Description

Technical Field

[0002] During the regeneration of wet desulfurization of coke oven gas, a large amount of sulfur foam is generated through flotation. The concentration of sulfur foam varies greatly and the liquid content is too large, which is not conducive to the subsequent process. Therefore, it is necessary to concentrate the sulfur foam through a sulfur foam concentration device.

[0003] The Chinese utility model patent discloses a sulfur foam concentration device (publication number: CN214861511U), which includes a compression box, a filter plate, a feed pipe, a cleaning component and a knocking component. The filter plate is arranged in the compression box, and the filter plate divides the compression box into a filter chamber and a concentration chamber. The feed pipe passes through the side wall of the concentration chamber and extends to the middle and lower part of the concentration chamber. The cleaning component is arranged on the filter plate and is located in the concentration chamber. The knocking component is arranged in the filter chamber and is contacted with the filter plate.

[0004] The above patents and some current sulfur foam concentration devices mostly use plate and frame filter pressing to concentrate sulfur foam.
