Description

Pipeline cleaning system {Pipeline cleaning system}

The present invention relates to a conduit cleaning system, and more particularly, to a conduit cleaning system capable of cleaning the inside of a conduit using a slush generated by cooling a fluid.

As a background art, a process known as Pigging is to clean the inside of a pipeline by scraping or pushing off residues on the inside of a pipeline of processing equipment, and is well established in the field of oil or gas recovery and distribution. The process involves pushing a pig, a solid or device shaped to fit inside the conduit, into the conduit under pressure.

As a conventional pig process, there is a method of removing scale inside the pipe by inserting a scraper or brush into the pipe. However, in the pig process using a scraper or brush, it is difficult to pass through irregularities or bends that sometimes exist in the pipeline, such as welded joints of the pipeline, without damage, and the cleaning efficiency of the pipeline is poor.

Accordingly, a pig formed in a spherical or bullet shape is advanced with high-pressure water to remove scale inside the pipe while passing through irregularities or bends of the pipe without damaging it, and a method of removing scale inside the pipe with the frictional force of the pig and solid ice. It is proposed to use bullets. Among them, the pig process using the solid bullet of ice has the advantage that the solid bullet of the pig-in ice does not cause any harm over time and decomposes itself even if the pipeline is blocked during movement.

The prior art of the pig process using such a solid bullet of ice is Korean Patent Registration No. 10-0786148 "In-pipe washing and separation method", in which crushed ice aggregates in a wet state are pumped through a pipe, and the crushed ice An in-pipe cleaning and separation method has been disclosed in which a pipe wall is cleaned using agglomerates and crushed ice agglomerates are pushed out of the pipe for recovery.

However, the prior art controls (sets) the ice particle size of the ice aggregate, which is slush ice or crushed ice, to 5 mm or less to be suitable for use in food processing machinery, and freezes and crushes ice to control the particle size of ice (crushing), there is a problem in that the configuration of the system becomes complicated because the ice crushing device and the water separation device for separating the water generated by crushing the ice must be separately configured.

In accordance with these problems, the present invention intends to develop a pipeline cleaning system that can easily clean pipelines by generating optimal slush for washing pipelines without ice breaking and water separation.

When the crystals are not significantly formed, slush, which is intermediate between liquid and solid, is generated. Among them, as a method of cooling the fluid, there is a first method of generating slush by lowering the cooling temperature, and in another method, after cooling the fluid rapidly to a metastable supercooled state, disturbance ( Example: shock, vibration, high pressure release, etc.) is applied to generate an instantaneous phase change, thereby generating a slush having a relatively smaller particle size than the first method.

The pressure and cooling means is the first method so that the agitator and freezer 100 does not rapidly cool the fluid, but continuously stirs through the stirring blades 120 while cooling the fluid to generate slush. It is applied to adjust the cooling temperature of the chamber 110.

In addition, the chamber 110 discharges the slush generated inside to one side. At this time, one side of the chamber 110 may be preferably the lower side, and the slush discharged to the lower side is put into the pipe 1 A first discharge pipe 113 providing a discharge path is provided.

That is, when the fluid or slush is accommodated in the chamber 110, since the cleaning process of the conduit 1 is a process of the first step, the LED for displaying the first step is turned on or off or the first step An icon of the step may be output on the display.

The memory unit 600 stores information about the internal pressure and cooling temperature of the chamber 110 for each strength and particle size of the slush that can be selectively controlled through the input unit 500 .

The memory unit 600 transmits information about the strength of the slush input from the input unit 500 and the pressure and cooling temperature inside the chamber 110 for each particle size to the control unit 300. At this time, the control unit 300 ) determines (or analyzes) the information on the pressure and cooling temperature inside the chamber 110 received from the memory unit 600, and then transmits a control signal to the pressure and cooling means of the chamber 110 The pressure and cooling temperature inside the chamber 110 are set.

The first sensor unit 700 is installed inside the chamber 110 to measure the pressure and cooling temperature inside the chamber 110, which are set as the pressure and cooling means, respectively, and the measured chamber 110 Information about internal pressure and cooling temperature is transmitted to the controller 300 .

The control unit 300 determines the pressure and cooling temperature inside the chamber 110 based on the information about the pressure and cooling temperature inside the chamber 110 received from the first sensor unit 700, and The operation of the pressure and cooling means is controlled so that the pressure and cooling temperature inside the chamber 110 reach the pressure and cooling temperature inside the chamber 110 input through the input unit 500 .
