FIG. 1 is a schematic view schematically showing the configuration of a cleaning apparatus 100 for a multiple desalination apparatus filter of the present invention, and FIG. 2 is a perspective view showing the configuration of a plural desalination apparatus filter 200.

As shown in the drawing, the cleaning apparatus 100 for the multiple desalination apparatus filter of the present invention is used for cleaning the plural desalination apparatus filter 200. The multiple desalination plant filter 200 is used in a perfusion boiler of a supercritical boiler plant. The multiple dechlorination facility filter 200 includes an upper support plate 210 and a lower support plate 220, a support frame 230 for supporting the upper support plate 210 and the lower support plate 220 to maintain a spaced distance therebetween, And a plurality of filtering columns 240 disposed concentrically between the lower support plate 220 and the lower support plate 220 to filter the systematic water.

Each filtering column 240 is formed by stacking a plurality of filtering disks 245 on a vertically formed support shaft 241. The filtering disk 245 is a thin plate-like material, and a flow hole 246 through which the systematic water flows in the middle region is formed. At the lower portion of the support shaft 241, there is provided an elastic member 247 for elastically supporting a plurality of filtering discs 245.

A coil-shaped elastic member 247 is wound on the outer side of the support shaft 241 and the support plate 243 is mounted on the upper side of the elastic member 247. A plurality of filtering discs 245 are stacked on the upper surface of the support plate 243. The plurality of filtering discs 245 are moved up and down by the elastic force of the elastic member 247.

As shown by the arrows in FIG. 2, the filtering column 240 flows from the outside through the space between the filtering disks 245 and flows along the inner flow holes 246 from the lower part to the upper part, Foreign matter adheres to the surface of the filtering disk 245 and is filtered.

The multiple desalination apparatus filter 200 is separated from a flow-through boiler (not shown) for cleaning, and then assembled into the multiple desalination apparatus filter cleaning apparatus 100 to perform a washing process.

The cleaning apparatus 100 for a multiple desalination apparatus filter according to the present invention cleans the inside of the filtering disk 245 by passing the cleaning liquid through the cleaning liquid in a direction opposite to the flow direction of the systematic water and injects the cleaning liquid to the side of the filtering column 240, And the outside of the disk 245 is cleaned.

To this end, the cleaning apparatus 100 for a multiple desalination apparatus filter of the present invention includes a cleaning liquid receiving tank 110 for receiving a cleaning liquid, an internal cleaning unit 130 for cleaning the inside of the filtering disk 245 by passing the cleaning liquid in a reverse direction, An external cleaning part 140 for cleaning the outside of the filtering disk 245 by spraying the cleaning liquid onto the side surface of the filtering column 240 and an external cleaning part 140 for cleaning the cleaning liquid in the cleaning liquid receiving chamber 110, And a cleaning liquid supply pump 120 for supplying the cleaning liquid to the valve 140.

The cleaning apparatus 100 for a multiple desalination apparatus filter includes a support frame 150 for supporting a plurality of desalination apparatus filters 200 and a support frame 150 for supporting the support frame 150 in a state of being spaced apart from the cleaning liquid receiving vessel 110 by a predetermined height (Not shown).

The cleaning liquid receiving chamber 110 is provided below the plural desalination facility filters 200. The cleaning liquid container 110 receives the cleaning liquid and allows the cleaning liquid to be supplied to the internal cleaning part 130 and the external cleaning part 140 by the cleaning liquid supply pump 120. Further, the cleaning liquid container 110 receives the cleaning liquid contaminated by internal cleaning and external cleaning.

Here, since the foreign substance attached to the surface of the filtering disk 245 is an oxide, the cleaning liquid is provided as a pickling fluid for cleaning the oxide. For this purpose, it is preferable that a diluted hydrochloric acid solution is used as the washing liquid.

The cleaning liquid receiving chamber 110 is divided into a first storage space A in which clean clean liquid is not contaminated and a second storage space B in which a cleaning liquid contaminated by cleaning is received. The first storage space A and the second storage space B are separated by two partition walls 111 and 113 to prevent dilution of clean and contaminated cleaning liquid. The upper partition wall 111 is formed from the upper part to the lower part and the lower partition wall 113 is formed from the lower part to the upper part.

The first storage space A is provided with a cleaning liquid supply pipe 117 for discharging the cleaning liquid to the outside of the cleaning liquid container 110. At the end of the cleaning liquid supply pipe 117 disposed inside the first storage space A, a filter 119 is provided. The filter 119 filters the washing liquid once to filter impurities in the washing liquid. The cleaning liquid supply pipe 117 is connected to the inner cleaning liquid supply pipe 131 and the outer cleaning liquid supply pipe 141.

A cleaning liquid discharge pipe 115 is provided at one side of the second storage space B for discharging contaminated cleaning liquid to the outside. A clean cleaning liquid is replenished in the first storage space A as much as the contaminated cleaning liquid discharged through the second storage space B.

The cleaning liquid supply pump 120 is driven according to whether or not the power is supplied, and supplies the cleaning liquid to the internal cleaning part 130 and the external cleaning part 140. Clean rinsing liquid in the first storage space A flows through the rinsing liquid supply pipe 117 and is supplied to the inner rinsing liquid supply pipe 131 or the outer rinsing liquid supply pipe 141 as the rinsing liquid supply pump 120 is driven.

The cleaning liquid supply pump 120 according to a preferred embodiment of the present invention is provided with a diaphragm pump in which the pressure of the cleaning liquid supplied to the outer cleaning part 140 and the inner cleaning part 130 varies with time. The pulse pump gradually increases and decreases the pressure of the cleaning liquid at regular intervals according to the passage of time.

The elastic member 247 supporting the filtering disk 245 is elastically lifted and lowered by the pressure difference to which the cleaning liquid is supplied. A separation distance is generated between the filtering discs 245 stacked on each other due to the vibration impact generated by the lifting and lowering of the elastic member 247 and the cleaning liquid is discharged to the outside through the separation distance to clean the inside and the outside of the filtering disc 245 do.

By using the cleaning liquid supply pump 120 for supplying the cleaning liquid at a variable pressure, the cleaning efficiency can be increased as compared with the case where the cleaning liquid is supplied at a constant pressure.

The pulsation pump is preferably selected to have an appropriate hydraulic pressure range in consideration of the elastic force of the elastic member 247 and the capacity of the multiple desalination apparatus filter 200.

The internal cleaning portion 130 primarily cleans the outside and inside of the filtering disk 245 by spraying the cleaning liquid downward from the top of the filtering column 240. The internal cleaning part 130 includes an internal cleaning liquid supply pipe 131 connected to the cleaning liquid supply pipe 117, an internal supply valve 133 disposed on the internal cleaning liquid supply pipe 131 for interrupting the supply of the internal cleaning liquid, And a cleaning water chamber 135 provided on the support plate 210 to receive washing water.

The inner cleaning liquid supply pipe 131 receives the cleaning liquid from the cleaning liquid supply pipe 117. The internal cleaning liquid supply pipe 131 supplies the cleaning liquid supplied at a variable pressure to the cleaning water chamber 135.

The internal supply valve 133 interrupts the supply of the cleaning liquid. The internal supply valve 133 is opened when the internal cleaning part 130 of the multiple desalination facility filter 200 is firstly cleaned and closed when the external cleaning part 140 is secondarily cleaned.

The washing water chamber 135 receives the washing liquid and allows the washing liquid to flow into the respective filtering columns 240 through the systematic water inlet holes 211 on the surface of the upper supporting plate 210. The rinsing liquid moves along the bottom at the top of the filtering column 240. That is, the cleaning liquid moves from the upper part to the lower part along the flow holes 246 of each filtering disk 245 forming the filtering column 240 as shown in FIG. 3, and the pulsation pressure of the cleaning liquid supply pump 120 The filter disc 245 is separated from the filter disc 245 by an impact caused by the impact.

Since the movement path of the cleaning liquid is opposite to the moving direction of the system water, the foreign matter adhering to the surface of the filtering disk 245 can be efficiently removed by separating from the system water.

After the primary cleaning is completed by the internal cleaning part 130, the external cleaning part 140 secondly cleans the outside of the filtering column 240. [ The external washing section 140 is disposed on the side surface at a predetermined distance along the outer periphery of the multiple desalination apparatus filter 200. The external cleaning section 140 includes an external cleaning liquid supply pipe 141 branched from the cleaning liquid supply pipe 117, an external supply valve 143 provided on the external cleaning liquid supply pipe 141 for interrupting the supply of the cleaning liquid, And an external cleaning liquid supply nozzle 145 for spraying onto the side of the column 240.

The external cleaning liquid supply pipe 141 is disposed on the side of the multiple desalination facility filter 200 so as to inject the cleaning liquid to the side of the plurality of concentrically arranged filtering columns 240. A plurality of external cleaning liquid supply pipes 141 are disposed at intervals of a predetermined angle so that the cleaning liquid is uniformly sprayed to the plurality of filtering columns 240.

Further, an external cleaning liquid supply pipe 141 is provided at both the upper and lower sides along the axial direction so that the upper and lower portions of each filtering column 240 are uniformly cleaned.

The external supply valve 143 and the external cleaning liquid supply nozzle 145 have the same functions and functions as those of the internal supply valve 133 and the internal cleaning liquid supply nozzle 135, and thus the detailed description thereof will be omitted.

The operation of the cleaning apparatus 100 for a multiple desalination apparatus filter according to the present invention having such a configuration will be described with reference to FIGS. 1 to 4. FIG.

The operator removes the multiple desalination facility filter 200 from the boiler (not shown) and then fixes it on the filter support frame 150. When the multiple desalination apparatus filter 200 is fixed, the cleaning liquid supply pump 120 is driven.

At this time, the inner supply valve 133 is opened and the outer supply valve 143 is closed. The cleaning liquid supplied from the first storage space A to the cleaning liquid supply pipe 117 by the cleaning liquid supply pump 120 is supplied to the cleaning water chamber 135 through the inner cleaning liquid supply pipe 131. [

The cleaning liquid is supplied by repeatedly increasing and decreasing the hydraulic pressure by a variable pressure of the cleaning liquid supply pump 120 at regular intervals. The cleaning liquid supplied to the cleansing water chamber 135 is supplied from the upper part of the filtering column 240 to the lower part through the system water inflow hole 211 of the upper support plate 210 as shown in FIG. The inside of the filtering disk 245 stacked by the moving direction of the cleaning liquid is primarily cleaned.

Further, the elastic members 247 are lifted up and down in accordance with the change in the supply pressure of the cleaning liquid, and the vibration damping generated thereby causes the adjacent filtering discs 245 and 245a to be in contact with each other (D) as shown in FIG.

The cleaning liquid flows out of the filtering disks 245 and 245a through the separation distance d generated between the neighboring filtering disks 245 and also the outside of the filtering disk 245 is cleaned. Since the inflow direction of the cleaning liquid is opposite to the moving direction of the system water, the pickling still attached to the surface of the filtering disk 245 can be cleanly cleaned.

The cleaning liquid that has been cleaned by the filtering disk 245 falls into the second storage space B of the cleaning liquid receiving chamber 110 and is stored.

On the other hand, when the primary cleaning of the internal cleaning part 130 is completed, the operator closes the internal supply valve 133 and opens the external supply valve 143. The cleaning liquid is moved to the external cleaning liquid supply pipe 141 through the cleaning liquid supply pipe 117 and is injected to the side of the filtering column 240 through the external cleaning liquid supply nozzle 145.

The cleaning liquid bumps against the side surface of the filtering column 240 and secondarily cleans the outside of the filtering disk 245.

When the secondary cleaning by the external cleaning part 140 is completed, the external supply valve 143 is closed and the power of the cleaning liquid supply pump 120 is shut off to complete the cleaning of the plural desalination facility filters 200.

As described above, according to the present invention, the cleaning apparatus for the multiple desalination apparatus filters is operated while maintaining the assembled state without disassembling the filtering columns.

The outside of the filtering disk and the inside of the filtering disk are primarily cleaned, and the outside of the filtering disk is cleaned secondarily from the side, thereby improving the cleaning efficiency.

Particularly, the cleaning liquid is supplied to vary the supply pressure so that the cleaning liquid flows into the interior of the filtering disk, thereby further enhancing the cleaning efficiency.

Therefore, since the process of disassembling and assembling is unnecessary, the time and manpower required for the filter cleaning can be reduced.

Meanwhile, according to a preferred embodiment of the present invention, a purifying apparatus is provided with a plurality of desalination apparatus filters fixed on a filter supporting frame, but the filter supporting frame may be rotated in some cases. In this case, since the plural desalination facility filters are rotated, the cleaning efficiency can be further improved.

The embodiments of the cleaning apparatus for a multiple desalination apparatus filter of the present invention described above are merely illustrative and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. You will know the point. Therefore, it is to be understood that the present invention is not limited to the form described in the foregoing description.
