Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a reaction kettle system. Background Art

[0002] Conventional reactors consist of a reactor body, a motor, and a stirring device, which can meet 90% of reaction requirements. However, when encountering some materials with high density and easy aggregation and sedimentation, conventional reactors cannot efficiently homogenize them, which not only affects the reaction efficiency, but also causes material waste and reduces production efficiency.

[0003] The synthesis reaction of accelerators is mostly produced by the reaction of inorganic acids with aluminum hydroxide or other aluminum salts. However, aluminum salts generally have a high density and are easily deposited at the bottom of the reactor after being added. They cannot effectively contact with the inorganic acid, resulting in insufficient reaction, which in turn leads to decreased performance and stability of the final accelerator. Utility Model Content

[0024] refer to Figure 1 The present application provides a reactor system, which includes a reactor body 1, a coil assembly 2 and an air compressor 3. The interior of the reactor body 1 is used to accommodate inorganic acid and aluminum salt and provide a synthesis reaction for the inorganic acid and aluminum salt. The coil assembly 2 is arranged at the bottom of the reactor body 1 and is arranged around the inner side wall of the reactor body 1. The coil assembly 2 is provided with an air outlet 21, which is used to output a purge gas to the interior of the reactor body 1 to purge the bottom of the reactor body 1; the air compressor 3 is arranged outside the reactor body 1, and the air compressor 3 is connected to the coil assembly 2. The air compressor 3 is used to output a purge gas to the coil assembly 2.

[0025] The present application is provided with a coil assembly 2 at the bottom of the reactor body 1, and the coil assembly 2 is connected to the air compressor 3. The air compressor 3 is used to transport high-pressure gas into the coil assembly 2. The coil assembly 2 outputs the high-pressure gas as a purge gas to purge the bottom of the reactor body 1. When the inorganic acid and the aluminum salt react, the air compressor 3 transports stable purge gas to the coil assembly 2. The coil assembly 2 purges the aluminum salt, which can evenly distribute the aluminum salt put into the reactor body 1 and prevent the aluminum salt from gathering at the bottom of the reactor body 1, so that the aluminum salt can be distributed more evenly, allowing the reaction of the inorganic acid and the aluminum salt to be more sufficient, thereby improving the reaction efficiency and product conversion rate, and improving production efficiency.

[0026] Specifically, the reactor body 1 is made of enamel or stainless steel, and the coil assembly 2 is made of enamel or stainless steel.

[0027] In this embodiment, the specification of the reactor body 1 is 10 cubic meters, and the power of the air compressor is not less than 15KW.

[0028] refer to Figure 1 The reactor system also includes a main pipeline 4. A discharge port 11 is opened at the bottom of the reactor body 1. The main pipeline 4 is connected to the coil assembly 2 through the discharge port 11. The main pipeline 4 is also connected to the air compressor 3. A part of the purge gas output by the air compressor 3 is output to the discharge port 11 to purge the aluminum salt at the discharge port 11, which can prevent the aluminum salt from clogging the discharge port 11 and the main pipeline 4, thereby avoiding the problem of performance degradation and stability reduction of the final produced quick-setting agent. The other part of the purge gas enters the coil assembly 2 through the discharge port 11, and purges the aluminum salt through the coil assembly 2, thereby increasing the purge range and further improving the uniformity of the aluminum salt.

[0029] Specifically, the pressure of the purge gas is greater than the gravity of the material, and the material is a mixture of inorganic acid, aluminum salt and its reactants. Only in this way can the material at the discharge port 11 remain suspended when the purge gas is purged therewith, and the material will not flow downward in the main pipeline 4 under the action of gravity.

[0030] refer to Figure 1 The reactor system further includes a first stop valve 5 , which is disposed at one end of the main pipeline 4 away from the discharge port 11 . The first stop valve 5 is used to control the on-off of the main pipeline 4 .

[0031] refer to Figure 1The reactor system of the present application also includes a branch pipe 6, one end of which is connected to the discharge port 11 through the main pipe 4, and the branch pipe 6 is located between the discharge port 11 and the first stop valve 5. The other end of the branch pipe 6 is connected to the air compressor 3. The purge gas output by the air compressor 3 enters the discharge port 11 through the branch pipe 6 and the main pipe 4 in sequence, and is divided into two parts at the discharge port 11. One part is directly output through the discharge port 11 and purges the aluminum salt at the discharge port 11, and the other part enters the coil assembly 2 through the discharge port 11 and purges the aluminum salt through the coil assembly 2.

[0032] Specifically, the main pipe 4 is vertically arranged at the bottom of the reactor body 1, and the branch pipe 6 is horizontally arranged in the middle of the main pipe 4. With this arrangement, when discharging materials, they can flow into the main pipe 4 under the action of gravity without entering the branch pipe 6.

[0033] refer to Figure 1 The reactor system of the present application further includes a second stop valve 7 , which is arranged on the branch pipe 6 and located between the air compressor 3 and the discharge port 11 . The second stop valve 7 is used to control the on-off of the branch pipe 6 .

[0034] Specifically, during normal production, the first stop valve 5 is closed to prevent unfinished materials from flowing out of the discharge port 11. During production, the air compressor 3 is first turned on, followed by the second stop valve 7. The purge gas enters the main pipeline 4 through the branch pipeline 6. A portion of the purge gas enters the coil assembly 2 through the discharge port 11 and performs a purge, while the remaining portion is directly output from the discharge port 11 and performs a purge. After production is completed, the second stop valve 7 is first closed, followed by the air compressor 3, to prevent the materials in the reactor body 1 from flowing back into the air compressor 3 and damaging the compressor. The first stop valve 5 is then opened, and the logistics flow to the outside through the discharge port 11 and the first stop valve 5. After the discharge is basically completed, the air compressor 3 and the second stop valve 7 can be opened to blow the remaining materials in the main pipeline 4 and the branch pipeline 6 out of the first stop valve 5. Finally, the first stop valve 5, the second stop valve 7, and the air compressor 3 are closed.

[0035] refer to Figure 1 The coil assembly 2 includes a main coil 22 and a sub-coil 23. The main coil 22 is arranged around the inner wall of the reactor body 1. The main coil 22 is provided with an air outlet 21. One end of the sub-coil 23 is connected to the main pipeline 4 through the discharge port 11, and the other end of the sub-coil 23 is connected to the air outlet 21.

[0036] Specifically, the gas outlet 21 is located at the bottom of the main coil 22. Because aluminum salts tend to settle, the purge gas, when discharged from the bottom, creates an upward flow. This flow stirs the material, enhancing its circulation and mixing, thereby improving the uniformity of aluminum salt distribution and preventing localized high-concentration sedimentation.

[0037] There are multiple gas outlets 21 and multiple sub-coils 23. The multiple gas outlets 21 are spaced apart along the circumference of the main coil 22. The multiple sub-coils 23 are spaced apart along the circumference of the discharge port 11, and the sub-coils 23 are connected to the gas outlets 21 in a one-to-one correspondence. The multiple gas outlets 21 enable omnidirectional purge of the aluminum salt, thereby further improving the uniformity of the aluminum salt distribution.

[0038] Specifically, when adding solid materials such as aluminum salt, the air compressor 3 is turned on and the coil assembly 2 is used to purge the aluminum salt. When adding inorganic acid, the air compressor 3 is turned off to prevent the coil assembly 2 from bringing out a large amount of acid gas when purging the inorganic acid. After the inorganic acid is added, the air compressor 3 is turned on to purge the aluminum salt so that the inorganic acid and the aluminum salt react fully. At this time, under the action of the purge gas, the inorganic acid liquid flowing into the coil assembly 2 and the main pipeline 4 will also be blown out and flow back into the interior of the reactor body 1. After turning off the air compressor 3, the material will flow to the first stop valve 5 and the second stop valve 7. Since the first stop valve 5 and the second stop valve 7 are already closed, the logistics will be blocked by the first stop valve 5 and the second stop valve 7 to prevent further flow of the material. When the air compressor 3 is turned on and the second stop valve 7 is opened, the material will be blown back into the interior of the reactor body 1 under the action of the purge gas.

All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
