Description

Nozzle apparatus for cleaning road {Nozzle apparatus for cleaning road}

The present invention relates to a nozzle device for a clean rod, and more particularly to a nozzle device for a clean rod.

There are various floating dusts with a diameter of 0.1㎛ to 100㎛ in the air. Among them, dust with a size (diameter) of 2.5㎛ or less is classified as fine dust "PM2.5", and the size is 2.5㎛ to 10㎛. is classified as fine dust "PM10".

When PM2.5 is inhaled for a long period of time, it penetrates deep into the alveoli without being filtered by the nasal mucosa and is known to increase early mortality along with asthma, allergic rhinitis, bronchitis, emphysema, and alveolar damage. In order to protect the environment, the cause of fine dust is institutionally regulated, while a fine dust measuring device is installed in a specific place to continuously detect the area, time and concentration of fine dust generated, and related information is provided through a situation board or daily forecast. is notified in real time.

As of the end of December 2016, there are 11 types of national air pollution monitoring networks in Korea, and there are a total of 509 locations in 96 cities and counties nationwide. Among them, there are only 423 meteorological stations nationwide that measure the concentration of fine dust, excluding the 86 meteorological stations of the metal monitoring network and the hazardous air substance monitoring network that do not have a PM2.5 measurement function for fine dust.

In general, the fine dust reduction system is a system that reuses cleaning water for road environment management. By spraying underground water or cleaning water on the road through nozzles installed on the roadside, the temperature of the road and its surroundings is lowered and dust scattered in the air is also removed. can do.

Conventional fine dust reduction systems play a large role in reducing the concentration of fine dust in the air because they prevent dust or foreign matter accumulated on the road from being blown into the air from clean underground runoff or various cleaning water sources ejected from nozzles. In addition, it is a system that plays an eco-friendly role in many ways because it cleans the road and prevents the heat rays phenomenon in which the temperature rapidly rises in the case of hot summer.

Meanwhile, fine dust, which directly threatens public health and life, such as the frequent occurrence of high concentrations of fine dust classified as a first-class carcinogen by the World Health Organization (WHO), is now emerging as a matter of national concern and a national disaster. there is. For this reason, interest in fine dust reduction systems is growing.

However, in the conventional fine dust reduction system, cleaning water is simply sprayed on the road repeatedly at regular intervals by the control unit to remove scattering dust and foreign substances. Therefore, there is a problem in that cleaning water is wasted even when there is no fine dust, and a small amount of cleaning water is provided even though the fine dust is continuously bad, so that it cannot properly respond to the environment.
