Recycling device of combustible gas in petrochemical gas and recycling method thereof

Abstract

The invention discloses a recycling device of combustible gas in petrochemical gas and a recycling method thereof. The recycling device comprises a compressing mechanism located on the upper end of apower box body and used for compressing gas, and a gas storage box located at one end of the compressing mechanism and used for temporarily storing gas, a motor drives a second rotating wheel to be inmovable connection through a belt, the second rotating wheel drives the rotating shaft to rotate, a rotating block rotates around the axis of the rotating shaft, a connecting rod moves in the vertical direction while rotating along with the rotating block, a push rod moves up and down along the connecting rod, the push rod pushes a push plate to move upwards, the push plate pressurizes gas in the compression box body, a thrust block is arranged on a guide pipe, the thrust block is of a triangular structure with multiple through holes in the periphery at equal intervals, an arc face is arranged at one end of the thrust block, a through hole of the thrust block can rapidly discharge gas conveyed in the guide pipe into a compression box body, the arc face of the thrust block is matched withthe bottom end arc face of the limiting block, the thrust block can improve the air inlet efficiency, and the gas recycling is accelerated.

Description

technical field [0001] The invention relates to the field of recovery devices, in particular to a recovery device for combustible gas in petrochemical gas and a recovery method thereof, belonging to the application technical field of combustible gas recovery devices. Background technique [0002] Exhaust gas in the chemical industry mainly includes combustion exhaust gas emitted by heating furnaces and boilers in refineries and petrochemical plants; excess gases such as non-condensable gas, relaxation gas, and by-products generated in the reaction produced by production equipment; light oil products, volatile chemicals, etc. and solvent volatilization and leakage during storage and transportation; malodorous and toxic gases emitted during waste water and waste treatment and transportation; and waste gas emitted by volatilization and leakage during the transportation of raw materials and products in petrochemical plants. [0003] Petrochemical gas contains a lot of combustibl...
