Description

Technical Field

[0001] The utility model relates to the technical field of fluosilicic acid preparation, and particularly relates to an absorber. Background Art

[0002] In the chemical industry, a large amount of silicon tetrafluoride (SiF4) waste gas is generated. Silicon tetrafluoride is a colorless gas with a pungent odor, which can cause irritation and damage to the eyes, nose, throat and other parts. If directly discharged, people exposed to silicon tetrafluoride waste gas for a long time may experience symptoms such as headache, vomiting, chest tightness, and difficulty breathing, posing a serious threat to physical health. To avoid threatening human health, factories now use absorbers to absorb silicon tetrafluoride, and silicon tetrafluoride is converted into fluosilicic acid (H2SiF6) through a hydrolysis reaction. Fluosilicic acid can be used in many aspects such as basic chemical raw materials, metal treatment and electroplating, wood preservation, brewing and disinfection.

[0003] The existing absorber includes a tank body. The tank body is a square trough tank. A rotary spraying device is provided at the top of the tank body. The inner wall of the tank body is made of PPH lining material. The rotary spraying device is a conical barrel. A water pipe is connected to the top end of the conical barrel. A number of through holes are provided on the side wall of the conical barrel. The larger diameter end of the conical barrel is rotatably connected to the top of the tank body. The conical barrel is driven by a motor to rotate in the tank body. The smaller diameter end of the conical barrel extends into the tank body so that the whole conical barrel is suspended in the tank body. Silicon tetrafluoride is absorbed into the tank body, water is introduced into the conical barrel, and the conical barrel rotates at a high speed to generate water mist and spray it into the tank body. The water mist acts as an absorbent to react with silicon tetrafluoride to generate fluosilicic acid (H2SiF6) and silica gel (SiO2·nH2O). Since the bottom end surface of the tank body is a plane, when the conical barrel rotates at a high speed, vortices will appear at the bottom end of the tank body, affecting the spraying effect of the conical barrel, being not conducive to the full contact between silicon tetrafluoride and the water mist for reaction, and affecting the reaction effect and reaction efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an absorber to solve the problem that vortices will appear at the bottom end of the tank body when the conical barrel rotates at a high speed, affecting the contact effect between silicon tetrafluoride and the water mist.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] An absorber includes a tank body and a conical barrel suspended in the tank body. A cross is fixedly connected to the bottom end surface in the tank body and protrudes upward. The cross is located below the conical barrel. Support blocks are fixedly supported at the four ends and the intersection point in the middle of the cross, and the support blocks make the cross arranged in the air.

[0007] The basic principle and beneficial effects of the above technical solution are as follows: When the conical barrel rotates at high speed, the cross on the bottom end of the tank body can increase the resistance of liquid flow, so that the liquid is more obstructed during the flow process, thereby slowing down the flow speed and preventing the formation of vortices at the bottom end of the tank body. If vortices are formed, when the spray enters the vortex area, the spray droplets will be strongly disturbed by the vortex airflow. This disturbance will change the movement trajectory and speed of the droplets, affecting the spray effect of the conical barrel, enabling silicon tetrafluoride to fully contact and react with the water mist, and not affecting the reaction effect of silicon tetrafluoride and the production efficiency of fluosilicic acid.

[0008] Further, a plurality of tank compartments are provided in the tank body. Each tank compartment is provided with a conical barrel and a cross. Arc-shaped transition plates are provided at the four right-angled corners of each tank compartment, making the tank compartment square on the outside and round on the inside. Compared with the existing square tank compartments, there are no 90-degree angles at the four corners of the square-on-the-outside-and-round-on-the-inside tank compartments, so there are no dead zones in the angle areas of the liquid inside the tank compartments, and crystals will not accumulate in these areas.

[0009] Further, a partition board is provided between the plurality of tank compartments. The partition board separates the plurality of tank compartments from each other, so that the operation conditions between the plurality of tank compartments do not interfere with each other.

[0010] Further, an observation window is provided on the outer side of the tank body. The observation window is formed by inlaying transparent glass on the side wall of the tank body. Each tank compartment among the plurality of tank compartments corresponds to an observation window. The reaction conditions inside each tank compartment can be conveniently observed through the transparent observation window.

[0011] Further, the inner wall of the tank body is made of a steel-lined rubber material. The steel-lined rubber material has a good expansion coefficient. When the temperature difference inside the tank body changes, the steel-lined rubber material is not easily damaged, so that the inner lining of the tank body is not easily damaged, and the service life of the equipment is guaranteed.

[0012] Further, an inverted insertion pipe is connected to the bottom end of the tank body. The tank body can be conveniently emptied through the inverted insertion pipe. Description of the Drawings

[0016] The following is a further detailed description through specific embodiments:

[0017] The embodiment is basically as shown in the attached Figure 1-2 figure:

[0018] An absorber, as Figure 1 shown, includes a tank body 1. The inner wall of the tank body 1 is made of a steel-lined rubber material. The tank body 1 is evenly divided into three trough tanks 2 from left to right. A conical barrel 3 is rotatably connected to the top end of each trough tank 2. A number of through holes 4 are provided on the side wall of the conical barrel 3. The larger-diameter end of the conical barrel 3 is rotatably connected to the top of the trough tank 2. The conical barrel 3 is driven by a motor to rotate in the trough tank 2. The smaller-diameter end of the conical barrel 3 extends into the trough tank 2 so that the whole conical barrel 3 is suspended in the trough tank 2. A cross 5 protruding upward is fixedly connected to the bottom end surface in each trough tank 2. The cross 5 is directly below the conical barrel 3. Support blocks 6 are fixedly supported at the four ends and the intersection point in the middle of the cross 5. The support blocks 6 make the cross 5 arranged in a suspended manner. An observation window 7 is provided on the outer side of the tank body 1. The observation window 7 is formed by embedding transparent glass on the side wall of the tank body 1. Each of the three trough tanks 2 corresponds to an observation window 7. A reverse insertion pipe (not shown in the figure) is communicated with the bottom end of the tank body 1. As Figure 2 shown, arc-shaped transition plates 8 are provided at the four right-angle corners of each trough tank 2, making the trough tank 2 have a square outer shape and a circular inner shape. Moreover, a partition plate 9 is provided between each two trough tanks 2 to separate different trough tanks 2 from each other.

[0019] The specific implementation process is as follows:

[0020] When the conical barrel 3 rotates at a high speed, the cross 5 at the bottom end of the tank body 1 can increase the resistance of the liquid flow, so that the liquid is more obstructed during the flow process, thereby slowing down the flow speed, avoiding the formation of vortices at the bottom end of the tank body 1, affecting the spraying effect of the conical barrel 3, enabling silicon tetrafluoride to fully contact with the water mist and react, and not affecting the reaction effect of silicon tetrafluoride and the production efficiency of fluosilicic acid.

It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
