Technical Field

[0001] The utility model relates to the technical field of ammonium sulfate preparation equipment, in particular to an ammonium sulfate preparation reaction kettle for desulfurization waste liquid. Background Art

[0002] In the coal chemical production process, a large amount of desulfurization waste liquid is usually discharged. After the desulfurization waste liquid is discharged, it will pollute the surrounding environment. In order to solve the problem of environmental pollution when the desulfurization waste liquid is discharged, a desulfurization waste liquid recovery device is usually used for desulfurization treatment, and the desulfurization wastewater is converted into clean water for secondary utilization.

[0003] For example, a desulfurization waste liquid treatment and reuse system disclosed in the Chinese utility model patent with announcement number CN209696685U includes: a desulfurization tower provided with a flue gas inlet, a desulfurization agent inlet, a desulfurization waste liquid outlet and an exhaust port, a filter press device, a reduction tower with a flocculant inlet in the tower body, a desulfurization waste liquid spreading device arranged in the tower body, an aeration device provided with an aeration nozzle group located at the lower side of the desulfurization waste liquid spreading device, a heating device, a flocculant feeding device, a sedimentation tank provided with a reduction clear liquid water pump, a desulfurization waste liquid water pump whose inlet is connected to the desulfurization waste liquid outlet, and a reduction liquid water pump whose inlet is connected to the inner cavity of the reduction tower; the waste residue outlet of the sedimentation tank is connected to the filter press device; the outlet of the desulfurization waste liquid water pump is connected to the desulfurization waste liquid spreading device; the outlet of the reduction liquid water pump is connected to the reduction liquid inlet provided in the sedimentation tank; the outlet of the reduction clear liquid water pump is connected to the desulfurization agent inlet.

[0004] The desulfurization waste liquid treatment and reuse system can remove sulfuric acid from wastewater through a series of desulfurization processes, converting wastewater into clean water for secondary utilization.

[0005] However, the above patent only provides a technical solution to the problem of desulfurization waste liquid discharge. In fact, there are many technical directions that can be developed to solve the problem of desulfurization waste liquid discharge and realize the secondary utilization of desulfurization waste liquid, such as:

[0006] How to convert desulfurization waste liquid into ammonium sulfate that can be used in agriculture, industry and medicine to achieve secondary utilization of desulfurization waste liquid.

[0007] Ammonium sulfate is used in agriculture as a commonly used nitrogen fertilizer, suitable for various soils and crops, and can provide the nutrients needed by plants. Ammonium sulfate is used in industry as it can be used in industries such as textiles, leather, and medicine, and has a variety of uses. In addition, ammonium sulfate can also be used to manufacture other chemical products, such as ammonium nitrate, ammonium phosphate, etc.

[0008] It can be seen that how to solve the discharge problem of desulfurization waste liquid in a new way and convert the desulfurization waste liquid into ammonium sulfate that can be used in multiple fields to achieve the secondary utilization of desulfurization waste liquid is a technical problem that our R&D personnel need to solve.

[0043] Beneficial effects:

[0044] The utility model provides a reaction kettle for preparing ammonium sulfate from desulfurized waste liquid, which has the following beneficial effects:

[0045] 1. In the utility model, during the reaction, the motor can drive the rotation of the scraper-type stirring mechanism by the rotation of its output shaft. At this time, the scraper-type stirring mechanism can rotate in the inner cavity of the reactor assembly, and when the scraper-type stirring mechanism rotates, the outer end of the scraper-type stirring mechanism can continuously slide in contact with the inner wall of the reactor body in a rotating manner, and at the same time can evenly stir the desulfurization waste liquid in the reactor assembly. While the scraper-type stirring mechanism evenly stirs the desulfurization waste liquid to make it fully react, it can also timely scrape off impurities adhering to the inner wall of the reactor body to avoid impurities remaining on the inner wall of the reactor body.

[0046] 2. In the utility model, when the desulfurized waste liquid is stirred by the scraper-type stirring mechanism, it can be filled into the desulfurized waste liquid in the reactor assembly through the ammonia delivery component. The delivery of ammonia can be coordinated with the scraper-type stirring mechanism. When the scraper-type stirring mechanism is stirring, ammonia is simultaneously added into the desulfurized waste liquid. The ammonia is immersed in the desulfurized waste liquid and can produce a chemical reaction with the sulfuric acid in the desulfurized waste liquid to generate ammonium sulfate.

[0047] 3. In the utility model, while the scraper-type stirring mechanism stirs the desulfurization waste liquid, it can accelerate the chemical reaction between sulfuric acid and ammonia in the desulfurization waste liquid. While accelerating the reaction, it can also enable the two to react more fully and generate ammonium sulfate after the reaction.

[0048] Fourth, in the utility model, the locking component is installed on the kettle cover and corresponds to one side of the ammonia delivery component. When one end of the ammonia delivery component penetrates upward, it can penetrate into the locking component and be locked and fixed by the locking component;

[0049] On the contrary, when the locking component is unlocked, the ammonia delivery component can be adjusted up and down on the reactor assembly, and when the ammonia delivery component is adjusted up and down, the ammonia delivery component can slide up and down on the locking component;

[0050] When the ammonia delivery component is adjusted up and down, the use position can be adjusted according to the actual operation needs;

[0051] After the use position adjustment is completed, the ammonia delivery component can be locked and fixed by using the locking component.

[0052] 5. In the present invention, the bottom opening of the discharge pipe is tilted downward, wherein the angle between the discharge pipe and the horizontal plane is preferably 30°-45°. When the downward tilt angle of the discharge pipe is between 30°-45°, the unloading effect is better.

[0053] 6. In the utility model, one end of the bottom of each L-shaped stirring rack can be in sliding contact with the bottom of the inner cavity of the kettle body. Since the bottom of each L-shaped stirring rack can be slidably connected with the bottom of the inner cavity of the kettle body when rotating, each L-shaped stirring rack can not only achieve the stirring effect, but also can timely scrape away impurities at the bottom of the inner cavity of the kettle body to avoid the accumulation of impurities at the bottom of the inner cavity of the kettle body.

[0054] 7. In the utility model, when the L-shaped stirring frame rotates, the rounded corner portion can slide in contact with the inner wall of the arc portion. Since impurities are easily precipitated and accumulated on the inner wall of each arc portion, when the rounded corner portion slides in contact with the inner wall of the arc portion, the impurities precipitated and accumulated on the inner wall of the arc portion can be scraped off in time.

[0055] 8. In the utility model, when the L-shaped stirring frame rotates, the outer edge of the scraper part can contact the inner wall of the kettle body. Since impurities can also adhere to the inner wall of the kettle body, the outer edge of the scraper part can timely scrape off the impurities attached to the inner wall of the kettle body when it contacts the inner wall of the kettle body.

[0056] 9. In the utility model, when the scraper-type stirring mechanism rotates in the desulfurization waste liquid, each L-shaped stirring rack can stir in the waste liquid, and each stirring wing rod can move synchronously with the movement of the L-shaped stirring rack to further enhance the stirring effect of the L-shaped stirring rack. At the same time, each stirring wing rod can perform fine stirring at different height layers of the waste liquid, so that the chemical reaction effect of sulfuric acid and ammonia in the desulfurization waste liquid can be further highlighted.

[0057] 10. In the present invention, the multiple through holes formed on each stirring wing rod can reduce the resistance of each stirring wing rod in the waste liquid, so that the waste liquid can pass through the stirring wing rod better.

[0058] 11. In the present invention, the ammonia filling pipe is the preferred form of the ammonia delivery component. The ammonia filling pipe is hollow inside, with an open top and a closed bottom. A plurality of ammonia spray holes are provided at the lower part of the side wall, and the top end can pass out from the reactor assembly through the insertion hole. Conversely, the bottom end of the ammonia filling pipe can also pass through the insertion hole into the reactor assembly.

[0059] Ammonia can be transported to the ammonia filling pipe and filled into the desulfurized waste liquid in the reactor assembly through the ammonia spray hole;

[0060] Since the ammonia filling pipe can pass through the insertion hole, the ammonia filling pipe can be adjusted up and down.

[0061] 12. In the present invention, the sleeve and the hexagon socket set screw are the preferred forms of the locking component. The upper end of the ammonia filling pipe can be inserted upward into the sleeve. After the ammonia filling pipe is inserted, the hexagon socket set screw can clamp and fix the ammonia filling pipe when tightened, thereby limiting the use position of the ammonia filling pipe.

[0062] When the hexagon socket set screw is loosened, the ammonia filling pipe can slide upward or downward on the sleeve, so that the position of the ammonia filling pipe can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] Embodiment 1

[0077] like Figure 1-10 As shown, the utility model provides a technical solution:

[0078] A reaction kettle for preparing ammonium sulfate from desulfurization waste liquid, comprising:

[0079] The reactor assembly includes a reactor body 1 and a reactor cover 2 detachably mounted on the reactor body 1;

[0080] The bottom of the kettle body 1 has an arc portion 101, and one side of the bottom of the kettle body 1 is connected to a discharge pipe 102, and a discharge valve 103 is installed on the discharge pipe 102;

[0081] When the discharge valve 103 is unscrewed, the material can be discharged through the discharge pipe 102. Conversely, during the reaction, the discharge valve 103 needs to be tightened to keep the discharge pipe 102 closed.

[0082] A feed pipe 201 is connected to one side of the top of the kettle cover 2, and an assembly hole 202 is opened at the center of the top of the kettle cover 2;

[0083] Among them, the feed pipe 201 is used for feeding the desulfurization waste liquid, specifically, as Fig.10 As shown, the waste liquid discharge pipe is used to transport and discharge the desulfurization waste liquid. One end of the waste liquid discharge pipe can be plugged into the feed pipe 201. After plugging, the waste liquid discharge pipe can pour the desulfurization waste liquid inside it into the reactor assembly;

[0084] The kettle cover 2 is installed on the top opening of the kettle body 1. After the kettle body 1 and the kettle cover 2 are installed, a plurality of hexagon socket fastening bolts 3 are installed between the kettle body 1 and the kettle cover 2. The kettle body 1 and the kettle cover 2 are fastened and installed by the plurality of hexagon socket fastening bolts 3.

[0085] Among them, by unscrewing each hexagon socket fastening bolt 3, it is convenient for maintenance personnel to clean the inside of the kettle body 1 and the kettle cover 2. After tightening each hexagon socket fastening bolt 3, the kettle body 1 and the kettle cover 2 can be fastened and installed to form a reactor assembly, so as to realize the preparation of ammonium sulfate;

[0086] The motor 4 is fixedly mounted at the top center of the kettle cover 2, and the output shaft of the motor 4 passes through the assembly hole 202 downward and extends to the top of the inner cavity of the kettle cover 2;

[0088] During the reaction, the motor 4 can drive the rotation of the scraper-type stirring mechanism by the rotation of its output shaft. At this time, the scraper-type stirring mechanism can rotate in the inner cavity of the reactor assembly, and when the scraper-type stirring mechanism rotates, one end of the outer side of the scraper-type stirring mechanism can continuously slide and contact with the inner wall of the reactor body 1 in a rotating manner, and at the same time, the desulfurized waste liquid in the reactor assembly can be uniformly stirred. While the scraper-type stirring mechanism uniformly stirs the desulfurized waste liquid to make it fully react, it can also timely scrape off impurities adhering to the inner wall of the reactor body 1 to prevent impurities from remaining on the inner wall of the reactor body 1;

[0089] An ammonia gas delivery component is movably mounted on the reactor assembly, one end of the ammonia gas delivery component is located in the inner cavity of the reactor body 1, and the other end of the ammonia gas delivery component passes through the reactor cover 2 to the outside;

[0091] Specifically, when the desulfurized waste liquid is stirred by the scraper-type stirring mechanism, it can be injected into the desulfurized waste liquid in the reactor assembly through the ammonia delivery component. The delivery of ammonia can be coordinated with the scraper-type stirring mechanism. When the scraper-type stirring mechanism is stirring, ammonia is simultaneously injected into the desulfurized waste liquid. The ammonia is immersed in the desulfurized waste liquid and can react chemically with sulfuric acid in the desulfurized waste liquid to generate ammonium sulfate.

[0092] When the scraper-type stirring mechanism stirs the desulfurized waste liquid, the chemical reaction between the sulfuric acid and ammonia in the desulfurized waste liquid can be accelerated. While accelerating the reaction, the two can also react more fully and generate ammonium sulfate after the reaction. The ammonium sulfate generated by the reaction can be used in agriculture, industry and medicine. When the sulfuric acid and ammonia in the desulfurized waste liquid react chemically, the desulfurized waste liquid can be reused. In a different way, the problem that the discharge of the traditional desulfurized waste liquid is prone to cause environmental pollution is solved; and a locking component, the locking component is installed on the kettle cover 2 and corresponds to one side of the ammonia conveying component. When one end of the ammonia conveying component penetrates upward, it can penetrate into the locking component and be locked and fixed by the locking component;

[0093] On the contrary, when the locking component is unlocked, the ammonia delivery component can be adjusted up and down on the reactor assembly, and when the ammonia delivery component is adjusted up and down, the ammonia delivery component can slide up and down on the locking component;

[0094] When the ammonia delivery component is adjusted up and down, the use position can be adjusted according to the actual operation needs;

[0095] After the use position adjustment is completed, the ammonia delivery component can be locked and fixed by using the locking component.

Since impurities can also adhere to the inner wall of the kettle body 1, the outer edge of the scraper portion 702 can promptly scrape off the impurities attached to the inner wall of the kettle body 1 when contacting the inner wall of the kettle body 1.

At the same time, each stirring wing rod 703 can perform refined stirring at different height layers of the waste liquid, so that the chemical reaction effect of sulfuric acid and ammonia in the desulfurized waste liquid can be further highlighted.

[0116] Each stirring wing rod 703 is provided with a plurality of through holes 704 , which are evenly distributed along the length direction of the stirring wing rod 703 . The plurality of through holes 704 provided on each stirring wing rod 703 can reduce the resistance of each stirring wing rod 703 in the waste liquid, so that the waste liquid can better pass through the stirring wing rod 703 .

The ammonia filling pipe 10 is hollow inside, with an open top and a closed portion 1002 at the bottom. A plurality of ammonia spray holes 1001 are provided at the lower part of the side wall, and the top end can pass out from the reactor assembly through the insertion hole 203. Conversely, the bottom end of the ammonia filling pipe 10 can also pass through the insertion hole 203 into the reactor assembly.

[0123] Ammonia can be transported to the ammonia filling pipe 10 and injected into the desulfurized waste liquid in the reactor assembly through the ammonia injection hole 1001;

[0124] Since the ammonia filling pipe 10 can pass through the insertion hole 203, the ammonia filling pipe 10 can be adjusted up and down.

[0125] Embodiment 4

[0126] like Figure 1-10 As shown, based on the third embodiment, the following improvements are made:

[0127] Further, such as Figure 2 as well as Figure 7-8 As shown, the locking component includes a sleeve 8 and a hexagon socket set screw 9 mounted on the sleeve 8, wherein the sleeve 8 and the hexagon socket set screw 9 are preferred forms of the locking component;

[0128] The sleeve 8 is fixedly installed on the top of the kettle cover 2 and corresponds to the insertion hole 203. An internal threaded hole 801 is opened on the side wall of the sleeve 8, and the hexagon socket set screw 9 is threadedly installed in the internal threaded hole 801;

[0129] One end of the upper portion of the ammonia filling pipe 10 can be inserted upward into the sleeve 8. After the ammonia filling pipe 10 is inserted, the hexagon socket set screw 9 can clamp and fix the ammonia filling pipe 10 when tightened, thereby limiting the use position of the ammonia filling pipe 10.

[0130] When the hexagon socket set screw 9 is loosened, the ammonia filling pipe 10 can slide upward or downward on the sleeve 8, so that the position of the ammonia filling pipe 10 can be adjusted.

[0131] In summary, the workflow of the utility model is:

[0132] like Figure 1-10 As shown, during the reaction, the motor 4 can drive the rotation of the scraper-type stirring mechanism through the rotation of its output shaft. At this time, the scraper-type stirring mechanism can rotate in the inner cavity of the reactor assembly, and when the scraper-type stirring mechanism rotates, one end of the outer side of the scraper-type stirring mechanism can continuously slide and contact with the inner wall of the reactor body 1 in a rotating manner, and at the same time, the desulfurized waste liquid in the reactor assembly can be uniformly stirred. While the scraper-type stirring mechanism uniformly stirs the desulfurized waste liquid to make it fully react, it can also timely scrape off impurities adhering to the inner wall of the reactor body 1 to prevent impurities from remaining on the inner wall of the reactor body 1;

[0133] An ammonia gas delivery component is movably mounted on the reactor assembly, one end of the ammonia gas delivery component is located in the inner cavity of the reactor body 1, and the other end of the ammonia gas delivery component passes through the reactor cover 2 to the outside;

[0134] Among them, when the desulfurization waste liquid is poured into the reactor assembly, one end of the ammonia gas conveying component is in the liquid of the desulfurization waste liquid;

[0135] Specifically, when the desulfurized waste liquid is stirred by the scraper-type stirring mechanism, it can be added into the desulfurized waste liquid in the reactor assembly through the ammonia delivery component. The delivery of ammonia can be coordinated with the scraper-type stirring mechanism. When the scraper-type stirring mechanism is stirring, ammonia is added into the desulfurized waste liquid at the same time. The ammonia is immersed in the desulfurized waste liquid and can produce a chemical reaction with sulfuric acid in the desulfurized waste liquid.

[0136] When the scraper-type stirring mechanism stirs the desulfurized waste liquid, the chemical reaction between sulfuric acid and ammonia in the desulfurized waste liquid can be accelerated. While accelerating the reaction, the two can also react more fully and generate ammonium sulfate after the reaction. The ammonium sulfate generated by the reaction can be used in agriculture, industry and medicine. After the sulfuric acid and ammonia in the desulfurized waste liquid react chemically, the desulfurized waste liquid can be reused. In a different way, the problem that the discharge of traditional desulfurized waste liquid is prone to cause environmental pollution is solved;

[0137] The locking component is installed on the kettle cover 2 and corresponds to one side of the ammonia gas delivery component. When one end of the ammonia gas delivery component penetrates upward, it can penetrate into the locking component and be locked and fixed by the locking component.

[0138] On the contrary, when the locking component is unlocked, the ammonia delivery component can be adjusted up and down on the reactor assembly, and when the ammonia delivery component is adjusted up and down, the ammonia delivery component can slide up and down on the locking component;

[0139] When the ammonia delivery component is adjusted up and down, the use position can be adjusted according to the actual operation needs;

[0140] After the use position adjustment is completed, the ammonia delivery component can be locked and fixed by using the locking component.

[0141] The above different embodiments can be combined, replaced and used in conjunction with each other.
