Description

Air Purifying System For Atmosphere Using Collision-typed Scrubber The present invention relates to an air purification device, and more specifically, to an air purification device using an impingement scrubber in which treatment efficiency and performance are improved by supplying a larger amount of water to the center of the main chamber. Various industrial sites generate hazardous substances as a result of industrial activities. With the growing importance of the environment, there is a trend toward strictly regulating the emission of hazardous substances. Some hazardous substances are released into the atmosphere in gaseous form, but these are typically purified through designated purification devices before being released. Volatile organic compounds mixed in the atmosphere must be treated through various processes such as combustion, catalytic oxidation, carbon adsorption, biofilters, and plasma before being released into the atmosphere. Each of these treatment methods has its own advantages and disadvantages, such as the problem of secondary pollution or cost. Regarding this problem, Korean published patent No. 10-2015-0123355 proposes a device for removing harmful gases and dust generated during metal surface treatment. The present invention is intended to propose improvements to a device for treating harmful gases and dust in a manner similar to this prior art. FIG. 1 is a cross-sectional view of an air purification device using an impact type scrubber according to an embodiment of the present invention. FIG. 2 is a planar configuration diagram of an air purification device using an impact-type scrubber according to an embodiment of the present invention. FIG. 3 is a perspective view of a grating of an air purification device using an impact-type scrubber according to an embodiment of the present invention. FIG. 4 is a side view of the second water supply section of an air purification device using an impact-type scrubber according to an embodiment of the present invention. FIG. 5 is a perspective view of the water supply section of an air purification device using an impact-type scrubber according to an embodiment of the present invention. FIG. 6 is a perspective view of a gas-liquid collision plate of an air purification device using a collision type scrubber according to an embodiment of the present invention. FIG. 7 is a plan view of a flow distribution plate of an air purification device using an impact type scrubber according to an embodiment of the present invention. FIG. 8 is a partial enlarged view of an air purification device using an impact-type scrubber according to an embodiment of the present invention. Hereinafter, the specific details of the present invention will be described in detail with simultaneous reference to the attached FIGS. 1 to 8. An air purification device using an impingement scrubber according to the present invention (hereinafter referred to as the air purification device) refers to a device that wetly treats pollutants such as fume, mist, dust, and highly soluble harmful gases and chemicals. It is generally referred to as a wet dust collector or a wet dust collector and is mainly used for capturing soluble harmful gases (NH3, HCl, H2S, etc.). The air purification device cleans dust-laden gas using droplets, liquid films, bubbles, etc., to promote attachment to particles and mutual aggregation, thereby separating particles directly from the gas flow or allowing gaseous pollutants to be absorbed and removed by the cleaning liquid. The air purification device includes a cleaning water storage tank (1), a main chamber (3), a purification unit (5), and a blower (7). The cleaning water storage tank (1) is an open-top tank in which a certain amount of cleaning water (W) is stored. The main chamber (3) is installed upright directly above the cleaning water storage tank (1). The main chamber (3) and the cleaning water storage tank (1) may be formed as a single unit. The main chamber (3) may be in the shape of a cylinder or a polygonal cylinder. An exhaust pipe (9) is connected to the top of the main chamber (3) in the form of a chimney. The exhaust pipe (9) guides the purified gas to be exhausted to the outside. The purification unit (5) is installed in a stacked manner inside the main chamber (3) and processes harmful gas (G) supplied from below in stages. The blower (7) forcibly supplies harmful gas (G) into the cleaning water storage tank (1). The blower's air outlet (7a) is open toward the liquid level of the cleaning water (W) stored in the cleaning water storage tank (1). The high-temperature harmful gas (G) forcibly supplied by the blower (7) receives an upward airflow due to the inflow pressure and its own temperature, and as a result, rises toward the upper part of the main chamber (3). Each component constituting the purification unit (5) is installed in a stacked manner inside the main chamber (3). At the bottom of the main chamber (3), a flow distribution plate
