Abstract

The present invention relates to a gas generator for aerosol fire-extinguishing agent, and its structure consists of base seat, chemicals cylinder, isolating cylinder and outer jacket. When said structure is used by matching it with smoke-producing agent and cooling agent, it can greatly reduce the temperature of smoke-producing agent and shell body.

Description

The aerocolloidal gas generator of a kind of generation
When the present invention relates to use aerosol extinguishing agent to put out a fire, the device of relevant gas generator.
As everyone knows, when putting out a fire with aerosol extinguishing agent, the flame and the heat that form during the firework medicament burning have a significant impact the extinguishing chemical effect, and might cause second-time burning, and existing gas generating unit is not that constructing too simple and crude is exactly that efficient is low.
The objective of the invention is to seek a kind of effective gasifier apparatus, when itself and smoke agent, when cooling agent is used, can reduce the temperature of smoke agent and the temperature of housing significantly.
The objective of the invention is to realize by following technical solution, this gas generator comprises base, cartridge case, every tube, overcoat, attaching plug etc.The gas passage of this gas generator is made up of combustion chamber, first cooling chamber, second cooling chamber and spout.
Description of drawings is as follows:
As shown in the figure, this gas generator is by base (11), cartridge case (9), form every tube (4), overcoat (1), several big of attaching plug (8).
Base (1) be connected with bolt between (1) every tube (4), overcoat, the claw that base (11) bottom has three equal angles to distribute plays the effect that gas generator is fixing.Between base (11) and cartridge case (9), heat shield (10) is housed.Cartridge case (9) is housed, dress pharmaceutical aerosol and igniter pad in the cartridge case (9) in tube (4).Middle part several reinforcing bars of equidistant welding (5) in tube (4), cartridge case (9) is securely fixed between base (1) and the reinforcing bar (5), constitutes the combustion chamber between medicament upper surface and the reinforcing bar (5) in the cartridge case.Equidistantly distribute movable reinforcing bar (3) every tube (4) top, the metal or the nonmetal coolant of powdery, column or pearl is being housed between reinforcing bar (5) and (3), constituting first cooling chamber.Every the equidistant bonding jumper that is welding tens of thick 0.1~5mm in tube (4) outside, between the inwall of the periphery of tube (4) and overcoat (1), constituted second cooling chamber.Overcoat (1) is a round barrel shape, and rectangle gas outlet (15) is arranged at its bottom, and gas outlet (15) are gone up and covered woven wire (16), and attaching plug (8) is set in the side-lower of overcoat (1).Overcoat (1) top inner surface is equipped with heat shield (2), scribbles certain thickness insulating moulding coating at overcoat (1) inwall.
When fire extinguishing, starting current is lighted igniter pad and pharmaceutical aerosol by plug (8) and lead (14), and medicament fully burns in the combustion chamber, has the combustion chamber in enough spaces to exist, and can increase substantially aerocolloidal output, and corresponding raising fire-fighting efficiency.
Aerosol cloud is after the combustion chamber forms, and through first cooling chamber, burned flame is blocked substantially, and the aerosol cloud temperature is reduced significantly; Smog is when second cooling chamber, and the bonding jumper (13) on tube (4) outer wall can absorb the heat of aerosol cloud in a large number.Contain a large amount of combustion residues in the aerosol cloud, these residues are being stopped by woven wire (16) by spout (15) is preceding, have guaranteed to reach instructions for use from the aerosol that the spout ejection is gone.

Claims (6)

  1. The aerocolloidal gas generator of a kind of generation
    1. one kind produces aerocolloidal gas generator, comprises base (11) cartridge case (9), every tube (4) and overcoat (1).
  2. 2. gas generator as claimed in claim 1 is characterized in that having the combustion chamber (6) of certain space.
  3. 3. gas generator as claimed in claim 1 is characterized in that first cooling chamber that coolant (12) is housed that constitutes between reinforcing bar (3) in tube (4) and (5).
  4. 4. according to claim 1, constitute second cooling chamber every the periphery of tube (4) and the interlayer of overcoat (1) inwall.
  5. 5. as described in the claim 4, the coolant of second cooling chamber is made up of the thick bonding jumper of 0.1~5mm that is welded on tube (4) outer wall.
  6. 6. according to claim 1, the inwall of overcoat scribbles insulating moulding coating, and the lower surface at the overcoat top has heat shield; Deposit between base (11) and the cartridge case (9) heat shield is housed.
