Description
Technical field
The present invention relates to the combustion chamber dress of a kind of combusting room device, more particularly to a kind of large area disinfectant anti-epidemic equipment
Put.
Background technology
At present, the form of combustion chamber is a lot, and the combustion chamber of heating burning, such as boiler, heating are directed in heater
Stove etc., is also widely used in the heating combustion chamber of the combustion chamber such as Aeronautics and Astronautics of the heating system of mobile device.And in big face
, it is necessary to which disinfecting drug is heated to after certain temperature equably to spray large-area smog in the disinfectant anti-epidemic equipment of product smog formation
It is spread across in the air, plays a part of epidemic prevention.From the former combustion chamber, although low cost, but its huge structure, being unfavorable for movement makes
With.The latter is conducive to using, but requires that manufacture is accurate, involves great expense, use cost is higher.The mobile spray used both at home and abroad at present
Mainly there are two classes mist equipment combustion chamber, and a class is the toroidal combustion chamber of miniature gas turbine formula smoke equipment, such as：French SG18 hairs
The combustion chamber of cigarette equipment；Another kind of is common throat less chamber, such as：The combustion chamber of all kinds of burners.
The toroidal combustion chamber of miniature gas turbine formula smoke equipment, constitutes annular airflow by the inside and outside housing of combustion chamber and leads to
What is installed in road, passage is an annular flame tube being made up of inside and outside wall, burns to enter in the combustion zone and dilution zone of annular
OK.The chamber structure is complicated, higher to the performance requirement of air pressure and material.It is mainly used in aviation field and miniature smoke dress
It is standby.
Common throat less chamber is due to simple in construction, and because gas pressure is smaller, the flame of formation is very long, causes burning
The dilution zone of room is very long, considerably increases the overall length of combustion chamber, is unfavorable for movement.
The content of the invention
The purpose of the present invention is in summary advantage, above-mentioned defect is overcome, so as to design one kind of hollow formula
The combusting room device of large-area smog disinfectant anti-epidemic equipment.
A kind of combusting room device of large-area smog disinfectant anti-epidemic equipment of the present invention includes burner inner liner, diffuser, point gas

Air-flow carries out reasonable distribution, and point stomata is row's ring trapezoidal hole.Mounting hole is mounting hole symmetrical above and below, and mounting hole is used to fix
With the other parts of installation.
The annular cavity of described cold air set be formed by the shape of combustor outer casing body by combustion chamber external diameter annulus section,
Changeover portion and spout annulus section composition are restrained, the velocity heated gas after being blended for water conservancy diversion protects shell.Cut in the outlet of spout
There is the air-flow in row's cooling air-flow steam vent, the annular cavity of discharge cold air set on face.
Described combustion gas set is the outside for connecting and being enclosed on burner inner liner, extends directly into the centre of tempering cylinder.Combustion gas
Set is divided into import annulus section, converging portion changeover portion and blending burning zone, and in the nozzle formation convergence cone of blending burning zone
Degree.In one mounting flange of outside weldings of import annulus section.
Described tempering cylinder includes one section of annulus section and the conical ring section structure tangent with bulb.Ball head structure changes
The direction of combustion gas, makes combustion gas cover the region to be formed backflow from tempering cylinder and combustion gas.
Described burner inner liner, diffuser, air distribution disk, combustion gas set, tempering cylinder and cold air set inwall and combustor outer casing body are all
It is using installation with one heart.
Air enters from diffuser, is partly into combustion chambers burn, area of the part between burner inner liner and combustion gas set
Domain enters, and is tentatively blended with thermal-flame, and a part enters from point stomata on air distribution disk, the high temperature come with tempering cylinder backflow
Region blending of the air-flow in cold air set, the velocity heated gas suitably sprayed, the disinfectant formation smog of input sprays
Mouthful.
Due to using above-mentioned technical proposal, make the invention has the advantages that and effect：
Chamber structure is relatively simple, lightweight, is easy to movement.
Combustion chamber is hollow structure, adds the stroke of combustion gas and the time of blending, substantially reduces the length of general structure
