High-pressure water online flushing device for condenser

Abstract

The invention discloses a high-pressure water online flushing device for a condenser. The high-pressure water online flushing device comprises a transmission system and a high-pressure water flushing device, wherein the high-pressure water flushing device comprises at least one high-pressure water pump unit, a water supply pipe arranged between the high-pressure water pump unit and the condenser, a water spraying pipe communicated with the high-pressure water pump unit through a water inlet pipe and parallel high-precision nozzles arranged on the water spraying pipe; and the transmission system comprises a vertical guide rail positioned on the condenser and a sleeve arranged on the vertical guide rail in a sliding manner, and the two ends of the water spraying pipe are connected to the sleeve and move up and down along the vertical guide rail with the help of a driving device. After the high-pressure water online flushing device is adopted, work can still be carried out when the condenser is not in a halt state, so that the unit maintenance time is saved. Through adopting the high-precision nozzles, positioning is accurate. The sleeve of the transmission system regularly moves, and the flushing coverage rate of a cooling water pipe reaches 100%. The parallel high-precision nozzles simultaneously work, single flushing time is shortened, and the flushing efficiency is greatly improved.

Description

technical field [0001] The invention relates to a cleaning device for a condenser, in particular to a high-pressure water online washing device for a condenser, which is used for cleaning the cooling scale of the condenser. Background technique [0002] The main function of the condenser is to establish and maintain a high vacuum at the steam exhaust port of the steam turbine, and to use the condensed water at the exhaust steam of the steam turbine as boiler feed water to form a complete cycle. Too low vacuum in the condenser will seriously reduce the cycle efficiency of the unit and affect the safe and economical operation of the unit in the power plant. One of the important reasons for the low vacuum of the condenser is the fouling of the cooling water pipe of the condenser. [0003] The condenser cooling water pipe must be cleaned after fouling. There are three main traditional cleaning methods for condensers: manual cleaning, chemical cleaning, and rubber ball cleaning...

AI Technical Summary

Problems solved by technology

Manual cleaning is limited by the internal space of the condenser, and the work efficiency is low; chemical cleaning mainly uses acid and cleaning agents, which may cause internal corrosion of the condenser, damage equipment, and easily generate a large amount of waste water, pollute the environment, and cause Waste of funds; the recovery rate of rubber balls is low during the cleaning process of rubber balls, and inferior rubber balls are more likely to cause plugged balls, which seriously affect the heat exchange capacity of the condenser
