System and method for improving normal-temperature desorption greenhouse treatment efficiency by utilizing high-temperature soil waste heat

Abstract

The invention discloses a system and method for improving normal-temperature desorption greenhouse treatment efficiency by utilizing high-temperature soil waste heat. The system comprises a heat exchange system, a normal-temperature desorption greenhouse floor heating system and a soil dust removal system, wherein the normal-temperature desorption greenhouse floor heating system comprises a heating coiled tube; the heat exchange system comprises a heat exchange flow slot which is connected with the heating coiled tube; the soil dust removal system comprises a dust removal room, a sealed dustproof greenhouse and a transportation riding track; one end of the dust removal room is connected with the heat exchange flow slot; the other end of the dust removal room is connected with the transportation riding track; the sealed dustproof greenhouse is arranged on the upper part of the dust removal room; and the sealed dustproof greenhouse is provided with spraying equipment. The system utilizeswaste heat of high-temperature soil restored by a high-temperature thermal desorption technology as a heat source for heating normal-temperature desorption greenhouse floor heating circulating water,realizes cooling restored soil while improving restore efficiency through the normal-temperature desorption technology, improves normal-temperature desorption treatment efficiency, and reduces investment and operation cost at the same time.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a system and method for improving the treatment efficiency of desorption greenhouses at room temperature by using high-temperature soil waste heat. Background technique [0002] Soil is the material basis for human survival and an important part of the ecological environment. With the development of industry and agriculture and the continuous expansion of urbanization, the soil environment is deteriorating day by day. According to the data of the National Soil Pollution Survey Bulletin jointly issued by the Ministry of Environmental Protection and the Ministry of Land and Resources in 2014, the overall soil environment situation in the country is not optimistic. The problem is prominent. In the types of soil pollution, organic pollution accounts for a large proportion, which is mainly the pollutants produced, dumped and leaked in the production process of industrial and ...

AI Technical Summary

Problems solved by technology

Due to high-temperature pyrolysis, the repaired soil is too high to be transported easily, and the soil particles are very fine, which is easy to generate dust and cause secondary pollution

[0005] Since normal temperature desorption technology is mainly operated at normal temperature, temperature and region have a great influence on the implementation of restoration. In summer or in areas with high climate and high temperature, the restoration efficiency is higher, and a higher pollutant removal rate can be achieved. In autumn and winter or climate It is difficult to achieve ideal treatment efficiency and repair effect in areas with low temperature

[0006] At present, there are no relevant reports on the combination of high temperature thermal desorption technology and normal temperature desorption technology for the treatment of volatile or semi-volatile organic polluted soil.
