A few days ago, the ex-situ thermal desorption and pollutant recovery system with a daily output of 200 tons was successfully developed by Chunguang Foundry Machinery Co., Ltd.. The first set of equipment is being assembled, and expected to be delivered by the end of August. It is mainly used in the remediation of organic contaminated soil while recovering pollutants. “At present, it is among the best in the single-line repair speed and purification effect in the domestic market.” said Wang Hongyu, manager of the company’s R&D department.

In the workshop, a technician is assembling the core part of the equipment--the spiral thermal desorption heating chamber, which is the “heart” of this set of equipment, adopting the most advanced spiral thermal desorption technology in the field of contaminated soil remediation, to perform spiral stirring and indirect heating on the sieved contaminated soil. The organic pollutants are completely vaporized and recycled, to restore soil and recycle pollutant.

“The heating chamber can be operated all around the clock with stable operation and efficient purification. The recovered soil perfectly reaches the standard of oil content less than 1%, and moisture content less than 5%.” Wang Hongyu said.

The organic contaminated soil mainly refers to volatile and semi-volatile organic contaminated soil and hydrocarbon contaminated soil in the city and its surrounding areas, which will cause serious harm to human health and the ecological environment, thereby restricting the construction and development of the city. At present, the demand for all kinds of organic contaminated soil remediation equipment is robust, and the thermal desorption technology is favored due to its high pollutant removal rate, short remediation period, and good applicability.

“The market demand for soil remediation equipment is robust. The company has made plan to develop and produce 3 series of products based on technologies of leaching, ex-situ thermal desorption, and in-situ thermal desorption, with an annual output value of about 200 million yuan, and received a large amount of orders.” said General Manager Wang Naichun, “In the next step, we will continue to increase research and development, optimize technology, improve efficiency, reduce energy consumption, and strive to contribute to the development of the environmental protection industry in China.”
