Description

The Wet Scrubber With waste Water self-Treatment}

The present invention relates to a wastewater self-treatment wet dust collector, and more particularly, to install the wastewater treatment unit integrally with the wet dust collector so as to clean up contaminated water periodically and not generate waste water by re-entry, and also use of water. It provides an eco-friendly wet dust collector which is less than the existing one and has excellent dust collection efficiency. This also greatly improves the quality and reliability of the product so that consumers can plant a good image.

As we know, wet scrubber is a device that removes powder, liquid, and gaseous fine particles suspended in gas.It is first used to remove fine particles and gaseous substances contained in flue gas of boiler. It is now used in industrial sites to prevent soot and other particulates from factory chimneys. Such microparticles | fine-particles are fine to 1 micrometer or less of 1 micrometer.

Dust collection methods are largely mechanical and electrical, and dust collection methods that produce high efficiency at low cost are mechanical. Mechanical is divided into dry dust collector and wet dust collector. Wet dust collection is more efficient and widely used even in mechanical systems.

The dry dust collector removes air containing dust through a filter. This method is suitable for use in a place with low dust generation, but when used in a place with a large amount of fine dust or in an industrial site with a lot of gaseous substances, the processing load of the filter is easily generated, and the cumbersome and gaseous substances requiring frequent cleaning of the filter are required. Since the silver passes through the filter has a disadvantage that the efficiency is lowered. In addition, if the management of the filtration filter is neglected, the function of the filtration filter is lost, and dust is not filtered and is easily released into the atmosphere.

The filtration filter is likely to be ruptured or deteriorated by moisture, acidic gas, alkaline gas, etc. contained in the exhaust, and the load is excessively large, so that the life of the filter is reduced when the hole of the filter medium is clogged, causing cost increase. Therefore, wet dust collection method is more efficient and widely used for dust collection facilities in tunnel construction sites, sawmills, and industrial sites in which gaseous substances are generated.

The wet dust collector is a method of being separated and removed by being moistened with moisture while passing through a water layer into which dust and gaseous substances are injected. It can remove dust from contaminated air regardless of gaseous substance type and dust generation amount, and there is little extra management cost after installation.

In addition, it absorbs or neutralizes harmful exhaust gas and particulate matter to increase the contact area between the gas and the liquid, thereby increasing the dust removal efficiency and is the most widely used type. The amount of gas to be processed is applied to 3㎥ / min or more, and the efficiency varies depending on the composition of the gas, but is generally 95% or more.
