Apparatus for purifying organic matters in waste sulfuric acid

Abstract

The invention relates to an apparatus for purifying organic matters in waste sulfuric acid. The apparatus for purifying organic matters in waste sulfuric acid comprises a gas source, a gas boosting device, a gas heating device, a gas distillation tube and a gas-liquid mixer, the gas source is connected with the gas boosting device through the gas distillation tube, the gas boosting device is connected with the gas heating device through the gas distillation tube, the gas heating device is connected with the gas-liquid mixer through the gas distillation tube, a siphon is arranged in the gas-liquid mixer, a siphon fixation frame is arranged at two sides of the siphon, a gas chamber is arranged in the siphon fixation frame, a gas nozzle is arranged at one end of the gas-liquid mixer, and a catalyst carrier is arranged in the gas nozzle. The apparatus has a simple structure, can be reliably used, can be used independently or together with other equipment, organically combines gas stripping and oxidation which are two means for removing waste sulfuric acid, and can thoroughly remove the organic matters in the waste sulfuric acid.

Description

technical field [0001] The invention relates to a purification device for organic matter in waste sulfuric acid. Background technique [0002] At present, sulfuric acid is the most common chemical in the chemical industry. It is widely used in many industrial sectors. It can be said that the output of sulfuric acid in a country marks the industrial level of a country. At present, the output of sulfuric acid in my country is nearly 60 million tons per year, ranking first in the world, which shows that my country's industry has developed very rapidly in recent years. The use of sulfuric acid can be roughly divided into three situations: either it is fixed in the product as a component of the product, or it is transformed into something that people do not want. By-products, or discharged from the production system in the form of waste sulfuric acid. Sulfuric acid can be used in etching industry, electroplating industry, acid in batteries, chemical fertilizers, explosives, p...

AI Technical Summary

Problems solved by technology

Sulfuric acid can be used in etching industry, electroplating industry, acid in batteries, chemical fertilizers, explosives, pesticides, dyes, petroleum processing, desiccants, purifying agents, and reagents for chemical synthesis, etc. At present, more than 20 million tons must be disposed of in my country every year Sulfuric acid in acid-containing waste liquid contains several million tons of organic waste acid every year, and all kinds of waste sulfuric acid cannot be fully utilized. If it is discharged directly, it will not only lose a lot of resources, but also seriously pollute the environment , with the development of my country's circular economy, how to fully recycle industrial waste sulfuric acid has become an urgent problem to be solved
