A device and process method for treating oil fume tail gas

Abstract

The invention discloses a device and a process method for treating oil fume tail gas, comprising a washing unit, an electrostatic unit and a polishing unit, the washing unit is connected to the electrostatic unit through a pipeline, and the electrostatic unit is connected to the polishing unit Connected through a filter channel, the washing unit includes a flue gas inlet, the flue gas inlet is connected to one side of the washing pipe through a flue gas pipe, a waste reducing device is arranged in the washing pipe, and the other side of the washing pipe is connected to the washing pipe. connected to the separation device, the separation device includes a separation tower, the lower end of the separation tower is connected to the liquid return pipe of the waste reduction device, the upper end of the separation tower is connected to one side of the pipeline, and the other side of the pipeline is connected to the The connection of the electrostatic unit mentioned above can reasonably and effectively solve various problems in the above-mentioned various treatment processes through the device used to treat the oil fume exhaust gas, so as to ensure that the emission requirements for various indicators are up to standard during the exhaust gas emission process.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a process method for a device for treating oil fume tail gas. Background technique [0002] For the purification and treatment of industrial fumes and exhaust gases, the current common treatment processes and technologies include physical interception and filtration, electrostatic degreasing and dust removal, activated carbon adsorption and incineration, etc. Because the fume exhaust gas usually has the characteristics of high content of particulate matter, high temperature, sticky particulate matter, a certain amount of gaseous pollutants (typically such as volatile organic compounds VOCs), and heavy odor. For example, physical interception filtration usually has certain factors such as dirty filter cotton, high temperature resistance, and inability to remove gaseous pollutants. Electrostatic dedusting and degreasing are not resistant to high temperature and cannot ...

AI Technical Summary

Problems solved by technology

For example, physical interception filtration usually has certain factors such as dirty filter cotton, high temperature resistance, and inability to remove gaseous pollutants.

Electrostatic dedusting and degreasing are not resistant to high temperature and cannot remove other pollutants and odors

Activated carbon adsorption has the disadvantages of risk of fire, easy to get dirty and clogged, and the effect of odor removal is not obvious; the high-temperature incineration process has problems such as high investment and operation costs, and the regenerator and heat exchanger are easily blocked by viscous substances, etc.
