PLC200based on monitoring of dual-chamber heat exchanger
Abstract
Monitoring circulating cooling water heat exchanger，also known as monitoring，monitoring device is installed in the field.To monitor the system in the cooling tower corrosion and fouling situation.Location Monitoring of the heat exchanger in the cooling tower is generally close to the return pipe line，sometimes with emphasis cooler mounted in parallel.With the increasing scarcity of water resources，To conserve water，More practical use of water recycling methods，with recirculating water concentration times shrink improvement of water quality monitoring requirements are also increasing.The current water quality monitoring equipment，mainly to monitor the main heat exchanger，heat exchanger with a good monitor，strengthen the monitoring of water quality，is becoming increasingly important.
In this paper，Siemens S7-200PLC and Kingview monitor dual-chamber heat exchanger system，a distributed control system architecture，complete on-site data collection，automatic control functions.The system of traffic control needs，a fuzzy PID controller for flow control，improve the flow control effect.Human-machine interaction，and high reliability，strong anti-jamming capability.
