Abstract
Description
Technical Field
[0001] This utility model relates to the field of titanium dioxide vacuum crystallization technology, and in particular to a titanium liquid demister. Background Technology
[0002] During the sulfuric acid process for titanium dioxide vacuum crystallization, the large, lightweight titanium dioxide foam on the upper layer of the molten titanium enters the vacuum pipe along the inner wall of the crystallization tank. After hydrolysis, the solid titanium dioxide adheres to the inner wall of the pipe, eventually clogging it. This narrows the diameter of the vacuum pipe, limits the vacuum pumping capacity, prolongs the vacuum crystallization time, and in severe cases, reduces titanium dioxide production. Therefore, it is essential to perform defoaming treatment on the molten titanium. Utility Model Content
[0003] To address the aforementioned technical defrosts, this invention provides a titanium liquid demister that separates titanium liquid demisters into gas and liquid phases during vacuum crystallization. This prevents the solidified titanium dioxide from adhering and causing pipe blockage, which would otherwise affect the normal production of titanium dioxide.
[0004] This utility model discloses a titanium liquid demister, including a first cylinder and a second cylinder, which are connected together. The top of the first cylinder is closed, and the lower end of the first cylinder is connected to the second cylinder. An air outlet is provided on the side wall of the first cylinder. A swirl plate is provided at the upper end of the second cylinder, and a swirl separator is provided at the lower end of the second cylinder. An air inlet is provided on the side wall of the second cylinder at the location corresponding to the swirl separator. The lower end of the second cylinder is closed, and a water outlet is provided at the center of the lower end of the second cylinder. A spray pipe is provided on the side wall of the first cylinder, extending to the center of the second cylinder. A downward spray head is provided on the spray pipe inside the second cylinder.
[0005] Swirl plates are arranged in a ring on the inner wall of the upper end of the second cylinder. A connecting shaft is set at the center of the upper end of the second cylinder, and the swirl plates are all fixedly connected to the connecting shaft. The swirl plates are arc-shaped plates, and the swirl plates are inclined. The top of the swirl plates is bent to one side to form a bending part, and the bending part is located on the same side of the arc-shaped concave part of the swirl plate.
[0006] The end of the bent portion is bent outward to form a drainage portion.
[0007] The first cylinder has a conical structure that is smaller at the top and larger at the bottom.
[0008] The lower end of the second cylinder is provided with a downward-facing conical closed structure, and the water outlet is located at the lowest end of the conical closed structure.
[0009] An inspection port is provided at the top of the first cylinder, and the inspection port is equipped with a flange plate for sealing the inspection port.
[0010] The titanium liquid demister obtained by this utility model can achieve gas-liquid separation by using a hydrocyclone separator and a hydrocyclone plate to separate titanium dioxide. At the same time, the spraying prevents titanium dioxide from adhering to the hydrocyclone plate, so that the titanium liquid can be discharged from the outlet, avoiding blockage of the pipeline, improving crystallization stability, and ensuring stable production of titanium dioxide.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0017] Example 1:
[0018] like Figures 1-5 As shown, this utility model discloses a titanium liquid demister, including a first cylinder 1 and a second cylinder 2, which are connected together. The top of the first cylinder 1 is closed, and the lower end of the first cylinder 1 is connected to the second cylinder 2. An air outlet 7 is provided on the side wall of the first cylinder 1. A swirl plate 4 is provided at the upper end of the second cylinder 2, and a swirl separator 3 is provided at the lower end of the second cylinder 2. An air inlet 5 is provided on the side wall of the second cylinder 2 at the location corresponding to the swirl separator 3. The lower end of the second cylinder 2 is closed, and a water outlet 6 is provided at the center of the lower end of the second cylinder 2. A spray pipe 8 is provided on the side wall of the first cylinder 1, and the spray pipe 8 extends to the center of the second cylinder 2. A downward spray head 9 is provided on the spray pipe 8 inside the second cylinder 2.
[0019] In practical use, the titanium liquid enters the hydrocyclone separator 3 in the second cylinder 2, achieving gas-liquid separation. The hydrocyclone separator 3 is a commercially available product, and its specific structure is known technology, so it will not be described in detail here. The titanium liquid and water in the hydrocyclone separator 3 will be discharged downwards from the outlet 6, which can be connected to a recovery pipe to recycle the titanium liquid. The separated airflow moves upwards and, as it enters the first cylinder 1 from the second cylinder 2, its flow direction changes under the action of the cyclone plate 4. A small amount of titanium liquid in the airflow will come into contact with the cyclone plate 4, adhere to the cyclone plate 4, and flow downwards into the bottom of the second cylinder 2, where it will be discharged from the outlet 6. Of course, to prevent titanium dioxide from adhering to the cyclone plate 4, a spray pipe 8 is installed at the upper end of the first cylinder 1, and a spray head 9 is installed at the end of the spray pipe 8 to spray water downwards, rinsing the titanium dioxide on the cyclone plate 4 and the hydrocyclone separator 3, thus preventing a large amount of titanium dioxide from adhering to the cyclone plate 4. The cyclone separator 3 and the cyclone plate 4 are used to perform secondary separation of the titanium liquid in the gas flow, which can prevent the titanium liquid from entering the vacuum pipeline and improve the stability of equipment operation.
[0020] Swirl plates 4 are arranged in a ring on the inner wall of the upper end of the second cylinder 2. A connecting shaft 12 is provided at the center of the upper end of the second cylinder 2. All swirl plates 4 are fixedly connected to the connecting shaft 12. The swirl plates 4 are arc-shaped plates. The swirl plates 4 are inclined. The top of the swirl plates 4 is bent to one side to form a bending part. The bending part is located on the same side of the arc-shaped concave part of the swirl plates 4.
[0021] The swirl plate 4 is an arc-shaped plate, and they are spaced apart in the same direction. When the airflow passes over it, it causes the airflow to swirl, thereby separating the molten titanium in the airflow. At the same time, a bend is provided at the top of the swirl plate 4 to block the upward movement, which can reduce the upward movement of the molten titanium with the airflow and make the separation of molten titanium more thorough.
[0022] The end of the bending section is bent outward to form a drainage section 14. The end of the bending section 13 is bent downward to form a drainage section 14, so that the titanium liquid attached to the bending section 13 can be better drained and dripped, avoiding it from adhering and sticking on the swirl plate 4, and improving the recycling rate of titanium liquid.
[0023] The first cylinder 1 has a conical structure that is smaller at the top and larger at the bottom. The conical structure design of the first cylinder 1 can effectively improve the airflow concentration before it is output from the outlet 7, resulting in better output stability.
[0024] The lower end of the second cylinder 2 is provided with a downward-facing conical closed structure, and the water outlet 6 is located at the lowest end of the conical closed structure. The conical closed structure at the bottom of the second cylinder 2 can collect the dripping titanium liquid and concentrate it at the lowest point, and also facilitate its discharge from the water outlet 6.
[0025] A maintenance port 10 is provided at the top of the first cylinder 1, and a flange plate 11 is provided on the maintenance port 10. The flange plate 11 is used to close the maintenance port 10. When needed, the flange plate 11 can be opened, and maintenance personnel can perform maintenance on the cyclone plate 4, cyclone separator 3, etc. through the maintenance port 10, making the operation more convenient.
[0026] Working principle: Titanium liquid droplets enter the cyclone separator 3 through the air inlet 5, where the airflow carrying titanium liquid undergoes primary separation. Moisture and a large amount of titanium liquid droplets flow downwards into the water outlet 6 for discharge, while the non-condensable gas after primary separation, carrying a small amount of titanium liquid droplets, rises and contacts the cyclone plate 4 for secondary gas-liquid separation. The titanium liquid drips into the bottom water outlet 6, while the non-condensable gas is output from the air outlet 7. A spray device washes and cleans the titanium liquid droplets adhering to the cyclone plate 4 and the cyclone separator 3, preventing excessive adhesion.
