Is it necessary to install a vent valve and a safety valve on the top of the hydrogen peroxide storage tank? Can the exhaust outlet be directly opened to the atmosphere?

A breathing valve, a safety valve, and an exhaust port need to be installed on top of the hydrogen peroxide storage tank. A breathing valve allows gas to enter and exit the tank freely, while maintaining stable pressure inside the tank. A safety valve can automatically open to release pressure when the pressure inside the tank exceeds the specified safe level, thereby preventing the tank from rupturing or exploding. The exhaust port is also designed to allow the gas inside the tank to be discharged quickly when necessary, in order to prevent dangerous situations from occurring. The exhaust outlet cannot be left directly exposed to the atmosphere, as hydrogen peroxide reacts violently when it comes into contact with other substances, which may lead to dangerous chemical reactions or fire accidents. Therefore, the exhaust outlet needs to be designed as a specialized safety device to ensure the safe discharge of gases from the tank. .

What kind of safety device should be installed on the exhaust outlet?

Exhaust vents generally need to be designed with safety valves or rupture disks as safety devices. Among them: 1. The safety valve is one of the main protective devices that maintains the stable operation of the system within the specified pressure range. When the pressure inside the container exceeds a preset value, the safety valve opens automatically to release the excess pressure gas into the outside atmosphere. 2. Shrapnel, also known as blast membranes or unloading plates, are metal sheets that can break under pressure. Their advantages include high material strength, low cost, light weight, long service life, adjustability, and ease of maintenance. It is also a common safety device in storage tank and pipeline systems today. When external pressure exceeds the designed internal pressure of the container, the rupture disc will break to enable safe release. In summary, regardless of the type of venting safety equipment used, it must be capable of safely and effectively releasing the excess pressure gas from the storage tank, thereby preventing accidents caused by excessive pressure inside the tank. .

Atmospheric pressure equipment does not require safety valves, but it needs pressure relief manholes and breather valves, with the diameter to be calculated accordingly.

Emergency relief valves and breather valves equipped with flame arrestors are mandatory. In addition, safety facilities such as spray cooling, emergency fire suppression, and discharge systems must also be installed
