Description

A high-efficiency ventilation and oxygen supply device for soil remediation

technical field

The utility model relates to an efficient ventilation and oxygen supply device for soil restoration.

Background technique

During the production and operation of electroplating plants, chemical plants, oil refineries, pharmaceutical plants, and gas stations, a large amount of organic matter, heavy metals and other wastes will accumulate in the soil of the site, causing serious pollution of the site and soil. The complex composition, strong pollution and high concentration of pollutants in the site are potential pollution sources, and some more toxic intermediate products will be produced in the environment. If they are not treated in time for a long time, they will damage the surrounding soil, surface water and even groundwater. Pollution can also enter the human body through the food chain through drinking water or through the soil-plant system, endangering ecological security and human health. Therefore, the remediation of organic or heavy metal-contaminated soil is imminent.

The technologies currently applied to soil remediation are mainly divided into two categories: ex-situ remediation and in-situ remediation; among them, ex-situ remediation needs to concentrate the polluted soil, and then add various remediation agents according to the type of polluted soil to target specific polluted soil. The soil needs ventilation and oxygen supply to ensure the modification effect, but the current solution used in the ex-situ restoration process does not have a good effect of blowing oxygen supply.

Utility model content

The purpose of the utility model is to provide a high-efficiency ventilation and oxygen supply device for soil restoration aiming at the defects existing in the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a soil restoration high-efficiency ventilation and oxygen supply device, including a repair reaction chamber 11, and the repair reaction chamber 11 is provided with a lower isolation plate 4 and an isolation plate 7; A plurality of air inlet holes 5 are evenly distributed on the isolation plate 4, and a plurality of air outlet holes 8 are evenly distributed on the upper isolation plate 7; An air channel 12, an air outlet channel 13 is formed between the upper isolation plate 7 and the upper arm of the repair reaction chamber 11, and a soil repair oxygen supply cavity 14 is formed between the lower isolation plate 4 and the upper isolation plate 7, The soil restoration oxygen supply cavity 14 is provided with a stirring shaft assembly 6, and one end of the stirring shaft assembly 6 is connected to the motor 1 arranged outside the restoration reaction chamber 11; wherein, one end of the air inlet channel 12 is The air outlet is connected to the blower 2 through the air inlet pipe 3 provided; the air outlet at one end of the air outlet channel 13 is connected to the exhaust fan 10 through the air outlet pipe 9 provided.

Further, the output end of the exhaust fan 10 is connected to an exhaust gas cooling tower 15 , and the output end of the exhaust gas cooling tower 15 is connected to an exhaust gas absorption tower 16 .

Beneficial effects of the utility model: the utility model can fully stir the soil in the soil restoration and oxygen supply cavity through the set stirring shaft assembly, and at the same time, the air can be evenly sent into the soil restoration and oxygen supply through the set air inlet channel The front and rear parts in the cavity are fully mixed with the soil being stirred, so that the oxygen in the air can fully contact the soil, so that the ventilation effect is better, the air supply efficiency is higher, and it is beneficial to soil restoration. The set air outlet channel can discharge the waste gas from various parts in the soil repair oxygen supply chamber, which improves the discharge efficiency of the waste gas.
