Description

Technical Field

[0001] The utility model relates to the technical field of a reaction kettle exhaust device, and more specifically, to a fine-tuning device for a reaction kettle exhaust. Background Art

[0002] In a supercritical reaction kettle, the exhaust device is a crucial component, and its main function is to control the pressure and temperature inside the kettle. The exhaust device can keep the pressure and temperature inside the kettle within a stable range to ensure the accuracy and reliability of the reaction. Therefore, in the design and operation of a supercritical reaction kettle, the exhaust device is a very critical part. The existing exhaust devices have the disadvantages of being unable to quickly fine-tune and having inflexible maneuverability when adjusting the exhaust, so the structure needs to be upgraded. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fine-tuning device for a reaction kettle exhaust in order to solve the above technical problems.

[0004] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0005] A fine-tuning device for a reaction kettle exhaust includes a reaction kettle, and a first exhaust pipe, a second exhaust pipe, and a third exhaust pipe are arranged on both sides of the reaction kettle;

[0006] The number of the first exhaust pipes on each side is 2 and they are distributed on the front side and the rear side of the reaction kettle, the number of the second exhaust pipes on each side is 1, and the number of the third exhaust pipes on each side is 1;

[0007] One end of the first exhaust pipe is connected to the reaction kettle and the other end is connected to the second exhaust pipe;

[0008] An electric ball valve and a manual ball valve are sequentially arranged on the first exhaust pipe, and the electric ball valve is arranged on the side close to the reaction kettle.

[0009] The manual ball valve includes a valve body and a valve core. The valve body is provided with a first valve passage, a second valve passage, and a third valve passage. The first valve passage and the second valve passage are connected to the first exhaust pipe, and the third valve passage is connected to the third exhaust pipe. The valve core is provided with a first through groove, a second through groove, and a third through groove, and the first through groove, the second through groove, and the third through groove are communicated with each other. The manual ball valve further includes a handwheel and a valve rod. One end of the valve rod enters the valve body and is connected to the valve core, and the other end is connected to the handwheel. By rotating the handwheel, the valve core is driven to rotate, thereby finely adjusting the exhaust.

[0010] When the third through groove is directly opposite and communicated with the third valve passage, it is the initial state. In the initial state: the lower edge of the first through groove is aligned with the lower edge of the first valve passage, and the upper edge of the second through groove is aligned with the upper edge of the second valve passage;

[0011] In the initial state, the valve core rotates counterclockwise, and the rotation angle of the valve core is A;

[0012] When A < 30°, the ports of the first valve passage and the second valve passage remain fully open, and the port of the third valve passage becomes smaller and smaller;

[0013] When A is 30°, the ports of the first valve passage and the second valve passage remain fully open, the third valve passage is closed, and the right edge of the third through groove is aligned with the left edge of the third valve passage, the upper edge of the first through groove is aligned with the upper edge of the first valve passage, and the lower edge of the second through groove is aligned with the lower edge of the second valve passage;

[0014] When 30° < A < 60°, at this time, the ports of the first valve passage and the second valve passage become smaller and smaller, and the third valve passage remains closed;

[0015] When A is 60°, the ports of the first valve passage, the second valve passage, and the third valve passage are all closed.

[0016] The outer walls of the reaction kettle, the second exhaust pipe, and the third exhaust pipe are all coated with a sound insulation layer.

[0017] The sound insulation layer sequentially includes a butyl damping rubber layer, fiberglass sound insulation cotton, and a tin foil layer from the inside to the outside; the fiberglass sound insulation cotton is bonded to the butyl damping rubber layer, and the tin foil layer is bonded to the fiberglass sound insulation cotton. The butyl damping rubber layer is respectively bonded to the reaction kettle, the second exhaust pipe, and the third exhaust pipe. The bonding glue used between the sound insulation layers can be silicone rubber glue or epoxy resin glue, and it can work stably at a temperature of about 200 degrees Celsius. The combination of the butyl damping rubber layer and the fiberglass sound insulation cotton has a better sound insulation effect. The butyl damping rubber layer has good flame retardant, shock absorption, and noise reduction performance, and the fiberglass sound insulation cotton has good flame retardant and sound absorption performance. The tin foil layer has very excellent reflection performance, and it can reflect the sound wave in the opposite direction, thereby reducing the penetration of noise and effectively enhancing the sound insulation effect.

[0018] One end of the second exhaust pipe and the third exhaust pipe are both connected to the waste gas treatment device, and the gas in the kettle body is discharged into the waste gas treatment device through the second exhaust pipe and the third exhaust pipe for centralized treatment.

[0019] Working principle: The electric ball valve can automatically execute with high efficiency when executing the set parameters. However, when fine-tuning the exhaust, since it is troublesome to modify the exhaust parameters on the controller of the electric ball valve and cannot meet the requirement of quickly controlling the exhaust, the cooperation with the manual ball valve can make up for the above deficiencies.

[0020] An electric ball valve and a manual ball valve are respectively arranged on the first exhaust pipe to achieve fine control of the exhaust gas. The electric ball valve senses the changes in the exhaust gas parameters through the actuator, thereby automatically adjusting the valve opening; while the manual ball valve can be fine-tuned by the handwheel to meet the exhaust speed requirements.

[0021] The beneficial effects of the utility model are as follows:

[0022] An electric ball valve and a manual ball valve are respectively arranged on the first exhaust pipe to achieve quick fine-tuning of the exhaust gas, and flexible operation; the outer walls of the reactor, the second exhaust pipe and the third exhaust pipe are all covered with a sound insulation layer, and the sound insulation layer is arranged to avoid noise pollution during exhaust.

[0035] An electric ball valve 5 and a manual ball valve 6 are sequentially arranged on the first exhaust pipe 2, and the electric ball valve 5 is arranged on the side close to the reaction kettle 1.

[0036] The manual ball valve 6 includes a valve body 7 and a valve core 8. The valve body 7 is provided with a first valve passage 9, a second valve passage 10, and a third valve passage 11. The first valve passage 9 and the second valve passage 10 are connected to the first exhaust pipe 2, and the third valve passage 11 is connected to the third exhaust pipe 4. The valve core 8 is provided with a first through groove 12, a second through groove 13, and a third through groove 14, and the first through groove 12, the second through groove 13, and the third through groove 14 communicate with each other. The manual ball valve 6 further includes a handwheel 15 and a valve rod 16. One end of the valve rod 16 enters the valve body 7 and is connected to the valve core 8, and the other end is connected to the handwheel 15. By rotating the handwheel 15, the valve core 8 is driven to rotate, thereby finely adjusting the exhaust.

[0037] When the third through groove 14 is directly opposite and communicated with the third valve passage 11, it is the initial state. In the initial state: the lower edge of the first through groove 12 is aligned with the lower edge of the first valve passage 9, and the upper edge of the second through groove 13 is aligned with the upper edge of the second valve passage 10;

[0038] In the initial state, the valve core 8 rotates counterclockwise, and the rotation angle of the valve core 8 is A;

[0039] When A < 30°, the openings of the first valve passage 9 and the second valve passage 10 remain completely open, and the opening of the third valve passage 11 becomes smaller and smaller;

[0040] When A is 30°, the openings of the first valve passage 9 and the second valve passage 10 are kept fully open, the third valve passage 11 is closed, and the right edge of the third through groove 14 is aligned with the left edge of the third valve passage 11, the upper edge of the first through groove 12 is aligned with the upper edge of the first valve passage 9, and the lower edge of the second through groove 13 is aligned with the lower edge of the second valve passage 10;
