Description

Technical Field

[0001] The invention belongs to the technical field of vaporizers, and in particular relates to an outlet control device for an industrial naphthalene vaporizer. Background Art

[0002] Industrial naphthalene vaporizer is a device used to heat industrial naphthalene from liquid to gaseous state, which is widely used in coal tar processing. Its main function is to heat industrial naphthalene to complete vaporization, and then further process and utilize it through a specific pipeline system.

[0003] The utility model patent with patent application number 201320530778.4 discloses a naphthalene vaporizer with a demister, which is provided with a demister; when the vaporized naphthalene passes through, the demister is used to block most of the impurities, droplets and bubbles, purify the quality of the vaporized naphthalene, protect the catalyst used, and ensure production safety.

[0004] However, after the demister is in operation, liquid droplets will condense inside it, which are easily carried away directly by the airflow, forming secondary entrainment; for this reason, the invention patent with patent application number 201710552557.X discloses a wire mesh demister with multiple defoaming, which first uses a double-layer guide plate to perform crude gas-liquid separation on steam, and then further separates it through the condensation mesh, and finally separates the fine gas-liquid through rotating blades. It adopts a multi-separation method to prevent the condensed droplets from being carried away by the airflow, but the separation of the droplets still relies on their own weight, and its separation effect is not high.

[0005] The utility model patent with patent application number 201720452183.X discloses a naphthalene vaporizer with anti-coking function, which removes the residual naphthalene at the heating tube by adding stirring cleaning and accelerating circulation to effectively prevent coking.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] like Figure 1-9As shown, an industrial naphthalene vaporizer outlet control device comprises a vaporizer 1 and a heating device 2. A heating jacket 3 is fixed in the vaporizer 1, and the heating device 2 is arranged in the heating jacket 3. The vaporizer 1 is provided with an inlet pipe 4 and an outlet pipe 5 which are connected with the inside thereof. Liquid raw materials are added into the vaporizer 1 through the inlet pipe 4, heated by the heating device 2 and radiated to the outside through the heating jacket 3. The liquid raw materials absorb the heat to form vaporized naphthalene, which is discharged through the outlet pipe 5.

[0039] A control device 6 is provided at the outlet pipe 5, through which the quality of naphthalene vapor can be effectively improved; the control device 6 specifically adopts the following structural arrangement.

[0040] The control device 6 includes a rotating screen block 7 and a movable screen block 8. A support plate 9 is provided at the outlet pipe 5. A rotating shaft 10 is rotatably connected to the support plate 9. The rotating screen block 7 is fixedly connected to the rotating shaft 10. The movable screen block 8 is sleeved outside the rotating screen block 7. There is a gap between the rotating screen block 7 and the movable screen block 8 to ensure that the ejected droplets have enough moving space so that they can adhere to the movable screen block 8.

[0041] The movable screen block 8 is fixedly connected to the outlet pipe 5 through an elastic connecting component 11. A driving ring 12 is fixed on the rotating shaft 10. A pushing protrusion 13 is provided on the driving ring 12. The pushing protrusion 13 cooperates with the elastic connecting component 11 to achieve the shaking of the movable screen block 8, thereby shaking the droplets on the movable screen block 8 into the vaporizer.

[0042] A heat exchange cleaning component 14 is provided on the heating sleeve 3, through which the outer surface of the heating sleeve 3 is cleaned and the heat dissipation contact area is increased; the heat exchange cleaning component 14 is transmission-connected to the rotating shaft 10, and the reciprocating movement of the heat exchange cleaning component 14 drives the rotating shaft 10 to reciprocate, that is, forward rotation → reverse rotation → forward rotation → reverse reciprocating rotation.

[0043] Before the vaporized naphthalene produced in the vaporizer is discharged through the outlet pipe 5, it needs to be purified by the rotating screen block 7 and the movable screen block 8; during the purification process, it will condense into droplets on the rotating screen block 7 and the movable screen block 8, and there is a possibility that it will be entrained by the airflow.

[0044] The control device 6 cleans the outer surface of the heating sleeve 3 by the reciprocating movement of the heat exchange cleaning component 14; at the same time, it also drives the rotating shaft 10 to rotate back and forth, so that the rotating screen block 7 also rotates back and forth, and the centrifugal force generated by the rotation is used to throw the liquid onto the movable screen block 8; and the reciprocating rotation of the rotating shaft 10 drives the driving ring 12 to rotate back and forth as well, and the movable screen block 8 is shaken by pushing the protrusion 13 to cooperate with the elastic connecting component 11, so as to shake the droplets on the movable screen block 8 into the vaporizer.

[0045] That is, through the above-mentioned mechanism setting, the cleaning of the heating sleeve 3 is realized, and the separation of the liquid on the rotating screen block 7 and the movable screen block 8 is also realized. The separation process is achieved by applying external force, and the separation effect is obvious because it only relies on the dead weight.

[0046] Furthermore, the elastic connection component 11 includes a mounting ring 15 and an elastic arc plate 16. A plurality of elastic arc plates 16 are provided. The plurality of elastic arc plates 16 are fixed on the mounting ring 15 at intervals, and the intervals between adjacent elastic arc plates 16 form a liquid flow channel 17. At the same time, sufficient deformation space is left for each elastic arc plate 16.

[0047] The mounting ring 15 is fixedly connected to the outlet pipe 5 , the top of each elastic arc plate 16 is fixedly connected to the bottom of the movable screen block 8 , and a liquid storage area 18 is formed between the arc elastic plate and the inner wall of the outlet pipe 5 .

[0048] A wedge-shaped protrusion 19 that cooperates with the pushing protrusion 13 is fixed on the inner surface of the elastic arc plate 16; when the driving ring 12 reciprocates, the pushing protrusion 13 cooperates with the wedge-shaped protrusion 19, thereby pushing the corresponding elastic arc plate 16 to deform, and the remaining elastic arc plates 16 will also deform accordingly, so that the movable screen block 8 will shake (sway). The liquid on the movable screen block 8 is shaken off, and the shaken liquid slides along the inner wall of the outlet pipe 5 or along the outer surface of the elastic annular plate into the liquid storage area 18, and finally falls into the vaporizer 1 through the liquid flow channel 17.

[0049] Furthermore, the driving ring 12 is fixedly connected to the rotating shaft 10 through a plurality of baffles 20, so that the driving ring 12 not only drives the movable screen block 8 to shake, but also forms a baffle barrier area to hinder the naphthalene gas, that is, preliminarily purifies the quality of the naphthalene gas.

[0050] Furthermore, the shape of the baffle 20 is preferably an S-shaped baffle 20 .

[0051] Furthermore, the shape of the rotating screen block 7 is preferably conical.

[0052] Furthermore, the movable screen block 8 comprises an upper ring body 21, a cylinder body 22 and a lower ring body 23, wherein the upper ring body 21 is fixedly connected to the upper end of the cylinder body 22, and the lower ring body 23 is fixedly connected to the lower end of the cylinder body 22; the inner ring diameter of the upper ring body 21 is smaller than the inner ring diameter of the lower ring body 23. Through the above-mentioned structural arrangement, the rotating screen block 7 can be effectively "wrapped".

[0053] Furthermore, the heat exchange cleaning assembly 14 includes a linear moving mechanism 24 and a cleaning ring 25. There are several cleaning rings 25. The cleaning rings 25 are all slidably connected to the heating sleeve 3. The cleaning rings 25 are fixedly connected by connecting rods 26. Each cleaning ring is fixed with a circle of heat dissipation fins 27.

[0054] The linear moving mechanism 24 is arranged outside the vaporizer 1, and the moving part of the linear moving mechanism 24 is fixedly connected to any cleaning ring 25. Through the reciprocating movement of the moving part, each cleaning ring 25 is driven to reciprocate along the outer surface of the heating sleeve 3 to scrape off the material attached to the outer surface of the heating sleeve 3. At the same time, since each cleaning ring 25 is provided with a heat dissipation fin 27, the heat dissipation efficiency can be effectively improved, and the heat dissipation fin 27 is in a moving state (to avoid / reduce the residual naphthalene staying on its surface), and contacts and flushes with the liquid in the vaporizer 1, thereby cleaning it.

[0055] Specifically, the heat exchange cleaning assembly 14 is connected to the rotating shaft 10 through a gear rack mechanism, and the gear rack mechanism includes a driving gear 28 and a driving rack 29. The driving gear 28 is fixedly connected to the rotating shaft 10, and the driving rack 29 is fixedly connected to the connecting rod 26 and meshes with the driving gear 28. When each cleaning ring 25 is driven to reciprocate along the outer surface of the heating sleeve 3, the driving rack 29 is also driven to reciprocate through the connecting rod 26, and the rotating shaft 10 is driven to reciprocate by meshing with the driving gear 28 (forward rotation → reverse rotation → forward rotation → reverse reciprocating rotation).

[0056] Furthermore, the linear moving mechanism 24 uses a telescopic cylinder or a linear motor. Taking the telescopic cylinder as an example, its cylinder body is fixedly connected to the outer wall of the vaporizer 1, and its piston rod passes through the vaporizer 1 (a sliding sealing structure is provided at the passing point) and is fixedly connected to any cleaning ring 25.

[0057] Furthermore, a support plate 9 is provided in the vaporizer 1 , and the driving rack 29 is slidably connected to the support seat 30 , thereby providing good support for the driving rack 29 .

[0058] Furthermore, the vaporizer 1 is preferably placed horizontally, that is, it is arranged in a horizontal structure.

[0059] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments.
