Description

Technical Field

[0001] The present invention relates to the technical field of recycling devices, and particularly to an inorganic chemical waste liquid treatment and recycling device. Background Art

[0002] Inorganic waste liquid mainly comes from inorganic chemical reactions in industrial production, such as acid-base neutralization, precipitation, oxidation-reduction and other processes. This kind of waste liquid usually contains inorganic substances such as inorganic salts, heavy metal ions, acids and bases. If inorganic waste liquid is directly discharged without proper treatment, it may cause serious pollution to water bodies and soil. Especially heavy metal ions, they will accumulate in the environment and enter the human body through the food chain, causing harm to health. When the existing chemical waste liquid recycling and treatment devices treat chemicals, the chemical waste liquid needs to be transported multiple times, which is likely to cause leakage of the chemical waste liquid.

[0003] Therefore, technicians in the relevant technical fields have made improvements. For example, the "inorganic chemical waste liquid treatment and recycling device" proposed in Chinese Patent Application No. CN201811548272.X can purify inorganic chemical waste liquid and can effectively improve the reaction rate of chemical reagents. However, the technical solution in this application document still has deficiencies.
