Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of desulfurization tower, and particularly relates to a circulating hydrogen desulfurization tower. BACKGROUND

[0002] Circulating hydrogen is a product of oil-gas-water three-phase separation of reactor outlet in high-pressure separation device in a crude oil treatment process, and the circulating hydrogen is recycled. The desulfurization tower is needed to remove sulfides in the circulating hydrogen.

[0003] The existing desulfurization tower generally comprises a tower body, an air outlet is arranged at the top of the tower body, a gas distributor is arranged in the tower body, a fan is connected to the gas distributor, a storage tank is arranged below the gas distributor, an oxidizing air inlet is arranged in the storage tank, a sprayer is arranged above the gas distributor, a delivery pump is connected to the sprayer, a demister is arranged above the sprayer, and the reaction reagent is sprayed out of the sprayer to react with the mixed gas containing mainly sulfur dioxide sprayed out of the gas distributor, so as to remove sulfur dioxide in the mixed gas. Generally, the reaction reagent is ground limestone slurry, which reacts with the oxidizing air in the storage tank to generate gypsum after forming calcium sulfite by reacting with sulfur dioxide. In order to ensure sufficient absorption and prevent corrosion of the tower body, the limestone slurry and the mixed gas need to be input into the desulfurization tower at a set ratio, and the input ratio of the limestone slurry and the mixed gas is set according to the amount of sulfur dioxide in the mixed gas. The limestone slurry is delivered by the power of the delivery pump. Since the blades and the shell of the fan and the delivery pump are inevitably worn during the delivery of the mixed gas and the delivery of the limestone slurry, the delivery pressure and the delivery flow rate are reduced, and the wear rate is not consistent, which causes the input ratio of the limestone slurry and the mixed gas to change with the wear of the equipment, especially the delivery pump. Therefore, the input ratio of the limestone slurry and the mixed gas decreases, which causes incomplete desulfurization due to insufficient input of the limestone slurry or corrosion of the tower body due to a decrease in pH. SUMMARY

[0004] The present application provides a circulating hydrogen desulfurization tower, which can automatically adjust the delivery efficiency of the limestone slurry delivery pump when the flow rate of the mixed gas changes, ensure that the limestone slurry and the mixed gas are input at a fixed ratio, and is not affected by the wear of the delivery pump and the fan. The corrosion of the tower body caused by incomplete desulfurization due to insufficient input of the limestone slurry or a decrease in pH is effectively avoided.

[0005] In order to solve the above technical problems, the present application is solved by the following technical scheme: a circulating hydrogen desulfurization tower, comprising a tower body, the top of the tower body is provided with a gas outlet, the tower body is provided with a gas distributor, the gas distributor is connected with a fan through a gas input channel, the gas distributor is provided with a sprayer above, the sprayer is connected with a slurry input channel, the slurry input channel is connected with a delivery pump located in a slurry storage tank, the gas input channel and the slurry input channel are both provided with a flow detection part, the flow detection part comprises a shell, a disc-shaped cavity is arranged in the shell, a detection flow channel is arranged in the shell and tangent to the sidewall of the disc-shaped cavity, a rotating shaft is arranged through the shell, a flow detection impeller is arranged on the rotating shaft and located in the disc-shaped cavity, the rotating shaft of the flow detection part on the gas input channel is drivingly connected with a first adjusting disc, the rotating shaft of the flow detection part on the slurry input channel is drivingly connected with a second adjusting disc, the first adjusting disc and the second adjusting disc are coaxial, a guide resistance coil is arranged radially on the first adjusting disc, a conductive sliding seat is slidingly arranged on the guide resistance coil, an inclined guide strip is arranged on the second adjusting disc, a sliding block is slidingly arranged on the guide strip, the sliding block is drivingly connected with the conductive sliding seat, a first conductive ring and a second conductive ring are arranged on the rotating shaft of the first adjusting disc or the second adjusting disc, the first conductive ring and the second conductive ring are respectively conductively connected with the end of the guide resistance coil and the conductive sliding seat, the first conductive ring and the second conductive ring are respectively abutted with a first electric comb and a second electric comb, the first electric comb and the second electric comb are connected in series with the delivery pump, when the rotating speed of the first adjusting disc is greater than that of the second adjusting disc, the conductive sliding seat slides to reduce the resistance connected in series with the delivery pump, the voltage of the delivery pump increases;

[0012] Compared with the prior art, the circulating hydrogen desulfurization tower has the following beneficial effects: when the circulating hydrogen desulfurization tower is in operation, the flow detection part on the slurry input channel and the flow detection part on the gas input channel detect the slurry flow and the gas flow respectively, and when the circulating hydrogen desulfurization tower is designed, the rotating shaft of the flow detection part on the gas input channel is connected with the first adjusting disc through a transmission mechanism, and the rotating shaft of the flow detection part on the slurry input channel is connected with the second adjusting disc through a transmission mechanism, so that when the slurry and the gas are added according to the set mixing ratio, the first adjusting disc and the second adjusting disc rotate at the same speed, that is, the sliding block does not slide on the guide strip, and the conductive sliding seat does not slide on the guide resistance coil, at this time, the voltage of the delivery pump is stable, when the gas flow increases, the rotating speed of the first adjusting disc increases, at this time, the conductive sliding seat slides to reduce the resistance connected in series with the delivery pump, at this time, the voltage of the delivery pump increases, and the rotating speed increases, so that the rotating speed of the rotating shaft on the flow detection part on the slurry input channel also increases, so that the first adjusting disc and the second adjusting disc rotate at the same speed again; when the gas flow decreases, the rotating speed of the first adjusting disc decreases, at this time, the conductive sliding seat slides to increase the resistance connected in series with the delivery pump, at this time, the voltage of the delivery pump decreases, and the rotating speed decreases, so that the rotating speed of the rotating shaft on the flow detection part on the slurry input channel also decreases, so that the first adjusting disc and the second adjusting disc rotate at the same speed again, when the first adjusting disc and the second adjusting disc rotate at the same speed, the slurry and the gas can be ensured to be input according to the set mixing ratio, and since the slurry and the gas flow are obtained through the detection of the flow detection part, the slurry and the gas flow are not affected by the wear of the delivery pump and the fan, and although the flow under the same voltage is reduced after the delivery pump and the fan are worn, the voltage of the delivery pump continues to increase when the set mixing ratio is not reached, so that the delivery pump has a relatively higher rotating speed than before, thereby ensuring that the limestone slurry and the mixed gas are still mixed at the set mixing ratio.
