Description

Technical Field

[0001] This utility model relates to the field of reactor technology, and in particular to a hydrogenation reactor with uniform hydrogen distribution. Background Technology

[0002] A hydrogenation reactor is a device that operates under high temperature and high pressure. It is mainly used to react hydrogen with other chemical substances to produce more valuable products. In the hydrogenation reaction, uniform distribution of hydrogen can ensure more uniform contact between the reactants and the catalyst and a more complete reaction. Therefore, a hydrogenation reactor with uniform hydrogen distribution is used.

[0003] To address this, patent CN212819791U discloses a continuous hydrogenation reactor with high hydrogen utilization rate, comprising a reactor tank. A support leg is fixedly installed at the bottom of the reactor tank surface, and an overlapping leg is fixedly installed at the bottom end of the support leg. An inlet pipe and an outlet pipe are installed on the tank body. An electric hydraulic cylinder drives the internal output piston rod to extend or retract, thereby causing the support circular plate to rise or fall. This causes the support circular plate to move the support crossarm, support plate frame, support strip frame, and reactor head to rise or fall, allowing the reactor head to be separated from or overlapped with the reactor tank. A dust cover prevents dust accumulation on the output piston rod structure, reducing maintenance costs. This achieves the effect of quick and efficient opening and closing of the reactor head structure, facilitating disassembly and installation, and making operation and maintenance more convenient.

[0004] While the aforementioned continuous hydrogenation reactor with high hydrogen utilization rate achieves the goal of easy disassembly and installation, and is more convenient to use and maintain, its applicability is low due to the inconvenience of filtration and the difficulty in preventing blockage of the flow divider plate. Utility Model Content

[0005] The purpose of this invention is to provide a hydrogenation reactor with uniform hydrogen distribution, in order to solve the problem that existing hydrogenation reactors with uniform hydrogen distribution are inconvenient to filter.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hydrogenation reactor with uniform hydrogen distribution, comprising a reactor body;

[0007] The top of the device is fixed with a cover. A filter structure is installed on one side of the top of the cover. The filter structure includes a filter box fixed to one side of the top of the cover. A filter cylinder is installed inside the filter box. A connecting pipe is fixed to one side of the filter box. Slots are opened on both sides of the top of the filter box. A locking block is installed inside the slot. A reserved slot is installed inside the locking block. The top of the locking block extends to the outside of the filter box and is fixed with a box cover. An air inlet pipe passes through the inside of the box cover.

[0008] A flow-diverting structure is installed at the bottom of the cover, and a stirring structure is provided inside the container.

[0009] An exhaust pipe is fixed to one side of the bottom of the device.

[0010] When using this device, the filtration structure facilitates clogging prevention, thereby improving the applicability of the hydrogenation reactor with uniform hydrogen distribution; the stirring structure facilitates mixing, thereby improving the working efficiency of the hydrogenation reactor with uniform hydrogen distribution; and the diversion structure facilitates uniform distribution, thereby improving the convenience of using the hydrogenation reactor with uniform hydrogen distribution.

[0011] Preferably, a feed inlet is provided on one side of the top of the cover, and support legs are evenly fixed on both sides of the bottom of the device.

[0012] Preferably, a discharge port is fixed at the bottom of the device, and a safety valve is installed inside the exhaust pipe. Under the action of the safety valve, when the internal pressure of the device exceeds a set value, the safety valve will automatically open, allowing the gas to be discharged to the outside of the device through the exhaust pipe, preventing the device from exploding due to excessive pressure.

[0013] Preferably, the bottom end of the connecting pipe extends into the interior of the cover, one end of the air inlet pipe is fixed with a flange, the locking block and the filter box form an engaging structure through a locking groove, and handles are fixed on both sides of the cover. The filter cartridge facilitates the filtration of hydrogen gas. The filtered hydrogen gas enters the interior of the device through the connecting pipe, preventing blockage of the flow divider. Moving the cover with the handles causes the cover to move the locking block to the outside of the locking groove, at which point the cover and the filter box separate, allowing for cleaning of the filter cartridge.

[0014] Preferably, the stirring structure includes a drive motor, a stirring shaft, stirring blades, a support, and a connecting shaft. The stirring shaft is disposed inside the vessel body, and a support is provided on the outer side of the bottom of the stirring shaft. Stirring blades are uniformly fixed on the outer wall of the stirring shaft. The drive motor is installed at the top of the cover above the stirring shaft, and the output end of the drive motor extends into the interior of the cover and is fixed to the connecting shaft. The support enhances the stability of the stirring shaft during rotation, and the stirring shaft drives the stirring blades to stir the reactants inside the vessel body.

[0015] Preferably, the stirring blade has uniformly perforated holes inside, the bottom end of the support is fixedly connected to the inner wall of the vessel, and the bottom end of the connecting shaft extends into the interior of the vessel and is fixedly connected to the top end of the stirring shaft. The perforations reduce the resistance of the stirring blade during rotation, and the stirring blade ensures thorough mixing of the reactants inside the vessel.

[0016] Preferably, the diversion structure includes a fixing ring, a diversion plate, and diversion holes. The fixing ring is fixed to the bottom of the cover, and the diversion plate is fixed to the bottom end of the fixing ring. Diversion holes are uniformly penetrated inside the diversion plate.

[0017] Preferably, one side of the flow divider plate is provided with a through hole adapted to the bottom end of the feed inlet, and the flow divider holes are evenly distributed inside the flow divider plate. Hydrogen enters the interior of the reactor body through the flow divider holes, and under the action of the evenly spaced flow divider holes, the hydrogen is evenly distributed inside the reactor body, thereby ensuring more uniform contact between the reactants and the catalyst and a more complete reaction.

[0018] The hydrogenation reactor with uniform hydrogen distribution provided by this utility model has the following advantages:

[0019] With a filtration structure and flange, it is easy to connect to external hydrogen. When the locking block moves into the slot, the cover and filter box are fixed together, and hydrogen enters the filter cartridge through the inlet pipe. The filter cartridge facilitates the filtration of hydrogen. The filtered hydrogen enters the interior of the reactor body through the connecting pipe, preventing blockage of the flow divider. By moving the cover with the handle, the cover moves the locking block to the outside of the slot, at which point the cover and filter box separate, allowing for cleaning of the filter cartridge. This device has an easy anti-clogging function, thereby improving the applicability of the hydrogenation reactor with uniform hydrogen distribution during use.

[0020] By incorporating a stirring structure and supported by a base, the stability of the stirring shaft during rotation is enhanced. The stirring shaft drives the stirring blades to stir the reactants inside the reactor. The through-holes reduce the resistance of the stirring blades during rotation. The stirring blades ensure thorough mixing of the reactants inside the reactor, thus facilitating mixing and improving the working efficiency of the hydrogenation reactor with uniform hydrogen distribution.

[0021] By incorporating a flow-dividing structure, hydrogen enters the interior of the reactor body through the flow-dividing holes. Under the action of the equally spaced flow-dividing holes, the hydrogen is evenly distributed inside the reactor body, thereby ensuring more uniform contact between the reactants and the catalyst and a more complete reaction. This achieves the function of facilitating uniform distribution of hydrogen, thus improving the convenience of using this hydrogenation reactor with uniform hydrogen distribution.
