Desulfurizing device

Abstract

The invention discloses a desulfurizing device and relates to the technical field of gas desulfurizing devices. The desulfurizing device comprises a flange base and is connected with a desulfurizing tower through the flange base; one end of a shell is communicated with the upper end of the flange base; gas communication tubes are arranged in the shell, the lower ends of the gas communication tubesare communicated with the desulfurizing tower, and the upper ends of the gas communication tubes are communicated with the lower end of a desulfurizing tank body; inspection manholes are formed in the radial direction of the shell; two or more desulfurizing filters are arranged in the desulfurizing tank in the vertical direction of the desulfurizing tank body; a gas outlet is formed in the desulfurizing tank body on the upper sides of the desulfurizing filters. The desulfurizing device is convenient in cleaning operation, saves cleaning water, enhances a cleaning effect and accelerates the cleaning speed.

Description

Technical field [0001] The invention relates to the technical field of coal gas desulfurization equipment, in particular to a desulfurization device suitable for gas. Background technique [0002] In the production process of coke oven gas, the coal gas usually contains a large amount of sulfur (or there will also be a large amount of sulfur in the flue gas discharged from combustion), so it is necessary to install a filter in the desulfurization tank to absorb the sulfur in the coal gas. However, in the continuous production process, the sulfur in the coal gas often forms a viscous paste, which together with by-product salts and other impurities are adsorbed in the filter screen, clogging the entire filter, causing the coal gas sulfur content to increase. To ensure the quality of gas products, it is necessary to reduce the sulfur content in the gas, clean the filter, and remove the paste-like condensed sulfur and impurities that block the filter. Most of the gas desulfurization...

Problems solved by technology

However, in the continuous production process, the sulfur in the gas often forms a thick paste, and impurities such as by-product salts are absorbed in the screen of the filter, blocking the entire filter, resulting in an increase in the sulfur content of the gas. To ensure the product quality of the gas, it is necessary to reduce the sulfur content in the gas, clean the filter, and remove the pasty condensed sulfur and impurities that block the filter

Most of the gas desulfurization filters in the prior art are baffle plate or swirl plate type. This kind of filter is fixed in the desulfurization tank. After the filter is blocked, the desulfurization equipment needs to be shut down for a long time. The temperature in the desulfurization tank After cooling down to room temperature, maintenance personnel enter the desulfurization tank through the manhole to clean the filter. This maintenance method is labor-intensive, time-consuming, laborious and unsafe
