Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust filter system for a paint booth,

The present invention relates to an exhaust filtration system and method for a paint booth, and more particularly, to an exhaust filtration system and method for a paint booth which can replace an activated carbon filter To a system and method for exhaust filtration for a paint booth.

Generally, in automobile factories, auto parts makers, maintenance factories, and other factories producing industrial products, the product is painted on the product surface by finishing work.

In order to carry out such painting work up, usually painting booth is provided so that painting is performed in an airtight space, thereby improving the quality of paint and various kinds of harmful gas (including volatile organic compounds) contained in paint dust or paint And a facility which can be discharged to the outside through a certain purification device without leaving immediately outside.

In addition, such a painting booth is configured to perform a drying operation of painting the product and then drying the surface of the painted product by applying a hot hot air for drying the product, wherein the hot air generated during the drying operation escapes to the outside The paint solvent remaining in the air in the paint booth is evaporated as well as the volatile organic compounds (V.0.Cs) contained in the paint are discharged together with the paint solvent remaining in the air inside the paint booth, A purification facility for preventing the volatile organic compounds from being discharged is provided.

That is, when the volatile organic compound is released to the atmosphere, the volatile organic compound reacts with light to generate a photochemical oxide such as ozone, aldehyde, or a nitrogen compound in smog, thereby causing photochemical smog in the city, It causes pollution, causes unpleasant odor, and is treated as a carcinogen that causes disorders such as the nervous system when it comes into contact with human skin or enters the respiratory tract, and its emission standards are strict.

Therefore, when there are many paint parts such as automobiles, the painting booth is equipped with an intake and exhaust system. Especially, various substances that adversely affect the human body and the environment can be discharged to the exhaust part as described above, The device is installed.

Therefore, in the case of automobile paint booth, paint dusts among air polluting substances can be easily removed through various filters. On the other hand, in the case of volatile organic compounds generated by evaporation of solvent corresponding to 70% of paint ingredients, The treatment is very tricky.

In other words, there are various methods of treating volatile organic compounds, such as adsorption, biological treatment, direct combustion, and catalytic combustion, which are the most widely used methods at present. However, except for the simple adsorption method, It is difficult to apply it to a general enterprise or a small and medium-sized enterprise.

Therefore, a simple adsorption method, which is practically applied in the treatment of volatile organic compounds, mainly uses activated carbon as its filter medium.

Activated carbon has a large surface area due to a large number of pores. When a volatile organic compound having a relatively large molecular weight such as benzene, toluene or xylene passes through the activated carbon layer, most of the volatile organic compounds are removed by the Van der Waals force, And the volatile organic compound is adsorbed in a condensed state in the capillary.

However, due to the continuous adsorption of volatile organic compounds, the adsorption capacity of activated carbon decreases in proportion to time, and when it is saturated, new activated carbon should be replaced. In order to reduce the economic burden due to frequent replacement, Which is used for a certain period of time. However, this also deteriorates the working efficiency and also lowers the adsorption performance of volatile organic compounds.

In addition, since the replacement cost of activated carbon is high, it is desirable to desorb and recycle the volatile organic compounds adsorbed on the activated carbon, rather than replacing the activated carbon with new activated carbon. Thus, a method of recycling activated carbon has been proposed.

In order to recycle the used activated carbon, it is necessary to desorb the pores of the activated carbon and the volatile organic compounds stuck to the surface. As a method for desorbing the activated carbon, steam of at least 100 ° C or hot air is applied to the surface of the activated carbon, The volatile organic compounds are evaporated to remove the activated carbon from the surface, thereby restoring the micropores of the activated carbon to the initial state.

However, in order to install the device for desorbing volatile organic compounds such as activated carbon, there is still a disadvantage that many costs such as the installation of steam equipment, cooling water supply means and peripheral facilities are burdensome, and hot air is used as an alternative.

As described above, the activated carbon filter installed at the exhaust part of the paint booth for adsorbing various dusts or volatile organic compounds generated in the paint booth is difficult to manage after installation, and it is costly to replace with a new product after a certain period of use However, it is difficult to regenerate the activated carbon filter to such an extent as to satisfy the exhaust gas standard suited to the environmental standard even if the regenerator is actually used. Even if the regenerated activated carbon filter is used And the economical burden thereof was not greatly reduced as compared with the replacement cost of the newly installed activated carbon filter.

Accordingly, it is an object of the present invention to provide a method for increasing the replacement cycle while maintaining the performance of the activated carbon filter installed in the exhaust part of the painting booth as long as possible, thereby providing an economic benefit to a company that practically performs painting. Was raised.

In addition, depending on the product to be painted, the temperature of the raw material for coating and the temperature of the drying chamber may be changed depending on the product to be painted. Especially, the air discharged from the drying process after being painted using the small paint is discharged at a high temperature (150 to 180 ° C.) In the case of the activated carbon filter, if it is exposed to high temperature for a long time, there are various environmental factors, and there is a possibility of fire because there is a spontaneous ignition.

Therefore, the activated carbon filter installed at the exhaust part of the painting booth using the baking paint is periodically supplied with cooling water to the activated carbon filter to prevent fire from occurring due to natural ignition, thereby preventing fire from occurring by natural ignition.

However, conventionally, the cooling water supplied to the activated carbon filter is supplied from the upper part of the activated carbon filter and flows down to the natural gravity system, so that the cooling water can not be evenly supplied to the lower side of the activated carbon, .

In addition, it is also expected that the cooling water supply system generates a high-temperature evaporation gas to reactivate the clogged pores of the activated carbon filter. However, the conventional cooling water supply system can not be sufficiently supplied to the inner and lower portions of the activated carbon filter. The effect was also minimal.
