Description

PURIFY APPARATUS OF NOXIOUSNESS USING RAINDROP}

The present invention relates to an apparatus for purifying harmful gases using fresh water, and more particularly, to deodorize or remove odors and dioxins contained in harmful gases generated during incineration of wastes using fresh water, and to exhaust them into the air. Hazardous gases have sufficient reaction with water or purification solution (hereinafter referred to as 'purification water'), so it is not only effective purifying but also has no vibration, noise and low power cost unlike ordinary wet hazardous gas purifier. The present invention relates to a device for purifying harmful gases using a drop of water so as to minimize it.

In general, the last decade of the twentieth century was a time when environmental problems were recognized and expanded to the global scale, and at the same time, it became clear that civilization of consumption was deeply related to environmental problems.

And one of the environmental problems that have a great relationship with this civilization is the 'mass waste problem'.

Since industrial wastes are discharged by type, animal manure and construction waste account for about 80% of the total, and the remaining years of the final disposal site show that the remaining capacity in the metropolitan area is low.

The rubbish problem is a matter of quantity and quality.

The 'quantity problem' began to surface due to the massive increase in the amount of waste that could not be adequately handled and disposed of, resulting in a surge in illegal dumping of surplus wastes illegally.

'Quality problem' is due to the fact that the occurrence of the impact on the natural environment and the health of the local community due to the drop of harmful substances, in addition to the dioxins generated by the generation or combustion of water pollution by the harmful substances contained in the garbage. It began to surface.

In the past, local governments have responded to the problem of garbage in terms of hygiene and based on incineration, which leads to widespread waste reduction.

However, since the incineration process does not prevent the increase in the amount of waste, it is obvious that sooner or later there will be a shortage of the final disposal site, and there is a problem that the possibility of recycling the waste is cut off.

From this point of view, the shift from one-way type incineration to landfill to recycling type with emphasis on reduction and recycling is important.

Here, dioxin is emitted in a large amount from the exhaust gas of the incinerator, and sulfur dioxide gas (hereinafter referred to as "sulphite gas") is released into the air by oxidation of sulfur contained in crude oil during the refinement of petroleum or when heavy oil is burned.

In particular, as the energy source is converted to petroleum, the concentration of the emission of harmful components as described above gradually increases, and the air pollution is seriously worsening day by day.

In addition, in order to prevent such air pollution, the discharge limit of hazardous components is very strict, so a purifier suitable for such a standard is required, and in a clean room for manufacturing a semiconductor or a clean room of a pharmaceutical company, high cleanliness is required. A large supply of air with is required.

In order to meet these demands, various types of devices for purifying such harmful gases have been proposed.

For your reference, you can classify the device for purifying harmful gas into wet and dry.

Here, the representative example of the wet type is a packed tower purifier, and when looking at its structure, a gas ejection pipe is installed below the large tank, and a plurality of wire meshes are installed above the wire meshes. This is done by installing a water spray pipe on it so that water is evenly soaked on the surface of the granular body.

This causes the polluted gas to be ejected from the gas ejection pipe installed under the large tank so that the polluted gas rises and reacts with the water applied on the surface of the granules as it exits between the stacked granules stacked in multiple layers. Only this dissolved and purified gas is raised and discharged.

Therefore, it is only in contact with water while the polluting gas escapes between the granules, the contact area with water is limited, the purification efficiency is low, there is a problem that the facility is huge.

Another type of wet purifier is a stirring purifier, which looks at its structure by installing a gas ejection pipe under a tank filled with water and a propeller that is rotated by a motor above it. As the bubbles generated are destroyed by the propellers, only the purified gas is raised and discharged by contacting with water to react.

However, this is because the buoyancy of the bubble is stronger than the rotational force of the water by the propeller, the rate of rise of the bubble is faster and accordingly there is not enough time for contact with the water, the harmful gas is not enough to react with the water, there is a problem that the purification efficiency is low. In addition, since a large propeller of the same diameter as the tank must be used, the motor must also use a large one, which causes severe vibration and noise, high power costs, and bubbles in the center and both ends of the propeller do not receive any rotational force. As it rises, there is a problem that the purification efficiency is further lowered.

In addition, there is a method for purifying the polluting gas dry, but there is a Cottrell dust collector, which has a critical problem of low efficiency and excessive equipment cost compared to wet.

As described above, most pollutant gas purifiers are not operated due to excessive facilities cost and insufficient performance, causing civil complaints due to pollution. Therefore, it is necessary to prepare fundamental measures. have.

In addition, if one of the known techniques to solve the above-mentioned problem is described as an example (Korean Patent Publication No. 91-447), it is sprayed the purification solution inside the columnar tank to form a vortex and in the same direction as the vortex By spraying the polluting gas, the bubbles of the polluting gas become long and thin and then disappear, thereby dissolving the polluting gas in the purification solution.

To this end, the contaminated gas can enter the purification solution which is vortexed at high speed without resistance, and at this time, the rotational force of the purification solution is stronger than the buoyancy of the bubble caused by the polluting gas. It is a purification method and a device in which gaseous contaminants react with a solution and are dissolved by disappearing.

Therefore, after the contaminated gas becomes a bubble, the length of the ascending rotation is very long, and the contact time with the purifying solution is much longer than that of the above-described wet purifiers. Therefore, harmful components of the contaminating gas are effectively absorbed by the purifying solution, and Compared with the wet purifier, improved purification efficiency can be obtained, and the size of the equipment can be made compact and the cost of the equipment can be greatly reduced.

However, in recent years, more stringent standards have been applied to fine dust and harmful gases such as dioxins, and as the environment deteriorates, the generation of refractory pollutants such as dioxins is increasing. A high-efficiency purification device is needed, and environmental facilities require frequent complaints, making it difficult to secure installation sites and increasing facility costs in proportion to the occupied area. It is becoming.

In addition, the above-mentioned purification means have been economically burdened with enormous financial resources in maintaining and operating the facility.

The present invention is to solve the above-mentioned problems, the purpose is to deodorize or remove the odor and dioxin contained in the harmful gas generated in the process of incineration of waste, etc. by using fresh water and then exhausted into the air Hazardous gases that use harmful water can be used to minimize the economic burden because of the efficient purification and the absence of vibration, noise and low power costs, unlike ordinary wet hazardous gas purifiers. It is to provide a purification device.
