Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an air circulation structure for acid mist washing treatment. Background Art

[0002] The acid mist scrubber uses the contact between gas and liquid to transfer pollutants in the gas into the liquid, and then separates the clean gas from the contaminated liquid to achieve the purpose of clean air. The waste gas passes through the packed acid mist scrubber and is treated by gas-liquid reverse absorption, that is, the liquid is sprayed from the top of the tower downward in the form of mist (or small droplets). The waste gas is discharged into the atmosphere through the tower body (reverse flow). This treatment method can cool the waste gas, condition the gas and remove particles, and then after being treated in the demisting section, it is discharged into the atmosphere;

[0003] After checking the public (announcement) number: CN215026911U, an air circulation structure for acid mist washing treatment is disclosed. This technology discloses "an air circulation structure for acid mist washing treatment, including a washing tower body and an air outlet pipe and an air inlet pipe installed on the washing tower body, an air collecting hood is fixedly installed at the end of the air inlet pipe, a high-pressure air pump is fixedly installed at the end of the air outlet pipe, an air inlet grille is fixedly installed on the lower surface of the air collecting hood, and a guide plate and a fixed frame are fixedly installed in the vertical direction inside the air collecting hood, a filter plate is slidably installed inside the fixed frame, and the end of the filter plate extends to one side of the outer wall of the air collecting hood, an electromagnetic valve is fixedly installed on the air inlet pipe, an auxiliary air pump is fixedly installed on one side of the upper surface of the air collecting hood, and the output end of the auxiliary air pump is connected to the air inlet pipe" and other technical solutions, which have "filtering treatment for incoming exhaust gas, effectively filtering insoluble impurities therein and collecting them, reducing the later cleaning process of the washing tower, and not affecting the treatment effect of the washing tower" and other technical effects;

However, various pollutants will gradually accumulate on the filter plates during use, which requires regular cleaning of each filter plate. However, such cleaning work is not easy, because each filter plate needs to be disassembled and installed separately, which undoubtedly increases the complexity and workload of cleaning.
