Description
Technical Field
The invention relates to the technical field of air purification, in particular to an on-vehicle liquid filter type plasma air purification system.
Background
The vehicle-mounted air purification system is air purification equipment special for purifying PM2.5, toxic and harmful gases (formaldehyde, benzene series, TVOC and the like), peculiar smell, bacteria, viruses and other in-vehicle pollution in the air in an automobile.
The vehicle-mounted air purification system filters and purifies air in the vehicle, eliminates or reduces air pollutants such as dust, pollen, PM10, PM2.5, bacteria, viruses, formaldehyde, nitrogen oxides and the like in the air, and improves the quality of the air in the vehicle. Currently, air purification systems can be divided into three types of technologies according to their principles: 1. a solid high-efficiency filter screen is adopted; 2. electrostatic dust collection is adopted; 3. releasing highly active purification particles such as ozone or negative ions. Air filters based on these techniques have their own disadvantages.
The method of adopting the solid filter screen is to filter and adsorb pollutants in the air by passing the air through a compact solid filter screen, such as a high efficiency air filtration (HEPA) filter screen, active carbon and other solid materials with compact pores. For example, the method (Chinese registered patent application number) has poor filtering effect on small-particle-size dust particles and gaseous pollutants in the air, and the filtering effect of the filter screen is reduced along with the increase of the service time, so that the filter screen needs to be replaced periodically to generate solid wastes, the use cost is increased, and secondary dust raising is easy to occur when the filter screen is replaced.
The electrostatic dust collection method is to ionize gas by using an electrostatic field to enable dust particles to be charged to a certain electric property and then to be adsorbed to a collecting electrode with the opposite electric property. Such as (Chinese registered patent application number:). The method can continuously generate ozone to be released into the environment in the working process, the collecting electrode needs to be cleaned regularly, and secondary dust is easy to be blown out in the cleaning process.
The method for releasing high-activity purifying particles to the environment is to release ozone or negative ions to the ambient air to neutralize and agglomerate small-particle-size dust particles into larger particle sizes for sedimentation. Such as (Chinese registered patent application number:). However, such methods inevitably produce ozone released into the vehicle environment during operation.
The above various existing vehicle-mounted air purification systems have their respective disadvantages, such as incomplete purification function, high use cost, generation of solid waste, secondary dust emission, generation of ozone, and the like, due to the inherent properties of their purification principles.
Disclosure of Invention
In order to make up the defects of the prior art, the invention provides a liquid filtration type plasma vehicle-mounted air purification system. The method has wide coverage for purifying the pollutants in the air, and the pollutants which can be purified comprise PM10, PM2.5, bacteria, viruses, formaldehyde and other VOCs. And the solid filter screen is not used, harmful or difficultly treated solid or liquid waste is not generated, the use cost is low, and any harmful gas such as ozone is not generated.
Compared with the prior art, the invention has the following beneficial effects:
1. the purification type is comprehensive, and under the condition that other additional functions (formaldehyde catalyst, ozone catalyst, ultraviolet sterilization, high-temperature sterilization and the like) are not added, the main pollutants, such as PM10, PM2.5, bacteria, viruses, formaldehyde and the like, benzene, ammonia and the like, can be purified at one time by a simple process.
2. No solid filter element is used, and no solid waste is generated. The only consumable is non-toxic and harmless soda powder, and the usage amount is very small, and the cost is low.
3. No harmful gas by-product is discharged, and the ozone pollution risk is avoided after long-term use.
4. The water is used as an adsorbent, and the generated waste water is equivalent to muddy water, is non-toxic and harmless and can be directly discharged out of the vehicle.
5. The parts do not need to be replaced periodically (compared with a filter screen type), and the parts do not need to be cleaned periodically (compared with an electrostatic dust collection type).

The mixed gas from the gas mixing cavity 200 enters the gas washing tank 300, the gas flow passes through the perforated sieve plate 304 in the gas washing tank 300 to become bubbles and enters the gas washing liquid 301, and the decomposition products of large-particle-size dust particles, microorganisms and gaseous organic volatile matters in the gas flow (bubbles) are adsorbed by the gas washing liquid 301. The air flow from the gas washing tank 300 enters the ozone removing tank 400, the electrolysis electrode 402 of the ozone removing tank 400 electrolyzes the ozone removing liquid 401, so that the ozone removing liquid 401 contains hydroxide ions with a certain concentration, the air flow passes through the perforated sieve plate 304 in the ozone removing tank 400 to become bubbles and enters the ozone removing liquid 401, and the hydroxide ions in the ozone removing liquid 401 reduce the ozone in the air flow (bubbles) into oxygen. The air from the ozone removal tank 400 is purified.
Splash guards 602 are provided on the inner walls of the gas washing tank 300, the ozone removing tank 400, and the condensed water tank 503.
