Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to waste gas recycling equipment for storage oil tanks. Background Art

[0002] Oil and gas recovery in oil storage depots refers to the collection of volatile gasoline and oil vapor during the process of loading and unloading gasoline and refueling vehicles for the purpose of recycling. The separation of oil and gas from air is achieved by utilizing the adsorption force of adsorbents such as activated carbon, silica gel or activated fiber on oil, gas and air mixtures. The oil and gas pass through adsorbents such as activated carbon, and the oil and gas components are adsorbed on the surface of the adsorbent. After decompression desorption or steam desorption, the enriched oil and gas are sucked into the oil tank with a vacuum pump or liquefied by other methods. However, the adsorption force of adsorbents such as activated carbon on air is very small, and the exhaust gas that is not adsorbed is discharged through the exhaust pipe.

[0003] Existing oil tank waste gas recycling equipment is generally composed of two devices that work alternately. When the activated carbon in one device is saturated, it switches to another device. When users replace the filter plate in the device, the process is cumbersome, which makes the workload of the staff heavy. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The exhaust gas in the oil tank body enters the shell through the air inlet pipe, and the exhaust gas passes through the activated carbon on the filter plate. The oil and gas components in the exhaust gas are adsorbed on the surface of the activated carbon, and then the air is discharged from the exhaust pipe.
