An embodiment of the present invention provides a vehicle body air purification method, and with reference to fig. 1, the method includes: circulating air in the vehicle by using a vehicle body air conditioning system; a low-temperature plasma generating device is arranged on the inner side of an air return opening of the vehicle body air conditioning system, and air entering the air return opening is purified by using low-temperature plasma.
The air purifying method for the vehicle body provides that an air purifying mechanism is integrally arranged at an air return port of the vehicle air conditioning system. The air purification mechanism purifies and degerming the air entering the air return opening, so that the purified fresh and clean air is blown out from the air outlet. The air purification mechanism is integrated at the air return inlet of the vehicle air conditioner, the air in the vehicle can be purified by circulating air generated by the air conditioning system, the vehicle air conditioning system is generally provided with the air return inlet, the number of the air purification mechanism can be reduced, and the centralized purification treatment of the air in the vehicle is facilitated.
The method for purifying the air entering the air return inlet does not affect the installation structure layout of the vehicle body and the vehicle air conditioner, reduces the cost of independently additionally installing the air purifier, improves the air purification treatment capacity on the basis of meeting the regulation function of the ambient temperature of the carriage by the air conditioning system, and keeps the fresh ambient air of the carriage and the health of passengers.
The air purification mechanism can adopt a low-temperature plasma generating device, and air purification is carried out by using low-temperature plasma generated by the low-temperature plasma generating device. Low-temperature plasma sterilization is an advanced technology for blocking germ transmission and purifying air in an air environment, and experimental data prove that bacteria in a growth phase, such as escherichia coli, staphylococcus aureus, micrococcus luteus, bacillus megaterium, bacillus subtilis, bacillus natto and bacillus subtilis dental blistering can be effectively killed in a region directly treated by plasma.
The working principle is that a low-temperature plasma close to room temperature is generated through a dielectric barrier discharge system, most of bacteria passing through a plasma area are broken into fragments by plasma current, and the high-efficiency inactivation of bacteria and fungi in the air can be realized within milliseconds, but radiation and other byproducts are not generated.
The low-temperature plasma generating device is arranged to purify the air in the vehicle by using low-temperature plasma, a large amount of energy-carrying electrons generated by low-temperature plasma medium barrier discharge can bombard pollutant molecules in the air sucked through the air return port to ionize, decompose and excite the pollutant molecules, so that complex molecules are decomposed into simple small-molecule safe substances, toxic and harmful substances are converted into non-toxic, harmless, low-toxicity and low-harmful substances, the pollutant and harmful bacteria are degraded and removed, the air in the vehicle is purified, peculiar smell caused by pollution is eliminated, and the environmental air of the vehicle is kept fresh. The low-temperature plasma generating device has high air purification efficiency and thorough purification effect.
Further, the low-temperature plasma generating device comprises a low-temperature plasma discharging device and a high-frequency pulse power supply, and the low-temperature plasma discharging device is connected with the high-frequency pulse power supply. The low-temperature plasma discharge device generates low-temperature plasma under the excitation of the high-frequency pulse power supply.
On the basis of the above embodiment, further, a vehicle body air purification method further includes: the inside of the return air inlet of the vehicle air conditioning system is provided with a photocatalyst decomposition catalyst, and the photocatalyst is used for purifying air entering the return air inlet. The photocatalyst decomposition catalyst can generate a strong catalytic degradation function under the action of ultraviolet light, can effectively degrade toxic and harmful gases in the air, effectively kill various bacteria, decompose and harmlessly treat toxins released by the bacteria or fungi, and simultaneously has the functions of removing formaldehyde, deodorizing, resisting pollution and purifying the air.
The photocatalyst decomposition catalyst is arranged, so that the purification treatment effect of air entering the air return inlet can be further ensured, the air purification treatment capacity is improved, and the fresh air in the carriage environment and the health of passengers are kept.

On the basis of the above embodiment, further, a vehicle body air purification method further includes: the operation of the low-temperature plasma generating device and the operation of the photocatalyst decomposition catalyst are controlled by utilizing an air conditioning system of the vehicle body. The air conditioning system can comprehensively carry out temperature regulation and air purification regulation. The air purification can be conveniently adjusted, the control structure of the air purification mechanism is reduced, and the internal space of the vehicle body is saved; the air conditioning system can also have the temperature adjusting function and the air purifying function, and the intelligence of the air conditioning system is improved.
On the basis of the above embodiment, further, the controlling the operations of the low-temperature plasma generator and the photocatalyst decomposition catalyst by using the vehicle air conditioning system specifically comprises: collecting air quality parameters inside a carriage; and controlling the operation of the low-temperature plasma generating device and the photocatalyst decomposition catalyst according to the real-time air quality parameters in the carriage.

The first preset value is less than the second preset value. A larger air quality parameter indicates a poorer air quality. The real-time air quality parameter is smaller than the first preset value, namely the air quality is better, and the air purification mechanism does not need to be started at the moment. If the real-time air quality parameter is larger than the first preset value and smaller than or equal to the second preset value, namely the air quality is general, the evaporation fan of the air conditioning system can be started to suck the air in the carriage into the air return inlet, and only the photocatalyst decomposition catalyst can be started to purify the air.

When the air quality of the carriage does not reach the standard, and the specific real-time air quality parameter is located between the first preset value and the second preset value and needs to be subjected to air purification, the fan can be started to operate for preset time according to the first power, the air quality parameter during the operation of the preset time is compared with the first preset value, and if the air quality parameter is still larger than the first preset value at the moment, namely the air quality still does not reach the standard, the operation power of the fan can be increased to operate at the second power.
On the basis of the above embodiment, further, if the real-time air quality parameter is greater than or equal to the second preset value, controlling the fan of the vehicle air conditioning system to operate, and controlling the photocatalyst decomposition catalyst and the low-temperature plasma generating device to operate simultaneously further includes: controlling a fan, a photocatalyst decomposition catalyst and a low-temperature plasma generating device of the vehicle body air conditioning system to run for a preset time; and if the air quality parameter during the operation preset time is greater than the second preset value, increasing the operation power of the fan.
When the air quality of the carriage does not reach the standard, and the specific real-time air quality parameter is larger than or equal to the second preset value and air purification needs to be carried out, the fan can be started firstly to operate for the preset time according to the first power, the air quality parameter during the operation of the preset time is compared with the second preset value, if the air quality parameter is still larger than the second preset value at the moment, namely the air quality still does not reach the standard, the operation power of the fan can be increased to operate at the second power.
