Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil gas recovery, in particular to an oil gas recovery device for two-section tower gas system. BACKGROUND

[0002] Oil gas recovery refers to that volatile oil gas and oil gas during loading by a crane are collected through a main pipeline by one or two methods of absorption, adsorption or condensation, or pollution of the oil gas is reduced, or the oil gas is converted from a gaseous state to a liquid state, and the oil gas is reconverted into gasoline, so as to achieve the purpose of recycling.

[0003] In the last step of the oil gas recovery device, the gas needs to be subjected to adsorption treatment to reduce harmful substances therein, so as to reach the emission standard and ensure environmental protection safety. The existing adsorption treatment is performed by using an adsorption tank to absorb the harmful substances in the gas by using activated carbon in the adsorption tank, and the activated carbon can be replaced after a certain period of use. However, the existing adsorption tank has a simple structure, and no structure is arranged between the gas inlet and the gas outlet, so that the residence time of the gas in the adsorption tank cannot be adjusted, and because the gas entering the adsorption tank from the gas inlet directly hits the activated carbon, the activated carbon directly opposite to the gas inlet is quickly deactivated because of long-time contact with the gas, and the activated carbon far away from the gas inlet is slowly deactivated, so that the activated carbon is not uniformly used. In addition, when the activated carbon in the existing adsorption tank is replaced, only the discharge port can be opened to discharge the activated carbon by using the self-weight of the activated carbon, and when the activated carbon is accumulated and blocked in the interior, the activated carbon needs to be manually taken out for discharge, which is troublesome, and in the process of discharging and feeding, the activated carbon is rubbed and impacted to generate a large amount of dust, the dust falls to the bottom of the adsorption tank, and even accumulates in the gas inlet, so as to affect the gas inlet efficiency and be inconvenient to clean.

This structure causes the second hexagonal plug 31 to be pulled out of the second hexagonal slot 28 when the rotating shaft 14 is lifted, and then the rotating shaft 14 cannot drive the rotating block 12 to rotate, so that the lower movable shutter 13 cannot rotate, and when the rotating shaft 14 is lowered, the second hexagonal plug 31 is caused to be inserted after being aligned with the second hexagonal slot 28, and the torque of the rotating shaft 14 can be transmitted, so that the movable shutter 13 can be driven to rotate by the rotating shaft 14.

[0051] This structure makes the exhaust gas entering the tank body 1 through the air inlet 2 impact on the dispersion head 43 and overflow upward through the gas guide grooves 44, so as to disrupt the airflow and prevent the airflow from concentrating into the activated carbon particles, thereby ensuring that the activated carbon particles can uniformly contact the gas and ensuring the absorption effect and efficiency.

[0052] Working principle: when the gas enters the tank body 1 through the air inlet 2, it is received by the dispersion head 43, and due to its shape and the gas guide grooves 44, the airflow is scattered upward, and then contacts the internal activated carbon particles through the holes of the lower fixed grating plate 11 and the holes of the hole plate 10, and finally flows out from the holes of the upper fixed grating plate 11 and is discharged from the tank body 1 through the air outlet 3.

[0053] In this process, the size of the holes of the fixed grating plate 11 can be controlled according to the amount of gas to be absorbed and purified, and the flow meter on the pipeline connected with the air inlet 2 is used to detect the gas amount. When the gas amount is large, the holes of the fixed grating plate 11 are kept fully open, and when the gas amount is small, the holes of the fixed grating plate 11 are reduced to increase the residence time of the gas in the tank body 1 and slow down its flow rate, so that it can fully contact the activated carbon particles, thereby ensuring the purification efficiency and effect.
