Technical Field

[0001] This utility model belongs to the field of melamine tail gas cooling, drying and dehydration technology, specifically a melamine tail gas cooling, drying and dehydration device. Background Technology

[0002] Melamine, commonly known as melamine, is a triazine-based nitrogen-containing heterocyclic organic compound. It appears as white monoclinic crystals, is sparingly soluble in water, ethylene glycol, glycerol, and pyridine, and slightly soluble in ethanol. Melamine forms salts with acids and condenses with formaldehyde to form various hydroxymethyl melamines. Under slightly acidic conditions, it can condense with hydroxymethyl derivatives to form resins.

[0003] Existing melamine tail gas cooling, drying and dehydration devices generally achieve cooling and drying by passing the tail gas into a condenser. However, in actual production, due to the relatively fixed structure of traditional devices, condensate and cooling water are prone to stagnation inside the device, which is quite inconvenient.

[0032] like Figures 1 to 5As shown in the figure, a melamine tail gas cooling, drying and dehydration device according to an embodiment of the present invention includes a condenser cylinder 1. A first U-shaped tube 11, a second U-shaped tube 12, and a third U-shaped tube 13 are fixedly connected to the inner wall of the condenser cylinder 1, and the multiple first U-shaped tubes 11, second U-shaped tubes 12, and third U-shaped tubes 13 are arranged correspondingly. An inlet cylinder 14 and an outlet cylinder 15 are fixedly connected to the side wall of the condenser cylinder 1, and the inlet cylinder 14 and outlet cylinder 15 are arranged correspondingly. A spherical distributor 18 is fixedly connected to the side wall of the inlet cylinder 14. A water injection hole 16 is fixedly connected to the top of the condenser cylinder 1. A drain hole 17 is fixedly connected to the bottom of the condenser cylinder 1, and the water injection hole 16 and drain hole 17 are arranged correspondingly. During operation, cold water can enter the interior of the condenser cylinder 1 through the water injection hole 16 and be discharged through the drain hole 17. Simultaneously, melamine tail gas can enter the first U-shaped tube 11, the second U-shaped tube 12, and the third U-shaped tube 13 through the inlet cylinder 14. The melamine exhaust gas is introduced into the first U-tube 12 and the third U-tube 13, and finally discharged through the exhaust cylinder 15.

The spherical distributor 18 fixed to the side wall of the intake cylinder 14 can make the exhaust gas enter the first U-tube 11, the second U-tube 12 and the third U-tube 13 more evenly. Through the above structure, the first U-tube 11, the second U-tube 12 and the third U-tube 13 are set so that the melamine exhaust gas is affected by the cold water inside the three tubes, which is conducive to improving the cooling and condensation efficiency of the exhaust gas. The spherical distributor 18 improves the flow distribution of the exhaust gas, which is conducive to achieving uniform flow of melamine exhaust gas.

[0033] like Figures 1 to 3As shown, a fixing block 2 is fixedly connected to the bottom of the condenser cylinder 1, and a turntable 21 is rotatably connected to the bottom of the fixing block 2; a base plate 22 is fixedly connected to the bottom of the turntable 21; a first limiting block 23 is fixedly connected to the top of the base plate 22, and a second limiting block 24 is fixedly connected to the bottom of the condenser cylinder 1, with the second limiting block 24 corresponding to the first limiting block 23; a hydraulic actuator 25 is rotatably connected between the condenser cylinder 1 and the base plate 22, with the two hydraulic actuators 25 corresponding to each other; during operation, the base plate 22 is located at the top of the ground and remains parallel to the ground, while the condenser cylinder 1 located at the top of the base plate 22 is tilted, that is, the end of the condenser cylinder 1 closest to the air inlet cylinder 14 and the air outlet cylinder 15 tilts towards the ground. At this time, the first U-shaped tube 11 and the second U-shaped tube 1... Condensate in the third U-shaped tube 13 can flow out under gravity. At the same time, since the fixed block 2 and the turntable 21 are rotatably connected, the operator can adjust the angle of the condenser cylinder 1 by driving the hydraulic device 25, so as to more conveniently drain all the cold water inside the condenser cylinder 1. The first limiting block 23 and the second limiting block 24 serve to limit the condenser cylinder 1. Through the above structure, the first limiting block 23 and the second limiting block 24 limit the condenser cylinder 1, thereby controlling the tilt angle of the condenser cylinder 1. The fixed block 2, the turntable 21 and the hydraulic device 25 realize the adjustable angle of the condenser cylinder 1, which provides convenience for the operator to drain the cold water and helps to avoid cold water remaining inside the condenser cylinder 1.

[0034] like Figures 1 to 4 As shown, a condenser valve 3 is threadedly connected to the side wall of the air inlet cylinder 14 and the air outlet cylinder 15, and a motor 31 is fixedly connected to the bottom of the condenser valve 3; a valve core 32 is fixedly connected to the output end of the motor 31, and the valve core 32 is rotatably connected inside the condenser valve 3; during operation, condensate flows out from the first U-tube 11, the second U-tube 12 and the third U-tube 13 and reaches the inside of the air inlet cylinder 14 and the air outlet cylinder 15. The operator can control the rotation of the valve core 32 by driving the motor 31, thereby controlling the opening and closing state of the condenser valve 3; through the above structure, the motor 31 controls the opening and closing state of the condenser valve 3, which improves the automation level of the device, facilitates the operator's condensate drainage action, and helps to prevent melamine tail gas from leaking through the condensate drainage channel.

[0035] like Figure 2 , Figure 3 and Figure 5As shown, a support plate 4 is provided on the inner wall of the condenser cylinder 1; a fixing groove 41 is provided on the side wall of the support plate 4, and multiple fixing grooves 41 are arranged correspondingly; a water passage groove 42 is provided on the side wall of the support plate 4, and multiple water passage grooves 42 are arranged correspondingly; during operation, the multiple fixing grooves 41 on the side wall of the support plate 4 are set to correspond to the dimensions of the first U-shaped tube 11, the second U-shaped tube 12 and the third U-shaped tube 13, and the three tubes pass through the corresponding fixing grooves 41 and are limited by the support plate 4. The cold water entering the condenser cylinder 1 through the water injection hole 16 can circulate inside the condenser cylinder 1 through the water passage groove 42; through the above structure, the support plate 4 limits the first U-shaped tube 11, the second U-shaped tube 12 and the third U-shaped tube 13, which helps to improve their stability, prevents them from falling off or deforming under the action of gravity, and helps to improve the service life of the device.

[0036] like Figures 1 to 3 As shown, a flange 5 is provided at the end of the condenser cylinder 1, and bolts 51 are provided between the condenser cylinder 1 and the flange 5; multiple bolts 51 are arranged in a circumferential array; during operation, the operator can disconnect the flange 5 from the condenser cylinder 1 by removing multiple bolts 51, thereby making it easier to clean the inside of the condenser cylinder 1; through the above structure, the flange 5 and bolts 51 are provided so that the end of the condenser cylinder 1 can be opened, reducing the difficulty of cleaning the inside of the condenser cylinder 1 and improving the cleaning efficiency of the device.

[0037] like Figure 3 As shown, a retaining ring 6 is fixed to the side wall of the flange 5, and the retaining ring 6 is set according to the size of the condenser cylinder 1. During operation, the retaining ring 6 fixed to the side wall of the flange 5 contacts the inner side wall of the condenser cylinder 1. At the same time, whenever the condenser cylinder 1 tilts under the action of the hydraulic device 25, the retaining ring 6 can push the residual cold water to the drain hole 17 by itself. Through the above structure, the retaining ring 6 increases the contact area between the flange 5 and the condenser cylinder 1, which helps to avoid liquid leakage and also helps to drain the residual cold water inside the condenser cylinder 1.

[0038] like Figure 5 As shown, U-shaped blocks 7 are provided on the side wall of the support plate 4, and multiple U-shaped blocks 7 are arranged in a circumferential array. During operation, the U-shaped blocks 7 provided on the side wall of the support plate 4 can increase the contact area between the condenser cylinder 1 and the support plate 4. At the same time, since multiple U-shaped blocks 7 are provided on the side wall of the support plate 4, cold water will pass through the support plate 4 more easily. Through the above structure, the U-shaped blocks 7 increase the contact area between the support plate 4 and the condenser cylinder 1, which helps to improve the stability of the support plate 4, prevents the support plate 4 from tilting, and reduces the difficulty of cold water passing through the support plate 4.

[0039] like Figure 2 and Figure 3As shown, reinforcing plates 8 are fixedly connected to the inner sidewalls of the first limiting block 23 and the second limiting block 24, and multiple reinforcing plates 8 are arranged in a corresponding manner. During operation, the reinforcing plates 8 fixed inside the first limiting block 23 and the second limiting block 24 can enhance their structural strength by themselves. Through the above structure, the reinforcing plates 8 enhance the structural strength of the first limiting block 23 and the second limiting block 24, which is beneficial to extending the service life of the device and reducing the maintenance requirements of the components.

[0040] like Figure 1 As shown, flexible hoses 9 are provided on the side walls of the air inlet cylinder 14 and the air outlet cylinder 15. During operation, the operator can connect the air inlet cylinder 14 and the air outlet cylinder 15 to the corresponding pipes through the flexible hoses 9. Whenever the position of the condenser cylinder 1 changes under the action of the hydraulic device 25, the flexible hose 9 can deform to a certain extent to maintain the stability of the connection between the pipes. Through the above structure, the flexible hose 9 is set to connect the corresponding pipes, thereby avoiding the connection between the pipes from breaking after the position of the condenser cylinder 1 changes, which helps to improve the practicality of the device.

[0041] like Figure 5 As shown, the first U-tube 11, the second U-tube 12, and the third U-tube 13 are made of stainless steel. During operation, the stainless steel materials of the first U-tube 11, the second U-tube 12, and the third U-tube 13 can take advantage of the high structural strength and strong stability of stainless steel. Through the above, the use of stainless steel for the first U-tube 11, the second U-tube 12, and the third U-tube 13 enhances their structural strength and corrosion resistance, which is beneficial to extending the service life of the device.

[0042] During operation, cold water enters the condenser cylinder 1 through the water inlet 16 and exits through the drain hole 17. Simultaneously, melamine exhaust gas enters the first U-shaped pipe 11, the second U-shaped pipe 12, and the third U-shaped pipe 13 through the inlet cylinder 14, and finally exits through the outlet cylinder 15. Workers can guide the melamine exhaust gas into the inlet cylinder 14, allowing it to be cooled and dried by the cold water inside the condenser cylinder 1 as it passes through the first U-shaped pipe 11, the second U-shaped pipe 12, and the third U-shaped pipe 13. The spherical distributor 18, fixed to the side wall of the inlet cylinder 14, ensures that the exhaust gas enters the first U-shaped pipe 11, the second U-shaped pipe 12, and the third U-shaped pipe 13 more evenly. The base plate 22 is located at the top of the ground and... The condenser cylinder 1, positioned parallel to the ground and located on top of the base plate 22, is tilted, with the end of the condenser cylinder 1 closest to the air inlet cylinder 14 and the air outlet cylinder 15 tilting towards the ground. In this position, the condensate in the first U-shaped tube 11, the second U-shaped tube 12, and the third U-shaped tube 13 can flow out under gravity. Simultaneously, because the fixed block 2 and the turntable 21 are rotatably connected, the operator can adjust the angle of the condenser cylinder 1 by driving the hydraulic actuator 25, thus facilitating the complete drainage of the cold water inside the condenser cylinder 1. The first limiting block 23 and the second limiting block 24 limit the condenser cylinder 1. After flowing out from the first U-shaped tube 11, the second U-shaped tube 12, and the third U-shaped tube 13, the condensate will reach the air inlet cylinder 14 and the air outlet cylinder. Inside the condenser 15, the operator can control the rotation of the valve core 32 by driving the motor 31, thereby controlling the opening and closing state of the condenser valve 3. Multiple fixing grooves 41 on the side wall of the support plate 4 are set to correspond to the dimensions of the first U-tube 11, the second U-tube 12, and the third U-tube 13. The three tubes pass through their respective fixing grooves 41 and are limited by the support plate 4. Cold water entering the condenser 1 through the water inlet 16 can circulate inside the condenser 1 via the water channel 42. The operator can disconnect the flange 5 from the condenser 1 by removing multiple bolts 51, thus facilitating cleaning of the interior of the condenser 1. The fixing ring 6 fixed to the side wall of the flange 5 contacts the condenser 1. On the inner wall, whenever the condenser cylinder 1 tilts under the action of the hydraulic device 25, the fixing ring 6 can push the residual cold water towards the drain hole 17. The U-shaped block 7 set on the side wall of the support plate 4 can increase the contact area between the condenser cylinder 1 and the support plate 4. At the same time, since multiple U-shaped blocks 7 are set on the side wall of the support plate 4, the cold water will pass through the support plate 4 more easily. The reinforcing plate 8 fixed inside the first limiting block 23 and the second limiting block 24 can enhance its structural strength. The operator can connect the air inlet cylinder 14 and the air outlet cylinder 15 to the corresponding pipes through the hose 9. Whenever the condenser cylinder 1 changes position under the action of the hydraulic device 25, the hose 9 can deform to a certain extent to maintain the stability of the connection between the pipes.The use of stainless steel in the first U-shaped tube 11, the second U-shaped tube 12, and the third U-shaped tube 13 leverages the high structural strength and stability of stainless steel.
