Description

Technical Field

[0001] This invention relates to the field of chemical condensation equipment technology, specifically to a condensation device for butyl acetate. Background Technology

[0002] Butyl acetate, as an excellent organic solvent, extractant, and fragrance raw material, is widely used in industries such as coatings, pharmaceuticals, fragrances, and adhesives. During its production (esterification reaction of n-butanol and acetate), distillation purification, and waste liquid recovery, a large amount of butyl acetate vapor is generated. It needs to be efficiently liquefied and recovered through condensation equipment to reduce material loss and environmental pollution.

[0003] Existing butyl acetate condensation equipment mostly uses conventional shell-and-tube condensers and tubular condensers, which have many technical defects in practical applications: First, the condensation method is singular, and condensation is completed only through a single cooling water heat exchange, resulting in the direct discharge of incompletely condensed steam, low condensation recovery rate, and serious material loss; Second, the heat exchange efficiency is low, the contact area between steam and cooling medium is small, the heat exchange rate is slow, a large amount of cooling water is required, and the energy consumption is high; Third, the equipment has a large power consumption, and long-term operation will lead to a continuous decline in condensation efficiency, increasing equipment operation and maintenance costs.

[0004] To address the aforementioned issues, while some existing condensers have undergone structural improvements, most only optimize for a single defect and cannot simultaneously achieve a comprehensive effect of high condensing efficiency, low energy consumption, and easy maintenance. Therefore, developing a dedicated condensing device that is adapted to the properties of butyl acetate, has high condensing efficiency, low energy consumption, and is easy to maintain has become a pressing technical problem for those skilled in the art.

[0008] Preferably, the pressurizing component includes a bottom frame fixedly connected to the upper surface of the base plate. A dual-head motor is disposed inside the bottom frame. The output end of the dual-head motor is connected to a first turntable via a coupling. A first connecting rod is rotatably connected to the outer side of the outer surface of the first turntable. A first slider is rotatably connected to the upper end of the first connecting rod. A guide rod is fixedly connected to the upper surface of the first slider. The upper end of the guide rod is connected to the flow guiding component.

[0009] Preferably, the flow guiding assembly includes a flow guiding cylinder, inside which a piston is fixedly connected to a guide rod is disposed, the piston is slidably connected to the inner wall of the flow guiding cylinder, and the upper end of the flow guiding cylinder is connected through a flow guiding pipe, the flow guiding pipe being a one-way pipe and communicating with a cooling box.

[0010] Preferably, the heat dissipation assembly includes a base fixedly connected to the upper surface of the base plate. The base has a transmission rod fixedly connected to the output end of the dual-head motor. A first bevel gear is fixedly connected to the outer wall of the transmission rod and located inside the base. A second bevel gear is meshed with the side wall of the first bevel gear. A first drive rod is fixedly connected to the middle of the second bevel gear. The upper end of the first drive rod is connected to a second drive rod through a speed increaser. A fan blade is fixedly connected to the outer wall of the upper end of the second drive rod. A protective cover is provided on the outer side of the fan blade.

[0011] Preferably, the vibration assembly includes a connecting frame fixedly connected to the upper surface of the base plate. Inside the connecting frame, a second turntable is fixedly connected to the transmission rod. A second connecting rod is rotatably connected to the outer side of the outer surface of the second turntable. A second slider is rotatably connected to the upper end of the second connecting rod. A top rod is fixedly connected to the upper surface of the second slider. The upper end of the top rod is connected to an elastic head.

The cold end of the refrigeration plate is in contact with the cooling box, and the hot end of the refrigeration plate faces outward.

[0014] (III) Beneficial Effects This invention provides a condensation device for butyl acetate, which has the following advantages: 1. This invention, by setting an inclined condenser tube in conjunction with a heat-conducting tube sleeved on the outer wall, utilizes a pressurizing component to drive a flow guiding component to achieve the circulation of the cooling medium between the heat-conducting tube and the cooling box. This allows for continuous heat exchange and condensation of butyl acetate vapor in the condenser tube. Compared to traditional fixed-flow-rate cooling water heat exchange, the circulation flow rate can be adjusted according to condensation requirements, improving heat exchange efficiency. Simultaneously, the pressurizing component can drive the heat dissipation component to perform air cooling heat dissipation on the cooling box, accelerating the temperature drop of the cooling medium in the cooling box. No additional power components are needed to drive the heat dissipation, reducing the overall energy consumption of the equipment and avoiding the problem of decreased condensation efficiency due to the temperature rise of the cooling medium after long-term heat exchange.

[0015] 2. This invention synchronously drives the vibration component through the power output of the pressurizing component, causing the elastic head to continuously vibrate and strike the condenser tube. This prevents liquefied butyl acetate from adhering to the inner wall of the condenser tube during the condensation process, ensuring the heat exchange effect of the inner wall of the condenser tube. At the same time, the staggered heat-conducting plates and through holes can extend the residence time of butyl acetate vapor in the condenser tube, increase the contact area between the vapor and the condenser tube wall, further improve the condensation efficiency, ensure that the incompletely liquefied vapor can also be fully heat-exchanged, improve the recovery rate of butyl acetate, and reduce material loss and environmental pollution.

[0016] 3. This invention provides power for three working processes—flow circulation, heat dissipation and cooling, and pipe wall desorption—simultaneously through a dual-head motor. Compared with the traditional structure driven by multiple separate motors, this simplifies the equipment structure, reduces the overall power consumption and maintenance costs, and achieves the effect of single-power-driven multi-process collaborative operation. It is suitable for the working requirements of butyl acetate vapor condensation and has better overall performance. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: like Figure 1 As shown, this embodiment of the invention provides a condensation device for butyl acetate, including a base plate 1. A housing 2 is fixedly connected to the upper end of the base plate 1. An inclined condenser pipe 3 is arranged on the inner wall of the housing 2, with an inclination angle of 5-15°. A heat-conducting pipe 4 is sleeved on the outer wall of the condenser pipe 3. A cooling box 5 is arranged on the right side of the housing 2. The bottom end of the cooling box 5 is connected to a unidirectional flow inlet pipe 6 via a flow guide assembly 8. The other end of the inlet pipe 6 is connected to the bottom of the heat-conducting pipe 4. A return pipe 7 is also connected to the upper side of the heat-conducting pipe 4, and the other end of the return pipe 7 is connected to the upper side of the cooling box 5. A vent pipe 13 is connected to the left end of the condenser pipe 3 for the introduction of butyl acetate vapor. A drain pipe 14 is connected to the right end of the condenser pipe 3, extending to the outside of the housing 2. A temperature control valve 15 is installed at its outer end to control the flow state according to the temperature of the discharged liquid, preventing insufficiently condensed vapor from being directly discharged. The outer wall of the cooling box 5 is provided with several fins 16, and a cooling plate 17 is also provided on the right side of the cooling box 5. The cold end of the cooling plate 17 is in contact with the cooling box 5, and the hot end of the cooling plate 17 faces outward, which further helps the cooling medium in the cooling box 5 to maintain a low temperature and improve the stability of continuous heat exchange.

[0021] The above structure allows the cooling medium to circulate continuously between the cooling box 5 and the heat pipe 4, using the cooling medium to remove the heat from the outer wall of the condenser 3, thereby achieving continuous heat exchange of butyl acetate vapor inside the condenser 3.

[0022] Secondly, such as Figure 2 and Figure 3 As shown, the inner wall of the condenser tube 3 is provided with several heat-conducting plates 31 arranged axially. The heat-conducting plates 31 are staggered, and several through holes 32 are opened in the middle of the heat-conducting plates 31. The inclined condenser tube 3 facilitates the flow out of liquefied butyl acetate by gravity, eliminating the need for an additional pumping structure and further reducing equipment energy consumption. The staggered arrangement of the heat-conducting plates 31 extends the steam residence time and increases the contact area without excessively increasing the steam flow resistance, ensuring stable pressure at the equipment inlet and smoother operation.

[0023] like Figure 1 and Figure 4 As shown, a pressurizing component 9 is also provided on the upper side of the base plate 1. The pressurizing end of the pressurizing component 9 is connected to the flow guiding component 8. The pressurizing component 9 can drive the flow guiding component 8 to continuously pump the cooling medium and adjust the circulation flow to adapt to different condensation loads. Specifically, the pressurizing component 9 includes a bottom frame 91 fixedly connected to the upper surface of the base plate 1. A dual-head motor 92 is provided inside the bottom frame 91. The output end of the dual-head motor 92 is connected to a first turntable 93 through a coupling. A first connecting rod 94 is rotatably connected to the outer side of the outer surface of the first turntable 93. A first slider 95 is rotatably connected to the upper end of the first connecting rod 94. A guide rod 96 is fixedly connected to the upper surface of the first slider 95. The upper end of the guide rod 96 is connected to the flow guiding component 8.

[0024] The above structure, through the dual-head motor 92 driving the first turntable 93 to rotate, together with the first connecting rod 94, can drive the first slider 95 and the guide rod 96 to perform reciprocating lifting and lowering motion, providing stable pumping power for the flow guiding assembly 8.

[0025] Secondly, the flow guiding assembly 8 includes a flow guiding cylinder 81. Inside the flow guiding cylinder 81, there is a piston 82 that is fixedly connected to the guide rod 96. The piston 82 is slidably connected to the inner wall of the flow guiding cylinder 81. The upper end of the flow guiding cylinder 81 is connected to a flow guiding pipe 83. The flow guiding pipe 83 is a one-way pipe and is connected to the cooling box 5. With the help of the one-way inlet pipe 6, the one-way stable circulation of the cooling medium can be realized. The structure is simple and reliable and the maintenance difficulty is low.

[0026] The above structure continuously pumps the cooling medium in the cooling box 5 into the heat pipe 4 by driving the piston 82 to reciprocate through the guide rod 96, thereby realizing the circulation and heat exchange of the cooling medium. The unidirectional pipeline design avoids the backflow of the medium and ensures the stability of the circulation flow.

[0027] like Figure 1 and Figure 5 As shown, the output end of the pressurizing component 9 is also connected to the heat dissipation component 10. The air blowing end of the heat dissipation component 10 is accelerated and blown towards the cooling box 5, which can remove the heat from the outer wall of the cooling box 5 and accelerate the cooling of the cooling medium. Specifically, the heat dissipation component 10 includes a base 101 fixedly connected to the upper surface of the base plate 1. The base 101 is provided with a transmission rod 102 fixedly connected to the output end of the dual-head motor 92. The outer wall of the transmission rod 102 and located inside the base 101 is fixedly connected to a first bevel gear 103. The side wall of the first bevel gear 103 is meshed with a second bevel gear 104. The middle part of the second bevel gear 104 is fixedly connected to a first drive rod 105. The upper end of the first drive rod 105 is connected to a second drive rod 107 through a speed increaser 106. The upper outer wall of the second drive rod 107 is fixedly connected to a fan blade 108. The outer side of the fan blade 108 is provided with a protective cover 109 for dust prevention and protection.

[0028] The above structure uses the power output of the dual-head motor 92 to drive the transmission rod 102 to rotate, and with the bevel gear transmission and speed increaser 106, it can drive the fan blade 108 to rotate at high speed to generate a stable airflow to cool the cooling box 5. No additional power components are needed, which reduces the overall energy consumption of the equipment.

[0029] like Figure 1 and Figure 6 As shown, the output end of the pressurizing component 9 is also connected to a vibration component 11. The vibration end of the vibration component 11 is connected to an elastic head 12 that acts on the bottom of the condenser tube 3. Continuous vibration can prevent liquefied butyl acetate from adhering to the inner wall of the condenser tube 3, thus ensuring heat exchange efficiency. Specifically, the vibration component 11 includes a connecting frame 111 fixedly connected to the upper surface of the base plate 1. Inside the connecting frame 111, a second turntable 112 is fixedly connected to the transmission rod 102. The outer surface of the second turntable 112 is rotatably connected to a second connecting rod 113. The upper end of the second connecting rod 113 is rotatably connected to a second slider 114. The second slider 114 is slidably connected to the inner wall of the connecting frame 111. The upper surface of the second slider 114 is fixedly connected to a top rod 115, and the upper end of the top rod 115 is connected to the elastic head 12.

[0030] The above structure drives the second turntable 112 to rotate via the transmission rod 102. In conjunction with the second connecting rod 113, it drives the second slider 114, the push rod 115, and the elastic head 12 to perform reciprocating lifting and lowering motion. This causes the elastic head 12 to continuously strike the bottom of the condenser tube 3. The vibration causes the liquid butyl acetate adhering to the inner wall of the condenser tube 3 to fall off and flow out along the inclined tube wall. This ensures that the heat exchange performance of the condenser tube 3 is not affected by the accumulation of liquid. The structure is simple and relies on the output power of the dual-head motor 92, so no additional drive components are required.

[0031] Working principle: In actual operation, butyl acetate vapor enters the inclined condenser 3 through the vent pipe 13. Starting the dual-head motor 92 sequentially drives the flow circulation, heat dissipation, and vibration desorption operations: the output of the dual-head motor 92 drives the first turntable 93 to rotate. The first turntable 93, through the first connecting rod 94, drives the first slider 95 and the guide rod 96 to reciprocate up and down, thereby driving the piston 82 to slide back and forth inside the guide tube 81. Combined with the unidirectional guide tube 83, this continuously pressurizes and sends the cooling medium in the cooling box 5 into the heat-conducting... Inside tube 4, as the cooling medium flows within the heat pipe 4, it absorbs heat from the butyl acetate vapor through the wall of the condenser tube 3. After heat exchange, the cooling medium flows back to the cooling box 5 via the return pipe 7, achieving the recycling of the cooling medium. Simultaneously, the output end of the dual-head motor 92 drives the transmission rod 102 to rotate. The transmission rod 102 drives the first drive rod 105 to rotate via the first bevel gear 103 and the second bevel gear 104. After being accelerated by the speed increaser 106, it drives the second drive rod 107 and the fan blade 108 to rotate at high speed, moving towards... The cooling box 5 blows out a high-speed airflow, which, together with the fins 16 on the outer wall of the cooling box 5, accelerates the heat dissipation of the cooling medium. At the same time, the cooling plate 17 can assist in further cooling the cooling box 5, ensuring that the cooling medium always maintains a low temperature and maintains stable heat exchange efficiency. During the rotation of the transmission rod 102, it also drives the second turntable 112 to rotate simultaneously. The second turntable 112 drives the second slider 114 and the top rod 115 to perform reciprocating lifting and lowering motion through the second connecting rod 113. The elastic head 12 repeatedly taps and vibrates the condenser tube 3, causing the condensed material to adhere to the condenser tube 3. Liquid butyl acetate on the inner wall slides down and is discharged from the drain pipe 14 along the inclined condenser pipe 3. The temperature control valve 15 can control the flow state according to the temperature of the discharged liquid to prevent insufficiently condensed vapor from being discharged directly and to ensure the recovery effect. When butyl acetate vapor flows in the condenser pipe 3, the staggered heat-conducting plates 31, together with the through holes 32 on the heat-conducting plates 31, can prolong the residence time of the vapor and increase the contact area between the vapor and the inner wall of the condenser pipe 3, further improving the heat exchange and condensation effect and ensuring that most of the butyl acetate vapor can be liquefied and recovered.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
