Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of acetylene production, especially to a sewage treatment tank for acetylene gas processing. BACKGROUND

[0002] A large amount of wastewater is generated during the industrial production of acetylene. Since calcium carbide is used to produce acetylene by reacting with water, the wastewater contains a large amount of calcium hydroxide impurities and particulate impurities. However, the sewage containing a large amount of calcium hydroxide is not only strongly alkaline, but also very turbid due to the low solubility of calcium hydroxide, with many impurities. Direct discharge pollutes the environment greatly. At the same time, calcium hydroxide is a good building material and can be used to prepare mortar. Therefore, sewage treatment and filtration not only reduce environmental pollution, but also create additional revenue. Traditional wastewater treatment methods mainly include physical methods (such as sedimentation), chemical methods (such as neutralization reaction), and biological methods (such as activated sludge method). However, there are many disadvantages in the actual use of various treatment methods, such as long time consumption, incomplete treatment, additional cost, etc.

[0003] Therefore, it is an urgent need in the industry to develop a high-efficiency, reliable, and easy-to-manage sewage treatment tank for acetylene gas processing. This new type of treatment tank should be able to effectively remove various types of pollutants while having good continuous working ability and automation level to meet the requirements of modern factories for environmental protection.
