Abstract

The invention discloses a temperature control method of an air cooling condenser, and belongs to the field of condenser freezing prevention. According to the temperature control method provided by theinvention, air regulating devices of a plurality of cooling triangular units distributed on the 1 / 6-1 / 8 circumference of the windward side and the circumference circumference which is in central symmetry with the windward side are closed one by one according to the influence of the ambient wind on the heat dissipating capacity of air-cooled condenser at different positions around a tower when thetemperature of a condensation water pipe is lower than a set value, and steam inlet pipe valves of the cooling triangle units are closed, so that the temperature of condensation water can be rapidlyincreased, the heat dissipation amount of a heat dissipation unit is balanced, and the freezing risk is reduced; and when the temperature of the condensation water pipe of the air cooling condenser ishigher than a set value, the steam inlet pipe valves of a group of cooling triangle units distributed on the windward side and the circumference which is in central symmetry with the windward side are opened one by one, and then the opening degree of the air adjusting devices corresponding to the cooling triangle units is gradually increased until all the cooling triangle units are put into operation according to the steps or the temperature of the condensation water pipe is lower than the set value, the condensation water temperature is stably reduced.

Description

technical field [0001] The invention belongs to the field of condenser antifreeze, in particular to a temperature control method of an air-cooled condenser. Background technique [0002] The natural ventilation direct air-cooling system is that the exhaust steam of the steam turbine is sent to the air-cooled condenser through the exhaust pipe. The surface of the condenser, so that the steam in the condenser is condensed. One of the main factors affecting the operation of the air-cooling system in winter is that when there is a strong wind in the environment, because there is no large amount of water volume buffer in the air-cooled condenser, the condenser tube bundles will freeze and block quickly, causing the finned tubes of the condenser to deform or freeze. , causing permanent damage. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming that the air-cooled condenser is easy to freeze and crack in the existing natural v...
