A fire prevention device for preventing flue fire

Abstract

The invention discloses a fireproof device for preventing a smoke channel fire disaster and belongs to the technical field of fire fighting equipment. The fireproof device for preventing the smoke channel fire disaster is characterized by comprising baffles (2) arranged at the two ends of a smoke channel (1) and dry powder spray heads (11), the baffles (2) are detachably arranged at the two ends of the smoke channel (1) and close the two ends of the smoke channel (1), at least one side of the smoke channel (1) is provide with a powder spraying opening, the dry powder spray heads (11) are arranged on the outer side of the powder spraying opening, the dry powder spray heads (11) are connected with telescoping mechanisms, and the dry powder spray heads (11) are further connected with a powderinlet pipe (8). According to the fireproof device for preventing the smoke channel fire disaster, fireproof powder is sprayed into the smoke channel, the fireproof powder can attach to the oil face of the smoke channel wall after entering the smoke channel, and therefore the oil face is isolated from the air in the smoke channel, even when open fire is generated in the smoke channel, the fire disaster cannot be caused, the probability of the fire disaster is greatly reduced, the risks of the fire disaster in the smoke channel are reduced, and potential safety hazards are reduced.

Description

technical field [0001] A fire prevention device for preventing flue fire belongs to the technical field of fire protection equipment. Background technique [0002] A flue is a tubular passage for exhaust gas and smoke. Restaurants or residential buildings usually have a flue to facilitate the emission of oil fume. Since the oil in the lampblack will adhere to the inner wall of the flue, after long-term use, more oil will adhere to the inside of the flue, and it is easy to cause a fire when it encounters an open flame. The existing flue cleaning equipment only realizes the cleaning of the flue by spraying water into the flue. This inclined method cannot remove the oil attached to the inner wall of the flue, which leads to serious safety hazards in the flue. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a fire prevention device for preventing flue fires by adhering ...

Problems solved by technology

Because the oil in the lampblack will adhere to the inner wall of the flue, after a long time of use, more oil will adhere to the inside of the flue, and it is easy to cause a fire when it encounters an open flame

The existing flue cleaning equipment only realizes the cleaning of the flue by spraying water into the flue. This inclined method cannot remove the oil attached to the inner wall of the flue, which leads to serious safety hazards in the flue now.
