The inventor of the present invention has found through investigation that at present, my country has developed an energy efficiency evaluation system for dozens of products related to energy utilization and promulgated corresponding standards. However, the work on energy efficiency evaluation of heat exchangers is still in research and discussion. Now There is no equipment that can centrally detect and calculate the actual energy efficiency of heat exchangers in use, so it is very necessary to develop online energy efficiency detection equipment for heat exchangers.

The invention provides a heat exchanger energy efficiency online detection device. The heat exchanger energy efficiency online detection device comprises a flow detection apparatus, a temperature detection apparatus, a differential pressure detection apparatus and a host data processing apparatus, wherein the flow detection apparatus is adapted to detecting medium flows in hot medium and cold medium inlet pipelines, the temperature detection apparatus is adapted to detecting medium temperatures in hot medium and cold medium inlet and outlet pipelines, the differential pressure detection apparatus is adapted to detecting medium pressure differences between the hot medium and cold medium inlet and outlet pipeline, and the host data processing apparatus is connected with the flow detection apparatus, the temperature detection apparatus and the differential pressure detection apparatus and is adapted to performing processing conversion and calculation display on the detected medium flows, the temperatures and differential pressure signals. According to the invention, the heat exchanger energy efficiency online detection device can realize online acquisition of such basic data of a heat exchange as the flow, the temperature and the pressure difference, the operation and application of the heat exchange are not affected, and the heat exchanger energy efficiency online detection device is applied to rapidly determining an energy efficiency value of the heat exchange and determining the heat transfer capability of the heat exchange as a determining basis of maintenance work of the heat exchange.
Description
technical field [0001] The invention relates to the technical field of energy efficiency of heat exchangers, in particular to an online detection device for energy efficiency of heat exchangers. Background technique [0002] As an important heat energy conversion device in the development of the national economy, the heat exchanger is an energy-saving device that realizes heat transfer between materials between two or more fluids at different temperatures. Its main function is to transfer heat from a higher fluid Transfer to the fluid with lower temperature, so that the fluid temperature reaches the index specified in the process flow, so as to meet the needs of the process conditions of the industrial process, and at the same time improve the energy utilization rate of the industrial process. Among them, heat exchangers commonly used in industry are divided into plate heat exchangers and shell and tube heat exchangers. [0003] Heat exchangers are not only commonly used eq...
