Due to the increasingly serious pollution caused by chemical enterprises, the site left behind by the relocation of enterprises cannot be used directly, because the soil pollution problem on the original site will seriously endanger the health of residents.
The thermal desorption treatment equipment for industrial chemical hazardous waste contaminated soil uses the thermal instability of agricultural production system substances in industrial chemical solid wastes to heat them under oxygen free conditions, so that agricultural production system substances are thermally cracked. Agricultural production system substances are cracked according to their hydrocarbon ratio, forming gas phase (pyrolysis gas) and solid phase (solid residue) with high utilization value, These products are easy to store, transport and use, which makes chemical solid waste reduced, harmless and resourceful.
Thermal desorption technology is a common remediation technology for contaminated soil in agricultural production system. The principle is to heat the agricultural production system pollutants in the soil to a sufficient level through direct or indirect heat exchange under vacuum conditions or when introducing carrier gas. The process in which the pollutants in the agricultural production system can be volatilized or separated from the polluted medium by temperature and enter the gas treatment system.
The environmental protection polluted soil remediation thermal desorption technology pretreatment and feeding system, soil remediation equipment, which is characterized in that, before the operation process of the ectopic soil remediation process, the system includes the feeding workshop, the crushing located in it Screening equipment And feeding equipment; Crushing and screening equipment is used for crushing and screening pretreatment of contaminated soil; The crushing and screening equipment includes crushing and screening equipment, Crushing equipment It is used to crush large construction waste and agglomerated cohesive soil blocks in contaminated soil. The screening equipment is equipped with a screen with a mesh size of 30-60mm to pretreat contaminated soil into materials with a particle size of 60mm; The feeding workshop is equipped with a tail gas collection and treatment system using bag type dust collectors and activated carbon adsorbers to prevent dust and secondary pollution of pollutants during the pretreatment of contaminated soil and feeding process.
The thermal desorption equipment for remediation of contaminated soil by Henan Songling Heavy Industry Chemical Co., Ltd. has good performance, high quality and ex factory price. Interested users are welcome to call for consultation.
