Description

Technical Field

[0001] The invention belongs to the field of boiler high temperature corrosion detection, and in particular relates to a wall-type tangentially-shaped boiler high temperature corrosion detection control device and a use method. Background Art

[0002] The wall-type tangential boiler high-temperature corrosion detection and control device is a device specially used to monitor and control the high-temperature corrosion of the boiler water-cooled wall. Its core function is to achieve effective monitoring and control of high-temperature corrosion by setting up multiple layers of primary air burners and secondary air inlets, as well as flue gas measurement sampling points on the boiler water-cooled wall, thereby improving the safety and stability of the boiler.

[0003] The wall-type tangential boiler high temperature corrosion detection and control device currently on the market has the following problems when used: 1. The traditional wall-type tangential boiler high temperature corrosion detection and control device is inconvenient to repair during the actual maintenance process because the equipment body is relatively large and has an integrated structure. Once a fault occurs inside the equipment body, subsequent maintenance is difficult; 2. When most wall-mounted circular boiler high-temperature corrosion detection and control devices are used, it is often necessary to move the probe to the inside of the equipment body for detection. Since the wiring harness is relatively long, the staff will directly pile it on the ground and continue to take it when it is used next time, so the effect of wiring harness storage is poor during application; 3. When using most wall-mounted circular boiler high-temperature corrosion detection and control devices, it is usually necessary to install the wiring harness on the outside of the equipment body. However, long-term use can easily cause the wiring harness to wear out, resulting in inaccurate collected data, so the sealing effect is weak during use. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned disadvantage of great difficulty in maintenance and to provide a high temperature corrosion detection and control device for a wall-type tangentially-shaped boiler and a method for using the same.

[0008] A further improvement of the present invention is that a second wire harness is provided on the other side of the support frame, a probe is provided on the other side of the second wire harness, and a detector is installed outside the first wire harness.

[0009] A further improvement of the present invention is that the bottom of the support frame is connected to the base, the bottom of the base is provided with a rod body, the bottom of the rod body is provided with a seat body, and the bottom of the seat body is equipped with moving wheels.

[0010] A further improvement of the present invention is that a sealing groove and a threaded hole are provided on the side of the equipment body, a sealing ring is embedded in the sealing groove, and a fastening screw is threadedly connected to the threaded hole.

[0011] In a second aspect, the present invention provides a method for using a high temperature corrosion detection and control device for a wall-type tangentially-shaped boiler, comprising the following steps: Move the support frame to the outside of the boiler and adjust the length of the second harness; Adjust the probe on the side of the second harness, and then install the control device body; Start the device body, connect the first wire harness with the second wire harness, and view the value outside the detector; After the boiler high temperature corrosion test is completed, the wiring harness and the control device body are disassembled.

[0012] A further improvement of the present invention is that when the support frame is moved, the moving wheel is pulled to move the probe, the probe is placed inside the boiler, and the control device body is mounted on the outside of the boiler using fasteners.

[0013] A further improvement of the present invention is that when high temperature corrosion detection is performed, the data displayed on the outside of the detector needs to be recorded in real time.
