Intelligent room temperature desorption remediation equipment and method for volatile organic contaminated soil

Abstract

The invention provides an intelligent normal temperature desorption repairing equipment and method for volatile organic polluted soil. The intelligent precision dosing system intelligently adds soil conditioner to the soil, effectively reducing the moisture content of the soil and improving the soil properties; high-efficiency turning and throwing The system flips the soil according to the soil properties or repair stage; the hot air system blows hot air into the polluted soil to promote the desorption of pollutants in the soil. The intelligent monitoring platform calculates the dosage of soil conditioner and the spraying frequency of soil conditioner according to the test results of soil moisture content; the intelligent monitoring platform calculates the type, spacing, number of sets and frequency of turning gears required according to the soil properties and time; the intelligent monitoring platform calculates the required heating wind speed, temperature, and time according to the pollutant PID value; the intelligent monitoring platform conducts independent training and learning to form the optimal control parameters for volatile organic pollutants, which can be used in subsequent work Directly call the relevant optimal control parameters.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an intelligent, high-efficiency normal temperature desorption repair equipment and method for volatile organic polluted soil. Background technique [0002] Pesticide factories, coking plants, petroleum processing plants and other industrial factories are producing more and more organic pollution to the soil because of the volatile organic compounds in their products. With the change of urban development plan, the factory moved to a new site, and it is urgent to control the soil pollution in the decommissioned factory area to meet the new development plan. At present, normal temperature desorption technology is often used to remediate soil polluted by volatile organic compounds. The repair effect of normal temperature desorption technology is easily affected by the external environment (temperature and humidity, air velocity, etc.), soil properties (texture, moisture con...
