Chemical dosing equipment for additives used for remediation of contaminated soil

Abstract

The invention discloses chemical dosing equipment for additives used for remediation of contaminated soil. The chemical dosing equipment comprises a chemical dosing equipment shell. A chemical mixing chamber is arranged on one side of the chemical dosing equipment shell, and a water tank is arranged on the other side of the chemical dosing equipment shell. A chemical mixing tank is arranged inside the chemical mixing chamber, and universal wheels are arranged at the bottom of the chemical mixing chamber. A one-way valve is arranged above the chemical mixing box, and a spraying pipe is arranged on the side, away from the chemical mixing tank, of the one-way valve. According to the chemical dosing equipment, the spraying pipe is used for spraying and is a perforated pipe, a plurality of through holes are evenly distributed in the surface of the spraying pipe, the spraying pipe is driven by a motor to rotate by 360 degrees, a chemical oxidizing agent is scattered out in all directions from the through holes under the effect of centrifugal force, multidirectional purification of contaminated soil is achieved, the purification area is enlarged, the automation level of remediation is greatly improved, and the labor investment is reduced; and in addition, the remediation effect and the treatment efficiency are improved, and the chemical dosing equipment is high in practicability and has good market competitiveness.

Description

technical field [0001] The invention belongs to the related technical field of contaminated soil restoration equipment, and in particular relates to an additive dosing equipment for contaminated soil restoration. Background technique [0002] At present, the environmental problems caused by soil in our country are very prominent. Some areas have serious soil pollution. High-risk areas of soil have appeared in heavily polluted enterprises or industrial-intensive areas and surrounding areas and suburban areas. As a result, the problem of polluted soil purification has become more and more serious. The country attaches great importance to it. Although the country is constantly strengthening and improving the technology of polluted soil purification, there are still some deficiencies that need to be improved. [0003] There are the following problems in the existing technology of repairing contaminated soil additive dosing equipment: 1. Soil pollution is a problem that has alway...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an additive dosing device for contaminated soil remediation, to solve the problem that the position of the spray head of the existing dosing device proposed in the background technology is fixed, resulting in a limited spraying angle, which cannot fully purify the polluted soil and the existing The volume of the dosing equipment is limited and it needs to reciprocate the loading of chemical oxidants to maintain the work, which increases the labor intensity of the staff.
