Description

Technical Field

[0001] This utility model belongs to the field of vaporizer technology, and in particular relates to a vertical vaporizer with good defoaming effect. Background Technology

[0002] When using a vaporizer to vaporize 2-cyanopyridine raw material, the raw material needs to be rapidly heated to boil. This results in liquid droplets being carried in the generated gas. The liquid droplets mixed in the gas can corrode subsequent equipment and introduce impurities, affecting product quality.

[0003] Existing technologies typically use Pall rings to eliminate liquid droplets, but due to the relatively regular shape of the Pall rings, their ability to capture liquid droplets in complex flow conditions is limited. In some turbulent airflow situations, liquid droplets cannot be effectively guided to the packing surface, but instead bypass the Pall rings under the influence of the airflow, reducing the demisting effect.

[0004] Therefore, it is necessary to improve the existing vertical vaporizer. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a vertical vaporizer with good defoaming effect, thereby improving the defoaming effect of the vertical vaporizer.

[0006] To achieve the above objectives, the specific technical solution of the vertical vaporizer with good defoaming effect of this utility model is as follows:

[0007] A vertical vaporizer with good defoaming effect includes a vaporizer body with an air outlet at the top, a defoaming box connected to the air outlet, a plurality of wire mesh defoaming discs stacked inside the defoaming box, and a drive mechanism for driving the wire mesh defoaming discs to rotate on the defoaming box.

[0008] Preferably, the demister includes a box body with a lid on the top, an air inlet pipe at the bottom of the box body communicating with the air outlet, and an exhaust pipe on the lid.

[0009] Preferably, the driving mechanism includes a drive shaft that is vertically rotatably mounted on the box cover, and the wire mesh demister is coaxially and detachably mounted on the drive shaft.

[0010] Preferably, the housing is a cylindrical structure, the drive shaft is coaxially arranged with the housing, and the diameter of the wire mesh demister is less than or equal to the inner diameter of the housing.

[0011] Preferably, the inside of the box is further provided with a grid-like support plate, and a wire mesh defoaming plate is provided between each two adjacent support plates.

[0012] Preferably, an installation sleeve is provided at the center of the support plate, the installation sleeve is coaxially sleeved on the outer periphery of the drive shaft, a limiting member is provided between the installation sleeve and the drive shaft, a limiting sleeve is also sleeved on the drive shaft, and the limiting sleeve and the drive shaft are fixed to each other by a locking member.

[0013] Preferably, each of the two adjacent support disks has a plurality of pins on its opposite sides, the pins are evenly distributed on the support disks, and the pins extend parallel to the axial direction of the support disks.

[0014] Preferably, the limiting sleeve has multiple fan blades evenly distributed around its outer circumference.

[0016] Preferably, the inner circumferential surface of the housing is provided with spirally distributed guide grooves, and the central axis of the guide grooves coincides with the axis of the housing.

[0017] The vertical vaporizer of this invention with good demisting effect has the following advantages: When gas carrying liquid droplets passes through the wire mesh demisting disc, the liquid droplets come into contact with the wire mesh and adhere to the surface of the wire mesh, while the gas passes through the gaps between the wire mesh, thereby achieving demisting of the gas; the slow rotation of the wire mesh demisting disc allows the wire mesh to actively capture liquid droplets, improving the demisting effect of the gas; the rapid rotation of the wire mesh demisting disc allows the collected liquid droplets to be thrown away by centrifugal force, thereby cleaning the wire mesh demisting disc and improving the demisting effect.

[0025] 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.

[0026] 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.

[0027] like Figure 1-3 As shown, a vertical vaporizer with good demisting effect includes a vaporizer body 1 with an air outlet 101 at the top, a demisting box 2 connected to the air outlet 101, a plurality of wire mesh demisting discs 5 stacked inside the demisting box 2, and a drive mechanism 3 for driving the wire mesh demisting discs 5 to rotate on the demisting box 2.

[0028] In the vaporizer described above, after the liquid raw material is heated and vaporized inside the main body 1, it enters the demister 2 through the gas outlet 101. Each wire mesh demister 5 is stacked along the flow direction of the gas inside the demister 2, so that the gas passes through each wire mesh demister 5 in sequence. During this process, the liquid droplets in the gas are captured by the wire mesh and accumulate on the wire mesh, while the gas penetrates the wire mesh demister 5 through the gaps between the wire meshes. In this way, the liquid droplets inside the gas can be removed, reducing the impact on subsequent processing steps. The wire mesh demister 5 can be made of 316L stainless steel or polytetrafluoroethylene. Both of these materials can withstand the high temperature and corrosion of 2-cyanopyridine raw material vaporization, which can extend the service life of the wire mesh demister 5.

[0029] Compared to existing Pall ring demisting, the wire mesh demister 5 has a finer wire mesh structure with smaller pores. When gas passes through, droplets easily collide and adhere to the fine wires due to inertia, interception, and diffusion, thus improving the demisting effect. Furthermore, the wire mesh demister 5 is driven to rotate slowly by the drive mechanism 3, allowing the wire mesh to actively capture droplets. Because the wire mesh demister 5 rotates slowly, the captured droplets can effectively remain on the wire mesh and gradually gather into larger droplets, preventing them from separating from the wire mesh and entering the gas again, thereby improving the demisting effect of the vaporizer. When a large amount of droplets accumulate on the wire mesh, the rotation speed of the wire mesh demister 5 can be increased, causing the accumulated droplets to separate under centrifugal force, thus achieving self-cleaning of the wire mesh demister 5. This reduces the impact of accumulated droplets on the airflow and droplet absorption effect of the wire mesh demister 5, further improving the demisting effect of the vaporizer.

[0030] Further improvements include, for example Figure 2 As shown, the demister 2 includes a box body 201 with a box cover 202 on the top. The bottom of the box body 201 has an air inlet pipe 204 that connects to the air outlet 101. An exhaust pipe 203 is provided on the box cover 202. Gas enters the interior of the demister 2 through the air inlet pipe 204, is demisted by the wire mesh demister disc 5, and is discharged from the exhaust pipe 203. The gas flows vertically upward, thus achieving liquid-liquid separation through the gravity of the liquid itself, improving the demisting effect of the vaporizer. The demister 2 is divided into a box cover 202 and a box body 201, which allows for easy disassembly and maintenance of the internal components of the demister 2, improving the convenience of vaporizer maintenance.

[0031] Further improvements include, for example Figure 3 As shown, the drive mechanism 3 includes a drive shaft 302 that is vertically rotatably mounted on the cover 202, and a wire mesh demister 5 that is coaxially and detachably mounted on the drive shaft 302. The drive mechanism 3 also includes a motor 301 fixed on the cover 202, and the motor 301 is connected to the drive shaft 302 for transmission; the motor 301 drives the drive shaft 302 to rotate, thereby driving the wire mesh demister 5 to rotate.

[0032] Further improvements include, for example Figure 3 As shown, the housing 201 has a cylindrical structure, and the drive shaft 302 is coaxially arranged with the housing 201. The diameter of the wire mesh demister 5 is less than or equal to the inner diameter of the housing 201. The cylindrical structure of the housing 201 makes it easier to fit the wire mesh demister 5, thereby effectively controlling the gap between the wire mesh demister 5 and the inner wall of the housing 201. When specifically setting the wire mesh demister 5, the gap between the two can be minimized as much as possible while ensuring that the edge of the wire mesh demister 5 does not contact the housing 201. This can reduce the wear between the wire mesh demister 5 and the housing 201, and also reduce the amount of gas passing through the gap between the two, allowing more gas to pass through the inside of the wire mesh demister 5, thereby improving the demisting effect of the vaporizer.

[0033] Further improvements include, for example Figure 4 As shown, a grid-like support plate 6 is also stacked inside the housing 201, and a wire mesh defoaming plate 5 is provided between each two adjacent support plates 6; an installation sleeve 602 is provided at the center of the support plate 6, and the installation sleeve 602 is coaxially sleeved on the outer periphery of the drive shaft 302. A limiting component is provided between the installation sleeve 602 and the drive shaft 302, and a limiting sleeve 4 is also sleeved on the drive shaft 302. The limiting sleeve 4 and the drive shaft 302 are fixed to each other by a locking component. The support plate 6 is connected to the drive shaft 302 via the mounting sleeve 602. The limiting components include a limiting strip axially disposed on the drive shaft 302 and a limiting groove formed on the inner wall of the mounting sleeve 602. The two components cooperate to maintain synchronous rotation between the drive shaft 302 and the support plate 6, preventing slippage. Each wire mesh demister 5 has a support plate 6 on both sides, allowing the support plate 8 to clamp the wire mesh demister 5 from both sides, thus providing support and preventing deformation of the wire mesh demister 5 during use. The shape is adjusted to maintain the demisting effect of the wire mesh demister 5. During installation, the wire mesh demister 5 and the support plate 6 are sequentially placed on the drive shaft 302. Then, a limiting sleeve 4 is placed at the bottom and fixed to the drive shaft 302 with bolts 401. The limiting sleeve 4 fixes the support plate 6 and the wire mesh demister 5 to the drive shaft 302. During disassembly, the limiting sleeve 4 is removed first to disassemble the wire mesh demister 5 and the support plate 6, which improves the convenience of vaporizer maintenance.

[0034] Further improvements include, for example Figure 4 As shown, multiple pins 601 are provided on the opposite sides of each of the two adjacent support disks 6. The pins 601 are evenly distributed on the support disks 6 and extend parallel to the axial direction of the support disks 6. The pins 601 are inserted into the interior of the wire mesh demister disk 5, which can fix the wire mesh demister disk 5 and the support disks 6 to each other. The pins 601 can support the wire mesh demister disk 5 from the inside, so that the pores inside the wire mesh demister disk 5 can be kept uniform during the rotation, reducing the probability of deformation and improving its demisting effect. In addition, the pins 601 can support between two adjacent support disks 6 to limit the minimum gap between the two support disks 6, thereby controlling the amount of compression of the wire mesh demister disk 5 by the support disks 6, so as to ensure the air volume and demisting effect of the wire mesh demister disk 5.

[0035] Further improvements include, for example Figure 6 As shown, multiple fan blades 402 are evenly distributed around the outer circumference of the limiting sleeve 4. The fan blades 402 promote the flow of gas inside the demister box 2, thereby allowing the gas to pass through the multi-layer wire mesh demister disc 5 more efficiently, ensuring the demister effect of the gas while also improving the gas throughput efficiency.

[0036] Further improvements include, for example Figure 3 and 5 As shown, the inner bottom wall of the housing 201 and the inner bottom wall of the cover 202 are both conical structures. The conical design of the inner bottom wall of the housing 201 allows the dripping liquid droplets to flow back into the vaporizer body 1 for re-vaporization, reducing the accumulation of liquid droplets inside the demister 2. The conical design of the inner bottom of the cover 202 allows the wire mesh demister 5 to guide the liquid droplets when it rotates rapidly to remove them, guiding the liquid droplets downwards along the conical surface, reducing the probability of liquid droplets entering the exhaust pipe 203, thereby improving the demister effect of the vaporizer.

[0037] Further improvements include, for example Figure 5 As shown, a spirally distributed guide groove 205 is provided on the inner circumferential surface of the housing 201, with the central axis of the guide groove 205 coinciding with the axis of the housing 201. The spirally distributed guide groove 205, during the rapid rotation and removal of liquid mist by the wire mesh demister 5, guides the liquid mist thrown onto the side wall of the housing 201 to flow downwards along the guide groove 205, thereby reducing the accumulation of liquid mist on the side wall of the housing 201 and decreasing the probability of liquid mist flowing upwards into the exhaust pipe 203, thus improving the demisting effect of the carburetor.
