Detailed Description
The preferred embodiments of the present invention will now be described with reference to the accompanying drawings.
Embodiments of the present invention will be further explained by the following description in conjunction with the related drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts. In the drawings, the shape and thickness may be exaggerated for simplicity and convenience. It is to be understood that elements not specifically shown in the drawings or described in the specification are of a form well known to those skilled in the art. Many variations and modifications may be made by one of ordinary skill in the art in light of the teachings of the present invention.
Referring to fig. 1 and 2, an ammonia water treatment device 100 of the present embodiment mainly includes a housing 110, a plurality of liquid trays 120, a plurality of communicating pipes 130, a first heater 140, a bypass pipe 150, a water mist generator 160, a pump 170, and a second heater 180.
The housing 110 has a liquid input port 111, a liquid output port 112, and a gas output port 113.
As shown in FIG. 2, a plurality of liquid pans 120 are disposed in the housing 110, and the liquid pans 120 are spaced apart from each other by a specific distance. Here, the outer edge of each liquid pan 120 is integrally connected to the inner wall of the housing 110. Thus, a substantially closed gas flow space 114 is formed between each two adjacent liquid pans 120, between the uppermost liquid pan 120 and the inner wall of the housing 110, and between the lowermost liquid pan 120 and the inner wall of the housing 110. In addition, in the present embodiment, the liquid input port 111 and the gas output port 113 of the casing 110 are located above the plurality of liquid pans 120, and the liquid output port 112 of the casing 110 is located below the plurality of liquid pans 120.
The plurality of communication pipes 130 are connected to and penetrate the plurality of liquid pans 120, respectively (i.e., each communication pipe 130 is connected to and penetrates each liquid pan 120). In the present embodiment, the plurality of communication pipes 130 are spaced from each other in a staggered manner. As described above, the liquid input port 111 and the gas output port 113 of the housing 110 may be communicated with the liquid output port 112 of the housing 110 through the plurality of communication pipes 130 arranged in a staggered manner. In other words, all the gas flowing spaces 114 in the casing 110 are communicated with each other through the plurality of communication pipes 130 arranged in a staggered manner. In addition, as shown in fig. 2 and 3, each of the communication tubes 130 has at least one drainage port 131. Here, when each of the communication tubes 130 is connected to and penetrates each of the trays 120, the drainage port 131 of each of the communication tubes 130 is located above each of the trays 120 corresponding thereto. In other words, the level of the drainage port 131 of each communication tube 130 is greater than the level of each liquid pan 120 corresponding thereto, or the drainage port 131 of each communication tube 130 protrudes above each liquid pan 120 corresponding thereto. In addition, the vents 131 of the present embodiment have a generally V-shaped profile. It should be noted that although the present embodiment is described with each communication tube 130 having one drainage port 131 and the drainage port 131 having a substantially V-shaped profile, the disclosure is not limited thereto. In other words, in other embodiments, each communication tube 130 may have a plurality of drainage ports 131, and the plurality of drainage ports 131 may have the same or different configuration profiles from each other.
As shown in fig. 2, the first heater 140 is disposed in the casing 110, and the first heater 140 is disposed under the liquid trays 120 (i.e., the first heater 140 is disposed in the lowest gas flowing space 114 in the casing 110). In the present embodiment, the first heater 140 is provided to increase the temperature in each gas flow space 114 in the housing 110.
As shown in fig. 1 and 2, the bypass pipe 150 is connected to the housing 110. In more detail, the bypass pipe 150 has an inlet 151 and an outlet 152. In the case where the bypass pipe 150 is connected to the housing 110, the inlet 151 and the outlet 152 are communicated with the housing 110, and the inlet 151 and the outlet 152 are located below the plurality of liquid pans 120, and the outlet 152 is located above the inlet 151. More specifically, the inlet 151 and the outlet 152 of the bypass pipe 150 are communicated with the lowermost gas flow space 114 in the case 110 (or, the inlet 151 and the outlet 152 of the bypass pipe 150 are communicated with the gas flow space 114 in which the first heater 140 is disposed).
The water mist generator 160 is connected to the bypass pipe 150. Here, the water mist generator 160 mainly converts the liquid flowing in the bypass pipe 150 into water mist.
The pump 170 is connected to the bypass pipe 150. More specifically, the inlet 151 of the bypass pipe 150 is connected to the outlet 152 of the bypass pipe 150 via the pump 170 and the mist generator 160 in sequence. In this embodiment, the pump 170 is used to drive the liquid in the bypass pipe 150.
The second heater 180 is disposed on the bypass pipe 150. Here, the second heater 180 is provided to assist in increasing the temperature of the liquid flowing in the bypass pipe 150.
Next, an operation of the ammonia water treatment apparatus 100 of the present embodiment for volatilizing ammonia gas from ammonia water will be described.
First, since the boiling point of ammonia is about 37.7 ℃, the first heater 140 can be operated to maintain the temperature in the housing 110 above 37.7 ℃.
Next, as shown in fig. 2, ammonia water a to be treated is input into the housing 110 through the liquid input port 111. At this time, the ammonia a flows from top to bottom through each of the liquid trays 120 to the bottom of the housing 110 (i.e., the lowest gas flow space 114 in the housing 110). More specifically, the ammonia a on each of the liquid trays 120 overflows to the next liquid tray 120 through the corresponding communication pipe 130, and finally overflows to the bottom of the housing 110. It should be noted that, because the communication pipe 130 has the drainage port 131 with the V-shaped profile, the ammonia water a will overflow downwards regularly through the drainage port 131 with the V-shaped profile, and a multi-directional overflow waterfall phenomenon will not be formed in the communication pipe 130, so that the subsequent upward flow of ammonia gas and water mist will not be affected. Meanwhile, since the temperature in the housing 110 is maintained above 37.7 ℃ by the operation of the first heater 140, ammonia gas and a part of moisture are volatilized (or evaporated) from the ammonia water a, and the volatilized ammonia gas and a part of moisture flow upward sequentially through each communicating tube 130 to the top of the housing 110 (i.e., the uppermost gas flow space 114 in the housing 110) and then flow out through the gas outlet 113 to be collected. At the same time, the aqueous solution containing no ammonia or the aqueous ammonia A still containing part of the ammonia continues to overflow downwards.
As described above, since the first heater 140 is disposed at the bottom of the housing 110 (i.e., the lowest gas flow space 114 in the housing 110), the temperature distribution in the housing 110 varies with the distance between the liquid pan 120 or the gas flow space 114 and the first heater 140. That is, the temperature of the lower tray 120 or gas flow space 114 will be higher, while the temperature of the upper tray 120 or gas flow space 114 will be lower. Therefore, even if the ammonia a volatilizes in a small amount from the upper tray 120, the ammonia continues to be further volatilized from the ammonia a due to the temperature rise as the ammonia a continues to overflow downward. When the ammonia water a finally overflows to the bottom of the housing 110 (i.e., the lowest gas flow space 114 in the housing 110), there is hardly any ammonia therein, and it is converted into an aqueous solution meeting the emission standards of environmental regulations. Finally, the aqueous solution is discharged to the outside through the liquid outlet 112 of the housing 110.
On the other hand, in order to further improve the speed and efficiency of the ammonia gas volatilization from the ammonia a, the pump 170 may draw the aqueous solution from the bottom of the housing 110 (i.e., the lowermost gas flow space 114 within the housing 110) through the inlet 151 into the bypass pipe 150, and then the aqueous solution entering into the bypass pipe 150 may be further heated by the second heater 180. The further heated aqueous solution then flows through the mist generator 160 and is converted into a mist of high temperature by the mist generator 160. The high-temperature water mist is ejected through the outlet 152 of the bypass pipe 150, and is diffused and ascended in the housing 110 through the communication pipes 130 in sequence. Here, when the high-temperature mist contacts the bottom surface of each liquid pan 120, the heat of the mist is transferred to the ammonia a on each liquid pan 120 through the heat exchange effect, so as to further volatilize the ammonia from the ammonia a (i.e., to more rapidly volatilize the ammonia from the ammonia a). Meanwhile, the mist contacting the bottom surface of each liquid pan 120 condenses into an aqueous solution due to the release of heat, flows onto each liquid pan 120, and then flows to the bottom of the housing 110 through each communicating tube 130 along with the ammonia a or other aqueous solution. Then, the aqueous solution at the bottom of the housing 110 is repeatedly heated by the first heater 140, pumped by the pump 170 and converted into high-temperature water mist by the water mist generator 160, or discharged to the outside through the liquid outlet 112 of the housing 110.
In addition, although the ammonia water treatment apparatus 100 of the present embodiment is operated with a plurality of liquid trays 120 and a plurality of communication pipes 130, it may be operated with only one liquid tray 120 and one communication pipe 130, or it may be operated with two liquid trays 120 and two communication pipes 130, and the rest of the components and the structure are maintained the same.
In summary, the ammonia water treatment device disclosed in the present invention can volatilize ammonia gas in the ammonia water more rapidly, so as to greatly improve the efficiency of ammonia water treatment, thereby being beneficial to industrial application.
The above description is only for the purpose of illustrating preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, which is defined by the claims and the description of the invention.
