Structure and principle of Zhongjing injection type plasma waste gas purification equipment

Purification principle of Zhongjing injection plasma equipment

The injected plasma generates instantaneous high energy through high-frequency and high-voltage discharge of double electrode dielectrics. A large number of high-energy electrons bombard the pollutant molecules to ionize, dissociate and excite them, which stimulates a series of complex physical and chemical reactions and turns the complex macromolecular pollutants into simple small molecule safe substances, Or the toxic and harmful substances can be transformed into non-toxic and harmless or low toxic and low harmful substances, so that the pollutants can be degraded and removed. Because the average energy of electrons produced by ionization is 10 EV, the chemical reaction which is difficult to realize or slow in general can be realized by controlling the reaction conditions properly.

When high frequency and high pressure are formed between the dielectrics of the implantable plasma module, the gas is broken down and a mixture of high density electron beam, ion radical, oxygen atom and free radical is produced. Plasma degradation of pollutants is the use of these high-energy electrons, free radicals and other active particles and pollutants in the exhaust gas, so that the pollutant molecules decompose in a very short time, and subsequent reactions occur to achieve the purpose of degradation of pollutants.

Injectable plasma can treat molecular chain structures such as benzene, toluene, xylene, ammonia, trimethylamine, hydrogen sulfide, methylthiol, methylthioether, dimethyl disulfide, carbon disulfide and styrene, sulfide, H2S and VOC, so as to decompose the molecular chain of organic or inorganic polymer malodorous compounds into elemental atoms or harmless molecules. Among them, the active free radicals and highly oxidizing hydroxyl oxygen can react with harmful gas molecules to produce harmless products.

Structure and composition of Zhongjing injection plasma equipment

Zj-dl-k injection plasma purifier generates plasma from clean air, which is injected into the waste gas treatment system through naturally aspirated ion transport mode. Zhongjing injection plasma system adopts integrated modularization, which is composed of filter unit, current sharing hood, demisting and dehumidification, buffer chamber, ion generation module and inverter high voltage device, According to the need to deal with the air volume, select the number of modules for combination.

Advantages of Zhongjing injection plasma equipment

1. Small footprint and light weight: due to the use of clean gas instead of exhaust gas to generate low-temperature plasma, the plasma volume is reduced, and the structure between the components is more compact.

2. High treatment efficiency: the injection plasma reactor only needs clean gas, so that the distance between the electrodes can be reduced, which is conducive to enhancing the density in the module, increasing the activity of generated particles, improving the particle density and improving the purification efficiency without increasing energy consumption.

3. Safety and stability: the exhaust gas does not directly pass through the plasma module, and the flammable and explosive gas will not explode due to the electrode spark. The exhaust gas does not participate in the low-temperature plasma generation process, and will not affect the discharge stability. The process of generating ion energy is more stable and controllable

4. Simple maintenance: simple equipment structure, no additional cleaning system, cooling equipment, etc. Daily cleaning costs less, operation and maintenance costs are low. The equipment is independent of the exhaust pipe, so it can be maintained or cleaned without stopping production.

5. Online adjustable: according to customer demand, the injected plasma can be adjusted in real time during operation.

6. Easy to reform: the injection plasma equipment adopts modular integrated design, which can be applied to various industrial applications, and can be combined with the original gas purification equipment for waste gas transformation and upgrading.
