Due to the particularity of hydrogen, it is necessary to be careful when selecting the installation location of the hydrogen leak alarm to ensure that it can accurately and effectively detect hydrogen leaks and issue alarms in time. Here are some suggested installation locations:
First，Close to potential leak sources
1. Hydrogen storage area
Near the hydrogen tank: Install the tank in a well-ventilated place, and not too far away from the tank, so that the hydrogen can be quickly detected in the case of a leak. It can generally be installed within 1 to 5 meters from the storage tank.
Hydrogen pipeline connections: joints, valves and other parts of the pipeline are prone to leakage, and an alarm can be installed near these locations to find the problem in time. The installation height can be determined based on the actual pipe height, usually 0.5 to 2 meters from the connection point.
2. Use hydrogen around the equipment
Such as hydrogen fuel cell, hydrogen burner and other equipment. Depending on the size and shape of the device, it can be installed within 0.5 to 3 meters from the device and should be installed on the upwind side of the device so that hydrogen leakage can be detected in the first place.
Second, well-ventilated location
1. Interior space
Close to the vents: Install the alarm near the vents such as Windows and ventilation fans, so as to ensure that the leaking hydrogen can quickly spread and be detected. At the same time, avoid installing in dead corners of air flow or places blocked by obstacles.
The top of the room: Because hydrogen is lighter than air and will rise after leakage, consider installing an alarm on the top of the room. However, pay attention to the installation firmly to prevent falling due to vibration and other reasons.
2. Outdoor Spaces
High and unobstructed: When installing outdoors, a high and unobstructed position should be selected to better detect the diffusion of hydrogen in the air. For example, it can be installed on the roof of a building, telephone poles and other locations, but pay attention to waterproof, lightning protection and other protective measures.
Third, personnel can easily detect the position
1. Control room or duty room
The alarm signal of the alarm is introduced into the control room or duty room, so that the operator can know the hydrogen leakage situation in time and take corresponding measures. At the same time, sound and light alarms can be installed in the control room or duty room to enhance the warning effect.
2. Areas where people are often active
Such as workshop passage, office entrance and other places, so that personnel can easily detect the alarm signal of the alarm in daily activities. However, be careful to avoid installation in a location that is too noisy or easily disturbed, so as not to affect the alarm effect.
In short, when installing a hydrogen leak alarm, factors such as the characteristics of hydrogen, potential leak sources, ventilation and personnel awareness should be considered comprehensively, and the appropriate installation location should be selected to ensure that it can effectively play its role and ensure the safety of personnel and equipment.
