Description

Sponge ball collector for condenser tube cleaning device}

The present invention relates to a collector that transfers or collects cleaning balls, i.e., sponge balls, when cleaning the cooling water pipe, i.e., cooling tube, of a condenser for a power plant. More specifically, the present invention relates to a collector that transfers or collects cleaning balls, i.e., sponge balls, when cleaning the cooling water pipe of a condenser for a power plant. Among the components of the Condenser Tube Cleaning System (CTCS), which removes scale, not only are the sponge balls circulated by the circulation pump collected and stored after cleaning the cooling tube, but they are also collected and stored when cleaning the tube. It is about a collector that allows the sponge balls to be transported.

In general, power plants are largely divided into nuclear power plants, hydroelectric power plants, thermal power plants, and solar power plants, and recently, combined cycle power plants are being built.

Among them, a thermoelectric power plant uses heat from combustion of fuels such as coal, oil, and natural gas to create high-temperature and high-pressure steam, and uses this high-temperature and high-pressure steam to rotate a steam turbine to produce electricity. . In the power generation facility circulation system of a thermal power plant, high-pressure/high-temperature steam generated from a boiler is supplied to a steam turbine through a supply pipe, rotates the steam turbine, and is then discharged to a condenser through a connection pipe.

The condenser used in a power plant is a device that converts the water vapor from turning the turbine back into water and supplies it to the steam generator. The principle is that the steam in the condenser is turned back into water by a tube through which cold cooling water brought in from the outside through a seawater pump flows. is hiring.

Specifically, the condenser installed in the power generation facility cools the high-pressure/high-temperature steam discharged from the steam outlet using seawater, and discharges the seawater used as cooling water through the drain, and the steam cooled within the condenser is The volume decreases, and at this time, the uncondensed steam is released into the atmosphere, and the condensed water is supplied back to the boiler through the feed pump, and then reheated in the boiler and supplied to the steam turbine, repeating the cycle.

In other words, the condenser installed in the power generation facility receives the waste steam generated when the steam turbine is running, contacts the cold cooling water pipe, that is, the outer surface of the tube, reduces the steam to water through mutual heat exchange, and supplies it back to the boiler. , This is the equipment that has the greatest impact on the electrical output and thermal efficiency of power generation equipment.

In order to exchange heat between waste steam and seawater, the condenser has hundreds to thousands of cooling water pipes, that is, tubes through which seawater flows into the waste steam, depending on the power generation capacity of the turbine.

However, because the seawater supplied to the cooling water pipe (tube) of the condenser flows only in one direction, when operated for a long time, scale occurs, such as fish and shellfish flowing into or living in the cooling water pipe. The occurrence of such scale reduces the flow rate of incoming seawater and reduces cooling efficiency.

Accordingly, the condenser uses a cleaning device to remove scale from the cooling water pipe, that is, the tube, that is, a condenser tube cleaning system (CTCS), which prevents scale from attaching to the inside of the tube, thereby suppressing scale generation. Among them, the method of removing scale by circulating cleaning balls is mainly used.

These cleaning balls are mainly made of natural rubber, butyl rubber, chloroprene rubber, styrene-butadiene rubber, urethane rubber, etc. to have appropriate flexibility, elasticity, and wear resistance. They are compressed when an external force is applied for function, and are the same as the inner diameter of the tube. It has a slightly larger diameter and removes scale as it circulates through the tube according to the flow of coolant.

At this time, the condenser uses a circulation pump to circulate the cleaning balls as described above, and this circulation pump circulates or recovers the cleaning balls. As the cleaning balls are circulated, the cleaning balls are collected through the cleaning ball recovery device. Allows you to determine the status and number of .

As described above, the cleaning balls circulated by the circulation pump are continuously worn through the scaling process, and during the circulation process, scale attaches to the surface, reducing the cleaning effect, resulting in wear or cleaning balls with scale attached to the surface. is replaced at a specific period.

To this end, the condenser uses a circulation pump to transfer and collect the cleaning balls from the ball collection unit or force them to circulate to the ball sorting and counting unit that selects and counts the cleaning balls, and the defective balls selected from the ball sorting and counting unit are transferred to the defective ball collection unit. They are collected and removed, and cleaning balls are supplied to the ball collection unit through the ball replenishment supply unit equal to the number of cleaning balls removed, thereby preventing the cleaning effect from deteriorating.

At this time, it is difficult to check the status of the cleaning balls collected inside the ball collection unit, and it is difficult to determine the problem when an internal failure occurs. To solve this problem, the conventional ball collection unit illuminates the status confirmation window and the status confirmation window together. Although the module is installed, as the lighting module is installed in the status check window, it is difficult to irradiate the light evenly inside, so there is a problem in which the status of the washing ball is not smoothly checked through the status check window.

In addition, the ball collection unit is connected to the circulation pump, the defective ball collection unit, the ball selection count unit, and the ball replenishment supply unit by screw connection or flange connection, and as a result, corrosion or the connection becomes loose over time. Not only does there exist a problem of water leakage, that is, coolant, from the connected part, but there is also a problem that work is difficult due to the large number of man-hours required when disassembling for replacement or maintenance.
