Description

Air tour system having multi-functions}

The present invention relates to a multifunctional air tower system, and more particularly, to a function of spraying water mist, a function of sterilizing harmful bacteria contained in the surrounding air and removing fine dust, a function of spraying a sterilizing disinfectant solution mist, and a function of distancing. It relates to a multi-functional air tower system capable of performing a function of marking a road surface in a selective combination.

In recent years, as climate change has intensified all over the world, the surface temperature is rising, and abnormal weather phenomena such as heat waves are frequently occurring in many parts of the world. In general, densely populated urban areas exhibit higher urban heat islands compared to surrounding areas. Urban areas that exhibit the heat island phenomenon are inevitably more vulnerable to temperature rises due to climate change, and due to their dense population, abnormal temperature rises such as heat waves can seriously affect public health and cause large-scale damage. have.

In order to partially solve the heat island phenomenon, a cooling system that installs a spray nozzle at or near a customer attraction facility and lowers the ambient air temperature through spray from the spray nozzle has been adopted.

For example, Korean Patent Registration No. 10-1376331 discloses that n spray nozzles equipped with solenoid valves are grouped and assigned to a cell area in which the entire outdoor space with an open space is separated into cells, and the temperature and humidity of each cell area are assigned. A spray cooling system using different temperatures for each cell region capable of enabling cooling operation of water spray for each cell region through corresponding control for each region is disclosed.

Republic of Korea Patent Registration No. 10-1408655 is installed in an outdoor building with an open space, and configures a spray cooling system that enables outdoor cooling by vaporization through water spray in the form of mist particles, A spray cooling system using variable control of temperature and humidity in which spray pressure and amount of spray can be variably controlled according to measured values of temperature and humidity, rather than a simple operation driving method, is disclosed.

Korean Patent Registration No. 10-1430107 discloses a check valve that operates (on) only at 20 bar or more in a spray nozzle installed in a pipe, so that the residual pressure filled in the pipe line can be treated when the spray is stopped after the water spray operation. When the time delay occurs while lowering the pressure of the entire pipeline through the pressure relief pipe, the water drop prevention function due to the residual pressure of the nozzle can be performed while the nozzle of the injection nozzle is blocked through the check valve. A spray cooling system with

However, the conventional techniques described above are for lowering the ambient temperature in order to partially alleviate the heat island phenomenon that occurs in the summer, and the effect of the spray system in a state where the surrounding air is heavily polluted by causes such as fine dust. It was difficult to expect

On the other hand, Korean Patent Publication No. 10-2018-0080803 discloses that outdoor air purification systems are installed on vertical structures (street lights, telephone poles, traffic facilities) installed along roadsides, and hundreds of thousands to millions of them are operated simultaneously throughout the city, An outdoor air purification system around a road for removing outdoor fine dust and pollutants capable of actively removing fine dust and pollutants in the air is disclosed.

However, since the purification capacity of one such outdoor air purifying system is not large, it is difficult to solve serious air pollution problems only when hundreds of thousands of air purifying systems are simultaneously operated.

In addition, in a situation where Corona 19 is widely spread, complex products that provide various quarantine-related functions for pedestrians according to pedestrian situations are still insignificant.
