Description

technical field [0001] The invention relates to equipment for treating industrial wastes containing chlorinated organic substances, in particular to an infrared heating semi-sealed alkali catalytic reaction equipment for industrial wastes containing chlorinated organic substances. Background technique [0002] In recent years, the harm of persistent organic pollutants (POPs, Persistent Organic Pollutions) to the human body and the environment has become the environmental focus of countries all over the world. POPs are generally toxic, including carcinogenicity, reproductive toxicity, neurotoxicity, and endocrine disrupting properties. What's more serious is that on the one hand, POPs have strong lipophilicity and hydrophobicity, and can bioaccumulate in the fat tissue of biological organs, and gradually enlarge along the food chain, so that POPs that exist in low concentrations in the atmosphere, water, and soil Pollutants are magnified through the food chain and cause seri...

Problems solved by technology

[0005] The traditional alkali-catalyzed process mainly has the following problems: (1) The traditional electric heating method has a slow heating rate and low energy utilization efficiency, which leads to an increase in the reaction time of each batch, a reduction in the processing capacity of the equipment, and an increase in energy consumption; (2) The tail gas outlet is open (3) The reaction is a sequential batch type. After the dechlorination and detoxification reaction of chlorinated organic compounds is completed, it is necessary to wait for the reaction materials to cool from the reaction temperature above 300°C to The material can only be discharged after normal temperature, resulting in a decrease in energy utilization and processing capacity. At the same time, the excessive alkaline substances added during the reaction will agglomerate during the cooling process, resulting in difficulty in discharging; (4) Condensation generated after high-temperature tail gas condensation Generally, the condensate is treated with full reflux or no reflux. No reflux will lead to a decrease in the efficiency of alkali-catalyzed dechlorination of chlorinated organic substances. When all reflux is performed, the moisture in the condensate will easily cause an instantaneous increase in the pressure in the alkali-catalyzed reactor. certain risk

In addition, at present, there is no engineering practice of alkali-catalyzed treatment of chlorinated organic industrial waste in China, and there is a lack of complete treatment system equipment
