Complete set of process equipment for remediation of contaminated soil by heterotopic heat desorption from Henan manufacturers

A complete set of process equipment for the remediation of heterotopic thermal desorption of contaminated soil by Henan manufacturers - Henan Songling Heavy Industries manufactures high-quality thermal desorption equipment for the remediation of contaminated sites, which adopts new technologies with good quality, performance and durability, and is sold directly at the factory price. At present, many remediation technologies have been applied to the remediation of contaminated sites in the agricultural production system. Among them, the heterotopic heat desorption technology has significant advantages such as high pollutant removal rate, short remediation cycle, and strong applicability, so it is widely used in soil remediation projects of contaminated sites in the agricultural production system. The basic principle of this technology is to make the soil reach a certain temperature through direct or indirect heating, and the pollutants in the agricultural production system are converted to the gas phase, volatilized and separated, and then completely removed through the tail gas treatment system, so as to achieve the emission of tail gas up to standard.

The whole set of process equipment for heterotopic thermal desorption of contaminated soil remediation includes contaminated soil storage, pretreatment, dosing, incineration and tail gas treatment. On the basis of the original thermal desorption production line, the feeding port needs to be modified, and necessary feeding devices, pretreatment facilities, qualified storage facilities and laboratory analysis capacity are also required.

Heterotopic heat desorption equipment for remediation of soil pollution a complete set Processing sequence and process: site zoning - ground demolition - soil excavation - transfer and temporary storage - screening, crushing pretreatment - heating pretreatment - thermal desorption equipment - feeding system - indirect thermal desorption disposal - soil and dust discharge - temporary storage for inspection - acceptance - backfilling, site leveling.

Technical principle of contaminated soil remediation equipment. Utilizing the characteristics of high temperature, long gas retention, large heat capacity, good thermal stability, alkaline environment, no waste residue discharge, etc. in the contaminated soil remediation equipment, while producing clinker, burn and solidify the contaminated soil. The polluted soil of the agricultural production system enters the rotary kiln from the flue gas chamber at the kiln tail. The gas phase temperature in the kiln can be as high as 1800 ℃, and the material temperature is about 1450 ℃. Under the high temperature condition of the kiln, the pollutants of the agricultural production system in the polluted soil are transformed into inorganic compounds. The high temperature air flow and the alkaline materials (CaO CaCO3, etc.) to effectively ease the discharge of acidic substances, so that sulfur and chlorine can be converted into inorganic salts and fixed; The heavy metal contaminated soil enters the kiln from the raw meal proportioning system to fix the heavy metal in the clinker.
