Remediation device based on soil thermal desorption remediation technology

Abstract

The invention discloses a remediation device based on a soil thermal desorption remediation technology, and belongs to the field of soil remediation, the remediation device based on the soil thermal desorption remediation technology comprises a breather pipe and isolation plates, the lower end of the breather pipe is communicated with a plurality of gas diffusion pipes, and the isolation plates are arranged on the two sides of the gas diffusion pipes; in-situ remediation of soil polluted by organic matters can be realized, high-temperature and high-pressure steam is introduced into a pollutedlayer by inserting a gas dispersing pipe into the polluted soil, and the steam with the organic matters in the soil escapes and then rises into an anti-escape cover, so that adsorption balls adsorb the organic matters, the adsorption balls are suspended through magnetic force, and along with more and more adsorbed organic matters, the adsorption ball falls into a collecting pipe under the action of gravity so as to be collected and treated in a centralized mode, the repairing effect is improved, the deformation piece resets while the adsorption ball falls, and therefore the signal releasing piece is opened to remind the outside world, a worker adds a new adsorption ball, and the repairing effect is further improved.

Description

technical field [0001] The invention relates to the field of soil remediation, more specifically, to a remediation device based on soil thermal desorption remediation technology. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by urban sewage, sludge, and manure. [0003] In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in t...

AI Technical Summary

Problems solved by technology

In the existing technology, the contaminated soil must be cleaned up first, and then placed in a professional device for thermal desorption restoration, which greatly increases the workload and also means that the work efficiency is reduced, and for relatively remote or places with inconvenient transportation, the off-site remediation of soil also greatly increases the cost
