Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for petroleum additive production. Background Art

[0002] Petroleum additives are widely used in the process of oil extraction, processing and transportation. They can improve oil recovery efficiency, improve oil quality, promote oil flow, etc. Petroleum additives will produce waste gas during the production process. These waste gases usually contain volatile organic compounds (VOCs), sulfides, nitrides and other harmful substances. In the treatment of petroleum additive waste gas, the spray device is a commonly used treatment equipment. The spray device sprays washing liquid through the spray system to make it contact and react with the harmful substances in the waste gas, thereby achieving the purpose of purifying the waste gas.

[0003] However, when using a spray device to treat exhaust gas, the exhaust gas moves from bottom to top and the scrubbing liquid moves from top to bottom. During their relative movement, the contact time is short, which makes it difficult for some harmful substances in the exhaust gas to be captured by the scrubbing liquid, resulting in poor exhaust gas treatment and purification effects. Summary of the invention
