Abstract

PURPOSE:To perform the purification of exhaust gas in a short section, by providing a dish-shaped disc and a piercing hole to the hollow shaft in a cylindrical canister and mounting a fan for exhausting air. CONSTITUTION:A hollow shaft 2 is supported in a corrosion resistant cylindrical canister 1 comprising stainless steel in a rotatable manner by a bearing unit 3 and dish-shaped discs 4 comprising durable material quality such as PVC are fixed to the shaft 2 at an arbitral interval 5. A liquid having chemicals fitted to the properties of exhaust gas dissolved therein is stored in a liquid tank 7 and the chemical liquid in the liquid tank 7 is introduced into the shaft 2 under pressure through a liquid feed pipe 8 and a pump 9 and the shaft 2 is rotated by a motor 18 to suck in exhaust gas from a suction port 10. The chemical liquid injected from a piercing hole 6 violently impinges against the discs 4 to be formed into a spray state and mixed with the exhaust gas to absorb the contaminant in the gas. Purified air is exhausted to an exhaust port 15 by a fan 14 and the contaminated liquid is discharged from a discharge port 16.

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to an apparatus for sucking polluted gases to be discharged and performing processing such as cleaning, deodorization, evaporation, and cooling.

"Prior Art" Conventionally, there has been an exhaust gas treatment device in which exhaust gas is passed through a disc while injecting water to neutralize, oxidize, decompose, and purify pollutants in the exhaust gas.

"Problems to be Solved by the Invention" As mentioned above, the conventional exhaust gas treatment equipment did not have a suction device, and no special consideration was given to the material of the disc or the cleaning liquid to be sprayed, so the performance was insufficient. The present invention attempts to solve this problem.

"Means for solving the problem" The present invention is equipped with a fan for sucking out air to achieve high performance, and uses a liquid in which chemicals adapted to the characteristics of exhaust gas are dissolved. However, since the material of the disk was selected according to the characteristics of the exhaust gas, the purification effect could be carried out effectively in a short period of time.

"Examples and effects" DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings, which illustrate an example of the implementation of the present invention.

1 is the can body, which is formed into a large diameter cylindrical shape and is installed in a stationary state.
Depending on the characteristics of the exhaust gas, any material such as iron, stainless steel, PVC, FRP, etc. can be used in consideration of corrosion and cost. 2 is a hollow shaft, with both ends attached to bearing unit 3.
It is rotatably supported. Reference numeral 4 denotes a disk, which is dish-shaped and is fixedly attached to the hollow shaft 2 at an arbitrary interval 5, and is made of durable material with little chemical change such as PVC, ABS, polycarbonate, titanium, stainless steel, etc. Use a certain material. Reference numeral 7 is a liquid tank in which liquids containing suitable chemicals are used for exhaust gas cleaning, when the gas is acidic or alkaline, for deodorization, for evaporative concentration, cooling, etc., as described later. It is used between furrows. Reference numeral 8 denotes a liquid feeding pipe, the proximal end of which comes out from the liquid tank, and the distal end inserted into the end of the hollow shaft 2. A pump 9 is interposed in the pipe 8, and the chemical solution in the liquid tank 7 is forced into the hollow shaft from the liquid tank 7. 10 is an exhaust gas suction port, 11 is a guide plate, and the exhaust gas sucked in is transferred to a disc 4.
It guides you in the direction. Reference numeral 12 denotes a large-diameter disk for droplet separation, which has a larger diameter than the disk 4 and is fixedly attached to the hollow shaft 2 at the fixed end of the disk 4, and rotates together with the shaft. The liquid that collides and becomes atomized and adsorbs contaminants in the exhaust gas is brought into contact with the separation large-diameter disc 12, the gas and liquid are separated, and the liquid is dripped. Reference numeral 13 denotes an eliminator, which is made of a disc-shaped body with a gap that houses a water droplet separating material such as a bent type.A hollow shaft 2 passes through the center of the eliminator, and the outer end is connected to the can body 1 to form a stationary state. This is to separate droplets in the gas that cannot be removed by the large-diameter separating disc 12 and still remains.

Reference numeral 14 denotes a fan whose center part is connected to the hollow shaft 2 and rotates to suck out the air inside the can. A suction port 15 that opens into the can body 1
This system exhausts purified air. Reference numeral 16 denotes a drain port through which liquid that has absorbed pollutants in the exhaust gas is discharged. 17 is a liquid injection pipe, 18 is a motor, 1
A pulley 9 rotates the hollow body 2.

Furthermore, when treating exhaust gas by weighing it in a liquid tank and pressurizing it into a hollow shaft, if the pollutants in the exhaust gas are acidic (Hcl! * SO2, Hz S, etc.), alkaline chemicals are added. When using a liquid containing a product and the exhaust gas is alkaline (NHs, RNAz, R
: l N, etc.), use a solution containing an acidic chemical. Next, to deodorize exhaust gas, in the case of organic odorous substances, use an oxidizing agent such as alkaline sodium hypochlorite solution or a detergent mainly containing organic surfactants. (ammonia, amines, etc.)
For organic acidic, alkaline, or neutral mixed gases, stabilized chlorine dioxide is activated using a chemical solution that neutralizes or decomposes, such as sulfuric acid, hydrochloric acid, or sodium hypochlorite. can be used to oxidize and decompose them.

When deodorizing the above organic gas, the effective concentration of sodium hypochlorite or chlorine dioxide is set at an appropriate concentration in the cleaning solution by controlling the concentration of residual chlorine. In addition, in the case of evaporative concentration and cooling, the air drawn into the bottom by the fan at the top becomes atomized by the circle vi4, and the contact between the liquid and the exhaust gas is performed with high efficiency, and dry air or high temperature air is sucked. The air that exits becomes saturated air or steam, and the water evaporates and becomes concentrated.However, in the case of cooling, by using a chemical solution that you want to keep as cold as possible, you can cool the high-temperature exhaust gas and bring the exhaust air to room temperature. effective.

Since the present invention has the above-described configuration, when using it, the chemical solution in the liquid tank 7 is forced into the hollow shaft by the pump 9 through the pipe 8, and the hollow shaft 2 is rotated by the motor 18. , and further suction port 1
It sucks in exhaust gas from zero. Then, the chemical-containing liquid ejects from the through hole 6, collides with the dish-shaped disk 4, becomes a spray, mixes with the pressurized exhaust gas, absorbs contaminants in the gas into the atomized liquid, and is sucked by the fan 14. Air is discharged while being purified in the direction of the outlet 15, and the thus contaminated liquid descends and is discharged from the discharge port 16. At this time, in order to improve gas-liquid separation, the cutting plate 1
It is even more efficient to use Eliminator-2 or Eliminator-13.

In carrying out the present invention, it is possible to use a vertical type or a horizontal type as required.

``Effects'' In the present invention, a suction fan is developed to suck out gas, which intensifies the atomization and movement of the chemical liquid that comes into contact with the exhaust gas, and improves the neutralization, oxidation, and decomposition efficiency of waste particles. In addition to improving efficiency, we are researching ways to shorten the equipment itself and reduce equipment space, improve durability by adapting the properties of the materials of each component, and adapt cleaning chemicals to the type of exhaust gas. By developing and using it, cleaning, deodorizing, evaporating, concentrating, cooling, etc. of exhaust gas can be performed simply and efficiently, and it is highly effective in all respects.
