Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to an evaporator with an improved ejector. Background Technology

[0002] In chemical production, especially in processes involving material concentration or solvent recovery, evaporators are key core equipment. In order to improve evaporation efficiency and process heat-sensitive materials, evaporation operations are usually required under vacuum or negative pressure conditions. As a simple and reliable vacuum acquisition device, steam ejectors are widely used in systems that are matched with evaporators to extract non-condensable gases and water vapor generated during the evaporation process in order to establish and maintain a stable vacuum environment inside the evaporator.

[0003] However, actual chemical production processes are often dynamic and changing. Fluctuations in the flow rate, concentration, or temperature of upstream materials can cause changes in the working load of the evaporator, that is, changes in the amount of water vapor that needs to be removed per unit time. Such fluctuations in operating conditions pose a challenge to the stable operation of the entire evaporation system.

[0004] In the prior art, most existing steam ejectors are designed with a fixed structure. The geometric dimensions of key components such as nozzles and throats are fixed after manufacturing. This design means that the ejector can only achieve the highest pumping efficiency at a specific design point. Once the actual operating conditions deviate from this design point, such as when the amount of steam generated by the evaporator is greater or less than the design value, the performance of the fixed-structure ejector will drop sharply and it will be unable to effectively maintain the vacuum required by the system. Therefore, an improved ejector evaporator is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] An improved injector evaporator, referenced Figures 1 to 3The system includes a saponification tower 1 and an evaporator 2. The saponification tower 1 provides a stable reaction environment for the cyclization reaction. The evaporator 2 is the core equipment for wastewater vapor recovery. An adjustment mechanism 4 is installed at the right end of the evaporator 2. The adjustment mechanism 4 can precisely control the pressure of the ejector 3 to ensure stable evaporation efficiency. A quantitative feeding mechanism 5 is installed at the top of the saponification tower 1. The quantitative feeding mechanism 5 can precisely control the amount of raw materials fed to maintain reaction balance.

[0036] Specifically, the saponification tower 1 provides a key guarantee for the smooth progress of the cyclization reaction by maintaining a stable reaction environment. The evaporator 2 undertakes the function of wastewater steam recovery, realizing the efficient reuse of steam. The regulating mechanism 4 set at the right end controls the pressure of the ejector 3, thereby ensuring that the evaporation process is continuously efficient and the parameters are stable. The quantitative feeding mechanism 5 located at the top of the saponification tower 1 continuously maintains the dynamic balance of the reaction system in the tower by controlling the amount of material fed.

[0037] The regulating mechanism 4 includes a housing 41, which provides a sealed protective space for the internal components to prevent impurities from interfering with the pressure regulation accuracy. A corner block 45 is slidably connected to the inner side of the housing 41. The corner block 45 changes the channel size by sliding and engaging, thereby achieving dynamic pressure regulation. A push rod 42 is slidably connected to the inner side of the housing 41. Two inner rings 43 are fixedly connected to the outer side of the push rod 42. Multiple slide rods 44 are slidably connected to the inner side of each of the two inner rings 43. The two inner rings 43 rotate to drive the slide rods 44 to adjust their positions. The multiple slide rods 44 can convert the rotational force of the inner rings 43 into the sliding force of the corner block 45. The corner blocks 45 are fixedly connected to the outer side of each of the multiple slide rods 44. The linkage action of the corner blocks 45 can accurately change the cross-sectional area of ​​the fluid channel. The right end of the evaporator 2 is fixedly connected to the left end of the housing 41, so that the evaporator 2 and the regulating mechanism 4 form a stable whole, ensuring the immediacy of pressure regulation.

[0038] Specifically, the outer shell 41 of the regulating mechanism 4 provides a stable space for the sliding of internal components, isolates external interference to ensure the accuracy of pressure regulation, and when the push rod 42 is pushed, it drives the two inner rings 43 on the outside to rotate. The rotation of the inner rings 43 causes the multiple sliding rods 44 on the inside to slide and shift. The sliding rods 44 then drive the corner blocks 45 on the outside to slide. The right end of the evaporator 2 is fixed to the left end of the outer shell 41, so that the adjusted pressure is applied to the evaporation process immediately to ensure stable efficiency.

[0039] An ejector 3 is installed at the right end of the outer casing 41. The pressure state of the ejector 3 directly affects the wastewater evaporation efficiency. A limit component 46 is fixedly connected to the inner side of the outer casing 41. The limit component 46 can limit the range of motion of the internal components and prevent excessive displacement from affecting the adjustment effect. The limit component 46 includes multiple limit posts 462. The inner side of each limit post 462 is rotatably connected to a connecting rod 461. The outer side of each limit post 462 is fixedly connected to the inner side of the outer casing 41, providing a stable mounting point for the connecting rod 461. The connecting rod 461 can rotate flexibly with the movement of the corner block 45 to ensure the smoothness of the adjustment action. The inner side of the corner block 45 is rotatably connected to the outer side of the connecting rod 461 to ensure that the movement trajectory of the corner block 45 is accurate and controllable.

[0040] Specifically, the ejector 3 at the right end of the outer casing 41 is connected to the internal channel. Its pressure changes with the cross-sectional area of ​​the channel, directly determining the efficiency of wastewater evaporation. The limiting component 46 inside the outer casing 41 is fixed inside the casing by multiple limiting posts 462, providing a stable fulcrum for the connecting rod 461. When the corner block 45 slides, the connecting rod 461 rotates with it. The limiting posts 462 restrict the sliding range of the corner block 45, preventing abnormal channel movement due to excessive displacement. This ensures that the pressure regulation of the ejector 3 is always within the effective range, guaranteeing a stable and efficient evaporation process. The inside of the corner block 45 is rotatably connected to the connecting rod 461, and the connecting rod 461 restricts its movement trajectory, allowing the corner block 45 to precisely engage or disengage to change the cross-sectional area of ​​the channel and achieve dynamic pressure regulation.

[0041] Reference Figure 2 and Figure 4 The quantitative feeding mechanism 5 includes two liquid pipes 55. The bottom ends of the two liquid pipes 55 are fixedly connected to the inside of the saponification tower 1, providing a dedicated channel for raw material transportation and ensuring that the raw materials accurately enter the reaction area. The outer sides of the two liquid pipes 55 are fixedly connected to a fixed cylinder 53. The top of the fixed cylinder 53 is fixedly connected to a storage bin 51. The fixed cylinder 53 can fix the relative position of the liquid pipes 55 and the storage bin 51, ensuring feeding stability. The storage bin 51 can store sufficient raw materials to meet the feeding needs of continuous reaction. The inner side of the storage bin 51 is slidably connected to an inner cylinder 54. The sliding of the inner cylinder 54 can realize the quantitative interception and release of raw materials. The bottom end of the inner cylinder 54 is rotatably connected to a disc 57. The deflection of the disc 57 can control the lifting and lowering of the inner cylinder 54, thereby regulating the feeding timing.

[0042] Specifically, the bottom ends of the two liquid pipes 55 of the quantitative feeding mechanism 5 are fixed inside the saponification tower 1, which can guide the raw materials to the reaction area precisely and avoid deviation and waste during the transportation process. The fixed cylinder 53 on the outside of the liquid pipe 55 not only fixes its relative position with the storage bin 51, but also provides a stable sliding trajectory for the inner cylinder 54. The storage bin 51 stores enough raw materials to meet the feeding needs of continuous reaction. The inner cylinder 54 on its inner side can slide up and down with the deflection of the disc 57. When the disc 57 rotates, it drives the inner cylinder 54 to adjust its height. When the inner cylinder 54 is precisely aligned with the liquid pipe 55, the raw material is released. Through this set of linkage actions, the timing and amount of feeding are precisely controlled to ensure the stable progress of the reaction.

[0043] A liquid pipe 55 is installed at the bottom of the storage bin 51. The liquid pipe 55 can guide the raw material to flow in a specific direction and avoid leakage and waste. A metering cylinder 52 is fixedly connected to the top of the inner cylinder 54. The volume of the metering cylinder 52 is fixed, which can ensure that the amount of material fed each time is accurate and consistent. The bottom of the metering cylinder 52 is in contact with the inner side of the storage bin 51 to form a sealing structure and prevent the raw material from leaking out in advance. The outer side of the inner cylinder 54 is in contact with one end of the liquid pipe 55 to ensure the sealing and alignment accuracy during the material conveying. A spring 58 is fixedly connected to the bottom of the fixed cylinder 53. The spring 58 can quickly push the inner cylinder 54 to reset, improving the feeding cycle efficiency. The bottom of the spring 58 is fixedly connected to the top of the inner cylinder 54, so that the reset force acts directly on the inner cylinder 54 to ensure sensitive action. A motor 56 is installed at the bottom of the storage bin 51. The motor 56 can provide stable driving force to ensure the accuracy of the rotation of the disc 57. The drive end of the motor 56 is fixedly connected to the inside of the disc 57 to enable efficient transmission of driving force and achieve precise control of feeding action.

[0044] Specifically, the liquid pipe 55 at the bottom of the storage silo 51 is precisely connected to the inner cylinder 54 and the saponification tower 1. This not only guides the directional flow of raw materials to avoid leakage, but also allows for rapid material delivery when aligned with the inner cylinder 54. The metering cylinder 52 at the top of the inner cylinder 54, with its fixed volume, can accurately dispense a fixed amount of raw material each time. Its bottom end is in close contact with the inner side of the storage silo 51 to form a seal, preventing premature leakage of raw materials from the source. The outer side of the inner cylinder 54 is fitted with one end of the liquid pipe 55, ensuring both sealing during delivery and precise alignment to prevent material delivery deviation. The spring 58 at the bottom of the fixed cylinder 53 is directly connected to the top of the inner cylinder 54. After the material is fed, it can quickly release the spring force to push the inner cylinder 54 to reset, saving time for the next feeding cycle and greatly improving work efficiency. The motor 56 at the bottom of the storage bin 51 provides stable driving force. Its drive end is fixedly connected to the disc 57, which can efficiently transmit power to the disc 57, drive the disc 57 to deflect precisely, and then control the lifting height of the inner cylinder 54, so as to achieve dual precise control of the feeding timing and quantity, and provide a stable supply guarantee for the cyclization reaction in the saponification tower 1.

[0045] The implementation principle of this application embodiment is as follows: When it is necessary to adjust the working efficiency of the evaporator 2, the operator pushes the push rod 42 of the adjustment mechanism 4. The push rod 42 drives the inner ring 43 to rotate. The rotation of the inner ring 43 causes the slide rod 44 in its slide groove to move, thereby driving multiple corner blocks 45 to simultaneously achieve radial contraction or expansion. Since the corner blocks 45 directly act on the key internal parts of the ejector 3, their position change changes the cross-sectional area of ​​the steam or fluid channel, thereby accurately adjusting the working pressure and pumping performance of the ejector 3 to match the current working conditions, so as to optimize the steam recovery efficiency, stabilize the wastewater temperature and reduce energy consumption. During the entire adjustment process, the limiting component 46 ensures the smooth and precise movement of the corner blocks 45 through the constraint of the connecting rod 461 and the limiting column 462.

[0046] When materials need to be added to the saponification tower 1, the motor 56 of the quantitative feeding mechanism 5 starts, driving the disc 57 to rotate. The eccentric structure of the disc 57 converts the rotational motion into the linear reciprocating motion of the inner cylinder 54 within the fixed cylinder 53. The inner cylinder 54 first moves upward to the upper stroke, and the quantitative cylinder 52 at its top extends into the storage bin 51 and automatically fills it with a predetermined volume of material. Subsequently, the inner cylinder 54 slides downward, and when the first through hole on its side wall aligns with the second through hole on the side wall of the fixed cylinder 53, the material in the quantitative cylinder 52 flows into the saponification tower 1 through the connected channels and liquid pipe 55 under the action of gravity, completing one precise quantitative feeding. After feeding, with the assistance of the spring force of the spring 58, the inner cylinder 54 quickly returns to its initial position, ready for the next cycle. Through this automated, volumetric quantitative feeding, the stability and accuracy of the saponification reaction ratio are ensured, thereby effectively reducing the organic matter content in the wastewater.
