Abstract

The invention discloses a high-pressure dried carbon dioxide powder fire extinguisher. A dried powder self-sucking mechanism comprises a mixing pipe, wherein a dried powder suction pipe is connected to a pipe wall of the mixing pipe; a carbon dioxide injection pipe is arranged inside the mixing pipe; the front end of the mixing pipe is connected with a mixing injection pipe; the rear end of the carbon dioxide injection pipe extends out of the rear end of the mixing pipe and is connected with a carbon dioxide bottle by virtue of a high-pressure delivery pipe; and the outer end of the dried powder suction pipe is connected with a dried powder fire extinguishing agent tank by virtue of a connecting pipe. The pressure in the carbon dioxide bottle is 6-7MPa or below, and the injection distance of the fire extinguisher disclosed by the invention is about 20meters. The injection time can be regulated according to the loading capacity of the dried powder fire extinguishing agent tank and the carbon dioxide bottle and can be more than ten minutes and tens of minutes.

Description

technical field [0001] The invention relates to a fire extinguisher, in particular to a fire extinguisher using a mixture of carbon dioxide and dry powder as a fire extinguishing material. Background technique [0002] Utilize the mixture of carbon dioxide and dry powder to make the existing fire extinguisher of fire extinguishing material, generally carbon dioxide and dry powder are mixed in the same container, control carbon dioxide and dry powder to spray together for fire extinguishing during use. Its main disadvantages are: first, the pressure is low and the spraying distance is short. According to relevant regulations, the internal pressure of the container reaches 1.5 MPa and the spraying distance reaches 9 meters to be qualified. Second, the injection time is short. According to the relevant regulations, the injection time reaches 25 seconds to be qualified. Contents of the invention [0003] The technical problem to be solved by the present invention is to provid...
