It is generally installed in a pipeline that transports flammable gases, or on a ventilated tank. It is a device that prevents the spread of flames. It consists of a flame arrester core, a flame arrester shell, and accessories. One of the necessary conditions for combustion is to reach a certain temperature, namely the ignition point. Below the ignition point, combustion will stop. According to this principle, as long as the temperature of the burning material is lowered below its ignition point, the spread of the flame can be prevented. When the flame passes through many small channels of the flame arrester element, it will become several small flames. When designing the flame arrester element inside the flame arrester, the contact area between the small flame and the channel wall is expanded as much as possible, the heat transfer is enhanced, and the flame temperature is reduced below the ignition point, thereby preventing the flame from spreading. In order to improve the convenience of using the flame arrester, this application provides a detonation-proof flame arrester. The following problems exist in the prior art:
