The invention is suitable for the technical field of air cooling islands and provides a method and a device for calculating a steam flow during hot-state flushing of an air cooling island and terminal equipment. The method comprises the steps that test data of the air cooling island under the check working condition is obtained, and the fouling thermal resistance of the air cooling island is calculated according to the test data under the check working condition; monitoring data of a target condenser row when the air cooling island is in hot-state flushing is obtained, wherein the target condenser row is any condenser row in the air cooling island; according to the fouling heat resistance and the monitoring data, the heat exchange coefficient of the target condenser row is calculated; and the heat exchange amount of the target condenser row is calculated according to the heat exchange coefficient. According to the method provided by the invention, the steam flow in each condenser row during hot-state washing of the air cooling island can be accurately calculated according to the fouling thermal resistance of the air cooling island, and a basis is provided for control and adjustment of the hot-state washing process of the air cooling island, so that the hot-state washing time of the air cooling island is shortened, the steam consumption is reduced, the washing effect is improved, and the washing efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of air-cooled islands, and in particular relates to a steam flow calculation method, device and terminal equipment during hot flushing of air-cooled islands. Background technique [0002] The direct air-cooled unit needs to be cooled by the air-cooled island, which includes the main exhaust pipe, steam distribution pipe, condensed water collection system, elevated steel platform, auxiliary system and multiple air-cooled condenser columns, and each air-cooled condenser is composed of It consists of several cooling units with finned tube heat exchangers. There will be impurities such as rust, welding slag, and dirt on the inner surface of the pipes and heat exchangers of the air-cooled island. In order to prevent impurities from entering the condensate system, the pipes and heat exchangers must be flushed with steam before the overall start-up of the direct air-cooled unit. , remove impurities in the system. ...
