[0002] As environmental protection requirements become increasingly stringent, the soda ash industry is faced with the common and thorny problem of ammonia gas overflow during the transportation of wet ammonium. This problem not only has a negative impact on the environment, but also becomes a bottleneck in the development of the industry. Solutions are urgently needed to promote the sustainable development of the industry.

[0003] At present, roller belt conveyors are mostly used to transport wet ammonium. To address the problem of ammonia overflow during the transportation process, it is common to add draft hoods in areas where ammonia overflow is more serious to collect ammonia-containing gas and reduce its direct emission to the surrounding environment.

[0004] Although the method of collecting ammonia-containing gas with induced draft hoods can alleviate ammonia overflow to a certain extent, due to its open structural design, the overflow problem of ammonia-containing gas is still serious when transporting wet ammonium chloride, causing continuous pollution to the surrounding environment and failing to achieve the ideal environmental protection effect. It is urgently needed to replace it with more efficient and environmentally friendly technologies and equipment. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] The embodiment of the present application provides a wet ammonium gas suspension conveying device and a control method, which solves the problem of serious overflow of ammonia-containing gas during the conveyance of wet ammonium chloride, causing continuous pollution to the surrounding environment, and realizes safe and environmentally friendly conveyance of wet ammonium chloride.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figure 1 and Figure 2 As shown, a wet ammonium gas suspension conveying device provided in an embodiment of the present application includes a conveyor belt 2, a conveying pipeline and a tray 13;

[0040] The conveyor belt 2 passes through the conveying pipeline, and the conveyor belt 2 is used to convey materials;

[0041] The tray 13 is installed in the conveying pipeline to divide the conveying pipeline into a conveying cavity and an air chamber 12. The tray 13 is arranged below the conveying belt 2. Figure 3 As shown, the tray 13 is provided with a plurality of air holes 17, and the air holes 17 respectively connect the conveying cavity with the air chamber 12, the air chamber 12 is used to connect with the blower 9, and the conveying cavity is used to connect with the induced draft fan (not shown in the figure).

[0042] In the present embodiment, conveyor belt 2 passes through a delivery pipeline, and wet ammonium (ammonium chloride) is placed on conveyor belt 2. When conveyor belt 2 is running, wet ammonium is in a delivery pipeline of a fully enclosed state. During transportation, wet ammonium can shake and collide along with the motion of transportation equipment. For example, on conveyor belt 2, wet ammonium particles rub and collide with each other, so that the adsorbed water and crystal water on the surface of ammonium chloride crystals are stirred, destroying the original equilibrium state of ammonium radical ions in solution, promoting more ammonium radical ions to hydrolyze, and then generating ammonia. When conveyor belt 2 is running, blower 9 works synchronously, and air is constantly ejected from air chamber 12 through pore 17, and the ejected air enters between conveyor belt 2 and pallet 13, and an air film is formed between the two, and the air film supports conveyor belt 2 and the material thereon, reduces the friction between conveyor belt 2 and pallet 13, improves the stability of conveyor belt 2 operation, and prolongs the service life of conveyor belt 2. Meanwhile, the air between conveyor belt 2 and pallet 13 overflows from conveyor belt 2 both sides, and the ammonia gas of blast air and wet ammonium volatilization gathers in the delivery pipeline. The induced draft fan works to divert the ammonia-containing gas in the conveying pipeline to the next process for treatment (such as the waste gas treatment device), greatly reducing the probability of the ammonia-containing gas diffusing into the external environment and achieving safe and environmentally friendly transportation of wet ammonium chloride.

[0043] In an optional embodiment of the present application, Figure 2 and Figure 4 As shown, the conveying pipeline includes: a first support frame 5, a first cover plate 6, a second support frame 7 and a second cover plate 8; the first cover plate 6 is installed on the first support frame 5 to form a first conveying pipeline; the second cover plate 8 is installed on the second support frame 7 to form a second conveying pipeline; the first support frame 5 is connected to the second support frame 7, the first cover plate 6 is connected to the second cover plate 8, and the first conveying pipeline is connected to the second conveying pipeline; the conveyor belt 2 passes through the first conveying pipeline and the second conveying pipeline. In addition, Figure 2 As shown, one or more air inlets may be provided on the top of the second cover plate 8, and one or more air inlets may be further provided on the first cover plate 6, and the draft fan is connected to the air inlets, thereby communicating with the conveying pipeline.

[0044] Specifically, Figure 4 The first cover plate 6 is assembled with the first support frame 5 to form a first delivery pipeline. Figure 2The second cover plate 8 is spliced ​​with the second support frame 7 to form a second conveying pipeline. The first conveying pipeline and the second conveying pipeline are similar to fully enclosed pipelines. The conveyor belt 2 passes through the first conveying pipeline and the second conveying pipeline. Wet ammonium (ammonium chloride) is placed on the conveyor belt 2. When the conveyor belt 2 is running, the wet ammonium is in a fully enclosed conveying pipeline. At the same time, the induced draft fan works to divert the ammonia-containing gas in the first conveying pipeline and the ammonia-containing gas in the second conveying pipeline to the next process for treatment (such as a waste gas treatment device), which greatly reduces the diffusion of overflowed ammonia-containing gas into the external environment, thereby realizing safe and environmentally friendly transportation of wet ammonium chloride. The conveying pipeline is formed by splicing the first conveying pipeline and the second conveying pipeline, and can also be designed to be spliced ​​by multiple sections. The cross-sectional shapes of the first conveying pipeline and the second conveying pipeline can be different, for example Figure 2 and Figure 4 As shown, the cross-sectional area of ​​the first conveying pipeline is relatively large in order to facilitate the subsequent installation of the discharge chute 4 and the guide plate 16.

[0045] In an optional embodiment of the present application, Figure 2 and Figure 4 As shown, the tray 13 is installed on the first support frame 5 and the second support frame 7, the tray 13 divides the first conveying pipe into a first conveying cavity 14 and a part of the air chamber 12, and the tray 13 divides the second conveying pipe into a second conveying cavity 15 and another part of the air chamber 12, and a part of the air chamber 12 in the first conveying pipe and another part of the air chamber 12 in the second conveying pipe together constitute a complete air chamber 12. The air holes 17 connect the first conveying cavity 14 and the second conveying cavity 15 with the air chamber 12 respectively.

[0046] Specifically, Figure 2 As shown, the cross section of the tray 13 is a concave arc, and the conveyor belt 2 is laid on the tray 13. When the conveyed material is placed on the conveyor belt 2, the conveyor belt 2 also presents an arc, so that the material gathers in the middle of the conveyor belt 2. During the conveying process, the material is not easy to spill from both sides. When the conveyor belt 2 is running, the blower 9 works synchronously, and the air is continuously ejected from the air chamber 12 through the air hole 17. The ejected air enters between the conveyor belt 2 and the tray 13, and an air film is formed between the two. The air film supports the conveyor belt 2 and the material thereon, reduces the friction between the conveyor belt 2 and the tray 13, improves the stability of the conveyor belt 2, and extends the service life of the conveyor belt 2. In addition, the air induced capacity of the induced draft fan is greater than the air supply capacity of the blower 9, and the conveyor belt 2 is in a slightly negative pressure state, which increases the speed of the ammonia-containing gas to be drained to the next processing step, and further reduces the emission of pollutants such as ammonia-containing gas and dust from the conveying pipeline. The blower 9 can be installed at one end of the first conveying pipeline away from the second conveying pipeline, or at one end of the second conveying pipeline away from the first conveying pipeline, or at the middle of the main pipeline composed of the first conveying pipeline and the second conveying pipeline.

[0047] In an optional embodiment of the present application, Figure 4 As shown, the wet ammonium gas suspension conveying device also includes support rods 18, and a plurality of the support rods 18 are respectively installed in the first support frame 5 and the second support frame 7, and the support rods 18 are located in the air chamber 12 for supporting the tray 13.

[0048] Specifically, the support rod 18 is used to support the tray 13 to prevent the tray 13 from being deformed due to long-term use. In addition, the support rod 18 supports the tray 13, which can also reduce the running vibration of the tray 13, thereby reducing the ammonia gas overflowing from the wet ammonium. Figure 2 and Figure 4 As shown, support rods 18 are symmetrically installed in the first support frame 5 and the second support frame 7 respectively.

[0049] In an optional embodiment of the present application, Figure 4 As shown, the first cover plate 6 includes a side plate 10 and a top cover 11, the side plate 10 is installed on the first support frame 5, and the top cover 11 is installed on the side plate 10, and the first support frame 5, the side plate 10 and the top cover 11 are combined into the first conveying pipeline.

[0050] Specifically, Figure 4 The first cover plate 6 is composed of two side plates 10 and a top cover 11. The two side plates 10 are installed on both sides of the top cover 11 and then installed on the first support frame 5, which is convenient for production, transportation and assembly.

[0051] In an optional embodiment of the present application, Figure 4 As shown, the wet ammonium gas suspension conveying device also includes a discharge chute 4 and a guide plate 16. The discharge chute 4 is installed on the top cover 11. The discharge chute 4 is connected to the first conveying pipeline. The guide plates 16 are arranged on both sides of the discharge chute 4. The guide plates 16 are installed on the side of the top cover 11 close to the air chamber 12.

[0052] Specifically, a mounting port can be opened on the top cover 11, and the material discharge chute 4 can be passed through the top cover 11 and mounted on the mounting port of the top cover 11, and materials can be put in from the upper port of the material discharge chute 4. In order to prevent the materials from being scattered to the edge of the conveyor belt 2, guide plates 16 mounted on the top cover 11 are arranged on both sides of the material discharge chute 4. The guide plates 16 guide the materials to fall to the middle of the conveyor belt 2 and prevent the materials from being scattered to the edge of the conveyor belt 2. In addition, the bottom of the material discharge chute 4 is arranged in an arc shape, and the two sides of the bottom of the material discharge chute 4 are close to the conveyor belt 2 relative to the middle part. Such a design can also further guide the materials to be concentrated in the middle of the conveyor belt 2.

[0053] In an optional embodiment of the present application, the wet ammonium gas suspension conveying device also includes an air pressure sensor 19 (not shown in the figure), and the air pressure sensor 19 is installed on the second support frame 7. The air pressure sensor 19 is used to detect the air pressure in the air chamber 12 in the second conveying pipeline.

[0054] Specifically, in order to ensure that a stable air film can be formed between the conveyor belt 2 and the pallet 13, and to support the conveyor belt 2 to suspend and run on the pallet 13, it is necessary to ensure that the air pressure in the air chamber 12 is greater than the starting air pressure, which is the minimum air pressure value that can support the conveyor belt 2 to suspend on the pallet 13. In order to monitor the air pressure value in the air chamber 12, an air pressure sensor 19 is provided to detect the air pressure of the air chamber 12 in the second conveying pipeline. The air pressure sensor 19 is preferably installed at one end of the second conveying pipeline away from the blower 9. In this way, when monitoring the air pressure, when the air pressure at a position away from the blower 9 is greater than the starting air pressure, the air pressure at a position near the blower 9 can also meet the requirement of being greater than the starting air pressure.

[0055] In an optional embodiment of the present application, Figure 1 and Figure 5 As shown, the wet ammonium gas suspension conveying device also includes a bracket 1 and a support roller 3. The support roller 3 is installed on the bracket 1, and the conveyor belt 2 is laid on the support roller 3.

[0056] Specifically, the support rollers 3 can support and guide the conveyor belt 2 at both ends to smoothly enter the first conveying pipe and the second conveying pipe, reduce the friction between the conveyor belt 2 and the ends of the conveying pipes, and increase the service life of the conveyor belt 2.

[0057] In an optional embodiment of the present application, deviation sensors (not shown in the figure) are provided on both sides of the conveyor belt 2 , and the deviation sensors can be installed on the bracket 1 .

[0058] Specifically, the deviation sensor can be installed on the bracket 1 on both sides of the support roller 3, so that it can monitor whether the conveyor belt 2 deviates when entering and leaving the conveying pipeline. When both ends of the conveyor belt 2 do not deviate, the middle part of the conveyor belt 2 is unlikely to deviate. Furthermore, a deviation sensor can also be added in the middle of the length direction of the conveyor belt 2 to better monitor the operation of the conveyor belt 2.

[0059] Based on the above wet ammonium gas suspension conveying device, an embodiment of the present application provides a control method for the wet ammonium gas suspension conveying device, including:

[0060] Start the blower 9. When the detection value of the air pressure sensor is greater than or equal to the starting pressure value, it means that an air film is formed between the conveyor belt 2 and the pallet 13 to support the conveyor belt 2 to suspend and run. At this time, the drive of the conveyor belt can be controlled to start, such as controlling the rotation of the conveyor belt roller motor. When the detection value of the air pressure sensor is less than the starting pressure value, it means that the air pressure is insufficient to lift the conveyor belt 2. If it continues to run, the conveyor belt 2 will fit the pallet 13, and the friction damage of the conveyor belt 2 will be greater. At this time, the drive of the conveyor belt can be controlled to stop, such as stopping the conveyor belt roller motor. After that, the working efficiency of the blower 9 can be increased or maintenance can be carried out.

[0061] In addition, when the deviation sensor triggers the first-level signal, an early warning is issued; when the deviation sensor triggers the second-level signal, the driving part of the conveyor belt is controlled to stop. Specifically, the deviation sensor can be set to two-level triggering, and the first-level signal and the second-level signal are generated after the two-level triggering respectively. When the first-level signal is triggered, it means that the conveyor belt 2 is slightly offset. At this time, an early warning is issued, and attention should be paid to the subsequent operation status of the conveyor belt 2; when the second-level signal is triggered, it means that the conveyor belt 2 has a large offset, and it is necessary to stop the conveyor belt 2 for maintenance and adjustment. Through the air pressure sensor and the deviation sensor, the air pressure in the air chamber 12 and the position of the conveyor belt 2 are monitored in real time, respectively, so that the problems of low pressure in the air chamber 12 and deviation of the conveyor belt 2 can be discovered in time, so as to avoid the device from running in a bad state and ensure the safety and stability of the operation of the entire conveying device.

[0062] It should be noted that the above-mentioned conveyor belt 2, blower 9 and induced draft fan can be remotely controlled, and the operating voltage, current and other signals of these devices can be further collected, assisted by cameras and other equipment to improve the intelligence level of the system.

[0063] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0064] 1. When the conveyor belt 2 is running, the wet ammonium is in a fully enclosed conveying pipeline, and the induced draft fan guides the ammonia-containing gas in the first conveying pipeline and the ammonia-containing gas in the second conveying pipeline to the next process for treatment, thereby reducing the probability of the ammonia-containing gas diffusing into the external environment and realizing the safe and environmentally friendly transportation of wet ammonium chloride.

[0065] 2. When the conveyor belt 2 is running, the blower 9 works synchronously to form an air film between the conveyor belt 2 and the pallet 13. The air film supports the conveyor belt 2 and the materials thereon, reduces the friction between the conveyor belt 2 and the pallet 13, improves the stability of the conveyor belt 2, and extends the service life of the conveyor belt 2.

[0066] 3. The air pressure sensor and the deviation sensor are used to monitor the air pressure in the air chamber 12 and the position of the conveyor belt 2 in real time, so that the problems of low pressure in the air chamber 12 and deviation of the conveyor belt 2 can be discovered in time, avoiding the operation of the device in a bad state and ensuring the safety and stability of the operation of the entire conveying device.

[0067] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
