Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a multiphase oxidation soil remediation system. Background Technology

[0002] Soil remediation refers to the use of physical, chemical, and biological methods to transfer, absorb, and transform pollutants in soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. Among these methods, chemical oxidation remediation technology has two major advantages: minimal secondary pollution and rapid remediation speed. It can effectively save on material, monitoring, and maintenance costs during the remediation process. Furthermore, chemical oxidation remediation offers diverse agent application methods and highly flexible remediation plans, which can be tailored and optimized according to the actual site conditions. Therefore, chemical oxidation remediation methods are widely used. However, since different oxidants have different oxidizing capacities and application ranges, multiphase oxidation technology has begun to be widely used to ensure the remediation performance and scope of the soil.

[0003] Existing multiphase oxidation soil remediation systems generally include a shell, a control switch assembly, and a motor. The shell has movable structures at its four corners on its lower end face, and a discharge structure in the center of its lower end face. The discharge structure includes a discharge pipe connected to the interior of the shell, and a solenoid valve is installed on the discharge pipe. The interior of the shell has a gaseous oxidant feeding structure, and the upper end face of the shell has a feeding structure. Harmful substances in the gas are adsorbed by an activated carbon adsorption cylinder in the gas purification and emission structure, effectively preventing pollution caused by harmful gaseous substances entering the air. The system also has corresponding movable structures, enabling it to be moved.

[0004] While existing multiphase oxidation soil remediation systems have the advantage of adsorbing harmful substances in gases, in actual use, soil, solid-liquid oxidants, and gaseous oxidants are injected into the shell at the same time to purify the soil. This can easily lead to waste of oxidants and some soil not being purified, making it inconvenient to use.

[0005] Therefore, there is an urgent need to provide a multiphase oxidative soil remediation system to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the above-mentioned prior art, which is that in actual use, soil and solid-liquid oxidants and gaseous oxidants are injected into the shell at one time to purify the soil, which easily leads to waste of oxidants and some soil not being purified, and is inconvenient to use. This invention provides a multiphase oxidation soil remediation system.

[0007] To solve the above-mentioned technical problems, the present invention provides a multiphase oxidation soil remediation system, including a casing, a feeding channel and a feeding pipe disposed opposite each other on the top of the casing, and further comprising:

[0008] A rotating rod, which is movably connected to the middle of the inner side of the housing;

[0009] A feeding assembly is disposed on the outside of the rotating rod;

[0010] The feeding assembly includes a first baffle unit and a second baffle unit disposed on the side wall of the feeding channel and the feeding pipe, and a pushing unit disposed between the first baffle unit, the second baffle unit and the rotating rod;

[0011] The feeding assembly also includes an air supply unit located on the outside of the rotating rod.

[0012] The present invention is further provided that: supports are installed at the bottom corners of the casing;

[0013] The bottom of the casing has a discharge port, and a discharge pipe is installed at the discharge port.

[0014] The present invention is further configured such that: a driving component is provided at the bottom of the rotating rod, and a protective shell is provided on the outside of the driving component.

[0015] The present invention is further configured such that the first baffle unit and the second baffle unit have the same structure;

[0016] The first baffle unit includes a slot disposed on the top surface of the feeding channel or the feeding pipe, a baffle plate movably disposed inside the slot, and a reset part disposed on the side wall of the baffle plate;

[0017] There are two sets of reset parts, and the two sets of reset parts are arranged opposite to each other on the side wall of the baffle plate;

[0018] The reset part includes a through hole in the side wall of the baffle plate, a guide rod inside the through hole, a limiting block fixedly connected to the top of the guide rod, and a reset component at the bottom of the limiting block. The reset component is located on the outside of the guide rod.

[0019] The present invention is further configured such that: the pushing unit includes one end of a first stop block and one end of a second stop block fixedly connected to the outside of the rotating rod, the side walls of the first stop block and the second stop block are provided with oblique cut surfaces, the second stop block is located above the first stop block, and the second stop block and the first stop block are arranged perpendicularly to each other on the horizontal plane.

[0020] The present invention is further configured such that: the air supply unit includes a connecting pipe installed on the top of the rotating rod, an air supply channel disposed on the inner side of the rotating rod, a first ring body and a second ring body disposed opposite to each other on the outer side of the rotating rod, a vertical pipe installed between the first ring body and the second ring body, and a jet pipe fixedly connected to the side wall of the vertical pipe;

[0021] A horizontal pipe is provided between the gas delivery channel and the first annulus.

[0022] The present invention is further configured such that a stirring rod is installed on the outer surface of the vertical tube.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. This utility model uses a feeding assembly to add soil and solid / liquid oxidants into the feed channel and feeding pipe, respectively. A connecting pipe is then connected to a gaseous oxidant pipe. A drive unit rotates a rotating rod, which in turn rotates a first and second stop block. When the first stop block rotates to the baffle plate position, the oblique cut surface of its side wall causes the first stop block to press against and lift the baffle plate, allowing the soil and solid / liquid oxidants to enter the machine casing through the feed channel and feeding pipe, respectively. When the second block rotates to the position of the baffle plate, it will squeeze the baffle plate and move it downward, thereby sealing the feed channel and the outlet of the feeding pipe, thus realizing intermittent feeding. In conjunction with the gaseous oxidant pipeline, the gaseous oxidant is transported to the interior of the vertical rod through the connecting pipe, gas delivery channel, horizontal pipe, and first ring body, and sprayed into the interior of the machine casing through multiple jet pipes. When the drive component drives the rotating rod to rotate, it will drive the jet pipe and stirring rod to rotate, thereby making the soil fully mixed with the solid and liquid oxidant and the gaseous oxidant, thus improving the soil purification effect.
