AI Technical Summary
The existing denitrification station does not completely absorb ammonia, resulting in escape. Furthermore, the lack of timely manual water replacement leads to secondary escape, which fails to meet environmental protection requirements.
Design a water seal device to prevent ammonia escape. Use a level gauge and an ammonia concentration meter to monitor the liquid level and ammonia concentration in the water tank. Use a stainless steel float valve to control the inlet of tap water and the outlet of ammonia water to achieve automatic water circulation and gas recirculation.
It effectively prevents ammonia escape, meets environmental protection requirements, and realizes an automated water circulation process, improving ammonia absorption efficiency and safety.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of environmental protection device technology, specifically relating to a water seal device to prevent ammonia gas from escaping. Background Technology
[0002] At present, the denitrification station generally directly introduces the ammonia gas to be treated into the water storage tank or water storage vessel, and after being absorbed by the water, it is discharged into the atmosphere. The problems are: (1) the ammonia gas is not completely absorbed, and there is ammonia gas escape, which does not meet the environmental protection requirements; (2) when the ammonia gas concentration in the water is saturated, it is necessary to manually change the water, but manual water change is not timely and inconvenient, which will also lead to secondary escape of ammonia gas. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this utility model is to provide a water seal device to prevent ammonia escape, thereby solving the problem of ammonia escape from ammonia storage tanks, meeting environmental protection requirements, and enabling water circulation.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a water seal device for preventing ammonia escape, comprising a water tank body, a level gauge and an ammonia concentration meter installed inside the water tank body, an ammonia inlet pipe installed on one side wall of the water tank body, an exhaust pipe installed at the upper end of the ammonia inlet pipe, one end of the exhaust pipe being connected to the ammonia inlet pipe, and the other end being connected to the water tank body through a one-way exhaust valve, an ammonia drain valve also being installed on the side wall of the water tank body below the ammonia inlet pipe; a tap water inlet valve is installed on the other side wall of the water tank body, and the tap water inlet valve is connected to an external tap water pipe.
[0005] A further improvement is that the tap water inlet valve is also connected to a stainless steel float valve.
[0006] A further improvement is that both the level gauge and the ammonia concentration gauge are inserted into the water tank, with an insertion depth exceeding 3 / 4 of the water tank's height.
[0007] A further improvement is that the water tank body is a sealed body.
[0008] This invention employs a level gauge and an ammonia concentration gauge installed inside a sealed water tank. When ammonia gas is introduced into the tank through the ammonia gas inlet pipe, tap water is injected through the tap water inlet valve. When the tap water level reaches the maximum height set by the level gauge, the water supply stops under the action of the stainless steel float valve. At this time, ammonia gas is continuously introduced into the tap water. When the ammonia concentration measured by the ammonia concentration gauge reaches the set value (at this point, it is assumed that the tap water can no longer absorb ammonia gas), the ammonia water drain valve discharges the ammonia water, and at the same time, the tap water inlet valve starts to supply water under the action of the stainless steel float valve, thus achieving circulating water supply. If there is excess gas, it is discharged into the ammonia gas inlet pipe through the exhaust pipe connected to the ammonia gas inlet pipe and then circulated back in. Attached Figure Description

[0011] The present invention will now be described in further detail with reference to the accompanying drawings:
[0012] like Figure 1 As shown, a water seal device for preventing ammonia escape includes a water tank 1. A level gauge 2 and an ammonia concentration meter 3 are installed inside the water tank 1. An ammonia inlet pipe 9 is installed on one side wall of the water tank 1. An exhaust pipe 4 is installed at the upper end of the ammonia inlet pipe 9. One end of the exhaust pipe 4 is connected to the ammonia inlet pipe 9, and the other end is connected to the water tank 1 via a one-way exhaust valve 5. An ammonia drain valve 7 is also installed on the side wall of the water tank below the ammonia inlet pipe 9. A tap water inlet valve 6 is installed on the other side wall of the water tank 1. The tap water inlet valve 6 is connected to an external tap water pipe and is also connected to a stainless steel float valve 8. All pipe connections to the water tank are sealed connections. The water tank body 1 is a sealed body. In order to better detect the liquid level and ammonia concentration in the water tank, the liquid level gauge 2 and the ammonia concentration gauge 3 are both inserted into the water tank body 1, with an insertion depth exceeding 3 / 4 of the height of the water tank.
[0013] When this invention is in use, ammonia gas is introduced into the water tank through the ammonia gas inlet pipe, and tap water is injected through the tap water inlet valve. When the tap water level reaches the maximum height set by the level gauge, the water supply stops under the action of the stainless steel float valve. At this time, ammonia gas is continuously introduced into the tap water. When the ammonia concentration measured by the ammonia concentration meter reaches the set value (at this point, it is assumed that the tap water can no longer absorb ammonia gas), the ammonia water drain valve is opened to discharge the ammonia water. At the same time, the tap water inlet valve starts to supply water under the action of the stainless steel float valve, realizing the circulation of water supply. If there is excess gas, it is discharged into the ammonia gas inlet pipe through the exhaust pipe connected to the ammonia gas inlet pipe and then circulated back in, effectively preventing the escape of ammonia gas, meeting environmental protection requirements, and realizing water circulation.
