Description

TECHNICAL FIELD

[0001] The present application relates to the field of air purification, in particular to a temperature difference driven air purification system. BACKGROUND

[0002] At present, due to the poor air circulation, high population density and strong mobility in the closed passenger stations, airports and public transportation waiting rooms in transportation hubs, the indoor air quality deteriorates, bacteria and viruses flow with the air, and if air treatment is not timely and effective, it is easy to cause cross-infection of viruses, unpleasant odor generated by the interaction of bacteria and human sweat, and other problems, affecting people's health and travel quality.

[0003] The central air conditioning system currently used is mainly installed on the roof of the transportation hub building, and the roof is far away from the crowd, and the indoor space of the transportation hub building is spacious, the population is dense and the mobility is strong, so the central air conditioning needs to be continuously supplied with cold air to maintain the comfortable temperature of the human body. The cold air is difficult to persist in the near ground, and the central air conditioning sensor always gets a signal higher than the minimum starting value, so the central air conditioning runs continuously, and the power consumption is high.

[0004] The existing air purification treatment methods for indoor air are various, which can be roughly divided into adsorption, ultraviolet lamp irradiation, photocatalyst, negative ion and plasma method, and composite method according to the basic principle. However, adsorption cannot treat gaseous substances, ultraviolet lamp needs to be irradiated for half an hour to disinfect and sterilize and produce too much ozone; the photocatalyst method has extremely low purification efficiency and produces toxic intermediates in the photocatalytic process; the negative ion and plasma method and the composite method make the particles in the air charged and gather to form larger particles, which are settled, but the particles are not actually removed, which is easy to cause dust again, and the high-voltage ion technology produces ozone and other by-products in the working process.

[0005] Ozone is a highly efficient sterilization and detoxification oxidant, but it may also harm the human body while killing viruses and bacteria, kill white blood cells, accelerate the aging of the surface of objects, and have the risk of causing cancer. Ozone needs to be treated for 30 minutes to restore to oxygen, and personnel need to avoid during ozone production and use.

DETAILED DESCRIPTION

[0038] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below in conjunction with the drawings.

[0039] Please refer to Figures 1-11 , the application provides a temperature difference driven air purification system, comprising the following steps:

[0040] S1, air inlets one 01 and two 02 are arranged above the indoor surface, air inlets three 03 and four 04 are arranged below the indoor surface, air inlets one 01 and three 03 are located on the same side of the indoor, air inlets two 02 and four 04 are located on the same side of the indoor, a central air conditioner 05 is arranged above the indoor, and the indoor air is maintained at a comfortable temperature for human body by the central air conditioner 05 , the outdoor air temperature is recorded as ;

[0041] S2, when the indoor air is circulated, at this time, air inlets one 01 and two 02 and air inlets three 03 and four 04 are connected with the air purification device 10;

[0042] S3, start the central air conditioner 05, if the indoor air temperature is lower than the outdoor temperature (the central air conditioner blows cold air), that is less than , the indoor air density increases, the volume shrinks, and a sinking air flow is formed, which forms a high pressure area at the bottom of the room. While the sinking air cools down, the surrounding hot air replaces the cooled air and forms an ascending air flow, which forms a low pressure area at the top of the room. The indoor air enters the air purification device 10 through the air inlets 3 and 4, and the purified air enters the room through the air inlets 1 and 2, completing the circulation and purification of the indoor air.

[0043] S4, if the indoor air temperature is higher than the outdoor temperature (the central air conditioner blows warm air), that is, greater than , the warm air density decreases and accumulates at the upper layer of the room, forming a high pressure area. The gas pressure above the neutral plane in the room is greater than the gas pressure at the same height outside, and the indoor air enters the air purification device 10 through the air inlets 1 and 2, and the purified air enters the room through the air inlets 3 and 4, completing the circulation and purification of the indoor air.

[0044] S5, when the indoor air is circulated, the air inlets 1 and 2 and the air inlets 3 and 4 are connected to the outside air. When the high pressure area is formed at the bottom of the room and the low pressure area is formed at the top of the room, the high pressure area at the bottom of the room is exhausted through the air inlets 3 and 4, and the low pressure area at the top of the room is inhaled through the air inlets 1 and 2, thereby automatically driving the air flow in and out of the room through the temperature difference.

[0045] In the above technical solution, the neutral plane refers to the plane with zero excess pressure, and the excess pressure is the pressure difference between the air inlet and the air outlet. When the excess pressure is zero, the plane is the neutral plane.

[0046] In summer, when the indoor air is circulated, the sinking cold air in the room enters the air purification device 10 through the air inlets 3 and 4, and the purified cold air is discharged to the upper layer of the room through the air inlets 1 and 2. The cold air can accumulate in the upper layer of the room, preventing the sensor of the central air conditioner 05 from always receiving a signal higher than the minimum starting value due to the sinking of the cold air, avoiding the continuous operation of the central air conditioner 05, and reducing the power consumption.

[0047] In winter, when the indoor air is circulated, the warm air blown by the central air conditioner 05 is reduced in density and accumulated in the upper layer of the room, forming a high-pressure area. The warm air in the upper layer of the room enters the air purification device 10 through air outlets one 01 and two 02, and the purified warm air is discharged to the lower layer of the room through air outlets three 03 and four 04, avoiding the accumulation of warm air in the upper layer of the room, which leads to a large temperature difference between the upper and lower layers of the room. The warm air can be evenly dispersed, improving the suitability of the indoor environment.

[0048] It should be noted that when the indoor air is circulated, the indoor and outdoor air can be effectively circulated, and the circulating air can continuously introduce fresh outdoor air into the room, replacing the dirty air that may exist in the room. Indoor air circulation is mainly used in cases where the indoor and outdoor temperature difference is small, reducing the loss of indoor heat and reducing the energy consumption of the indoor central air conditioner 05. When the indoor air is circulated, the cold air or warm air in the room does not come into contact with the outside air, reducing the energy consumption of the central air conditioner 05 and optimizing the energy use efficiency.

A cavity one is provided between the upper end of the purification mechanism 12 and the sealing plate 13, and a cavity two is provided between the lower end of the purification mechanism 12 and the sealing plate 13. Four connecting pipes 14 are installed on the outside of the purification housing 11, which are symmetrically arranged on the left and right sides of the purification housing 11. The connecting pipe 14 located on the upper end of the outside of the purification housing 11 is connected to the cavity one, and the connecting pipe 14 located on the lower end of the outside of the purification housing 11 is connected to the cavity two.

[0050] In the above technical solution, the cavity one is connected to the air outlets one 01 and two 02, and the cavity two is connected to the air outlets three 03 and four 04. When the indoor air flows from the cavity one to the cavity two, a negative pressure suction is generated in the cavity two. When the indoor air flows from the cavity two to the cavity one, a negative pressure suction is generated in the cavity one. The purification mechanism 12 can effectively filter and purify the indoor air, so that impurities, suspended particles and harmful bacteria in the air can be effectively removed, preventing respiratory diseases caused by poor indoor air circulation and avoiding negative effects on the health and comfort of indoor personnel.

[0054] Referring to Figure 6 As shown in the preferred technical solution of the embodiment, the filtering unit 122 comprises an inner annular frame 1221, an outer annular frame 1222, a partition plate 1223 and a filtering frame 1224, the middle of the annular cavity is provided with the inner annular frame 1221, the upper and lower ends of the inner annular frame 1221 are connected with the cleaning unit 123 through bearings, the outer side of the inner annular frame 1221 is provided with the outer annular frame 1222, the partition plates 1223 are uniformly installed between the inner annular frame 1221 and the outer annular frame 1222, the adjacent partition plates 1223 are provided with fan-shaped cavities, and the filtering frames 1224 are installed in the fan-shaped cavities.

[0057] In the above technical solution, the activated carbon adsorber 103 is arranged in the middle, and the HEPA filter 102 and the pre-filter 101 are arranged on both sides of the activated carbon adsorber 103, so that the filter frame 1224 can accurately filter the air no matter whether the indoor air flows from cavity one to cavity two or from cavity two to cavity one.

[0058] It should be noted that the pre-filter 101 is used to filter large particles and other substances in the air; the HEPA filter 102 is used to filter air suspended matter, pollen, animal hair and the like; and the activated carbon adsorber 103 is used to adsorb standard cigarette smoke dust, coal dust, formaldehyde, ammonia, benzene, toxic gas, odor and the like.

[0060] In the technical scheme, the cleaning frame 1232 is in sealing connection with the partition plate 1223, and the size of the cleaning frame 1232 corresponds to the fan-shaped cavity, so that a closed space is formed between the inside of the fan-shaped cavity and the inside of the cleaning frame 1232. When the indoor air enters the inside of the cavity two from the cavity one, the upper end surface of the filter frame 1224 filters the indoor air. At this time, the cleaning frame 1232 located on the upper layer of the filter frame 1224 can clean the upper surface of the filter frame 1224, and the cleaning frame 1232 located on the lower layer of the filter frame 1224 can blow back the lower surface of the filter frame 1224, so that the impurities accumulated on the upper layer of the filter frame 1224 can be effectively cleaned. When the indoor air enters the inside of the cavity one from the cavity two, the lower end surface of the filter frame 1224 filters the indoor air.
