Embodiment

[0032] Such as figure 1 As shown, the malodorous tail gas purification and treatment device in gas extraction wastewater includes a first gas-liquid separation tank 1 , an oxidation absorption tower 2 , and a second gas-liquid separation tank 3 connected sequentially through pipelines.

[0033] In order to ensure that the gas phase separated by the first gas-liquid separation tank can completely and quickly enter the oxidation absorption tower, there is also a connection between the first gas-liquid separation tank 1 and the oxidation absorption tower 2 for transferring the gas phase through the first gas-liquid separation tank. The gas phase separated by the separation tank 1 is sucked into the first exhaust fan 4 in the oxidation absorption tower 2 .

[0034] In order to further purify the tail gas to achieve the best purification effect, the second gas-liquid separation tank 3 is also connected with an activated carbon adsorption tower 5 .

[0035] At the same time, in ord...

Abstract

The invention discloses a device and process for performing purification treatment on stinky tail gas in waste water of gas production, and solves the problem that the stinky tail gas in the existing waste water cannot be treated completely. The device comprises a first gas liquid separation tank, a first exhaust fan, an oxidation and absorption tower, a second gas liquid separation tank, a second exhaust fan and an active carbon adsorption tower which are connected in sequence through a pipeline. The invention also provides the process for performing purification treatment on the stinky tail gas in the waste water of gas production. The oxidation and absorption tower cooperates with the active carbon adsorption tower to filter the tail gas, specifically, the oxidation and absorption tower is used for performing deodorization treatment on the tail gas, the active carbon is used for adsorbing and filtering the tail gas, and finally the purified gas can be directly discharged to the air and condensed liquid can be recycled.

Description

technical field [0001] The invention relates to a purification treatment device for malodorous tail gas in gas extraction wastewater and a treatment process thereof. Background technique [0002] Gas field water is formation water with high salinity produced during the natural gas extraction process, and the quality and quantity of gas field water vary greatly with different gas wells and different stages of gas production. The Puguang gas field water has complex components, deep color, and strong odor. It mainly contains high levels of pollutants such as hydrogen sulfide, oil, chloride, suspended solids, mineral salts, and organic matter. [0003] The Puguang Gas Field is a super-large marine integrated gas field with the largest scale and the highest yield that has been put into production in my country. Is the domestic proven high H content 2 S and CO 2 largest gas field. At present, the mixed gas production capacity has been further increased to 150×10 8 m 3 / a le...
