Optimized rubber ball feeding and cleaning system suitable for double-flow condenser of indirect cooling unit

Abstract

An optimized rubber ball feeding and cleaning system suitable for a double-flow condenser of an indirect cooling unit comprises a double-flow surface type water-cooled condenser, an optimized ball feeding system, a hot well and the like. Optimized ball inlet systems are additionally arranged in a circulating water inlet water chamber and a rotary water chamber of the double-flow surface type water-cooled condenser, so that rubber balls enter a heat exchange tube bundle of the condenser as uniformly as possible, the purpose of cleaning the heat exchange tube bundle is achieved, and the situation that the heat exchange tube bundle at a ball inlet dead zone position cannot be cleaned all the time, and the overall heat transfer efficiency of the condenser is affected is avoided. Through the implementation of the optimized rubber ball feeding and cleaning system suitable for the double-flow condenser of the indirect cooling unit, the ball feeding uniformity of the condenser rubber ball cleaning system can be optimized, and the situation that tube bundles at the dead zone position cannot be cleaned all the time, and the operation economical efficiency of the condenser is affected is avoided.

Description

technical field [0001] The invention belongs to the field of power station boiler and steam turbine systems, and in particular relates to an optimized rubber ball ball cleaning system suitable for the double-flow condenser of an intercooler unit. Background technique [0002] A condenser is a heat exchanger that condenses turbine exhaust steam into water. Condensers are mainly used in steam turbine power plants and are divided into water-cooled condensers and air-cooled condensers. The condensing equipment acts as a heat sink in the thermodynamic cycle of the steam turbine unit. Reducing the exhaust steam temperature and exhaust pressure of the steam turbine can improve the thermal cycle efficiency. 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. The condenser maintains a high ...

AI Technical Summary

Problems solved by technology

However, in actual operation, due to the dead zone in the flow field of the inlet water chamber and the rotary water chamber of the double-flow surface water-cooling condenser, it is difficult for the rubber ball to enter the heat exchange tube bank near the dead zone, so the heat exchange tube bank there is almost It cannot be cleaned, which seriously affects the cleanliness of the heat exchange tube bundle, affects the heat transfer efficiency of the heat exchange tube bundle, and affects the economical efficiency of the condenser operation
