Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bromine production, in particular to a mixed reaction kettle for bromine production with adjustable reactant inlet amount. Background Art
[0002] Bromine is a kind of important material in the chemical industry, mainly used for preparing bromides, and used as common analytical reagents, oxidants, absorbents for ethylene and heavy hydrocarbons, and brominating agents for organic synthesis in the fields of medicine, pesticides, dyes, spices, photographic materials, fire extinguishing agents, mineral processing, metallurgy, leather tanning, water purification, etc.
[0003] In the bromine production process, chlorine gas needs to be introduced into brine containing bromine elements. The bromide ions in the brine can be oxidized into elemental bromine by chlorine oxidation. The reaction between chlorine gas and brine needs to be carried out in a corresponding reactor.
[0004] The existing bromine production reactors gradually exposed their shortcomings during use, mainly in the following aspects:
[0005] First, as the chemical reaction continues, the amount of reactants in the reactor gradually decreases and the reaction rate gradually slows down. Therefore, the amount of chlorine consumed in the same period of time decreases. However, chlorine is usually introduced directly into the reactor through an air inlet pipe. Chlorine is continuously input into the reactor at a certain rate, and the chlorine that has not reacted is treated as exhaust gas, which is easy to cause waste.
[0006] Second, the air inlet pipe containing chlorine is directly inserted into the brine solution to react with the brine, which easily leads to a short contact time between the chlorine and the brine. The brine and the chlorine cannot be fully mixed, so the reaction process cycle is long, affecting the production efficiency of bromine.
[0007] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0038] like Figures 1 to 5 As shown, a mixed reactor for bromine production with an adjustable amount of reactants entering the reactor comprises a fixed reactor body 5, wherein an adjusting component 12 and a mixing component 13 are arranged vertically inside the reactor body 5.

[0040] The adjustment component 12 includes an upper rotating sleeve 23 which is coaxial with the reactor body 5 and has a sealed bottom. A sealing strip 25 is fixedly provided on the inner wall of the upper rotating sleeve 23 to cover the reactor body 5. An air inlet pipe 9 which is rotatably connected to the upper rotating sleeve 23 is coaxially provided inside the upper rotating sleeve 23. The bottom of the air inlet pipe 9 is sealed. The outer wall of the air inlet pipe 9 is frictionally abutted against the sealing strip 25. The upper end of the air inlet pipe 9 sequentially passes through the upper rotating sleeve 23 and the reactor body 5 to extend to the outside and is fixedly connected to the reactor body 5.
[0041] A plurality of outer ventilation grooves 18 are evenly distributed along the circumference of the outer wall of the upper rotating sleeve 23, and the outer ventilation grooves 18 penetrate the upper rotating sleeve 23 and the sealing strip 25. A plurality of inner ventilation grooves 24 are evenly distributed along the circumference of the outer wall of the air inlet pipe 9, and the number of the outer ventilation grooves 18 and the inner ventilation grooves 24 are equal and the shape is the same.
[0042] When the upper rotating sleeve 23 rotates, the overlapping area of the outer ventilation groove 18 and the inner ventilation groove 24 is adjusted, thereby adjusting the air intake volume.
[0043] When the upper rotating sleeve 23 rotates until the inner ventilation groove 24 is completely blocked by the sealing strip 25, the chlorine gas inlet passage is closed.
[0044] The mixing assembly 13 includes a driving shaft 4 which is coaxial with the reactor body 5 and is rotatably arranged. A plurality of stirring blades 3 which are symmetrically arranged along the axial section of the driving shaft 4 are vertically arranged in parallel on the outer wall of the driving shaft 4.
[0045] The drive shaft 4 is also fixed with two connecting pipes 14 symmetrically arranged along its axial section. The connecting pipes 14 are both arranged vertically and are both connected to the upper rotating sleeve 23. The bottom of the connecting pipe 14 is sealed, and the outer wall of the connecting pipe 14 is evenly distributed along its axial direction with a plurality of vent holes 17 penetrating therethrough.
[0046] When the driving shaft 4 rotates, the vent holes 17 on the connecting pipe 14 can spray chlorine into the brine evenly, and at the same time, the stirring blades 3 can stir the chlorine and the brine to make the chlorine and the brine fully contact.
[0047] A rotatably mounted hollow plate disc 21 is sleeved on the outer wall of the air inlet pipe 9 , and the top of the upper rotating sleeve 23 extends upward and is fixedly connected to the bottom of the hollow plate disc 21 .
[0048] The bottom of the hollow plate disc 21 is also fixedly connected with a fixed tube 26 coaxially arranged therewith. The inner diameter of the fixed tube 26 is larger than the outer diameter of the upper rotating sleeve 23. A lower rotating sleeve 27 is rotatably mounted on the outer wall of the fixed tube 26 below the upper rotating sleeve 23.
[0049] The lower end of the lower rotating sleeve 27 extends to the bottom of the fixed pipe 26 and is sealed. The upper ends of the two connecting pipes 14 both extend upward and are connected to the inner cavity of the lower rotating sleeve 27 .
[0050] A driven gear 22 fixedly connected to the hollow plate disc 21 is mounted on its outer wall. A rotating shaft 20 is provided at the inner top of the reactor body 5 for rotation along the vertical line. A driving gear 19 meshing with the driven gear 22 is fixedly connected to the bottom of the rotating shaft 20 .
[0051] The top of the rotating shaft 20 passes through the reactor body 5 and is fixedly connected to a horizontally arranged rotating plate 8 , on which a vertically slidable limiting rod 11 is inserted, and a plurality of limiting holes 6 matching the limiting rod 11 are evenly distributed on the top of the reactor body 5 .
[0052] A pressure sensor 10 for detecting the internal air pressure of the reactor body 5 is fixedly provided on the top of the reactor body 5 .
[0053] The top and bottom of the reactor body 5 are respectively provided with an exhaust pipe 7 and a liquid discharge pipe 2 which are connected to the inner cavity thereof.

[0056] The working principle of this device is:
[0057] When chlorine is introduced into the brine in the reactor body 5, the chlorine enters the reactor body 5 through the air inlet pipe 9. The chlorine in the air inlet pipe 9 passes through the inner ventilation groove 24, the outer ventilation groove 18, the fixed pipe 26, the lower rotating sleeve 27 and the connecting pipe 14 in turn, and is finally sprayed to the brine through the ventilation hole 17 on the connecting pipe 14. After the reaction is carried out for a period of time, the bromide ions in the brine are reduced. When the amount of chlorine introduced needs to be reduced, the limit rod 11 is pulled upward to separate it from the limit hole 6, and the rotating rod 11 is rotated. The plate 8 drives the rotating shaft 20, the driving gear 19, the driven gear 22, the hollow plate disc 21, the upper rotating sleeve 23 and the sealing strip 25 to rotate, the overlapping area of the outer ventilation groove 18 and the inner ventilation groove 24 is reduced, and the amount of chlorine introduced is reduced. According to the reaction process of chlorine and brine, the rotating plate 8 is rotated to a corresponding position, and the limiting rod 11 is inserted into the corresponding limiting hole 6 for limiting, so as to realize the function of real-time adjustment of the input amount of chlorine and reduce the waste of chlorine.
[0058] When the brine reacts with the chlorine, the driving motor 1 drives the driving shaft 4 and the stirring blade 3 to rotate, and at the same time, the driving shaft 4 drives the connecting rod 16, the limiting sleeve 15 and the connecting pipe 14 to rotate, and the vent 17 on the connecting pipe 14 continuously and evenly sprays chlorine into the brine, and the stirring blade 3 stirs the brine and the chlorine, so that the chlorine and the brine are fully contacted, thereby improving the production efficiency of bromine.
[0059] The air pressure sensor 10 can detect the air pressure in the reactor body 5 to prevent the exhaust pipe 7 from being blocked and causing a safety hazard due to excessive internal air pressure.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
