Design Parameters of Explosion-proof Ventilation System for Butyl Acrylate Storage Tank?

Design parameters of explosion-proof ventilation system for n-butyl acrylate storage tank

in the chemical industry, n-butyl acrylate is a common hazardous chemical. Because of its flammability and volatility, the safety issues during storage have attracted much attention. This article will discuss in detail the design parameters of the explosion-proof ventilation system of the n-butyl acrylate storage tank to ensure the safety of the storage environment.

Hazard characteristics of n-butyl acrylate Butyl acrylate (Butyl Acrylate) is a colorless liquid commonly used in the manufacture of polymers and coatings. Its hazardous characteristics mainly include flammability and volatility. According to research, the flash point of n-butyl acrylate is about -7°C, and the explosion limit is in the range of about 0.5 to 9.5% in air. These characteristics make it a risk of explosion in the tank, so it is important to design an explosion-proof ventilation system.

Relationship between tank structure and ventilation design The structure of the tank directly affects the efficiency of the ventilation system. Common tank types include fixed roof tanks and floating roof tanks. Fixed roof tanks are usually used for large-capacity storage, while floating roof tanks are suitable for reducing evaporation losses due to their better sealing. When designing an explosion-proof ventilation system, the type and capacity of the tank need to be considered to determine the amount and mode of ventilation.

Core parameters of explosion-proof ventilation system

1. Ventilation: Ventilation is one of the key parameters, which should be calculated according to the evaporation rate and gas concentration of n-butyl acrylate in the tank. Generally, the calculation formula takes into account the volumetric flow rate of the gas and the volume of the space inside the tank. Reasonable ventilation can effectively reduce the concentration of combustible gas in the tank and prevent the risk of explosion.

2. Ventilation: natural ventilation and mechanical ventilation are two common ways of ventilation. Natural ventilation relies on wind direction and speed and is suitable for environments with mild explosion risks, while mechanical ventilation is used for high-risk environments with forced exhaust by fans. The design needs to be combined with environmental conditions and storage scale to choose the appropriate way.

3. Explosion-proof equipment: It is necessary to install explosion-proof fans and explosion-proof sensors. The explosion-proof fan can ensure safe operation in an explosive environment, while the sensor is used to monitor the gas concentration in the tank in real time and issue an alarm in time.

Safety Standards and Specifications Compliance with national and industry safety standards is the basis for the design of explosion-proof ventilation systems. For example, China's GB 30871 standard specifies the design requirements for storage tanks for hazardous chemicals. GB 50058 standard specifies the partition and ventilation design requirements for explosive gas environments. Ensuring that the design meets these standards can effectively reduce safety hazards.

Optimal Design and Energy Saving Under the premise of ensuring safety, the optimization design can improve the energy efficiency of the system. Through the intelligent control system, the ventilation volume can be adjusted according to the real-time monitoring data to avoid energy waste. The choice of efficient fans and reasonable ventilation layout can also reduce operating costs.

Epilogue The design of explosion-proof ventilation system of n-butyl acrylate storage tank involves many considerations, from dangerous characteristics to safety standards, each link needs to be carefully designed. Reasonable design of explosion-proof ventilation system can not only prevent explosion accidents, but also improve the overall safety of storage tanks. Through the analysis of this paper, it is hoped that it can provide valuable reference for the relevant designers to ensure the safe operation of the storage tank.
