Description

Technical Field

[0001] This utility model relates to the field of regeneration tank technology, specifically to a sulfur removal structure for an overflow weir in a regeneration tank. Background Technology

[0002] As can be seen from the reaction principle and process flow of wet oxidation desulfurization, high-quality desulfurization liquid is a prerequisite for ensuring the long-term stable operation of the desulfurization process, and the most important thing is the efficient operation of the regeneration unit. Therefore, in the normal production of wet oxidation desulfurization, the daily control focus is on sulfur recovery management, and the management of the regeneration unit is the heart of the daily management of wet oxidation desulfurization.

[0003] In the desulfurization tower, H2S is absorbed into the desulfurization liquid to form elemental sulfur. Ensuring complete flotation of elemental sulfur in the regeneration unit while simultaneously allowing it to overflow into the next unit for sulfur melting is a crucial task. Due to the high viscosity and tendency to adhere of sulfur foam, it easily deposits in the regeneration tank and clogs the overflow weir, preventing the generated sulfur foam from flowing out normally. The traditional method involves manual cleaning of the overflow weir with wooden sticks at regular intervals. However, this method generates a large amount of odor in the working environment, and workers are easily covered in elemental sulfur during cleaning, resulting in poor working conditions and high labor intensity. Furthermore, this method can lead to uneven overflow, unstable foam layers in the regeneration tank, large overflow fluctuations, and inaccurate foam tank levels. Coupled with inadequate management, this can lead to a decrease in sulfur production, an increase in byproduct salts in the desulfurization liquid, equipment corrosion, and the inability to maintain long-term safe, environmentally friendly, and stable system operation. Summary of the Invention

[0004] In order to solve the many defects of traditional methods for cleaning the overflow weir of the regeneration tank, this utility model provides a new sulfur removal structure for the overflow weir of the regeneration tank.

[0005] This utility model is achieved using the following technical solution:

[0006] A desulfurization structure for a regeneration tank overflow weir includes a regeneration tank overflow weir and a chute arranged in a ring around the overflow weir, multiple backflush pipes, a backflush main pipe, an air pipe, and a desulfurization liquid pipe. The multiple backflush pipes are arranged circumferentially above the chute, and the nozzles of the backflush pipes are aligned with the regeneration tank overflow weir. The inlets of the multiple backflush pipes are all connected to the outlet of the external backflush main pipe. The inlet of the backflush main pipe, the outlet of the air pipe, and the outlet of the desulfurization liquid pipe are connected by a three-way solenoid valve, which is controlled by a time relay. Manual valves are provided on both the air pipe and the desulfurization liquid pipe.

[0007] During use, connect the air pipe inlet to the air source and the desulfurization liquid pipe inlet to the desulfurization liquid source. When the temperature is above 10°C, connect the backflush main pipe to the desulfurization liquid pipe through the solenoid valve. When the temperature is low, connect the backflush main pipe to the air pipe through the solenoid valve to prevent the desulfurization liquid from crystallizing or freezing at low temperature. In addition, the solenoid valve can be flexibly adjusted according to the sulfur precipitation situation through the time relay. Then, spray the overflow weir through the backflush small pipe to realize the sulfur removal operation of the overflow weir of the regeneration tank.

[0008] The beneficial effects of this utility model are as follows: The sulfur removal structure of this utility model solves the problem of sulfur foam that cannot be discharged in time due to sulfur particle accumulation in the overflow weir by setting a small back-blowing pipe around the overflow surface of the regeneration tank (above the chute) and blowing out the corresponding air or desulfurization liquid to the overflow weir at regular intervals according to the temperature or working conditions. Moreover, the structure is simple, low-cost, easy to implement, and has good application feedback. Attached Figure Description
