Description

Technical Field

[0001] This utility model belongs to the field of storage device technology, specifically, it relates to a device and system for collecting leaks of ethylene glycol aqueous solution. Background Technology

[0002] During the operation of indoor ski resorts, the air conditioning system needs to run continuously to maintain an indoor temperature of -3 to -5 degrees Celsius. Since this temperature is below the freezing point of water, ethylene glycol needs to be added to the air conditioning water system as a refrigerant to prevent the water in the refrigeration pipes from freezing. However, ethylene glycol aqueous solutions are slightly toxic, and a leak in the system would have serious consequences for personal safety and the environment.

[0003] In the prior art, such as the hot ethylene glycol box disclosed in patent document CN211282180U (application number: CN201922240540.8), it is mainly for the storage and transportation of hot ethylene glycol. Not only is the cost high, but the application scenario is also different from the leakage collection requirements when cold ethylene glycol is used as a refrigerant in the air conditioning system in this solution, and it cannot effectively solve the technical problems in this field. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a device and system for collecting leaks of ethylene glycol aqueous solution.

[0005] According to the present invention, a leakage collection device for ethylene glycol aqueous solution includes a collection tank body, a water inlet, a solenoid valve, a vent, a level gauge, a signal terminal, a drain outlet, a detection port, a controller, and a collection tank base. The water inlet is provided on the top left side of the collection tank body through a straight pipe, the signal terminal is installed on the top right side of the collection tank body, and the drain outlet is provided on the bottom of the collection tank body through a straight pipe.

[0006] In a preferred embodiment: a collection box base is provided on both the left and right sides of the bottom of the collection box body.

[0007] In a preferred embodiment: a vent is provided at the top center of the collection box body through an arc-shaped pipe.

[0008] In a preferred embodiment: a detection port is provided on the side end of the collection box body through a straight pipe.

[0009] In a preferred embodiment: a level gauge is vertically installed on the connecting pipe of the detection port.

[0010] In a preferred embodiment: both the inlet and outlet pipes are connected to electromagnetic valves via flanges.

[0011] In a preferred embodiment: the solenoid valve and the signal terminal are both electrically connected to the controller.

[0012] This utility model also provides an ethylene glycol aqueous solution leakage collection system, including the aforementioned ethylene glycol aqueous solution leakage collection device, with multiple collection tank bodies arranged separately, and the inlet connected to the corresponding leakage pipe.

[0013] In a preferred embodiment: the solenoid valve at the water inlet of each of the collection tank bodies remains in the normally open state.

[0014] In a preferred embodiment: each of the collection tanks independently achieves liquid level monitoring and pressure balancing.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model achieves automatic collection and alarm control of ethylene glycol aqueous solution leakage through the coordinated design of the collection tank body, solenoid valve, level gauge, and controller. When the liquid level reaches the alarm threshold, the controller automatically closes the inlet solenoid valve and sends a signal to prevent the leaked liquid from continuing to spread. At the same time, manual centralized collection is achieved through the drain outlet, effectively preventing the slightly toxic ethylene glycol aqueous solution from causing harm to people and the environment, and significantly improving the safety of indoor ski resort air conditioning systems.

[0017] 2. The device consists of conventional pipes, valves, and detection elements, assembled using common processes such as welding and flange connections, resulting in a simple structure and convenient installation. Furthermore, the solenoid valves and controller are connected via signal lines, enabling fully automated control of liquid level monitoring and valve opening and closing, reducing manual intervention and maintenance costs, and demonstrating strong engineering practicality and promotional value.

[0022] Example 1

[0023] like Figure 1 As shown, this utility model provides a device for collecting leaked ethylene glycol aqueous solution, including a collection tank body 1, a water inlet 2, an electromagnetic valve 3, a vent 4, a level gauge 5, a signal terminal 6, a drain outlet 7, a detection port 8, a controller 9, and a collection tank foundation 10. The collection tank body 1 has collection tank foundations 10 on both the left and right sides of its bottom. The top left side of the collection tank body 1 has a water inlet 2 connected to it via a straight pipe. The top center of the collection tank body 1 has a vent 4 connected to it via an arc-shaped pipe. The top right side of the collection tank body 1 has a signal terminal 6 installed thereon. The bottom of the collection tank body 1 has a drain outlet 7 connected to it via a straight pipe. Electromagnetic valves 3 are connected to the connecting pipes of the water inlet 2 and the drain outlet 7 via flanges. A detection port 8 is located on the side of the collection tank body 1 via a straight pipe. A level gauge 5 is vertically installed on the connecting pipe of the detection port 8. The electromagnetic valve 3 and the signal terminal 6 are electrically connected to the controller 9. The external controller 9 independently controls the electromagnetic valve 3 based on the level information fed back by the signal terminal 6.

[0024] Working principle

[0025] In this embodiment, when an ethylene glycol aqueous solution leaks in an indoor ski resort, the liquid enters the collection tank body 1 through inlet 2. The liquid level can be observed through level gauge 5, and the solenoid valve 3 of inlet 2 is open at this time. When the liquid in the collection tank body 1 reaches the alarm level, a signal is fed back to controller 9 through signal terminal 6. After receiving the signal, controller 9 controls the inlet solenoid valve 3 to close and issues an audible and visual alarm to remind management personnel to take emergency measures. When hazardous materials collection personnel need to collect the leaked liquid, they can manually operate controller 9 to open the solenoid valve 3 of drain outlet 7 to drain the liquid, collect it, and then transport it. Detection port 8 can be used to detect the concentration of the liquid in the collection tank body 1 during normal operation. Vent 4 is normally open, and an insect screen is installed at the pipe opening to maintain the liquid pressure balance in the collection tank body 1.

[0026] Example 2

[0027] As a preferred example of Embodiment 1, this embodiment provides an ethylene glycol aqueous solution leakage collection system, including the aforementioned ethylene glycol aqueous solution leakage collection device. The collection tank body 1 is distributed in a dispersed manner, and the inlet 2 is connected to the corresponding leakage pipe to collect leakage liquid from different points more efficiently.

[0028] Working principle

[0029] In this embodiment, the ethylene glycol aqueous solution at each leak point is connected to the inlet 2 of the corresponding collection tank body 1 through an independent pipe. The solenoid valve 3 of the inlet 2 is kept open to ensure that the leaked liquid flows into the collection tank body 1 in a timely manner. The collection tank body 1 can independently realize liquid level monitoring and pressure balance. The liquid level in each collection tank body 1 is displayed in real time by the liquid level gauge 5. When the liquid level of a certain collection tank body 1 reaches the alarm threshold, the signal terminal 6 transmits a signal to the corresponding controller 9. After receiving the signal, the controller 9 closes the solenoid valve 3 of the inlet 2 of the collection tank body 1 and issues an audible and visual alarm. The warning is only issued for the leak point and does not affect the operation of other collection systems. When dealing with the leaked liquid in a certain collection tank body 1, the operator can manually control the controller 9 corresponding to the collection tank to open the solenoid valve 3 of the drain outlet 7 to discharge and recover the liquid. Other collection tanks can still work normally.
