Abstract

The invention discloses a spiral plate-type heat tube flame arrester. The spiral plate-type heat tube flame arrester comprises a fireproof shell and a heat tube, wherein the fireproof shell is in a cylindrical shape, the bottom of the fireproof shell is provided with a base, and the top of the fireproof shell is provided with a cover body; and a spiral plate is arranged in the fireproof shell, thespiral plate is formed by connecting and winding a first metal plate and a second metal plate, a metal box body is formed on a welded part of the first metal plate and the second metal plate, the wound part of the first metal plate is wound outwardly surrounding the metal box body, the wound part of the second metal plate is encircled around the first metal plate by adopting the metal box body asthe center, and a first spiral runner and a second spiral runner are formed between the wound part of the first metal plate and the wound part of the second metal plate. The spiral plate is arrangedin the fireproof shell to form the spiral runner, so that the fireproof space is increased, the wall effect produced by the structural change of a multilayer channel is sufficiently used for sharply reducing the free radicals of the combustion, and the explosion is effectively prevented.

Description

technical field

[0001] The invention belongs to the technical field of fire arresting and explosion suppression, and in particular relates to a spiral plate heat pipe flame arrester. Background technique

[0002] Nowadays, the demand for energy is increasing day by day, modern industry is constantly developing along with the increase in energy demand, and the transportation of energy has become a very important part. In recent years, during the production and transportation of flammable liquids and gases, combustion and explosions often occur, which have adverse effects on people and the environment. Effective safety measures for fire and explosion protection are required. Coal-based energy has been extensively excavated, and the corresponding mining intensity and depth have been increasing, and the increase in the rate of gas explosion accidents has continuously threatened the safety of human life and the balance of the ecological environment. The technical measures to pre...
