Description

TECHNICAL FIELD

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

[0002] The heat exchanger monitoring device is a device for detecting the working state of the heat exchanger. The plate heat exchanger is a device for heat exchange 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 change of the inflowing cold liquid and hot liquid and the outflowing cold liquid and hot liquid of the plate heat exchanger has a certain feedback effect on the working condition of the plate heat exchanger.

[0003] The existing monitoring device has the following defects:

[0004] 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 at different positions of the pipeline of the heat exchanger. When different heat exchangers are replaced, the position of the pipeline on the heat exchanger inside the monitoring device will change. Therefore, a heat exchanger intelligent monitoring device based on the Internet of Things with video monitoring and temperature monitoring at different positions of the pipeline of the heat exchanger is needed to solve this problem.

[0005] 2. The 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 the temperature sensor. When different plate heat exchangers are replaced, the distance between the pipelines of the plate heat exchanger will generally change. When the distance between the two temperature sensors cannot be changed, the temperature of the pipeline on the different heat exchangers cannot be monitored. Therefore, a heat exchanger intelligent monitoring device based on the Internet of Things is needed to adjust the distance of the temperature sensor for monitoring the temperature of the pipeline of the heat exchanger according to the distance between the pipelines of the heat exchanger to solve this problem.

[0006] 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 collision between the temperature sensor and other objects can also cause injury to other objects. Therefore, a heat exchanger intelligent monitoring device based on the Internet of Things is needed to protect the up-and-down moving temperature sensor to solve this problem.

[0007] 4. The prior art CN108692608A discloses a heat exchanger operation condition intelligent online monitoring device, which does not have a structure for cleaning the dust on the outer wall of the pipeline of the plate heat exchanger. When dust adheres to the outer wall of the pipeline, the temperature of the fluid in the plate heat exchanger is easily covered by the dust, causing the temperature sensor to be unable to effectively detect the temperature of the outer wall of the pipeline. Therefore, a heat exchanger intelligent monitoring device based on the Internet of Things is needed to solve this problem. SUMMARY
