Description

Technical Field

[0001] The utility model belongs to the technical field of morpholine vaporization production, in particular to a high-efficiency vaporization device for a morpholine reactor. Background Art

[0002] Morpholine is one of the most important industrial cyclic amines and is a colorless, hydroscopic, oily liquid. Morpholine's synthesis routes, depending on the raw materials used, include diethanolamine dehydration, catalytic hydrogenation of dicyanomethyl ether, catalytic amination of ethylene oxide, dechlorination and amination cyclization of dichloroethyl ether, amine dehydration and cyclization, and catalytic ammonia decyclization of diethylene glycol. When using the catalytic amination of ethylene oxide, both ethylene oxide and morpholine must be vaporized to ensure that the reactants participate in the chemical reaction in a vapor state, thereby improving reaction efficiency and yield.

[0003] Patent CN201922262903.8 mentions an ethylene oxide vaporization device that uses a spiral vaporization tube to heat the reactant liquid to accelerate its vaporization. However, the liquid reactant has a small contact area with the air, which will prolong the vaporization time of the reactant. Utility Model Content

[0004] The present invention addresses the problem in the prior art that the liquid reactant has a small contact area with the air and a long vaporization time, and proposes the following technical solutions:

[0005] The invention discloses a high-efficiency vaporization device for a morpholine reactor, comprising: a liquid vaporization tank, a diffusion chamber provided in the middle of the liquid vaporization tank, a plurality of liquid spraying ports provided on the surface of the diffusion chamber, a mounting block and an air outlet provided on the top of the liquid vaporization tank, a liquid inlet provided on one side of the mounting block, a liquid inlet pipe fixedly connected to the bottom of the mounting block, and one end of the liquid inlet pipe inserted into the interior of the diffusion chamber.

[0006] As a preferred embodiment of the above technical solution, an adjustment device is provided inside the diffusion chamber, and the adjustment device includes a sealing ring and a driving cylinder. The inner and outer sides of the sealing ring are respectively fitted with the outer surface of the liquid inlet pipe and the inner surface of the diffusion chamber. The bottom of the sealing ring is fixedly connected to a movable frame, and the other end of the movable frame passes through the liquid inlet pipe and extends to the outside of the liquid vaporization tank, and the end of the movable frame is fixedly connected to the output end of the driving cylinder.

[0007] As a preferred embodiment of the above technical solution, a heating plate is sleeved on the outer surface of the liquid vaporization tank, a spiral water channel is provided inside the heating plate, and a water inlet and a water outlet are respectively provided at both ends of the spiral water channel.

[0008] As a preferred embodiment of the above technical solution, a drain port is provided at the bottom of the liquid vaporization tank, and the drain port is used to discharge the gas inside the tank body to maintain a stable pressure.

[0009] The beneficial effects of the utility model are:

[0010] 1. After the liquid reactant enters the diffusion chamber from the liquid inlet pipe, it can be split into several small liquid streams and sprayed out through the several liquid spray ports on the surface of the diffusion chamber. This can increase the contact area between the liquid reactant and the air, causing it to be quickly heated and the vaporization speed to increase, thereby significantly reducing the vaporization time of the liquid reactant;

[0011] 2. The reciprocating movement of the sealing ring changes the size of the internal space of the diffusion chamber. Without changing the flow rate of the injected liquid reactant, the internal pressure of the diffusion chamber changes periodically, and the path of the liquid reactant sprayed from the liquid nozzle changes periodically, thereby quickly diffusing the liquid reactant into the liquid vaporization tank, further accelerating the vaporization process of the liquid reactant.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0017] Example

[0018] Figure 1-Figure 3 In the embodiment, a high-efficiency vaporization device for a morpholine reactor comprises: a liquid vaporization tank 10, a diffusion chamber 20 is provided in the middle of the liquid vaporization tank 10, a plurality of liquid spray ports 30 are provided on the surface of the diffusion chamber 20, a mounting block 11 and an air outlet 14 are provided on the top of the liquid vaporization tank 10, a liquid inlet 13 is provided on one side of the mounting block 11, a liquid inlet pipe 40 is fixedly connected to the bottom of the mounting block 11, and one end of the liquid inlet pipe 40 is inserted into the interior of the diffusion chamber 20.

[0019] The bottom of the liquid vaporization tank 10 is provided with a drain port 12, and the drain port 12 is used to discharge the gas inside the tank body to maintain a stable pressure.

[0020] After the liquid reactant enters the diffusion chamber 20 from the liquid inlet pipe 40, the liquid reactant can be diverted into several small liquid streams through the several liquid spraying ports 30 on the surface of the diffusion chamber 20, thereby increasing the contact area between the liquid reactant and the air, causing it to be quickly heated and increasing the vaporization rate, thereby significantly reducing the vaporization time of the liquid reactant.

[0021] Figure 2-Figure 3 In the diffusion chamber 20, an adjustment device is provided inside the diffusion chamber 20, and the adjustment device includes a sealing ring 51 and a driving cylinder 52. The inner and outer sides of the sealing ring 51 are respectively fitted with the outer surface of the liquid inlet pipe 40 and the inner surface of the diffusion chamber 20. The sealing ring 51 is provided with a rubber layer at the fitting position of the outer surface of the liquid inlet pipe 40 and the inner surface of the diffusion chamber 20. The bottom of the movable sealing ring 51 is fixedly connected to a movable frame 53, and the other end of the movable frame 53 passes through the liquid inlet pipe 40 and extends to the outside of the liquid vaporization tank 10, and the end of the movable frame 53 is fixedly connected to the output end of the driving cylinder 52.

[0022] The sealing ring 51 is used to reciprocate to change the size of the internal space of the diffusion chamber 20. Without changing the flow rate of the injected liquid reactant, the internal pressure of the diffusion chamber 20 changes periodically, and the path of the liquid reactant sprayed out of the liquid nozzle 30 changes periodically, thereby quickly diffusing the liquid reactant into the liquid vaporization tank 10, further accelerating the vaporization process of the liquid reactant.

[0023] Figure 1 In the embodiment, a heating plate 60 is sleeved on the outer surface of the liquid vaporization tank 10 , a spiral water channel is provided inside the heating plate 60 , and a water inlet 61 and a water outlet 62 are respectively provided at both ends of the spiral water channel of the heating plate 60 .

[0024] Hot water is continuously introduced into the heating plate 60 from the water inlet 61 , and continuously passes through the spiral water channel of the heating plate 60 and is discharged from the water outlet 62 to heat the liquid vaporization tank 10 and keep it warm, ensuring that the internal temperature of the liquid vaporization tank 10 is higher than the reaction temperature.

[0025] Working principle: When the liquid reactant is vaporized, hot water is continuously introduced into the heating plate 60 from the water inlet 61, and the hot water continuously passes through the spiral water channel of the heating plate 60 and is discharged from the water outlet 62 to heat the liquid vaporization tank 10 and keep it warm, ensuring that the internal temperature of the liquid vaporization tank 10 is higher than the reaction temperature. Then, the liquid reactant is introduced into the liquid inlet pipe 40 from the mounting block 11 at the liquid inlet 13 position, and the liquid reactant flows through the liquid inlet pipe 40 into the diffusion chamber 20 for temporary storage. The several liquid spray ports 30 on the surface of the diffusion chamber 20 can divert the liquid reactant into several small liquid flows to increase the contact area between the liquid reactant and the air. At the same time, the driving cylinder 52 is started to drive the sealing ring 51 to move back and forth through the movable frame 53, and the size of the internal space of the diffusion chamber 20 changes accordingly. Without changing the flow rate of the injected liquid reactant, the spray path of the liquid reactant after passing through the liquid spray port 30 is changed, thereby quickly diffusing the liquid reactant into the liquid vaporization tank 10, further accelerating the vaporization process of the liquid reactant.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
