Technical Field

[0001] The utility model belongs to the technical field of absorption tanks, and in particular relates to an absorption tank for preventing ammonia from escaping from an ammonia water storage tank. Background Art

[0002] During the storage and use of ammonia water, the escape of ammonia has always been a focus of the industry. Due to the strong volatility and corrosiveness of ammonia water, ammonia gas is easily released during storage and use, which not only leads to the waste of ammonia water resources, but also may cause serious harm to the surrounding environment and human health. Therefore, it is necessary to use an absorption tank to absorb the ammonia gas discharged from the ammonia storage tank, but the traditional absorption tank has certain defects when used.

[0003] For example, in the publication number "CN 212283467 U" discloses an ammonia absorption device located on the top of an ammonia water storage tank, the device comprises an ammonia water storage tank, a base is fixedly installed on the bottom surface of the ammonia water storage tank, an ammonia absorption tank is arranged above one side of the ammonia water storage tank, the bottom surface of the ammonia absorption tank is fixedly connected to the ammonia water storage tank through an I-shaped bracket, a water inlet pipe is fixedly installed on one side of the top surface of the ammonia absorption tank, the ammonia absorption tank is communicated with the inside of the water inlet pipe, an exhaust pipe is fixedly installed on the other side of the top surface of the ammonia absorption tank, the lower end of the exhaust pipe is located below the inside of the ammonia absorption tank and communicates with the inside of the ammonia absorption tank, the upper end of the exhaust pipe is communicated with the ammonia water storage tank through a pipeline, a breathing valve is fixedly installed on the lower end of the pipeline, a first valve is fixedly installed on the lower end of the water inlet pipe, the lower end of the ammonia absorption tank is communicated with the top surface of the ammonia water storage tank through a recovery pipe, and a second valve is fixedly installed on the lower end of the recovery pipe. Although the device can absorb ammonia discharged from the ammonia storage tank when in use, when the device absorbs ammonia through a water body, when the temperature near the device rises, more ammonia will also escape, and the absorption rate is limited.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 As shown, the utility model provides the following technical solutions:

[0024] An absorption tank for preventing ammonia from escaping from an ammonia water storage tank comprises an ammonia storage tank 1 for storing ammonia water, an exhaust pipe 2 is fixedly connected to the top of the ammonia storage tank 1, and an absorber is fixedly connected to the free end of the exhaust pipe 2;

[0025] A first valve 3 is installed on the exhaust pipe 2, the absorber is located above the ammonia storage tank 1, and a cavity for storing water is formed inside the absorber, and a semiconductor refrigeration plate 14 is arranged inside the cavity.

[0026] Through the above technical scheme, ammonia water is stored in the ammonia storage tank 1, and water is stored in the cavity inside the absorber. As the storage time increases, ammonia gas will gradually escape from the ammonia storage tank 1. In order to avoid accidents, when the internal atmospheric pressure of the ammonia storage tank 1 reaches the safety pressure limit, the first valve 3 is opened, and the ammonia gas is transported to the cavity inside the absorber through the exhaust pipe 2, and the semiconductor refrigeration plate 14 is operated to cool the inside of the cavity, thereby increasing the solubility of ammonia gas in water, and the ammonia gas is dissolved in the water inside the cavity to form ammonia water.

[0027] In addition, in the present invention, in order to improve the refrigeration efficiency of the semiconductor refrigeration plate 14, as Figure 4 As shown, a plurality of heat-conducting rings 13 are arranged on one side of the semiconductor refrigeration plate 14 .

[0028] In this embodiment, when the semiconductor refrigeration plate 14 is cooling, the heat conductive ring 13 cooperates to make the semiconductor refrigeration plate 14 reduce the temperature inside the cavity more quickly during cooling, thereby further improving the dissolution efficiency of ammonia.

[0029] Specifically, in one embodiment, regarding the above-mentioned absorbent:

[0030] like Figure 1-Figure 4 As shown, the absorber includes a recovery tank 12, a water adding portion for adding water is provided on the top of the recovery tank 12, and an inner cavity 15 is formed inside the recovery tank 12, and a semiconductor refrigeration plate 14 is installed inside the inner cavity 15;

[0031] The free end of the exhaust pipe 2 is fixedly connected to the top of the recovery tank 12 .

[0032] In this embodiment, water is stored in the inner cavity 15 inside the recovery tank 12. As the storage time increases, ammonia gas will gradually escape when storing ammonia water in the ammonia storage tank 1. In order to avoid accidents, when the atmospheric pressure inside the ammonia storage tank 1 reaches the safety pressure limit, the first valve 3 is opened, and the ammonia gas is transported to the inner cavity 15 through the exhaust pipe 2. The semiconductor refrigeration plate 14 is operated to cool the interior of the inner cavity 15, thereby increasing the solubility of ammonia gas in water. The ammonia gas dissolves in the water inside the inner cavity 15 to form ammonia water, thereby reusing the ammonia gas.

[0033] In addition, in the present invention, after the recovery tank 12 absorbs the ammonia gas escaping from the ammonia storage tank 1, the ammonia gas will mix with the water inside the recovery tank 12 to form ammonia water. In order to recycle the ammonia water, Figure 1-Figure 3 As shown, a return pipe 11 is fixedly connected between the bottom of the recovery tank 12 and the ammonia storage tank 1 , and a third valve 10 is installed on the return pipe 11 .

[0034] In this embodiment, after the ammonia gas is mixed with water in the recovery tank 12 to reform ammonia water, the third valve 10 is opened to discharge the ammonia water into the ammonia storage tank 1 through the return pipe 11, thereby reusing the ammonia gas.

[0035] Furthermore, in the present utility model, regarding the water adding part:

[0036] like Figure 1-Figure 4 As shown, the water adding part includes a water adding pipe 7, the water outlet end of the water adding pipe 7 is fixedly connected to the top of the recovery tank 12, and a second valve 8 is installed on the water adding pipe 7, and an observation window 9 is provided on one side of the recovery tank 12.

[0037] In this embodiment, when personnel need to add water to the recovery tank 12, the second valve 8 is opened, and the water is transported to the recovery tank 12 through the water adding pipe 7. After the water is added, the second valve 8 is closed to complete the addition of water.

[0038] In addition, in the present invention, in order to improve the solubility of ammonia dissolved in the water inside the inner cavity 15, as Figure 1-Figure 4 As shown, a pressure pump 5 is fixedly connected to the top of the recovery tank 12 , and the air inlet and air outlet ends of the pressure pump 5 are fixedly connected to the first air pipe 4 and the second air pipe 6 respectively, and the air outlet end of the second air pipe 6 extends to the interior of the inner cavity 15 .

[0039] In this embodiment, when ammonia is mixed with water in the inner cavity 15 inside the recovery tank 12, the pressure pump 5 works to absorb external gas through the first gas pipe 4 and transport the gas to the inner cavity 15 through the second gas pipe 6, thereby pressurizing the inner cavity 15 and further increasing the solubility of ammonia in the water.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
