Description

Technical Field

[0001] The invention relates to the technical field of furnace temperature measuring devices, and in particular to a multi-probe mutual compensation type furnace temperature measuring device. Background Art

[0002] During the operation of a thermal power plant, heat is generated by the combustion of fuel inside the furnace, and then the water temperature is raised by the heat. In order to ensure the stable operation of the furnace, the temperature of the furnace needs to be detected. The combustion of the fuel can be monitored by the temperature change inside the furnace. However, the minimum temperature of the temperature monitoring range of the temperature detection device in the prior art is 400°C, which makes it impossible to effectively monitor the combustion in the low temperature zone, affecting the integrity of the combustion data. Therefore, the prior art needs to be improved. Summary of the invention

[0003] The purpose of the present invention is to provide a multi-probe mutual compensation furnace temperature measuring device, which solves the problem that the combustion condition is inconvenient to monitor at low temperature.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a multi-probe mutual compensation furnace temperature measurement device, comprising a water-cooled wall, a sealing box is fixedly connected to the outside of the water-cooled wall, a probe sleeve is fixedly connected to the inside of the sealing box, a probe adjustment fixture is installed at the right end of the probe sleeve, a high-temperature probe is fixedly installed at the left end of the probe adjustment fixture, and a low-temperature probe is fixedly connected to the left end of the probe adjustment fixture.

[0005] Preferably, the sealing box is made of aluminum alloy material, 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°C.

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

[0008] Preferably, a defocusing motor is mounted on the lower outer side of the probe adjustment fixture via bolts, and the defocusing motor can be quickly disassembled by means of the bolt mounting.

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

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

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention adds a sealing box to the water-cooled wall, adds a probe sleeve to the sealing box, adds a low-temperature probe to the probe sleeve, and adds a high-temperature probe to the probe sleeve. In the process of monitoring the temperature in a non-contact manner, the initial temperature of the combustion can be monitored by the added low-temperature probe. In the monitoring process, the furnace temperature can be monitored in a double-probe manner formed by a high-temperature probe and a low-temperature probe. At the same time, the high-temperature probe and the low-temperature probe can be used to compensate each other for monitoring, so that the monitored data can be more complete and the combustion status can be effectively understood.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] See also Figure 1 A multi-probe mutual compensation furnace temperature measuring device includes a water-cooled wall 1, a sealing box 2 is fixedly connected to the outside of the water-cooled wall 1, a probe sleeve 3 is fixedly connected to the inside of the sealing box 2, a probe adjustment fixture 6 is installed at the right end of the probe sleeve 3, a high-temperature probe 4 is fixedly installed inside the left end of the probe adjustment fixture 6, and a low-temperature probe 5 is fixedly connected to the left end of the probe adjustment fixture 6.

[0016] See also Figure 1 The sealing box 2 is made of aluminum alloy material, which has good corrosion resistance. The high-temperature probe 4 is in sliding contact with the probe sleeve 3, and the temperature measuring range of the high-temperature probe 4 is 400-1600°C. The low-temperature probe 5 is in sliding contact with the probe sleeve 3, and the temperature measuring range of the low-temperature probe 5 is 0-400°C.

[0017] See also Figure 1A defocusing motor 7 is installed on the lower outer side of the probe adjustment fixture 6 by bolts. The defocusing 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. A signal transmitter is arranged inside the instrument box 8 to transmit data signals. The probe sleeve 3 is in contact with the water-cooled wall 1, and the temperature can be transmitted through the probe sleeve 3.

[0018] The specific implementation process of the present invention is as follows: when monitoring the temperature inside the furnace, the temperature inside the furnace diffuses to the inside of the sealing box 2 through the waist hole. During the temperature radiation process, the temperature below 400°C can be monitored by the low-temperature probe 5, and the temperature above 400°C can be monitored by the high-temperature probe 4. The furnace stability can be monitored by dual probes at the same time, and the temperature can be monitored by the high-temperature probe 4 and the low-temperature probe 5 in a way that compensates each other, thereby effectively ensuring the integrity of the temperature data inside the furnace.
