Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, specifically to a separation device for the crystallization of desulfurized gypsum. Background Technology
[0002] Desulfurization gypsum production is a process that desulfurizes sulfur-containing gases produced by coal combustion and generates desulfurized gypsum. In the environmental protection field, desulfurization gypsum production plays a crucial role, effectively reducing the environmental impact of sulfur-containing gases from coal combustion. Waste gas desulfurization is a critical step in the desulfurization gypsum production process. Waste gas desulfurization refers to the process of removing sulfur from sulfur-containing gases using specific technologies. Currently, widely used waste gas desulfurization technologies include dry desulfurization, wet desulfurization, and semi-dry desulfurization. Among these, wet desulfurization is a commonly used waste gas desulfurization technology. First, sulfur dioxide is absorbed. This step is mainly completed in an absorption tower, where limestone powder mixed with water forms a slurry, which is used as the absorbent and thoroughly mixed with the flue gas. The sulfur dioxide in the flue gas reacts with calcium hydroxide in the slurry and air blown in from the bottom of the tower to produce calcium sulfate, calcium sulfite, and water.
[0003] The existing technology has the following problems:
[0004] 1. Existing separation devices for the crystallization of desulfurized gypsum require the device to remain still during the addition of chemicals, and the gas emissions during the reaction cannot be collected, which can easily cause air pollution.
[0005] 2. Existing separation devices for desulfurized gypsum crystallization have large rotation amplitudes during the desulfurization process, resulting in unstable operation, poor desulfurization effect, and slow desulfurization speed. Utility Model Content

[0022] The present invention will be further described in detail below with reference to embodiments:
[0023] Example 1
[0024] like Figure 1-4As shown, this utility model provides a separation device for the crystallization of desulfurized gypsum, including an outer cylinder 1, a barrel cover 2 movably connected to the top of the outer cylinder 1, a feed pipe 3 fixedly connected to the top of the barrel cover 2, a rotating motor 4 fixedly connected to the bottom of the outer cylinder 1, a separation cylinder 6 movably connected to the top of the rotating motor 4, a support platform 5 inserted into the bottom of the separation cylinder 6, a liquid filling device 7 fixedly installed on the outer wall of the outer cylinder 1, the liquid filling device 7 including a connecting rod 71, a discharge device 8 fixedly connected to the bottom of the support platform 5, the discharge device 8 including a crystal outlet pipe 81, a support column 9 fixedly connected to the bottom of the outer cylinder 1, and a drain pipe 10 fixedly connected to the bottom of the outer cylinder 1.
[0025] One end of the crystal outlet tube 81 passes through one side of the outer cylinder 1 and is fixedly connected to a discharge valve 82, while the other end of the discharge valve 82 is inserted into the bottom of the support platform 5.
[0026] In this implementation case, the combined action of the outer cylinder 1, the lid 2, the feed pipe 3, the rotating motor 4, and the separation cylinder 6 makes the device more convenient to use. The lid 2 is movably connected to the top of the outer cylinder 1, and the feed pipe 3 is fixedly connected to the top of the lid 2, facilitating the transportation of gypsum material into the interior of the device. The lid 2 acts as a partition for the internal space. Then, the rotation of the rotating motor 4 at the bottom causes the separation cylinder 6 inside to rotate. The inner wall of the separation cylinder 6 has multiple sets of small holes, which allow the gypsum material to rotate and desulfurize inside. At the same time, a liquid adding device 7 is also installed on the outer wall of the outer cylinder 1. The liquid adding device 7 can assist in adding chemical raw materials to the gypsum during the desulfurization process, accelerating the reaction into crystallization, making the device more convenient to use.
[0027] Example 2
[0028] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, one end of the connecting rod 71 is fixedly connected to the outer wall of the outer cylinder 1, the other end of the connecting rod 71 is fixedly connected to a ring pipe 72, the outer wall of the ring pipe 72 is fixedly connected to an inlet pipe 73, one end of the inlet pipe 73 is fixedly connected to a valve pipe 74, and the inner wall of the ring pipe 72 is fixedly connected to a conveying pipe 75.
[0029] The conveying pipe 75 is bent, and one end of the conveying pipe 75 is inserted into the top of the separation cylinder 6.
[0030] In this embodiment, the combined action of the outer cylinder 1 and the liquid-adding device 7 makes the device more convenient to use. The liquid-adding device 7 is fixedly installed on the outer wall of the outer cylinder 1 via the connecting rod 71, and then the two ends are fixedly connected to the inlet pipe 73, which allows chemical materials to be added to both ends to enter the interior for chemical reaction. At the same time, a valve pipe 74 is provided at the connection port to prevent gas from being discharged from the inside through the inlet pipe 73 to the outer wall of the device and pollute the environment. The shape of the conveying pipe 75 is bent, and the liquid can directly enter the interior of the separation cylinder 6 from the top. Therefore, during the conveying process, the water pressure valve force at the inlet end is relatively large to ensure the normal transport of the liquid, making the device more convenient to use.
[0031] Example 3
[0032] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the support platform 5 includes a support cylinder 51, the top of the support cylinder 51 is fixedly connected to a base 52, the outer wall of the base 52 is provided with a plurality of drainage holes 53, and the bottom of the base 52 is fixedly connected to a plug-in end 54.
[0033] A tube 61 is fixedly connected to the bottom center of the separation cylinder 6, a rotating cylinder 63 is fixedly connected inside the separation cylinder 6, a stirring rod 64 is fixedly connected to the top outer wall of the rotating cylinder 63, and a drain hole 62 is opened at the bottom of the tube 61.
[0034] The output end of the rotating motor 4 passes through the interior of the support cylinder 51, and its top end is movably connected to the bottom of the insert cylinder 61.
[0035] In this embodiment, the combined action of the rotating motor 4, the support platform 5, and the separation cylinder 6 makes the device more convenient to use. The top of the rotating motor 4 passes through the interior of the support platform 5 and is connected to the separation cylinder 6. The output end of the rotating motor 4 is threaded into the interior of the insertion cylinder 61, which rotates in the opposite direction to the motor, preventing the separation cylinder 6 from falling off. The interior of the separation cylinder 6 is connected to the stirring rod 64 through the rotating cylinder 63, causing the separation cylinder 6 to rotate inside while the stirring rod 64 rotates in the same direction, thus promoting faster desulfurization of the gypsum material inside. The separation cylinder 6 is inserted into the interior of the support platform 5, which keeps it stable during rotation. The liquid is discharged from the outer wall of the separation cylinder 6, and the crystals enter the interior of the crystal outlet tube 81 through the drain hole 62 and are discharged outside the device, making the device more convenient to use.
[0036] The working principle of the separation device used for the crystallization of desulfurized gypsum will be explained in detail below.
[0037] like Figure 1-4As shown, when this separation device for desulfurized gypsum crystallization is in use, a lid 2 is movably connected to the top of the outer cylinder 1, and a feed pipe 3 is fixedly connected to the top of the lid 2, facilitating the transport of gypsum material into the device. The lid 2 acts as a partition for the internal space. Then, the rotation of the bottom rotating motor 4 causes the internal separation cylinder 6 to rotate. The inner wall of the separation cylinder 6 has multiple sets of small holes, allowing the gypsum material to rotate and desulfurize inside. At the same time, a liquid adding device 7 is also installed on the outer wall of the outer cylinder 1. The liquid adding device 7 can assist in adding chemical raw materials to the gypsum during the desulfurization process, accelerating the reaction into crystallization, making the device more convenient to use. The liquid adding device 7 is fixedly installed on the outer wall of the outer cylinder 1 through a connecting rod 71, and then the two ends are fixedly connected to the inlet pipe 73, facilitating the addition of chemical materials from both ends to enter the interior for chemical reaction. At the same time, a valve pipe 74 is provided at the connection port to prevent gas from escaping from the inside through the inlet pipe 73 to the outer wall of the device, thus protecting the environment. To prevent contamination, the conveying pipe 75 is bent, allowing the liquid to enter the separation cylinder 6 directly from the top. Therefore, a larger water pressure valve at the inlet is required during the conveying process to ensure normal liquid transport and make the device more convenient to use. The top of the rotating motor 4 passes through the interior of the support platform 5 and connects to the separation cylinder 6. The output end of the rotating motor 4 is threaded into the interior of the insert 61, rotating in the opposite direction to the motor, preventing the separation cylinder 6 from falling off. The interior of the separation cylinder 6 is connected to the stirring rod 64 via the rotating cylinder 63, causing the separation cylinder 6 to rotate internally while the stirring rod 64 rotates in the same direction, thus accelerating the desulfurization of the gypsum material inside. The separation cylinder 6 is inserted into the interior of the support platform 5 to maintain stability during rotation. The liquid is discharged from the outer wall of the separation cylinder 6, and the crystals enter the crystal outlet pipe 81 through the drain hole 62 and are discharged outside the device, making the device more convenient to use.
[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
