Description

Technical Field

[0001] This invention relates to the field of epichlorohydrin purification technology, specifically to a water-vapor high-efficiency epichlorohydrin purification device. Background Technology

[0002] Epichlorohydrin (ECH), chemically known as 1-chloro-2,3-epoxypropane, is a volatile, unstable, colorless, oily liquid with an irritating odor similar to chloroform and ether. It is toxic and has anesthetic properties. Its density is 1.18 g / cm³, and its boiling point is 115.2℃. It is slightly soluble in water and miscible with many organic solvents; its solubility in water at 20℃ is 6.6% (mass fraction). It can form azeotropes with many organic liquids. The epichlorohydrin molecule contains epoxy groups and chlorine. Under alkaline conditions, it hydrolyzes to glycerol; it reacts with hydroxyl-containing organic compounds, such as alcohols and phenols, to form ring-opening ether compounds; and it reacts with bisphenol A to form epoxy resins. Therefore, epichlorohydrin is an important raw material for the production of epoxy resins, the synthesis of glycerol, and chlorohydrin rubber. It can also be used to prepare other derivatives and as a solvent, plasticizer, flame retardant, and surfactant, exhibiting a wide range of applications.

[0003] The high-temperature chlorination of propylene is a classic industrial method for producing epichlorohydrin, and currently, more than 90% of epichlorohydrin worldwide is produced using this method. The process mainly involves three reaction units: high-temperature chlorination of propylene to produce allyl chloride, reaction of allyl chloride with hypochlorous acid to synthesize dichloropropanol, and cyclization of dichloropropanol to synthesize epichlorohydrin.

[0004] Currently, the water vapor separation and epichlorohydrin purification equipment on the market has a low yield due to the production of by-products during the production process. Changing the temperature and pressure of the raw materials dichloropropanol and lime milk before they enter the cyclization tower can improve the reaction yield, which means that the efficiency of the processing process needs to be improved. Therefore, an improved equipment is needed to address the above problems. Summary of the Invention

The upper part of the displacement slider is slidably connected to the adapter track frame. The adapter track frame is internally connected to the connecting seat.

[0009] Specifically, the heating structure includes a limiting frame, a first regulating component, a stabilizing connecting seat, and a supporting base plate. Stabilizing connecting seats are fixedly connected to both the left and right sides of the supporting base plate. The limiting frame is fixedly connected to the center of the supporting base plate, and the center of the limiting frame is slidably connected to the first regulating component.

[0010] Specifically, the heating structure further includes a second regulating component, and the first regulating component is fixedly connected to the second regulating component.

[0011] Specifically, the second control component includes a first displacement plate frame, a first heater, a first toothed plate, a drive toothed disc, a second toothed plate, a second displacement plate frame, and a second heater.

The pressurization structure is connected to the first connecting pipe through the guide pipe.

[0013] Specifically, the dual-head motor is connected to the displacement slider via a second hinge rod, a first hinge rod, and a matching wheel, allowing it to slide within the adaptable track frame.

[0014] Specifically, a first support plate is fixedly connected to the upper end of the limiting frame, and a second support plate is fixedly connected to the front end of the first support plate.

[0015] A method for using a high-efficiency water vapor separation and epichlorohydrin purification device includes the following steps:

[0016] S1. First, lime slurry is introduced through the first connecting pipe. Then, the lime slurry can be further conducted through the second connecting pipe. Through the connection of the connecting pipe and the connecting tube, it can be connected to the external reaction structure. When the lime slurry is conducted, the user can drive the pressurization structure to work. The double-headed motor drives the second hinge rod to rotate. At the same time, the second hinge rod drives the first hinge rod to rotate.

[0017] S2. After that, the first hinge rod can drive the mating wheel to rotate, which acts on the displacement slider, so that the displacement slider slides in the adapter track frame, thereby realizing the compression of the connecting seat. The gas is conducted to the inside of the first connecting pipe through the guide pipe, realizing the pressurization of the first connecting pipe. Then, the lime milk can be transferred to the position of the second connecting pipe through pressurization.

[0018] S3. Finally, the drive wheel can be driven to rotate, and the drive wheel is connected to the drive belt to achieve synchronous rotation, which can drive the drive gear to rotate. The rotation of the drive gear can synchronously drive the first gear plate and the second gear plate to move, so that the first displacement plate frame drives the first heater to move, and the second displacement plate frame drives the second heater to move, thereby changing the contact distance between the first heater and the second heater and the second connecting pipe, thus realizing contact control operation.

[0019] The beneficial effects of this invention are:

[0020] First, this invention utilizes a pressurization structure to regulate the compression process. An air guide pipe and air pump introduce airflow, and a dual-head motor drives the second and first hinge rods and the cooperating wheel to move, causing the displacement slider to slide within the adaptable track frame. Simultaneously, this achieves internal compression of the connecting seat, allowing airflow to be guided through the guide pipe to the first connecting pipe location, thus achieving highly efficient pressurization and improving the efficiency of the purification reaction.

[0021] Second, the present invention performs contact heating regulation by setting the second regulating component. The transmission wheel can drive the drive toothed disc to rotate, which acts on the first toothed plate and the second toothed plate, so that the first displacement plate frame drives the first heater to move, and at the same time, the second displacement plate frame drives the second heater to move, thereby realizing the contact between the first heater, the second heater and the second connecting pipe, thereby realizing the temperature control inside the second connecting pipe.

[0044] The first heater 24 and the second heater 29 are fitted and connected to the second connecting pipe 3. The first connecting pipe 2, the second connecting pipe 3, the connecting pipe 4, and the mating pipe 5 are connected and arranged in a continuous manner.

Through the arrangement of the structure, it is convenient to perform combination and connection work, which is more conducive to the cooperation between the structures.

[0045] A method for using a high-efficiency water vapor separation and epichlorohydrin purification device includes the following steps:

[0046] S1. First, lime slurry is introduced through the first connecting pipe 2. Then, the lime slurry can be further conducted through the second connecting pipe 3. Through the connection of the connecting pipe 4 and the cooperating pipe 5, it can be connected to the external reaction structure. During the conduction of lime slurry, the user can drive the pressurizing structure 1 to work. The double-headed motor 11 drives the second hinge rod 17 to rotate. At the same time, the second hinge rod 17 drives the first hinge rod 16, which is hinged, to rotate.

[0047] S2. Then, the first hinge rod 16 can drive the mating wheel 14 to rotate, which acts on the displacement slider 13, so that the displacement slider 13 slides in the adapter track frame 15, thereby realizing the compression of the connecting seat 9. The gas is conducted to the inside of the first connecting pipe 2 through the guide pipe 10, realizing the pressurization of the first connecting pipe 2. Then, the lime milk can be transferred to the position of the second connecting pipe 3 through pressurization. At this time, the first heater 24 and the second heater 29 can work to achieve the heating purpose of the second connecting pipe 3 and improve the reaction efficiency.

[0048] S3. Finally, the drive wheel 30 can be driven to rotate, and the drive wheel 30 is connected to the drive belt 31 to achieve synchronous rotation, thereby driving the drive gear 26 to rotate. The rotation of the drive gear 26 can synchronously drive the first gear plate 25 and the second gear plate 27 to move, so that the first displacement plate frame 23 drives the first heater 24 to move, and the second displacement plate frame 28 drives the second heater 29 to move, thereby changing the contact distance between the first heater 24 and the second heater 29 and the second connecting pipe 3, thereby realizing contact-type control operation.

[0049] The working principle of Example 1 is as follows: In use, the pressurizing structure 1, the first connecting pipe 2, the second connecting pipe 3, the connecting tube 4, the fitting pipe 5, and the heating structure 6 are combined and connected. Lime slurry is introduced through the first connecting pipe 2, and then the lime slurry can be further conducted through the second connecting pipe 3. Through the connection of the connecting tube 4 and the fitting pipe 5, it can be connected to the external reaction structure. During lime slurry conduction, the user can drive the pressurizing structure 1 to work. Driven by the double-headed motor 11, the second hinge rod 17 rotates. Simultaneously, the second hinge rod 17, through its drive, drives the hinged first hinge rod 16 to rotate. The first hinge rod 16 then drives the fitting wheel 14 to rotate, acting on the displacement slider 13, causing the displacement slider 13 to slide within the adaptable track frame 15, thereby achieving the compression of the connecting seat 9. Gas is conducted through the guide pipe 10 to the first... Inside the first connecting pipe 2, pressurization is achieved. The lime slurry is then transferred to the second connecting pipe 3 under pressure. At this point, the first heater 24 and the second heater 29 can operate, heating the second connecting pipe 3 and improving reaction efficiency. When temperature control is required, the transmission wheel 30 can be driven to rotate. The transmission wheel 30 is connected via a transmission link 31 to achieve synchronous rotation, which in turn drives the drive toothed disc 26 to rotate. The rotation of the drive toothed disc 26 synchronously drives the first toothed plate 25 and the second toothed plate 27 to move, causing the first displacement plate 23 to drive the first heater 24 to move, and the second displacement plate 28 to drive the second heater 29 to move. This changes the contact distance between the first heater 24 and the second heater 29 and the second connecting pipe 3, achieving contact-type temperature control.
