Description

Technical Field

[0001] The present application belongs to the field of chemical technology, and specifically relates to a reactor structure capable of recovering reaction raw materials. Background Art

[0002] For reversible reactions, it is necessary to remove the product or by-product from the system in time to make the target reaction more thorough, so that the conversion rate is improved. For reversible reactions in which the by-product is water, the prior art generally introduces gas (which can be raw material gas or non-raw material gas) into the reactor, and removes the by-product water from the system through the gas, thereby improving the raw material conversion rate. However, for reaction raw materials (such as solvents) whose boiling point is close to the reaction temperature, they are easily taken out together with the gas, which increases the loss of materials and improves production costs.

[0003] Therefore, in view of this, the inventor, based on his many years of rich experience in design, development and actual production in the relevant industry, has studied and improved the existing structure and deficiencies, and provided a reactor structure that can recycle reaction raw materials, in order to achieve a more practical purpose. Utility Model Content

[0004] In order to solve the problems mentioned in the above background technology, the utility model provides a reactor structure capable of recovering reaction raw materials.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A reactor structure capable of recovering reaction raw materials comprises a reactor, a receiving tank, a water separator and a moisture receiving device. The reactor is connected to the water separator through a connecting pipe, a jacket is sleeved on the connecting pipe, the bottom of the water separator is connected to the moisture receiving device, and the water separator is connected to the receiving tank through a gas transmission pipe.

[0007] Preferably, a valve is provided in the connecting pipe for controlling the pressure in the reactor.

[0008] Preferably, a liquid outlet pipe is provided at the bottom of the water distributor, a second valve is provided on the liquid outlet pipe, a third valve is provided on the gas pipe, a guide plate is provided on the inner wall of the water distributor near the bottom, a drain pipe is provided at the bottom of the guide plate, and a first one-way valve is provided on the drain pipe.

[0009] Preferably, a first separation mechanism is provided on the inner wall of the water divider, and a second separation mechanism is provided on the inner wall of the water divider above the first separation mechanism.

[0010] Preferably, the first separation mechanism includes a connecting plate fixedly connected to the inner wall of the water separator, a separation shell is provided on the connecting plate, a steam inlet is provided at the bottom of the separation shell, a rotary vane is rotatably connected to the side of the separation shell, a steam outlet pipe is provided at the top of the first separation mechanism, and a second one-way valve is provided on the steam outlet pipe.

[0011] Preferably, the second separation mechanism includes a water collecting tray and a connecting frame fixedly connected to the side wall of the water distributor, the connecting frame is detachably connected to a fixing frame, a fine filter plate is provided in the fixing frame, the bottom of the water collecting tray is connected to the bottom of the water distributor through a guide pipe, and a third one-way valve is provided on the guide pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. A cooling medium is introduced into the jacket, and the reaction raw materials in the connecting pipe carried out by the gas are condensed and refluxed to the reactor under the action of the cooling medium. The temperature of the cooling medium in the jacket needs to be adjusted in combination with the gas flow rate, the temperature in the reactor, the boiling point of the low-boiling-point reaction raw materials, the boiling point of water, etc., so that the low-boiling-point reaction raw materials (such as solvents) are condensed and refluxed into the reactor, and the gaseous water carried out will not condense at the jacket, and the reaction raw materials in the connecting pipe carried out by the gas are condensed and refluxed to the reactor under the action of the cooling medium. Therefore, the reactor structure of the utility model that can recycle the reaction raw materials can reduce material loss and reduce production costs.

[0014] 2. Through the setting of the valve, when the reactor is reacting under pressure, the valve is in a normally closed state. When the pressure exceeds the preset pressure, the valve opens to relieve the pressure of the reactor.

[0015] 3. Water vapor enters the water separator, and after condensation, it is separated into steam and water by the first separation mechanism and the second separation mechanism. The separated water drops onto the guide plate, flows from the drain pipe to the bottom of the water separator, and is discharged through the liquid outlet pipe. This can maximize the recovery of water in the steam generated during the reaction process, thus saving water resources.

[0016] In summary, the utility model overcomes the shortcomings of the prior art, has a reasonable design, wide applicability, and has high social use value and application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1-8 As shown, a reactor structure for recovering reaction raw materials includes a reactor 1, a receiving tank 2, a water separator 6 and a moisture receiving device 7. The reactor 1 is connected to the water separator 6 through a connecting pipe 3, a jacket 4 is sleeved on the connecting pipe 3, the bottom of the water separator 6 is connected to the moisture receiving device 7, and the water separator 6 is connected to the receiving tank 2 through a gas pipe 21.

[0030] A reversible reaction can be carried out in the reactor 1. Gas (which can be raw material gas or non-raw material gas) is introduced into the reactor 1 to bring out the by-products (such as moisture) generated in the reactor 1. Part of the raw materials in the reactor 1 (i.e., the raw materials with boiling points close to the reaction temperature) will evaporate and be brought out by the gas. A cooling medium is introduced into the jacket 4. The raw materials in the connecting pipe 3 brought out by the gas are condensed and refluxed to the reactor 1 under the action of the cooling medium. The temperature of the cooling medium in the jacket 4 needs to be adjusted in combination with the gas flow rate, the temperature in the reactor, the boiling point of the low-boiling-point raw materials, the boiling point of water, etc., so that the low-boiling-point raw materials (such as solvents) are condensed and refluxed into the reactor 1, and the gaseous moisture brought out will not condense at the jacket 4. The raw materials in the connecting pipe 3 brought out by the gas are condensed and refluxed to the reactor 1 under the action of the cooling medium. Therefore, the reactor structure of the utility model capable of recovering raw materials can reduce material loss and production costs.

[0031] The flow direction of the cooling medium in the jacket 4 is the same as the flow direction of the gas in the connecting pipe 3 at the jacket 4. In this way, the evaporated reaction raw materials in the connecting pipe 3 at the jacket 4 can be fully heat-exchanged with the cooling medium, so as to cool the evaporated reaction raw materials in the connecting pipe 3 at the jacket 4, condense them and reflux them into the reactor 1.

[0032] The shape of the jacket 4 is not limited. For example, it can be formed into a tube shape so that the cooling medium can be passed through it, and its longitudinal section can be formed into a rectangle so as to be sleeved outside the connecting pipe 3.

[0033] Example 2

[0034] Reference Figure 1-8 The difference between this embodiment and embodiment 1 is that a valve 31 is provided in the connecting pipe 3. When the reactor 1 is subjected to a normal pressure reaction, the valve 31 is in a normally open state, that is, the valve 31 is usually in an open state, so that when the reactor 1 is subjected to a chemical reaction, gas and water can enter the tail gas receiving tank 2. When the reaction is not required or the reactor structure needs to be repaired, the valve 31 can be manually closed. When the reactor 1 is subjected to a pressure reaction (i.e., a chemical reaction that needs to be carried out under a certain pressure), the valve 31 is in a normally closed state. When the preset pressure is exceeded, the valve 31 is opened to relieve the pressure of the reactor 1.

[0035] Example 3

[0036] Reference Figure 1-8The difference between this embodiment and embodiment 2 is that a liquid outlet pipe 62 is provided at the bottom end of the water divider 6, a second valve 601 is provided on the liquid outlet pipe 62, a third valve 602 is provided on the gas pipe 21, a guide plate 61 is provided near the bottom end of the inner wall of the water divider 6, a drain pipe 611 is provided at the bottom of the guide plate 61, a first one-way valve 612 is provided on the drain pipe 611, a first separation mechanism 63 is provided on the inner wall of the water divider 6, and a second separation mechanism 64 is provided on the inner wall of the water divider 6 above the first separation mechanism 63.

[0037] Water vapor enters the water separator 6, and after condensation, it is separated into steam and water by the first separation mechanism 63 and the second separation mechanism 64. The separated water drops onto the guide plate 61, flows from the drain pipe 611 to the bottom of the water separator 6, and is discharged through the liquid outlet pipe 62, which can maximize the recovery of water in the steam generated during the reaction process and save water resources.

[0038] Example 4

[0039] Reference Figure 1-8 The difference between this embodiment and embodiment 3 is that the first separation mechanism 63 includes a connecting plate 631 fixedly connected to the inner wall of the water separator 6, a separation shell 632 is provided on the connecting plate 631, a steam inlet 633 is provided at the bottom of the separation shell 632, a rotary vane 635 is rotatably connected to the side of the separation shell 632, a steam outlet pipe 636 is provided at the top of the first separation mechanism 63, and a second one-way valve 6361 is provided on the steam outlet pipe 636.

[0040] The cooled water vapor passes through the rotary blade 635, which starts to rotate, thereby driving the steam to form a vortex. The centrifugal force of the vortex can further separate the water in the steam. Small water droplets are thrown onto the side wall of the separation shell 632 by the centrifugal force and fall onto the guide plate 61 for discharge, thereby achieving steam-water separation.

[0041] Example 5

[0042] Reference Figure 1-8 The difference between this embodiment and embodiment 4 is that the second separation mechanism 64 includes a water collecting tray 641 and a connecting frame 642 fixedly connected to the side wall of the water distributor 6, the connecting frame 642 is detachably connected with a fixing frame 643, a fine filter plate 6431 is arranged in the fixing frame 643, the bottom of the water collecting tray 641 is connected with the bottom of the water distributor 6 through a guide pipe 644, a third one-way valve 6441 is arranged on the guide pipe 644, a locking groove 6421 is arranged on the connecting frame 642, a rotating shaft 6432 is rotatably connected to the fixing frame 643, a locking block 6433 is arranged at the bottom of the rotating shaft 6432, the locking block 6433 abuts against the bottom end of the connecting frame 642, and a torsion spring 6434 is sleeved on the rotating shaft 6432.

[0043] The water is further filtered through the fine filter plate 6431, and the separated water falls into the water collecting tray 641. The water in the water collecting tray 641 flows from the guide pipe 644 to the bottom of the water distributor 6 and is then discharged. When the fine filter plate 6431 needs to be cleaned, the rotating shaft 6432 is rotated to lift and remove the fixed frame 643 for easy cleaning or replacement.

[0044] Working principle: When the reactor 1 starts to carry out a reversible reaction, gas is introduced into the reactor 1, and the gas takes out the by-products (such as water) produced by the reactor 1, and also takes out some of the reaction raw materials whose boiling points are close to the reaction temperature. When the water and the reaction raw materials taken out pass through the jacket 4, the reaction raw materials are cooled by the cooling medium in the jacket 4 and condensed and flow back to the reactor 1, while the water does not condense and enters the water separator 6. Part of the gaseous water is cooled and condensed by air in the water separator 6 and flows into the water receiving device 7, and the other part of the gaseous water enters the tail gas receiving tank 2, thereby realizing the recovery of the reaction raw materials.
