Cold side energy saving optimization thermal power generation condenser washing system

Abstract

The invention discloses a cold side energy saving optimization thermal power generation condenser washing system. The washing system comprises a condenser and an outer pipeline. A conical mesh screenis fixedly mounted in the outer pipeline, the conical mesh screen is movably connected with a rotary mesh barrel, a slewing bearing is fixedly arranged on the outer side wall of the rotary mesh barrel, a supporting outer ring engaged with a gear drive device is arranged on the slewing bearing, the rotary mesh barrel is of a curve type structure, and the outlet end of the rotary mesh barrel is located at the water inlet ends of cooling pipes. Rubber balls and water currents are introduced from one end of the conical mesh screen and discharged into the rotary mesh barrel from the other end, as the rotary mesh barrel is driven by the gear drive device to radially rotate in the outer pipeline, when the inlet end of the rotary mesh barrel rotates, while the outlet end of the rotary mesh barrelrotates by itself, the outlet end can carry out revolution around the central axis of the inlet end, and therefore when pushed by the water currents to be discharged from the outlet end of the rotarymesh barrel, the rubber balls can evenly enter the cooling pipes in the condenser.

Description

technical field [0001] The invention relates to the technical field of on-line cleaning of condensers, in particular to a cold-end energy-saving optimization thermal power generation condenser cleaning system. Background technique [0002] Condenser is the key heat exchange equipment in thermal power plant. During the heat exchange process, the temperature difference between the inside and outside of the condenser tube is very large, and thick scale is easy to form in the tube. These scales are composed of biological slime, mud, salt precipitated from a large amount of calcium and magnesium, or impurities contained in water. In order to solve the problem of contamination in the condensation pipe, the most commonly used technology is the on-line cleaning of rubber balls. This technology can clean the condensing pipe online without stopping the turbine, which greatly improves the power generation of thermal power plants. [0003] After using this technique, it was found that...

Problems solved by technology

Therefore, the phenomenon of uneven and incomplete cleaning of the condenser tube has not been fundamentally changed due to the substantial increase in the pitching rate

[0006] For example, when the condenser scale of a unit with a load rate of 90%, an annual operation of 5500h, and a power of 680MW reaches 0.5mm, the coal loss during power generation will continue to increase, and the annual coal consumption will increase by three times. More than 10,000 tons, if the coal price is calculated at 500 yuan per ton, the increased cost will be more than 18 million yuan
