Description
The present invention relates to a horizontal multi-stage soil restoring apparatus, and more particularly, a plurality of agitating vessels are connected in a horizontal manner so that the contaminated soil flows in a natural dropping manner, but crushing and agitating the contaminated soil falling inside of these agitating vessels. While adding a surfactant, hot air, steam and oxidizing agent and providing an adsorption means for adsorbing and removing the contaminant separated from the contaminated soil on the outside of the agitator to remove the contaminant, By side-by-side, a large amount of contaminated soil is dispersed in a narrow space, so that the pollutant can be processed quickly, and the stirring barrels are easy to manufacture because they have the same configuration as the inner rotating shaft, the stirring blade, and the external adsorption means. It relates to a horizontal multi-stage soil restoration system.
Soil washing is the separation of organic pollutants and heavy metals from soil particles by using a cleaning agent to weaken the surface tension of harmful organic pollutants bound to soil particles or to elute them by increasing the solubility of heavy metals. Say. When soils on the surface or basement layer are contaminated by leakage of contents from oil storage facilities such as gas stations, reservoirs, petrochemical plants, or factories or storage facilities that handle organic chemicals, or leakage of contents due to cracks in installation structures. In order to restore the contaminated soil, the organic pollutant may be treated in the field with the ground level intact, or the underground soil may be excavated and pumped to the ground to be physically or chemically purified at the site or any place. Can be.
As a device for excavating soil to remove contaminants, domestic practical registration No. 410721 carries one washing screw for transporting the soil from one end of the soil into the other end where the soil is discharged while spraying the washing water onto the soil. The rear screw does not change the pitch, and the diameter and pitch of the front screw decreases as the pitch goes forward to increase the mixing efficiency with the wash water.
However, since the conventional washing apparatus continuously pushes the contaminated soil from the front and rear screws, the pores of the soil are narrowed, so that the mixing ratio of the wash water and the soil is substantially reduced, and only the push-out structure is expected to improve the purification performance of the contaminated soil. It was hard to do.
Korean Patent No. 404738 is configured in a double tube form inside the inner casing is provided with a screw for pushing the contaminated soil and the outer casing is composed of a tub rotating in the reverse direction with the screw to wash the contaminated soil step by step, but also this Because the outer cylinder is composed of a double pipe and the outer cylinder is rotated, the structure is complicated, and there is no configuration that widens the pores by crushing or spreading the contaminated soil, so it is difficult to expect a great mixing performance of the washing liquid and the contaminated soil.
In view of the conventional problems, the inventors have registered a continuous soil washing apparatus with Patent Registration No. 847262. Its contents are continuously filtered through stones and foreign substances to increase the fluidity by adding surfactants to the contaminated soil, quantitatively transporting them, and injecting high pressure air to activate the escape of pollutants in the fluidized soil. By sequentially removing the soil, and then stepwise transporting the soil with the washing solution, the soil can be treated continuously and the soil can be agitated and biochemically treated.
The present invention is to improve the patent of the present inventors, an object of the present invention is to connect a plurality of stirring barrels in a horizontal manner so that the contaminated soil flows in a natural fall method while stirring the contaminated soil falling inside of these stirring cylinders A surfactant, hot air, steam, and an oxidizing agent are added thereto, and an adsorption means for adsorbing and removing the contaminant separated from the contaminated soil is provided outside the agitator to remove the contaminant, while the cascaded agitator vessels are arranged in multiple rows laterally. By arranging a large amount of contaminated soil in a narrow space, it is possible to deal quickly with pollutants, and also by arranging the agitators in a mobile vehicle to ensure maneuverability. It relates to a soil restoration device.
In addition, since the stirring cylinders have the same configuration as the inner rotating shaft, the stirring blades, and the external suction means, the production of the stirring cylinders installed in multiple stages is convenient, and the soil is processed while flowing in a natural dropping manner, so that separate soil transfer means This is unnecessary and can reduce the production cost, by providing a means for controlling the flow of contaminated soil in the connection pipe of the stirring barrels to control the flow according to the components and the degree of contamination of the contaminated soil, staying and stirring in the stirring barrels The purpose is to provide a horizontal multi-stage soil restoration apparatus that can control the time the pollutant is adsorbed.
The present invention is a contaminated soil in which the contaminated soil is injected and the surfactant is sprayed by a plurality of stirring blades rotated to the rotating shaft of the inner horizontally placed in a horizontal fall while crushing and stirring the contaminated soil; An intermediate agitator barrel for spontaneously dropping contaminated soil falling from the inlet agitator barrel with a plurality of agitator blades rotated in a horizontal direction to increase fluidity by spraying high pressure air while naturally dropping; When the oxidant is injected into the contaminated soil falling from the intermediate stirring barrel discharge stirrer to allow the polluted soil and oxidant to fall naturally by grinding and stirring by a plurality of agitating blades rotated to a horizontal rotating shaft; And the input stirring cylinder, the intermediate stirring cylinder and the discharge stirring cylinders are horizontally connected and composed of adsorption means for vacuum adsorption and removal of the pollutant from the contaminated soil by wrapping the porous screen net formed on the outer circumferential surface of each of these stirring cylinders, respectively. There is a characteristic.
According to the present invention by laying down the stirring vessel having the same structure horizontally and connected in three stages by horizontally zigzag connection so that the contaminated soil introduced into the natural fall, the transport means of the soil is not required separately, so the cost is reduced Have And by arranging a plurality of stirring barrels connected in three rows in a row, the soil can be distributedly processed, thereby reducing the load caused by the operation of each stirring barrel and dispersing a large amount of contaminated soil. Has an elevated feature.
In particular, since the stirring barrels of the present invention have the same configuration as the rotating shaft having the inner stirring blades, the outside of the suction means, and the like, there is a convenient advantage when producing multiple rows of the stirring barrels, and the stirring barrel according to the degree of contamination area. Adjusting the number of them has the advantage of being able to quickly treat the soil in the contaminated area without straining the stirring barrels.
