Description

Water rotary jet waste gas scrubber {APPARATUS CLEANING WASTE GAS OF WATER REVOLUTION JET TYPE}

The present invention relates to a water rotary jet waste gas scrubber, in particular, to maximize the physical agitation effect and simplify the maintenance, to reuse the washing water infinitely, to prevent the discharge of steam with dioxin and to collect the waste gas close to the complete The present invention relates to a water rotary jet waste gas scrubber that enables automatic adjustment.

Among the various types of dust collectors widely used in the related art, the dust collector of the water jet type air cleaner according to the present invention is known from Utility Model Publication No. 20-0200371, and an incinerator for burning waste is provided, It is provided, the air purifier is connected to the incinerator and pipes, the inside of the vane is formed on the outer circumferential surface and both ends of the water supply rotating shaft is formed with a pulley, the one side and the other side of the rotary shaft of the part where the vane is formed The nozzle for injecting is protruded, and the gas inlet and the gas outlet are formed in the outer peripheral one end part and the other end part.

In addition, a pump for supplying water to the rotating shaft of the air purifier is configured inside the reservoir.

The dust collector of the water jet type air purifier is advanced without resistance due to the inertia in which the sucked gas is dispersed from the center of the van by the van to the outside. Therefore, a vacuum film is formed in the center part of the van provided in plurality, and the stirring effect of water particle and waste gas is inadequate. Thus, in order to improve the stirring effect, when the dust collectors are installed in parallel, they are inclined by about 10 to 15 degrees, but they are alternately installed, but dust and waste gas collection are not smooth.

Then, the trouble of having to replace the used washing water to some extent and the second waste water treatment problem occurs.

In addition, since the vane and the nozzle must be installed in a single cylinder, the entire repair must be dismantled during the internal repair, and thus, the maintenance work is difficult, and there is a problem in that steam from the hot washing water in the water tank is scattered to the outside.

In addition, since dust collection was mainly focused on the waste gas, it was negligible to treat harmful gases, and thus, there were many shortcomings when the waste dust gas treatment close to 100% had to be processed.

The present invention was devised to solve the above-mentioned conventional defects and problems, maximizing physical agitation effect, simplifying the maintenance, and reusing the washing water infinitely, preventing the discharge of steam with dioxins and making waste gas close to perfection. It is an object of the present invention to provide a water rotary jet waste gas scrubber that is capable of collecting as well as automatically adjusting in operation.
