Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel system. Background Technology

[0002] In industrial production, reaction vessels are usually equipped with exhaust pipes to discharge waste gas from the reaction vessel, in order to maintain the balance of the reaction system and avoid overpressure.

[0003] Before a reaction begins, the reactor is typically evacuated to remove air. However, after evacuation, air is drawn back into the reactor through the exhaust pipe to balance the pressure inside. This air drawn back from the outside atmosphere may contain particulate matter and contaminants, which can contaminate the product inside the reactor. Utility Model Content

[0004] The purpose of this invention is to provide a reaction vessel system that ensures pressure balance within the reaction vessel and prevents contamination of the products inside.

[0005] To achieve this objective, the present invention adopts the following technical solution:

The pipelines include a first branch pipeline, a second branch pipeline, and a third branch pipeline connected in parallel to the reaction vessel. The first branch pipeline can be connected or disconnected, and when connected, it introduces purified gas into the reaction vessel. The second branch pipeline can be connected or disconnected, and when connected, it is used to discharge gas from the reaction vessel. The third branch pipeline is connected to a vacuum pump, and when connected, it can evacuate the reaction vessel.

[0007] In some possible implementations, the first branch pipe is provided with a first control valve, which can connect or disconnect the first branch pipe; the second branch pipe is provided with a second control valve, which can connect or disconnect the second branch pipe; and the third branch pipe is provided with a third control valve, which can connect or disconnect the third branch pipe.

[0009] In some possible implementations, one end of the first branch pipe, the second branch pipe, and the third branch pipe are all connected to the main pipe, which is connected to the reactor.

[0010] In some possible implementations, the other end of the first branch pipe is connected to the outlet of the gas filter.

[0011] In some possible implementations, the gas filter includes a housing, a filter element, and a connector. The filter element is disposed within the accommodating space formed by the connector and the housing. The connector has an inlet and an outlet. The inlet communicates with the gap formed by the filter element and the housing. The outlet communicates with the internal space of the filter element and forms the outlet of the gas filter.

[0012] In some possible implementations, the filter element is a metal filter element, an activated carbon filter element, or a polytetrafluoroethylene filter element.

[0013] In some possible implementations, the housing and the connector are detachably connected, and the connector and the filter element are detachably connected.

[0014] In some possible implementations, the connector is plate-shaped with a threaded connecting pipe in the middle, the filter element has a threaded boss, the bottom of the filter element is supported inside the connector, and the outer shell covers the top of the filter element; the boss passes through the connecting pipe, and the external thread of the boss and the thread of the connecting pipe are threadedly connected, the connecting pipe forming the air outlet; the air inlet is provided between the edge of the connecting pipe and the connector.

[0015] In some possible implementations, there are multiple air inlets, and the multiple air inlets are evenly arranged around the air outlet.

[0016] The beneficial effects of this utility model are:

[0017] This invention provides a reaction vessel system. During vacuuming, the first and second branch pipes are first blocked, while the third branch pipe is connected. The vacuum pump is then turned on to extract the gas from the reaction vessel, thus creating a vacuum. Afterward, the first branch pipe is connected, while the second and third branch pipes are blocked, allowing purified air to enter the reaction vessel to balance the internal pressure. Before using the reaction vessel, a vacuum is created, and purified air is introduced to balance the pressure within the system and prevent contamination of the product. During use, the first and third branch pipes are blocked, while the second branch pipe is connected. Waste gas generated in the reaction vessel can be discharged through the second branch pipe at any time, ensuring internal pressure balance. The system is simple in structure and easy to operate.

[0028] like Figures 1-3 As shown, this embodiment provides a reaction vessel system, including a reaction vessel 1 and a pipeline 2 connected to the reaction vessel 1. The pipeline 2 includes a first branch pipeline 21, a second branch pipeline 22, and a third branch pipeline 23 connected in parallel to the reaction vessel 1. The first branch pipeline 21 can be connected or disconnected. When connected, purified gas is introduced into the reaction vessel 1. The second branch pipeline 22 can be connected or disconnected. When connected, it is used to discharge gas from the reaction vessel 1. The third branch pipeline 23 is connected to a vacuum pump 4. The third branch pipeline 23 can be connected or disconnected. When connected, it can evacuate the reaction vessel 1.

[0029] The reaction vessel 1 specifically includes a shell, a stirring device 103, and a motor 104 for driving the stirring device 103. The motor 104 drives the stirring device 103 to stir the reactants inside the shell. The shell is provided with a feed inlet 101, a discharge outlet 102, a sampling port 106, a manhole 105, etc.

[0030] In one embodiment, a first control valve 24 is provided on the first branch pipe 21, which can connect or disconnect the first branch pipe 21; a second control valve 25 is provided on the second branch pipe 22, which can connect or disconnect the second branch pipe 22; and a third control valve 26 is provided on the third branch pipe 23, which can connect or disconnect the third branch pipe 23. The connection or disconnection of the first branch pipe 21, the second branch pipe 22, and the third branch pipe 23 is controlled by the first control valve 24, the second control valve 25, and the third control valve 26 respectively, facilitating operation.

[0031] For example, the first control valve 24, the second control valve 25, and the third control valve 26 are all ball valves. When the ball valve is open, pipeline 2 is connected; when the ball valve is closed, pipeline 2 is blocked. The first control valve 24, the second control valve 25, and the third control valve 26 can be manually controlled or electrically controlled, without limitation.

[0032] For example, the first control valve 24 is a vacuum valve, the second control valve 25 is an air vent valve, and the third control valve 26 is an air intake valve.

[0033] Optionally, the first branch pipe 21, the second branch pipe 22, and the third branch pipe 23 are arranged in parallel, and one end of each is connected to the main pipe 27. The first branch pipe 21, the second branch pipe 22, and the third branch pipe 23 are all connected to the reactor 1 through the main pipe 27 for easy connection.

[0034] During vacuuming, first close the first control valve 24 and the second control valve 25, and open the third control valve 26, thus blocking the first branch pipe 21 and the second branch pipe 22, and connecting the third branch pipe 23. Then, turn on the vacuum pump 4 to extract the gas from the reactor 1, i.e., to evacuate the reactor 1. Afterwards, open the first control valve 24, and close the second control valve 25 and the third control valve 26, thus connecting the first branch pipe 21 and blocking the second branch pipe 22 and the third branch pipe 23, allowing purified air to enter the reactor 1 to balance the pressure inside. Before using the reactor 1, evacuate it and introduce purified air into it to balance the pressure within the reactor system and prevent air contamination of the product inside the reactor 1.

[0035] When using reactor 1, close the first control valve 24 and the third control valve 26, and open the second control valve 25. This blocks the first branch pipe 21 and the third branch pipe 23, while connecting the second branch pipe 22. The waste gas generated by reactor 1 can be discharged through the second branch pipe 22 at any time, ensuring internal pressure balance. The structure is simple and the operation is convenient.

[0036] The reactor system also includes a monitoring component. The first control valve 24, the second control valve 25, and the third control valve 26 are all communicatively connected to the monitoring component, which enables the first control valve 24, the second control valve 25, and the third control valve 26 to be opened or closed respectively. For example, multiple operating modes are set. In vacuum mode, the first control valve 24 and the second control valve 25 are closed, and the third control valve 26 is opened, thus blocking the first branch pipe 21 and the second branch pipe 22, and connecting the third branch pipe 23. In gas intake mode, the second control valve 25 and the third control valve 26 are closed, and the first control valve 24 is opened, thus connecting the first branch pipe 21, and blocking the second branch pipe 22 and the third branch pipe 23.

[0037] The other end of the first branch pipe 21 is connected to the outlet of the gas filter 3. The inlet of the gas filter 3 is used to allow air to enter. The air is filtered by the gas filter 3, thereby allowing purified gas to be introduced into the first branch pipe 21.

[0038] Optionally, the reactor system also includes a condenser 107, one end of which is connected to the reactor 1, and the other end is connected to the main pipeline 27. The main pipeline 27 is also provided with a reflux section, and a reflux valve 29 is provided between the reflux section and the reactor 1. In this embodiment, the first branch pipeline 21, the second branch pipeline 22, the third branch pipeline 23, the condenser 107, and the reflux section are sequentially connected to the main pipeline 27. The gas generated in the reactor 1 enters the main pipeline 27 after passing through the condenser 107, and is then discharged through the second branch pipeline 22. The liquid condensed in the condenser 107 returns to the reactor 1 through the reflux section and the reflux valve 29. The main pipeline 27 is also provided with a drain outlet 28, and a control valve is provided at the drain outlet 28, which is opened as needed for drainage.

[0039] The gas filter 3 includes a housing 31, a filter element 32, and a connector 33. The filter element 32 is disposed within the accommodating space formed by the connector 33 and the housing 31. The connector 33 has an inlet 331 and an outlet 332. The inlet 331 connects to the gap 34 formed by the filter element 32 and the housing 31, and the outlet 332 connects to the internal space of the filter element 32, forming the outlet of the gas filter 3. The inlet 331 is the inlet of the gas filter 3. Air enters the gap 34 through the inlet 331, is filtered by the filter element 32, enters the internal space of the filter element 32, and is then discharged from the outlet 332.

[0040] Depending on specific needs, filter element 32 can be made of different materials, and the material can be changed as needed during use. Before use, determine the requirements and the necessary material for filter element 32, then install the gas filter 3. For example, filter element 32 can be a metal filter element, an activated carbon filter element, or a polytetrafluoroethylene (PTFE) filter element. The housing 31 and connector 33 are detachably connected, and the connector 33 and filter element 32 are also detachably connected. Filter element 32 can be replaced as needed. The connector 33 and housing 31 are universal, improving the versatility of the gas filter 3, and making modification convenient and operating at low cost.

[0041] Specifically, the connector 33 is plate-shaped, with a threaded connecting pipe in the middle. The filter element 32 has a threaded boss 321. The bottom of the filter element 32 is supported inside the connector 33, and the outer shell 31 covers the filter element 32. The boss 321 passes through the connecting pipe, and the external thread of the boss 321 is threadedly connected to the thread of the connecting pipe, forming an air outlet 332. An air inlet 331 is provided between the edges of the connecting pipe and the connector 33. The connector 33 is located below the outer shell 31, that is, the air inlet 331 is located below the gas filter 3, which can effectively avoid the impact of airborne dust on the life of the filter element 32 and save on operating costs.

[0042] For example, the outer periphery of the connector 33 is provided with a connecting flange, the outer periphery of the housing 31 is provided with a connecting flange, a sealing ring is provided between the two connecting flanges, and the two connecting flanges are connected by fasteners such as bolts. For example, the outer periphery of the connector 33 is provided with a plurality of first connecting protrusions 333, and the outer periphery of the housing 31 is provided with a plurality of second connecting protrusions 311. The first connecting protrusions 333 of the connector 33 and the second connecting protrusions 311 of the housing 31 correspond one-to-one, and a corresponding pair of first connecting protrusions 333 and second connecting protrusions 311 are connected by clamps 35 for easy replacement and disassembly.

[0043] Multiple air inlets 331 are provided, and the multiple air inlets 331 are evenly arranged around the air outlet 332 to facilitate air intake. By increasing the number of air inlets 331 and the air inlets 331 being evenly distributed, the amount of purified air of the gas filter 3 is increased, and the amount of purified air entering the reactor 1 is increased, saving time and improving work efficiency.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
