Description

Technical Field [0001] The present invention relates to an apparatus for removing internal contaminants in a sea water desalination pipe,

The present invention relates to an apparatus for removing internal contaminants in a seawater desalination pipe for an offshore plant, and more particularly, it relates to an apparatus for removing contaminants in a pipe in consideration of morphological characteristics of a pipe used in a seawater desalination plant, The present invention relates to an apparatus for removing internal contaminants in a seawater desalination pipe of an offshore plant that meets both mobility and efficiency.

Water is an essential element in life. Efforts to manage water resources such as drinking water, domestic water, industrial water, and agricultural water have been made worldwide. Despite these efforts, however, water shortages are occurring worldwide. As of 2005, about 1.1 billion people are suffering from water shortages, and by 2025, about 3 billion people will suffer from water shortages.

The Middle East and Africa are facing serious water shortages due to their environmental characteristics. However, not only in these areas but also in relatively rich areas of water, as the industrialization and urbanization progresses, the demand for water is increasing, resulting in a water shortage. Especially since 2000, demand has been increasing rapidly in most fields such as agriculture, urban use, and industrial use, and the water shortage caused by this is unavoidable.

The Earth is a water-rich planet that accounts for 70% of its surface, but most of the world's total water resources are present in seawater, and only 3% of human fresh water is available. About 70% of freshwater is glaciers and ice caps, and the number of indicators and groundwater available to human beings is less than 1% of total water resources.

It is because water is repeatedly used by the hydraulic cycle in such a small amount of water that all living things on earth including human beings can survive. However, fluctuations due to climate change and increasing water demand due to economic growth are making the supply of stable water increasingly difficult.

As a method to cope with water shortage, there is a method of reusing sewage or wastewater or using rainwater or seawater. The purification and reuse of sewage and wastewater is not a fundamental solution to the water shortage as it is a technology that increases the processing cost over time. Therefore, much attention has been focused on seawater desalination, which is a method of utilizing seawater.

Seawater desalination is a series of water treatment processes that remove high-purity drinking water, domestic water, and industrial water from sea water that is difficult to use directly for living or industrial water. Seawater desalination is also called seawater desalination, and facilities used to produce seawater as fresh water are called seawater desalination plants or seawater desalination plants.

Seawater desalination is a technology to convert seawater, which is an infinite water source, into desalination. As cost is continuously decreasing and efficiency is increasing day by day, it is regarded as a powerful alternative to fundamentally solve the water shortage problem.

In this regard, the World Future Society predicted that since 2009, seawater desalination will become one of the world's largest industries in the annual forecast report on future prospects. 112 seawater desalination projects are underway, and seawater desalination facilities are growing rapidly all over the world.

Establishment of a desalination plant for seawater desalination is being actively carried out in desert areas such as the Middle East and Africa, as well as in non-desert areas such as Singapore and South Korea. This is an important project for national security.

The seawater desalination plant is implemented in two main ways. One is a reverse osmosis system that rectifies seawater using a filter and the other is a distillation system that collects vaporized water vapor by evaporating seawater to make fresh water.

The seawater desalination plant manufactured in the above-described manner is made up of a number of pipe connections. Pipes used in seawater desalination plant facilities are important components for the inflow and outflow of seawater and the inflow and outflow of fresh water. In addition, a filter is installed inside the pipe to provide a place for removing the salt and dissolved substances contained in the seawater.

Pipes that play such an important role can be compared to the blood vessels in our body. As the blood vessels are clogged due to waste products, health problems occur. If the pipes of the seawater desalination plant are blocked due to foreign substances, the seawater and fresh water can not flow smoothly A problem arises.

Pipes, which are the core components used to install seawater desalination plants, are produced separately by a company that specializes in the production of pipes. The pipe produced in this way produces foreign matter inside the pipe during the production process, or foreign matter flows into the pipe during the transportation process. Therefore, before installing a seawater desalination plant, it is necessary to thoroughly remove any foreign matter present in the pipe.

In particular, the seawater desalination pipe installed in some offshore plant has a barrel-shaped spiral groove formed therein. These pipes generate a lot of oxidizing substances and foreign substances during the production process. Therefore, if the pipes are not removed properly, there is a problem in smoothly inflowing or discharging seawater.

Therefore, before installing the pipe, it is necessary to clean out the foreign material inside the pipe. However, the above-mentioned pipe has a length of about 12m, which is considerably long and its inside diameter is narrow, so it is difficult to remove the foreign matter inside by hand, and there is no proper equipment for it.

Several methods have been attempted at present to solve the above problems.

The first method is to remove the foreign matter by using a high-pressure injector. This is because the high-pressure spraying device is inserted into the inside of the pipe to remove the foreign material on the inner circumferential surface by using the air or water sprayed from the high-pressure spraying device, noise is largely generated in the cleaning process and the foreign substances adhering to the inner circumferential surface are removed There is a problem that it may not be possible.

The second method is to remove the foreign matter by using the robot cleaner. This is because the robot cleaner corresponding to the inner diameter of the pipe is inserted into the pipe to remove foreign matter, which causes problems such as frequent failure of the robot cleaner, low work efficiency and high initial cost.

Korean Patent No. 10-0481053 entitled "Air Injection Device for Removing Foreign Material in Pipe" and Korea Patent No. 10-1244361 "Pipe Cleaning Robot"

On the other hand, since many pipes are used in seawater desalination plants, the pipes are bundled and transported in bundles. Therefore, it must be possible to work continuously in a place where many pipes are loaded.

However, the conventional apparatuses require a compressor or a power supply for injecting compressed air or high-pressure water, which is problematic in that it is possible to work only in a limited place where the conditions are set.

At the other end of the rope guide 600, a separation preventing device 640 for covering a part of the pulley 620 is formed. The departure prevention device 640 is a device that allows the operator to lower the rope 500 spanning the rope guide 600 on the floor in the process of using the equipment for removing internal contaminants in the pipe for desalination of the offshore plant, So that the rope 500 is not released from the drawer 620 even if it is missed.

By using the rope guide 600, two workers do not form a pair, and one worker can easily remove the foreign substances inside the pipe 10 by using the equipment for removing the foreign matter of the pipe for seawater desalination by the offshore plant .

Hereinafter, an example of the use of the equipment for removing internal contaminants in a pipe for seawater desalination of an offshore plant of this embodiment will be described. Hereinafter, for the sake of convenience of explanation, the equipment for removing internal foreign matter of the pipe for seawater desalination of the offshore plant of this embodiment excluding the rope guide is referred to as the main body 20.

FIG. 10 is a conceptual cross-sectional view showing the use of the apparatus for removing internal contaminants in a sea water desalination pipe of the offshore plant of FIG. 1, FIG. 11 is a conceptual view showing an example of use of equipment for removing internal contaminants in a sea water desalination pipe of FIG. FIG.

First, the pipe 10 is placed horizontally on the floor. Thereafter, the rope guide 600 is installed at one end of the pipe 10. The rope guide 600 is rotated by one hand so that the coupling groove 610 is coupled to one end of the ring of the pipe 10 and the fixing screw 632 is turned by hand, And the engaging groove 610 of the rope guide 600 is fixed.

Thereafter, the main body 20 is positioned at the other end of the pipe 10 such that the central axis of the pipe 10 and the rotation axis of the main body 200 are aligned.

The other end of the rope 500 is inserted into the other end of the pipe 10 and is positioned so as to pass through the inside of the pipe 10 and to come out to one end of the pipe 10. The other end of the rope 500 passing through the pipe 10 to the outside is connected to the pulley 620 provided at the other end of the rope guide 600 to prevent the rope 500 from being detached by the escape prevention device 640 Install on foot. The other end of the rope 500 that has been installed in the sheave 620 of the rope guide 600 is moved to the other end of the pipe 10 along the outer peripheral surface side of the pipe 10.

The rope 500 passes through the inside and the outside of the pipe 10 to form a shape that extends over the other end portion of the pipe 10 in a 'C' shape. Since the rope guide 600 is provided at the other end of the pipe 10 and the rope 500 is hooked to the pulley 620 provided at the other end of the rope guide 600, So that the rope 500 can be easily pulled from the other end of the pipe 10. [

When the installation of the rope 500 is completed, the foreign material removing unit 400 connected to one end of the rope 500 is inserted into the pipe 10 along the central axis of the pipe 10. Since the first and second disc brushes 461 and 462 corresponding to the inner diameter of the pipe 10 are provided in the foreign substance removing unit 400, when the foreign substance removing unit 400 is inserted into the pipe 10, the first and second disc brushes 461 and 462 Is in contact with the inside of the pipe (10).

The spring wire 300 accommodated in the wire accommodating space 212 of the body part 200 is rotated about the rotation axis by rotating the body part 200 of the body 20 using the rotary knob 260 The foreign substance removing unit 400 coupled to one end of the spring wire 300 and the first and second disk brushes 461 and 462 of the foreign substance removing unit 400 simultaneously rotate around the rotating shaft. The rotating first and second disc brushes 461 and 462 rub against the inner circumferential surface of the pipe 10, thereby removing foreign matter from the inside of the pipe 10.

The spring wire 300 is a resilient material which is helically wrapped around the wire receiving space 212 but passes through the wire passage 221 of the first shaft member 220 and is pulled out to the outside, . In addition, in a state of being opened in a straight line, the rotational force of the body part 200 can be smoothly transmitted to the foreign material removing part 400 due to elasticity. Due to the characteristics of the spring wire 300, foreign matter in the pipe 10 can be smoothly removed.

The position of the foreign matter removing unit 400 inside the pipe 10 can be adjusted by pulling the other end of the rope 500 located at the other end of the pipe 10 by the operator operating the main body 20. [ The foreign matter inside the pipe 10 is sequentially removed by moving the foreign matter removing unit 400 from the other end of the pipe 10 to one end of the pipe 10.

In this process, if the rope guide 600 is not provided, the other end of the rope 500 is pulled at the other end of the pipe 10 so that the position of the foreign material removing unit 400 can not be smoothly adjusted. The rope 500 can be easily damaged due to the friction of the rope 500. [ Therefore, if there is no rope guide 600, one operator is required and the position of the foreign material removing unit 400 should be adjusted by pulling the rope 500 at one end of the pipe 10 as shown in FIG.

The spring wire 300 of the main body 20 should be caught in the wire accommodating space 212 of the main body 200 when the apparatus for removing foreign matters in the pipe for seawater desalination of the present embodiment is not used or is being transported .

By inserting the spring wire 300 into the wire accommodating space 212 and tightening the tightening screw 240, it is possible to restrict the entry and exit of the spring wire 300. That is, the spring wire 300 is easily locked by preventing the spring wire 300 from being easily pulled out. In addition, since the screw for screw tightening 241 is formed on the tightening screw 240 so that it can be easily operated by a hand, the screw 240 for screw tightening can be easily locked or unfastened without any additional equipment.
