Efficient flame retardant device

Abstract

The invention provides an efficient flame retardant device. The efficient flame retardant device is installed between a gas supply end and a client side, and sequentially comprises an electronic check valve, a water type flame retardant mechanism, a dry type flame retardant mechanism and a free radical detection device in the direction from the gas supply end to the client side, and the free radical detection device and the electronic check valve are electrically connected with a controller. According to the efficient flame retardant device, the water type flame retardant mechanism and the dry type flame retardant mechanism are connected in series, lots of free radicals in tempering flames can be eliminated through the dry type flame retardant mechanism, then, cooling is conducted through the water type flame retardant mechanism, and thus, shifting of the tempering flames can be thoroughly avoided; moreover, the front end of the efficient flame retardant device is additionally provided with the free radical detection device which adopts a mode that signals of the free radicals are amplified through copper wires, and then detecting is conducted, and accordingly, the sensitivity of the free radical detection device can be improved. Through the efficient flame retardant device, the flame retardant effect can be well achieved, and the safety of the gas source end is ensured.

Description

technical field [0001] The invention relates to the technical field of fire arresting devices in hydrogen-oxygen mixed gas delivery pipelines, in particular to a high-efficiency fire arresting device. Background technique [0002] In the process of using flammable gases, high-efficiency fire arresting devices are required. High-efficiency fire arresting devices, also known as fire prevention devices, are safety devices used to prevent the flame spread of flammable gases and flammable liquid vapors, and prevent equipment from flashing back Occasionally cause potential safety hazards at the gas source end.

Refer to the public document: A multi-stage stacked variable-diameter split flow anti-reflash tank device, publication number: CN106051466A, publication date: 2016-10-26, using multiple tanks filled with water in series to achieve fire resistance Purpose, but when the hydrogen fuel is backfired, the pressure increases rapidly, and the hydrogen molecules will generate a large number of free radicals to return to the direction of the gas source. The free radicals collide with other molecules to form new products and new free radicals. The radicals continue to react with other molecules, and the free radicals have the opportunity to pass through the tank through the gas channel in the liquid. Therefore, before the tempering seedlings enter the tank containing the liquid, a large number of free radicals produced by tempering must be removed. At the same time, for the sake of safety, an inspection device must be installed in the front of the high-efficiency fire arresting device, but because the number of free radicals is not large, it is difficult to detect, so it is difficult to cut off the gas source when the tempering just occurs
