Problems solved by technology
Therefore, the process simulation software cannot accurately calculate the parameters such as the circulating water flow rate, pressure drop and fouling thermal resistance of the water cooler
[0005] Secondly, there are also deficiencies in the working method of calculating the operation status of the water cooler on the computer platform.
Due to the large number of enterprise information systems, accounting through the computer platform requires the installation of relevant computing software or the development of relevant information systems. The manual development workload is heavy and the cost investment is high, and often due to the heavy workload of enterprise technology or management personnel, the water cooling on the computer platform The timeliness of logging in and checking the accounting results of the operating status of the water cooler is poor, which makes the timeliness of the on-site management of the water cooler insufficient.

Embodiment 1
[0070] The structural parameters of the water cooler are as follows:
[0071]
[0072]
[0073] DCS display parameters: flow rate of process side inlet water cooler is 28.45t / h, pressure is 1.1MPa, temperature before cooling is 58.4°C, temperature after cooling is 39.4°C, temperature of circulating water inlet device is 26.2°C, pressure is 0.4MPa. The measured circulating water temperature after changing is 33.5°C.
[0074] The conventional software accounting results are as follows:
[0075] The above data is entered into the process simulation software through the database or manually, and the relevant parameters are calculated. First, calculate the circulating water flow rate of 75.82m3 / h according to the heat balance, and then simulate other results such as the flow rate of the tubes on the circulating water side of the water cooler is 0.95m / s, the pressure drop of circulating water entering and leaving the water cooler is 19.67kPa, and the thermal resistance of dir...

Description
technical field [0001] The invention relates to the field of petrochemical processing, in particular to an on-line detection system and detection method for water coolers. Background technique [0002] In order to control the temperature of the process medium after exchange, the petrochemical plant is equipped with a circulating water cooler. Under normal circumstances, thermocouple thermometers are installed when the process medium enters and exits the water cooler, and thermocouple thermometers and remote pressure gauges are not installed for circulating water entering and exiting the water cooler. The circulating water cooler is used as auxiliary equipment, and the management is relatively extensive. As long as the temperature of the process medium after cooling can meet the process index requirements, the operation of the water cooler will not be adjusted generally, and it is impossible to grasp the operating status of the water cooler in real time, such as the flow rate...
