The distribution chamber ensures even water distribution, effectively improving ammonia water preparation efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of ammonia preparation technology, and specifically relates to an ammonia preparation device. Background Technology

[0002] An ammonia water generator is a specialized device that continuously and stably produces ammonia water of a specific concentration by dissolving gaseous ammonia in water. It is a modern, automated, safe, and efficient specialized chemical equipment. It completely changes the traditional, outdated method of preparing ammonia water by manually handling and mixing it. It is particularly suitable for industrial scenarios requiring large-scale, continuous, and stable supply of ammonia water of a specific concentration, and is an indispensable unit in modern environmental protection and chemical production.

[0003] During the use of ammonia water generators, industrial water and gaseous ammonia are usually transported into the generator for mixing and absorption. To improve the absorption effect, a packing layer is usually installed inside the ammonia water generator. The packing layer can effectively promote the mixing and absorption of water and ammonia. However, the water inlet pipe in the ammonia water generator is usually installed on one side of the generator. The water source flows into the generator from one side, which makes it impossible for the water source to be effectively dispersed into the packing layer, thus affecting the working efficiency of ammonia water preparation. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an ammonia water generator, comprising: The tank body has a liquid filling pipe connected to its top for filling the tank body with water, and a liquid drain pipe connected to its bottom for discharging ammonia water. A packing layer is installed inside the tank and located below the liquid filling pipe; A blower pipe, installed inside the tank and located below the packing layer, is used to deliver ammonia gas into the tank. A condensation chamber, located at the bottom of the tank, is used to reduce the temperature of the ammonia water. The diversion chamber is fixedly installed on the inner wall of the tank and located between the liquid filling pipe and the packing layer. An overflow ring is provided on the inner wall of the diversion chamber protruding upward.

[0017] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please refer to the following: Figures 1 to 3 The ammonia water generator provided by this utility model will now be described. The ammonia water generator includes a tank 1, a packing layer 2, a gas venting pipe 3, a condensation chamber 4, and a distribution chamber 5. A liquid filling pipe 11 for filling the tank 1 with water is connected to the top of the tank 1, and a drain pipe 12 for discharging ammonia water is provided at the bottom of the tank 1. The packing layer 2 is installed inside the tank 1 and located below the liquid filling pipe 11. The gas venting pipe 3 is installed inside the tank 1 and located below the packing layer 2, for supplying ammonia gas into the tank 1. The condensation chamber 4 is located at the bottom of the tank 1 for reducing the temperature of the ammonia water. The distribution chamber 5 is fixedly installed on the inner wall of the tank 1 and located between the liquid filling pipe 11 and the packing layer 2. An overflow ring 51 protrudes upward from the inner wall of the distribution chamber 5.

[0019] The ammonia water preparer provided in this embodiment, compared with the prior art, is equipped with a tank 1, with a liquid inlet pipe 11 at the top and a liquid outlet pipe 12 at the bottom. The liquid inlet pipe 11 is used to fill the tank 1 with water, and after the ammonia water is prepared, it can be discharged through the liquid outlet pipe 12. Simultaneously, a distribution chamber 5, a packing layer 2, a venting pipe 3, and a condensation chamber 4 are arranged sequentially from top to bottom on the tank 1. In this application, water is added from the top of the tank 1 through the liquid inlet pipe 11, and ammonia gas is added into the tank 1 through the venting pipe 3. Simultaneously, the water is distributed through the distribution chamber 5 and overflows evenly into the packing layer 2 through the overflow ring 51, ensuring uniform water distribution within the packing layer 2 and allowing for sufficient absorption of ammonia gas, thus improving the ammonia water preparation efficiency. Furthermore, the prepared ammonia water is cooled inside the condensation chamber 4, and when the ammonia water concentration reaches the designed concentration, it can be discharged through the liquid outlet pipe 12 at the bottom of the tank 1. By setting up the diversion chamber 5, the water source can be evenly distributed, effectively improving the preparation efficiency of ammonia water.

[0020] In some embodiments, the aforementioned diversion chamber 5 can be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The bottom of the diversion chamber 5 is provided with multiple leakage holes, which are evenly spaced along the circumference of the diversion chamber 5. The liquid filling rate of the liquid filling pipe 11 is greater than the leakage rate of the leakage holes. Therefore, water can still overflow through the overflow ring 51 during the liquid filling process.

[0021] Specifically, in this embodiment, the drainage holes allow excess water inside the distribution chamber 5 to be drained, preventing residual liquid from affecting the subsequent water-ammonia mixing ratio. This also ensures effective drainage of ammonia from the tank 1 later. Furthermore, the evenly spaced drainage holes along the circumference of the distribution chamber 5 allow the liquid inside to be evenly distributed and flow into the packing layer 2, improving the ammonia absorption efficiency.

[0022] In some embodiments, the filler layer 2 may be as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The packing layer 2 includes a conical hopper 21 for supporting the packing, with multiple elongated holes on its sidewall. The conical hopper 21 is fixedly installed on the inner wall of the tank body 1, and its inner diameter gradually decreases from top to bottom. After water overflows from the diversion chamber 5 into the packing layer 2, the conical hopper 21 guides the water flow, increasing the contact area with ammonia. Simultaneously, the shape of the conical hopper 21 guides ammonia towards the outer periphery of the packing layer 2, while the water overflowing from the diversion chamber 5 flows to the outer ring of the packing layer 2, ensuring effective and sufficient contact between the water and ammonia.

[0023] Specifically, in this embodiment, multiple elongated holes are provided on the side wall of the conical material silo 21. The length direction of the elongated holes is arranged along the radial direction of the conical material silo 21, and multiple layers of elongated holes are arranged along the radial direction of the conical material silo 21. The multiple elongated holes are evenly spaced along the circumference of the conical material silo 21. The arrangement of the elongated holes facilitates the flow of water and ammonia.

[0024] In some embodiments, the tapered splitter 6 described above can be employed as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3A conical diverter 6 is installed inside the overflow ring 51. The conical diverter 6 is coaxially arranged with the overflow ring 51, and the outer diameter of the bottom end of the conical diverter 6 is larger than the inner diameter of the overflow ring 51. The conical diverter 6 is located inside the overflow ring 51 and extends downward to the bottom of the overflow ring 51. After overflowing through the overflow ring 51, the water falls to the outside of the conical diverter 6 for secondary diversion. Through the conical diverter 6, the water can be diverted to the outer ring of the conical feed silo 21, and then gradually permeate into the remaining packing part inside the conical feed silo 21. The shape of the conical feed silo 21 and the packing inside the conical feed silo 21 increase the water flow area and improve the contact area between the water and ammonia, thereby improving the absorption effect of the water on ammonia.

[0025] Preferably, in this embodiment, the vertical projection of the overflow ring 51 is located on the conical diverter 6, while the vertical projection of the leakage hole at the bottom of the diversion chamber 5 is located on the outside of the conical diverter 6. The water source can be further distributed through the leakage hole and the diversion of the conical diverter 6.

[0026] Specifically, in this embodiment, the conical distributor 6 has a cylindrical structure, thereby preventing ammonia from remaining inside the conical distributor 6.

[0027] In some embodiments, the air tube 3 described above can be as follows: Figure 2 The structure shown. See also Figure 2 The venting pipe 3 has a ring-shaped structure and multiple vent holes for conveying ammonia gas. An annular support plate is fixedly installed inside the tank body 1 to support the venting pipe 3, and the venting pipe 3 is fixedly mounted on the support plate. The venting pipe 3 is connected to an external ammonia gas delivery pipe. When ammonia gas is delivered into the venting pipe 3, it can be dispersed through the venting pipe 3, allowing the ammonia gas to be discharged through the multiple vent holes.

[0028] In some embodiments, the air tube 3 described above can be as follows: Figure 2 The structure shown. See also Figure 2 Above the venting pipe 3, a conical guide ring 7 is installed to guide the gas towards the axis of the tank 1. The conical guide ring 7 is located above the venting pipe 3. The venting pipe 3 is fixedly installed on the inner wall of the tank 1. After the ammonia gas flows out from the inside of the venting pipe 3, it can increase the ammonia gas's travel distance by passing through the conical guide ring 7, thereby improving the ammonia absorption efficiency.

[0029] Specifically, in this embodiment, the conical guide ring 7 is always located inside the liquid surface to ensure contact between ammonia and water source and improve the absorption efficiency of ammonia.

[0030] In some embodiments, the tapered guide ring 7 described above can be adopted as follows: Figure 2 The structure shown. See also Figure 2The conical guide ring 7 also has multiple vent holes on its sidewall, which are evenly spaced along the circumference of the conical guide ring 7. These vent holes allow ammonia gas to be further dispersed after entering the conical guide ring 7, resulting in multiple small bubbles that integrate into the ammonia solution, thus further improving the ammonia absorption efficiency.

[0031] Specifically, by setting up vents, the travel distance of ammonia gas can be increased, and ammonia gas can be dispersed, thereby improving the mixing effect of ammonia gas and ammonia water.

[0032] In some embodiments, the drain pipe 12 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 A circulation pump 8 is connected to the drain pipe 12. The outlet of the circulation pump 8 is connected to the tank body 1 and is located above the distribution chamber 5. The circulation pump 8 can pump ammonia water back into the top of the tank body 1, allowing the ammonia water that has not reached the required concentration to continue absorbing ammonia gas, eventually bringing the ammonia water to the appropriate concentration. Furthermore, the delivery end of the circulation pump 8 is located at the top of the tank body 1 and above the distribution chamber 5. The distribution chamber 5 can divert the ammonia water, ensuring that it is evenly distributed onto the packing layer 2 after passing through it.

[0033] Preferably, in this embodiment, the outlet end of the circulating pump 8 is arranged opposite to the liquid filling pipe 11 on the tank 1. When adding water to the tank 1, the ammonia water from the liquid filling pipe 11 and the outlet end of the circulating pump 8 can be evenly distributed through the distribution chamber 5.

[0034] Specifically, in this embodiment, a liquid outlet pipe is connected to the circulating pump 8, and the liquid outlet pipe is connected to a liquid outlet end. A discharge pipe is also connected to the middle of the liquid outlet pipe. Control valves for controlling the flow status are installed on both the liquid outlet pipe and the discharge pipe. The discharge pipe is used to discharge the ammonia water inside the tank 1, and the circulation or discharge of the ammonia water can be controlled by the control valve.

[0035] In some embodiments, the condensation chamber 4 described above can be as follows: Figure 2 The structure shown. See also Figure 2 The condensation chamber 4 is equipped with a heat exchanger 41, and the drain pipe 12 on the tank body 1 is located below the heat exchanger 41. The heat exchanger 41 carries a cooling medium, which can reduce the temperature of the ammonia water and improve the stability during the ammonia absorption process.

[0036] Specifically, in this embodiment, the drain pipe 12 is located below the heat exchanger 41. The ammonia water generates heat during the absorption of ammonia gas. After being cooled by the heat exchanger 41, it is pumped into the tank 1 by the circulation pump 8 to reabsorb ammonia gas, thereby increasing the concentration of ammonia water. The absorption effect of ammonia water is improved by lowering the temperature of the ammonia water.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
