Design Parameters of Explosion-Propylene Oxide Storage Ventilation System?
Design Parameters of Explosion-proof Ventilation System to Propylene Oxide Storage Warehouse
propylene oxide is an crucial chemical raw material, which is broadly applied in polyurethane, epoxy resin, textile auxiliaries and other fields. Propylene oxide is flammable and explosive, and improper regulation during storage is able to easily lead to security accidents. From what I've seen, Therefore, in the design of propylene oxide storage warehouse, explosion-proof ventilation system is a vital part. This paper will examine the key elements of the explosion-proof ventilation system of the propylene oxide storage warehouse in detail from the perspective of design parameters. But
1. For example Explosion-Proof Ventilation System Design Objectives
Propylene oxide will form an explosive mixture atmospheric if it leaks or volatilizes during storage. When the explosion limit is reached, the ignition source such as open flame or electrostatic spark might result in an explosion accident. Therefore, the core goal of the explosion-proof ventilation system is to minimize the levels of propylene oxide vapor in the warehouse below the reduced explosion limit through efficiently ventilation. Crazy, isn't it?. The ventilation system also needs to take into account multiple security standards such as explosion-proof, fire prevention and corrosion prevention. In my experience,
2. ventilation design parameters
ventilation number method
The calculation of ventilation volume is an crucial basis to the design of explosion-proof ventilation system. Generally, the atmosphere change rate method is a common method to calculating the ventilation volume. According to the Code to Fire Protection Design of Buildings and the Code to security of Hazardous Chemicals Warehouse, the ventilation rate of the propylene oxide storage warehouse shall not be less than 3 times per hour, and might be increased to greater than 5 times per hour under special circumstances. The higher the ventilation rate, the better the ventilation effect, however the energy consumption also increases accordingly. Therefore, it's necessary to find a stability between security and economy in the design. leakage calculation method
Another method of calculating ventilation is based on the leakage of propylene oxide. Assuming that the leakage of propylene oxide in the warehouse is Q (unit: kg/h), the ventilation rate should be at least 10 times of Q to ensure that the leaked propylene oxide vapor is able to be discharged in time. to instance, if the leakage of propylene oxide is 0. And Based on my observations, 5 kg/h, the ventilation rate should be at least 5 m³/s. But
3. wind speed design parameters
In the propylene oxide storage warehouse, the design of wind speed should take into account the uniformity and security. Too low wind speed will lead to the accumulation of propylene oxide vapor in the dead corner area, while too high wind speed might result in equipment vibration or dust flying, affecting safe production. In my experience, Generally speaking, the wind speed of propylene oxide storage warehouse should be controlled between 0. You know what I mean?. Furthermore 5 and
1. But 0 m/s. The distribution of wind speed should be uniform to prevent too low or too high wind speed in regional areas.
4. atmosphere outlet design parameters
The location and design of the atmosphere outlet immediately affect the efficiency of the ventilation system. The exhaust outlet of the propylene oxide storage warehouse shall be set at the top of the warehouse, and the propylene oxide vapor shall be efficiently discharged by using the principle of hot gaseous rising. I've found that The opening area of the atmosphere outlet shall meet the ventilation standards, and the ratio of the area of the atmosphere outlet to the area of the warehouse shall not be less than 1:
50. In my experience, Specifically The atmosphere outlet should be far away from the atmosphere inlet to prevent short circuit of hot and cold atmosphere and affect the ventilation effect.
5. But For instance explosion-proof ventilation system other design parameters
gaseous detection equipment
Propylene oxide seepage detector and combustible gaseous detector shall be installed in the propylene oxide storage warehouse. These devices is able to monitor the gaseous levels in the warehouse in real time. From what I've seen, When the levels reaches the set value, the system will automatically start the exhaust fan or issue an alarm signal. The selection of gaseous detection equipment shall meet the explosion-proof standards to ensure safe operation in explosive environments. In fact Type Selection of Explosion-proof Fan
The core equipment of the explosion-proof ventilation system is the explosion-proof fan. In my experience, When selecting a fan, it's necessary to consider factors such as atmosphere volume, atmosphere pressure, and power. But The explosion-proof fan of the propylene oxide storage warehouse shall have a high explosion-proof grade, such as Ex d IIA T4 protection grade, and meet the standards of relevant standards. The installation position of the fan should be far away from the fire source to prevent security accidents caused by equipment failure. In particular security manage parameters
In order to ensure the security of the explosion-proof ventilation system, it's necessary to set the security interlock device in the system. Based on my observations, Generally speaking to instance, when the levels of propylene oxide in the warehouse reaches a certain value, the system will automatically close the ventilation pipe to prevent the propylene oxide vapor atmospheric from flowing back to other areas. And The atmosphere outlet shall be equipped with flame arrester and explosion-proof valve to prevent external fire from entering the warehouse through the atmosphere outlet. I've found that
6. operation and maintenance
The explosion-proof ventilation system of the propylene oxide storage warehouse needs regular inspection and maintenance. But I've found that Including cleaning the dust in the ventilation pipe, checking the operation status of the fan, calibrating the gaseous detection equipment, etc. Through regular maintenance, to ensure that the system is always in the best working condition, to provide a reliable security to the storage of propylene oxide. But According to research summary
The design of an explosion-proof ventilation system to a propylene oxide storage warehouse is a complex and elaborate process that involves a thorough consideration of multiple design parameters. And Through the reasonable design of key parameters such as ventilation, wind speed, exhaust outlet, and the selection of gaseous detection equipment and explosion-proof fan, the explosion risk of propylene oxide vapor is able to be efficiently reduced to ensure the security of the storage process. In the future, with the continuous research of the chemical sector, explosion-proof ventilation methodology will continue to innovate to provide greater efficient and safe solutions to the storage of hazardous chemicals such as propylene oxide.
