Problems solved by technology

[0004] The traditional condensing system has the following technical problems: 1. The traditional condenser is exhausted from the top, that is, the condenser is arranged at the lower part of the steam turbine, so the steam turbine must be arranged at a certain height above the condenser, which not only increases the overhead Civil construction costs, and installation is also very troublesome; 2. The central axis of the heat exchange tube bundle of the traditional condenser system coincides with the central axis of the condenser body, the steam flow range in the heat exchange tube bundle is small, and the flow direction is uncertain, which affects heat transfer Effect, 3. The time and path of circulating water in the traditional condensing system are short, the heat exchange efficiency of the whole system is low, and the utilization rate of circulating water is low

Abstract

The invention discloses a lateral exhaust eccentric steam condensation system and method. The lateral exhaust eccentric steam condensation system comprises a steam condenser, a vacuum pump, a condensate pump, a low-pressure heater and a deaerator, wherein the steam condenser is connected with the low-pressure heater through the condensate pump; the low-pressure heater is connected with the deaerator; the steam condenser comprises a steam condenser body, a heat exchange tube bundle arranged in the steam condenser body, a water chamber arranged at two sides of the steam condenser body and an air inlet chamber arranged at the side of the steam condenser body, wherein the water chamber is connected with an exhaust duct; the central axis of the heat exchange tube bundle is parallel to the central axis of the steam condenser body; and an air extraction hole is arranged in the heat exchange tube bundle and is connected with the vacuum pump. The lateral exhaust eccentric steam condensation system has the beneficial effects that the air inlet chamber of the steam condenser is arranged at the side of the steam condenser body, so that the height of a steam turbine is reduced; and the heat exchange tube bundle is eccentrically arranged in the steam condenser body, so that the flowing uniformity of steam in the heat exchange tube bundle and the utilization efficiency of circulating water are increased.

Description

technical field [0001] The invention relates to the technical field of condensation water systems, in particular to a side exhaust eccentric steam condensation system and method. Background technique [0002] At present, the condensing system is one of the important sub-systems in the thermal system of a power plant. The condensing system provides a cold source for the entire thermal system, and plays the role of preheating and deoxygenating the boiler feed water, reducing the heat transfer of the entire thermal system. The end difference improves the exergy efficiency, and its efficiency is directly related to the power generation efficiency of the whole field thermal system. [0003] Among them, the condenser condenses the saturated steam of the steam turbine into saturated water through the heat exchange of the cooling water partition wall, so that the thermal system can recycle the condensed water, and at the same time, the non-condensable gas leaked into the thermal sys...
