[0002] In the industrial production process, when desulfurization is carried out in the desulfurization tower under the condition of gas-liquid contact reaction, it is necessary to load fillers of certain specifications and quantities in the tower in order to obtain a better gas-liquid distribution state and improve the reaction efficiency. However, after a long period of operation, the gas-liquid reaction is prone to generate solid impurities, and the fillers, especially the lower layer fillers, will be blocked to varying degrees by smoke and crystalline salt. The blockage of the fillers will bring some problems. First, the gas-liquid channel of the reaction system is blocked, and the energy consumption of related medium transportation equipment and facilities increases. Second, when the fillers are severely blocked, the normal distribution of gas and liquid is affected, and the reaction efficiency is reduced, until the normal operation of the related process system is affected, and production is forced to stop.

[0003] Patent CN 201020042637.4 discloses a fast turbulent desulfurization tower, in which a foaming plate, a liquid distributor and a multi-layer gas-liquid contact plate are arranged from top to bottom in the tower body, the bottom of the tower body is a liquid collecting chamber, each gas-liquid contact plate is evenly distributed with diversion holes, a downcomer is arranged between two gas-liquid contact plates, the upper pipe opening of the downcomer is located above the plane of the gas-liquid contact plate, the lower pipe opening is arranged on the plane of the lower gas-liquid contact plate, the uppermost liquid inlet is connected to the liquid distributor, the desulfurization liquid is sprayed down from the liquid inlet through the liquid distributor, the air inlet pipe is arranged in the tower body below the lowermost gas-liquid contact plate, and the liquid outlet pipe is arranged at the bottom of the tower body and connected to the liquid collecting chamber to discharge the liquid. The device reduces the blockage of the internal parts of the desulfurization tower by accelerating the chemical reaction of gas and liquid; but there is still the problem of packing blockage. Summary of the invention

[0008] Furthermore, the drain outlet is provided with a drain pipe; the drain pipe is provided with a filter A; the drain pipe is movably connected to the drain outlet; the filter A is movably connected to the drain pipe. The impurities washed from the lower layer of filler are collected by the filter A to prevent the impurities from affecting the subsequent further processing of the liquid, affecting the subsequent steps or polluting the environment.

[0009] Furthermore, the cleaning pipes are provided with more than three; the booster nozzles on one cleaning pipe are provided with more than three; the booster nozzles are evenly distributed on the cleaning pipes.

[0010] Further, the filter collector includes a collection box and a filter B; the filter B is installed obliquely below the upper filler; the collection box is fixedly installed inside the desulfurization tower, and the inclined end of the filter B. The filter B can filter and clean the impurities in the upper filler to prevent the impurities from falling into the lower filler and causing repeated blockages. The collection box can collect the filtered impurities to prevent the impurities from accumulating on the filter B. The filter B and the collection box can be taken out through the exhaust port for cleaning.

[0011] Furthermore, the desulfurization tower is provided with a redistributor; the redistributor is fixedly installed directly below the filter screen B. The redistributor can evenly distribute the liquid so that the solution is evenly distributed on the lower layer of filler.

[0012] The working principle of the utility model is as follows:

The gas and liquid can be fully and evenly mixed through the upper filler, redistributor and lower filler, which is convenient for handling the gas in the production process. The pressure is measured in real time by the upper pressure gauge and the lower pressure gauge. When the pressure increases, the upper pressure gauge controls the cleaning device above to spray the cleaning liquid through an external controller, and the booster nozzle is pressurized to perform high-pressure cleaning on the upper filler.
