Description

Technical Field

[0001] The present invention relates to the technical field of heat exchanger monitoring, and in particular to an intelligent heat exchanger monitoring device based on the Internet of Things and a use method thereof. Background Art

[0002] Heat exchanger monitoring equipment is a device that detects the working status of the heat exchanger. Plate heat exchanger is a device that exchanges heat between cold liquid and hot liquid. Heat exchanger monitoring generally refers to monitoring the temperature and pressure of the internal fluid of the heat exchanger. The temperature changes of the cold liquid and hot liquid flowing into the plate heat exchanger and the cold liquid and hot liquid flowing out of the plate heat exchanger have a certain feedback effect on the working condition of the plate heat exchanger.

[0003] The defects of existing monitoring equipment are: 1. The prior art JPH1086144A discloses a method for monitoring a heat exchanger. This technology does not have a structure for simultaneously monitoring the working video of the heat exchanger and the temperature of different positions of the heat exchanger pipe. When replacing different heat exchangers, the position of the pipe on the heat exchanger inside the monitoring device will change. Therefore, an IoT-based heat exchanger intelligent monitoring device with video monitoring and temperature monitoring of different positions on the heat exchanger pipe is needed to solve this problem.

[0004] 2. Prior art JP2016080286A discloses a heat exchanger monitoring device and a heat exchanger monitoring method. This technology does not have a structure for adjusting the position of a temperature sensor. When a different plate heat exchanger is replaced, the distance between the pipes of the plate heat exchanger generally changes. When the distance between the two temperature sensors cannot be changed, the temperature of the pipes on different heat exchangers cannot be monitored. Therefore, an IoT-based heat exchanger intelligent monitoring device is needed to solve this problem. The device can adjust the distance of the temperature sensor that monitors the temperature of the heat exchanger pipe according to the distance between the pipes of the heat exchanger.

[0005] 3. The prior art US06241383B1 discloses a heat exchanger maintenance monitoring instrument and method. This technology does not have a structure for protecting the temperature sensor. When the height of the temperature sensor can be changed, the moving temperature sensor cannot be protected. At the same time, the temperature sensor collides with other objects and easily causes damage to other objects. Therefore, an IoT-based heat exchanger intelligent monitoring device that can protect the temperature sensor that moves up and down is needed to solve this problem.

[0006] 4. Prior art CN108692608A discloses an intelligent online monitoring device for the operation status of a heat exchanger. This technology does not have a structure for cleaning the outer wall of the pipe of the plate heat exchanger. When dust adheres to the outer wall of the pipe, the temperature of the fluid inside the plate heat exchanger transferred to the pipe is easily covered by the dust, causing the temperature sensor to be unable to effectively detect the temperature of the outer wall of the pipe. Therefore, an IoT-based intelligent heat exchanger monitoring device that can clean the dust on the outer wall of the pipe of the plate heat exchanger is needed to solve this problem.
