Low-temperature plasma waste gas treatment equipment

Low-temperature plasma exhaust gas treatment equipment mainly uses ions generated by plasma-generating devices to bombard pollutant molecules, ionizing, dissociating and excitating them, and then triggering a series of complex physical and chemical reactions, turning complex large-molecular pollutants into simple small-molecular safe substances, or turning toxic and harmful substances into non-toxic, harmless or low-toxic and low-toxic substances, thereby degrading and removing pollutants.
In recent years, many technologies have emerged around the world to control industrial waste gas pollution problems, such as ultrasonic wave, photocatalytic oxidation, biological method, freezing method, incineration method, etc.Among them, low-temperature plasma is a new environmentally friendly technology that is efficient, low-energy consumption, large processing volume and simple operation to deal with toxic, harmful and difficult-to-degrade substances. Low-temperature plasma equipment is a major scientific and technological achievement in recent years and has an absolute advantage that other methods cannot match.
The low-temperature plasma technology has a wide range of applications. The flow rate and concentration of gas are two very important factors for the application of gaseous pollutant control technology.Biofiltration and combustion technologies can be applied to higher concentration ranges, but are limited by the flow rate of the gas.Low-temperature plasma technology has a wide application range for the flow rate and concentration of gas, and its wide application of low-temperature plasma equipment is self-evident.Plasma technology is simple.The adsorption method should consider the regular replacement of the adsorbent, and secondary pollution may also occur during desorption;The combustion method requires a very high operating temperature;Biological laws must be strictly controlled pH Conditions such as value, temperature and humidity to suit the growth of microorganisms.The low-temperature plasma technology overcomes the shortcomings of the above technologies better. The reaction conditions are normal temperature and pressure, the reactor structure is simple, and the low-temperature plasma equipment can eliminate mixed pollutants at the same time. ( Some cases also have synergies ), No secondary pollution will occur.In terms of economic feasibility, the system structure of the low-temperature plasma reaction device itself is single and compact. In terms of operating costs, microscopic, the discharge process only increases the electron temperature and the ion temperature remains basically unchanged, so the reaction system can maintain low temperature. Therefore, the low-temperature plasma equipment not only has high energy utilization, but also makes the equipment maintenance cost very low.
