On-line leakage detection device for tube type heat exchanger

Abstract

The invention relates to an on-line leakage detection device for a tube type heat exchanger, belongs to the field of tube type heat exchanger detection equipment, mainly solves the problem of how to check whether a heat exchange tube is damaged and leaks or not when raw material gas and liquid exchange heat with a heat exchange tube in a shell for cooling, the device comprises a detection body and a hose, and a liquid inlet is set at the back of the detection body; a liquid storage chamber is arranged in the detection body, the liquid inlet is communicated with the liquid storage chamber, a pump is arranged in the liquid inlet, one end of the hose is connected with the liquid inlet, and the other end of the hose is provided with a connector. A PCB is arranged in the detection body, an amplification circuit, a filter circuit, an AD conversion circuit and a micro single-chip microcomputer are arranged on the PCB, two electrodes are arranged on the inner wall of the liquid storage chamber, and the two electrodes are connected with the amplification circuit through circuits. In the invention, the detection process is standard and reasonable, the detection result is scientific and effective, the device is small and portable, a charging mode is adopted, and the device is convenient to carry to the actual working scene of the heat exchanger.

Description

technical field [0001] The invention relates to the field of testing equipment for tube-and-tube heat exchangers, and more specifically, the utility relates to an online leak detection device for tube-and-tube heat exchangers. Background technique [0002] Column tube heat exchangers are widely used in the fields of chemical industry and alcohol production. They mainly play the role of cooling and heat exchange. The flow flows out from the outlet pipe at the other end of the head, which is called the tube side; another fluid enters through the connecting pipe of the shell and flows out from the other connecting pipe on the shell, which is called the shell side, and the fluid to be cooled It flows in the shell and exchanges heat with the water in the heat exchange tubes to achieve cooling and heat dissipation. However, during use, the number of heat exchange tubes is large, and the production quality is uneven, and the heat exchange tubes will be damaged due to When the cool...
