Example Embodiment

[0020] Such as figure 1 The soil remediation device for removing organochlorine pesticide components in farmland soil as shown, the system includes 1-raw soil hopper, 2-blast sorter, 3-vibrating sieving machine, 4-magnetic sieving machine, 5-grinding crusher , 6-thermal desorption-plasma pyrolysis reactor, 7-excess heat exchanger, 8-washing purification tower, 9-induced draft fan, 10-adjustable spray tower, 11-waste heat dryer, 12-repairing soil storage warehouse Among them, the farmland soil containing organic chlorine pesticides to be repaired is stored in the original soil hopper 1, where it is collected and the preliminary stabilization process is completed. The soil to be repaired in the original soil hopper 1 is transported by a screw conveyor To the blast sorter 2, where low-density and large-volume impurities such as plastic and paper are removed from the soil, the outlet of the blast sorter 2 is connected to the vibrating screen 3 through a conveyor belt, where the high...

Abstract

The invention discloses a soil restorationdevice for removing organochlorine pesticide ingredients in farmland soil.The system comprises an original soil hopper, a blasting and screening machine, a vibrating screen classifier, a magnetic screening machine, a grinding and crushing machine, a thermal desorption-plasma pyrolysis reactor, a waste heat exchanger, a washing and purifying tower, an induced draft fan, an adjustable spray tower, a waste heat drier and a repaired an oil storage cabin.According to the soil repairing device, the characteristic that organochlorine pesticide ingredients absorbed by soil can be detached and desorbed after being heated is creatively utilized, the organochlorine pesticide ingredients are volatilized into air in the form of vapor, then the vapor is introduced into high temperature plasma flame, the catalytic cracking effect special for the high temperature plasma flame is utilized, and organochlorine pesticide molecular bonds are broken and split into small molecular substances and can be discharged after being purified; meanwhile soil obtained after thermal desorption-plasma pyrolysis purification treatment can be applied to agricultural production repeatedly.

Description

technical field [0001] The invention relates to a soil restoration device for removing organochlorine pesticide components in farmland soil, belonging to the field of soil restoration in environmental protection. Background technique [0002] Organochlorine pesticides are organic compounds that contain organochlorine elements in the components used to prevent and control plant diseases and insect pests. The main components are two types that use benzene as raw material and cyclopentadiene as raw material. The former, such as the earliest and most widely used insecticides DDT and HCH, as well as the acaricides dicofol, dicofol, etc., and the fungicides pentachloronitrobenzene, chlorothalonil, Daofengning, etc.; the latter Such as chlordane, heptachlor, and aldrin as pesticides. In addition, camphene-based insecticides based on turpentine, toxaphene, and bornyl chloride based on terpenes also belong to organochlorine pesticides. [0003] Organochlorine pesticides play an imp...
