A technical device for recycling industrial waste salt
In the production process of organic and inorganic chemical products, a large amount of salty wastewater is produced, which forms solid crystals after evaporation and concentration. The crystalline salt contains a large amount of organic or inorganic impurities. It cannot be used as industrial raw material salt. If it is stacked for a long time, it will take up a lot of space and cause serious pollution and damage to the ecological environment.
At present, the treatment processes for recycling industrial waste salt are generally adopted: one is chemical method, and the other is high-temperature pyrolysis method. The chemical method is used for resource treatment. The process route is long, the investment is large, and the production cost is high. Using the high-temperature pyrolysis method, the process route is short, the production cost is low, the investment is small, and the process meets the requirements of environmental protection, which is in line with the current industrial direction of domestic industrial waste salt recovery and resource utilization.
The high-temperature pyrolysis method uses waste salt to produce industrial salt that meets the national standard. The process should be based on the amount of organic impurities in industrial waste salt and the main components of organic matter. The appropriate process method should be selected.
In recent years, Liaoning Dongda Powder has carried out in-depth research and a lot of experimental work on the resource utilization of industrial waste salt, and used Liaoning Dongda Powder's industrial waste salt resource treatment method in industrial applications, which has become a successful example of industrial waste salt resource utilization.
Liaoning Dongda Powder Co., Ltd. carries out recycling treatment of industrial waste salt. The main process is divided into two types: low organic content and high organic content. The low organic content industrial waste salt treatment adopts a one-step process of cracking and gasification. The resource treatment process of industrial waste salt with high organic content is: salt water crystallization→dehydration→critical graded carbonization→decarbonization purification→finished industrial salt. In the process, the critical graded carbonization technology of Liaoning Dongda powder is realized by a special CC critical graded carbonization furnace (called CC carbonization furnace). CC carbonization furnace is a special carbonization furnace for industrial waste salt. According to the different impurity content of industrial waste salt, different step temperatures are used to carbonize and crack the organic matter in waste salt step by step. Part of the organic matter is converted into gas, and part of the organic matter forms fixed carbon. Finished industrial salt.
This industrial waste salt resource treatment method is an advanced process technology and equipment at present, and it is an advanced, practical, environmentally friendly and energy-saving process technology for the resource utilization of industrial waste salt.
