Abstract
Description
Technical Field
[0001] This utility model relates to the chemical industry, and in particular to a sampler for a reaction vessel. Background Technology
[0002] In esterification reactions, particularly the production of isononyl isononanoate, a standard procedure involves sampling from a large reactor for testing. Current reactors are generally over two meters long, making sampling from the bottom valves both unsafe and inconvenient. Using simple samplers, such as pipettes, results in an inlet diameter that is too small to prevent backflow, leading to excessively long sampling times. Conversely, enlarging the inlet diameter of a pipette-type sampler makes it very easy for the sampled liquid to flow back into the reactor. Furthermore, since the viscosity of the esterification reaction solution is greater than that of water, a small inlet diameter further prolongs the sampling time.
[0003] Therefore, it is particularly important to propose a reactor sampler that can achieve rapid sampling from above the reactor while maintaining a simple structure. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes a reactor sampler and a reactor, which can achieve rapid sampling from above the reactor with a simple structure.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] This utility model provides a reactor sampler, comprising a reactor body, a reactor cover disposed on the reactor body, a sampling port disposed on the reactor cover, and a sampling tube extending from the outside of the reactor body into the reactor body through the sampling port; the outer diameter of the sampling tube is less than or equal to the inner diameter of the sampling port; the lower end of the sampling tube is a circular inlet / outlet with a reduced diameter structure; the sampling tube also includes a plug and a check ball; the plug is disposed at the upper end of the sampling tube; the check ball is disposed inside the sampling tube, the diameter of the check ball is greater than the diameter of the circular inlet / outlet and smaller than the diameter of the sampling tube, and less than 50% of the volume of the check ball is exposed outside the sampling tube through the circular inlet / outlet.
[0007] It should be noted that the outer diameter of the sampling tube is less than or equal to the inner diameter of the sampling port, and the sampling tube can extend into the interior of the reaction vessel through the sampling port.
[0008] The reactor sampler according to the embodiments of this utility model has at least the following beneficial effects: the tube plug prevents the liquid in the reactor from entering the sampler prematurely before reaching the sampling height. After reaching the sampling height, the tube plug is removed, and sampling can then be performed. By setting a check ball in the sampling tube, the problem of liquid backflow caused by excessively large inlet and outlet of the sampling tube can be effectively prevented. Moreover, with the check ball exposed, in the actual sampling process, the check ball can be supported by the end of the sampling tube resting against the bottom or inner wall of the reactor body, thereby increasing the liquid sampling speed and solving the problem of slow liquid sampling speed. If the check ball is not exposed, unlike sampling in water, the viscosity of the esterification reaction liquid in the reactor body is too high, and the gravity of the check ball itself will greatly slow down the sampling speed of the high-viscosity esterification reaction liquid. This problem is particularly obvious when the sampling liquid level is shallow.
[0009] It should be noted that the tube plug is matched with the upper port diameter of the sampling tube.
[0010] According to some embodiments of this utility model, the diameter of the circular inlet and outlet is 0.5-5.0 cm.
[0011] According to some embodiments of this utility model, the reactor lid is circular.
[0012] According to some embodiments of this utility model, the shape of the check ball is a sphere.
[0013] According to some embodiments of this utility model, less than 50% and more than 20% of the volume of the check ball is exposed outside the sampling tube through the circular inlet and outlet.
[0014] According to some embodiments of the present invention, the reactor sampler further includes a rotating shaft disposed on the reactor body and perpendicularly connected to the center of the reactor cover; the reactor cover and the sampling port are rotatable around the rotating shaft.
[0015] According to some embodiments of this utility model, the reactor sampler further includes a plurality of horizontal plates disposed at different heights on the inner wall of the reactor body; the horizontal plates are directly below the rotation trajectory of the sampling port. By rotating the reactor lid, the horizontal plates at different heights can be selected, allowing the reactor to be positioned at different heights. Furthermore, the arrangement of the horizontal plates is more conducive to supporting the check ball.
[0016] According to some embodiments of this utility model, the horizontal strip is arranged in a stepped manner.
[0017] According to some embodiments of this utility model, the number of horizontal strips is 2-10; preferably, the number of horizontal strips is 2-5.
[0018] According to some embodiments of the present invention, the reactor sampler further includes an annular sealing plate disposed on the sampling port, wherein the inner diameter of the annular sealing plate is adapted to the outer diameter of the sampling tube, and the outer diameter of the annular sealing plate is larger than the diameter of the sampling port.
[0019] According to some embodiments of this utility model, the reactor sampler further includes a buffer cavity disposed between the reactor lid and the reactor body. The buffer cavity also has a connection port, and the bottom of the buffer cavity is connected to the reactor body through a connection port corresponding to the horizontal plate in the vertical direction. The connection port has two states: open and closed, and the diameter of the connection port is larger than the diameter of the sampling tube. By adding a buffer cavity, in addition to preventing liquid splashing, this reactor sampler, together with the annular sealing plate, can achieve negative pressure sampling operation.
[0020] According to some embodiments of this utility model, the connection port is circular.
[0021] The beneficial effects of this utility model are:
[0022] This invention proposes a reactor sampler. By incorporating a check ball within the sampling tube, it effectively prevents liquid backflow caused by excessively large inlet and outlet sizes. Furthermore, the exposed check ball allows for support during sampling by simply resting the end of the sampling tube against the bottom or inner wall of the reactor body, thus increasing the sampling speed and addressing the issue of slow sampling rates. The addition of a buffer cavity not only prevents liquid splashing but also enables negative pressure sampling when used in conjunction with the annular sealing plate. Attached Figure Description
