Embodiment 1

[0053] see figure 1 , the water spraying mechanism in the air purification system of the present invention includes a water spraying area 2, a water mist spraying area 3, a water-gas separation device 4, a wind speed sensor 5, a wind pressure sensor 6, The temperature and humidity sensor 7 and the negative ion concentration sensor 8, as well as the water supply and return device 9 and the control unit (not shown) arranged outside the air duct. The water spray area, water mist spray area and water-air separation device are arranged in sequence along the air duct; the wind speed sensor and wind pressure sensor are respectively arranged in the air duct at the front of the mechanism, and the temperature and humidity sensor and the negative ion concentration sensor are respectively arranged at the rear of the mechanism In the air duct; the water supply and return device includes a water supply pipeline and a return water pipeline, which are respectively connected to the water spray...

Embodiment 2

[0062] The control method of the water spray mechanism of the air purification system in this embodiment includes two control modes of maximum water pressure and flow control mode and negative ion concentration control mode. By collecting the air environment quality detection data of the air outlet of the air purification system, the collected The detected air environment quality detection data is compared with the preset switching threshold, and the maximum water pressure and flow control mode and the negative ion concentration control mode are switched according to the comparison result.

[0063] Since the change of the negative ion concentration value is related to the results of the comprehensive changes in the wind speed, nozzle pressure, flow rate, temperature, humidity and other parameters in the air inlet duct, there is no fixed mathematical function model. In this embodiment, wind speed and water spray pressure are used as the main variables for adjustment, and the adj...
