Description

Cold end energy-saving optimized thermal power condenser cleaning rubber ball recovery system

Technical Field

The invention relates to the technical field of thermal power generation condenser cleaning, in particular to a cold end energy-saving optimized thermal power generation condenser cleaning rubber ball recovery system.

Background

The condenser is a key heat exchange device in a thermal power plant. In the heat exchange process, the temperature difference between the inside and the outside of the condensation pipe is large, thick water scales are easily formed in the condensation pipe, the water scales are formed by biological slime, mud scales, salt separated from a large amount of calcium and magnesium examples or impurities contained in water, and the most commonly used technology is the rubber ball online cleaning technology at present in order to solve the problem of pollution in the condensation pipe.

The rubber ball cleaning device is used as a pipeline cleaning device in the condenser, and plays a great role in ensuring the safe operation of the condenser. The ratio of the total number of recovered rubber balls to the total number of input rubber balls is called the rubber ball recovery rate (ball recovery rate for short), and the rubber ball recovery rate can comprehensively reflect the operation condition and the cleaning effect of the rubber ball cleaning device. The high ball collecting rate indicates that the device system operates normally, more balls pass through in unit time, the operation effect is good, generally, the ball collecting rate is higher than 90%, the ball collecting rate is low or is reduced rapidly and gradually, the glue ball supplement amount is increased, a cooling pipe and a ball collecting net are possibly blocked, and the cleaning effect is poor. Experience shows that the ball receiving rate is a key factor for determining the success or failure of the rubber ball cleaning, and the low ball receiving rate is the biggest obstacle for popularizing and applying the rubber ball cleaning device. The main reasons for the low ball collection rate are: the ball collecting net is blocked by circulating water impurities, so that part of the rubber balls float on the water surface and cannot be recycled; the aging of the ball collecting net causes untight closing and ball leakage.

Ball receiving nets have been developed rapidly as a key device for cleaning rubber balls, and have gone through 3 generations. Wherein, the first generation is a fixed ball receiving net; the second generation is a movable grid type ball collecting net with an upper ball collecting net and a lower ball collecting net; both generations of ball collecting net products are obsolete and are no longer used by most power plants. At present, the ball collecting net used in most power plants is a third generation ball collecting net and is arranged in an inverted V shape.

However, the following technical problems have been found after using this technique:

1. the filter screen that the rubber ball was retrieved is easy to be blockked up. The back is accomplished in the washing of rubber ball, can be retrieved a service ball section of thick bamboo, when retrieving through the filter screen, because the rubber ball is discharged together with the water that washs in the cooling tube, the jam of current filter screen is caused easily in the impurity of former cooling water and the impurity combination that washs out, needs the manual work to go clean the scrubbing regularly. The filter screen that blocks up simultaneously can lead to the drainage not smooth to cause and receive interior ponding of ball bucket, and then leads to the glueballs to float and can't normally receive the ball on the surface of water (present net structure is arranged like the type of falling V, sets up out the ball mouth and receives the ball in the net bottom of the font both sides of falling V).

2. The structure of current ball receiving net also causes the foreign matter such as impurity greasy dirt in the cooling water to bring into dress ball bucket easily, when carrying out the circulation washing again, is brought into the condenser pipe and influences the cleaning performance, causes the card ball.

3. The size of the rubber ball is slightly larger than the diameter of the cooling pipe, and after the rubber ball is used for a period of time, the rubber ball is influenced by friction, and the size of part of the rubber ball cannot meet the requirement of cleaning, but is not screened out in time, so that the cleaning effect is increasingly poor.

4. After the clean cooling tube of rubber ball, the water in the cooling tube is discharged together with the rubber ball, the discharged water is more except impurity, the temperature has also risen 11 degrees, we call hot water here, after the rubber ball is retrieved, this part hot water is brought into the ball sending section of thick bamboo, and follow the pipeline and pump the condenser once more in, this part hot water is less than the water yield that gets into in the condenser cooling tube for the first time relatively, according to statistics, still can promote the temperature 0.07 degree that gets into the cooling tube water for the first time, the cooling water that risees can lead to condenser work efficiency to reduce, consume more fire coal. For example, when a unit condenser with a load factor of 90%, operating for 5500h every year and a power of 680MW is fouled to reach a thickness of 0.5mm, the coal consumption during power generation is increased continuously, the coal consumption per year is increased by over thirty thousand tons, and if the coal price is calculated according to 1 ton of 500 yuan, the increased cost is over 1800 ten thousand yuan. If the thickness of the scale reaches 1mm, the consumption of coal can reach about 50000t, and the power generation output is reduced by about 10%, so that the cleaning rate of the condenser determines the back pressure of the steam turbine, and the economical efficiency of a unit and the discharge amount of pollutants are determined.

Therefore, a cold end energy-saving optimized thermal power generation condenser cleaning rubber ball recovery system is provided for solving the problems.
