GAS ROTATION MOVING TYPE COMPLEX CHEMICAL WASHING DEODORIZER FOR ELIMINATING OF PARTICULATE MATTER AND ODOR} for removing fine dust and odor

The present invention relates to a deodorizer for cleaning chemical liquids, and more specifically, during the rotational movement of particulate contaminants such as oil mist and (fine) dust soaked in the first chemical liquid at the Venturi inlet portion, the first chemical liquid is again rotated in the outer cyclone portion. In addition, it improves the efficiency of removing fine particles by inducing the merging and dropping of particulate contaminants by supplying them, and supplies the second chemical to the discharged inner cylinder after being purified from the cyclone outer cylinder to remain in the contaminated air from which the particulate contaminants have been removed. Equipped with a gas removal inner cylinder to remove gaseous pollutants, such as odor-causing substances, to significantly reduce the odor of exhaust gas, but by installing a guide plate in the shape of a multi-layered structure in the gas removal inner cylinder to remove particulate contaminants Revolving fluid type complex chemical cleaning deodorizer for removing fine dust and odor that prevents contamination of the first chemical solution by discharging the second chemical solution to the outer portion of the cyclone while the contaminated air is introduced.

Recently, as interest in the environment has increased, complaints and damages caused by dust or odor-causing substances contained in industrial sites are increasing. Especially, odors caused by emissions from odor-producing industries And the air pollution problem continues to rise, and the impact on the health environment of nearby residents is increasing.

In general, most of the odors in the typical dyeing industry among odor-producing industries are generated in tenter facilities and coating facilities, which are post-processing processes. In particular, in high-temperature tenter facilities, oil mist, which is a high concentration/high viscosity odor substance, (fine) dust It is being discharged in large quantities.

The tenter process, which is performed by a tenter facility owned by over 70% of dyeing companies, is a process of drying and heat-treating dyed fabrics to improve the quality of fibers.It is used not only to use various chemicals, but also to increase wear resistance at high temperatures. I am using These various chemicals and oils are volatilized by the high-temperature environment (180~230℃) experienced in the tenter process, and are discharged as particulate (white) oil mist, (fine) dust and gaseous odor.

In this way, the exhaust gas generated in the dyeing field contains high concentration/high viscosity oil mist, (fine) dust, and various gaseous odor substances due to chemical treatment. The removal of (fine) dust and the removal of various gaseous odors from chemicals should be done simultaneously.

Accordingly, conventionally, it was common to use a cleaning scrubber composed of an absorption tower and an adsorption tower to treat exhaust gas generated from odor-producing industries including dyeing fields. In the case of such cleaning scrubbers, the removal efficiency of particulate contaminants can be achieved. However, the removal efficiency of gaseous pollutants has not reached a satisfactory level, and recently, electrostatic precipitators and the like have been considered.

In particular, the exhaust gas generated in the dyeing process is a high-temperature gas of 200°C or higher. In the case of high-temperature oil mist, it is difficult to sufficiently lower the temperature during cleaning in the cleaning scrubber, so removal efficiency by chemicals such as water sprayed in the scrubber This problem was not high, and rather, it caused a lot of water vapor, and the white smoke discharged caused the complaints and originality of nearby residents.

Accordingly, the use of an electrostatic precipitator that has high removal efficiency for both particulate and gaseous pollutants and does not generate white smoke is increasing, but the pollutants to be removed are generated from high-volume, high-volume oil mists and various chemicals. Since it is a gaseous pollutant, in the case of an electrostatic precipitator using a high-pressure current, there is a problem in that the risk of fire due to concentrated oil mist increases.

Moreover, as the electrostatic precipitator ages, there are problems in that it becomes difficult to manage and the risk of fire increases. As a result, it is possible to control particulate contaminants such as oil mist and (fine) dust and gaseous contaminants from various chemicals without the risk of fire. There is an increasing need for a new type of chemical cleaning deodorizer that removes all of them to improve the efficiency of removing odors.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

1 is an internal configuration diagram of a swirling flow type complex chemical cleaning deodorizer for removing fine dust and odor according to the present invention.

Referring to FIG. 1, a swirling flow type complex chemical cleaning deodorizer for removing fine dust and odor according to the present invention is a venturi inlet 100 that wets particulate contaminants in contaminated air by spraying a first chemical solution into the contaminated air. ), the venturi inlet is connected to one side of the upper wall and supplied with contaminated air in a state in which the first chemical is sprayed, so that it rotates in the interior space and injects the first chemical into the already wet particulate contaminants again, resulting in centrifugal force. Cyclone outer cylinder part 200 for removing particulate pollutants while inducing the merging and dropping of particulate pollutants, and installed inside the cyclone outer cylinder part, the contaminated air from which particulate pollutants have been removed flows in from below and upwards It forms a space to be discharged, and the inner upper part has a gas removal inner cylinder part 300 equipped with a nozzle for spraying a second chemical solution to remove gaseous pollutants contained in polluted air, and a narrower width toward the upper part. The horn-shaped guide plate is spaced in multiple layers on the inner lower portion of the gas removal inner cylinder, so that the second chemical is blocked from being discharged to the cyclone outer cylinder while the polluted air from which the particulate contaminants have been removed flows in from below. It comprises 400.

In general, the contaminated air flowing into the venturi inlet 100 may be composed of only particulate contaminants such as dust, but it is common to experience a high temperature environment using a large number of chemicals in most processes. In addition to particulate contaminants such as or oil mist, gaseous contaminants such as various malodorous substances are often included. In FIG. 2, the particulate contaminants contained in the contaminated air are indicated by small black particles, and the gaseous contaminants contained in the contaminated air are indicated by a brown arrow or a brown dotted line.

Accordingly, in the present invention, a gaseous odor substance having high removal efficiency is required by using a particulate contaminant such as fine dust or oil mist that can be removed by the first chemical and another type of second chemical such as sodium hypochlorite (NaClO). By purifying the pollutant gas containing all of the phosphorus gaseous pollutants, it is possible to increase the efficiency of removing odors caused by gaseous pollutants as well as fine dust or oil mist.

The venturi inlet 100 is a passage through which contaminated air generated during various processes in the odor-inducing industry is supplied to a complex chemical cleaning deodorizer for purification, and as shown in FIG. 1, the diameter of the central portion is higher than both sides. It is formed in a narrowly formed Venturi tube structure.

The venturi inlet 100 is provided with a first chemical nozzle 510 connected to the first chemical tank 500, so that the contaminated air flowing from one side enters the cyclone outer cylinder 200 before the chemical liquid It is configured to be supplied in a wet state while contacting.

In the case of a Venturi scrubber that relies on the Venturi effect, the separation limit particle size of the dust that can be removed is 0.1 µm, so even if the particulate contaminants contained in the contaminated air have a small size of 0.1 µm, they can be removed with high efficiency. There will be.

The venturi inlet 100 is installed on one side of the upper wall of the cyclone outer cylinder 200, and contaminated air supplied through the venturi inlet 100 through the gas removal inner cylinder 300 It is preferable to remain sufficiently in the space within the cyclone outer cylinder portion 200 before being discharged so that it can be influenced by centrifugal force by turning and moving. That is, the passage through which the contaminated air introduced into the cyclone outer cylinder 200 can be discharged is only an inlet passage of the gas removal inner cylinder 300 located below the inner space of the cyclone outer cylinder, and the inlet of the gas removal inner cylinder Since it descends while turning in the outer part of the cyclone until it reaches the particulate contaminants wet in the first liquid, it can be affected by centrifugal force for a long time.

The cyclone outer cylinder part 200 induces the merging and dropping of particulate contaminants while rotating the polluted air supplied from the venturi inlet connected to the upper one side outer wall through the gas removal inner cylinder, thereby inducing the contaminant air to fall. It is configured to remove particulate contaminants from.

At this time, it is preferable that the cyclone outer cylinder part 200 is further provided with a first chemical liquid nozzle 520 for re-injecting the same type of chemical solution as the first chemical solution sprayed from the venturi inlet. That is, since the particulate contaminants are wetted by the first chemical in the venturi inlet part 100, it can be removed and dropped by the centrifugal force and gravity received during the orbiting motion inside the cyclone outer cylinder part 200, but the cy In the external part of the clone 200, it is possible to promote the merging of the particulate contaminants already wet in the first chemical by additionally spraying the same first chemical as the medicine in which the particulate contaminants have been wetted, so the removal efficiency of particulate contaminants having a fine size Will be able to improve.

Accordingly, FIG. 2 shows a state in which particulate contaminants are individually wetted in the first chemical solution in the venturi inlet 100 and a state in which particulate contaminants are merged in the cyclone outer cylinder 200.

As described above, the first chemical liquid injected from the venturi inlet and the cyclone outer cylinder may be different depending on the type of particulate contaminants contained in the contaminated air, but the particulate contaminants are the same as the dust having high adsorption power to water. One chemical solution may be composed of conventional water, and the first chemical solution is preferably configured to be sprayed in the form of mist through a nozzle to increase the adsorption power to particulate contaminants having a small size.

The gas removal inner cylinder part 300 is an inner cylinder that is a passage through which the polluted air from which the particulate contaminants are removed from the cyclone outer cylinder is discharged to the outside, and can remove gaseous pollutants that cannot be removed by the first chemical solution. 2 is made of a second chemical nozzle 610 for spraying the chemical.

To this end, the gas removal inner cylinder part 300 is installed in the inner center of the cyclone outer cylinder part 200 as shown in FIG. 1, and the lower part is opened so that the contaminated air from which particulate contaminants have been removed can be introduced. , The upper part is composed of a tubular tube that is open so that the purified air, which has been completely removed from the oil mist and odor by removing even gaseous contaminants, is discharged.

At this time, it is preferable that a filter part (not shown) capable of removing moisture or some remaining contaminants is further provided in the discharge passage through which the air having been removed from the gas removal inner cylinder to the gaseous pollutant causing odor is discharged. Do.

In addition, the upper region of the gas removal inner cylinder 300 is provided with a second chemical liquid nozzle 610 for spraying a second chemical solution having excellent removal efficiency of gaseous pollutants into the inner space of the gas removal inner cylinder, thereby providing particulate pollutants. The second chemical solution capable of removing the gaseous contaminants remaining in the removed contaminated air is configured to be injected into the inner space of the gas removal.

At this time, the second chemical solution may be composed of a chemical solution capable of removing the main gaseous contaminant, since the gaseous contaminant contained in the contaminated air may vary depending on the process in progress. It is preferably composed of washing water containing radicals so as to increase.

In this way, the gaseous contaminants contained in the contaminated air are removed from the inside of the gas removal inner portion by the second chemical injected from the gas removal inner cylinder portion, so that cleaner air can be discharged. That is, particulate contaminants such as oil mist and gaseous contaminants such as odor-causing substances can be removed by the first chemical agent and the second chemical solution, thereby allowing cleaner air to be discharged.

The chemical blocking unit 400 is installed in a multi-layer on the inner lower portion of the gas removal inner cylinder part 300, so that the second chemical liquid injected from the second chemical nozzle 610 leaves the gas removal inner cylinder part and the cyclone outer cylinder part Discharged to the first chemical recovery tank 700 is configured to block the flow.

To this end, as shown in FIG. 1, a plurality of guide plates made of a horn shape that becomes narrower toward the upper portion as shown in FIG. 1 are spaced apart in multiple layers at the inner bottom of the gas removal inner cylinder part 300. Is done.

At this time, since the chemical blocking unit 400 is installed inside the lower portion of the gas removal inner cylinder, the upper space of the chemical blocking unit 400 provides sufficient reaction space in which contaminated air comes into contact with the second chemical to remove gaseous contaminants. It is preferably configured.

The chemical blocking unit 400 may enter the gas removal inner cylinder after the particulate contaminants are removed, but the second chemical injected from the second chemical nozzle is transferred to the cyclone outer cylinder. In order not to be discharged, the guide plate installed on the uppermost layer of the multi-layer structure is composed of a closed guide plate 410 whose upper portion is closed, and at least one or more other guide plates installed spaced apart below the open guide plate ( 420), it is preferable that the lower portion of the guide plate installed above is installed in a partially overlapped state so as to be positioned lower than the upper surface of the guide plate installed below.

Accordingly, the polluted air that has risen through the open upper surface of the open guide plate 420 installed at the bottom moves through the spaced apart spaces between the guide plates and can enter the guide plate installed on the upper layer, thereby contaminating the air. While flowing into the removal inner cylinder part 300, the second chemical sprayed from the second chemical nozzle 610 flows down the outer side of the closed guide plate 410 installed on the top layer and is located on the lower layer. The outer side surfaces of the other open guide plates 420 are sequentially flowed down and collected in the second chemical recovery tank 800.

In this way, while installing the multi-layered guide plate, the uppermost guide plate is formed of a closed guide plate 410 with an upper portion blocked, and the second chemical solution is removed by sequentially installing the open guide plates 420 on the lower layer. 1 It is possible to remove gaseous pollutants, which are various odor-causing substances, by using a new chemical liquid in the gas removal inner cylinder while preventing it from entering the chemical recovery tank.

Accordingly, it is possible to remove odors by removing particulate contaminants and gaseous contaminants respectively while using a single tower structure without installing two or more types of scrubbers in parallel or in series. After recovering the 1st chemical solution and the 2nd chemical solution, they can be purified and reused.

That is, conventionally, when two or more types of chemicals are used to remove different types of contaminants, it is difficult to recover the chemicals used to remove the contaminants, respectively, and multiple independent scrubbers are connected in a multi-structure in which several towers are sequentially connected. Or, it was necessary to immediately discard the chemical liquid used to clean the contaminated air to remove the contaminants, but by removing the particulate contaminants and gaseous contaminants together by using different types of chemicals in one tower by the chemical blocking unit, Since the first chemical solution and the second chemical solution can be recovered and used, respectively, the installation area can be significantly reduced as compared to the case of installing a multi-structured scrubber, and thus it can be widely applied to many industrial fields.

Next, with reference to FIGS. 2 and 3, it will be described that the particulate contaminants and gaseous contaminants contained in the contaminated air are sequentially removed from the cyclone outer cylinder portion and the gas removal inner cylinder portion overlappingly formed in one tower. do.

Figure 2 is a block diagram showing that the particulate contaminants are removed by the first chemical solution in the venturi inlet and the cyclone outer cylinder according to the present invention, Figure 3 is a gaseous contaminant in the gas removal inner cylinder according to the present invention the second It is a block diagram showing removal by a chemical liquid.

At this time, the particulate contaminants contained in the contaminated air are represented by black grains, and the gaseous contaminants are represented by brown arrows or brown dotted lines, and then introduced through the Venturi inlet part 100, followed by the cyclone outer cylinder part 200 ) Within the rotation movement. The particulate contaminants include oil mist or fine dust having various sizes, and the gaseous contaminants include various gaseous odors generated in the course of chemical treatment.

Referring first to FIG. 2, the contaminated air containing both particulate and gaseous contaminants flows through the Venturi inlet 100 and comes into contact with the first chemical and is supplied to the cyclone outer cylinder 200 at one side in a wet state. do. In FIG. 2, in order to express a wet state in which particulate contaminants such as oil mist or fine dust are in contact with the first chemical solution, black particles are replaced with green particles of the index of the first chemical solution.

As described above, the particulate contaminants supplied from the Venturi inlet 100 to the cyclone outer cylinder 200 in a state wetted with the first chemical solution are rotated within the cyclone outer cylinder portion 200 while descending while rotating inside the cyclone outer cylinder portion ( 200) When the first chemical liquid injected from the inside meets again, they merge with each other to form a lump of particulate contaminants. The aggregates of particulate contaminants merged with each other are removed as they fall down after hitting the wall by the effect of gravity due to weight gain and centrifugal force received during the turning exercise.

Contaminated air from which the particulate contaminants such as oil mist or fine dust is removed while orbiting in the cyclone outer cylinder portion 200 flows into the inner cylinder through an inlet formed at the lower portion of the gas removal inner cylinder portion 300.

As described above, the contaminated air introduced from the lower portion of the gas removal inner cylinder 300 forms a multi-layered structure, and the space of the gas removal inner cylinder 300 passes through the space between the open guide plate 420 and the closed guide plate 410 spaced apart. It is fed into the interior space. In FIG. 3, this is represented by a brown arrow.

Contaminated air containing gaseous contaminants supplied to the interior space through a plurality of guide plates provided in the gas removal inner cylinder 300 is a second chemical solution (red in FIG. 3) Neutralized by colored arrows).

At this time, the second chemical liquid sprayed from the upper portion of the gas removal inner cylinder portion 300 performs a reaction in contact with the contaminated air in the internal space and then flows down the outer surface of the plurality of guide plates to the second chemical recovery tank 800 Since it is collected, it is possible to stably block the second chemical liquid from leaking into the cyclone outer cylinder and going to the first chemical recovery tank 700.

In this way, by removing various malodorous substances made of gaseous pollutants from the gas removal inner cylinder, the air discharged to the outside is cleaned by removing all particulate pollutants such as oil mist and fine dust and gaseous pollutants such as malodorous substances. It becomes the state of purified air (represented by the blue arrow in FIG. 3).

In addition, although the contaminated air at a high temperature of about 200° C., which has undergone a dyeing process, is introduced into the venturi inlet part 100, the temperature is first lowered while contacting the first chemical solution at the venturi inlet part 100, and the cyclone outer cylinder part ( 200) can also lower the temperature secondaryly by the newly injected first chemical liquid, and the gas removal inner cylinder part 300 can also lower the temperature by the newly injected second chemical liquid, thereby allowing particulate contaminants While the gaseous contaminants are removed, the temperature is lowered to near room temperature, so that it is possible to minimize the occurrence of white smoke that may be generated when hot air is discharged.

In the above-described embodiment, the removal of oil mist or fine dust, which is a particulate contaminant generated in the dyeing process, and gaseous contaminants, which are various odor-producing materials, was described, but is not limited to the removal of contaminated air generated during the dyeing process. It goes without saying that it can be applied to the purification of various polluted air containing both pollutants and gaseous pollutants.

In the above, the technical idea of the present invention has been described with reference to the accompanying drawings, but this is illustrative of preferred embodiments of the present invention and does not limit the present invention. In addition, it is obvious that anyone with ordinary knowledge in the technical field to which the present invention pertains is capable of various modifications and imitation without departing from the scope of the technical spirit of the present invention.
