Device for degrading pollutant with electron beam radiation

Abstract

The invention discloses a device for degrading a pollutant with electron beam radiation. An injection pump is used for injecting solvent, absorbent and liquid to be treated in a liquid storage tank into a mixer after the solvent, absorbent and liquid to be treated in the liquid storage tank are mixed by a four-way valve in different proportion; the mixed liquid is fully mixed under the action of a magnetic stirrer; a liquid buffer tank receives the mixed liquid which effuses from the upper outlet of the mixer; and a compression pump at a liquid inlet pumps the mixed liquid in the liquid buffer tank into a radiation reaction box to degrade the mixed liquid with radiation. The device can automatically and continuously radiate to degrade organic halogen which is difficult to degrade; and a matched remote control system and a working condition system are independently developed for self-fault diagnosis and manual remote safety monitoring, so that all the performances of the radiation degradation device can be improved.

Description

technical field [0001] The invention relates to the technical field of pollutant treatment, in particular to a pollutant electron beam irradiation degradation device. Background technique [0002] At present, PCBs, dioxins, and waste pesticides (DDT, hexachlorobenzene, etc.) are typical persistent organic pollutants, which are carcinogenic, teratogenic, mutagenic, refractory, and high bioaccumulation. It can directly or indirectly enter the human body and cause harm, so the treatment of this kind of waste has become the primary task after the investigation of the pollution inventory. Common treatment methods for refractory organic halogens mainly include heat treatment methods, such as: high-temperature incineration, plasma, high-temperature melting, and co-processing in cement kilns. The rest are non-incineration treatment technologies, such as: mechanochemical method, alkali metal reduction method, biological treatment method, alkali metal reduction method, gas phase redu...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing radiation degradation technical solutions, the radiation degradation devices used to treat organic halogens are mostly drum-shaped reactors, which often need to manually add the samples to be irradiated again and again, and the non-continuous injection of samples greatly reduces the efficiency of its work. , the labor cost is also very high; and if the operator is close to the radiation source, the health risk of the staff will be greatly increased; at the same time, the chamber size is small, and it cannot be used for large-scale radiation degradation
