Description

Multi-function air tower system {Air tour system having multi-functions}

The present invention relates to a multifunctional air tower system, and more particularly, a function of spraying water mist, a function of sterilizing harmful bacteria and removing fine dust contained in the surrounding air, a function of spraying a sterilizing disinfectant mist, It relates to a multifunctional air tower system that can perform a function to mark the road surface in a selective combination.

In recent years, as climate change is intensifying around the world, the surface temperature is rising, and abnormal climates such as heat waves are occurring frequently in many parts of the world. In general, an urban area with a dense population exhibits an urban heat island phenomenon, where the temperature is higher than that of the surrounding area. Urban areas with such a heat island phenomenon are inevitably more vulnerable to temperature rise due to climate change. there is.

In order to partially solve this heat island phenomenon, a cooling system that installs a spray nozzle at a facility or near the facility and lowers the ambient temperature through spraying from the spray nozzle is being adopted.

For example, in Korean Patent Registration No. 10-1376331, n spray nozzles with solenoid valves are bundled and assigned to a cell area in which the entire outdoor space with open space is separated by cell unit, and the temperature and humidity of each cell area are assigned. A spray cooling system using different temperatures for each cell area is described, which can enable cooling driving of water spray for each cell area through a corresponding zone-by-zone control.

Korean Patent No. 10-1408655 describes a spray cooling system that is installed in an outdoor building with an open space and 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 spray amount can be variably controlled according to measured values of temperature and humidity rather than a simple operation driving method is disclosed.

In Republic of Korea Patent Publication No. 10-1430107, a check valve that operates only at 20 bar or higher is configured in the spray nozzle installed in the pipe, so that the residual pressure in the pipe line can be treated when the spray stops after the water spray operation. When the pressure of the entire pipeline is lowered through the pressure release pipeline, and the time delay occurs below 20 bar, the spray nozzle of the spray nozzle is blocked through the check valve, and the residual pressure of the nozzle prevents water dripping due to the residual pressure. 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 summer. It was difficult to expect

On the other hand, in Republic of Korea Patent Publication No. 10-2018-0080803, by installing an outdoor air purification system in vertical structures (street lights, telephone poles, traffic facilities) installed on the roadside, and operating hundreds of thousands to millions of units simultaneously throughout the city, An outdoor air purification system for outdoor use around roads for removing fine dust and pollutants in the air can be actively removed.

However, since the purification capacity of one such outdoor air purification system is not large, there is a limit to solve the serious air pollution problem only when hundreds of thousands of air purification systems are operated simultaneously.
