Specifically, the first plate slot 13 is disposed in the accommodating space 11 of the first outer casing 11 and partitions the accommodating space 11 into a flow space 117, wherein the liquid input end 151 and the liquid output End 153 and gas output 155 are in fluid communication with flow space 117.

The liquid entering from the liquid input end 151 above the first outer casing 11 is first accumulated in the accommodating groove 135 of the uppermost first plate groove 13. When the accumulated liquid height exceeds the height of the side plate 131, the liquid will be The accommodating groove 135 of the upper first plate groove 13 overflows to the accommodating groove 135 of the lower first plate groove 13, and the liquid finally flows to the bottom of the first outer casing 11.

The heating unit 17 is disposed below the stacked first plate grooves 13, and for example, the heating unit 17 may be disposed at the bottom of the first outer casing 11. The heating unit 17 is configured to increase the temperature of the gas and the liquid inside the first plate groove 13 and the accommodating space 111. For example, the temperature of the liquid in each of the accommodation tanks 135 is increased.

The temperature of the ammonia water 121 in the tank 135 is lower.

The temperature of the ammonia water 121 gradually increases as it approaches the heating unit 17, and the ammonia content of the ammonia water 121 gradually decreases. Specifically, when the ammonia water 121 is transported to the lowest position and is in contact with the heating unit 17, most of the ammonia in the ammonia water 121 is precipitated due to an increase in temperature, and an aqueous solution 123 which meets environmental protection emission standards is produced.

In an embodiment of the present invention, the temperature of the heating unit 17 may be between 50 degrees Celsius and 150 degrees Celsius, and the mass concentration of the ammonia gas 125 discharged from the gas output end 155 is about 25%.

A plurality of second plate grooves 33 are disposed in the second outer casing 31, and a flow space 117 is formed in the second outer casing 31. The second plate slot 33 of the ammonia concentration increasing device 30 includes a plate body 331 and a side plate 333, and a receiving groove 335 is formed through the plate body 331 and the side plate 333. Basically, the structure and arrangement of the second plate groove 33 It is similar to the first plate groove 13 of the ammonia water treatment device 10, and the description thereof will not be repeated here. The cooling unit 37 is disposed above the stacked second plate grooves 33 and serves to lower the temperature of the gas and liquid inside the second plate grooves 33 and the flow space 117.

The second outer casing 31 includes at least one gas input end 351, at least one gas output end 353 and at least one liquid output end 355, wherein the gas input end 351, the gas output end 353 and the liquid output end 355 are all in fluid communication with the second outer casing 31.

Due to the action of the cooling unit 37, the temperature of the second plate groove 33 in the second outer casing 31 may be lower than the temperature of the outside. After the ammonia gas 125 contacts the second plate groove 33, the moisture in the ammonia gas 125 will condense on the lower surface of the second plate groove 33 due to the temperature drop, thereby removing the moisture in the ammonia gas to increase the ammonia gas. The concentration of 125 produces a high concentration of ammonia 321 . In addition, the condensed aqueous solution 323 flows into the accommodating groove 335 of the lower second plate groove 33 due to the action of gravity, so that the aqueous solution 323 in the accommodating groove 335 of the second plate groove 33 gradually increases and overflows to The lower second plate groove 33 and the bottom of the second outer casing 31.

In an embodiment of the present invention, as shown in FIG. 13, the ammonia concentration raising device 30 may be integrated into the ammonia water treatment device 10/40, and the first outer casing 11 of FIG. 1 and the second outer casing of FIG. The body 31 is integrated into an outer casing 41, for example, an ammonia concentration raising device 30 is disposed in a stacked manner within the ammonia water treatment device 10/40. The ammonia water treatment device 40 mainly includes an outer casing 41, a plurality of plate grooves 43, a heating unit 17, and a cooling unit 37.

The structure of the outer casing 41 of the present embodiment is similar to that of the first outer casing 11 and the second outer casing 31, and the configuration of the plate groove 43 is similar to that of the first plate groove 13 and the second plate groove 33, wherein the plate groove 43 includes A plate body 431 and at least one side plate 433 are disposed on the upper surface of the plate body 431, and a receiving groove 435 is formed between the plate body 431 and the side plate 433. In addition, the arrangement and arrangement of the plate grooves 43 in the outer casing 41 are similar to those of FIGS. 1 and 12, and the description thereof will not be repeated here.

In the present embodiment, the heating unit 17 is mainly disposed under the stacked plate grooves 43, and the cooling unit 37 is disposed above the stacked plate grooves 43. The liquid input end 451 is connected to an intermediate position of the outer casing 41. The outer casing 41 above and below the liquid input end 451 is provided with a plate groove 43, for example, a plurality of stacked plate grooves 43. The liquid output end 453 is disposed below the outer casing 41 and/or the liquid input end 451, for example, the liquid output end 453 is located between or below the lowermost plate groove 43 and the heating unit 17. The gas output end 455 is disposed above the outer casing 41 and/or the liquid input end 451, for example, the gas output end 455 is located between or above the uppermost plate groove 43 and the cooling unit 37.

The lower heating unit 17 is for heating the plate groove 43 located below the liquid input end 451, and the upper cooling unit 37 is for cooling the plate groove 43 above the liquid input end 451. For example, the heating unit 17 and the plate groove 43 below the liquid input end 451 can be defined as a heating zone 42, and the cooling unit 37 and the plate groove 43 above the liquid input end 451 can be defined as a condensation zone 44, wherein the function of the heating zone 42 As illustrated in Figure 1, the function of the condensing zone 44 is as described in Figure 12. The ammonia water 121 entering from the liquid input end 451 overflows to the lower plate groove 43 and the heating unit 17, and is heated to generate the aqueous solution 123 and the ammonia gas 125, wherein the aqueous solution 123 flows to the lower side of the outer casing 41, and is discharged from the liquid output end. The 453 flows out of the outer casing 41, and the ammonia gas 125 moves above the outer casing 41.

When the ammonia gas 125 moves over the outer casing 41, it will be cooled by the cooling unit 37, so that the temperature of the ammonia gas 125 is lowered. The water vapor in the ammonia gas 125 is condensed on the lower surface of the plate tank 43, thereby removing the moisture in the ammonia gas to increase the concentration of the ammonia gas 125, and generating a high concentration ammonia gas 321, wherein the high concentration ammonia gas 321 may be output by a gas output 455 above the outer casing 41.

In another embodiment of the present invention, as shown in FIG. 14, the ammonia water treatment device 40 may also include at least one delivery pump 48 and at least one line 49, wherein the liquid output end 453 is connected to the line 49 through the transfer pump 48. The line 49 penetrates the outer casing 41 at a position close to the liquid output end 453 and the liquid input end 451, and forms a circulation line inside the outer casing 41. A portion of the line 49 in the outer casing 41 is located in the receiving groove 435 of the plate groove 43, for example, the line 49 is located in the receiving groove 435 of the plate groove 43 of the heating zone 42, and may extend to a portion of the plate groove 43 in the condensation zone 44. . The line 49 will contact the aqueous solution 123 in the accommodating tank 435, and the aqueous solution in the line 49 assists the heating unit 17 to heat the aqueous solution 123, thereby further improving the heating efficiency and reducing the energy loss.

Generally, the waste ammonia water is usually treated by a bubble column or a shell-and-tube heat exchanger. For example, in the bubble column, each plate of the bubble column is heated after the ammonia water is heated by the bubble column and a part of the ammonia water is vaporized. There will be 3-7% of the droplets that will pass or extend to the previous plate, where the ammonia concentration of the droplets is similar to that of ammonia. When the mist is entrained with water on the upper plate, it will increase the moisture of the upper plate and reduce the ammonia concentration of the upper plate. The shell and tube heat exchanger can avoid the droplets generated during the vaporization of ammonia water compared to the bubble column.

Although the shell-and-tube heat exchanger can reduce the generated droplets, there are still problems such as complicated structure, high production cost, and poor heating efficiency. To this end, the present invention further proposes a configuration of the ammonia water treatment apparatus 10/40 in which the ammonia water is heated by the heating unit 17 and/or the lowermost plate groove 13/43, although mist droplets may be generated. However, since the temperature of the upper plate groove 13/43 is low, when the droplet is transferred to the upper plate groove 13/43, it is absorbed by the ammonia water 121 in the receiving groove 135/435 of the upper plate groove 13/43, and There will be no problem with the droplets passing or extending to the upper layer.

Since the temperature of the ammonia water 121 in the accommodating groove 135/435 of the lower plate groove 13/43 is higher, the temperature of the ammonia gas 125 and the water gas discharged from the lower accommodating groove 135/435 is higher than the upper accommodating groove 135/435. The ammonia water 121 inside is high and can be used to heat the upper plate grooves 13/43, and the heating efficiency can be improved. When the ammonia gas 125 discharged from the tank 135/435 and the water gas heated the upper tank 135/435, the temperature of the ammonia gas 125 and the water vapor will decrease, and a higher proportion of water vapor will condense in the tank. The lower surface of 13/43 can also reduce the droplets and increase the concentration of ammonia 125. For example, when 5% of water vapor is liquefied, the concentration of ammonia can be increased by about 3%. Therefore, the ammonia water treatment device 10/40 of the present invention can effectively reduce the droplets and increase the concentration of the ammonia gas compared to the bubble column, and has a simple structure and is produced compared to the shell-and-tube heat exchanger. Low cost and high heating efficiency.

The above description is only one of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, that is, the changes in shape, structure, features and spirit as described in the scope of the present patent application are Modifications are intended to be included in the scope of the present patent application.
