Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a high-efficiency separation device for producing methoxyethyl methacrylate. Background Art

[0002] Methyl methacrylate (MMA) is an important organic chemical raw material and chemical product. It can be self-polymerized or copolymerized with other monomers to produce methyl methacrylate resins and plastics, such as organic glass (PMMA), methyl methacrylate-styrene-butadiene (MBS) resin, etc. It can also be used as the second monomer in acrylic fiber production, resins, adhesives, coatings, medical functional materials, etc., and has a wide range of uses.

[0003] After searching, the patent with patent announcement number CN220327943U discloses a new type of high-efficiency methacrylic acid separation tower for producing MMA by acetone cyanohydrin method. Although the device adds ammonia to neutralize the small amount of methacrylic acid contained in the steam to prevent its polymerization and blockage of the tower plate, and also can add an inhibitor to increase the deacidification amount of methacrylic acid and prevent polymerization, thereby improving the efficiency of separating methacrylic acid, the device only separates methacrylic acid through multi-stage tower plates when in use, and the steam is only naturally cooled, the separation rate of methacrylic acid in the steam is slow, which leads to low separation efficiency of methacrylic acid. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high-efficiency separation device for producing methoxyethyl methacrylate, which solves the problems raised in the background technology.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] A high-efficiency separation device for producing methoxyethyl methacrylate, comprising a tank body, a condenser group is arranged in the tank body, an inspection port is installed at the top of the tank body, a feed port is installed at the bottom of the tank body, a liquid outlet is installed at one side of the tank body, and a material outlet and a liquid inlet are installed at the side of the tank body away from the liquid outlet;

[0007] The condenser tube group is provided with a conduit, and a reflux pipe is provided around the conduit. Second partition plates are installed at both ends of the reflux pipe. One end of the conduit passes through the second partition plate and is connected to the first partition plate. A support plate is installed on the outer side of the reflux pipe between the second partition plates, and a through hole is opened on the support plate.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the inner top of the tank body is separated into a first cache cavity by a second partition plate at the top of the condensation tube group.

[0010] The beneficial effects of adopting the above further scheme are:

[0011] The first buffer cavity is provided so that the raw gas or steam condensed by the conduit of the condensing tube group can be further stabilized in this area, slowing down its flow speed, thereby increasing the contact time with the coolant and improving the condensation efficiency. The condensed liquid can accumulate in the first buffer cavity and then flow into the collection cavity through the reflux pipe.

[0012] Furthermore, the inner bottom end of the tank body is separated into a second cache cavity by a first partition plate.

[0013] The beneficial effects of adopting the above further scheme are:

[0014] The second buffer cavity allows the raw materials to be temporarily stored in this area before entering the condenser tube group, thereby playing a buffering role, helping to stabilize the supply of raw materials and reduce the impact of unstable raw material supply on the condensation and separation process. By separating the second buffer cavity, the rate and amount of raw materials entering the condenser tube group can be more flexibly controlled, adjusted according to production needs, and the controllability and stability of the production process can be improved.

[0015] Furthermore, a collecting chamber is separated from the tank body above the second buffer chamber by a first partition plate and a second partition plate, and the discharge port is located at the collecting chamber.

[0016] The beneficial effects of adopting the above further scheme are:

[0017] The setting of the collection chamber allows the methoxyethyl methacrylate after condensation and reflux to be concentrated in this area, which is convenient for subsequent collection and discharge. This design simplifies the separation and collection process and improves production efficiency. By separating the collection chamber from the condensation tube group and the second buffer chamber, impurities and incompletely condensed gases can be reduced from entering the collection chamber, thereby improving the purity and quality of the collected product.

[0018] Furthermore, the liquid inlet and the liquid outlet are located between the two second partition plates of the condenser tube group, so as to facilitate the circulation of the coolant between the second partition plates of the condenser tube group and condense the raw materials in the conduit and the reflux tube.

[0019] The beneficial effects of adopting the above further scheme are:

[0020] The liquid inlet and the liquid outlet are arranged between the two second partition plates to ensure that the coolant can flow evenly and fully through the condensing tube group and the return tube. This design allows the coolant to fully contact the raw materials in the conduit and the return tube, improves the heat exchange efficiency, and thus accelerates the condensation speed of the raw materials.

[0021] Furthermore, the second cache chamber is communicated with the first cache chamber through a conduit, and the first cache chamber is communicated with the collection chamber through a reflux pipe.

[0022] The beneficial effects of adopting the above further scheme are:

[0023] This design allows the raw materials to continuously flow from the second buffer chamber through the conduit into the first buffer chamber, and then enter the collection chamber after the condensation and reflux process. This continuous flow path ensures the continuity and stability of the production process, and avoids the decline in production efficiency or equipment failure caused by the interruption or accumulation of raw materials. The condensed liquid flows back to the collection chamber through the reflux pipe, while the gas that is not completely condensed may continue to circulate in the first buffer chamber until it is completely condensed. This design optimizes the condensation effect, improves the condensation efficiency, and ensures the full condensation of the raw materials. By dividing the condensation and reflux processes into two independent but interconnected areas (the first buffer chamber and the collection chamber), this design helps to improve the separation efficiency. The condensed liquid can quickly and accurately enter the collection chamber, reducing the residence time in the equipment and possible impurity mixing, thereby improving the purity and quality of the product.

[0024] Furthermore, the inspection port is used to connect to a buffer tank to further buffer the raw materials, or the inspection port is used to connect to a cleaning device.

[0025] The beneficial effects of adopting the above further scheme are:

[0026] The inspection port is designed to be connected to a buffer tank, so that the buffer volume of raw materials can be flexibly adjusted as needed during the production process. When production demand increases, more raw materials can be temporarily stored in the buffer tank to ensure the continuity of the production process; when production demand decreases, the buffer volume can be reduced to avoid waste of raw materials. The inspection port is not only used to connect the buffer tank, but also to connect the cleaning equipment. This design makes the cleaning and maintenance of the equipment more convenient and efficient. When the equipment needs to be cleaned, the cleaning equipment can be directly connected through the inspection port to thoroughly clean the inside of the equipment, thereby extending the service life of the equipment and ensuring the sanitary quality of the product.

[0027] The utility model provides a high-efficiency separation device for the production of methoxyethyl methacrylate, which has the following beneficial effects:

[0028] The condenser group realizes efficient condensation and separation process through the reasonable layout of the conduit and reflux pipe. The conduit introduces the gaseous material into the equipment, and cools and condenses it in the reflux pipe. The cooled liquid material enters the second buffer chamber by gravity, while the incompletely condensed material circulates in the reflux pipe. This design greatly improves the separation efficiency of the material, reduces the possible loss of the material during the separation process, and ensures the high purity of the final product.

[0029] The inside of the tank is divided into different chambers by the first partition plate and the second partition plate, such as the first cache chamber, the second cache chamber and the collection chamber. This partition design not only helps the orderly progress of the separation process, but also effectively controls the flow path of the material to avoid mixing or retention of the material inside the equipment. In addition, this multi-chamber design also makes the operation of the equipment more flexible, and can make different process adjustments according to actual needs, thereby improving the adaptability of the equipment.

[0030] The inspection port on the top of the equipment is not only used to connect the buffer tank to pre-treat and buffer the raw materials, but also to connect the cleaning equipment. This design provides great convenience for cleaning and maintenance of the equipment. Especially during the production process, when the equipment needs to be cleaned regularly to ensure product quality, it can quickly connect the cleaning equipment to clean the inside, avoiding the tedious process of stopping and disassembling the traditional equipment, greatly improving the continuity of production and the service life of the equipment.

[0031] The liquid inlet and outlet are located between the two second partitions of the condenser tube group. This design can ensure the full circulation of the coolant inside the condenser tube group. Through effective cooling between the conduit and the reflux pipe, the uniformity of the liquid material during the condensation process is ensured, avoiding incomplete condensation or local overcooling. This not only improves the condensation efficiency, but also avoids energy waste, making the entire separation process more economical and efficient.

[0032] The internal space of the equipment is maximized through the reasonable design of partitions and conduits. The conduit connects the second cache chamber with the first cache chamber, and the return pipe connects the first cache chamber with the collection chamber. This structural design enables the equipment to achieve complex separation processes in a smaller volume, saving space resources. At the same time, the setting of multiple chambers allows the material to undergo different processing steps in different chambers in turn, further improving the separation efficiency and the overall performance of the equipment.

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0042] See also Figures 1 to 4 As shown, the embodiments provided by the utility model:

[0043] Embodiment 1

[0044] A high-efficiency separation device for the production of methoxyethyl methacrylate includes a tank body 1, a condenser group 2 is provided in the tank body 1, and an inspection port 103 is installed on the top of the tank body 1. The inspection port 103 is used to connect to a cache tank to further cache raw materials, or the inspection port 103 is used to connect to a cleaning device. The inspection port 103 is designed to be connected to a cache tank, so that the cache amount of raw materials can be flexibly adjusted as needed during the production process. When production demand increases, more raw materials can be temporarily stored in the cache tank to ensure the continuity of the production process; when production demand decreases, the cache amount can be reduced to avoid waste of raw materials. The inspection port 103 is not only used to connect the cache tank, but also to connect the cleaning equipment. This design makes the cleaning and maintenance of the equipment more convenient and efficient. When the equipment needs to be cleaned, the cleaning equipment can be directly connected through the inspection port 103 to thoroughly clean the inside of the equipment, thereby extending the service life of the equipment and ensuring the sanitary quality of the product. A feed port 105 is installed at the bottom end of the tank body 1, a liquid outlet 104 is installed on one side of the tank body 1, and a feed outlet 101 and a liquid inlet 102 are installed on the side of the tank body 1 away from the liquid outlet 104.

[0045] Embodiment 2

[0046] In order to increase the condensation efficiency of methoxyethyl methacrylate, exemplary, such as Figures 1 to 4As shown, the present invention also includes: the condenser tube group 2 is provided with a conduit 202, and a reflux pipe 204 is provided around the conduit 202. The raw material condensed in the reflux pipe 204 flows back to the collecting chamber 107 along the inner wall of the reflux pipe 204. Second partition plates 206 are installed at both ends of the reflux pipe 204. The liquid inlet 102 and the liquid outlet 104 are located between the two second partition plates 206 of the condenser tube group 2, which is convenient for the coolant to flow between the second partition plates 206 of the condenser tube group 2 and condense the raw material in the conduit 202 and the reflux pipe 204. The liquid inlet 102 and the liquid outlet 104 are arranged between the two second partition plates 206, which can ensure that the coolant flows evenly and fully through the condenser tube group 2 and the reflux pipe 204. This design allows the coolant to fully contact the raw materials in the conduit 202 and the reflux pipe 204, improves the heat exchange efficiency, and thus accelerates the condensation speed of the raw materials. The top of the inner part of the tank body 1 is separated into the first cache chamber 106 by the second partition plate 206 at the top of the condensing pipe group 2. The careful setting of the first cache chamber 106 allows the raw material gas or steam condensed in the conduit 202 of the condensing pipe group 2 to be further stabilized in this area. It effectively slows down the flow rate of the gas or steam, thereby significantly increasing the contact time with the coolant and greatly improving the condensation efficiency. The condensed liquid can accumulate in the first cache chamber 106 and flow smoothly into the collection chamber 107 through the reflux pipe 204. One end of the conduit 202 passes through the second partition plate 206 and is connected to the first partition plate 203. The bottom of the inner part of the tank body 1 is separated into the second cache chamber 108 by the first partition plate 203. The ingenious setting of the second cache chamber 108 allows the raw materials to be temporarily stored in this area before entering the condensing pipe group 2, thereby playing a buffering role. This helps to stabilize the supply of raw materials and reduce the impact of unstable raw material supply on the condensation and separation process. By separating the second buffer chamber 108, the rate and amount of raw materials entering the condenser tube group 2 can be more flexibly controlled, and precise adjustments can be made according to production needs to improve the controllability and stability of the production process. The collection chamber 107 is separated by the first partition plate 203 and the second partition plate 206 above the second buffer chamber 108 in the tank body 1, and the discharge port 101 is located at the collection chamber 107. The reasonable setting of the collection chamber 107 allows the methoxyethyl methacrylate after condensation and reflux to be concentrated in this area, which is convenient for subsequent collection and discharge. This design greatly simplifies the separation and collection process and significantly improves production efficiency.By separating the collection chamber 107 from the condensation tube group 2 and the second buffer chamber 108, it is possible to effectively reduce impurities and incompletely condensed gases from entering the collection chamber 107, thereby improving the purity and quality of the collected product. The second buffer chamber 108 is connected to the first buffer chamber 106 through the conduit 202, and the first buffer chamber 106 is connected to the collection chamber 107 through the reflux pipe 204. This design enables the raw material to continuously enter the first buffer chamber 106 from the second buffer chamber 108 through the conduit 202, and then enter the collection chamber 107 after the condensation and reflux process. This continuous flow path effectively guarantees the continuity and stability of the production process, and avoids the reduction of production efficiency or equipment failure caused by the interruption or accumulation of raw materials. The condensed liquid flows back to the collection chamber 107 through the reflux pipe 204, while the incompletely condensed gas may continue to circulate in the first buffer chamber 106 until it is completely condensed. This design optimizes the condensation effect, improves the condensation efficiency, and ensures the full condensation of the raw materials. By dividing the condensation and reflux processes into two independent but interconnected areas (the first buffer chamber 106 and the collection chamber 107), this design helps to improve the separation efficiency. The condensed liquid can quickly and accurately enter the collection chamber 107, reducing the residence time in the device and possible impurity mixing, thereby improving the purity and quality of the product. The outer side of the reflux pipe 204 is located between the second partition plate 206 and a support plate 201 is installed, and a through hole 205 is opened on the support plate 201.

[0047] Working principle:

[0048] The raw materials enter the device through the feed port 105 at the bottom of the tank body 1, enter the second buffer chamber 108, and enter the conduit 202 of the condenser tube group 2. The coolant enters between the conduit 202 of the condenser tube group 2 and the reflux pipe 204 through the liquid inlet 102, and is guided by the second partition plate 206 to circulate in the condenser tube group 2. These vaporized raw materials meet the coolant at the condenser tube group 2 and are quickly condensed into liquid. The condensed raw materials reflux along the inner wall of the reflux pipe 204. Due to gravity and the design of the reflux pipe 204, these raw materials eventually flow into the collection chamber 107. At the same time, the incompletely condensed gas or steam further contacts the coolant through the reflux pipe 204 to improve the condensation efficiency.

[0049] The first buffer chamber 106, the second buffer chamber 108 and the collection chamber 107 are arranged inside the device to form a multi-level buffer system. This design helps to stabilize the flow of raw materials and products, reduce fluctuations, and improve separation efficiency. The methoxyethyl methacrylate product finally separated accumulates in the collection chamber 107 and is discharged from the device through the discharge port 101.
