AI Technical Summary

Technical Problem

During the desulfurization and purification process of coke oven gas, scale easily forms at the flue gas inlet of the desulfurization absorption tower, affecting the flow field distribution and leading to a decrease in desulfurization and purification efficiency.

Method used

The system employs a coordinated design of flow equalization plate, support components, and flushing components. Through the cooperation of the pressure relief module and the flushing components, scale on the flow equalization plate is removed in a timely manner, ensuring the continuity of the flow field distribution.

Benefits of technology

It effectively avoids the impact of scaling on the flow field distribution, ensures the continuity and efficiency of desulfurization and purification, and improves the desulfurization and purification effect.

Abstract

This invention discloses a desulfurization and purification device for coke oven gas, comprising a desulfurization tower, a spray pump, a spraying device, a flow equalization plate, a support assembly, a pressure relief module, a flushing assembly, and connecting parts. The desulfurization tower has a flue gas inlet; the spraying device is located inside the desulfurization tower, and the flow equalization plate is rotatably connected to the flue gas inlet via a pivot. The support assembly includes a cylinder and a support rod. The cylinder is embedded in the outer wall of the desulfurization tower, and one end of the support rod has a piston that engages with the cylinder. The other end of the support rod extends into the desulfurization tower and is connected to the flow equalization plate. The piston divides the inner cavity of the cylinder into a first cavity and a second cavity. The pressure relief module communicates with the first cavity. The flushing assembly includes a flushing valve, which is at least partially located at the flue gas inlet. One end of the connecting part is connected to the pivot, and the other end is connected to the flushing valve. This desulfurization and purification device can promptly remove scale from the dry-wet interface inside the desulfurization tower, preventing the accumulation of scale that could affect the flow field distribution.
