Abstract
Description
The present invention relates to an assembly comprising a clean filter for a horizontal wet scrubber and to a method of construction thereof.
Currently, the semiconductor and display industries, which occupy one of the main industries in Korea, produce various kinds of gases during the manufacturing process. The gas is usually treated by a scrubbing method, an electrodeposition method, or a mixed method thereof.
The scrubber is the most common environmental equipment used for decades to purify gas. It injects liquid from above and blows up polluted gas from below to absorb and remove the gaseous material dissolved in the liquid. The solid material collides with the fine droplet It is the principle. Therefore, the longer the time the gas and the liquid meet, the greater the amount of the substance absorbed or collided with the gas, thereby improving the treatment efficiency.
Among such scrubbers, there is a horizontal type wet scrubber which is disposed horizontally rather than vertically and moves in a horizontal direction and supplies liquid to the upper end and the front end of the gas-liquid contacting portion as a spray (see FIG. 8) .
There are various types of packing materials placed in the scrubber. Examples of typical adsorbents include activated carbon described in JP-A-61-35849, adsorbents of basic substances such as NaOH, Ca (OH) 2 and Mg (OH) 2 described in JP-A No. 61-61619, There is a case where the activated carbon and the basic substance described in JP-A No. 5322674 are mixed. When the adsorbent is saturated, the ability of adsorbing toxic substances is remarkably lowered. Therefore, there is a problem that the adsorbent must be regenerated or exchanged after a certain period of use. In addition, there is a problem that it is somewhat inadequate to deal with a large amount of harmful gas treatment because the pressure drop is large.
In another method, there is a filter type for increasing the contact time and area of gas and liquid. Or a combination thereof may be used. A material such as activated carbon used as an adsorbent is used as a filtration medium, and an aqueous solution to which an additive is added is sprayed (Patent Publication No. 10-0340384).
The randomly oriented individual fibers of Laid-Open Publication No. 2013-0041928 comprise a multi-component fiber having a first region having at least a first melting temperature and a second region having a second melting temperature, The first melting temperature is characterized by being below the second melting temperature.
