Description

Technical Field

[0001] The utility model relates to the technical field of evaporation and purification of waste water, in particular to an ammonium sulfate purification device. 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, certain technical means are usually used to refine the desulfurization waste liquid for multiple times. After multiple refining, ammonium sulfate solution is usually produced as a by-product. As for the ammonium sulfate solution, it is usually purified by evaporation. After purification, the ammonium sulfate aqueous solution is evaporated and crystallized to form ammonium sulfate powder.

[0003] After searching, the Chinese utility model patent with the announcement number CN220345127U discloses an ammonium sulfate evaporation crystallization device, which is used for the evaporation crystallization of ammonium sulfate solution. In the patent, a spiral tube is installed in the reactor body, and the spiral tube passes through the reactor body to connect the air inlet pipe A, and the air inlet pipe A is respectively connected to the air inlet pipe B and the air inlet pipe C, and the air inlet pipe C is connected to the evaporation compressor, and the evaporation compressor is connected to the air outlet pipe E, and the air outlet pipe E is connected to the feed port, and the feed port is fixedly installed on the reactor cover. The middle part of the air outlet pipe E is connected to the air outlet pipe D, and the air outlet pipe D passes through the reactor body to connect the spiral tube.

[0004] Combined with the patent Figure 1-5 As can be seen from the description in paragraph

[0024] of the specification, the heating steam enters the air intake from the air intake pipe B9, passes through the pipe A8 and enters the spiral tube 15 to heat the ammonium sulfate solution.

[0005] It can be seen that in this patent, the ammonium sulfate solution is heated and evaporated by the spiral tube 15 installed in the lower part of the inner cavity of the reactor body 6.

[0006] However, since the spiral tube 15 is installed at the lower part of the inner cavity of the reactor body 6, the heating temperature of the upper and lower layers of the ammonium sulfate solution in the reactor body 6 will be uneven, which will lead to poor effect of heating and purifying the ammonium sulfate solution.

[0007] At the same time, in this patent, Figure 4 As shown, after evaporation and crystallization, the ammonium sulfate solution forms ammonium sulfate powder, which is deposited at the bottom of the inner cavity of the reactor body 6 and is difficult to be effectively discharged through the bottom valve 7.

[0008] Based on this, in order to solve the above technical problems, an ammonium sulfate purification device is now proposed. Utility Model Content

[0009] 1. Technical issues to be resolved

[0010] In view of the deficiencies in the prior art, the utility model provides an ammonium sulfate purification device to solve the following problems proposed in the background technology:

[0011] The Chinese utility model patent with the announcement number CN220345127U discloses an ammonium sulfate evaporation crystallization device. In the patent, since the spiral tube is installed at the lower part of the inner cavity of the reactor body, the heating temperature of the upper and lower layers of the ammonium sulfate solution in the reactor body is uneven, which leads to poor heating and purification effect of the ammonium sulfate solution.

[0012] At the same time, in this patent, after evaporation and crystallization, the ammonium sulfate solution forms ammonium sulfate powder, which is deposited at the bottom of the inner cavity of the reactor body and is difficult to effectively discharge through the bottom valve.

[0036] Beneficial effects:

[0037] The utility model provides an ammonium sulfate purification device, which has the following beneficial effects:

[0038] 1. In the utility model, the high-pressure steam generated by the steam boiler (not shown in the figure) can be transported to the annular steam distribution chamber through the steam pipe. After the high-pressure steam enters the annular steam distribution chamber, it can enter each one-way steam nozzle at the same time. Since each one-way steam nozzle is distributed from top to bottom on the side wall of the evaporation inner tank in a circular form, the high-pressure steam can be sprayed in a cross manner at different height layers in the inner cavity of the evaporation inner tank at the same time. When the high-pressure steam is sprayed in a cross manner at different height layers in the inner cavity of the evaporation inner tank, different height layers of the ammonium sulfate solution in the evaporation inner tank can be evaporated and purified at the same temperature, thereby improving the purification effect of the ammonium sulfate solution.

[0039] 2. In the utility model, while the high-pressure steam is evaporating and purifying the ammonium sulfate solution, the motor can drive the scraper and stirring assembly through its output shaft, so that the scraper and stirring assembly rotates at a high speed in the inner cavity of the evaporation inner tank. When the scraper and stirring assembly rotates at a high speed, the ammonium sulfate solution being evaporated and purified can be stirred, and while the scraper and stirring assembly is stirring, it can also continuously scrape the material at the bottom of the inner cavity of the evaporation inner tank.

[0040] 3. In the utility model, after the purification is completed, the ammonium sulfate solution will crystallize and form ammonium sulfate powder. After the ammonium sulfate solution forms ammonium sulfate powder after evaporation and purification, the discharge valve on each discharge pipe is opened at the same time, so that each discharge valve remains in an open state. At this time, the scraper and stirring assembly continues to rotate at a high speed driven by the output shaft of the motor. Since the scraper and stirring assembly can continuously scrape the bottom of the inner cavity of the evaporator inner tank, the ammonium sulfate powder at the bottom of the inner cavity of the evaporator inner tank can be scraped by the scraper and stirring assembly to each discharge pipe and discharged through the discharge pipe. Under the scraping action of the scraper and stirring assembly, the discharge speed and efficiency of the purification device can be improved.

[0041] 4. In the utility model, while the high-pressure steam is purifying the ammonium sulfate solution, in order to avoid the waste of heat of the high-pressure steam, the high-pressure steam in the evaporation inner tank will enter the steam recovery pipe through the exhaust pipe, then enter the water tank air inlet pipe through the steam recovery pipe, and then enter the water tank through the water tank air inlet pipe. When the high-pressure steam enters the water tank, it can heat the water in the water tank. After the water in the water tank is heated by the high-pressure steam, it can be used in other processes in the workshop. The high-pressure steam enters the water tank from the inner cavity of the evaporation inner tank and heats the water in the water tank. This process realizes the secondary utilization of the high-pressure steam and avoids the waste of heat energy.

[0042] 5. In the present invention, when one end of the bottom of each L-shaped stirring frame is in sliding contact with the bottom of the inner cavity of the evaporation inner tank, it is possible to prevent crystallized ammonium sulfate from being deposited on the bottom of the inner cavity of the evaporation inner tank.

[0043] 6. In the utility model, under the action of each through hole, the stirring arm of each L-shaped stirring frame can rotate more smoothly in the ammonium sulfate solution.

[0044] 7. In the utility model, each scraper claw can play the role of scraping, and when unloading, each scraper claw can scrape the ammonium sulfate powder at the bottom of the inner cavity of the evaporator to the discharge pipe when rotating at high speed, so as to accelerate the unloading speed of the purification device. At the same time, it can also avoid the situation where the ammonium sulfate powder cannot be discharged due to being deposited at the bottom of the inner cavity of the evaporator.

[0045] 8. In the utility model, each scraper claw has an arc-shaped bending portion at one end of its outer side, and the outer arc surface of each arc-shaped bending portion can fit with the inner arc surface of the circular arc portion, and after fitting, the outer arc surface of each arc-shaped bending portion can slide in contact with the inner arc surface of the circular arc portion. Since each discharge pipe is installed at the circular arc portion, each arc-shaped bending portion can better assist in unloading, thereby further improving the unloading efficiency of the ammonium sulfate powder in the evaporation inner tank.

DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0056] Embodiment 1

[0057] like Figure 1-8 As shown, the utility model provides a technical solution:

[0058] An ammonium sulfate purification device, comprising:

[0059] The evaporation tank body assembly 10 includes an evaporation inner tank 1001 and a steam outer tank 1002;

[0060] A feed pipe 10011 is provided on one side of the top of the evaporation inner tank 1001, and a plurality of discharge pipes 10012 are provided at the bottom edge of the evaporation inner tank 1001, and a discharge valve 20 is installed on each discharge pipe 10012;

[0061] A plurality of embedding holes 10014 are provided on the side wall of the evaporation inner tank 1001. The plurality of embedding holes 10014 are distributed in a circumferential manner from top to bottom on the side wall of the evaporation inner tank 1001.

[0062] An exhaust pipe 10015 is provided on one side of the top of the evaporation inner tank 1001;

[0063] The steam outer tank 1002 is fixedly mounted on the outer wall of the evaporation inner tank 1001. A steam inlet pipe 10021 is provided on one side of the top of the steam outer tank 1002. An annular steam distribution chamber 10022 is formed between the steam outer tank 1002 and the evaporation inner tank 1001.

[0064] The annular steam distribution chamber 10022 is connected to the inner cavity of the evaporation inner tank 1001 through the embedding hole 10014;

[0065] The motor 30 is fixedly mounted at the top center of the evaporator inner tank 1001, and the output shaft of the motor 30 passes downward from the top of the evaporator inner tank 1001 and extends into the inner cavity of the evaporator inner tank 1001;

[0066] The scraper and stirrer assembly 40 is rotatably mounted in the inner cavity of the evaporator inner tank 1001, and one end of the top of the scraper and stirrer assembly 40 is connected to the output shaft of the motor 30;

[0067] A plurality of one-way steam nozzles 50, each of which can correspond to the embedding hole 10014 one by one, and each of which is embedded in the corresponding embedding hole 10014, and after embedding, the air inlet end of each one-way steam nozzle 50 is located in the annular steam distribution chamber 10022, and the jet end of each one-way steam nozzle 50 is located in the inner cavity of the evaporation inner tank 1001;

[0068] A water tank 60, which is disposed on one side of the evaporation tank assembly 10, and has a water tank air inlet pipe 6001 on the top of the water tank 60;

[0069] The water tank 60 is filled with water, and a drain pipe (not shown) with a valve is provided on one side of the bottom of the water tank 60. The water in the water tank 60 can be used by opening the valve of the drain pipe.

[0070] In addition, the water tank 60 also has a pressure relief exhaust port (not shown in the figure), which is used for pressure relief and exhaust when the water tank 60 is working; and a steam recovery pipe 70, one end of the steam recovery pipe 70 is plugged into the exhaust pipe 10015, and the other end of the steam recovery pipe 70 is plugged into the water tank air inlet pipe 6001.

[0071] In this embodiment, one end of the discharge pipe (not shown in the figure) of the ammonium sulfate solution can be plugged into the feed pipe 10011. At the same time, the steam boiler (not shown in the figure) can be arranged on one side of the evaporation tank assembly 10. The steam boiler has a steam pipe (not shown in the figure). One end of the steam pipe is connected to the steam boiler, and the other end can be plugged into the steam inlet pipe 10021 and connected to the steam outer tank 1002 in the evaporation tank assembly 10.

[0072] Among them, the ammonium sulfate solution can be poured into the evaporation inner tank 1001 through the discharge pipe of the ammonium sulfate solution. After the pouring is completed, the high-pressure steam generated by the steam boiler can be transported to the annular steam distribution chamber 10022 through the steam pipeline. After the high-pressure steam enters the annular steam distribution chamber 10022, it can simultaneously enter each one-way steam nozzle 50. Since each one-way steam nozzle 50 is distributed from top to bottom on the side wall of the evaporation inner tank 1001 in a circular form, the high-pressure steam can be sprayed in a cross manner at different height layers in the inner cavity of the evaporation inner tank 1001. When the high-pressure steam is sprayed in a cross manner at different height layers in the inner cavity of the evaporation inner tank 1001, different height layers of the ammonium sulfate solution in the evaporation inner tank 1001 can be evaporated and purified at the same temperature, thereby improving the purification effect of the ammonium sulfate solution;

[0073] At the same time, while the high-pressure steam is evaporating and purifying the ammonium sulfate solution, the motor 30 can drive the scraper and stirrer assembly 40 through its output shaft, so that the scraper and stirrer assembly 40 rotates at a high speed in the inner cavity of the evaporation inner tank 1001. When the scraper and stirrer assembly 40 rotates at a high speed, the ammonium sulfate solution being evaporated and purified can be stirred, and while the scraper and stirrer assembly 40 is stirring, the material can also be continuously scraped at the bottom of the inner cavity of the evaporation inner tank 1001;

[0074] After the purification is completed, the ammonium sulfate solution will crystallize and form ammonium sulfate powder. After the ammonium sulfate solution forms ammonium sulfate powder after evaporation and purification, the discharge valve 20 on each discharge pipe 10012 is opened at the same time, so that each discharge valve 20 remains in an open state. At this time, the scraper and stirring assembly 40 continues to rotate at a high speed driven by the output shaft of the motor 30. Since the scraper and stirring assembly 40 can continuously scrape the bottom of the inner cavity of the evaporator inner tank 1001, the ammonium sulfate powder at the bottom of the inner cavity of the evaporator inner tank 1001 can be scraped by the scraper and stirring assembly 40 to each discharge pipe 10012, and discharged through the discharge pipe 10012. Under the scraping action of the scraper and stirring assembly 40, the discharge speed and efficiency of the purification device can be improved;

[0075] While the high-pressure steam is purifying the ammonium sulfate solution, in order to avoid heat waste of the high-pressure steam, the high-pressure steam in the evaporator inner tank 1001 will enter the steam recovery pipe 70 through the exhaust pipe 10015, and then enter the water tank air inlet pipe 6001 through the steam recovery pipe 70, and then enter the water tank 60 through the water tank air inlet pipe 6001. When the high-pressure steam enters the water tank 60, it can heat the water in the water tank 60. After being heated by the high-pressure steam, the water in the water tank 60 can be used in other processes in the workshop. The high-pressure steam enters the water tank 60 from the inner cavity of the evaporator inner tank 1001 and heats the water in the water tank 60. This process realizes the secondary utilization of the high-pressure steam and avoids the waste of heat energy.

[0076] Embodiment 2

[0077] like Figure 1-8 As shown, based on the first embodiment, the following improvements are made:

[0078] Furthermore, an axial hole 10013 is provided at the center of the bottom of the inner cavity of the evaporation inner tank 1001;

[0079] The scraper stirring assembly 40 includes a main shaft 4001, the bottom of the main shaft 4001 has an assembly end 40011, the assembly end 40011 is rotatably mounted in the shaft hole 10013, and the top end of the main shaft 4001 is fixedly connected to the output shaft end of the motor 30;

[0080] A shaft sleeve 4002 is fixedly installed at one end of the bottom of the main shaft 4001, and a plurality of L-shaped stirring racks 4003 are fixedly installed on the side wall of the shaft sleeve 4002. The plurality of L-shaped stirring racks 4003 are distributed circumferentially on the side wall of the shaft sleeve 4002;

[0081] Among them, one bottom end of the shaft sleeve 4002 can slide in contact with the bottom of the inner cavity of the evaporation inner tank 1001 , and one bottom end of each L-shaped stirring frame 4003 can slide in contact with the bottom of the inner cavity of the evaporation inner tank 1001 .

[0082] In this embodiment, the above is a preferred structure of the scraper stirring assembly 40. The main shaft 4001 can be driven by the output shaft of the motor 30 and rotate at a high speed in the inner cavity of the evaporation inner tank 1001. When the main shaft 4001 rotates at a high speed, it can drive the shaft sleeve 4002 to rotate at a high speed. When the shaft sleeve 4002 rotates at a high speed, it can simultaneously drive multiple L-shaped stirring racks 4003. When the multiple L-shaped stirring racks 4003 rotate at a high speed, the ammonium sulfate solution being evaporated and purified can be stirred.

[0083] Furthermore, when one end of the bottom of each L-shaped stirring frame 4003 is in sliding contact with the bottom of the inner cavity of the evaporation inner tank 1001 , it is possible to prevent crystallized ammonium sulfate from being deposited on the bottom of the inner cavity of the evaporation inner tank 1001 .

[0084] Furthermore, each L-shaped stirring rack 4003 has a stirring arm on the top, and each stirring arm is provided with a plurality of through holes 40031. With the action of each through hole 40031, the stirring arm of each L-shaped stirring rack 4003 can rotate more smoothly in the ammonium sulfate solution.

[0085] Furthermore, a scraper claw 4004 is fixedly mounted on the bottom of the side wall of each L-shaped stirring frame 4003 , and the bottom of each scraper claw 4004 can be in sliding contact with the bottom of the inner cavity of the evaporation inner tank 1001 .

[0086] In this embodiment, each scraper claw 4004 can play the role of scraping, and during unloading, each scraper claw 4004 can scrape the ammonium sulfate powder at the bottom of the inner cavity of the evaporator inner tank 1001 to the discharge pipe 10012 when rotating at a high speed, so as to accelerate the unloading speed of the purification device. At the same time, it can also avoid the situation where the ammonium sulfate powder cannot be discharged due to being deposited at the bottom of the inner cavity of the evaporator inner tank 1001.

[0087] Furthermore, the bottom edge of the evaporation inner tank 1001 has a circular arc portion 10016;

[0088] Each scraper claw 4004 has an arc-shaped bending portion 40041 at one end of its outer side, and the outer arc surface of each arc-shaped bending portion 40041 can fit with the inner arc surface of the circular arc portion 10016, and after fitting, the outer arc surface of each arc-shaped bending portion 40041 can slide in contact with the inner arc surface of the circular arc portion 10016. Since each discharge pipe 10012 is installed at the circular arc portion 10016, each arc-shaped bending portion 40041 can better assist in unloading, thereby further improving the unloading efficiency of the ammonium sulfate powder in the evaporation inner tank 1001.

[0089] Specifically, after each one-way steam nozzle 50 is embedded in the corresponding embedding hole 10014, each one-way steam nozzle 50 is interference fit with the corresponding embedding hole 10014, so there is no gap between the two, thereby preventing the ammonium sulfate solvent in the evaporation purification from leaking through the gap between the one-way steam nozzle 50 and the embedding hole 10014.

[0090] Furthermore, each discharge pipe 10012 is located at the arc portion 10016, each discharge pipe 10012 is inclined, and the bottom opening of each discharge pipe 10012 is inclined downward. Due to the inclined setting of each discharge pipe 10012, the unloading of ammonium sulfate powder can be more convenient.

[0091] In summary, the workflow of the utility model is:

[0092] like Figure 1-8As shown, one end of the discharge pipe (not shown in the figure) of the ammonium sulfate solution can be plugged and installed in the feed pipe 10011. At the same time, the steam boiler (not shown in the figure) can be arranged on one side of the evaporation tank assembly 10. The steam boiler has a steam pipe (not shown in the figure). One end of the steam pipe is connected to the steam boiler, and the other end can be plugged into the steam inlet pipe 10021 and connected to the steam outer tank 1002 in the evaporation tank assembly 10.

[0093] Among them, the ammonium sulfate solution can be poured into the evaporation inner tank 1001 through the discharge pipe of the ammonium sulfate solution. After the pouring is completed, the high-pressure steam generated by the steam boiler can be transported to the annular steam distribution chamber 10022 through the steam pipeline. After the high-pressure steam enters the annular steam distribution chamber 10022, it can simultaneously enter each one-way steam nozzle 50. Since each one-way steam nozzle 50 is distributed from top to bottom on the side wall of the evaporation inner tank 1001 in a circular form, the high-pressure steam can be sprayed in a cross manner at different height layers in the inner cavity of the evaporation inner tank 1001. When the high-pressure steam is sprayed in a cross manner at different height layers in the inner cavity of the evaporation inner tank 1001, different height layers of the ammonium sulfate solution in the evaporation inner tank 1001 can be evaporated and purified at the same temperature, thereby improving the purification effect of the ammonium sulfate solution;

[0094] At the same time, while the high-pressure steam is evaporating and purifying the ammonium sulfate solution, the motor 30 can drive the scraper and stirrer assembly 40 through its output shaft, so that the scraper and stirrer assembly 40 rotates at a high speed in the inner cavity of the evaporation inner tank 1001. When the scraper and stirrer assembly 40 rotates at a high speed, the ammonium sulfate solution being evaporated and purified can be stirred, and while the scraper and stirrer assembly 40 is stirring, the material can also be continuously scraped at the bottom of the inner cavity of the evaporation inner tank 1001;

[0095] After the purification is completed, the ammonium sulfate solution will crystallize and form ammonium sulfate powder. After the ammonium sulfate solution forms ammonium sulfate powder after evaporation and purification, the discharge valve 20 on each discharge pipe 10012 is opened at the same time, so that each discharge valve 20 remains in an open state. At this time, the scraper and stirring assembly 40 continues to rotate at a high speed driven by the output shaft of the motor 30. Since the scraper and stirring assembly 40 can continuously scrape the bottom of the inner cavity of the evaporator inner tank 1001, the ammonium sulfate powder at the bottom of the inner cavity of the evaporator inner tank 1001 can be scraped by the scraper and stirring assembly 40 to each discharge pipe 10012, and discharged through the discharge pipe 10012. Under the scraping action of the scraper and stirring assembly 40, the discharge speed and efficiency of the purification device can be improved;

[0096] While the high-pressure steam is purifying the ammonium sulfate solution, in order to avoid heat waste of the high-pressure steam, the high-pressure steam in the evaporator inner tank 1001 will enter the steam recovery pipe 70 through the exhaust pipe 10015, and then enter the water tank air inlet pipe 6001 through the steam recovery pipe 70, and then enter the water tank 60 through the water tank air inlet pipe 6001. When the high-pressure steam enters the water tank 60, it can heat the water in the water tank 60. After being heated by the high-pressure steam, the water in the water tank 60 can be used in other processes in the workshop. The high-pressure steam enters the water tank 60 from the inner cavity of the evaporator inner tank 1001 and heats the water in the water tank 60. This process realizes the secondary utilization of the high-pressure steam and avoids the waste of heat energy.

[0097] During the stirring process, specifically: the main shaft 4001 can be driven by the output shaft of the motor 30 to rotate at a high speed in the inner cavity of the evaporation inner tank 1001. When the main shaft 4001 rotates at a high speed, it can drive the shaft sleeve 4002 to rotate at a high speed. When the shaft sleeve 4002 rotates at a high speed, it can simultaneously drive multiple L-shaped stirring racks 4003. When the multiple L-shaped stirring racks 4003 rotate at a high speed, the ammonium sulfate solution being evaporated and purified can be stirred;

[0098] Furthermore, when one end of the bottom of each L-shaped stirring frame 4003 is in sliding contact with the bottom of the inner cavity of the evaporation inner tank 1001, it is possible to prevent the crystallized ammonium sulfate from being deposited on the bottom of the inner cavity of the evaporation inner tank 1001;

[0099] Under the action of each through hole 40031, the stirring arm of each L-shaped stirring frame 4003 can rotate more smoothly in the ammonium sulfate solution;

[0100] Each scraper claw 4004 can play the role of scraping, and when discharging, each scraper claw 4004 can scrape the ammonium sulfate powder at the bottom of the inner cavity of the evaporation inner tank 1001 to the discharge pipe 10012 when rotating at a high speed, so as to accelerate the discharging speed of the purification device, and at the same time, it can also avoid the situation that the ammonium sulfate powder cannot be discharged due to being deposited at the bottom of the inner cavity of the evaporation inner tank 1001;

[0101] Each scraper claw 4004 has an arc-shaped bending portion 40041 at one end of its outer side, and the outer arc surface of each arc-shaped bending portion 40041 can fit with the inner arc surface of the circular arc portion 10016, and after fitting, the outer arc surface of each arc-shaped bending portion 40041 can slide in contact with the inner arc surface of the circular arc portion 10016. Since each discharge pipe 10012 is installed at the circular arc portion 10016, each arc-shaped bending portion 40041 can better assist in unloading, thereby further improving the unloading efficiency of the ammonium sulfate powder in the evaporation inner tank 1001.

[0102] The above different embodiments can be combined, replaced and used in conjunction with each other.
