It is a cross-sectional view of a clean system.

The moss-based urban air cleaning system 100A according to an embodiment of the present invention is installed in an air circulation element in a city center such as a road or roadside with heavy traffic, and purifies the city air through a moss filter and then discharges it to the outside again. It is characterized by improving the air quality.

The moss-based urban air cleaning system 100A according to the present embodiment includes a main body 110, a moisture supply unit 120, a moss filter unit 130, an air circulation unit, and a fog generating unit 150.

The main body 110 may have a hollow shape and a cylindrical shape with an open top. Although it is illustrated in the drawings as having a cylindrical shape, this is only an example, and it is needless to say that it may have a polygonal polygonal shape having a polygonal cross section if necessary.

The side wall of the main body 110 may be made of a mesh network 115. It is composed of a number of meshes, so that the outside air can flow in smoothly.

A moss filter unit 130 is installed outside the sidewall of the main body 110. The moss filter unit 130 is a filter in which moss is grown on the surface, has a structure attached in a side attachment form, and can sufficiently contact outside air flowing into the main body 110. Moss can relieve stress due to the occurrence of phytoncide, antibacterial effect, deodorant effect, sedative effect, improvement of allergies and skin diseases, has excellent trace metal adsorption ability, carbon fixation amount is 10 times or more of ordinary plants, and oxygen generation It is characterized by its ability to be 10 times higher than that of ordinary plants.

An air circulation unit is installed at the center of the main body 110. The air circulation part includes an upper fan 141 and a lower fan 143.

The upper fan 141 is installed at the height of the upper opening of the main body 110, and the lower fan 143 is installed at the middle height of the main body 110. The inner space of the main body 110 may be divided into a lower space A and an upper space B by the lower fan 143.

The upper fan 141 rotates around the upper shaft 147, and the lower fan 143 rotates around the lower shaft 145. The upper shaft 147 and the lower shaft 145 may be interconnected by gears 146.

A driving part (not shown) is connected to the lower shaft 145, so that the lower fan 143 rotates by rotating the lower shaft 145 by the driving part. And when the upper shaft 147 is connected to the lower shaft 145 through the gear 146, the upper fan 141 is also rotated. If the upper shaft 147 is not connected to the lower shaft 145, only the lower fan 143 can be driven alone to rotate.

When the lower fan 143 is rotated, the air in the lower space A is raised. Due to this, a negative pressure is generated in the lower space A, and external air can be introduced through the outer wall of the main body 110 made of the mesh network 115. The inflowing outside air passes through the moss filter unit 130 installed on the outer wall of the main body 110, and air can be purified in this process. The air raised in the lower space A and positioned in the upper space B may be discharged to the outside through the upper opening of the main body 110. In this case, if the upper fan 141 is rotating, air can be smoothly discharged.

When the upper fan 141 also rotates, the air in the upper space B also rises. As a result, negative pressure is also generated in the upper space B, and external air can be introduced through the outer wall of the main body 110 made of the mesh network 115. The inflowing outside air passes through the moss filter unit 130 installed on the outer wall of the main body 110, and air can be purified in this process.

The purified air may be discharged to the outside through the upper opening of the main body 110.

When the upper fan 141 does not rotate, positive pressure is uniformly generated in the upper space B due to the air raised in the lower space A, and thus air located in the upper space B is main It may be discharged to the outside through the mesh network 115 of the outer wall of the body 110 and the moss filter unit 130 of the outside. In this case, the air in the main body 110 is the primary purified air passing through the moss filter unit 130, and secondly purified by being passed through the moss filter unit 130 to be discharged to the outside in a cleaner state. You can.

Driving of the upper fan 141 and the lower fan 143 may be individually controlled according to the air condition of the downtown area where the system is installed. For example, when the air pollution near the ground surface is severe due to a large number of vehicle operations, primary air purification is performed by the moss filter unit 130 when it enters the lower space (A) by driving only the lower fan (143). When discharged from the space (B) to the outside, the second air purification may be performed by passing the moss filter unit 130 once again.

A gear 146 is interposed between the upper shaft 147 and the lower shaft 145. The upper shaft 147 and the lower shaft 145 may be interconnected by the gear 146, and the rotational force of the lower shaft 145 is transmitted to the upper shaft 147. At this time, depending on the gear ratio (gear ratio) of the gear 146, the upper shaft 147 may have the same or different rotational speed from the lower shaft 145. Through this, it is possible to control the air flow in the main body (110).

A moisture supply unit 120 may be installed under the main body 110. The inside of the water supply unit 120 may be empty, and a predetermined amount of water may be accommodated therein. An external pipe is connected to the moisture supply unit 120 to receive a sufficient amount of moisture from the outside.

A pipe 121 may be vertically coupled to the moisture supply unit 120. The lower end of the pipe 121 is connected to the moisture supply unit 120 and may be elongated along the inner surface of the main body 110 to extend upward. The upper end of the pipe 121 may be connected to the fog generating unit 150, which will be described later. That is, moisture stored in the moisture supply unit 120 through the pipe 121 may be transferred to the fog generator 150. A pump (not shown) may be used when transferring water through the pipe 121.

The fog generating unit 150 is installed around the upper outer periphery of the main body 110, and may have an empty ring shape inside. The fog generating unit 150 may receive moisture from the moisture supply unit 120 through the pipe 121.

A spray nozzle (not shown) is installed on the lower surface or the inner surface of the fog generator 150 to generate mist by spraying moisture therein. The fog generated by the fog generator 150 descends due to its own weight. In addition, while staying on the moss filter unit 130 in the descending process, moss can be supplied with moisture to help the growth of moss. The generation of fog may be performed at regular time intervals (eg, once a day).

When the fog occurs, the upper fan 141 and/or the lower fan 143 is driven to allow outside air to flow into the main body 110, so that the fog generated by the fog generating unit 150 is not scattered outside. While staying on the moss filter unit 130 for a long time, sufficient moisture can be supplied to the moss. In this case, the rotational speed of the upper fan 141 and/or the lower fan 143 may be sufficient if the speed is such that fog is not scattered.

The control unit (not shown) may control operations such as the driving unit and the fog generating unit 150. The control unit may be installed on the main body 110 in the form of a control panel.

The moss-based urban air cleaning system 100A according to the present embodiment may further include an urban environment sensing unit (not shown). Measures one or more urban environment data of temperature, humidity, illuminance, carbon dioxide concentration, and amount of fine dust in the downtown area where the system is installed. To this end, at least one of a temperature sensor, an illuminance sensor, a carbon dioxide sensor, and a fine dust sensor may be installed at a predetermined location.

The control unit may control the operation of each component based on the urban environment data measured by the urban environment sensing unit.

In this embodiment, the moss filter unit 130 may include a plurality of moss filter modules 130a that are mutually coupled. The moss filter module 130a is a wall structure having a shape corresponding to a sidewall of the main body 110, and is connected to a neighboring other moss filter module to entirely surround the outer wall of the main body 110.

4 is a perspective view of a moss-based urban air cleaning system according to another embodiment of the present invention, and FIG. 5 is a perspective view of a moss-based urban air cleaning system when there is one fog generating module according to another embodiment of the present invention. .

In the case of the moss-based urban air cleaning system 100B according to another embodiment of the present invention, when compared to the moss-based urban air cleaning system 100A illustrated in FIG. 1, there is a difference in the configuration and function of the fog generating unit 150 We will focus on this.

The fog generating unit 150 includes a plurality of fog generating modules 150a.

The fog generating module 150a has a shape corresponding to a portion of the ring having a predetermined center angle. In this embodiment, the fog generating module 150a has a structure that can be elevated along the outer wall of the main body 110. Although not shown in the drawing, a guide rail for lifting of the fog generating module 150a may be formed on the main body 110.

The fog generating module 150a may generate fog on the inside, that is, the moss filter unit 130 attached to the outer wall of the main body 110 while moving up and down. Through this, it is possible to reliably keep the fog evenly over the whole of the moss filter unit 130 in the case of a descent due to the self-weight of the fog, so that sufficient moisture is supplied to the moss of the moss filter unit 130 to grow the moss. Can help.

The fog generating module 150a may be independently driven from other fog generating modules. As shown in the figure, only one of the fog generating modules 150a may descend independently to generate fog.

In this embodiment, the fog generating module 150a may have a quantity and arrangement corresponding to each of the moss filter modules 130a constituting the moss filter unit 130. That is, one of the fog generating modules 150a may be responsible for one of the moss filter modules 130a, while ascending and descending along the surface of the corresponding moss filter module 130a, responsible for the growth of the moss.

The controller may individually control the operation of the fog generating module 150a according to the external wall conditions.

The moss filter unit 130 covers the entire 360 degree, and thus, a portion in which sunlight is shining and a portion in which sunlight is not can be distinguished at any point in time. Areas with sunlight can dry more easily than areas with no sunlight.

Also, when the wind blows, the part that directly hits the wind can be dried more easily than the part that does not.

The control unit individually operates the fog generating module 150a corresponding to the moss filter module 130a, which is judged to be relatively dry depending on the external wall conditions such as sunlight irradiation direction, wind direction, and the like, so that more fog spraying is performed, thereby sufficiently supplying moisture. Can be done.

In the above description, the case where there is a fog generating module 150a matched for each moss filter module 130a has been mainly described.

However, in the moss-based urban air cleaning system 100C according to another embodiment of the present invention illustrated in FIG. 5, the fog generating unit 150 may include only one fog generating module 150b. In this case, the fog generating module 150b is implemented to be rotatable along the upper circumference of the main body 110.

The control unit rotates the fog generating module 150b to the position of the moss filter module 130a, which is judged to be relatively dry according to the external wall conditions, and then generates the fog while elevating the fog generating module 150b so that the module has sufficient moisture. Can be supplied.

In this embodiment, the fog generating module 150b has a position where the pipe 121 is disposed as a basic position, and is normally located at a basic position. This is to receive water from the water supply unit 120 through the pipe 121.

Subsequently, when the moss filter module 130a to generate fog is determined according to the external wall condition, it rotates along the upper circumference of the main body 110 under the control of the control unit, and generates fog while performing an elevating operation at the corresponding module position. Is ordered.

When the moss-based urban air cleaning system 100A, 100B, 100C according to the present embodiments is intensively installed in an air circulation element of a poor city, the air quality of the city can be purified through large-scale moss. It functions as a large-capacity air purifier that improves.

It serves as a substitute for street trees planted in downtown areas, and improves health and productivity by improving the aesthetic and mental stability of residents and passers-by, easing stress, and improving the environment by purifying the air by recording the outer wall surface by a moss filter installed on the outer wall. Can be improved.

Although described above with reference to embodiments of the present invention, those skilled in the art variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. And can be changed.
