soil remediation engineering equipment

1. Walking soil improvement equipment

the advanced crawler equipment for handling contaminated soil, which is convenient to transport and repair site. The handling capacity of the equipment is 40-150 cubic meters per hour. The treatment process of the equipment is firstly sifting through the inlet to remove the large particle size block in the contaminated soil, and the soil can be fully mixed with the soil through a pesticide spraying device and a stirring device during the conveyer belt to the equipment outlet. There are multiple mixing links in order to minimize the loss of chemicals and achieve efficient treatment of pollutants.

2 Soil tossing machine

The working speed 50-500m/h (50-500 yd / h) depends on the material texture of the object, the maximum driving speed is 2km/h (1.2 mph), and the processing capacity: 6000m3 / h.

3 Screening hopper

It can be used to sift and break the soil, remove some large stones, and make the soil reach the particle size requirement of remediation. It can be used in aerobic stage of soil treatment to plough the soil. The treatment depth is 30-50 cm underground.

4 Volatile gas suppression equipment

A layer of film was formed on the soil surface by spraying the foam agent with imported environment-friendly odor inhibitors to effectively isolate and suppress the toxic gases and irritant odors produced by the working surfaces in the treatment of contaminated soil. Foam sprayed each time can cover 400-700 square meters of work surface, foam lasting more than 12 hours. It has the characteristics of fast, high efficiency, simple operation and fast moving.

5 Mobile thermal desorption system

By heating the soil, the pollutants are volatilized and desorbed into the chamber of the rotary kiln, and a series of dust removal, oxidation, spray, condensation and acid removal are carried out to make the gas discharge up to the standard. At the same time export to the standard clean soil. Handling capacity: 25 tons per hour.

6 Biaxial mixing equipment

Treatment ability: 20 ~ 90m / h, used in soil heterotopic remediation, the effect of mixing soil and pesticide is better.

7 Soil elution equipment

It is suitable for the remediation and treatment of larger soil size. The coarse and fine particles of soil are separated by the principle of soil classification. The coarse particles, such as sand and stone, contain less pollutants and have low adsorption capacity, so they are cleaned with water, and most of the pollutants are enriched in fine particles, which can be treated centrally.

8 In-situ mixing equipment

Through special mixing machine and specially designed drill pipe, drill bit, mixed mixing of contaminated soil can effectively solve the difficulty of mass transfer caused by soil heterogeneity and low permeability. In combination with different subsequent treatment techniques, different process combinations are formed, which are especially suitable for site restoration with complex formation structure and poor soil permeability.

9 High pressure rotary jet equipment

It is used to repair the soil in situ and inject the medicament into the soil under high pressure.
