The present invention relates to a washing ball descaling device of the condenser fluid transport pipe cleaning device, and more particularly, to install a ball storage tank circulating the washing ball in the form of a cyclone, the connection portion of the inlet pipe connected to the conduit venturi pipe By forming the shape, the washing balls with scale residues are strongly struck by the baffle plate and sieve in the ball storage tank as the principle of cyclone, and the scale residues on the washing balls are shaken off neatly and flowed into the condenser with water. In order to improve the cleaning efficiency of the fluid transport pipe is to be introduced into the fluid transport pipe is faster than the washing ball.

In general, the inner surface of the fluid transport pipe installed inside the condenser is attached to the foreign matter such as debris or dirt contained in the fluid in the process of circulating the fluid not only hinder the flow of fluid, but also fluid transport pipe Due to the foreign matter stuck to the inner surface of the thickness of the fluid transport tube was unevenly thick, there was a problem that heat exchange is not made properly.

Therefore, in the past, the capacitor was dismantled or disassembled to remove it when the scale was attached to the inner surface of the fluid transport tube installed in the condenser. However, in order to solve the problem, a sponge or the like is installed in the condenser where the fluid transport tube is installed. The technique of removing the scale attached to the fluid transport pipe by the flow of the fluid by inserting a washing ball manufactured by US Patent No. 3,919,372 (1975, 11, 15), Japanese Patent Laid-Open No. 63-238397 (1988) , 10.4 publications), US Pat. No. 4,865,21 (1989,9,12) and others.

In addition, a cleaning apparatus for removing the scale attached to the inner wall of the fluid transport pipe installed in the condenser, known as Korean Patent Application Publication No. 1996-706061 (published on 1996, 11, 8) of the domestic international patent application, shown in FIG. As shown, a condenser 11 is connected to the inlet pipe 2 through which the fluid is introduced by the pump 1. Inside the condenser 11, a fluid transport pipe 12 installed in parallel with a plurality of fluids flowing therein, and a working fluid flow path 12 'through which a fluid such as steam or cooling gas (hereinafter referred to as "working fluid") flows. The other side of the condenser 11 is provided with a valve 21 is provided with an outlet pipe 3 through which the fluid is discharged.

The upper part of the outlet pipe (3) of the ball recovery pipe 14 is provided with a ball recovery tube 14 is formed in the cylindrical body 13 to communicate with each other and communicate with the inlet of the outlet tube (3) At the outlet, valves 22 and 23 are installed, and at the other central portion of the ball return pipe 14, the valve 24 and the check are arranged in the middle of the ball storage pipe 36, which is guided to the fluid storage device 36 to collect the washing ball 10. A conduit 15 provided with a valve 24 'is installed, and a conduit 16 provided with a valve 25 and a check valve 25' is branched to a lower portion of the inflow pipe 2 through which fluid is introduced. Under the conduit of the conduit (15, 16) of the fluid is filled in the bottom and the sieve 31 for filtering the washing ball 10 is installed in the upper portion, the fluid storage unit 32 for storing the fluid in the lower portion And a collecting part 34 serving as a ball storage part is installed on the upper part of the sieve 31 in which the tube 33 is formed, and the fluid storage in which the inlet 35 for introducing the washing ball 10 is formed. Value (36) it is provided.

One side of the fluid storage device 36 is connected to the compressor 37 for supplying compressed air by an air pipe 38 in which the electric valve 26 is installed, and the fluid storage device on the other side of the fluid storage device 36. An electric valve 39 for reducing the compressed air supplied to the 36 is connected to the drain pipe 4.

The function of Korean Patent Application Publication No. 1996-706061 (1996, 11, 8 publication) of the domestic international patent application configured as described above is a fluid transport pipe 12 is provided in a plurality in parallel in the condenser 11 In order to clean the inner wall of the pump, the pump 1 is operated to close the valve 21 installed in the outlet pipe 3 while the fluid continues to flow, and the valve 22 installed at the inlet of the ball recovery pipe 14. ) And the outlet valve 23 is opened and the timer (not shown) connected to the air pipe 38 is opened with the valves 24 and 25 provided in the conduit 15 and the conduit 16 open. When the electric valve 26 is opened by the air, the compressed air stored in the compressor 37 is supplied to the fluid storage device 36, and the fluid stored in the fluid storage part 32 of the fluid storage device 36 is supplied. Is moved upward through the pipe 33 by the pressure of the air supplied from the compressor 37 The washing ball 10 on the upper surface of the sieve 31 installed on the upper part of the male part 34 passes through the check valve 25 'and the conduit 16 in which the valve 25 is opened. 26 is automatically closed so that the compressed air applied to the fluid storage device 36 is stopped and the washing ball 10 reaches the inlet pipe (2).

As described above, the washing ball 10 reaching the inlet pipe 2 is the washing ball 10 introduced into the condenser 11 by the flow force through which the fluid flows. 11) After passing between the inner walls of each fluid transport pipe 12 installed in parallel therein, the washing ball 10 is removed from the scale attached to the inner wall of the fluid transport pipe 12, and then the outlet pipe (3). Since the valve 21 installed on the valve 21 is closed, the washing ball 10 naturally flows into the ball recovery pipe 14 through the valve 22 opened together with the fluid, and flows into the ball recovery pipe 14. The fluid is filtered through the vent formed in the cylindrical body 13 and then passed through the open valve 23 and then discharged through the outlet pipe 3.

In this way, the fluid is filtered through the vent formed in the cylindrical sieve 13 and then passed through the open valve 23 and then discharged through the outlet tube 3, while the fluid is formed in the cylindrical sieve 13 The washing ball 10 gathered at the inlet of the conduit 15 installed in the middle of the ball recovery pipe 14 by the base may operate the electric valve 39 installed at the other side of the fluid storage device 36 to operate the fluid. When the pressure in the storage device 36 is decompressed through the drain pipe 4, the washing balls 10 gathered at the inlet of the conduit 15 are removed by the pressure difference between the ball recovery pipe 14 and the conduit 15. 10 is collected through the conduit 15 through the valve 24 and the check valve 25 'and flows into the fluid storage device 36 and is collected in the ball storage on the upper surface of the sieve 31. By using the washing ball 10, the scale attached to the inner wall of the fluid transport pipe 12 installed inside the condenser 11 is removed. Will be removed.

However, in the cleaning system for cleaning the inside of the fluid transport pipe which is provided in parallel in the condenser, a conduit 15 having a diameter smaller than the diameter of the ball recovery pipe 14 is provided at the center of the ball recovery pipe 14. Since the washing ball 10 is vortexed and is not continuously collected toward the conduit 15 through the ball outlet 17 because it is installed at a right angle, there is a problem that a lot of damage and loss of the washing ball 10 occur. The fluid storage device 36 is provided by the fluid storage part 32 in which fluid is stored to transfer the washing ball 10 accumulated in the upper part of the sieve 31 installed in the storage device 36 to the condenser 11. In addition to increasing the volume of the fluid, the fluid storage device for transporting the fluid accumulated in the upper part of the sieve 31 and the washing ball 10 to the fluid transport pipe 12 installed inside the condenser 11 A separate air pipe 38 to increase the main pressure In order to recover the washing ball 10 to the fluid storage device 36 because the compressor 37 consisting of the electric valve 26 and the electric valve 39 for reducing the pressure of the compressor 37 must be installed. In order to reduce the pressure in the fluid storage device 36, a considerable amount of fluid must be discharged to the wastewater through the drain pipe 4, and the compressed air in the fluid storage device 36 for the injection of the cleaning ball 10 There is a difficulty in practical use due to the additional equipment of the compressor 37 for supply, and the scale attached to the inner wall of the fluid transportation pipe 12 is reduced due to the injection and reduction of the recovery ball by the limited capacity of the fluid storage device 36. There was a problem that the efficiency of removal is lowered.

Therefore, a gun for solving the above problems is known as registered in Korean Utility Model Registration No. 0227922 (name: fluid transport pipe cleaning device in the condenser), which is conventionally used to clean the fluid transport pipe installed in the condenser By installing a cylindrical sieve in the ball separation tube, it is possible to use the outlet tube and the ball recovery tube in a simpler configuration, and by removing the conventional compressor, the fluid storage unit installs an unnecessary ball storage tank. In order to clean the fluid transport pipe by reducing the installation cost and time and maintenance costs according to the installation, it is possible to check the flow rate of the washing ball stored in the ball storage tank with a scale and stored in the ball storage tank. Circulating pump is operated only by setting timer to set inlet pipe After discharging the washing ball, it naturally circulates by the fluid flowing through the inlet pipe. After cleaning the fluid transport pipe by the washing ball, the circulation motor is reversely rotated to recover the washing ball collected in the ball outlet to the ball storage tank. By reducing the pressure of the conduit, the washing ball is recovered to the ball storage tank through the conduit, and the cleaning ball is periodically cleaned by the fluid circulating through the fluid inlet pipe. By naturally circulating the water, the inner surface of the fluid transport pipe that transports the fluid can be efficiently cleaned and maintained.

However, many of the above-mentioned applications have a common effect of removing the scale of the inner surface by rubbing the inner surface of the fluid transport pipe while the washing ball is moving, but the sponge when contacting and cleaning the inner surface of the fluid transport pipe. Scale residues are attached to the type of washing ball, which is not equipped with the scale residue removing means to shake off the scale residues on the outer surface of the washing ball. There was a problem.

In order to solve the above problems, the cleaning ball with scale residue is strongly rubbed onto the baffle plate and sieve as a principle of cyclone, and the scale residue on the washing ball is neatly shaken to improve the cleaning efficiency of the fluid transport pipe. In addition, the connection part of the inlet pipe to which the conduit is connected is formed in the form of a venturi tube, so that the washing ball flowing in with the water into the condenser flows into the fluid transport pipe inside the condenser more rapidly, thereby improving the cleaning efficiency of the fluid transport pipe. It is a technical subject to make it possible to improve.

The present invention for achieving the above object is the inlet and outlet pipes are respectively connected to the front and rear of the condenser provided with a plurality of fluid transport pipes, the inlet pipe is connected to the fluid transfer conduit installed check valve, the outlet pipe A ball separating tube is installed at a rear end of the fluid recovery conduit, and a check valve is installed at the fluid recovery conduit, and a ball storage tank in which a sieve is installed between the fluid transfer conduit and the fluid recovery conduit to contain a washing ball.

And, the ball storage tank 30 has a drain pipe 101 having a drain valve 114 is installed at the lower end as shown in Figures 3 to 8 and the lower end has a hopper 102 pointed to the reverse conical shape A ball discharge port 104 connected to the fluid transfer conduit 18 is provided on the upper portion of the cylinder 103 to protrude upward.

In addition, a ball inlet 108 connected to the fluid recovery conduit 19 is connected to the outer tangential direction of the cylinder 103 at one upper portion of the cylinder 103, and a water inlet 105 is provided at the lower portion of the cylinder 103. Is connected in the circumferential tangential direction of the cylinder 103.

An inverted solid sieve 31 in which a plurality of washing balls 10 are inserted is installed inside the cylinder 103, and an electric valve is disposed between the inlet pipe 2 and the water inlet 105. The conduit 16 provided with the 54 and the circulation pump 42 is connected.

In addition, FIG. 7 illustrates a portion where the fluid transfer conduit 18 and the conduit 16 are connected to the “B” portion illustrated in FIG. 3, that is, the inlet pipe 2, and the tip portion of the fluid transfer conduit 18 is shown. The connection part of the side of the inflow pipe 2 connected is reduced in diameter, and forms the venturi pipe part 106.

In addition, the washing ball 10 is introduced into the inside of the cylinder 103 through the fluid recovery conduit 19 on the inner upper wall surface of the cylinder 103, the scale residue buried in the washing ball 10 is washed ball Baffle plates 107 are provided at intervals to allow them to fall off from (10).

Referring to Figures 2 to 8 the operational relationship of the present invention configured as described above is as follows.

In the cleaning ball descaling device of the condenser fluid transport pipe cleaning apparatus of the present invention configured as described above, when the scale 115 caught in the fluid transport pipe 12 of the condenser 11 is to be removed, the cylinder of the ball storage tank 30 is removed. (103) Operate the circulation pump 42 installed in the conduit 16 in a state in which a plurality of washing balls 10 are inserted into the inverted solid sieve 31 installed inside the valve 54 to open the valve 54. When the water flowing through the inlet pipe 2 is introduced into the conduit 16 by the high pressure of the circulation pump 42, the water is introduced at a high pressure.

As described above, the high pressure water introduced into the conduit 16 flows into the water inlet 105 under the cylinder 103, which is biased in the tangential direction of the cylinder 103 as shown in FIG. 6. The high pressure water connected to the inside of the tubular body 103 generates vortices along the inner wall of the tubular body 103, and the high pressure water introduced while generating the vortices acts on the inverted solid body 31 to sieve ( It flows intently through the mesh of 31).

As described above, the plurality of washing balls 10 contained in the inverted solid sieve 31 by the high pressure water flowing in between the meshes of the sieve 31 float upwards, and the fluid transfer conduit through the ball outlet 104. (18), the check valve (25 ') installed in the fluid transfer conduit 18 is opened by the pressure of the high pressure water, so the high pressure water and the washing ball (10) discharged together with the high pressure water is introduced It flows into the pipe (2) side.

When the washing ball 10 is introduced into the inlet pipe 2 together with the high pressure water, the diameter of the inlet pipe 2 connected to the distal end of the fluid transfer conduit 18 is reduced to form the venturi pipe part 106. Therefore, the flow rate of the venturi tube 106 by the principle of the venturi tube by the venturi tube part 106 becomes faster and the water in the ball storage tank 30 and the washing ball 10 are inside the condenser 11. Will be introduced at a much higher rate.

Since the venturi pipe part 106 is installed as described above, even if only the flow path on the conduit 16 side is stopped and the operation of the circulation pump 42 is opened, the ball storage tank 30 according to the principle of the venturi pipe by the venturi pipe part 106 is provided. Note that the inner water and the washing ball 10 can be introduced into the condenser 11 side.

As described above, the high pressure water and the plurality of washing balls 10 introduced into the condenser 11 at a high speed pass through the plurality of fluid transport pipes 12 installed in the condenser 11. 10 is formed in a spherical shape of the size enough to fit inside the fluid transport tube 12, as shown in Figure 2 has a sponge in the form of a cushion while tightly fitted in the fluid transport tube 12 while passing the fluid along with the high pressure water The scale 115 that is stuck to the inner surface of the transport pipe 12 is cleaned.

As described above, the washing ball 10 passing through the fluid transport tube 12 while washing the scale 115 stuck to the inner surface of the fluid transport tube 12 is inside the ball separation tube 8 as shown in FIG. 8. It is introduced into the perforated network 113, the washing ball 10 is the state in which the scale 115, which was fitted to the inner surface in the fluid transport pipe 12 is washed, so that the scale 115 is directed to the ball separation tube 8 side. While driving, the scale remains on the front circumference of the washing ball (10).

The washing ball 10 introduced into the perforated network 113 of the ball separation pipe 8 is larger than a plurality of holes of the perforated network 113, so that the washing ball 10 does not escape to the drain pipe 111 connected to the cooling tower 110, but with water The scale dregs are discharged to the drain pipe 111 through the holes of the perforating network 113.

At this time, since the check valve 24 'close to the ball separation pipe 8 is in a closed state, the washing ball 10 enters into the perforated network 113 of the ball separation pipe 8 and is stacked. When the plurality of washing balls 10 enters and piles up inside the perforation network 113 of the ball separation pipe 8, the operation of the circulation pump 42 installed in the conduit 16 is stopped by a signal of a timer. And the electric valve 54 is also closed, the ball storage tank 30 is the pressure is lowered, then the drain valve 114 of the drain pipe 101 installed on the bottom of the ball storage tank 30 by the action of the timer Opening and draining is lowered the pressure in the ball storage tank (30).

As above, when the water remaining in the ball storage tank 30 is drained through the drain valve 114 of the drain pipe 101, the scale residue contained in the water is also discharged to clean the condenser fluid transport pipe cleaning device. Naturally, the entire conduit of the ball descaling device is cleaned.

When the pressure is lowered in the path in which the washing ball 10 and the high pressure water moves as described above, since the inflow water flowing through the inlet pipe 2 is pumped by the pump 1, than when the washing ball 10 is circulated. The pressure is increased to flow into the condenser 11, the inlet pipe 2 of the condenser 11, as shown in Fig. 2 and 7 is formed with a venturi tube 106 is pumped by the pump (1) The inflow rate of is even faster.

The inflow water introduced into the condenser 11 at a high speed as described above is introduced into the ball separation tube 8 through the plurality of fluid transport pipes 12 in the condenser 11 to the inside of the ball separation tube 8. A plurality of washing balls 10 gathered in the will be pushed out to the fluid recovery conduit (19).

Since the check valve 24 ′ close to the ball separation tube 8 is opened by the pressure of the pump 1, a plurality of washing balls 10 accumulated in the ball separation tube 8 are stored. The water flows through the check valve 24 ′ and flows into the ball inlet 108 of the ball storage tank 30.

The ball inlet 108 is biased in the tangential direction of the cylinder 103 as shown in Figure 5 so that the water flowing into the inside of the cylinder 103 through the ball inlet 108 and the plurality of washing balls 10 It is introduced into the rotation while hitting the inner wall surface of the cylinder 103, the baffle plate 107 is installed on the inner inner upper inner wall surface of the cylinder 103 at intervals as shown in Figs. The washing ball 10 is introduced to the rotation while hitting the baffle plate 107.

As described above, when the plurality of washing balls 10 hit the baffle plate 107 together with the water, the scale residues buried in the washing balls 10 are hit by the impact of the washing balls when the washing balls 10 hit the baffle plate 107. 10) while falling on the inverted solid sieve 31 is placed on, and placed on the sieve 31, because the friction with the sieve 31 by hitting the sieve (31) by the inflow of water continuously introduced into the sieve (31) Even a small amount of scale residue that is buried will fall to the lower side of the sieve 31 while falling off the washing ball 10 is to be discharged to the drain pipe 101 through the lower hopper portion 102.

As described above, as the plurality of washing balls 10 pass through the inside of the fluid transport tube 12, the scale 115 caught on the inner surface of the fluid transport tube 12 is washed to clean the inside of the fluid transport tube 12. Accordingly, the heat exchange efficiency is improved, and the scale residues buried on the entire outer surface of the washing ball 10 formed in the form of a sponge in the process of washing the fluid transport tube 12 as described above are baffles of the inner wall of the cylinder 103. By washing against the plate 107 and being removed while frictionally contacting the sieve 31, the cleaning ball 10 is clean, and the next time the fluid transport pipe 12 is washed, it can be cleaned more cleanly.

As described above, the cleaning ball descaling device of the condenser fluid transport tube cleaning device of the present invention, by first rubbing the washing ball with scale residue on the baffle plate on the basis of the cyclone, and then frictionally contacting the sieve secondly. , Cleansing scale residue on the cleaning ball to clean the fluid transport pipe of the condenser cleanly, and by forming a venturi pipe in the inlet pipe in front of the condenser, the water and the cleaning ball by the fluid transport pipe of the condenser In addition to improving the cleaning efficiency of the condenser's fluid transport pipe, it is also effective to shake off the scale residues on the washing ball.
