Description

Combined type plasma industrial waste gas treatment facility

Technical field

The utility model relates to a kind of cleaning equipment, especially a kind of combined type plasma industrial waste gas treatment facility.

Background technology

Along with further developing of chemical engineering industry, as industries such as paint, printing, insulating materials, resin leather processing, tin graphed sheet system jar and asbestos, all be in a large number with an organic solvent, and give off the waste gas of harmful substances such as containing benzene, toluene, ethanol, acetone and carbon monoxide.That adopts at present extensively has absorption process, absorption method, burning and a catforming etc.Because polycyclic aromatic hydrocarbon has very high heat-resistant stability, burning method need be heated to very high temperature could destroy them, has caused energy waste like this, can produce more serious secondary pollution again, and etching problem is arranged.Still there are problems such as vapour lock is big, efficient is low in catalytic combustion to the improvement that big flow, high flow rate waste gas are arranged, and sulphur, phosphorus, halogen etc. easily make catalyst poisoning, reduces thereby make catalyst life shorten performance.Absorb biodegrading process and have problems such as adsorption capacity, vapour lock, universality.Have a large amount of active particles in the plasma, these particles can destroy the hard-degraded substance in the environment.Utilizing plasma to come the poisonous and hard-degraded substance in the processing environment is the focus of Recent study.

Summary of the invention

At the deficiencies in the prior art, the design of the utility model by the low temperature plasma catalysis technique provide that a kind of energy consumption is low, handling process short, simple to operate, a kind of combined type plasma industrial waste gas treatment facility of not producing accessory substance, not causing secondary pollution, do not have radioactive material to produce, is applicable to the waste gas of handling scent of, low concentration, big flow and high flow rate.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of combined type plasma industrial waste gas treatment facility, comprise louvered inertial dust collection net, dual zone type static ionized region, dual zone type electrostatic precipitation district, plasma catalytic reactor and pulsed high voltage generator, it is characterized in that: described each part of combined type plasma equipment for treating industrial waste gas is for ease of the standalone module of assembly and disassembly, and described louvered inertial dust collection net is to have multilayer monolithic blinds to overlap each other to combine; Described static ionized region be provided with a plurality of by ceramic insulator fix, parallel to each other, the saw shape that replaces mutually discharge tooth plate and the board-like charged utmost point; Described electrostatic precipitation district also is provided with a plurality ofly has that ceramic insulator is fixed, parallel to each other, the electrostatic precipitation pole plate that replaces mutually; Described plasma catalytic reactor is provided with the plasma high voltage negative pipe of the built-in cat ceramic carrier that matrix form arranges, and the plasma high-voltage positive electrode line that the center is provided with locks on the cone locking bolt by the cone locking nut and is fixed on the plasma high pressure fixed support through the tension adjustment spring.

The beneficial effects of the utility model are: by adopting above-mentioned structure, industrial organic exhaust gas enters dual zone type electrostatic precipitation district through a part of dust-laden particle that louvered inertial dust collection net takes out in the organic exhaust gas, further solid pollutant in the organic exhaust gas is captured, and then enter the plasma catalytic reactor, the plasma space enrichment a large amount of as lively as a cricket high energy electrons, as atom, molecule and the free radical etc. of ion, electronics, excitation state.Because high energy electron contains huge ability, has very strong oxidisability, thereby oxidation and other chemical reactions of a series of complexity take place, and catalyst subsequently will promote the conversion of accessory substance, and the activation energy of reduction reaction, harmful substance is converted into harmless or useful material is reclaimed, thereby make the organic exhaust gas qualified discharge.
