Cleaning device and optimized operation method for monitoring and cleaning the degree of dirt and corrosion inside the cooling triangular heat exchanger of the indirect air-cooled island

Abstract

The invention relates to an internal dirt and corrosion degree monitoring and cleaning device for a cooling triangle heat exchanger of an indirect air-cooling island and an optimized running method. At present, problems of large difficulty in monitoring of the corrosion degree and cleaning of internal dirt during long-term running of the cooling triangle heat exchanger of the indirect air-cooling island are difficult to solve. The device comprises a water supply pipe, the cooling triangle heat exchanger of the indirect air-cooling island and a water return pipe and is characterized by further comprising cleaning brushes, a water drainage pipeline, a water inlet pipeline, a pulsed gas-water two-phase flow cleaning device and probes; a squint window is arranged on the cooling triangle heat exchanger of the indirect air-cooling island; the cleaning brushes are connected onto the squint window; the probes are mounted on the cooling triangle heat exchanger of the indirect air-cooling island; the pulsed gas-water two-phase flow cleaning device is connected with the water inlet pipeline; the water inlet pipeline is connected with the water return pipe; and the water supply pipe communicates with the water return pipe through a pipeline. With the device, the problems of large difficulty in monitoring of the corrosion degree and cleaning during long-term running of aluminum pipes and aluminum fins of the cooling triangle heat exchanger of the indirect air-cooling island can be solved.

Description

technical field [0001] The invention relates to a cleaning device for monitoring and cleaning the internal dirt and corrosion degree of a cooling triangular heat exchanger of an indirect air-cooling island and an optimal operation method, belonging to the field of thermal power generation machinery and equipment. Background technique [0002] The indirect air-cooling unit adopts an indirect air-cooling system with a surface condenser and a vertically arranged air-cooling radiator; the ventilation facility of the air-cooling system is a reinforced concrete hyperbolic thin-shell fan cooling tower, and the radiator is arranged vertically around it. The air-cooled radiator should be composed of a cooling column (multiple rows of elliptical finned tubes or multiple rows of round tubes with large fins), the upper and lower headers of the cooling column, the exhaust or nitrogen filling pipe interface, the water inlet / outlet, and the steel structure supporting the cooling column and...
