Purification techniques are largely classified into physical filtration and chemical adsorption or decomposition techniques, wherein physical filtration is classified into media filtration and electrostatic precipitation. In the above purification modes, although the filtration efficiency of the medium filtration can reach high, on one hand, the wind resistance is high, on the other hand, the medium filtration needs to be replaced regularly, the replacement cost is high, and the medium filtration has no purification effect on harmful gases, bacteria, viruses and the like; although the electrostatic dust collection has small wind resistance and can purify bacteria and viruses, the filtering efficiency of particulate matters is low, and the dust collection part needs to be cleaned by professionals at regular intervals; although the chemical adsorption technology can treat part of harmful gas, the purification effect on particulate matters is poor, and the adsorbent needs to be periodically regenerated and desorbed; chemical decomposition techniques can catalytically decompose harmful gases and bacterial viruses into substances harmless to humans (such as water and carbon dioxide, etc.), but have no purifying effect on particulate matter.

The box 316 has an air inlet 315 on one side and an air outlet 313 on the opposite side. PM2.5 concentration sensors are arranged on the air inlet and the air outlet 315 and 313. A double layer metal filter mesh 312 covers the air inlet 315. A bypass duct 314 with an air valve at the inlet is in communication with the tank 316 and is positioned adjacent to the air inlet 315.

Still further, the housing 316 is mounted to the base frame 302.
The integrated ion waterfall purifies, self-cleaning function in the use process of concentrated fresh air handling machine of an organic whole as follows:
Outdoor fresh air enters the shell 15 through the fresh air inlet 2, enters the air inlet 315 of the ion waterfall purifying device 3, passes through the double-layer metal filter screen 312 arranged in the ion waterfall purifying device 3 in front to prevent large-particle dust particles, flocks and the like from entering the ion waterfall purifying device 3 to cause breakdown faults. Then, air is purified by the two-stage ion waterfall purification modules 304 and 306 and flows to the plate type heat recovery section through the air outlet 313 of the ion waterfall device, after the heat in the exhaust air is recovered through the plate type heat recovery core 4 (precooling in summer and preheating in winter), the temperature and the humidity are regulated through the double-cold-source dehumidification coil/heating coil 12 (cooling and dehumidifying in summer and heating in winter), then the air is reheated to a more comfortable temperature (only started in summer) through the reheater 11 by utilizing the condensation heat generated by partial dehumidification, and then the air is humidified through the humidifier 10 (only started in winter) and then is sent into a room through the blower 9. The indoor return air is sucked into the shell 15 from the return air inlet 7 by the exhaust fan 6, and after heat exchange and purification are carried out between the plate-type heat recovery core 4 and fresh air, the residual condensation heat generated by dehumidification is taken away and discharged outdoors through the exhaust outlet 1 when passing through the heat dissipation condenser 14 (only used in summer).
When the PM2.5 concentration sensor at the air outlet 313 of the ion waterfall purifying device 3 detects that the PM2.5 concentration in the purified air is higher than the set value C mp2.5 1 for a period of time, the air valve at the inlet of the bypass air path 314 in the ion waterfall purifying device 3 is changed from fully closed to fully opened, and the air resistance of the air path of the ion waterfall purifying module is larger than that of the bypass air path, so that most fresh air directly passes through the purifying device through the bypass air path. At this time, both of the two-stage ion waterfall purification modules 304, 306 stop the power supply operation. At the same time, the purification device starts a self-cleaning state, pressurized tap water flows into the three-stage cleaning devices 303, 305 and 307 through the connecting pipelines, the cleaning and purifying module is sprayed out from the cleaning spray 311 at high pressure, the spray is controlled to move along a set route through the cleaning spray position control device (in the embodiment, the cleaning spray with the position control device is marked by the reference numeral 311), and each area of the whole ion waterfall purification device 3 is ensured to be cleaned, and cleaning water flows into the bottom water receiving disc and is discharged out of the box 316 from the water outlet. After the cleaning is completed, the drying fan 310 and the electric heater 309 are started, air sucked from the machine room is heated by the electric heater 309 and then is sent into the ion waterfall purifying device 3, the ion waterfall purifying device 3 is dried, and the air with water vapor is discharged into the machine room through the drying air outlet 301 until the temperature and humidity sensor 308 arranged in the purifying device detects that the temperature and humidity in the device reach a drying target set value. After the drying is finished, the two-stage ion waterfall purifying modules 304 and 306 resume power supply operation, the air valve of the air inlet of the bypass air passage 314 is closed, and the air is still purified by the ion waterfall purifying device 3.
Because the ion waterfall purifying device 3 can not be electrified to purify during the cleaning period, the cleaning time is selected when the PM2.5 concentration sensor of the air inlet 315 of the purifying device detects that the PM2.5 concentration of the fresh air is lower than the set value Cmp 2.5 2 for a period of time, so that the polluted air is prevented from being directly sent into a room without purification.
Above-mentioned integrated ion waterfall purifies and self-cleaning function in concentrated fresh air handling machine of an organic whole has following characteristics:
1. The bypass air passage with the electric air valve is added in the ion waterfall purifying device, so that the air supply of the equipment is not influenced when the ion waterfall is cleaned.
2. In order to avoid that polluted air enters the room from the bypass air path without being purified when the ion waterfall purification module is cleaned, the control system needs to select the cleaning time. Namely: when the PM2.5 concentration at the air outlet of the purification device is detected to exceed the set value C mp2.5 1 for a period of time, the cleaning parameter A arranged in the system is changed from 0 to 1, when the PM2.5 concentration at the air inlet of the purification device is detected to be lower than the set value C mp2.52 for a period of time, the cleaning parameter A arranged in the system is changed from 1 to 2, and the ion waterfall purification device enters a cleaning state only when the cleaning parameter A is 2. After the cleaning and drying are completed, the cleaning parameters are restored to 0.
3. After the centralized fresh air processor is started, no matter in a cleaning state or a running state, two modes of manual operation and automatic operation are selected. In the automatic mode, the operation state of the purification device is automatically adjusted according to the detection data of a PM2.5 concentration sensor and a temperature and humidity sensor which are installed in the device.
The integrated ion waterfall purifies and self-cleaning function in concentrated fresh air handling machine of an organic whole that this embodiment provided, it can all have higher filtration efficiency to the particulate matter of various particle diameters in the air, and can with the most common harmful gas in the air and bacterial virus ionization purification, windage is little, no consumptive material, need not maintain (self-cleaning), can satisfy concentrated air conditioning system and to all demands of fresh air handling.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the invention, which is defined by the appended claims.
