Description

Technical field [0001] The invention relates to a vertical plasma and adsorption air purification device provided with spraying and bubbling washing, which is mainly suitable for large-scale indoor air purification and humidity control, and can also be used for pollution control of industrial waste gas. Background technique [0002] People spend at least half of their lives indoors. Because indoor space is effective, there is less exchange with outdoor space. The indoor environment itself not only has no natural purification ability, but also because of the popularity of indoor decoration and air conditioners. As well as people’s daily life, pollutants are continuously emitted into indoor spaces, mainly harmful substances such as volatile organic compounds, suspended solids and aerosols, such as formaldehyde, toluene, xylene, benzene, amines, ammonia, etc. Air pollution seriously harms human health. The main pollutants include formaldehyde and benzene series. Therefore, with the ...

Problems solved by technology

[0007] Since the invention sets the ground electrode in a cylindrical shape and installs the discharge electrode on the axis of the cylindrical ground electrode, the uniformity of the electric field is ensured, and good ionization can be generated in the entire ionization space, and it is not easy to occur due to local shocks. The phenomenon of destroying the overall discharge due to penetration, the space in the cylindrical ground electrode constitutes the air flow channel of the plasma purification chamber; because the uniformly distributed discharge thorns are arranged on the discharge electrode, it is helpful to form a strong electric field near the discharge thorns, In order to ionize the water molecules in the air, a good ionization is formed at a lower voltage, so as to avoid the harsh requirements on insulation, anti-creepage and air parameters due to excessive voltage requirements, which is beneficial to Simplify the equipment structure; because the discharge thorns are evenly distributed on the discharge electrode, it is beneficial to the discharge and ionization everywhere, forming a higher plasma density to speed up the purification speed and improve the purification effect; The washing room is improved, the concentration of pollutants in the air is reduced, and the water content in the air is increased, which helps to improve the ionization characteristics in the plasma purification chamber, increase the plasma concentration, reduce the pollutant load of plasma purification, and improve the purification Therefore, the air enters the water tank from the bottom of the water tank downward from the air inlet pipe, and when it passes through the orifice plate, it breaks through the water surface above the orifice plate, forming a large number of air bubbles. During the collision with the water, the solid particles and gas in the air Substances such as sol are wetted by water and enter the water, soluble organic molecules dissolve in the water, and part of the water molecules enter the air to form water vapor in the air. After the air flows out of the water surface, it is sprayed and washed and humidified, thereby improving The effect of air humidification and washing and purification is improved; because this washing and purification method has relatively strong impact resistance, in the case of changes in pollutant concentration, the pollution level in the air can still be controlled within a certain range. This ensures the reliability of the purification equipment and improves the adaptability; because this humidification method enters more water vapor into the air when the air is dry, and less water vapor enters the air when the air is humid, and even no longer sends water vapor to the air. Diffusion of water vapor (dynamic balance) in the medium, thereby realizing the automatic adjustment of air humidity, and there will be no excessive humidification like the existing air humidifier; due to the sealed overflow structure, through the overflow method It can maintain the thickness of the water layer on the orifice plate to ensure that it is in a good working condition, and the sprayed water can also be circulated back to the water storage tank to realize water recycling, and there will be no external air entering the shell from the overflow port Situation; Since the adsorption layer is set above the plasma purification chamber, and its adsorption material is activated carbon fiber with noble metal cold catalyst, it can further remove the residual gas in the air through physical filtration, physical adsorption, chemical adsorption and catalytic decomposition. Pollutants such as volatile organic gases can further improve the air purification, thereby improving the purification ability of the equipment and helping to reduce the volume and cost of the equipment
