Embodiment 1

[0071] Example 1, the high-pressure screw pump adopts LG40-2 single-screw pump, the fan adopts single-stage 2.2KW high-pressure fan from Dongguan Fengchi Electromechanical Equipment Co., Ltd., and the screw conveyor adopts WLS-260 screw conveyor. Processing capacity 1t / d, liquid PCBs insulating oil with a concentration of 86.78%, processing capacity 1t / d, contaminated soil containing 8.11% PCBs.

[0072] PCBs insulating oil is fed into the plasma reactor by a single-screw pump with a pressurization pressure of 7bar and a model number of LG40-2, and the feed flow rate is 2l / min; the contaminated soil containing 8.11% PCBs is sent by a screw model numbered WLS-260 The machine is sent into the plasma reactor at a speed of 20r / min.

[0073] The external size of the plasma reactor is H2000mm×Φ1800mm, and the size of the reaction area in the cavity is H500mm×Φ500mm. There is a set of MGC-200 plasma torch from Shenzhen Maikerui Environmental Technology Co., Ltd., the voltage is AC380...

Abstract

The invention discloses a method and a device for mobile treatment on plasma dangerous waste. The method and the device solve the technical problem of treatment on dispersed organic pollutants. The method comprises that dangerous waste in a dangerous waste field is fed into a plasma reactor in a container of a lorry trailer, and then is cracked and gasified into cracked gas and carbon black in microseconds. The device for mobile treatment on plasma dangerous waste comprises a feeding system, the plasma reactor and a flue gas cleaning system arranged in the container of the lorry trailer. Compared with the prior art, the method and the device realize mobile treatment on dangerous waste, have high treatment efficiency and a low cost, realize effective on-site treatment on dispersed, high-toxicity, small-batch and high-concentration liquid organic pollutants and gaseous pollutants, avoid transfer of dangerous waste, improve economical efficiency and safety, and are suitable for emergency treatment on a scene suffering from a dangerous waste environmental accident.

Description

technical field [0001] The invention relates to a method and device for treating hazardous waste, in particular to a method and device for treating hazardous waste with plasma. Background technique [0002] Hazardous waste HW refers to wastes that are toxic, flammable, explosive, corrosive, chemically reactive and / or infectious, and pose serious hazards to the ecological environment and human health. Hazardous waste has great uncertainty in time and space in each link from production, storage, transfer, treatment and disposal. Therefore, it is necessary to strengthen management from all aspects and improve the technical level of its treatment and disposal to eliminate potential environmental disasters. . Among them, organic pollutants are particularly harmful to the ecosystem and human health, and are more difficult to deal with. The hazards of hazardous waste are long-term and latent, and can last for a long time. Once its harmfulness breaks out, it will not only poison ...
