[0041] Please refer to Figures 1 to 5 The utility model provides a kind of ammonia preparation device, including liquid ammonia raw material tank 1, evaporator 2, oil-gas separator 3, mixed absorber 4, cooler 5 and finished product storage tank 6 etc.

[0042] The liquid ammonia raw material tank 1 is used to store liquid ammonia, and it is connected with the evaporator 2, so that the liquid ammonia can be evaporated into gaseous ammonia by the evaporator 2 after being pressed out from the liquid ammonia raw material tank 1. The evaporator 2 has two heat exchange units isolated from each other, and the liquid ammonia in one of the heat exchange units can be evaporated into gaseous ammonia by injecting hot water into the other heat exchange unit. The oil-gas separator 3 is connected with the evaporator 2, and is used to separate oil and solid impurities from the gaseous ammonia, so as to reduce the oil and impurities in the ammonia water produced. The mixed absorber 4 is connected with the oil-gas separator 3, and the mixed absorber 4 is connected with a pure water supply device, so that the pure water can be sent into the mixed absorber 4 to absorb the gaseous ammonia, and thus semi-product ammonia water can be obtained. The cooler 5 is connected with the mixed absorber 4, and is used to cool the semi-product ammonia water. The finished product storage tank 6 is connected with the cooler 5, and is used to store the finished product ammonia water.

[0043] Further, the oil-gas separator 3 includes a tank body 31, a mesh rack 32, a filler 33, a water spraying pipe 34, a connecting seat 35 and a mounting plate 36.

[0044] The filler 33 is arranged between the two filler 33 rack 32. The water spraying pipe 34 extends into the tank body 31, and the water spraying pipe 34 is located above the filler 33 rack 32 and the filler 33, so that the filler 33 can be cleaned by spraying water downward through the water spraying pipe 34. The connecting seat 35 can be fixed on the tank wall of the tank body 31 by welding, but is not limited to welding; the mounting plate 36 is fixedly sleeved on the water spraying pipe 34, and the mounting plate 36 is detachably connected with the connecting seat 35. When the filler 33 does not need to be cleaned, the mounting plate 36 can be separated from the connecting seat 35, so that the water spraying pipe 34 can be removed from the tank body 31. When the oil-gas separator 3 works, the oil and impurities carried in the gaseous ammonia gas cannot enter the water spraying pipe 34, so that the water spraying pipe 34 does not have the problem of blockage. When the filler 33 needs to be cleaned, the water spraying pipe 34 is extended into the tank body 31, and the mounting plate 36 is connected with the connecting seat 35 to fix and install the water spraying pipe 34.

[0045] It can be seen that the water spraying pipe 34 is arranged above the filler 33 rack 32 and the filler 33, so that the filler 33 can be periodically cleaned without removing the top cover of the oil-gas separator 3, and the filler 33 cleaning operation is simple. By detachably connecting the mounting plate 36 on the water spraying pipe 34 with the connecting seat 35 of the tank body 31, when the filler 33 does not need to be cleaned, the mounting plate 36 is separated from the connecting seat 35, so that the water spraying pipe 34 can be removed from the tank body 31. When the oil-gas separator 3 works, the oil and impurities carried in the gaseous ammonia gas cannot enter the water spraying pipe 34, so that the water spraying pipe 34 does not have the problem of blockage.

[0046] Specifically, the mounting plate 36 and the connecting seat 35 can be connected by a screw rod. The gas inlet of the oil-gas separator 3 can be arranged on the lower side wall of the tank body 31, and the gas outlet of the oil-gas separator 3 can be arranged on the top of the tank body 31.

[0047] As shown in Figure 4 Optionally, the ammonia water preparation device further comprises a sealing plate 16, which is detachably arranged on the connecting seat 35.

[0048] As shown in Figure 2 and Figure 5As shown, optionally, the water spraying pipe 34 comprises a water spraying pipe body 341 and a plurality of spray heads 342 distributed on the water spraying pipe body 341. The plurality of spray heads 342 can increase the water spraying range of the water spraying pipe 34, so that the filler 33 can be effectively cleaned. The connecting seat 35 is provided with a through hole 351 for the water spraying pipe body 341 and the spray head 342 to pass through at the same time, so as to ensure that the water spraying pipe body 341 and the spray head 342 can enter the inside of the tank body 31 at the same time.

[0049] As shown, Figure 2 As shown, optionally, the water spraying pipe 34 is connected with a water conveying pipe 7. The water conveying pipe 7 is connected with a water conveying pump 8, and the water conveying pipe 7 can be a water conveying hose, so as to facilitate the disassembly and assembly of the water spraying pipe 34 on the tank body 31. The water conveying pump 8 is connected with a water source through a pipeline, so as to ensure that there is sufficient cleaning water.

[0050] As shown, Figure 2 As shown, optionally, the tank body 31 is provided with a flow guide plate 9 in the shape of an umbrella; the flow guide plate 9 is located above the water spraying pipe 34, and the top of the flow guide plate 9 is provided with an opening 91. The flow guide plate 9 can improve the flow direction of the gas, so that the gaseous ammonia gas can contact the flow guide plate 9 before passing through the opening 91 upward, and the oil and impurities carried in the gaseous ammonia gas are blocked by the flow guide plate 9, so as to be able to drop downward on the filler 33, and then fall into the bottom of the tank body 31. Compared with using only the filler 33 to separate the oil and impurities in the gaseous ammonia gas, the separation effect is better when the flow guide plate 9 and the filler 33 are used in cooperation, so as to be able to reduce the number of oil and gas separators 3.

[0051] As shown, Figure 2 As shown, optionally, the number of the flow guide plates 9 is not less than two. The plurality of flow guide plates 9 can further improve the efficiency of oil and gas separation.

[0052] As shown, Figure 2 As shown, optionally, the lower part of the flow guide plate 9 is provided with a liquid outlet hole 92, so that the oil adsorbed on the upper surface of the flow guide plate 9 can be discharged downward on the filler 33 through the liquid outlet hole 92.

[0053] Of course, in order to realize the cleaning of the flow guide plate 9, a detachable water spraying pipe 34 can also be arranged above the uppermost flow guide plate 9.

[0054] As shown, Figure 2 As shown, optionally, the ammonia water preparation device further comprises a liquid discharge pipe 11, a filter 12 arranged on the liquid discharge pipe 11, and a pump body 13 located downstream of the filter 12 and connected with the liquid discharge pipe 11. The pump body 13 can be connected with an oil collector through a pipeline, so as to be used for recycling the oil separated by the oil and gas separation, and at the same time, the oil at the bottom of the tank body 31 can be discharged from the tank body 31 in time. The filter 12 is used for filtering the impurities in the oil, so that the impurities are not easily introduced into the pump body 13, and the service life of the pump body 13 can be prolonged.

[0055] As Figure 2 shown, optionally, the drain pipe 11 is provided with a bypass drain pipe 14; the filter 12 comprises a first filter 121 and a second filter 122, the first filter 121 and the second filter 122 are respectively arranged on the drain pipe 11 and the bypass drain pipe 14, the drain pipe 11 and the bypass drain pipe 14 are both provided with a valve 15, and the valve 15 is respectively located upstream of the first filter 121 and the second filter 122. By arranging the bypass drain pipe 14 and arranging the second filter 122 on the bypass drain pipe 14, when the first filter 121 is damaged, the impurities in the oil can still be filtered through the second filter 122. The valve body is used to control whether the oil passes through the first filter 121 or the second filter 122 when the pump body 13 is working.

[0056] As ​ shown, optionally, the lower part of the tank body 31 is provided with a liquid level meter 10. The liquid level meter 10 can be a flap type liquid level meter 10, which can be used to measure the liquid level in the tank body 31, so as to facilitate the production personnel to judge whether the pump body 13 needs to be opened to drain the oil in the tank body 31 to the outside of the tank body 31.
