Vertical oil-gas separation device

Abstract

The invention discloses a vertical oil-gas separation device, which comprises a tank body, wherein the middle-upper section of the tank body is a cylindrical section, the lower section of the tank body is a conical cavity section, an oil liquid outlet is formed in the bottom of the tank body, an oil-gas inlet is formed in one side of the tank body, a gas outlet pipe extending into the tank body isarranged in the center of the top of the tank body, the oil-gas inlet faces the wall surface of the gas outlet pipe, toothed plates located below the oil-gas inlet are arranged on the inner wall of the cylindrical section of the tank body, an oil dispersing plate with a gas flow channel in the center is arranged on the inner wall of the conical cavity section of the tank body, a separation umbrella is arranged in the gas outlet pipe, and the gas outlet pipe is further sleeved with an umbrella sleeve located above the oil-gas inlet and used for blocking gas flow and an accumulated liquid. According to the invention, by using the structure, the oil liquid dispersing effect is particularly good, the multi-path oil-gas separation is achieved in the filtering process, the gas can be well filtered, the oil liquid can be purely collected, and in the process, the problems of wastewater, secondary pollution and the like are avoided, and the treatment cost is greatly reduced.

Description

technical field [0001] The invention relates to an oil-gas separation device, in particular to a vertical oil-gas separation device. Background technique [0002] In the process of waste gas recovery and treatment in oil depots, refineries, wharfs and other oil product shipments, trains, cars, tank cars, tankers, oil tanks, oil storage tanks, etc. are washed and cleaned regularly before changing the storage quality The volatilized toxic and harmful waste gas is recycled into liquid oil, which can avoid the discharge of a large amount of pollutants and has greater recycling economic benefits. [0003] At present, the tank washing waste gas produced in this field in our country is basically untreated and discharged directly. In some cases, washing + adsorption method, low temperature plasma removal method, and oxidative incineration method are used. These treatment methods can achieve certain effects, but there are often problems with treatment. If it is in place, a large amo...

[0003] At present, the tank washing waste gas produced in this field in our country is basically untreated and discharged directly. In some cases, washing + adsorption method, low temperature plasma removal method, and oxidative incineration method are used. These treatment methods can achieve certain effects, but there are often problems with treatment. In place, a large amount of waste water is generated, causing secondary pollution and high treatment costs
