Description

Air purification system

The present invention relates to an air purification system, and more particularly, a decentralized small-scale air capable of intensively managing a place where pollutants such as VOC, odor, and fine dust are generated while a reduction device moves along a rail installed on the ceiling. It relates to a purification system.

In addition, a plurality of length-controlled, movable variable pipes with sensors mounted on the ceiling or wall are installed, and air is introduced and discharged through the pipes to efficiently clean the place where air pollutants are generated, and indoor air pollution. The present invention relates to an air purification system using a plurality of variable pipes capable of managing indoor air quality based on material resolution.

VOCs (Volatile Organic Compounds) refer to liquid or gaseous organic compounds that are easily evaporated into the atmosphere due to high vapor pressure, and they refer to substances that cause photochemical smog by generating photochemical oxidizing substances such as ozone by causing a photochemical reaction in the atmosphere. Particulate matter (PM), which exists as particles in the air, is a primary carcinogen and is a major substance of fine dust. In addition, nitrogen oxides (NOx), ammonia (NH3) and sulfur compounds (SOx, other sulfur-containing gases) are also major air pollutants that are carcinogenic or odorous, and are representative precursors of (ultra) fine dust. It is well known as.

When the concentration of VOC or fine dust indoors is high or when there is an odor, ventilation is usually opened by opening a window or door, but it is not easy to ventilate at home because the concentration of fine dust outdoors is also high recently, and in the case of businesses or factories, windows are opened. It is not easy to ventilate by opening the door.

For this reason, the demand for air purifiers has recently increased. An air purifier is a device that filters foreign substances in the inhaled air. It absorbs the entire indoor air, and after a filter installed inside removes foreign substances, clean air is supplied back to the room. Since the air purifier inhales the entire indoor air to remove foreign matter, there is a problem in that it consumes a lot of power because it inhales the entire indoor air even when VOC is generated in a specific space within the space.

In addition, the larger the space area, the larger the size of the air purifier must be, and there are cases where several air purifiers must be installed. In particular, if the space is separated by a partition wall, an air purifier must be moved and used or must be provided in each spaced division. Recently, when VOC, fine dust, or odor is detected by a sensor, the air purifier moves to the corresponding space to purify the air. However, since air purifiers are generally located on the floor, it is difficult to move to the corresponding space if there is an obstacle preventing the movement of the air purifier on the floor, and the space utilization is not high because it occupies the user's work space and moves. There is a problem.

19 is a diagram illustrating an operation of a unit flow path of an air purification system according to a second embodiment of the present invention. As shown in FIG. 19, when air pollutants are distributed in a specific area, and the fixed sensor 200 installed on the wall detects this and transmits a detection signal to the control unit 300, the ventilation port 140 is sent to the control unit 300. By adjusting the height and moving down. Air pollutants are sucked from the unit pipe 141 located at the bottom, and the sucked air pollutants are discharged to the outside through the unit flow path 110 after moving along the plurality of unit pipes 141. At this time, it is preferable that at least one additional detection sensor 142 is installed on the outer surface of the unit pipe 141 positioned at the bottom, that is, the unit pipe 141 positioned at the outermost side of the ventilation port 140.

The additional detection sensor 142 is located in the corresponding area, absorbs and removes the air pollutant, and then functions to additionally detect the concentration of the air pollutant in the surrounding area of the corresponding area. The surrounding area is additionally detected, and when air pollutants are detected, they are additionally sucked to remove air pollutants, and when air pollutants are detected, return to the original position. That is, the additional detection sensor 142 is characterized in that the control unit 300 controls whether the ventilation port 140 is additionally operated by transmitting a signal to the control unit 300. At this time, the plurality of unit pipes 141 constituting the ventilation port 140 are installed so as to be rotatable with respect to the unit pipes 141 in contact with each other, thereby improving detection accuracy.

In addition, the additional detection sensor 142 may be installed to detect the position of the fixed sensor 200.

At this time, it is preferable that the unit pipe 141 is formed in a shape whose diameter decreases as the length is adjusted to the lower side and moves. As the diameter of the unit pipe 141 increases, the load applied to the lower portion increases, so if the unit is rotated while adjusting the angle, it is not easy to rotate, but if the diameter decreases as it moves downward, the diameter is relatively reduced. The unit pipe 141 located in the large upper portion is supported and the unit pipe 141 having a small diameter located at the lowermost end rotates along the trajectory, thereby effectively purifying and managing the air in the corresponding space.

23 is a flowchart illustrating an air purification method using an air purification system according to a modified example of the second embodiment of the present invention. As illustrated in FIG. 23, after the first reduction step S300, an additional sensing step S400 may be further performed. As described above with reference to FIG. 19, at least one additional detection sensor 142 may be further installed on the outer surface of the unit pipe 141 located at the outermost of the unit pipes 141 constituting the ventilation port 140. . After the first reduction step S300, an additional detection step S400 in which the additional detection sensor 142 detects whether air pollutants remain in the surrounding area of the corresponding area is further performed. When the additional detection sensor 142 detects that the air pollutant concentration is equal to or higher than a preset value, a second reduction step (S500) of additionally inhaling and removing the air pollutant by transmitting a detection signal to the control unit 300 proceeds.
