For the sulfur recovery equipment, its outer wall includes a heat preservation layer 1, a furnace brick 2, and a thermocouple installation channel 3 penetrating through the heat preservation layer and the furnace brick. Since the installation and / or replacement of thermocouples is carried out without stopping the operation of the equipment, the furnace material (such as 1200 degree Celsius high temperature gas) is easy to contact with the air outside the furnace through the thermocouple installation channel, causing pollution of the furnace material and / or risk of equipment operation.

[0033] A valve control module 4 is arranged at the entrance of the thermocouple installation channel outside the equipment, the channel through the valve control module is flush with the thermocouple installation channel, a valve 4-1 and a first reverse blowing port 4-2 are arranged on the valve control module, the valve controls the opening and closing degree of the channel through the valve control module, the first reverse blowing port communicates with the channel through the valve control module, and according to the process requirement, inert protective gas (such as nitrogen, helium or argon), air or mixed gas is blown into the channel through the first reverse blowing port.

Preferably, along the direction of thermocouple installation, the first reverse blowing port is arranged near the entrance of the thermocouple installation channel compared with the valve.

[0034] One side of the valve control module 4 is arranged at the entrance of the thermocouple installation channel, and the other side is connected with the sealing connection sleeve 8 through the installation flange 5. The first vertical fixing part 6-2 of the guide part 6 is arranged between the installation flanges 5 and is fixed by bolts and nuts.

At this time, the thermocouple is suspended as a whole, relying on the cooperation of the guide component 6, the track component 6-1 and the movement module 7, so that the thermocouple body advances or retreats in the overall thermocouple installation channel, that is, it extends into the device interior or is taken out from the device interior, as Figure 6 As shown, the case is just to extend the thermocouple (temperature measuring end 9-4) into the device interior through the overall thermocouple installation channel, and to perform temperature measurement and monitoring.

[0037] As shown, the structure diagram of the thermocouple used is shown. The thermocouple includes a junction box, a connecting component, a limiting flange, and a temperature measuring end.

According to the process requirement, the second reverse blowing port is used to blow inert protective gas (such as nitrogen, helium or argon), air or mixed gas into the channel, and is used in cooperation with the valve of the valve control module 4 and the first reverse blowing port.

During this process, the installation speed of the thermocouple is controlled by manual control or PLC program control, so as to avoid the adverse effects caused by temperature mutation. When the temperature measuring end of the thermocouple enters the equipment and is located at the preset position, the gas sent through the first reverse blowing port and / or the second reverse blowing port is paused, and the compression pad and the packing in the sealing connecting sleeve are compacted by using the compression lock nut, so that sealing is realized while locking.

[0041] When the thermocouple needs to be replaced, the first reverse blowing port, the second reverse blowing port or the combination thereof is selected to send gas to the installation channel and / or the equipment according to the actual working condition, so as to avoid the escape of heat and / or material, the compression lock nut is loosened, the thermocouple is separated from the installation channel by manual control or PLC program control, and the valve is closed according to the actual situation.
