Description

Technical Field

[0001] The utility model relates to the field of desalination, in particular to a desalination tank and a desalination system. Background Art

[0002] In the prior art, impurity salts may be formed during the synthesis of compounds, and impurity salts are easy to clog mechanical equipment, affecting production safety and efficiency. For example, morpholine is made of diethylene glycol and liquid ammonia as raw materials. Under a hydrogen environment, it is catalytically reacted to generate the intermediate product diglycolamine, and then a molecule of water is removed and cyclized to generate the product morpholine. Due to the high activity of diethylene glycol, it is easy to crack into carbon dioxide at the reaction temperature, and water is generated in the reaction system. Therefore, in the morpholine production system, carbon dioxide and ammonia generate a large amount of ammonium carbonate salts in water. The generated ammonium salts often clog pipelines, equipment, and pumps, which not only affects the stable operation of the device, but also causes certain safety risks. Whether the traditional production device has a desalination device, the blockage problem is solved by regularly cleaning the pipelines, equipment, and pumps. In the actual production process, the problem of ammonium salt blockage is not completely solved. By stopping the vehicle to clean the blocked parts, there is not only a certain risk but also affects the production efficiency. Therefore, it is necessary to design a desalination device that can remove the impurity salts formed during the compound production process. Utility Model Content

[0028] Example

[0029] Please refer to Figure 1 , see Figure 1 The present embodiment provides a desalination tank 100. The desalination tank 100 provided by the present utility model embodiment can be used for desalination in the morpholine production process, and can also be used for desalination of other chemical raw materials or chemical products. Specifically, the desalination tank 100 includes a tank body 110. The tank body 110 used in the present utility model is a conventional vertical tank in the prior art, but it can be understood that other specifications of the tank body 110 can also be used.

[0030] An air inlet 120 is provided on the side wall of the upper portion of the tank body 110, and the air inlet 120 is provided in a tangential air intake manner. The utility model adopts tangential air intake, which can increase the centrifugal force of the gas, can effectively separate the generated carbonate particles, and is beneficial to the separation and deposition of solid particles.

[0031] A water inlet 130 for introducing clean water is provided on the side wall of the lower part of the tank body 110, and a drain outlet 140 for draining clean water is provided at the bottom of the tank body 110. When the desalination tank 100 needs to be cleaned, water is introduced into the tank body 110 through the water inlet 130 to dissolve the salt in the tank body 110, and then the salt-containing water is drained out of the tank body 110 through the drain outlet 140, thereby cleaning the residual salt in the tank body 110.

[0032] Furthermore, it also includes a central tube 150 , which is disposed in the tank body 110 and connected to the tank body 110 at the center of the tank body 110 . The desalinated gas is transported to the outside of the tank body 110 through the central tube 150 .

[0033] Furthermore, combined with Figure 1 and Figure 2 The desalination tank 100 further includes a first baffle assembly 160. The undesalted gas introduced into the tank body 110 acts on the first baffle assembly 160, which then causes baffles, thereby increasing the gas residence time and the centrifugal force of the gas, thereby effectively separating carbonate particles. At the same time, after the gas enters the tank body 110, it impacts the first baffle assembly 160, and the salt mixed in the gas is deposited on the first baffle assembly 160, thereby achieving the effect of removing salt from the gas.

[0034] Specifically, the first deflector assembly 160 includes a plurality of first deflector members 161 , and the plurality of first deflector members 161 are disposed around the outer periphery of the central tube 150 and connected to the outer periphery of the central tube 150 .

[0035] In the present invention, the number of the first deflectors 161 is 4 and they are evenly distributed around the periphery of the central tube 150 . However, it is understandable that the number of the first deflectors 161 can be appropriately increased or decreased according to actual production requirements.

[0036] Further, the desalination tank 100 further includes a second baffle assembly 170, which is arranged around the inner circumference of the tank body 110 and connected to the tank body 110. Specifically, the second baffle assembly 170 includes a plurality of second baffle members 171, which are respectively arranged around the inner circumference of the tank body 110 and connected to the tank body 110.

[0037] In the present invention, the number of the second deflectors 171 is 4 and they are evenly distributed on the inner circumference of the tank body 110 . However, it is understandable that the number of the second deflectors 171 can be appropriately increased or decreased according to actual production requirements.

[0038] The first deflector 161 and the second deflector 171 have the same structure and can both be plate-shaped structures. The first deflector 161 and the second deflector 171 can both be made of metal or other materials.

[0039] The utility model is provided with 8 baffles to increase the residence time of the gas. At the same time, the speed of the gas is reduced when contacting the baffle plate, and the gas is directly separated at the baffle plate, which is beneficial to the separation of the gas-solid two phases.

[0040] Furthermore, the desalination tank 100 also includes a wire mesh partition 180, which is arranged in the tank body 110 and connected to the tank body 110, and the wire mesh partition 180 is arranged between the first deflection assembly 160 and the gas inlet of the central tube 150. Then, the gas passing through the first deflection member 161 or the second deflection member 171 acts on the wire mesh partition 180 again, which can realize secondary removal of carbonate particles in the gas and improve the desalination efficiency.

[0041] The use process of the desalination tank 100 is as follows: the gas enters the tank body 110 along the tangential direction, and then the gas acts on the first deflector 161 and / or the second deflector 171 to cause deflection, while increasing the centrifugal force of the gas. The gas continues to flow and acts on the wire mesh partition 180 to further remove carbonates in the gas, and then flows out of the tank body 110 through the central tube 150.

[0042] In a second aspect, the utility model provides a desalination system 200, see Figure 3 , which includes a feeding device 210 and the above-mentioned desalination tank 100, and the feeding device 210 is connected to the desalination tank 100. In the present invention, the number of desalination tanks is 2, but the number of desalination tanks can be increased or decreased according to production needs.

[0043] Specifically, the feeding device 210 also includes a liquid ammonia feed pipe 211, a hydrogen feed pipe 212 and a feed main pipe 213. The liquid ammonia feed pipe 211 and the hydrogen feed pipe 212 are respectively connected to the feed main pipe 213, and the other end of the feed main pipe 213 is connected to the desalination tank 100. A valve 220 is provided on the feed main pipe 213.

[0044] Furthermore, the desalination system 200 further includes a cleaning device 230, which is connected to the desalination tank 100; specifically, the cleaning device 230 further includes an inlet pipe 231 and an outlet pipe 232, wherein the inlet pipe 231 is connected to the water inlet 130 of the desalination tank 100, and the outlet pipe 232 is connected to the drain outlet 140 of the desalination tank 100, and valves 220 are provided on the inlet pipe 231 and the outlet pipe 232. When the desalination tank 100 needs to be cleaned, water is passed into the tank body 110 through the inlet pipe 231, and then the water containing dissolved salt is discharged through the outlet pipe 232. By setting up a cleaning system, the risk of misoperation caused by manual cleaning is reduced.

[0045] Furthermore, the valves 220 can be controlled by a program and the desalters can be automatically switched by pressure difference detection, thereby reducing the risk of manual cleaning and improving the level of automation.

[0046] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
