Abstract
The technical solution of the utility model relates to a kind of upper cover hermetically-sealed construction for reactor, and comprise upper cover, reactor, thermocouple sheath, nut and pipe nipple, is characterized in that; Described upper cover central point is provided with the center hole passed for thermocouple sheath, and described pipe nipple one end is tightly fixed in described upper cover center hole, and the other end of pipe nipple is threaded nut; Described nut is connected with upper cover by pipe nipple; Described thermocouple sheath and be provided with cutting ferrule between nut and pipe nipple and seal; Described thermocouple sheath extends to inside reactor through nut, pipe nipple, upper cover successively.Coordinated by thermocouple sheath pipe nipple and nut to use, facilitate the dismounting of temperature measuring equipment on the one hand, also solve the sealing problem of upper cover center hole on the other hand, effectively prevent reacting gas from leaking from upper cover; Simultaneously can the bed temperature of detection reaction in real time, and can the hot(test)-spot temperature of easy-to-look-up reaction, and then determine the hotspot location of reaction.
Description
Technical field
The utility model relates to a kind of upper cover technology for catalyst test and appraisal reactor, particularly a kind of upper cover hermetically-sealed construction for reactor.
Background technology
In Catalyst Design exploitation and processing process, the Main Means that the performance for catalyst carries out testing and assessing carries out chemical reaction, exactly according to the properties obtaining quality evaluation of the experimental data catalyst in reactor.For the ease of the hot(test)-spot temperature of detection reaction and the bed temperature of hotspot location and measurement reaction, a circular hole is provided with, so that thermocouple extends to inside reactor with the thermowell being wrapped in its appearance through circular hole carry out temperature detection in the upper cover center of catalyst test and appraisal reactor.
But so just bring the problem of equipment sealing.Upper cover adopts screw thread to be connected with reactor, and centre is provided with sealing ring, can ensure can not leak in course of reaction, and the aperture of centre cannot use sealing gasket.How not only can facilitate detection reaction temperature but also can ensure that the sealing problem of reactor is the difficulties needing to solve.
Utility model content
Be directed to the problems referred to above, the applicant is through repetition test, design and develop the hermetically-sealed construction for reactor upper cover, both thermocouple can have been allowed to pass upper cover center hole with the thermocouple sheath being wrapped in its appearance, the detection of temperature can be carried out at any time, in turn ensure that reacting gas can not leak from upper cover, facilitate the dismounting of temperature measuring equipment simultaneously.
Concrete technical scheme of the present utility model is as follows:
For the upper cover hermetically-sealed construction of reactor, comprise upper cover, reactor, thermocouple sheath, nut and pipe nipple, is characterized in that; Described upper cover central point is provided with the center hole passed for thermocouple sheath, and described pipe nipple one end is tightly fixed in described upper cover center hole, and the other end of pipe nipple is threaded nut; Described nut is connected with upper cover by pipe nipple; Described thermocouple sheath and be provided with cutting ferrule between nut and pipe nipple and seal; Described thermocouple sheath extends to inside reactor through nut, pipe nipple, upper cover successively.
Further, described upper cover is threaded with reactor, is provided with asbestos pad sealing ring between upper cover and reactor.
Further, described pipe nipple is one start screw pipe nipple.
Further, described nut center offers the circular hole that internal diameter is 3.5mm.
The beneficial effects of the utility model are:
1, by the use of pipe nipple and nut, facilitate the dismounting of temperature measuring equipment on the one hand, also solve the sealing problem of upper cover center hole on the other hand, effectively prevent reacting gas from leaking from upper cover center hole;
2, thermocouple be wrapped in thermocouple sheath stretch into reactor can detection reaction temperature in real time, observe reaction bed temperature;
3, thermocouple and the thermocouple sheath that is wrapped in its appearance extend to the detection that inside reactor can carry out reaction temperature through upper cover center hole, in turn ensure that the sealing property of reactor simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the upper cover hermetically-sealed construction for reactor of the present utility model,
Accompanying drawing 2 is close-up schematic view of accompanying drawing 1,
Upper cover top view looked by accompanying drawing 3, in figure:
1. upper cover, 2. thermocouple sheath, 3. nut, 4. pipe nipple, 5. cutting ferrule, 6 reactors, 7. asbestos pad sealing ring, 8. center hole.
Detailed description of the invention
By reference to the accompanying drawings the upper cover hermetically-sealed construction of the utility model for reactor is illustrated further.
As shown in accompanying drawing 1,2 and 3, for the upper cover hermetically-sealed construction of reactor, comprise upper cover 1, reactor 6, thermocouple sheath 2, nut 3 and pipe nipple 4, is characterized in that; Described upper cover 1 center is provided with the center hole 8 passed for thermocouple sheath 2, and described pipe nipple 4 one end is tightly fixed in described upper cover 1 center hole 8, and the other end of pipe nipple 4 is threaded nut 3; Described nut 3 is connected with upper cover 1 by pipe nipple 4; Described thermocouple sheath 2 and be provided with cutting ferrule 5 between nut 3 and pipe nipple 4 and seal; It is inner that described thermocouple sheath 2 extends to reactor 6 through nut 3, pipe nipple 4 and upper cover 1 successively.
Further, described upper cover 1 is threaded with reactor 6, is provided with asbestos pad sealing ring 7 between upper cover 1 and reactor 6.
Further, described pipe nipple 4 is one start screw pipe nipple.
Further, described nut 3 center offers the circular hole that internal diameter is 3.5mm.
Coordinated by thermocouple sheath pipe nipple and nut to use, facilitate the dismounting of temperature measuring equipment on the one hand, also solve the sealing problem of upper cover center hole on the other hand, effectively prevent reacting gas from leaking from upper cover center hole; Thermocouple and be wrapped in its appearance thermocouple sheath through upper cover center hole and extend to inside reactor can the bed temperature of detection reaction in real time, and the hot(test)-spot temperature of easy-to-look-up reaction, and then determine the hotspot location of reaction.
