Description

Technical Field

[0001] This utility model relates to the technical field of furnace temperature measurement devices, specifically a multi-probe mutually compensating furnace temperature measurement device. Background Technology

[0002] In the operation of a thermal power plant, heat is generated by the combustion of fuel inside the furnace, which then raises the water temperature. To ensure stable furnace operation, the furnace temperature needs to be monitored. The combustion process can be monitored by observing temperature changes within the furnace. However, the lowest temperature monitoring range of existing temperature detection devices is 400℃, which makes it impossible to effectively monitor combustion in low-temperature zones, affecting the integrity of combustion data. Therefore, improvements to existing technology are necessary. Utility Model Content

[0003] The purpose of this invention is to provide a multi-probe mutually compensating furnace temperature measuring device, which solves the problem that the combustion situation is not easy to monitor at low temperatures.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-probe mutually compensating furnace temperature measuring device, comprising a water-cooled wall, a sealing box fixedly connected to the outer side of the water-cooled wall, a probe sleeve fixedly connected inside the sealing box, a probe adjusting and fixing component installed at the right end of the probe sleeve, a high-temperature probe fixedly installed inside the left end of the probe adjusting and fixing component, and a low-temperature probe fixedly connected inside the left end of the probe adjusting and fixing component.

[0005] Preferably, the sealing box is made of aluminum alloy, which has good corrosion resistance.

[0006] Preferably, the high-temperature probe is in sliding contact with the probe sleeve, and the temperature measurement range of the high-temperature probe is 400-1600℃.

[0007] Preferably, the low-temperature probe is in sliding contact with the probe sleeve, and the temperature measurement range of the low-temperature probe is 0-400℃.

[0008] Preferably, the lower outer part of the probe adjustment fixture is bolted to a coke cleaning motor, which can be quickly disassembled by bolting.

[0009] Preferably, the right end of the probe adjustment fixture is fixedly connected to an instrument box, and the instrument box contains a signal transmitter that can transmit data signals.

[0010] Preferably, the probe sleeve is in contact with the water-cooled wall, and temperature can be transferred through the probe sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention adds a sealing box to the water-cooled wall, a probe sleeve to the sealing box, a low-temperature probe to the probe sleeve, and a high-temperature probe to the probe sleeve. During non-contact temperature monitoring, the added low-temperature probe can monitor the initial combustion temperature. The furnace temperature can be monitored using a dual-probe system with both high-temperature and low-temperature probes. Furthermore, the high-temperature and low-temperature probes can compensate for each other, resulting in more complete monitoring data and a more effective understanding of the combustion status.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 A multi-probe mutually compensating furnace temperature measuring device includes a water-cooled wall 1, a sealing box 2 fixedly connected to the outside of the water-cooled wall 1, a probe sleeve 3 fixedly connected to the inside of the sealing box 2, a probe adjustment fixing component 6 installed at the right end of the probe sleeve 3, a high-temperature probe 4 fixedly installed inside the left end of the probe adjustment fixing component 6, and a low-temperature probe 5 fixedly connected inside the left end of the probe adjustment fixing component 6.

[0017] Please see Figure 1 The sealing box 2 is made of aluminum alloy, which has good corrosion resistance. The high temperature probe 4 slides in contact with the probe sleeve 3. The temperature measurement range of the high temperature probe 4 is 400-1600℃. The low temperature probe 5 slides in contact with the probe sleeve 3. The temperature measurement range of the low temperature probe 5 is 0-400℃.

[0018] Please see Figure 1The lower outer side of the probe adjustment fixture 6 is bolted with a coke cleaning motor 7. The coke cleaning motor 7 can be quickly disassembled by bolt installation. The right end of the probe adjustment fixture 6 is fixedly connected to an instrument box 8. The instrument box 8 is equipped with a signal transmitter, which can transmit data signals.
