Description

technical field [0001] The invention relates to a plasma and photocatalytic air purification equipment for spraying and washing with a horizontal runner, which belongs to the technical field of environmental protection. Background technique [0002] People spend at least half of their life indoors. Due to the effective indoor space and less exchange with outdoor space, the indoor environment itself not only has no natural purification ability, but also due to the popularity of indoor decoration and air conditioners As well as people's daily life, pollutants are continuously discharged into the indoor space, mainly harmful substances such as volatile organic compounds, solid suspended particles and aerosols, such as formaldehyde, toluene, xylene, benzene, amine, ammonia, etc., causing Indoor air pollution seriously endangers people's health. The main pollutants include formaldehyde and benzene series. Therefore, with the improvement of people's living standards and the aggrav...

Problems solved by technology

[0007] Since the present invention adopts the vertical plate and the discharge rod between the parallel plates to form the discharge structure, by respectively connecting the positive pole and the negative pole of the DC high voltage, both the voltage output end and the power ground, when the voltage is large enough, the vertical The ionization discharge is formed on the airflow channel formed between the parallel plates, and the water molecules and other molecules in the air are ionized by a high electric field to form a complex particle composition including plasma; since the vertical plates are parallel to each other and equidistant , and the discharge rods are also uniformly distributed, so the formed electric field has good uniformity, which is beneficial to ensure that the entire ionization space can generate good ionization, so as to avoid the phenomenon of destroying the overall discharge due to local breakdown; The uniform distribution of the discharge thorns helps to form a strong electric field near the discharge thorns, so as to ionize the water molecules in the air, and form a good ionization at a lower voltage to avoid excessive voltage requirements. Strict requirements on insulation, anti-creepage and air parameters are beneficial to simplify the equipment structure; because the discharge thorns are evenly distributed on the discharge rod, it is beneficial to discharge and ionization everywhere, forming a higher plasma density, In order to speed up the purification speed and improve the purification effect; because the runner humidification chamber is set in front of the plasma purification chamber, the concentration of pollutants in the air is reduced, the water content in the air is increased, and it is helpful to improve the quality of the plasma purification chamber. The ionization characteristics of the plasma can increase the plasma concentration, reduce the pollutant load of plasma purification, and improve the degree of purification; because the air inlet is connected to the space in the middle of the humidification runner, after the air enters the middle space of the humidification runner from the air inlet, it is folded It flows upwards and passes through the side wall of the humidification wheel. When passing through the porous material on the side wall of the humidification wheel, it collides with the water film attached to the porous material, and the pollutant particles in the air and can dissolve into the The organic matter in the water is adsorbed by the water, and at the same time, part of the water vapor enters the air flow, thus realizing the humidification and preliminary purification of the air; since the spray pipe and the nozzle are arranged at the rear and upper part of the humidification wheel, the humidification wheel is continuously increased. The wet runner sprays water, and the sprayed water is in contact with the airflow, which further purifies the airflow of the airflow. After the water is sprayed on the humidification runner, the amount of water on the humidification runner is increased, which is beneficial to improve the humidity of the humidification runner. In addition, the sprayed water also supplements the water in the sink, and the excess water can flow out through the overflow tank and then enter the water storage tank for recycling; due to the strong impact resistance of this wet purification method, in In the case of changes in the concentration of pollutants, the pollution level in the air can still be controlled within a certain range, thus ensuring the reliability of the purifier and improving the adaptability; More water vapor enters the air flow when the air is wet, and less water vapor enters the air when the air is humid, and even no longer diffuses water vapor into the air (dynamic balance). Excessive humidification phenomenon of existing air humidifiers; because photocatalytic ultraviolet lamps and photocatalytic filters are installed above the plasma purification chamber, the remaining volatile organic gases are further decomposed by photocatalytic oxidation, so that the air is further decomposed. purification, helps to improve the High purification capacity, reduce equipment volume and cost
