Low temperature plasma odor treatment system



Odor exhaust gas treatment technology

Technical introduction of odor exhaust gas treatment technology

DDBD (Double Dielectric Barrier Discharge) plasma industrial waste gas treatment equipment and technology is jointly developed by the company and Northeastern University and Shenyang University of Technology. A series of complex chemical reactions such as oxidation are then purified by multi-stage purification, so as to eliminate various odor and odor pollutants emitted from various pollution sources.


Odor waste gas treatment technology process

Under normal working conditions and conventional meteorological conditions, the exhaust gas meets the requirements of the secondary emission standard of the "Odor Pollutant Emission Standard" (GB14554-1993) after being treated by the DDBD dielectric barrier discharge low-temperature plasma system, which meets the environmental protection requirements. It has obvious effects on the eight odorous substances specified in it: hydrogen sulfide, ammonia, trimethylamine, methyl mercaptan, methyl sulfide, carbon disulfide, styrene, and dimethyldisulfide.

The low-temperature high-efficiency ion oxidation reactor is a square integrated equipment, and the reaction tube, power supply, discharge plate, voltage drive, and control system are all assembled in the integrated equipment shell, and the equipment has the advantages of good treatment effect, low operating cost, no secondary pollution, strong impulse load resistance, stable and reliable operation, instant opening and use, immediate shutdown, and no special person on duty.


Technical characteristics of odor waste gas treatment

(1) High-tech innovative products: "low-temperature plasma" technology is an electrochemical process under the comprehensive action of electronics, chemistry and catalysis, which is a new field of technological innovation. It relies on the chemical bond energy of the powerful electric field energy generated by the plasma in an instant to ionize and crack harmful gases, thereby destroying the molecular structure of the exhaust gas and achieving the purpose of purification.

(2) Efficient exhaust gas purification: This equipment can efficiently remove volatile organic compounds (VOC), inorganic substances, hydrogen sulfide, ammonia, mercaptans and other major pollutants, as well as various odors, with a deodorization efficiency of more than 98%, and can be removed within 24 hours for long-term diffuse and accumulated odors and odors, and has the ability to effectively kill bacteria, viruses and other microorganisms in the air, and has obvious anti-mildew effect. The deodorization effect exceeds the first-class standard for odor pollutant discharge promulgated by the state.

(3) No need to add any substances: low-temperature plasma waste gas treatment is a dry purification process, which is a new purification process, without any additives, no wastewater, waste residue, and no secondary pollution.

(4) Strong adaptability: long-lasting purification function, no need for special supervision. It can adapt to the purification treatment of high concentration, atmospheric volume and different gaseous substances, and can operate in the environment of high temperature 250 °C and low temperature -50 °C, especially in the humid and even saturated air humidity environment, it can still operate normally, work continuously 24 hours a day, and operate stably for a long time.

(5) Low energy consumption: low operating cost and power saving are one of the core technologies of "low temperature plasma" patent, which can treat 1000m3/h odor and consume only 0.25 degrees.

(6) No mechanical action, high degree of automation, simple process, simple operation, convenient without special management and daily maintenance, automatic shutdown alarm in case of failure, only need to do regular inspection.

(7) Strong equipment combination: "low-temperature plasma" products are light in weight and small in size, and can be placed vertically and horizontally according to the requirements of the site, and can be designed in series and combination according to the exhaust gas concentration, flow rate and composition to achieve complete exhaust gas purification.

(8) Long service life: This equipment is composed of stainless steel, copper, molybdenum, epoxy resin and other materials, with strong oxidation resistance and good anti-corrosion performance to acid, alkali gas, humid environment, etc. The service life is more than 15 years.

(9) Safety: The voltage used in the "low-temperature plasma" equipment is below 36 volts, which is safe and reliable.
