Soil remediation system

Abstract

The invention discloses a soil remediation system. The soil remediation system comprises a primary spiral conveyer, a vibrating screen, a secondary spiral conveyer, a thermal desorption rotary kiln, a three-level spiral conveyer, a crusher, a first water condenser, a cyclone dust collector, a combustion furnace, a condenser group consisting of a gas condenser and a second water condenser, a bag type dust collector, a draught fan and a cooling tower. The soil remediation system has simple integration, is simple in operation when being used for soil remediation, simultaneously enables the harmful substances in the soil processed at last to be extremely low, can be used in a recycling manner.

Description

technical field [0001] The invention relates to a soil remediation system. Background technique [0002] With the development of industrialization and urbanization, the problems of air pollution, water pollution and soil pollution have become increasingly serious. These pollutions have brought great harm to people. For example, the soil contains excessive heavy metals, which leads to Or vegetables are also polluted, and eventually, they are ingested by people and enter the body, causing many diseases such as bone pain, cancer, etc., to protect the environment, therefore, it is to protect people's health, thereby promoting sustainable economic and social development Healthy living with people. [0003] How to solve the problem of soil pollution has always been a concern of governments and private responsible enterprises in various countries. In the existing technology, the means of dealing with soil pollution problems include: steam extraction, fixation / stabilization, vitrif...

Problems solved by technology

[0003] How to solve the problem of soil pollution has always been a concern of governments and private responsible enterprises in various countries. In the existing technology, the means of dealing with soil pollution problems include: steam extraction, fixation / stabilization, vitrification repair, thermal analysis and other methods , the systems using these methods are too complex, and when the corresponding systems are used for processing, they often cannot solve the fundamental pollution problems well.
