The shortcomings of investment is big, high energy consumption, not thorough organic matter removal.Because non-thermal plasma trap has high VOCS clearances, operation
The advantages that gas elastic big, cost of equipment is low, product is environmental sound and gradually replace a kind of non-destructive method and two
Class non-plasma technology is widely adopted.
The principle of non-thermal plasma trap is to apply electric energy by gas ionization to accelerate gas-phase chemical reaction, is particularly generated
The free radical of high oxidative carries out gaseous oxidation reaction, and hazardous air pollutants are oxidized into harmless object or less toxic thing.
The processing method of low-temperature plasma mainly has following several：Electron beam discharge, glow discharge, corona discharge, medium
Barrier discharge, gliding arc discharge.There is equipment operating cost height in electron beam discharge, can produce ray, must build during commercial Application
There is radiation proof engineering；Corona discharge has that capacity usage ratio is low, discharge energy is uneven, treatment effeciency is easily by electrode shape
The shortcomings of influence of shape；Dielectric barrier discharge has that capacity usage ratio is low, the non-equilibrium plasma area in creeping discharge reactor
Domain is small, the shortcomings of being not easy to realize industrialization；Glow discharge works under vacuum conditions due to needing, and system is complex, work
Process is batch processing, can not on-line continuous production, efficiency is difficult to improve.Slide arc discharge and be used in processing organic exhaust gas field,
Main experience breakdown phase, equilibrium stage, balance and non-balance transformation stage and non-equilibrium four-stage, the 75%- of energy
85% consumption focused mostly in the non-equilibrium stage, and the conversion of energy focused mostly in the balance and non-balance transformation stage.Slide electricity
Although non-destructive processing method of the arc better than organic exhaust gas and existing destructive processing method, but still processed in units be present
Small, the problems such as energy consumption is higher for the degraded of processed in units amount, ozone processing is not clean is measured, seriously constrains that to slide arc plasma organic
The process of industrialization of waste gas processing method.
Therefore need to develop a kind of new plasma technology to solve energy profit existing for existing VOCs treatment field
Low with rate, treating capacity is small, the problem of processed in units high energy consumption.
The content of the invention：
In view of the above-mentioned problems, the utility model provides a kind of device using slip arc plasma processing organic exhaust gas,
The present invention, to increase electrical discharge arc area, expands reaction zone face by setting energy utilization device in plasma reaction device
Product, extend the balance and non-balance transformation stage for sliding arc discharge, while capacity usage ratio is improved, improve organic exhaust gas
Clearance.
The technical solution of the utility model is as follows：A kind of organic exhaust gas plasma treatment appts, the plasma treatment appts
For plasma reactor, including reactor shell, the gas feed positioned at reactor shell top, the gas of reactor bottom go out
Mouth, the plasma discharge electrode in reactor cylinder body, the power interface for being powered to plasma discharge apparatus；It is described anti-
Answer the energy utilization device for being provided with device cylinder and making slip electric arc area and length expanded.
The energy utilization device is combination or the energy utilization plate of energy utilization plate and energy utilization bar.
Height of the energy utilization plate apart from reactor shell bottom should be less than or equal to plasma discharge electrode
Height of the bottom apart from reactor shell low side；Height of the energy utilization bar apart from reactor shell bottom should be more than or
Person is equal to height of the energy utilization plate bottom apart from reactor shell low side.
The energy utilization plate is arc.
The energy utilization bar or energy utilization plate are metal material.
The material of the energy utilization bar either energy utilization plate is tungsten or copper.
Beneficial effect
1st, expanding the presence of arc device increases electrical discharge arc area, and the capacity utilization ratio of balance and non-balance transformation stage is big
Big to improve, organic exhaust gas is in the time lengthening of high-temperature process state, can improve the treating capacity of organic exhaust gas.
2nd, the clearance that arc device improves organic exhaust gas is expanded, the clearance of organic exhaust gas is up to 99.9%.
3rd, organic exhaust gas is handled using plasma apparatus of the present invention, plasma apparatus Waste gas outlet temperature, entered than waste gas
