Ectopic efficient crushing and mixing integrated remediation equipment for contaminated soil

Abstract

The invention discloses ectopic efficient crushing and mixing integrated remediation equipment for contaminated soil. The ectopic efficient crushing and mixing integrated remediation equipment comprises a feeding and conveying unit, a crushing and screening unit, a pesticide spraying and stirring unit and a maintenance and discharging unit which are arranged on a moving device. According to the mode, the overall intelligent movable arrangement technology integrating the functions of crushing, screening, spraying, mixing and conveying is integrally designed, the equipment can adapt to remediation of various contaminated sites, solidification and stabilization or chemical oxidation agents are added according to the actual situation, the equipment capacity is comprehensively improved, the treatment effect is enhanced, the domestic and overseas technical blank is filled, the crushing cutter and the screening device can be replaced according to the characteristics of different viscosities, particle sizes and the like of the polluted soil, are more targeted, improve the crushing and screening efficiency and the soil agent mixing efficiency, can be effectively applied to various polluted soil treatment scenes with different viscosities and particle sizes, reduce the equipment loss, adapt to the movement of a remediation site, save the movement cost, and improve the equipment efficiency.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an all-in-one remediation equipment for ex-situ, high-efficiency crushing and mixing of polluted soil. Background technique [0002] The ex-situ dosing remediation technology is one of the most commonly used technologies in the existing heavy metal-contaminated soil remediation technologies, such as: solidification / stabilization, chemical oxidation, the key process of which is the mixing of contaminated soil and chemicals; solidification / stabilization or After the oxidizing agent is evenly mixed with the polluted soil, it will fully react to stabilize the heavy metal pollutants and form a solidified body or remove the organic pollutants. At present, the existing ex-situ dosing and repairing mixing equipment has the following shortcomings in practical application: pollution Impurities in the soil are difficult to remove, and the equipment is easily damaged during the mixi...

[0002] The ex-situ dosing remediation technology is one of the most commonly used technologies in the existing heavy metal-contaminated soil remediation technologies, such as: solidification / stabilization, chemical oxidation, the key process of which is the mixing of contaminated soil and chemicals; solidification / stabilization or After the oxidizing agent is evenly mixed with the polluted soil, it will fully react to stabilize the heavy metal pollutants and form a solidified body or remove the organic pollutants. At present, the existing ex-situ dosing and repairing mixing equipment has the following shortcomings in practical application: pollution Impurities in the soil are difficult to remove, and the equipment is easily damaged during the mixing process, and the degree of uniformity of mixing is difficult to ensure; the automatic control and operation of medicaments, technology, equipment, etc. cannot be realized, and the synergy of the entire repair system has not been considered; manual dosing of medicaments is difficult. Accurate measurement takes up a lot of manpower and material resources, and has limited support for actual engineering
