Description

Scrubber system for textile processing coupled with vortex type sparaying and shower type spraying using ultrasonic vibration}

The present invention relates to a scrubber system for fiber processing that combines shower-type spraying and vortex-type spraying utilizing ultrasonic vibration, and more specifically, a shower-type method and a vortex flow in order to more efficiently remove harmful gases and odors generated during fiber processing. The present invention relates to a scrubber system that maximizes the efficiency of removing harmful gases by maximizing the contact time of gas-liquid by combining the injection method of the formula method and using ultrasonic vibration technology to fine-particle the cleaning liquid.

Among the fiber manufacturing processes, yarn manufacturing processes such as spinning and spinning, or textile manufacturing processes such as weaving and knitting, rarely use water or drugs, and there are no pollutant substances from raw materials, so the effect on air or water pollution is negligible. It's about. However, in the process of processing fibers, substances that pollute the air quality along with wastewater are discharged due to the various solvents used. In the case of wastewater, it is transferred to a wastewater treatment company for consignment treatment, or is treated in the form of landfilling in other barrier-type landfills, but air pollutants must be treated within the workplace. Therefore, in the case of a textile processing facility, there is a need for a facility that increases the efficiency of removing pollutants without increasing the scale of the scrubber system.

Regarding air pollutants, VOCs are generated from glycol ether in the desizing process and squeering process of fibers, and various pollutants and methyl alcohol, methyl ethyl ketone, styrene, acrylic acid, etc. in dyeing, printing and finishing processes. Since VOCs such as ethyl, toluene, and tetrachloroethylene are generated, these pollutants must be purified and released into the atmosphere. On the other hand, in the textile processing process, since many wet processes are applied, the wastewater treatment problem may be understood to be more important, but rather, many air pollutants are released in the drying process. A scrubber is used to remove these air pollutants.

A scrubber is a device that collects solid or liquid particles floating in a gas by using a liquid. Water is usually used as a liquid, but other liquids are also used depending on the properties of the gas or particles. By dispersing liquid into gas containing dust and various pollutants, collision with particles and liquid droplets, contact of microparticles by diffusion, adhesion and aggregation of particles due to increased humidity, prevention of re-scattering of trapped particles by liquid film, Easily collect particles by increasing the particle diameter due to condensation. There are various types such as packing tower, spray tower, cyclone, venturi, ejector method, etc., depending on the liquid dispersion method and particle collection method, and in any case, it is basically composed of a liquid dispersion unit and a particle collection unit.

In order to increase the efficiency of the scrubber, the scrubber is composed of multiple stages.In the case of fiber processing, substances as pollutants contain a lot of light particles in addition to VOCs, so a device to remove them in the initial process is required to increase the efficiency.

On the other hand, various substances of the pollutant are mixed together, among which substances exist as gases or liquids at high temperatures and solidify at relatively low temperatures according to temperature changes (commonly referred to as'oil stains'). Contaminants are supplied to the scrubber at a relatively high temperature, but the temperature is relatively lowered through the liquid spraying or spraying process of the scrubber, and when used continuously, the efficiency of the spray holes in the spray pipes is degraded during this process. In severe cases, clogging may occur. In addition, the possibility of clogging the spray holes is high because the pollutant itself is a lot of viscous substances such as viscous tar substances produced by decomposition and distillation of organic substances. In the case of the fiber processing scrubber system, when the initial pollutant removal operation is not performed, there is a part that becomes more problematic due to not only viscous substances but also small particulate substances.

The present invention is to solve the above problem.

Specifically, since there are many cases where processing in the workplace is required during the fiber processing process, the size of the scrubber system is reduced, and a scrubber system with high scrubber efficiency is required.In the present invention, the overall system size is maintained while maintaining the efficiency of reducing pollutants. We intend to provide a system that can be reduced relatively. In particular, it is intended to maximize the efficiency of removing harmful gases by combining the shower type and the vortex type spraying method, and by using ultrasonic vibration technology to make the cleaning liquid fine particles to maximize the gas-liquid contact time. Furthermore, it is intended to increase the mixing efficiency of the washing liquid and prevent the occurrence of sediment.

In the case of removing contaminants in the fiber processing process, there are many small particles as well as VOCs, and thus, it is intended to provide a scrubber system suitable for fiber processing by removing them in the initial process.

In addition, in order to increase the working efficiency of the scrubber system, it is intended to provide a scrubber system that reduces contamination of the injection hole of the injection pipe and further facilitates cleaning.

The present invention for this purpose, the absorption tower is divided into a plurality of spaces by a plurality of filler layers, a cleaning liquid spraying device installed on the upper side of the space, a microbubble generator installed below the absorption tower, and the A pipe for supplying a cleaning liquid for removing harmful gases to the liquid injection device and the microbubble generator, a cleaning liquid recovery unit for recovering the cleaning liquid, and a pollutant source including fine particles into the absorption tower. In the fiber processing scrubber system that combines shower-type spraying and vortex-type spraying, including a gas inlet, the gas inlet comprises a mesh-shaped diffraction dust collecting plate to primarily remove fine particles of the gas that flows in. It is a scrubber system. On the other hand, the microbubble generating device not only plays a role of maximizing the gas-liquid contact time by miniaturizing the cleaning liquid, but also plays a role of efficiently mixing the cleaning liquid and suppressing the generation of precipitates through this.

In addition, the mesh-shaped diffractive dust collecting plate is a heating-type dust collecting plate, and it is preferable that two to three mesh-shaped plates are installed so that the air of the pollutant can sufficiently contact, that is, the effect of diffraction can be sufficiently exhibited.

In addition, the microbubble generating apparatus of the present invention may have a configuration including a housing part accommodating a rotating body, a rotating body having a plurality of circular plate parts, and a discharge part discharging microbubbles generated by the rotating body. . This configuration has the advantage that it is possible to efficiently mix the cleaning liquid composed of two or more components, thereby preventing the occurrence of sediment, and that it can be used without pretreatment of a separate mixing process.

In addition, it is more effective that the gas inlet portion of the present invention includes a gas inlet control portion, and the gas inlet control portion is controlled in conjunction with the rotational speed of the rotating body of the microbubble generator.

In addition, it is more preferable that an ultrasonic diaphragm is installed above the discharge portion of the microbubble generator. At this time, it is preferable to change the frequency applied to the ultrasonic diaphragm to determine the frequency that is the maximum current consumption value and apply it. Further, it is preferable that the shape of the diaphragm is also in the form of a perforated plate to have a diffraction effect, thereby securing more time for contact between the atomized microbubbles and the polluted gas.

In addition, it is preferable that the circular plate portion of the rotating body of the microbubble generating device includes a liquid guide portion having a relief. The liquid guide part not only helps to form bubbles, but also helps to achieve more efficient mixing of the cleaning liquid. On the other hand, in response to the acidic odor type, if the cleaning solution is a type of mixing sodium hydroxide, sodium hypochlorite, water, etc., the embossed liquid guide unit can further increase the mixing efficiency and suppress the occurrence of precipitation.

On the other hand, the liquid injection device of the present invention is composed of a spray pipe for spraying a liquid and a spray pipe support for supporting the spray pipe, it is more preferable that the injection pipe is detachable from the spray pipe support.

In addition, it is preferable that the injection pipe support has a tubular shape with an open lower portion and is fixed to the inner wall of the absorption tower, and the injection pipe is inserted into the open tubular injection pipe support.

The scrubber system according to the present invention is a more specialized form for fiber processing, and by removing small particles of dust generated during fiber processing at an early stage, the degree of contamination of the injection pipe due to these can be lowered, and when the pollutants are removed, initial contamination is removed. There is an advantage of increasing the efficiency and reducing the size of the overall scrubber system. In particular, there is an effect of maximizing the efficiency of removing harmful gases by combining the shower type and the vortex type spraying method and using ultrasonic vibration technology to make the cleaning liquid fine particles to maximize the gas-liquid contact time.

In particular, the configuration of the microbubble device has the advantage that it can be used without a separate pretreatment of the mixing process. Furthermore, the generation of sediment can be prevented by efficiently mixing the cleaning liquid composed of two or more components, and the embossed liquid guide unit and the ultrasonic vibration technology further increase the efficiency of fine particles of the cleaning liquid to maximize the gas-liquid contact time. The efficiency of removing harmful gases can be maximized.

In the case of removing contaminants in the fiber processing process, there are many small particles as well as VOCs, and thus, it is intended to provide a scrubber system suitable for fiber processing by removing them in the initial process. In addition, not only can the overall efficiency of the system be improved, but also the safety of the working environment can be promoted through contamination of the injection pipe and the convenience of cleaning.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art may easily implement the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein.

In order to clearly describe the present invention, parts irrelevant to the description have been omitted, and the same reference numerals are assigned to the same or similar components throughout the specification.

In addition, in various embodiments, components having the same configuration will be described only in a representative embodiment by using the same reference numerals, and in other embodiments, only configurations different from the representative embodiment will be described.

Throughout the specification, when a part is said to be "connected" with another part, this includes not only the case of being "directly connected", but also being "indirectly connected" with another member therebetween. In addition, when a part "includes" a certain component, it may mean that other components are not excluded but other components are further included unless otherwise stated.

1 is a conceptual diagram of a scrubber system for fiber processing of the present invention. In general, the flow of harmful gas flows from the bottom to the top, and the used absorption liquid flows from the top to the bottom to absorb and remove the harmful substances of the gas. If there is a large amount of solids, there is also a trend flow method that makes the flow of gas-liquid from top to bottom, and the gas fluid flows horizontally and the absorbent liquid flows from top to bottom to reduce pressure loss. There is also, but most of the counterflow type as shown in the drawing is dominated. This is a process in which the cleaning liquid is supplied to the cleaning liquid spraying device 100 through the cleaning liquid pipe 310, the supplied cleaning liquid is sprayed through the injection pipe, and the cleaning liquid containing contaminants is discharged through the cleaning liquid recovery pipe 320. The present invention is a scrubber system characterized in that the gas inlet 500 into which the gas of the pollutant is introduced is provided with a diffractive dust collecting plate 510 in the form of a mesh to primarily remove fine particles of the incoming gas. In addition, in the present invention, the microbubble generator 400 is provided to maximize the gas-liquid contact time, thereby maximizing the toxic gas removal efficiency, and further, the microbubble generator is a characteristic of a pollutant generated during fiber processing. It has a feature that can be more optimized for a fiber processing scrubber by initially applying the removal of substances such as dust together with the gas inlet.

The role of the scrubber is not limited to gas absorption, and the actual scrubber is used not only for gas absorption, but also for stripping, distilling, deodorizing, vaporizing, and removing dust and droplets. However, the contaminant source in the fiber processing process is insufficient only in the configuration of the conventional wet scrubber, and thus, in the present invention, it has a constituent part capable of initially attempting to remove fine particles.

The absorption tower 300 fills a filler in the middle of the tower or installs a distributor and redistributor in order to increase contact efficiency. In some cases, there are two to three filling layers. In this case, a redistributor is installed between each stage of the filling layer so that drift does not occur inside the filling layer. In the present invention, by providing a microbubble generator, which is one of the vortex spraying method, at the lower end of the absorption tower, there is an advantage that the filler layer, which is usually composed of three stages, can be composed of two stages.

In the case of multi-stage installation, the pressure loss is somewhat large and the amount of absorbent liquid retained in the tower is large. If necessary, the efficiency of removing contaminants is doubled through the filler layer 200 installed in multiple layers. Those used as fillers may vary, and selection of the shape, size, and material of construction of the filler is important. The characteristics of the particular filler chosen can also affect the size and operating costs of the plant. In general, magnetic fillers are used in limited cases, such as when the temperature is high, and plastic fillers are most widely used due to various advantages such as economical aspects and small filling specific gravity. When using plastic fillers, special attention should be paid to corrosion resistance and heat resistance. On the other hand, in order not to cause drift, the size of the filling is designed to be smaller than 1/8 of the tower diameter and the height of the tower is designed to be 2.5 or more of the tower diameter. In addition, driving should be maintained at 40 to 80% of flooding. A sampling pipe and a drain valve are installed under the absorption tower 300 to periodically check the physical properties (pH, ORP, etc.) of the cleaning liquid, and when it is above a certain value, the drain valve is opened to drain, and a new cleaning liquid is supplied. Sight glass is installed on the outside of the absorption tower to visually check whether the contact is actually being made well. Sufficient space must be secured above and in front of the absorption facility to enable inspection and maintenance, and a work table, passage facility, and stairs are installed to inspect the inside and outside of the absorption facility.

The basic configuration of the present invention is as follows. An absorption tower 300 whose interior is divided into a plurality of spaces by a plurality of layers of fillers 200, a liquid spraying device 100 installed above the space, and a microbubble generator installed below the absorption tower (400), a pipe for supplying a cleaning liquid for removing harmful gas to the liquid injection device and the microbubble generator, a cleaning liquid recovery unit for recovering the cleaning liquid, and a pollutant source including fine particles. It is a type including a gas inlet part supplied into the absorption tower. As mentioned above, it is a more optimized form especially for the contaminants generated in the fiber processing process.

The gas inlet 500, which is one of the characteristic parts of the present invention, introduces a configuration in the form of a dry scrubber. Part of the dust collection method was introduced to remove the fine particles initially. In the case of pollutants in the fiber processing process, it is necessary to remove them first because they contain a large number of pollutants of small particles as well as VOCs. It is possible to consider removing these pollutants through an air filter, but it is impossible to apply them because the amount of pollutants is large, and if they are applied, it is difficult to operate the scrubber because it takes a very large pressure. You lose. In the case of the contamination source of fine particles generated during the fiber processing process, there are insufficient parts only by the spraying process of the wet scrubber. In the present invention, it is preferable to provide a diffractive dust collecting plate 510 in the form of a mesh at a portion of the gas inlet 500 into which noxious gas is introduced. It is intended to primarily collect small particles generated in the fiber processing process. In addition, taking the shape of a mesh network allows diffraction without interfering with the flow of gas, thereby increasing the time for the contaminants of small particles to contact the diffraction collector plate. Further, it is preferable that the diffractive dust collecting plate is provided with two or more, as mentioned in the name, to maximize the advantage of increasing the contact time by allowing more diffraction to occur. Two to three dust collecting plates are appropriate in the case of a mesh shape in a line that does not interfere with the flow of air. In short, the mesh-shaped diffraction dust collecting plate is a heating-type dust collecting plate, and it is preferable that two to three mesh-shaped plates are installed so that the air of the pollutant can sufficiently contact, that is, the effect of diffraction can be sufficiently exhibited.

The mesh-shaped diffractive dust collecting plate is a wet scrubber system and a dry scrubber system in part, and is especially optimized for fiber processing scrubbers. The dry method includes a method using pyrolysis and a plasma decomposition method, and in the case of the plasma decomposition type, there are shock, spark discharge, arc discharge, and the like. In the dry method, the plasma method is in the spotlight compared to the method using pyrolysis. In the case of the plasma method, it can be generated by applying a high voltage current voltage between the two electrodes.When a gas that can form plasma, such as an inert gas, is passed between these arcs and heated to a very high temperature, the gas is ionized. In this way, plasma is formed by generating various kinds of reactive particles, and fine particles are removed using the electrostatic force of the particles. However, this method requires a separate device for this, and, as mentioned above, it is not easy to construct at the fiber processing site. Therefore, in the present invention, a dust collection type of pyrolysis or heating type is used. In the case of fine particles in the fiber processing process, this method is rather suitable. The mesh-shaped diffraction dust collecting plate 510 basically takes the form of a mesh, and is available in the form of a hot wire, thereby removing fine particles in a high temperature state.

In the present invention, another method of removing fine particles at the beginning is to employ a vortex spraying method with a microbubble generator. The microbubble generating device 400 includes a housing part 405 for accommodating a rotating body, a rotating body 410 having a plurality of circular plates 430, and a discharge part for discharging microbubbles generated by the rotating body ( 415). This configuration has the advantage that it is possible to efficiently mix the cleaning liquid composed of two or more components, thereby preventing the occurrence of sediment, and that it can be used without pretreatment of a separate mixing process.

A gas inlet portion through which harmful gas is introduced is formed above the discharge portion 415 of the microbubble generator, so that the pollutant source initially contacts it in the absorption tower. The cleaning liquid supplied to the microbubble generator is introduced into the housing of the microbubble generator. When the microbubbles generated by the rotation of the rotating body installed in the housing are discharged to the discharge section, the harmful gas is discharged to the microbubbles and Come into contact.

The microbubble generator is possible in various types of devices. 2 shows an example. In the present invention, the device is preferably installed at the lower end of the absorption tower 300 and installed at the lower end of the gas inlet, which is an inlet of pollutants. The overall microbubble generator includes a housing part, a rotating body 410 in which a plurality of rotating plates 430 are stacked on the housing part, a receiving part in which the axis of the rotating body is mounted, and a micro-bubble formed by rotation of the rotating body. It basically has a discharge part from which bubbles are discharged.

In the case of this type, as shown in FIG. 3, in each of the rotating plates, a plurality of rotating plates 430 are stacked at regular intervals. The supplied cleaning liquid is sucked into the rotating body by the rotation of the rotating body. Each rotating plate is provided with an embossed liquid guide portion 435 so that the cleaning liquid can spread. The role of the liquid guide part 435 is to allow the liquid to spread over the entire plate without being concentrated in one place, and to spray the liquid from the rotating body to the discharge part 415 in this well-opened state. Even in the case of the discharge part 415, it is preferable to configure it to correspond to each of the rotating plates as shown in the drawing. In the case of the microbubble generating apparatus of the present invention, the discharge portion is formed as shown in the drawings, so that the generation efficiency of the microbubbles can be increased, and eventually, the area in which the pollutant source contacts can be increased through sufficient bubble generation, thereby increasing the efficiency. As shown in the drawing, a plurality of liquid guide portions 435 are provided in a radial shape from the center, but it is more preferable to increase the spraying efficiency of the liquid guide portion having a branched end.

The liquid guide part not only helps to form bubbles, but also helps to achieve more efficient mixing of the cleaning liquid. In general, the occurrence of odor appears in complex properties, and the components of odor can be considered largely acidic, alkaline, and neutral. In general, the types of sulfides and organic acids are acidic, and the types of nitrogen compounds are alkaline. On the other hand, in response to the acidic odor type, if the cleaning solution is a type of mixing sodium hydroxide, sodium hypochlorite, water, etc., the embossed liquid guide unit can further increase the mixing efficiency and suppress the occurrence of precipitation.

Although not shown in the discharge portion, a separate spray fan may be formed. When a spray fan is installed, it is generally considered a form in which a gear connection is formed in the housing part by interlocking with the motor of the spray fan, and the gear connection part is interlocked with a gear of the shaft of the rotating body to rotate. I can. The cleaning liquid supplied into the housing of the microbubble generator comes into contact with the rotating body, and the liquid is split into small particles as the rotating body rotates.

On the other hand, gas from the pollutant source is supplied, and the speed of supply may be controlled by the gas inlet control unit 520. It is preferable that the gas inflow rate of the gas inflow control unit 520 is controlled by the degree of contamination of the pollutant source or in connection with the speed of the rotating body 410 of the microbubble generator 400. When the efficiency of generating microbubbles is further increased, the amount of gas as a pollutant source can be increased, thereby enabling a more efficient system operation.

On the other hand, it is preferable to further increase the efficiency of generating microbubbles by installing an ultrasonic vibration plate at the top of the discharge portion of the microbubble generator. Although the microbubbles come into contact with the pollutant source, but there are those falling down by gravity, the microbubbles contacting the ultrasonic diaphragm become small particles again, so that they can be brought into contact with the pollutant source. Ultrasonic vibration is used to prevent scale, which degrades efficiency in heat exchangers such as boilers, prevents aquatic organisms from sticking to the surface of a ship, thereby preventing fuel efficiency from dropping, or preventing the occurrence of green algae in reservoirs or lakes. Or, it is applied in a wide variety of fields, such as increasing the extrusion efficiency by lowering the viscosity in plastic extrusion. In the case of the embodiment of the present invention, as a result, it is very effective in preventing scale of the scrubber and the filling layer.

Ultrasonic vibrators generally used include magnetostrictive vibrators using magnetostriction and piezoelectric vibrators using piezoelectric phenomena. Magnetostriction refers to a phenomenon in which a ferromagnetic material becomes elastically deformed when it is magnetized, and is also referred to as a magnetic distortion phenomenon. It is caused by an internal impact in the magnetic body due to the anisotropic energy required to magnetize the magnetic body in a certain direction along the crystal axis. Conversely, when an external mechanical impact is applied to a magnetic material, the magnetization state (magnetization rate) of the magnetic material is changed. A material with prominent magnetostriction is used as a magnetostrictive material, and a piezoelectric vibrator is made using it. On the other hand, when some kind of crystal is placed in an electric field, distortion occurs, or when distortion is applied, piezoelectricity is generated. Using this phenomenon, a piezoelectric vibrator is used as a vibrator and a resonator. Piezoelectric materials that convert electrical energy and mechanical energy using crystal polarization include single crystal crystal, lithium decarbonate, lithium niobate, and ceramic zircon titanate and barium titanate. In the present invention, the shape of a piezoelectric vibrator is preferred. A transducer is attached to the diaphragm and operates at an appropriate driving frequency.

On the other hand, if the driving type of the ultrasonic vibrator is largely divided, the circuit that oscillates and provides a fixed frequency regardless of the fluctuation of the load, and the power and power by changing the oscillation frequency supply voltage and current according to the oscillation condition of the vibrator according to the application of the load There is a frequency tracking method that controls the frequency. The method with a fixed frequency is useful for washing machines and humidifiers with relatively little or no load change, and its efficiency is not suitable for a method in which the energy of the vibrator is directly supplied by mechanically connected to the object. In the above-described embodiment of the present invention, it is preferable to use a frequency tracking method. The resonance frequency of the ultrasonic vibrator varies depending on the temperature and stress of the vibrator, and also varies depending on the surrounding environment, that is, the load condition (physical properties of the material in contact with the vibrator, temperature, flow velocity, etc.). This is because an optimal driving state is required according to these different conditions. In the case of the present invention, since the resonant frequency will fluctuate greatly depending on the type of pollutant source, driving conditions, etc., it is desirable to adjust the driving frequency according to the operating conditions.

Further, in the case of the present invention, since the diffractive dust collecting plate 510 uses a heating method, fine particles may adhere to the diffractive dust collecting plate and remain unremoved. Of course, they will be eliminated as the proper pressure is generated by the wind blown from the gas inlet control unit. However, in order to increase the removal efficiency thereof, in the present invention, it is more preferable to install an ultrasonic vibrator even in the case of a diffractive dust collecting plate.

In the present invention, on the other hand, spraying efficiency and workability can be improved by making the liquid spraying device detachable. 4 to 6 show embodiments related thereto. There is an injection pipe support 10 in which the injection pipe 50 can be stably supported or the injection pipe can be accommodated. The injection pipe support 10 is fixed to the absorption tower 300 of the scrubber. It may be welded at the time of equipment construction, or it may be fixed by various coupling means. The injection pipe support 10 has an internal space capable of accommodating the injection pipe 50, and after the injection pipe 50 is inserted, it is preferable to stably fix the injection pipe itself to some extent. A method of fixing the injection pipe 50 after being inserted into the injection pipe support 10 may be various. A structure of a screw thread and a screw bone is provided on the surface of the injection pipe, and after the injection pipe is inserted, it may be fixed to the outer wall portion of the absorption tower 300 by using a nut-like injection pipe fixing member 55.

5 is a cross-sectional view of the open tubular injection pipe support 10 and the injection pipe for the IV portion. The support can be implemented in a wide variety of ways. Most of the absorption towers of the scrubber are basically cylindrical, but of course there may be cases where they are not, and thus some deformation may be possible. First of all, as an embodiment, it is preferable that the injection pipe support 10 as shown in the drawing has a tubular shape provided with an internal space, but has an open lower portion. The injection pipe 50 is inserted into the injection pipe support 10 so that the injection pipe can be seated. The injection pipe 50 is provided with an injection nozzle 51, so that a portion of the injection nozzle 51 is located in an open portion of the injection pipe support. In FIG. 6, a cross-sectional view of part IV of FIG. 4 is shown, showing a form in which the injection nozzle 51 is located in the open portion of the injection pipe support. The spray nozzle 51 may be of various shapes. The cleaning liquid spraying device 100 should have a good dispersion of the cleaning liquid. There are some parts that directly contact contaminants by spray droplets due to the dispersion efficiency of the cleaning liquid itself, but there are many parts in which the cleaning liquid is evenly dispersed in the filler layer 200 so that the contaminants come into contact with it and absorb the contaminants with the cleaning liquid. In order to spray more evenly on the filler layer, the nozzle spray method is the most preferred method. The above configuration can clean the injection pipe of the scrubber system without frequent interruption of operation of the scrubber system, and thereby, the operation efficiency of the scrubber system and safety of the working environment can be achieved. In other words, since the scrubber injection pipe is detachable, it can be operated 24/7 without a complete interruption of the scrubber system, and the injection pipe of the scrubber can be cleaned easily, and the operator can be protected from harmful gases.
