Detailed Implementation
[0028] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0029] Reference Figures 1 to 3As shown, a cooling device includes a housing 1, an air inlet pipe 2, an air outlet pipe 3, a liquid inlet pipe 4, a liquid outlet pipe 5, and a connecting pipe 6. The housing 1 has spaced-apart air chambers 101, liquid inlet chambers 102, and liquid outlet chambers 103, with the liquid inlet chambers 102 and 103 respectively located on opposite sides of the air chambers 101. The air inlet pipe 2 is connected to the lower end of the housing 1, and the air outlet pipe 3 is connected to the upper end of the housing 1. Both the air inlet pipe 2 and the air outlet pipe 3 are connected to the air chambers. 101 is connected; wherein, the liquid inlet pipe 4 is connected to the lower end of the housing 1 and is connected to the liquid inlet chamber 102, the liquid outlet pipe 5 is connected to the upper end of the housing 1 and is connected to the liquid outlet chamber 103, the connecting pipe 6 is connected inside the housing 1, and the connecting pipe 6 passes through the air chamber 101 and connects the liquid inlet chamber 102 and the liquid outlet chamber 103. The liquid inlet pipe 4, the liquid inlet chamber 102, the connecting pipe 6, the liquid outlet chamber 103 and the liquid outlet pipe 5 constitute a cooling water flow channel.
[0030] Specifically, in the cooling device of this application, the inlet pipe 4, the inlet chamber 102, the connecting pipe 6, the outlet chamber 103, and the outlet pipe 5 constitute a cooling water flow channel. In practical applications, the cooling water circulates in the cooling water flow channel, while the exhaust gas containing ammonia and hydrogen chloride enters the gas chamber 101 from the inlet pipe 2 and exits from the outlet pipe 3. During this process, the cooling water cools the exhaust gas, and the ammonia and hydrogen chloride are cooled and reacted to form ammonium chloride. The ammonium chloride is relatively stable after recombination and will be adsorbed on the cavity wall of the gas chamber 101. Thus, the content of ammonia and hydrogen chloride in the exhaust gas can be reduced, thereby reducing the cost of subsequent exhaust gas treatment. In addition, the connecting pipe 6, as part of the cooling water flow channel, passes through the gas chamber 101, thus the cooling water flow channel has a good cooling effect on the exhaust gas.
[0031] Since the inlet pipe 4 is located at the lower end of the housing 1 and the outlet pipe 5 is located at the upper end of the housing 1, the cooling water enters from the lower end of the housing 1 and exits from the upper end of the housing 1 when it is transported in the cooling channel. The cooling water has a relatively long transport path, which can further improve the cooling effect on the exhaust gas.
[0032] In this embodiment, the inlet pipe 4 is located on the side of the inlet chamber 102 away from the outlet chamber 103, and the outlet end of the outlet pipe 5 is located on the same side of the housing 1 as the inlet pipe 4. The outlet pipe 5 passes through the inlet chamber 102, the gas chamber 101 and communicates with the outlet chamber 103. Thus, when the cooling water is discharged through the outlet pipe 5, it can also cool the exhaust gas, so that the cooling water can cool the exhaust gas more fully and the cooling channel has a good cooling effect on the exhaust gas. In addition, the outlet end of the outlet pipe 5 and the inlet pipe 4 are located on the same side of the housing 1, which facilitates the pipe layout of the outlet pipe 5 and the inlet pipe 4 when connected to the cooling circulation system.
[0033] In this embodiment, there are multiple connecting pipes 6, which are arranged horizontally at intervals in a group. The connecting pipes 6 are arranged in multiple groups at intervals from top to bottom. Thus, the connecting pipes 6 are evenly distributed in the air cavity 101, which can further improve the cooling effect of the cooling water channel on the exhaust gas.
[0034] In this embodiment, there are multiple boxes 1 connected in sequence. Among two adjacent boxes 1, the exhaust pipe 3 of one box 1 is connected to the inlet pipe 2 of the other box 1 through a connecting pipe 7. Thus, the exhaust gas needs to undergo multiple cooling processes when it is output from the cooling device, which can reduce the content of ammonia and hydrogen chloride in the exhaust gas as much as possible, thereby further reducing the cost of subsequent exhaust gas treatment.
[0035] In practical applications, a humid environment can be created inside the air chamber 101. As a result, ammonium chloride adsorbed on the cavity wall of the air chamber 101 will slide down to the bottom wall of the air chamber 101 in the humid environment. Based on this, in this embodiment, the air chamber 101 includes a main chamber 1011 and a discharge chamber 1012 arranged and connected from top to bottom. The liquid inlet chamber 102 and the liquid outlet chamber 103 are respectively arranged on opposite sides of the main chamber 1011. The air inlet pipe 2 and the air outlet pipe 3 are both connected to the main chamber 1011. The discharge chamber 1012 is a conical chamber with a space that gradually decreases from top to bottom. The cooling device also includes a discharge pipe 8, which is connected to the bottom of the box body 1 and is connected to the discharge chamber 1012. Specifically, the conical discharge chamber 1012 plays a guiding role, which is conducive to ammonium chloride sliding down into the discharge pipe 8, making it easier to collect the ammonium chloride.
[0036] Furthermore, the cooling device also includes a gate valve 9, which is connected to the discharge pipe 8. The function of the gate valve 9 is to allow ammonium chloride to remain in the tank 1. When a certain amount of ammonium chloride is stored in the tank 1, a collection container is placed below the discharge pipe 8, and the ammonium chloride is discharged from the tank 1 by opening the gate valve 9. The structure is simple, the ammonium chloride collection operation is convenient, and the gate valve 9 can also prevent exhaust gas leakage.
[0037] Furthermore, the cooling device also includes an installation platform 10 and a support 11. The bottom end of the support 11 is connected to the ground, and the installation platform 10 is connected to the top end of the support 11. A discharge space 100 is formed between the installation platform 10 and the support 11. The box 1 is connected to the top surface of the installation platform 10, and the lower part of the box 1 extends through the installation platform 10 into the discharge space 100. The discharge pipe 8 is located in the discharge space 100. Based on this, when collecting ammonium chloride, the collection container is placed in the discharge space 100 to receive the material, which is convenient for operation.
[0038] Furthermore, the housing 1 is provided with a maintenance handhole 12, which is connected to the main chamber 1011. Workers can use the maintenance handhole 12 to inspect the air chamber 101 to ensure the proper functioning of the cooling device. The cooling device also includes a fence 13 and a ladder 14. The fence 13 is connected to the top of the support 11 and surrounds the installation platform 10, located above it. The fence 13 forms an entrance / exit 200. The ladder 14 is connected to the support 11 and is at least partially located below the entrance / exit 200. Specifically, when workers inspect the housing 1, they enter the installation platform 10 from the entrance / exit 200 via the ladder 14. The ladder 14 ensures that workers can perform maintenance smoothly, while the fence 13 ensures the personal safety of workers during maintenance.
[0039] Furthermore, the cooling device also includes a guardrail 15, which is connected to the ladder 14 and surrounds the side of the ladder 14 away from the support 11, forming a passageway between the guardrail 15 and the ladder 14. In the horizontal direction, the guardrail 15 is at least partially opposite the entrance 200. The guardrail 15 on the ladder 14 makes it safer for workers to enter the installation platform 10 through the entrance 200 via the ladder 14.
[0040] Furthermore, the installation platform 10 is made of fiberglass grating, which is strong and lightweight, can bear the weight of the box 1 well, and has good anti-slip performance, which can further ensure the personal safety of the staff.
