Title:
INTEGRATED SOIL RESTORATION PHOTOCATALYTIC REACTOR
Document Type and Number:
WIPO Patent Application WO/2018/045771
Kind Code:
A1
Abstract:
An integrated soil restoration photocatalytic reactor, a reactor shell thereof comprising a soil grinding chamber and a three-phase cyclic photocatalytic degradation chamber; the soil grinding chamber is connected to the three-phase cyclic photocatalytic degradation chamber, and a cutting blade (4) is rotatably connected to an inner wall of the soil grinding chamber so as to efficiently, rapidly, and uniformly grind soil; a soil inlet is opened on the inner wall of the soil grinding chamber, and a soil outlet is opened on a bottom wall of the three-phase cyclic photocatalytic degradation chamber; a spraying device is arranged above the three-phase cyclic photocatalytic degradation chamber, an aeration device is arranged below the chamber, and an ultraviolet LED light (8) is arranged in the middle; guide plates (6) are symmetrically arranged on both sides of the ultraviolet LED light (8) so that three phases of gas, liquid and solid may be uniformly mixed and may flow circularly; a surface of the guide plate (6) is coated with a photocatalyst titanium dioxide, thus solving the problem wherein a catalyst is difficult to recycle; the device integrates the functions of cutting and refining soil and photocatalytic restoration of soil, and has the advantages of a small area, a simple structure, a mild reaction condition, absence of secondary pollution, and an efficient and stable treatment effect.
