Description

Technical Field

[0001] This utility model belongs to the field of vaporizer technology, and in particular relates to a vertical vaporizer that facilitates char removal. Background Technology

[0002] When 2-methylpyridine feedstock is vaporized into gas using a vaporizer, the feedstock decomposes under high temperature conditions, generating some low molecular weight organic compounds. These compounds may further react to form high molecular weight polymers, which are in char or solid form and eventually deposit inside the vaporizer to form char.

[0003] Existing vaporizers typically heat and vaporize 2-methylpyridine feedstock through a coil located inside the vaporization chamber. The coke formed by the vaporization of 2-methylpyridine feedstock adheres to the inner wall of the coil and the vaporization chamber. Due to the complex structure of the coil itself and the space it occupies inside the vaporization chamber, cleaning the coke is extremely difficult.

[0004] Therefore, it is necessary to improve the vaporizers in the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a vertical vaporizer that facilitates decoking, thereby improving the ease of cleaning the coke inside the vaporizer.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the vertical vaporizer and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] like Figure 1 , 4 As shown in Figures 5 and 6, a vertical vaporizer for easy decoking includes a housing 1 and a door 102 disposed on the housing 1. An air outlet 101 is provided on the top of the housing 1. A raw material basin 6 is disposed inside the housing 1. A heater 7 is disposed on the outer wall of the raw material basin 6. The raw material basin 6 is enclosed inside a protective bag 3. The bag wall of the protective bag 3 is attached to the inner wall of the raw material basin 6.

[0027] The vaporizer described above is applicable to, but not limited to, the vaporization of 2-methylpyridine raw material. The raw material basin 6 is made of stainless steel and its surface is polished smooth to prevent damage to the protective bag 3. The heater 7 is an electric heating wire, which is evenly distributed on the bottom outer wall of the raw material basin 6. The protective bag 3 seals both the raw material basin 6 and the heater 7 inside, thereby achieving isolation between the raw material basin 6 and the raw material.

[0028] The specific working process is as follows: the raw material is injected into the raw material basin 6 and heated by the heater 7 to vaporize it. The vaporized raw material is discharged from the air outlet 101. During the vaporization process, the charred residue produced remains inside the raw material basin 6. Under the isolation effect of the protective bag 3, the charred residue adheres to the protective bag 3. After a period of use, when the amount of charred residue reaches a certain level, the vaporizer can be stopped, the door 102 can be opened, and the protective bag 3 covering the raw material basin 6 can be replaced to complete the cleaning of the charred residue, greatly improving the convenience and efficiency of cleaning.

[0029] In this vaporizer, the protective bag 3 is made of polytetrafluoroethylene (PTFE) film. PTFE film possesses excellent corrosion resistance and self-lubricating properties, can withstand the corrosion of 2-methylpyridine raw material, and reduces the adhesion of charred material to the surface of the protective bag 3, facilitating subsequent processing and recycling. During vaporization, the vaporization temperature of 2-methylpyridine raw material is 204 degrees Celsius, while PTFE film exhibits excellent high-temperature resistance, with a long-term operating temperature up to 260 degrees Celsius and a short-term operating temperature up to 300 degrees Celsius, effectively withstanding the high temperatures during raw material vaporization.

[0030] The protective bag 3 not only improves the convenience and efficiency of cleaning coke, but also protects the raw material basin 6 and heater 7, extending their service life and reducing equipment maintenance costs. Furthermore, the bag-like structure of the protective bag 3 allows the inside and outside of the bag to be flipped over when it is removed, thus wrapping the coke inside the bag and preventing it from dripping and contaminating other parts of the vaporizer.

[0031] Further improvements include, for example Figure 1 As shown, multiple raw material basins 6 are provided, and each raw material basin 6 is arranged at equal intervals along the vertical direction. The housing 1 is equipped with a feeding mechanism. The arrangement of multiple raw material basins 6 allows for the simultaneous heating and vaporization of a larger quantity of raw materials, thereby improving the working efficiency of the vaporizer.

[0032] Further improvements include, for example Figure 1 , 2 As shown in Figure 6, the box door 102 is located on the side of the box body 1, and the raw material basin 6 is detachably connected to the box body 1; the inner wall of the box body 1 is fixedly connected to the plug-in seat 103, the plug-in seat 103 is plugged into and fitted with the plug-in sleeve 602, the plug-in sleeve 602 is fixedly connected to the raw material basin 6, and the plug-in sleeve 602 is threadedly connected with a locking element. In this vaporizer, the connector 103 is a long, flat structure, horizontally positioned, and its extension direction is aligned with the opening of the housing 1. The locking element is a handle screw 8, threaded onto the connector sleeve 602. When assembling or disassembling the raw material container 6, the connector 103 and connector sleeve 602 can be locked and unlocked by turning the handle screw 8. When unlocked, the raw material container 6 can be removed from the connector 103. During installation, simply align the connector 103 and connector sleeve 602, and then place the connector sleeve 602 onto the connector 103. The flat, strip-shaped structure of the connector 103, in conjunction with the connector sleeve 602, restricts the rotation of the connector sleeve 602, thereby improving the stability of the raw material container 6 during installation. The extension direction of the connector 103 guides the raw material container 6 to slide directly opposite the opening of the housing 1 during assembly or disassembly, facilitating the assembly or disassembly of the raw material container 6.

[0033] Further improvements include, for example Figure 4 As shown, the protective bag 3 has a circumferentially elastic closing ring 301 at its opening. The closing ring 301 can be made of silicone rubber. Due to the excellent high-temperature resistance of silicone rubber, the closing ring 301 can withstand the temperature inside the vaporizer. The closing ring 301 allows the opening of the protective bag 3 to automatically shrink, thereby creating a self-sealing effect and ensuring that the protective bag 3 has a certain sealing effect.

[0034] A further improvement is that the protective bag 3 has a sealed wrapping around the sealing ring 301. After the protective bag 3 has the sealing ring 301 wrapped around its wall, it can protect the sealing ring 301, reduce the corrosion of the sealing ring 301, ensure its good elasticity, and thus extend the service life of the protective bag 3.

[0035] Further improvements include, for example Figure 4-6 As shown, a through hole 601 is provided on the bottom wall of the raw material basin 6. When the raw material is injected into the raw material basin 6, the raw material squeezes the bag wall of the protective bag 3, making it fit tightly against the inner wall of the raw material basin 6. The through hole 601 facilitates the discharge of air between the protective bag 3 and the inner wall of the raw material basin 6, thereby ensuring the fit between the two and ultimately ensuring that the raw material basin 6 has a large volume to hold more raw materials.

[0036] Further improvements include, for example Figure 3 As shown, the feeding mechanism includes feeding pipes 2 respectively located directly above each raw material container 6. Each feeding pipe 2 has an opening 201. One end of the feeding pipe 2 extends to the outside of the housing 1 and is connected to a raw material container 4. A power pump 5 is installed on the feeding pipe 2. In this vaporizer, the power pump 5 drives the raw materials inside the raw material container 4 to be transported through the feeding pipes 2 to the opening 201, and then replenished into the raw material container 6 from the opening 201, thereby achieving automatic replenishment of raw materials and improving the working efficiency and convenience of the vaporizer. Each feeding pipe 2 is equipped with an independent power pump, allowing for independent replenishment of raw materials to each raw material container 6. The replenishment rate of the raw materials can be set according to the vaporization rate of the raw materials, which can be observed through a transparent observation window on the housing or door.
