can be lifted along the inner wall of the support pipe. , the support tube is installed on the cover plate of the liquid collection pool, and the liquid collection pool is a semi-closed structure. In the present invention, the oil fume enters the connecting pipe through the frequency conversion fan, the liquid in the liquid collection pool enters the spray pipe through the water pump to form a water curtain, and the oil fume is sprayed, and the treated oil fume is introduced into the liquid in the liquid collection pool through the lifting pipe for two Secondary purification treatment, the invention has simple principle, easy operation, low cost and obvious purification effect, which has important significance for reducing the harm of oil fume to the environment.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an oil fume treatment device and method combining water curtain and bubbling. Background technique [0002] Oil fumes contain aldehydes, ketones, hydrocarbons, fatty acids, alcohols, esters, lactones, heterocyclic compounds, aromatic compounds, etc. These compounds are not only harmful to human health, but also cause serious pollution to the atmosphere. At present, the commonly used oil fume treatment methods include thermal oxidation incineration method. The principle is to use high-temperature oxidation reaction to convert harmful components in the oil fume into carbon dioxide and water. This method is complex in technology, high in operation and maintenance costs, and is not suitable for oil fume with low air volume. Disposal; the electrostatic deposition method is to introduce oil fume into a high-voltage electric field, and the harmful components are decompo...

Problems solved by technology

At present, the commonly used oil fume treatment methods include thermal oxidation incineration method. The principle is to use high-temperature oxidation reaction to convert harmful components in the oil fume into carbon dioxide and water. This method is complex in technology, high in operation and maintenance costs, and is not suitable for oil fume with low air volume. Disposal; the electrostatic deposition method is to introduce oil fume into a high-voltage electric field, and the harmful components are decomposed and transformed under the action of the electric field. This method will reduce the purification efficiency over time, and the cleaning is difficult; Full contact to achieve purification. This method is simple in technology and good in adaptability. By adjusting the composition of the absorption liquid, different types of oil fumes can be effectively purified.
