Description

Pipe cleaning system [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping cleaning system, and more particularly, to a piping cleaning system that cleans piping interior using wash water and high-pressure nitrogen to remove foreign matter such as scales deposited on an inner wall of piping.

Generally, a pipe serves as a passage for guiding and moving water or other fluid to a predetermined place, and is installed mainly in a form embedded in the inside of the building, the floor, or the wall. Such pipes are oxidized and corroded at the time of long-term use, and various foreign substances adhere to the inner wall surface to generate a scale. Such a scale is solidified over a long period of time and causes the pipe to be narrowed.

As the flow path cross-sectional area of the piping becomes smaller due to the scale as described above, the movement of the fluid is not smooth and the piping function as designed can not be performed. In severe cases, the piping may be damaged due to the movement pressure of the fluid.

Therefore, when a large amount of scale is generated in the piping, it is necessary to remove the scale and perform a normal role as the piping. Various techniques related to the scale removal in the piping are disclosed.

In such a conventional technique, there has been proposed a method of cleaning the inside of a pipe by discharging strong water pressure washing water into the inside of the pipe, or removing the scale inside the pipe by using a compression wave together with the water pressure. Recently, A method of cleaning the inside of the pipe by injecting compressed air is also used.

However, as the length of the pipe becomes longer, the efficiency of the pipe decreases. This is because the water pressure of the washing water injected into one side of the pipe gradually decreases in the course of the process, It falls.

In addition, although the water pressure of the washing water injected into the pipe may be increased in order to improve the cleaning efficiency of the pipe, in this case, there is a possibility that the pipe may be damaged due to the strong water pressure washing water. In the case of the deteriorated pipe, There is a problem that can happen easily.

In order to solve such a problem, a method of cleaning the inside of a pipe by using a cleaning ball that injects a cleaning ball into the inside of the pipe is also disclosed. In this conventional technique, the cleaning balls are moved inside the pipe while scraping foreign materials such as scales and discharged together with the cleaning water. The cleaning balls are injected into one end of the pipe and moved to the other end.

However, in the conventional technique using such a cleaning ball, the moving speed of the cleaning ball is lowered toward the end of the pipe, and the cleaning rate varies depending on the position inside the pipe.

[

Next, the main operation unit 100 will be described. The main operation unit 100 includes an operation body (not shown), a first flow path 110 formed in the operation body, (120), and a connection passage (160).

The first flow path 110 is connected to the high pressure nitrogen supply part 500 and the second flow path 120 is connected to the washing water supply part 400. The connection path 160 is connected to the first flow path 110 And the second flow path 120 join together and are connected to the pipe P3. The first flow path 110, the second flow path 120, and the connection flow path 160 may be formed by processing the inside of the operating body.

The first flow path 110, the second flow path 120, and the connection path 160 may be connected to the main flow path 105 formed in the operation body. That is, a main flow path 105 is formed in the operation body of the main operation part 100, and the first flow path 110 and the second flow path 120 are connected to the main flow path 105.

The second flow path 120 may be connected to the main flow path 105 at a position closer to the connection flow path 160 than the first flow path 110.

2, the high-pressure nitrogen supplied through the high-pressure nitrogen supply part 500 and the first flow path 110 moves downward (with reference to FIG. 2) through the main flow path 105, The washing water supplied through the washing water supplying part 400 and the second flow path 120 joins the high pressure nitrogen which has passed through the main flow path 105 and is moved to the connecting flow path 160. Finally, Is supplied.

On the other hand, a washing water dispersing device 300 is installed below the main flow path 105. The washing water dispersing apparatus 300 is connected to a second flow path 120 for supplying the washing water to disperse the washing water in various ways.

More specifically, the washing water dispersing apparatus 300 includes a dispersing body 320 to which the second flow path 120 is connected, a dispersing body 320 disposed inside the dispersing body 320, A wall 340, and a head portion 310. [ Here, the head part 310 is provided at the upper end of the dispersing body 320 and is in contact with the supplied high-pressure nitrogen.

At this time, the head portion 310 of the washing water dispersing device 300 is formed so as to have a smaller transverse sectional area toward the one end thereof, so that the high-pressure nitrogen contacting the head portion 310 is guided to the lower part of the washing water dispersing device 300 In the present embodiment, the head portion 310 is formed in a conical shape.

The outer diameter of the washing water dispersing device 300 is smaller than the inner diameter of the main passage 105 so that the moving space S is formed between the outer surface of the washing water distributing device 300 and the inner surface of the main passage 105. The high-pressure nitrogen passes through the moving space S and is mixed with the washing water in the lower part 350 of the washing water dispersing unit 300.

Thus, the washing water present in the washing water dispersing apparatus 300 is attracted to and discharged from the high-pressure nitrogen discharged through the moving space S. This is due to Bernoulli's theorem.

Hereinafter, a process of washing the pipe using the pipe cleaning system according to the present invention will be described.

The operator first moves the discharge pipe 190 provided in the main operation part 100 after moving the wash water supply part 400, the high-pressure nitrogen supply part 500 and the main operation part 100 to the vicinity of the pipe P3 to be cleaned, To the pipe P3 to be cleaned. The washing water supply part 400 can be contained in a compression vessel having a comparatively small size so that the operator can easily move the washing water supply part 400 and the main operation part 100. The high- Can be used.

In this state, the washing water and the high-pressure nitrogen are discharged from the washing water supply unit 400 and the high-pressure nitrogen supply unit 500, respectively, and are supplied to the main operation unit 100. This operation is performed by the first ball valve V1 and the second It can be achieved by using a ball valve V3.

The high pressure nitrogen flows along the first flow path 110 of the main operation part 100 and moves through the main flow path 105.

The high-pressure nitrogen thus moved can wash the inner wall of the pipe P3 with the washing water more effectively.

Meanwhile, the washing water flows along the second flow path 120, and the washing water flows into the main flow path 105, and is dispersed in several ways through the washing water dispersing device 300 installed in the main flow path 105. More precisely, the washing water may be supplied in the form of water droplets or in the form of a water stream depending on the interval between the dispersion walls 340 provided in the washing water dispersing apparatus 300.

Pressure nitrogen flows along the moving space S formed between the outer surface of the washing water dispersing device 300 and the inner surface of the main flow path 105 and flows into the washing water dispersing device 300 ) From below.

At this time, the head part 310 provided above the washing water dispersing device 300 is formed to have a narrow width (in the present embodiment, a conical shape) toward the front end thereof, and moves from above the washing water dispersing device 300 to a strong pressure Pressure nitrogen can be naturally guided downward by the outer surface of the inclined head portion 310.
