Description

[0001] APPARATUS FOR ELIMINATING WHITE PLUME [0002]

The present invention relates to a device for removing white smoke, and more particularly, to a device for removing white smoke, which has a rigid assembling structure by improving the arrangement structure between components, thereby preventing vibration noise and improving durability.

Generally, the White Plume Phenomenon is a phenomenon in which when the gas containing moisture is discharged and mixed with and diffused into the atmosphere, the temperature is lowered, the water vapor in the gas becomes below the dew point, It is a phenomenon that looks like white smoke. Such white smoke may cause a lot of complaints as well as visible pollution, as condensed water containing contaminants drops around the outlet. Since the exhaust gas contains a large amount of water in the waste incineration facility or the power generation facility using a wet scrubber or a water quencher with a wet flue gas desulfurization facility or an exhaust gas treatment facility, In the case of general boilers, the humidity is low and its severity is low, but the white smoke phenomenon occurs.

There is no legal restriction on the white smoke phenomenon, but the reason for eliminating the white smoke phenomenon is to prevent the inside of the chimney from being corroded by the reaction of moisture and oxides in the exhaust gas and to improve the ventilation power of the exhaust gas by raising the exhaust gas temperature, It prevents the atmospheric diffusion from occurring, secures the watch at the time of takeoff and landing of the aircraft near the airfield, prevents deterioration of aesthetics in the city and sightseeing spot, and in the case of white smoke discharged from the wet scrubber, The water vapor in the state can not be diffused and falls down the chimney so as to prevent the water vapor from coming into contact with the surrounding vehicles, buildings,

In the case of the conventional white smoke removing apparatus, there is a heating system in which the exhaust air is heated to be discharged into a dry state at a high temperature, a condensing system in which steam is condensed by cooling the exhaust air, and a mixing system in which such a heating system and a condensing system are mixed Conventional white smoke removal apparatuses of the heating type and the condensation type have a problem in that the effect of removing the white smoke is insufficient and the conventional white smoke removal apparatus of the mixed type is complicatedly configured and the maintenance cost and the initial installation cost are excessively required There was a problem.

To solve this problem, a white smoke removing apparatus capable of reducing environmental pollution by removing moisture including pollutants in exhaust gas by using arc discharge is disclosed in Korean Patent No. 0548503. In the case of the white smoke removing apparatus disclosed in the above-mentioned Japanese Patent No. 0548503, the steam can be charged by trapping the steam contained in the exhaust gas by capturing the steam, thereby reducing the size of the apparatus and enabling installation in the exhaust pipe There is an advantage that it can be installed in a state in which the change of existing facilities is minimized.

However, in the case of the apparatus for removing white smoke using arc discharge, due to the miniaturization of the apparatus and the like, the binding of the internal components is weak and vibration noise may be generated due to the flow of the air current, and the electrode rod and the discharge plate may be damaged by an external impact.

This allows the discharge unit 130 to be supported by the lower insulator 158 connected to the lower subframe 146 as well as to the main frame 142, ) Can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus 100 for removing white smoke according to an embodiment of the present invention will be described in detail.

Referring to FIGS. 1 and 2 again, the housing 110 has an inlet (not shown) formed at a lower portion thereof and an outlet (not shown) at an upper portion thereof to allow the white smoke to flow downward and be discharged to the upper portion. The housing 110 may be formed in a hollow cylindrical shape or a polygonal tubular shape such as a rectangular shape. A dust collecting unit 120, a discharging unit 130, and the like are disposed inside the housing 110. The upper insulator 152, the lower insulator 156, the cleansing nozzle 162 of the cleansing water sprayer 160, the ultrasonic sprayer 170, and the like may be positioned on the side surface of the housing 110 .

Also, the housing 110 may be integrally formed, and may be composed of three major parts to facilitate repair and exchange. For example, as shown in FIG. 1, the housing 110 may be configured to include three sub-modules 112, 114, and 116 so that three portions can be separated. Specifically, the lower module 116 is a place where a gas that has passed through a scrubber (not shown) or the like is introduced into the lower module 116, and the washing water spraying unit 160, the airflow spraying unit 170, the lower insulator 156, can do. In addition, the intermediate module 114 is provided with a dust collecting unit 120, a discharge unit 130, and the like, and collects water vapor, fine particles, etc. by charging them. In addition, the upper module 112 may be provided with a washing water injector 160, an upper insulator 152, and the like, where the gas from which fine particles are removed is discharged.

3 is a view illustrating a dust collecting part of the apparatus for removing white smoke according to an embodiment of the present invention.

Referring to FIG. 3, the dust collecting unit 120 may include a plurality of lattice spaces 124 formed in the housing 110 and formed in the vertical direction of the housing 110. Particularly, the dust collecting part 120 may be located in the intermediate module 114 of the housing 110. As the dust collecting unit 120 is positioned in the intermediate module 114 of the housing 110, the washing water is finely sprayed by the air flow injecting unit 170 installed in the lower module 116 to be bonded to the fine particles, And the fine particles having a larger size fall down before they are introduced into the dust collecting unit 120. Accordingly, the collection efficiency of the dust collecting unit 120 can be increased.

In addition, the dust collecting part 120 may include a grating frame 122 for forming the grating space 124. The lattice frame 122 may be made of a material resistant to corrosion. The lattice frame 122 may be made of an electrically conductive material.

The lattice frame 122 may have various shapes, but the lattice frame 122 may have a rectangular cross section for space efficiency and installation convenience, so that each lattice space 124 has a hexahedral shape . This lattice space 124 allows the electrodes 132 to be arranged at regular intervals. The width of the lattice space 124 may have various lengths, and a narrower width may provide a larger number of the electrode bars 132. The spacing between the grid frame 122 and the electrodes 132 may be determined by testing according to the operating frequency and operating voltage.

4 is a view illustrating a discharge unit and an insulation unit of the apparatus for removing white smoke according to an embodiment of the present invention.

2 and 4, the discharge unit 130 includes at least one electrode rod 132 disposed in the lattice space 124 of the dust collecting unit 120, and the electrode rod 132 is connected to each lattice space 124 Respectively. Accordingly, a plurality of the electrode rods 132 are disposed with a regular spacing. The electrode rod 132 may be made of a material having high corrosion resistance, and may be made of an electrically conductive material as a whole.

In addition, the polarity of the electrode rod 132 and the dust collecting unit 120 may be changed depending on whether the electrode is a positive charge type or a negative charge type. For example, water vapor, fine particles, etc. of white smoke are charged by the corona discharge of the discharge unit 130 and the dust collecting unit 120, and are collected at the dust collecting unit 120. The collected water vapor falls by the gravity to the bottom surface side of the housing 110, and thus the white smoke can be removed.

Specifically, the water vapor contained in the gas flowing into the housing 110 is charged by the electrons emitted from the electrode rod 132, and the water vapor having electrons is moved to the dust collecting unit 120 side in the anode state by attraction, 120 on the surface of the grating frame 122. Then, the water vapor is dropletized and flows toward the bottom side of the housing 110 by gravity along the surface of the grid frame 122.

2 and 4, the supporting part 140 includes a main frame 142 disposed on the upper part of the dust collecting part 120, a supporting part 140 supported on the main frame 142 and disposed on the upper part of the dust collecting part 120 And an upper subframe 144 to which one end of the electrode rod 132 is connected and a lower subframe 146 disposed below the dust collecting unit 120 and to which the other end of the electrode 132 is connected.

Each of the electrode bars 132 can be coupled to both the upper and lower subframes 144 and 146 so that the upper and lower subframes 144 and 146 sandwich the electrode rods of the dust collecting unit 120 So as to be spaced apart from the dust collecting frame 122 and to be primarily supported. The upper and lower sub-frames 144 and 146 may include a plurality of vertical bars 144a and 146a and a plurality of vertical bars 144b and 146b disposed at predetermined intervals. Particularly, when one side of each electrode rod 132 is connected to the horizontal bar 144a of the upper sub-frame 144, the other side of each electrode rod 132 is connected to the vertical bar 146b of the lower sub-frame 146, When one side of each electrode bar 132 is connected to the vertical bar 144b of the upper sub frame 144, the other side of each electrode bar 132 is connected to the horizontal bar 146a of the lower sub frame 146, It is possible to reduce the fluctuation of the electrode rod 132 due to, for example,

The upper sub-frame 144 is supported by the main frame 142 so that the upper and lower sub-frames 144 and 146 connected to the plurality of electrode rods 132 can be supported. The main frame 142 is also connected to the upper insulator 154 located in the upper insulator 152 to support the upper insulator 154. The support portion 140 and the discharge portion 130 are electrically insulated from the dust collecting portion 120 by the upper insulator 154. [

At this time, the lower sub-frame 146 and the lower sub-frame 146 are connected to each other so that the lower sub-frame 146 and the electrode rod 132 can be more firmly supported and the support 140 and the discharge unit 130 and the dust- 120 can be further improved. That is, the lower insulator 158 is connected to the lower sub-frame 146 in addition to the insulating function, thereby performing the function of more firmly supporting the support 140 and the electrode bar 132 supported thereby. Here, when the cross section of the housing 110 is rectangular, the lower insulator 158 may be connected to at least four lower sub-frames 146 corresponding to four corners.

2 and 4, the insulation 150 includes at least one upper insulator 154 connected to the main frame 142 and at least one lower insulator 158 connected to the lower sub- ). At this time, the upper insulator 154 may be located in the upper insulator 152, and the lower insulator 158 may be located in the lower insulator 156. The upper and lower insulators 152 and 156 may be installed in the upper and lower modules 112 and 116 of the housing 110, respectively. The upper and lower insulators 154 and 158 are located outside the dust collecting part 120 located in the intermediate module 114 which is the passage through which the white smoke passes, thereby making it possible to smoothly flow the gas, 120 and the discharging unit 130 are relatively increased, and the removal efficiency of the white smoke can be increased.

Each lower insulator 158 may be connected to the horizontal bar 146a and / or the vertical bar 146b of the lower subframe 146 via a connecting bar 159. [ The main frame 142 may also extend to the upper insulator 152 in the longitudinal direction so that the upper insulator 154 is located in the upper insulator 152, 142 can be engaged with the upper insulator 154. For example, both ends of the main frame 142 may have a fork-shaped extension extending vertically in a bar-shaped portion formed laterally. The upper and lower insulators 154 and 158 may be made of a fire-retardant insulator.

1 and 2, the washing water injector 160 can inject washing water into the interior of the housing 110. As shown in FIG. The washing water jetting unit 160 serves to clean the inside of the housing 110 by spraying the washing water at predetermined time intervals. For example, the washing water spraying unit 160 can spray the washing water once every two hours.

The washing water injector 160 is provided with a washing water supply nozzle 162 passing through the housing 110 and a washing water supplying nozzle 162 through the washing water supplying nozzle 162 for spraying the washing water into the inside of the housing 110. [ And a washing water distributing pipe 164 for splitting and spraying washing water to uniformly spray the water inside the housing 110.

The washing water spraying unit 160 may be installed at the upper portion and the lower portion of the housing 110, respectively. At least one rinse water supply nozzle 162 and a rinse water distributor 164 may be installed in the upper module 112 of the housing 110 and at least one rinse water supply nozzle 162 may be provided in the lower module 116 of the housing 110 One rinse water supply nozzle 162 and a rinse water distributor 164 may be provided. At this time, the washing water branch pipe 164 installed in the upper module 112 can inject the washing water to the bottom face of the housing 110, and the washing water branch pipe 164 installed in the lower module 116 is connected to the housing 110 The washing water can be sprayed to the upper surface side of the washing water tank. That is, by injecting washing water at the upper and lower portions of the housing 110, the cleaning effect inside the housing 110 can be enhanced.

5 to 7 are views showing an airflow injector of the apparatus for removing white smoke according to an embodiment of the present invention.

Referring to FIGS. 5 to 7, the air diffusing unit 170 may spray the washing water finely into the interior of the housing 110. Fine particles contained in the white smoke are caused to coalesce and grow so that the fine particles are firstly removed before being introduced into the dust collecting part 120 and the dust particles flowing into the dust collecting part 120 As the size of the fine particles increases, the dust can be collected more easily by the discharge in the dust collecting unit 120, and the dust collecting performance of the dust collecting unit 120 can be improved because the amount of the fine particles flowing into the dust collecting unit 120 is primarily removed have.

The air injector 170 is supplied with air and includes an air supply pipe 172 for injecting air through an air hole 1721 at the distal end thereof and an air supply pipe 172 for supplying washing water through the air hole 1721. [ A cleaning water supply pipe 174 sprayed by the supplied air and an air injection nozzle 176 for finely spraying the sprayed cleaning water from the cleaning water supply pipe 174 into the interior of the housing.

For example, compressed air flows through the air supply pipe 172, and the washing water flows into the washing water supply pipe 174. The compressed air in the air supply pipe 172 is sprayed with the washing water of the washing water supply pipe 174 while passing through the air hole 1721 and the spray water sprayed in the primary direction is again injected into the nozzle holes 1761 And sprayed more finely. That is, the washing water is sprayed primarily by colliding with the compressed air, and then sprayed through the air injection nozzle 176. Through these two-step spraying, the washing water can be finely sprayed, and the size of the washing water particles can be made smaller than the size of the fine particles. By making the washing water particles smaller than the fine particles, the coagulation and growth of the fine particles to be enhanced can be facilitated.

In addition, the air injection nozzle portion of the front end where the air hole 1721 of the air supply pipe 172 is located can be detachably attached. Accordingly, the diameter of the air holes 1721 can be varied, and the size of the washing water particles can be appropriately adjusted as needed.
