Description

An externally installed fresh air purifier

technical field

The invention relates to an air purification device, in particular to an externally mounted fresh air purifier.

Background technique

At present, the most commonly used indoor air cleaning method is to install an air purifier. The working principle of mainstream air purifiers on the market is to rely on the internal filter to filter the air flowing through it, which belongs to the indoor air circulation purification. Purifiers are not suitable for air cleaning in quiet environments such as conference rooms, classrooms, office halls, etc. The main reasons include: (1) Filter-type air purifiers are noisy. In order to ensure smooth passage of air through the filter, traditional filter-type purification The inside of the purifier needs to be equipped with a ventilation fan with a large air volume to accelerate the flow of air, so the noise of the purifier is often above 65 decibels, and the doors are often opened and closed in the above places, and the air inside and outside is frequently exchanged. Once the high-power purifier is turned on indoors, the noise is very loud, which will seriously damage the quiet environment. (2) The filter screen of the filter-type air purifier needs to be manually cleaned regularly. In the weather environment with severe haze pollution, the above places are dozens of times the rate of indoor pollution in the home, and the filter screen will soon be filled with pollutants. Therefore, the filter should be cleaned every day. If the filter is not cleaned in time, the filter-type purifier will not only fail to purify the air, but also cause secondary pollution, but the cleaning of the filter is more troublesome. Therefore, it is rare to see air purifiers installed in public places such as classrooms, theaters, conference rooms, security posts, reception centers, and office halls. Based on the above reasons, an externally installed fresh air purifier is designed using the principle of high-voltage electrostatic dust collection.

The battery 6 is a rechargeable battery, and a solar panel 26 for charging the battery 6 is installed on one outer wall of the casing 1 , and an advertising board 28 can be installed on the other outer wall of the casing 1 .

The controller 8 of the present invention is preferably a PLC or a single-chip microcomputer. The controller 8 is connected to the municipal power supply and the battery 7, and is set to give priority to the battery 7 for power supply. 8; the heating wire 17 is connected to the controller 8 through a wire; , The second humidity sensor 24, the second air sensor 25, and the wireless transceiver 27 are respectively connected to the controller 8 through wires.

The specific implementation of the above functions is a well-known technology.

Installation method of the present invention: the present invention adopts wall hanging installation, just like installing an air conditioner external unit, the casing 1 is fixed on the outer wall, a through hole is opened on the wall, the water injection pipe 3, the air outlet pipe 10, the water outlet pipe 20 It is a soft pipe. The water injection pipe 3 and the air outlet pipe 10 extend into the room through the through hole of the wall. The air outlet of the air outlet pipe 10 can be placed in the indoor position according to the season or the weather. For example, in winter, the air outlet can be facing the heater. , or wrap the indoor part of the air outlet pipe 10 on the heating, directly heat the incoming cold air, and at the same time accelerate the process of decomposing a very small amount of residual ozone into oxygen; the water outlet pipe 20 extends into the rainwater pipe of the outer wall, and the water outlet pipe 20 The through-hole sealing connection of the lower bottom surface of the casing 1 is realized through the U-shaped valve 19 . According to different occasions of use, the present invention can adopt various ways such as plaque suspension installation, ground support installation and the like. If the installation location is sufficiently illuminated, the solar panel 26 provided on the outer wall of the present invention can charge the battery 7 in the casing 1; if the outer surface of the casing 1 is used as a plaque, a display screen 6 or advertisements are arranged on the outer wall of the casing 1 Card 28.

A small amount of ozone will be generated during the high-voltage electrostatic cleaning process. Ozone is unstable at room temperature and decomposes into oxygen in a few minutes. The ozone filter 9 is installed in the casing 1 to quickly decompose the ozone, and if the purified air is blown toward Heating, if there is a very small amount of residual ozone, it will be decomposed into oxygen immediately under the high temperature of heating.

The working process of fresh air purification is as follows: fill the water tank 2 with water through the water injection pipe 3 from the room, and inject the stock water in the curved pipe of the U-shaped valve 19 in advance, and the stock water will remain in the U-shaped curved pipe for a long time, which can isolate the flow of air inside and outside. The controller 8 controls the high-voltage electrostatic dust collector 16 to energize, generates a high-voltage electrostatic field on the conductive plate, controls the suction fan 23 to work, and the outdoor air is sucked into the casing 1 and flows to the high-voltage electrostatic dust collector through the air duct 22. Under the plate 16, and then flow through the vertically arranged dust collecting plates (conductive flat plates), the pollutant particles in the air are adsorbed to the dust collecting plates in the electrostatic field, and the clean air flows to the upper part of the casing 1, resulting in The trace amount of ozone is decomposed by the ozone filter 9 , and the purified air flows into the room through the blowing fan 11 and the air outlet pipe 10 .

The second humidity sensor 24 realizes the function of detecting the outdoor air humidity. If the outdoor air humidity is too high and exceeds the rated working range of the high-voltage electrostatic dust collector 16, it transmits a signal to the controller 8 and the host stops working.

The second air sensor 25 realizes the function of detecting the outdoor air quality. If the outdoor air quality is good, the controller 8 controls the high-voltage electrostatic dust collector 16 to not work, and directly sends the outdoor clean air into the room; if the air quality is seriously polluted (such as sandstorm) If the rated working range of the high-voltage electrostatic integrated board 16 is exceeded, the host stops working.

The first air sensor 12 realizes the function of detecting the air quality in the casing 1. If the internal air quality does not meet the standard for a long time, the controller 8 determines that the dust collecting plate is seriously dirty and the adsorption capacity is insufficient. At this time, the high-voltage electrostatic dust collecting plate is controlled. 16 Power off, and then control the water pump 4 to supply water to the nozzle 15. At the same time, the nozzle 15 swings and flushes under the drive of the steering gear 13. The water flow washes away the dust adsorbed on the high-voltage electrostatic dust collecting plate 16, and the particle size of the electrostatic adsorption is very small. It is very easy to wash off, the sewage flows to the bottom surface of the casing 1, and flows out through the U-shaped valve 19 and the water outlet pipe 20, and flows away through the rainwater pipe on the wall; the function of the water baffle 21 is to prevent the sewage from flowing to the suction fan 23, and there is always water in the U-shaped valve 19 to prevent the inhaled air from flowing out from here.

The first humidity sensor 18 realizes the humidity detection of the high-voltage electrostatic dust-collecting plate 16, and can only work if its surface humidity is within the rated working range. If the humidity of the dust-collecting plate exceeds the standard, the electric heating wire 17 is controlled to be energized and heated to dry the dust-collecting plate. .

The water inlet of the water injection pipe 3 is normally placed in the room, and only when the water tank 2 is short of water, the water tank is filled with water through the water injection pipe 3 from the room.

The fresh air purification process can be performed manually or automatically by setting the detection value.
