Description

Technical Field

[0002] The purification tower is also called gas purification tower, absorption tower, waste gas purification tower and fiberglass acid mist purification tower. Its main function is to remove harmful gases in the waste gas and it is widely used in waste gas treatment processes.

[0003] With the acceleration of industrialization and the improvement of urbanization, air pollution is becoming increasingly serious and has become a major obstacle to sustainable development. Pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides in the air not only affect air quality, but also pose a serious threat to human health, such as causing respiratory diseases and cardiovascular diseases. Therefore, it is particularly important to develop efficient and reliable air pollution control technologies.

[0004] Purification towers are needed in the process of air pollution control.

The upper surface of the partition is fixedly installed with a plurality of limit ring plates, the top of the tower cover is fixedly installed with an air outlet, and a second fan is fixedly installed in the air outlet through a bracket. The bottom surface of the tower cover is fixedly installed with the same limit ring plate at the position corresponding to the partition. The gaps between the limit ring plates are fixed with purification barrels, and the bottom surface of the partition is fixedly installed with a cone. The invention can release polluted air faster and more evenly. The nozzle on the annular water pipe can spray the exhaust gas three times. The contact area between the purification barrel and the exhaust gas is larger, and the filtering speed is faster.

[0005] However, the above patent has the following shortcomings: in order to release the polluted atmosphere more evenly, the exhaust gas can be sprayed three times by setting nozzles on the bronchial, conical and annular water pipes, but since the installation position of the nozzles is fixed, they cannot fully contact the polluted exhaust gas during spraying, resulting in poor purification effect and reduced purification effect; in addition, after a long period of use, a large amount of impurities will accumulate on the purification barrel, which seriously affects the purification effect of the purification barrel and cannot meet environmental protection requirements.
