Description of the Related Art Inside a riser (upflow reaction tube) of a fluid catalytic cracking unit in the petroleum refining industry, a three-phase fluid of steam as a gas, an oil vapor, a catalyst as a solid, and a raw oil as a liquid is 15 m / sec to 30 m / sec. It flows at a high speed. Conventionally, the decomposition reaction has been controlled by a thermometer installed in a disengager (separation tower, conventionally called a reaction tower) installed at the end of the riser. Here, the internal flow rate is as low as about lm / sec in order to separate the catalyst and the reaction product. However, the catalyst of the fluid catalytic cracking apparatus has been rapidly improved in recent years, and the required reaction time has been reduced from 0.1 seconds to 2 seconds. This means that the reaction is completed at the riser portion and that it is necessary to control the reaction. In order to monitor and control the reaction of the riser section, it is necessary to install a temperature measuring device inside the riser and directly measure the temperature of the internal three-phase fluid. However, a fluid flows at a high speed under the above-mentioned conditions, and a three-phase fluid has the following two problems, and such a temperature measuring device cannot be installed.

磨耗試験を実施したが1年も寿命はなかった例がある。One of the problems is that a Karman vortex is likely to be formed around a thermometer in a normal fluid, which may cause resonance and breakage of the thermometer. Therefore, a design is made to calculate the Karman vortex generation conditions and prevent the thermometer from resonating. However, the calculation of the Karman vortex generation conditions has at most experience and knowledge up to a two-phase fluid, and it is difficult at present to design a three-phase fluid to accurately prevent resonance of a thermometer. Alternatively, to prevent this, a thermometer that is much thicker than a normal thermometer is required, and disadvantages in other aspects such as accuracy of the thermometer and fluid resistance arise. The second problem is that the catalyst flowing at a high speed has a high hardness and is close to an abrasive, so that a normal metal (such as stainless steel) is worn and damaged within one year. The inventors of the present invention have actually conducted a wear test by hardening stainless steel on the surface of a thermometer, but there is an example in which the life of the thermometer was not one year.

Also, as a countermeasure against Karman vortex at the time of measuring the temperature in a fluid, a protective tube having a specific cross-sectional shape is provided (Japanese Patent Laid-Open No. 10-06226).

Further, Japanese Patent Application Laid-Open No. Hei 10-221178 discloses that the gap between the thermowell and the thermometer is filled with an electrothermal accelerating substance, or the temperature sensing part of the thermometer is brought into close contact with the tip of the thermowell to quickly and accurately measure the temperature. To improve. However, delays and errors in temperature measurement due to the presence of the protection tube have not been completely eliminated. In particular, in order to prevent Karman vortices and ensure sufficient wear resistance, the protective tube must be large and thick, and the above-mentioned disadvantages have become significant.

The protective tube of the present invention may be a tubular one having an open end. The structure is such that a thermometer is inserted inside the protective tube (see FIG. 1). Thermometers are usually
A thermocouple thermometer or a resistance thermometer is used, but any mercury thermometer, alcohol thermometer, or any other contact-type thermometer having a temperature measuring section at its tip may be used. If it demonstrates according to FIG. 1 as a typical example, the thermometer 1 will become the structure inserted into the inside of the protective tube 2 which the front-end | tip part opens to the fluid to be measured from the outside of the fluid to be measured. I have. It is preferable that the thermometer 1 has a temperature measuring portion at a tip portion, and the tip portion is located substantially at the same position as the opening 3 of the protective tube 2. If it protrudes from the protective tube, that part is susceptible to abrasion.If it is too dent, accurate temperature measurement cannot be performed, or the catalyst is caught in the dent part of solids or liquids, and this part wears out Sometimes. Further, the gap between the protective tube 2 and the thermometer 1 is preferably as small as possible within a range where the thermometer 1 can be inserted and removed. If it is too wide, foreign matter (catalyst, tar content, etc.) will be clogged, the thermometer will vibrate, and the temperature measurement will be inaccurate.

好適に実施できる。The fluid to be measured according to the present invention may not be exactly called a fluid in addition to a normal fluid (single-phase flow, multi-phase flow), but a boiling bed, a fluidized bed, or powder or particles vibrates. May be available. Usually, a multi-phase fluid, particularly a multi-phase fluid containing a solid, is suitable as the fluid to be measured to exhibit the effects of the present invention. Among them, the two-phase fluid of gas or liquid and solid or the three-phase fluid of gas, liquid and solid is most effective. In addition, it is suitable for high-speed fluid measurement because sufficient measures against Karman vortices can be taken. Examples of gas, liquid, and solid three-phase fluids include those used in catalytic cracking equipment in the petroleum refining industry. As described above, conventionally, it has been difficult to measure the temperature of the riser, which is the reaction part of the catalytic cracking device, but it can be suitably performed by the temperature measuring device of the present invention.

て多少の減肉に耐えうるようにすることが好ましい。The outside of the protective tube of the temperature measuring device of the present invention is preferably made of a wear-resistant material. When the fluid to be measured of the present invention is a multi-phase fluid, and among them, a two-phase fluid of gas or liquid and a solid or a three-phase fluid of gas, liquid, and solid, the effect of abrasion due to solid particles is large, and a protective tube is usually used. When made of the above material, the life is shortened. In such a case, it is preferable that the outside of the protective tube is made of a wear-resistant material.
Examples of the wear-resistant material include alumina, silica, silica-alumina, refractory materials, castables, and the like. Particularly, in an atmosphere where heat resistance is required, a refractory material, castable, or the like is preferable. It is preferable that the outside of the protection tube is made of a wear-resistant material, but in consideration of the structural strength of the protection tube, it is preferable that the inside of the protection tube is made of a metal material (such as stainless steel) and the outside is lined with castables or the like.
In this case, the outer surface of the inner metal material may have irregularities,
Installation of a lining such as an outer castable can be facilitated by installing a projection or the like, and it can be made difficult to peel off (see FIG. 2). When measuring a fluid that easily wears a thermometer, etc., increase the wall thickness of the portion of the thermometer tip that is in direct contact with the fluid (usually the tip of the sheath tube of the thermometer) and withstand some thinning. Preferably.

の挿入、取り出しが容易になる。The gap between the protective tube and the thermometer is preferably narrow. However, if the gap is too small, it becomes difficult to insert and remove the thermometer. It may stick. Therefore, by filling the space between the thermometer and the protective tube with a filler without making the gap too narrow, it is possible to prevent foreign substances from entering the gap and vibration of the thermometer (see FIG. 3). As the filler, those which are somewhat resilient when filled, such as glass fiber, asbestos, ceramic paper, cloth, paper, fiber, and film, are usually used. However, depending on the temperature of the measurement atmosphere or the like, it is necessary to use one that is compatible with the atmosphere. If an appropriate filler is selected, it becomes easy to insert and remove the thermometer from the protective tube.

ン渦に対する耐性が特によい条件と考えられる。In the petroleum refining industry, high-temperature, high-pressure fluids are often handled, and there are also many gas-liquid mixed fluids, gas-solid mixed fluids, and gas-liquid-solid mixed fluids. For this reason, in the method of manufacturing a petroleum product by a petroleum refining device, the temperature of a fluid to be measured such as a gas-liquid mixed fluid, a gas-solid mixed fluid, a gas-liquid-solid mixed fluid is measured using the temperature measuring device of the present invention, A petroleum product can be manufactured efficiently while controlling the operating conditions of the petroleum refinery. In particular, as described above, the temperature measurement device of the present invention is very suitably used for the temperature measurement of the riser section of the catalytic cracking device, particularly the residual oil catalytic cracking device as described above, and the control of the cracking rate, heat balance, etc. is easy. Become. In this case, the protection tube of the temperature measuring device in the riser portion of the catalytic cracking device is relatively thick and has a length of about 120 mm, which is considered to be a condition particularly excellent in resistance to Karman vortex.

[Example 1] Actually, the temperature measuring device of the present invention was applied to a riser section of a fluid catalytic cracking device (FCC) to give a correct temperature indication value and perform accurate reaction control while maintaining a life of 4 years or more.

グとする。In the FCC, the function of the riser has been changed from a transfer tube to a reaction tube due to the recent improvement in catalytic activity. Gas-liquid-solid three-phase fluid flows in the riser at high speed, preventing resonance due to Karman vortex and having a life of one year or more due to wear of the catalyst. Directly and accurately measuring fluid temperature No thermometer was available. Then, the temperature measuring device of the present invention was applied. The thermometer protection tube was protruded into the riser, and the protruding length was 120 mm from the inner wall surface. This length is usually preferably at least 25 mm, particularly preferably at least 100 mm. This is because the length is not affected by the temperature drop or the like due to the backflow of the catalyst on the riser wall surface. The outer shape of the protection tube for preventing abrasion by the catalyst is designed so that it does not fall into the resonance range by calculating the Karman vortex generation condition from the fluid condition and the like (because it cannot be accurately made, it is preferable to have a shape that takes into account the safety factor). . Since the thermometer is not exposed to the fluid except for the opening at the tip, the thermometer has a structure that receives almost no stress from the Karman vortex of the fluid. The material inside the protection tube is stainless steel and has a heat resistance of 550 ° C. or more. The outside of the protection tube shall be a wear-resistant castable lining reinforced with anchors.

に制御し、効率的な運転を達成することが出来た。As the thermometer, a thermocouple sealed in a stainless steel sheath tube was used. The ceramic paper was used as a filler between the thermometer and the protective tube by winding the ceramic paper around the thermometer and inserting it into the protective tube. The protruding length of the thermometer into the riser is almost the same as the protruding length of the protective tube (120 mm from the inner wall surface). It is preferable that only the surface perpendicular to the axis of the thermometer tip, which is the temperature measuring section, is exposed to the fluid at the opening at the tip of the protective tube. At the tip of the thermometer, the material used for the sheath tube was set to a thickness of about 3 mm with a margin for corrosion allowance of about 3 mm in order to cope with a decrease in wall thickness due to wear. When the FCC in which the temperature measuring device was installed inside the riser was operated for four years, the temperature measuring device had a sufficient life. In the operation of the FCC, the measurement of the reaction temperature in the riser section was performed accurately and quickly, and the target factors such as the decomposition rate were accurately controlled, so that the efficient operation was achieved.
