Can the design pressure of a wet-type acetylene gas tank be above 4 KPa?
Thread Content
According to the low-pressure steel standards, the pressure in a wet-type acetylene gas tank should not exceed 4 KPa. However, due to the actual requirements of the process, it is necessary to design the tank such that the pressure can reach 8 KPa. Experts, please provide guidance on this.
To increase the pressure in a gas holder, one method is to increase the weight of its bell cover, and the other is to add counterweights. Just calculate it based on the area of the gas tank
If gas pressure is required to reach 8 kPa, the gas in the low-pressure gas tank can be pressurized once using a booster pump to bring it to the required pressure of 8 kPa. .
It’s very simple: calculate the pressure exerted on the top of the gas tank using 8 kPa, subtract the weight of the tank itself, and that gives the weight of the counterweight needed; simply add the appropriate counterweight. But wouldn’t controlling the generator pressure at 8 kPa in the gas tank result in a very high pressure? Why think this way?
No, it’s dangerous; it’s restricted by the water seal height, so it needs to be redesigned.
