Abstract

The invention provides a self-starting and stopping method of washing of a rubber ball of a condenser based on a DCS. The method includes the steps that the condenser circulating water cleaning coefficient is preset in the DCS, the condenser working condition data is collected, and by using the collected condenser working condition data, and the actual cleaning coefficient of the condenser circulating water side is calculated through the DCS configuration; and the preset cleaning coefficient Mu0 is compared with the actual cleaning coefficient Mu, and the control signal is sent to start / or stop a washing system of the rubber ball. Through the DCS control, the remote start and stop of the washing system of the rubber ball of A and B sides of the condenser circulating water from an existingsystem flow, the investment is low, the construction condition is easy to realize, and the information such as the cooling water flow, flow rate, pressure, and temperature of a condenser chamber can be mastered in real time.

Description

technical field [0001] The invention belongs to the technical field of cooling water, and in particular relates to a DCS-based self-starting and stopping method for cleaning rubber balls of a condenser. Background technique [0002] Condenser is a large-scale heat exchange equipment used in electric power, pharmaceutical, chemical and other industries. Its heat exchange performance directly affects the utilization rate of energy, which is related to the energy saving and emission reduction of the factory. Because the condensers used in the industrial field are usually water-cooled, the natural water directly taken from rivers and lakes is not clean, and the heat exchange is accompanied by chemical reactions, resulting in the accumulation of some dirt on the inner wall of the copper tube that is not conducive to heat transfer, making the condenser The heat transfer capacity of the heat exchange surface is greatly reduced, which in turn reduces the efficiency of the steam turb...
