Modular cleaning device for soil purification

Abstract

The modular cleaning device for soil purification according to the present invention comprises: an input screening unit for cleaning and screening the input contaminated soil; a transfer unit for transferring the contaminated soil; the cleaning part is used for spraying high-pressure water to the polluted soil and stripping pollutants; a contaminated soil separation unit that stirs the contaminated soil, separates contaminants from the purified soil, and discharges only the purified soil; and a discharge unit for transferring the purified soil, the input screening unit comprising: a vibrating hopper which forms an input path and is formed so as to gradually narrow from the upper part to the lower part; a body connected to the vibrating hopper, one end portion of the body being disposed higher than the other end portion of the body; the screening screen is used for screening the contaminated soil with the particle size smaller than the set particle size; a nanobubble spraying means for spraying water to the contaminated soil to induce pre-peeling; and an ultrasonic transducer that generates acoustic cavitation and removes contaminants in advance by means of impact energy when bubbles break.

Description

technical field [0001] The invention relates to a modular cleaning device for soil purification, in particular to a modular cleaning device for soil purification, which utilizes multiple modular structures to continuously screen the input contaminated soil , transfer, cleaning, grading and other processes, so that the foreign matter or pollutants contained in the fine particles in the contaminated soil can be effectively removed, and the cleaning efficiency can be improved. Background technique [0002] Generally, environmental pollution can be divided into air pollution, water pollution and soil pollution. Among them, soil pollution not only poses a very serious threat to food production, but also induces pollution of drinking water sources due to the pollution of surface water and groundwater. Therefore, it is necessary to Decontaminate contaminated soil at an earlier time. [0003] Recently, soil pollution in Korea has occurred mainly due to the unprovoked landfill or le...

[0007] However, the cleaning of the aforementioned content goes through the process of input, screening, elution, neutralization, water treatment, and sludge dehydration in sequence. During the screening and elution process, the solid-to-liquid ratio is more than 1:3, so there are too many water treatment equipment , in particular, in the case of pollution above a certain concentration, the removal efficiency is low only with water, and the contaminated soil is reacted with a cleaning solvent, so 30 minutes of stirring time is required, so there are limitations of continuous treatment and excessive drug costs , and it is accompanied by the disadvantage of the cost of neutralizing the soil affected by the drug, and, with the application of a strong cleaning solvent, there is a disadvantage of destroying the health of the soil and affecting the growth of plants

[0008] Conversely, when only water is used for the separation and removal of pollutants, as described above, the solid-to-liquid ratio is 1:3 or more, resulting in too many water treatment facilities, and if there is pollution above a predetermined concentration, then It is difficult to expect purification efficiency, especially when organic pollutants and inorganic pollutants exist at the same time, there is a limitation of simultaneous application due to the application of different cleaning solvents
