Embodiment Construction

[0012] The present invention proposes a new method aiming at the deficiencies of the three detection methods in the current prior art. In this method, the heat transfer end difference is used as an important performance index reflecting the heat exchange condition of the condenser, and the effect of each factor on the end difference is considered comprehensively. The fuzzy modeling method is used to realize the separation of condenser fouling and the effect of working condition parameter changes on the end difference, so as to accurately monitor the condenser fouling online. It is characterized in that after thoroughly cleaning the condenser, first measure the heat transfer end difference of a given working condition, and this end difference is the end difference corresponding to the working condition in the clean state, and then change the working condition to run , and then measure the above-mentioned heat transfer end difference to obtain the change end difference between th...

Abstract

The present invention relates to a method for on-line measuring dirty extent of the condenser and its equipment. The equipment includes several sensors, signal conditioning circuit, multiway switch, DSP, in which all the sensors are connected with signal conditioning circuit and multiway switch, at the same time connected with DSP, the LED display, keyboard and communication interface are connected with DSP. It utilizes heat transfer terminal difference as researching object, duty parameter variation and fuzzy film-forming technology to accurately implement on-line measurement of the dirty extent of condenser.

Description

Technical field: [0001] The invention relates to a heat exchange tube of a condenser, in particular to a method for measuring the dirtiness of the heat exchange tube of a condenser and a device designed by the method. Background technique: [0002] Condenser is a large-scale heat exchange equipment in electric power, petrochemical and other industries. Its function is to condense the low-temperature steam after the work of the steam turbine into water to improve the efficiency of the thermal cycle. When the condenser is running, the cooling water enters from the lower part of the front water chamber, enters the rear water chamber through the cooling water pipe (heat exchange pipe), turns upward, then flows through the upper part of the cooling water pipe to the front water chamber, and finally discharges. The low-temperature steam comes in from the steam inlet, flows down through the gap between the cooling water pipes, and condenses into water after releasing heat to the pi...
