Description

Swivel Flow Type Chemical Cleaning Deodorizer}

The present invention relates to a rotating fluid type complex chemical cleaning and deodorizing device capable of deodorizing odors including various kinds of contaminants generated in a dyeing process or livestock farming at a high concentration in a single process.

Recently, as interest in the environment has increased, there are increasing cases of complaints of discomfort and damage caused by dust or odor-causing substances contained in exhaust gases generated from industrial sites or livestock farms. As the problem of odor and air pollution caused by the continuous emergence of problems, the impact on the health environment of neighboring residents is increasing.

In general, among the odor-causing industries, most of the odors generated by the typical dyeing industry and livestock farms are oil mist and dust, which are highly concentrated/high viscosity odor substances generated in tenter facilities and coating facilities, which are post-processing processes, and odors generated by livestock farms. A large amount of manure dust, which is dust containing odor, is discharged in most of the country.

The tenter process, which is performed by a tenter facility owned by more than 70% of dyeing companies, is a process that improves the quality of fibers by drying and heat treatment of dyed fabrics.It uses various chemicals as well as oil to increase abrasion 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 fine particulate (white smoke) oil mist, dust and gaseous odorous substances.

The main points of occurrence of livestock odors are manure treatment facilities and livestock houses. In the manure treatment facilities, the concentration of odor gas is high, but the amount of gas is low. .

The main mechanism of occurrence of livestock odor is that odor substances, including gaseous odor substances generated inside the livestock house, move in combination with the dust inside the livestock house, and the dust generated by the livestock house accounts for a significant part of the induction of the smell.

In this way, the exhaust gas generated from the odor-causing industry includes gaseous odor substances, high concentration/high viscosity oil mist, and various gaseous odor substances according to the treatment of dust and chemicals. Removal and removal of various gaseous malodorous substances generated from chemicals must be performed at the same time.

Accordingly, conventionally, a cleaning chemical liquid cleaning device consisting of an absorption tower and an adsorption tower has been generally used to treat exhaust gas generated in the odor-causing industry. However, in the case of such a cleaning liquid cleaning device, the removal efficiency of particulate contaminants can be achieved. However, since the removal efficiency of gaseous pollutants has not reached a satisfactory level, an electric dust collector has been recently considered.

In particular, since the exhaust gas generated in the dyeing process is a high temperature gas of 200℃ or higher, it is difficult to sufficiently lower the temperature during cleaning in the cleaning liquid cleaning device in the case of high temperature oil mist. There was a problem that the removal efficiency was not high, and on the contrary, a large amount of water vapor was generated and the white smoke discharged caused complaints and anger from nearby residents.

Accordingly, there are increasing cases of using electric dust collectors that have high removal efficiency for both particulate and gaseous pollutants and do not generate white smoke, but the pollutants to be removed are generated from high-temperature oil mist and various chemicals with high volatility. Since it is a gaseous pollutant, there is a problem in that the risk of fire due to the concentrated oil mist increases in the case of an electric dust collector that uses a high-pressure current.

Moreover, as the electric dust collector ages, the difficulty of management and the risk of fire gradually increase.Therefore, all particulate contaminants such as oil mist and dust and gaseous contaminants generated from various chemicals are removed without the risk of fire. Accordingly, the need for a new type of chemical liquid cleaning device capable of improving the odor removal efficiency is gradually increasing.

For reference, the following prior art documents have listed 5 recent prior art documents searched for "drug liquid cleaning" as a keyword through the Patent Information Net Keyprise, and the technical fields related to the present invention with reference to the following prior art documents You will be able to grasp the background technology and its development status.

Publication/Registration Gazette: 1020063280000, 1020170000000, 1019971860000, 1019637650000, 1019971850000.

The present invention was developed to solve the conventional problems mentioned in the background art, and in particular, particulate contaminants generated from oil mist, dust, manure, etc. generated in dyeing processes and livestock farms, and gaseous substances generated from various chemicals or manure. It is an object of the present invention to solve the problem with a problem to remove all contaminants in a single process.

As a means to solve the above problem, the contaminated air to be supplied is first washed with the pre-treated chemical by delaying the swirling flow in the form of a cyclone into the cylinder while spraying the pre-treatment chemical solution, and then forming a double-layered space on the top of the container. Thus, it is proposed a means of introducing the first cleaned contaminated air into a multilayered space and second cleaning with a foreign post-treatment chemical solution and a filter to remove particulate contaminants and gaseous odors from contaminated air.

According to the means of the present invention, a first chemical solution suitable for removing fine particulate contaminants and a second chemical solution suitable for removing gaseous contaminants are sprayed in a single washing tower from mutually divided multilayer areas to be included in the contaminated air. After primary cleaning of particulate contaminants such as oil mist and dust, gaseous contaminants such as odor-causing substances are secondarily washed and filtered, thereby discharging into highly purified air.

Hereinafter, the present invention will be described with reference to FIG. 1.

As shown, the present invention comprises a venturi unit 100 to wet particulate contaminants in the contaminated air by spraying a first chemical solution into the contaminated air to be supplied; The venturi part 100 is connected to the upper wall of one side to receive the contaminated air in which the first chemical is sprayed, and to rotate in the internal space, and the first chemical is again injected to the already wet particulate contaminants by centrifugal force. A cyclone unit 200 for removing particulate pollutants while inducing the merging and falling of particulate pollutants; A chemical solution deodorizing unit 300 which is installed in a double layer so as to be separated above the cyclone unit 200 to remove contaminated air from which particulate contaminants have been removed with a second chemical solution and a filter to remove gaseous contaminants that cause odors; The contaminated air from which particulate contaminants have been removed from the inside of the cyclone part 200 is installed to communicate with the lower center of the inside of the cyclone part 200 to the lower part of the chemical liquid deodorizing part 300, and then the chemical liquid deodorizes. A communication part 400 formed to be discharged from the lower part of the part 300 to the upper part; A conical eaves plate 510 having a narrower width toward the top is installed in multiple layers from the top of the communication part 400 to the bottom of the communication part 400 to block the inflow of the second chemical solution into the communication part 400. Blocking unit 500; may be composed of.

The contaminated air flowing into the venturi unit 100 may be composed of only particulate contaminants such as dust, but in the case of a high temperature environment using a plurality of chemicals, such as a dyeing process, dust or oil mist and Not only the same particulate pollutant but also gaseous pollutants such as various odorous substances are often included together.

Accordingly, in the present invention, gaseous pollution, which is a gaseous odorous substance that increases removal efficiency, is required to use particulate contaminants such as dust or oil mist that can be removed by the first chemical and other types of second chemicals such as hypochlorous acid and caustic soda. By purifying polluted gas containing all substances, there is an effect of increasing the efficiency of removing not only dust or oil mist but also odors caused by gaseous pollutants.

Accordingly, the venturi unit 100 is a passage through which contaminated air generated during various processes performed in the odor-causing industry is supplied to the interior of the complex chemical cleaning and deodorizing device for purification. As shown, the diameter of the central portion is narrower than both sides. It can be made in the structure of the venturi tube is formed.

In addition, the venturi unit 100 is provided with a first nozzle 220 connected from the first chemical liquid storage unit 210 in the inner and lower portions of the cyclone unit 200 so that contaminated air introduced from one side is the cyclone unit. Before entering 200, it may be configured so that contaminated air can be supplied in a wet state while contacting the chemical solution.

In this way, the Venturi unit 100 using the Venturi effect can remove particulate contaminants contained in contaminated air with a separation limit particle diameter of 0.1 µm with high efficiency even if they have a small size of 0.1 µm. There is an effect that can be.

The venturi part 100 is connected to the upper wall of one side of the cyclone part 200, and although not shown, it is connected so as to be connected in a straight line to the quadrant of the circle on the plane, so that contamination supplied through the venturi part 100 Until the air is discharged through the chemical liquid deodorizing unit 300, it remains sufficiently in the space within the cyclone unit 200 and rotates, and slowly falls under the influence of the centrifugal force while coagulating and removing it.

That is, since the passage through which the contaminated air introduced into the cyclone unit 200 can be discharged is only the inlet passage of the chemical solution deodorizing unit 300 located under the inner space of the cyclone unit 200, the chemical solution deodorizing unit ( 300), as it slowly descends while rotating in the cyclone part 200 until it reaches the inlet of 300), particulate contaminants wetted in the first chemical solution can be mixed and rotated and aggregated and removed under the influence of centrifugal force for a long time. have.

On the other hand, the cyclone unit 200 rotates the contaminated air supplied from the venturi unit 100 connected to the upper outer wall through the chemical liquid deodorization unit 300 to prevent the merging and falling of particulate contaminants. Induction, it can be configured to remove particulate contaminants from the contaminated air once more.

To this end, the cyclone part 200 may be further provided with a second nozzle 230 for redundantly spraying the first chemical liquid sprayed from the venturi part 100, and the second nozzle 230 It is installed so as to face the upper portion of the cyclone unit 200 so as to promote the contaminants and aggregation and to delay the falling speed of the first chemical.

In this way, particulate contaminants are wetted by the first chemical solution in the venturi part 100 and thus fall and be removed by centrifugal force and gravity received during the rotational motion inside the cyclone part 200, but the cyclone In the part 200, by additionally spraying the same first chemical solution as the chemical solution that wets the particulate contaminants, it is possible to promote merging and aggregation of the particulate contaminants already wetted in the first chemical solution, as well as delay the dropping speed of the first chemical solution. By doing so, there is an effect of further improving the removal efficiency of particulate contaminants having a fine size.

On the other hand, a first chemical liquid storage part 210 is formed under the cyclone part 200 to recover the first chemical liquid supplied from the venturi part 100 and the cyclone part 200 and sinking. , Pipes and pumps may be connected and installed so as to circulate supply to the 2 nozzles 220 and 230.

In addition, the first chemical liquid sprayed from the venturi unit 100 and the cyclone unit 200 may vary depending on the type of particulate contaminant contained in the contaminated air, but the particulate contaminant has a high adsorption power for water. In this case, the first chemical solution may be composed of conventional water, and the first chemical solution may be configured to be sprayed in the form of a mist through a nozzle in order to increase the adsorption power to particulate contaminants having a small size.

On the other hand, the chemical liquid deodorizing unit 300 can remove gaseous contaminants that cannot be removed by the first chemical liquid by flowing contaminated air from which particulate contaminants have been removed from the cyclone unit 200 into the chemical liquid deodorizing unit 300. The third nozzle 320 may be configured to spray the second chemical liquid.

To this end, the chemical liquid deodorizing unit 300 is installed in a double layer above the cyclone unit 200 as shown, and the communication unit 400 at the lower part to allow contaminated air from which particulate contaminants have been removed to flow into. It may be connected to, and the upper part may be configured with an exhaust pipe 700 that is open to discharge the purified air in which the removal of oil mist and odor is completed by removing even gaseous contaminants.

In this case, a filter 600 capable of removing moisture or some remaining contaminants may be further configured in the discharge passage through which air that has been removed from the chemical liquid deodorizing unit 300 to gaseous contaminants causing odor is discharged. .

In addition, the third nozzle 320 is configured to be sprayed from the upper region of the chemical liquid deodorizing unit 300 to the lower side, and thus can be configured to remove gaseous pollutants remaining in the polluted air from which particulate pollutants have been removed. have.

In addition, the filter 600 may be installed directly under the exhaust pipe 700 to purify air from which gaseous pollutants have been removed, and to remove moisture before exhaustion.

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

On the other hand, a second chemical liquid storage part 310 is formed under the chemical liquid deodorization part 300 to recover the second chemical liquid that is supplied from the third nozzle 320 and sinks, and circulates to the third nozzle 320. Pipes and pumps can be connected and installed to supply.

In this way, gaseous contaminants contained in the contaminated air are removed from the inside of the chemical liquid deodorizing unit 300 by the second chemical liquid sprayed from the chemical liquid deodorizing unit 300, thereby discharging cleaner air. .

That is, particulate contaminants such as oil mist and gaseous contaminants such as odor-causing substances can be removed by the first and second chemical solutions, and there is an effect of discharging cleaner air through the filter. .

On the other hand, the chemical liquid inflow blocking part 500 is installed in a multi-layered lower part of the chemical liquid deodorizing part 300 so that the second chemical liquid sprayed from the third nozzle 320 escapes from the chemical liquid deodorizing part 300 and the cyclone part It may be configured to be discharged to 200 to block flow to the first chemical storage unit 700.

To this end, the chemical liquid inflow blocking part 500 has a plurality of eaves plates 510 made of a conical shape whose width becomes narrower toward the top as shown in a multilayer spaced apart from the inner lower part of the chemical liquid deodorizing part 300 Can be.

At this time, the chemical liquid inflow blocking part 500 is installed on the upper end of the communication part 400, and the upper end of the chemical liquid inflow blocking part 500 is located in the lower part of the chemical liquid deodorizing part 300, so that it is supplied through the communication part 400. The contaminated air may be configured to provide a sufficient reaction space in which gaseous contaminants are removed from the inside of the communication unit 400 by contacting the second chemical solution.

To this end, the chemical liquid inflow blocking part 500 may allow contaminated air introduced from below after the particulate contaminants are removed to enter the liquid deodorizing part 300, but the second chemical liquid sprayed from the second nozzle is The upper end may be sealed so as not to be discharged to the cyclone part 200, and a plurality of through holes 520 may be formed along the circumferential wall of the inner communication part 400 of the eaves plate 510.

In this way, the chemical liquid inflow blocking part 500 increases the contaminated air rising along the eaves plate 510 through the through hole 520 through the spaced apart space between the eaves plate 510, and the chemical liquid deodorization part 300 Since contaminated air flows smoothly into the chemical solution deodorizing unit 300, the second chemical solution sprayed from the third nozzle 320 does not flow into the communication unit 400 and the outer surface of the eaves plate 510 There is an effect of being able to be stored and recovered in the second drug storage unit 800 in the lower portion of the chemical solution deodorizing unit 300 while flowing down.

As such, the chemical liquid inflow blocking unit 500 independently removes gaseous contaminants, which are various odor-causing substances, by using a new chemical liquid in the chemical liquid deodorizing unit 300 while preventing the second chemical liquid from flowing into the first chemical liquid storage unit. There is an effect that can be done.

Accordingly, without installing two or more kinds of chemical liquid cleaning devices in parallel or in series, it is multilayered using a single tower structure to separate particulate pollutants and gaseous pollutants in separate spaces. Each is independently removed, and the first and second chemical solutions used to remove contaminants are recovered and reused.

In other words, when two or more types of chemical solutions are used to remove different types of contaminants, it is difficult to recover each of the chemical solutions used to remove contaminants. The chemical solution used for cleaning contaminated air to remove contaminants or to be connected in a multi-structure should be immediately disposed of, but by the chemical solution inflow blocking unit 500, different types of chemical solutions are used together in one tower to prevent particulate contaminants. Since both the first chemical and the second chemical can be recovered and used while removing all gaseous contaminants, there is an effect that the installation area can be significantly reduced compared to the case of installing a multi-structured chemical liquid cleaning device.

In the case of the odor generated in the dyeing process as an exemplary embodiment of the present invention, contaminated air at a high temperature of about 200° C. that has been subjected to the dyeing process flows into the venturi part 100, but while contacting the first chemical solution in the venturi part 100 The temperature can be lowered secondarily by the first chemical liquid newly sprayed in the cyclone part 200, and the temperature thirdly by the second chemical liquid newly sprayed in the chemical liquid deodorization part 300. Since the temperature is lowered to near room temperature while particulate pollutants and gaseous pollutants are removed, there is an effect of minimizing the generation of white smoke that may occur when hot air is discharged. .

In the above embodiment, the removal of oil mist, which is a particulate contaminant, and gaseous contaminants, which are various odor-causing substances, have been described, but is not limited to the removal of contaminated air generated during the dyeing process. It can be applied to the purification of various polluted air containing all gaseous pollutants.
