Description

Explosion-proof type spark arrester that bombs

Technical Field

The utility model relates to a spark arrester field especially relates to an explosion-proof type spark arrester that bombs.

Background

Flame arrestors are safety devices used to prevent the spread of flames of flammable gases and flammable liquid vapors. The device for preventing the passage of a propagating flame (deflagration or detonation), which is generally installed in a conduit for transporting combustible gases, or in a ventilated tank, consists of a flame-retardant core, a flame-retardant casing and accessories. One of the requirements for combustion is to reach a certain temperature, i.e. the ignition point. Below the ignition point, combustion is stopped. According to this principle, the spread of the flame can be prevented as long as the temperature of the burning substance is lowered below its ignition point. The flame will become several tiny flames as it passes through the many tiny passages of the flame retardant element. When the flame retardant element is designed inside the flame arrester, the contact area between the fine flame and the channel wall is enlarged as much as possible, the heat transfer is enhanced, and the temperature of the flame is reduced below the ignition point, thereby preventing the flame from spreading.

Most of the existing flame arresters are only provided with flame arresting elements, and the impact protection capability caused by sudden fuel detonation is low.
