Problems solved by technology

[0003] When the current soil thermal analysis repair equipment is performing soil restoration, most of the soil is constantly turning the soil when heating the soil, so that the soil can be heated to the specified temperature faster and more uniformly, but during the turning process, dust and other small particles will inevitably be caused. The solid waste is mixed with the volatile organic matter, and then flows into the recovery equipment together, resulting in too much impurities in the recovered organic matter

Embodiment 1

[0021] refer to Figure 1-2 , a system for purification and recovery of organic matter for soil thermal analysis restoration, comprising a purification box 1, an air inlet 2 is provided on the side wall of the purification box 1, a dust filter 3 is embedded in the purification box 1, and a rotating shaft is connected to the purification box 1 4. A plurality of first permanent magnets 5 are embedded on the rotating shaft 4, and a plurality of wind rotor blades 6 are fixedly connected to the rotating shaft 4. The wind rotor blades 6 can be made into a wind cup shape to ensure that the horizontal airflow can push the rotating shaft 4 turn. A plurality of second permanent magnets 7 corresponding to the first permanent magnets 5 are embedded on the dust filter 3 . It should be noted that the magnetic poles of each adjacent first permanent magnet 5 are set oppositely, and the magnetic poles of each adjacent second permanent magnet 7 are set oppositely, so that when the rotating sha...

Embodiment 2

[0027] refer to Figure 3-4 , different from Embodiment 1, the inner bottom of the purification box 1 is provided with a through groove 13, and the inside of the through groove 13 is sealed and rotatably connected with a threaded sleeve 14, and the side wall of the threaded sleeve 14 is provided with a plurality of dust storage tanks 141, The threaded sleeve 14 is internally threaded with a screw rod 15 , and the end of the screw rod 15 away from the threaded sleeve 14 is fixedly connected to the side wall of the slide plug 9 . It should be noted that, if Figure 4 As shown, the threaded part of the screw rod 15 is only distributed in a part of the threaded sleeve 14, and the rest is a polished rod, so that when the screw rod 15 penetrates the side wall of the purification box 1 and enters the threaded sleeve 14, it can be in close contact with the penetrating part. Prevent the air in the air groove 8 from leaking and cannot be inflated to the telescopic air bag 12 .

Abstract

The invention discloses an organic matter purification and recovery system for soil thermal desorption remediation, the organic matter purification and recovery system comprises a purification box, the side wall of the purification box is provided with an air inlet, a dust filter screen is embedded in the purification box, a rotating shaft is rotatably connected in the purification box, and a plurality of first permanent magnets are embedded in the rotating shaft; a plurality of wind wheel blades are fixedly connected to the rotating shaft, and a plurality of second permanent magnets corresponding to the first permanent magnets are embedded in the dust filtering net. According to the invention, the passing organic matter airflow is filtered to remove impurities mixed in the organic matters, and the parts such as the wind wheel blades, the first permanent magnet and the second permanent magnet are arranged, so that the dust filter screen can continuously shake off in the discharge process of the organic matters, and the filtered impurities are shaken off; therefore, the device can continuously and efficiently purify and recover organic matters.

Description

technical field [0001] The invention relates to the technical field of equipment related to soil remediation, in particular to a system for purifying and recovering organic matter for soil thermal analysis and remediation. Background technique [0002] For contaminated soil containing organic matter (such as pesticide-contaminated soil), remediation often uses thermal desorption remediation technology for remediation. By indirectly heating the contaminated soil, the organic matter is vaporized and volatilized and separated from the soil. [0003] When the current soil thermal analysis repair equipment is performing soil restoration, most of the soil is constantly turning the soil when heating the soil, so that the soil can be heated to the specified temperature faster and more uniformly, but during the turning process, dust and other small particles will inevitably be caused. The solid waste is mixed with the volatilized organic matter, and then flows into the recovery equip...
