Description

Rotary stirring polluted air purifier {THE APPARATUS OF PARIFYING WASTE GAS}

The present invention relates to an apparatus for purifying polluted gas, and more particularly, to purify polluted gas inevitably generated in various industrial sites, incinerators, chemical and domestic wastewater treatment plants, etc. in a more efficient form through a step-by-step three-step reaction process. The present invention relates to a rotary stirring polluted air purification device which is discharged into the atmosphere.

With the rapid development of the industry, due to the explosive increase in the population, the natural resources of water, air and forest resources are being severely damaged and polluted. Due to the damage and pollution of natural resources, Even today's survival is threatened.

Since such environmental pollution is not a problem that can be solved by a specific region or country, a joint response is urgently discussed around the world, and as a result, all regions and countries are in mutual solidarity with each other today. We are working hard to make a difference.

However, despite these efforts, harmful substances such as sulfurous acid gas (So2), which causes acid rain, and nitrogen compounds and environmental hormones, which are the main causes of various adult diseases, cancer, and other rare incurable diseases, are caused by the use of automobiles. The engine exhaust gas and the chimneys of various industrial sites are continuously being discharged to the atmosphere, and the emission is also increasing year by year, which is a serious hazard to the health of the people.

In recent years, contaminated gas deodorizers have been provided as essential components in various industrial sites, and various contaminant gases are purged and treated to be discharged within the environmental standard range through such facilities. Pollutant gas deodorizers are generally divided into oil type, pressurized water, and rotary water reactors.

For example, the flow type reactor is to fill a certain amount of liquid in the reaction chamber, and to form and clean a large amount of droplets, liquid film, bubbles by the inflow of contaminated gas, which is S type, Impera type, Rota Type, fractional type, spiral guide vane type, or the like;

In addition, the pressurized water reactor is a method for cleaning the contaminated gas by pressurized supply of the cleaning liquid, which is Venturi Scrubber, Jet Scrubber, Cyclone Scrubber, Packed Tower And the like;

Finally, the rotary water reactor is a water droplet, water film, bubbles by using the rotation of the blower to clean the polluted gas, which is composed of the Daisen Washer (Iisen Washer), Impulse Scrubber (Impulse Scrubber), etc. Can be.

However, in the pollutant gas purification device as described above, first, the conventional flow type reactor is to install a nozzle in a solution, and to allow the pollutant gas to be injected at a constant pressure from the nozzle to mix the solution and the polluted gas, This caused a problem that bubbles are generated by the gas injected, and the bubbles are floated on the surface of the solution to leak without being reacted with the solution. Also, the nozzle hole is clogged due to sludge generation due to continuous use. It is to have a problem that the efficiency is extremely reduced.

In another contaminant gas deodorizing device described above, the hydrostatic and rotary water reactors disperse the solution in all directions from the nozzle installed at the upper side, and again supply the contaminated gas from the inlet installed at the lower side, The polluting gas is purged by the falling solution. Therefore, such a device cannot fully cover the entire polluting gas due to the falling characteristics of the dispersed solution. It was to have a problem of a considerable decrease in the reaction efficiency to act as.

On the other hand, recently solved the problem of the above-mentioned conventional pollutant deodorizing device, a rapid rotary collision pollutant purification device has been invented by the inventor of the present application (patent registration No. 0789719).

However, the rapid rotary collision type pollutant gas purification device as a pre-registration technology is intended to partially increase the purification efficiency by vortex generation and bubble dispersion by the supply of the purification solution and the pollutant gas, but the rate of increase is very high. It was lacking, giving problems that did not reach as expected.

For example, in order to purify the polluted gas efficiently, the pre-registered quick rotary collision polluting gas purification device is not limited to how long the purifying solution and the pollutant gas are contacted and reacted. As a simple space configuration, in addition to the mixing disc for scattering prevention, there was no configuration that can sustain the reaction time at all, thus maximizing the purification efficiency by delaying the reaction time as much as possible. The development of a pollutant purifier that made it possible to do so was an urgent challenge.

Accordingly, the present invention is to solve the limited functional problems of the conventional pollutant gas purification device, including a rapid rotary collision type pollutant gas purification device is a pre-registered technology;

An object of the present invention is to contaminate the contaminated gas to be purified with the purifying solution through the inlet duct, and then to simultaneously supply the combined substance (reactant) into the reaction chamber by a high pressure operation. , The reaction materials supplied are subjected to three stages of purification, for example, primary purification by stirring blades, secondary purification by porous plates installed in a multi-stage structure, and tertiary purification by an underwater reaction vessel. By providing smooth rotation through the flow process, the reaction time and mixing rate of the polluting gas and the purification solution are greatly increased, thereby providing a rotary stirring pollutant air purifying device for more stable and efficient pollutant gas purification treatment. Is in.

On the other hand, another object of the present invention, the stirring blade is rotated by the inlet pressure of the reaction material, for example, mixed pollutant gas and the purification solution flowing at a high pressure, to perform the first purification reaction, thereby causing unnecessary external It is to provide a rotary stirring contaminated air purifying device to eliminate the additional configuration of the energy source, thereby reducing the power consumption, to dramatically improve the economics.

Thus, as a specific means of the rotary stirring contaminated air purification apparatus according to the present invention for achieving the above object;

An apparatus for purifying polluted gas, comprising a purge solution storage chamber, a reaction chamber, and a purge air discharge chamber;

A stirring blade having a free-rotating structure is installed at the center of the overflow pipe center installed upright in the reaction chamber, and a pair of upper and lower porous plates having a multi-stage spaced arrangement structure is installed on the upper surface of the stirring blade. On the lower end of the overflow tube leading to the solution storage chamber, further installation of the underwater reaction vessel is achieved.

Therefore, the rotary stirring contaminated air purifying apparatus according to the present invention, the reaction material flowing in the form joined with the purification solution through the inlet duct, for example, the contaminated gas, by a freely rotating stirring blade to perform a blow action 1 The secondary purification treatment, and the primary purified polluted gas, the secondary purification treatment by the flow guide action of the porous plate installed in a multi-stage structure, and again, after the secondary purification treatment, monthly flow into the purification solution storage chamber The resultant reactant is subjected to a third purification process by an underwater reaction vessel, and the reaction frequency and time of the polluting gas and the purification solution, and the mixing rate thereof are extremely increased, thereby making the pollutant gas purification work more stable and efficient. To do;

Alternatively, the stirring blade is freely rotated by the pressure of the reactant flowing at high pressure, thereby smoothly purifying the polluting gas without unnecessary external power source, thereby preventing energy waste, and thus, economical efficiency. This is to be extremely improved, which provides a very useful expected effect.
