[0002] Coking gas is coke oven gas, and is a by-product of coking industry. It is a flammable gas generated in the coking process, mainly formed by bituminous coal in the coking oven through high-temperature dry distillation. In order to prevent hydrogen sulfide and other sulfides in coking gas from causing adverse effects on the human body and the environment, coking gas is generally subjected to adsorption filtration, so that desulfurization treatment can be formed.

[0071] The working principle of the coking gas desulfurization device is as follows:

[0072] When the coking gas needs to be desulfurized, the coking gas is first introduced into the desulfurization tank 1 through the gas inlet 101, and then the coking gas naturally rises and passes through the activated carbon adsorption plate below, and the sulfide in the coking gas is adsorbed by the activated carbon adsorption plate. The gas after the first adsorption continues to rise and passes through the activated carbon adsorption plate of the upper layer, and is adsorbed again, so that the adsorption effect of the coking gas can be improved to the maximum extent. Finally, the coking gas after twice adsorption is discharged through the gas outlet 102.

[0073] In subsequent use, when the adsorption plates 5 on the two first adsorbent mounting plates 22 need to be replaced, the speed reducer motor is directly started in the forward direction, the output shaft drives the horizontal moving lead screw 132 to rotate, and the horizontal moving seat 133 moves horizontally with the horizontal connecting plate 211. At this time, the first adsorbent mounting plate 22 gradually moves away from the desulfurization tank 1, and the second adsorbent mounting plate 23 gradually inserts into the desulfurization tank 1. Until the first adsorbent mounting plate 22 moves to the side wall of the desulfurization tank 1, the speed reducer motor is turned off. At this time, the adsorption plates 5 on the two first adsorbent mounting plates 22 are removed from the desulfurization tank 1, and the adsorption plates 5 on the two second adsorbent mounting plates 23 are inserted into the desulfurization tank 1. Subsequently, the coking gas is introduced into the desulfurization tank 1 for adsorption and desulfurization, and the downtime is shortened.

[0074] At the same time, the adsorption plates 5 on the first adsorbent mounting plate 22 are removed. When removing, the corresponding driving bolt 12 is directly counterclockwise rotated, and the corresponding two positioning rods 8 are taken out from the corresponding two horizontal clamping grooves 91 through the driving of the driving plate 11. At this time, the used two adsorption plates 5 are no longer clamped by external objects, and then they are taken out directly and new adsorption plates 5 are put into the corresponding two mounting grooves 7. Subsequently, the corresponding driving bolt 12 is clockwise rotated, the two positioning rods 8 are connected with the extrusion block 9 again, and the extrusion block 9 is forced, so that the replacement of the adsorption plates 5 is completed.
