Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internal wear management system and method for a transfer facility using ultrasonic inspection,

The present invention relates to an internal wear management system and method for a transfer facility using ultrasonic flaw detection, and more particularly, to a transfer facility provided in a thermal power plant, specifically, a transfer pipe for ash generated after combustion or a conveyor belt facility The chute liner on the chute liner is inspected in the non-destructive type through the ultrasonic flaw detector, and the internal wear state generated in the transfer facility, that is, the wall-thinning state is measured using the inspection information obtained through the inspection And more particularly, to an internal wear management system and method of a transfer facility using ultrasonic inspection capable of managing the internal wear.

Non-destructive Testing (NDT) is a method of inspecting defects such as pores or cracks in interior parts of various industrial products or defects in welds from outside without changing the shape or function of the product. Ultrasonic Testing (UT), Magnetic Particle Test (MT), Liquid Penetrant Testing (PT), Eddy Current Testing (ECT) , Leak Testing (LT), or Acoustic Emission Testing (AET).

The "ultrasonic inspection test" is a method of detecting a defect existing in a sample by applying ultrasonic waves of a high frequency band (1 to 25 MHz) to the sample and analyzing signals of ultrasonic waves reflected from defects existing on the surface or inside of the sample Inspection method.

Specifically, the ultrasonic wave propagates straight in the same medium (sample), but is reflected or refracted by the difference in the physical state and properties of the medium, that is, the acoustic impedance at the interface with other medium (defective area such as voids formed in the sample) The ultrasonic wave is applied to the sample through the probe, the reflected ultrasonic wave is received through the probe, and the ultrasonic wave is displayed on the display unit of the flaw detector in the form of a pulse signal to measure the position, type and size of the defect.

The apparatus for performing the ultrasonic inspection includes a transducer for generating ultrasonic waves, a receiver for receiving ultrasonic signals reflected from internal defects of the sample, a display for displaying the received signals as pulse signals, And a liquid supply device for providing a medium for ultrasonic signal transmission. In recent years, however, the probe and the receiver may be constituted by a single ultrasonic sensor or in the form of a probe unit including the liquid supply device.

On the other hand, among the coal-fired power plant facilities, there are many transport facilities vulnerable to internal wear, and in particular, our dry transport pipelines and transport liners that handle coal are representative.

First, a transfer pipe used for the dry sub-process will be described in detail.

The method of treating and transferring ash generated after combustion to a coal-fired power plant is largely classified into a dry treatment method using a blower and a wet treatment method using seawater, and the hardness and abrasion resistance are very high Because it is a material, cast iron piping is usually used which is known to have a long-term service life.

However, in such a cast iron pipe, too, there is serious wear of the cast iron pipe due to abrasion of the mixed water caused by direct abrasion or wet treatment during casting, and wall-thinning of the cast iron pipe due to abrasion Failure to do so may cause malfunctioning of peripheral equipment or serious environmental pollution, depending on the burning.

However, preventive maintenance is difficult due to the lack of cumulative data on pipe wear. Economic losses are also present, such as the cost of selling off due to leakage, or additional landfill costs.

In order to prevent such a problem, conventionally, rather than repairing damaged pipes, the damaged parts are replaced. In the case of the transfer pipe, the portion vulnerable to internal wear is composed of many bends and is easy to replace Since the entire length is too long to predict the breakage section, it is difficult to secure the material for a specific section. Also, since the supply capability of the domestic cast iron pipe supplier is small and insufficient, There is a problem that the supply and demand of materials is very difficult.

Next, a concrete liner on a conveying facility for handling coal will be described in detail.

The fuel used in the coal-fired power plant carries coal from the coal-specific pier, carries it through a conveyor belt, and then transports it back to the cargo conveyor belt through the Stacker Reclaimer to supply it to the boiler. , Where coal is passed through a large number of suitliners.

Since the fuel to be carried is composed of many mixtures such as coal, gravel, and carburizing, it can cause severe wear and it is difficult to visually check the wear state of the interior due to the nature of the suitliner, It is practically impossible to check the cracks before the naked eye confirms cracks such as the damage and the discharge of coal. Thus, this poses a serious risk to the stability of the facility.
