Description

Technical field:

[0001] The utility model belongs to the field of coal coking production, in particular to a desulfurization solution filtering device for coal coking production. Background technology:

[0002] A large amount of coke oven gas, also known as coke oven gas, is produced during the production process of coal coking. It refers to a combustible gas produced when several types of bituminous coal are mixed into coking coal. After high-temperature dry distillation in the coking oven, coke and tar products are produced. At present, with the reduction of high-quality coking coal resources and the increase in prices, in order to expand coking coal resources and reduce coking costs, more and more coking enterprises have to use coking coal with a high sulfur content, which leads to a continuous increase in the sulfide content in coke oven gas. The presence of sulfides will bring various hazards to industrial production and people's lives. In order to avoid the above situation, coke oven gas must be desulfurized.

[0003] However, in the actual production process, the desulfurization efficiency of the desulfurization liquid shows a downward trend, resulting in a large amount of sulfur in the coal gas not being completely removed and environmental emissions not meeting standards. One of the reasons for the decline in desulfurization efficiency is that solid impurities will inevitably enter the solution when preparing the desulfurization solution. When the desulfurization solution enters the desulfurization system, the solid impurities contained in the desulfurization solution will be adsorbed in the equipment used in the system. After long-term use, not only will a large amount of sulfur in the coal gas not be completely removed, resulting in environmental emissions not meeting standards, but it will also affect the normal production of coal coking. Utility model content:

[0004] The utility model aims to provide a desulfurization solution filtering device for coal coking production, and overcomes the shortcomings of the above-mentioned prior art, and effectively solves the existing problem of poor sulfur removal effect.

[0018] Specifically, impurities contained in the desulfurization solution can be filtered out through the filter cartridge 3 provided in the filter tank 1, thereby improving the effect of the desulfurization solution in removing sulfur.

[0019] During actual use, the desulfurization solution enters the filter cartridge 3 in the filter tank 1 through the feed pipe 5. The filter cartridge 3 filters out the solid impurities contained in the desulfurization solution, and the pure desulfurization solution is transported to the next process system through the discharge pipe 6. When the solid impurities filtered out by the filter cartridge 3 are large, the feed pipe 5 and the discharge pipe 6 are closed, the cleaning pipe 7 and the first sewage pipe 9 are opened, and several nozzles 8 spray the water transported by the cleaning pipe 7 evenly at high pressure, and flush the filter cartridge 3.
