Description

Technical Field

[0001] This application relates to the field of catalytic reaction equipment technology, and in particular to a catalytic reactor for the production of methylhydrazine and its method of use. Background Technology

[0002] Methylhydrazine is an important chemical intermediate. It is a colorless to slightly yellow liquid at room temperature, readily soluble in water, ethanol, and ether. It has reducing properties and is highly toxic. It is widely used in pharmaceuticals, pesticides, and rocket propellants. There are many methods for its synthesis, such as the benzaldehyde condensation method of hydrazine hydrate, the hydrazine hydrate method of dimethyl phosphite or dimethyl carbonate, the hydrazine-ethanol decomposition method, and the hydrazine hydrate method of dimethyl sulfate.

[0003] In related technologies, a method for catalytic synthesis of methylhydrazine under normal pressure uses a batch reactor as the catalytic reaction vessel to prepare methylhydrazine by one-step reaction of hydrazine hydrate with methanol or with chloromethane.

[0004] Regarding the aforementioned technologies, in the catalytic production process of methylhydrazine, the catalyst and other materials are usually directly introduced into the raw materials of the reaction vessel, and then manually stirred and mixed. The catalyst and other materials are mainly concentrated in one place inside the vessel, resulting in low stirring and mixing efficiency of the catalyst and materials, which affects the final catalytic reaction efficiency of the raw materials. Furthermore, since methylhydrazine is highly toxic, the manual stirring process can easily cause safety hazards, so improvements are needed. Summary of the Invention

[0005] In order to improve the catalytic reaction efficiency of materials and catalysts and enhance production safety, this application provides a catalytic reactor for the production of methylhydrazine and a method for using it.

[0006] Firstly, this application provides a catalytic reactor for the production of methylhydrazine, which adopts the following technical solution:

[0007] A catalytic reactor for the production of methylhydrazine includes a vessel body and a feed inlet extending through the top of the vessel body. Inside the feed inlet, the vessel body has a material dispersing component. A feed box is located on one side of the vessel body, and a feed pump is connected between the feed box and the material dispersing component. The vessel body has a rotating assembly for driving the material dispersing component to rotate, a lifting assembly for driving the material dispersing component to rise and fall, and a protective cover for enclosing the material dispersing component, the rotating assembly, and the lifting assembly.

[0008] By adopting the above technical solution, the feed pump and feed box deliver catalyst and other materials into the bulk component, which disperses the materials into the reactor body. The rotating component drives the bulk component to rotate, and the lifting component drives the bulk component to rise and fall, increasing the range of material dispersion by the bulk roller, thereby improving the mixing efficiency of the materials and the catalytic reaction efficiency of methylhydrazine. The automated feeding and mixing of materials inside the reactor body reduces manual intervention steps and improves production safety. The protective cover protects the structure at the top of the reactor body, ensuring the pressure requirements during the catalytic reaction process and reducing the phenomenon of internal material leakage during the catalytic reaction, thus improving the overall safe use of the catalytic reactor.

[0009] Preferably, the bulk material component includes a rotating roller and a bulk material roller; the rotating roller is disposed inside the feed inlet, the bulk material roller is disposed at the end of the rotating roller, and the bulk material roller is located inside the reactor body; the rotating roller has a flow cavity for material flow, the bulk material roller has a bulk material cavity communicating with the flow cavity, and the peripheral wall of the bulk material roller has a plurality of bulk material holes communicating with the bulk material cavity, and all the bulk material holes are spaced apart along the length direction of the bulk material roller.

[0010] By adopting the above technical solution, the rotating roller and the dispersing roller are internally connected, so as to facilitate the transport of materials to the inside of the dispersing roller and the dispersion of materials into the raw materials inside the reactor through the dispersing holes. This increases the range of material dispersion by the dispersing roller, thereby facilitating the improvement of the mixing efficiency of raw materials and catalysts and the catalytic reaction efficiency of methylhydrazine.

[0011] Preferably, the rotating assembly includes a mounting block, a rotary joint, a fixed tube, a fixed gear ring, a rotating gear, and a rotating motor; the mounting block is disposed on the top of the vessel body, the rotary joint is disposed on the mounting block, the rotating roller is rotatably connected to the mounting block, and the rotary joint communicates with the flow cavity inside the rotating roller; the fixed tube is disposed on the mounting block, the interior of the fixed tube communicates with the rotary joint, and the fixed tube is connected to the feed pump; the fixed gear ring is disposed on the rotating roller, the rotating gear is rotatably disposed on the mounting block, and the fixed gear ring and the rotating gear mesh with each other; the rotating motor is disposed on the mounting block to drive the rotating gear to rotate.

[0012] By adopting the above technical solution, the rotating motor uses rotating gears and fixed gear rings to drive the rotating roller to rotate the material distribution roller. The rotating material distribution roller stirs and mixes the raw materials and catalysts inside the reactor, and increases the dispersion range of the materials, thereby facilitating the improvement of the mixing efficiency of raw materials and catalysts and the catalytic reaction efficiency of methylhydrazine.

[0014] By adopting the above technical solution, the output end of the lifting motor drives the lifting screw, causing the lifting screw to rotate. The rotating lifting screw drives the mounting block, causing the lifting and moving mounting block to drive the rotating roller and the material dispersing roller to move up and down, further increasing the range of material dispersion by the material dispersing roller, thereby improving the mixing efficiency of the material and the catalytic reaction efficiency of methylhydrazine.

[0015] Preferably, the material distribution roller is provided with a sealing component for sealing the material distribution hole.

[0016] By adopting the above technical solution, after the material is dispersed, the sealing component seals the dispersing hole, reducing the blockage caused by the crystals generated by the catalytic reaction of the material, and ensuring the stable use of the dispersing component in the future.

[0017] Preferably, the sealing assembly includes a fixed rod, a sliding sleeve, a positioning rod, a sealing ring plate, a fixing plate, an elastic element, and a driving element; the fixed rod is disposed inside the material distribution roller, the sliding sleeve is slidably disposed at both ends of the material distribution roller along its length, the positioning rod is disposed on the outer peripheral wall of each set of sliding sleeves, the sealing ring plate is disposed at the end of the positioning rod away from the sliding sleeve, and the side wall of the sealing ring plate away from the positioning rod is in contact with the inner side wall of the material distribution cavity to seal the material distribution hole; the fixing plate is disposed in the middle of the material distribution roller, the elastic element is disposed between the fixing plate and each set of sliding sleeves to drive the sliding sleeve away from the fixing plate through its own elastic force; the driving element is disposed inside the material distribution roller to drive the sliding sleeve closer to the fixing plate, and to cause the sealing ring plate to seal the material distribution hole.

[0018] By adopting the above technical solution, the driving component drives the two sets of sliding sleeves to approach each other, and causes the elastic component to deform and contract to accumulate elastic potential energy, so that the sealing plate gradually seals the material outlet, reducing the phenomenon of crystals generated by the catalytic reaction inside the reactor blocking the material outlet; after the driving component removes the force on the sliding sleeves, the elastic component gradually recovers its deformation and drives the two sets of sliding sleeves to move away from each other, and causes the sealing ring plate and the material outlet to be misaligned, so that the material inside the material outlet cavity can be dispersed into the raw material inside the reactor through the material outlet.

[0019] Preferably, the closure assembly further includes an extension ring plate and a crushing rod; the extension ring plate is disposed on the side wall of the closure ring plate, and the side wall of the extension ring plate away from the sliding sleeve is in contact with the inner side wall of the material dispersing cavity; the crushing rod is disposed on the side wall of the extension ring plate away from the sliding sleeve, and the end of the crushing rod away from the extension ring plate passes through the material dispersing hole.

[0020] By adopting the above technical solution, the crushing rod can crush the crystals adhering inside the material dispersing hole as it moves with the closed ring plate, reducing the phenomenon of crystals blocking the material dispersing hole; the extended ring plate increases the area of ​​the closed ring plate, so as to more stably seal the material dispersing hole.

[0021] Preferably, the driving component includes a wire harness ring, a pull rope, a traction rope, a rotating disk, and a driving cylinder; the wire harness ring is disposed inside the rotating roller, the pull rope is disposed at the end of each set of sliding sleeves facing the fixed plate, and the end of each pull rope away from the sliding sleeve passes through the wire harness ring; the traction rope slides through the rotating roller; the rotating disk is disposed at the ends of the two sets of pull ropes and traction ropes facing each other, and the two sets of rotating disks are rotatably connected; the driving cylinder is disposed on the fixed tube for driving the traction rope to move.

[0022] By adopting the above technical solution, the output end of the drive cylinder extends to gradually stretch the traction rope, and the traction rope drives the pull rope to move away from the material distribution roller, so that the two sets of sliding tubes move closer to each other and the closing ring plate moves to close the material distribution hole; the wire harness ring restricts the movement direction of the pull rope, and the rotating disk allows the pull rope to rotate with the traction rope, and the traction rope and the pull rope pull each other.

[0023] Preferably, the top of the vessel body is provided with a gas guide ring pipe around the bulk material, and the inner side wall of the gas guide ring pipe is provided with a number of exhaust nozzles for blowing the bulk material. The vessel body is provided with a gas supply component for supplying gas to the gas guide ring pipe.

[0024] By adopting the above technical solution, the air supply component delivers airflow into the exhaust nozzle, and the airflow is discharged through the air guide ring pipe and the exhaust nozzle to blow the material adhering to the surface of the bulk material and return it to the inside of the reactor body, thereby reducing the phenomenon of material following the bulk material through the feed inlet and leaving the reactor body.

[0025] Secondly,

[0026] This application provides a method for using a catalytic reactor for the production of methylhydrazine, comprising the following steps:

The rotating component drives the bulk material component to rotate, and the lifting component drives the bulk material component to rise and fall, increasing the range of material dispersion by the bulk roller, thereby improving the mixing efficiency of the materials and the catalytic reaction efficiency of methylhydrazine, and improving the overall safety of the catalytic reactor. The automated feeding and mixing of materials inside the reactor body reduces manual steps and improves production safety.

[0032] By sealing the dispersing orifice with a closed component, the blockage caused by crystal formation from the catalytic reaction of the material after the material is dispersed is reduced, ensuring the stable use of the dispersing component in the future.

[0033] By setting up an air supply component to deliver airflow into the exhaust nozzle, the airflow is discharged through the air guide ring pipe and the exhaust nozzle to blow the material adhering to the surface of the bulk material and return it to the inside of the reactor body, thereby reducing the phenomenon of material following the bulk material through the feed inlet and leaving the reactor body.
