AI Technical Summary
Existing technologies are insufficient to meet the sealing and connection requirements of open glass-lined reactors under high pressure conditions, resulting in instability of the reactors under high pressure.
Thickened first high-diameter flanges are installed at the tank body and tank cover to increase the number of effective locking threads when bolts are tightened. An arc transition section is provided on the inner wall of the flange, which, together with the countersink and sealing gasket, achieves the fastening and sealing effect between the tank body and the tank cover.
This improves the locking strength and sealing performance of the reactor under high pressure, ensuring a stable connection between the tank body and the lid, and meeting the requirements of high-pressure reactions.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass-lined reactor application technology, and specifically relates to an open-type high-pressure glass-lined reactor. Background Technology
[0002] The internal pressure of glass-lined reactors is mostly below 1 MPa, with most below 0.6 MPa. Reactors with pressures above 0.6-1 MPa are considered high-pressure reactors, and some can reach several megapascals. Depending on the application requirements, the manufacturing processes of high-pressure reactors differ from those of conventional reactors. Conventional reactors have thinner walls, with a structure primarily designed to meet low-pressure requirements, and adhere to the standard GB / T25027-2010. They are less expensive and have a shorter manufacturing cycle. High-pressure reactors, on the other hand, must comply with GB150-2011 "Pressure Vessels" or ASME and other high-pressure vessel standards, significantly increasing costs (materials, sealing technology, testing fees, and regular maintenance).
[0003] The existing technologies, such as the glass-lined reactor head announced in CN209968385U and the high-strength corrosion-resistant glass-lined reactor announced in CN206372825U, are all technical solutions for conventional reactors. Such reactors are closed reactors, while the invention is an open high-pressure reactor, which requires the tank cover and tank body to be fastened together by bolts. Therefore, under the requirements of high pressure, the tank body and tank cover need to be able to seal and connect sufficiently firmly.
[0004] Based on the aforementioned existing technologies and problems, the inventors provide an open reactor solution suitable for high pressure. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an open-type high-pressure glass-lined reactor. The application of the first high-diameter flange at the tank body and tank cover can improve the tightness and make the reactor meet the requirements for use as a high-pressure reactor.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] An open-type high-pressure glass-lined reactor includes a tank body and a tank cover. A first high-diameter flange is provided at the end face of the tank body and the tank cover. The first high-diameter flange has a countersunk groove and bolt holes for bolt tightening. An arc-shaped transition section is provided on the inner wall of the first high-diameter flange. The thickness of the first high-diameter flange is 3.5-5 times the wall thickness of the tank cover. By thickening the first high-diameter flange, the effective number of locking threads for bolt tightening is increased, improving the tightening strength and meeting the high-pressure reaction requirements of the tank. The tank cover has a stirring port, and a second high-diameter flange is provided on the stirring port. The tank cover also has a pipe opening and a sight glass manhole, and a second high-diameter flange is provided on the pipe opening and the sight glass manhole. The bottom of the tank body has a discharge port, and a second high-diameter flange is provided at the discharge port.
[0008] A sealing gasket is provided in the groove between the first high-diameter flanges to achieve a sealing effect when the tank body and tank cover are fastened together.
[0009] The tank body is equipped with a jacket on the outside, and the jacket is equipped with a steam inlet and a liquid outlet; the bottom of the jacket is equipped with a liquid inlet and a condensate outlet.
[0010] The top of the jacket is also provided with a vent.
[0011] The bottom of the jacket is also provided with a drain port.
[0012] The tank is equipped with support legs and a fixing frame that can be used with bolts and mounting brackets to install and fix the reactor.
[0013] It should be emphasized that a groove is also provided on the end face of the second high-diameter flange.
[0014] The advantages of this utility model compared with the prior art are as follows:
[0015] In this design, a first high-diameter flange is provided at the tank cover and the tank body port. The thickness of the first high-diameter flange is 3.5-5 times the thickness of the tank cover wall. By thickening the first high-diameter flange, the effective number of locking threads when the bolts are tightened is increased, thereby improving the tightening strength and meeting the high-pressure reaction requirements of the tank. Furthermore, an arc transition section is provided on the inner wall of the first high-diameter flange to achieve a smooth transition. With the use of a settling tank, this avoids the drawback of conventional right-angle settings causing the tank body and tank cover end faces to squeeze against each other and damage the glaze layer during tightening. At the same time, the end face of the bolt through hole of the first high-diameter flange does not need to be glazed, thereby enabling strong bolt tightening and meeting the application requirements of the reactor under high-pressure environment.
