Problems solved by technology

[0002] At present, after reprocessing the waste gas and intermediates generated in industrial production, they are used as chemical raw materials. However, the concentration of chemical raw materials obtained in this way is usually low, and they need to be concentrated before they can meet the requirements of industrial chemical industries. The demand for raw materials; for these chemical raw materials, they are usually solutions containing fluorine, sulfur, and chlorine. If they are not concentrated properly, it will cause fluorine-containing gases, sulfur-containing gases, and chlorine-containing gases to be discharged into the air. , causing secondary pollution to the environment
At the same time, in the existing concentration technology, the concentration technology and concentration equipment for the above-mentioned chemical raw materials are generally multi-effect concentration and falling film concentration; and whether it is multi-effect concentration or falling film concentration, high temperature and high pressure steam or hot air are required as heat sources Provide concentration energy, and these high-temperature and high-pressure steam or hot air need to heat and transfer heat to the non-essential heating device after entering the concentration device, resulting in high energy consumption and long concentration time of the overall concentration equipment. The concentration process is complicated, and it is easy to cause blockage of the pipeline of the concentration equipment, resulting in high concentration costs; at the same time, the temperature of the gas discharged after concentration is relatively high, and the absorption of the gas is not complete during the absorption process, resulting in partial gas discharge In the environment, causing secondary pollution of the environment
