Problems solved by technology

[0006] (3) In order to improve the strength of the thermocouple casing, the thickness of the casing tube wall can be increased, but with the increase of the tube wall thickness, the measurement accuracy of the thermocouple decreases due to the influence of the heat transfer effect of the material
This structure has limitations in industrial applications and can only be used in environments where there is no large stress, such as temperature detection for gas working fluids and liquid working fluids, but not for environments with solid extrusion and impact middle
When there is a large extrusion or impact, the drive assembly may not work, and the elastic retainer may be damaged due to extrusion

Embodiment 1

[0068] use Figure 1-5 The fixed bed reactor shown, the reactor packing and catalyst packing and the thermowell installation operation are carried out, and the steps are as follows:

[0069] 1. Use the casing centering device to align and fix the outer casing of the lower section of the reactor.

[0070] 2. Fill the filler and catalyst in place as required. After filling, the central positioning device can be removed by means of the hoisting hole of the positioning device.

[0071] 3. Install the gasket of the equipment flange in place, hoist the upper head assembly in place, align it according to the required orientation, and fasten the equipment flange studs. When tightening the equipment flange studs, be sure to Pay attention to the uniform force to ensure the sealing of the equipment flange.

[0072] 4. Insert the inner sleeve into the outer sleeve from the thermocouple insertion port at the upper end of the reactor, and fasten the nut between the inner sleeve and the up...

Embodiment 2

[0076] Without using the centering device for positioning, although the outer sleeve is not deformed, the outer sleeve cannot be adjusted.

Abstract

The invention relates to a fixed bed reactor which comprises an outer cylinder, a jacket positioned outside the outer cylinder, an upper seal head positioned above the outer cylinder, a lower seal head positioned below the outer cylinder, a pouring layer arranged around the inner wall of the outer cylinder, and a reaction space positioned in the pouring layer, the outer sleeve is inserted into the reaction space from the thermocouple insertion port of the upper sealing head, the inner sleeve is positioned in the outer sleeve, the thermocouple is inserted into the inner sleeve, the process gas inlet and the process gas outlet are communicated with the reaction space, and the filler discharge port is positioned below the reaction space and is communicated with the reaction space. According to the fixed bed reactor, the outer sleeve is not prone to deformation, and temperature measurement of the thermocouple is free of deviation.

Description

technical field [0001] The present invention relates to a fixed bed reactor. Background technique [0002] In the chemical production process, the measurement of temperature is very important. In order to accurately obtain the temperature information of the measuring point, the thermocouple probe is usually selected in the middle of the material as much as possible in engineering, so the thermocouple needs to go deep into the equipment under test and the inside of the pipeline in use. A protective sleeve needs to be installed on the thermocouple. [0003] Because the measured medium may cause corrosion, wear, extrusion, etc. to the thermocouple probe, which will cause damage to the thermocouple components and affect the accuracy of temperature measurement, in order to ensure accurate temperature measurement and ensure production safety, it is necessary to set thermocouple protection. casing. When temperature measurement is performed in the packing layer of the fixed bed r...
