Description

Technical Field

[0001] The utility model belongs to the technical field of waste salt treatment, and in particular relates to thermal desorption treatment equipment for industrial waste salt. Background Art

[0002] The main methods for treating waste salt are incineration, thermal desorption, and microwave cracking. Among them, the incineration method can completely destroy the organic matter in the waste salt, but the incineration temperature reaches above 1000°C, the waste salt softens to a molten state, and the incinerator is prone to hardening, which affects the service life. The microwave cracking method heats evenly, but the microwave cracking has selective heating characteristics. The dielectric constant of waste salt and organic matter is low and difficult to heat. In addition, the microwave cracking method is not easy to achieve continuous automated production. The thermal desorption method transfers the organic matter in the waste salt to the gas phase. The waste salt stays in the equipment for a long time, and the desorption efficiency of organic matter is high. Through direct or indirect heat exchange, the organic pollutants and metal mercury in the waste salt are heated and volatilized and separated from them, and the volatilized pollutants are effectively collected and treated.

[0003] At present, in the process of treating industrial waste salt by thermal desorption, it is usually necessary to recycle and reuse the by-product brine through the BPT (resin adsorption + advanced oxidation + Fenton oxidation + inorganic membrane filtration treatment, etc.) process. This method is superior to other processes such as high-temperature incineration and flexible landfill. It can achieve the reduction, harmlessness and resource utilization of by-product brine, and at the same time recover the effective ingredients in the mother liquor for recycling. However, the filtration device used for the inorganic membrane in this process has a relatively fixed size of the inorganic membrane tube in the device, and it cannot be easily replaced with an inorganic membrane tube with a larger or smaller diameter, so its practicality is low.

[0004] Therefore, based on the above problems, we designed a thermal desorption treatment equipment for industrial waste salt. Utility Model Content
