High-flow low-temperature plasma industrial waste gas treatment device

Abstract

The invention discloses a high-flow low-temperature plasma industrial waste gas treatment device. The device comprises a treatment device tank body arranged on a base and a gas inlet and a gas outlet which are formed on two sides of the treatment device tank body, the treatment device tank body comprises a treatment device circuit control part and a treatment device gas treatment part, wherein the treatment device circuit control part comprises a high voltage through-wall wiring china bottle, a high voltage pulse power supply, a boosting transformer and a matching inductor which are mutually connected with each other, a modulating pulse power supply and a power supply switch control panel; to-be-treated industrial waste gas enters from the gas inlet at the treatment device gas treatment part, and then is discharged from the gas outlet after orderly passing through a gas inlet flow-evening plate and a DBD electrode group. Multi-group co-axial type DBD electrodes can be driven through a single power supply, the driving number can be dozens to hundreds groups of co-axial DBD electrodes, and each electrode can produce uniform discharging, and can produce uniform discharging under small driving power.

Description

technical field [0001] The invention discloses a large-flow low-temperature plasma industrial waste gas treatment device, and relates to the technical field of environmental protection waste gas treatment. Background technique [0002] With the development of the global economy, the problem of environmental pollution has become increasingly prominent, and various types of environmental pollution have emerged one after another, seriously endangering human health and survival. For the safety of human beings, it is imminent to deal with environmental problems. In recent years, many high-tech technologies to control environmental problems have emerged around the world, such as ultrasonic waves, photocatalytic oxidation, low-temperature plasma, reverse osmosis, etc. Among them, low-temperature plasma is an environmentally friendly new technology with high efficiency, low energy consumption, large processing capacity, and simple operation. To deal with toxic waste gas and refract...

Problems solved by technology

[0012] The technical problem to be solved by the present invention is to provide a large-flow low-temperature plasma industrial waste gas treatment device for the defects of the prior art, and the existing DBD high-flow low-temperature plasma industrial waste gas treatment device cannot be driven by a single power supply Insufficiency of multiple DBD electrodes, a "pulse modulation drive technology" and "seed electron induced discharge technology" is proposed. Compared with the existing DBD low-temperature plasma industrial waste gas treatment device, the present invention can drive multiple groups of coaxial electrodes with a single power supply. DBD electrodes, the number of drives can be dozens to hundreds of coaxial DBD electrodes, and each electrode can generate a uniform discharge
