Online heat exchanger performance detection system

Abstract

The invention discloses an on-line heat exchanger performance detection system. The on-line heat exchanger performance detection system includes a cold water preparation section, a cold water heat absorption section and a hot water heat dissipation section; the cold water preparation section comprises a cold water tower, a cold source water tank, a cold source pump and the like; the heat emission side of a cold water heat exchanger of the cold water heat absorption section is sequentially connected with a cold water tank, a cold water pump, a cold side pressure sensor, a clod side inlet temperature sensor and the heat absorption side of a heat exchanger product requiring detection through pipelines; the heat emission side outlet of the heat exchanger product at the hot water heat dissipation section is sequentially connected with a heat side outlet temperature sensor, a heat side pressure sensor, a heat side flow meter, a hot water tank, a cold water pump, an electric heater and a heat side inlet temperature sensor through pipelines; and a field controller and a workstation are connected with each other through a network cable and by means of TCP-MODBUS so as to communicate with each other. According to the on-line heat exchanger performance detection system of the invention, operation monitoring conditions are provided for the heat exchanger through a traditional industrial control principle, and a mobile phone monitoring function and a report pushing function are prepared for a user finally.

Description

technical field [0001] The invention belongs to the field of heat exchangers, and in particular relates to an online heat exchanger performance detection system. Background technique [0002] At present, with the rapid development of my country's petrochemical, steel and other industries, the demand for heat exchangers continues to grow. The specific heat transfer performance of heat exchangers has always been a factor that heat exchanger manufacturers and end users focus on. However, due to the lack of testing methods, some heat exchangers produced cannot be fully verified before leaving the factory, which makes the quality of heat exchanger products, especially non-standard customized products, unguaranteed. At present, there are also some experimental devices for its detection in China, which monitor some important parameters of the endothermic and exothermic sources and the process, and finally form reports and conclusions to verify the performance of the product.

Problems solved by technology

[0003] However, there is a shortcoming of the results detected by the traditional experimental system, that is, the data can be changed manually after the report is formed, which greatly reduces the authenticity of the report and is prone to fraudulent situations. Customers often need to go to the experimental site to supervise the experiment in person to rest assured
