Description
Technical field
The utility model is related to a kind of hot-blast stove more particularly to a kind of fuel gas hot-blast stoves suitable for grain heat-drying.
Background technology
The length of existing fuel gas hot-blast stove combustion chamber is all long, this is because combusted gas generant in view of combustor
The length of flame is longer, and the length of furnace body will adapt to the length of flame, and furnace body is avoided to touch the flame of high temperature, make furnace body in high temperature
Carbonization is generated by heating under state, so as to shorten the service life of furnace body.But not only result in production after furnace body length increase
The increase of cost, floor space can also increase.
In addition, its temperature is excessively high, it is necessary to cool down, now when the hot wind after gas hot-air stove heat is used for grain heat-drying
Have that the heat sink structure used in technology is complex, while can also increase floor space.
Based on this reason, in order to extend converter life, and be unlikely to make furnace body long, waste of materials, thus it is new go out
A kind of fire-proof plate, particular for the long flame that the internal-combustion machine burning combustible gas of hot-blast stove generates, by selection, use is stainless
Steel 316L makes fire-proof plate, and the back-fire relief before flame allows the length of furnace body greatly to shorten, and furnace body uses the longevity
Life is unaffected, while heat can also be concentrated, and so as to save manufacture cost, economic benefit is brought to making side.
The content of the invention
The utility model provides a kind of fuel gas hot-blast stove, by liner (combustion chamber) fireguard being set to stop burning
The flame of machine ensures that the length of liner can be shortened while hot wind fully heats；Folder before hot wind extraction between inside and outside courage
With extraneous air hybrid cooling in layer, meet the requirement of temperature in use；Its is simple and compact for structure, easily manufactured, at low cost, takes up an area
Area is small.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of fuel gas hot-blast stove, including fuel gas hot-blast stove；The fuel gas hot-blast stove sets liner and outer courage, and the one side of liner is set
Combustor, the one side opposite with combustor set air-introduced machine；Liner sets hot air outlet, homonymy on the side wall of air-introduced machine one side
Outer courage side wall on set mixing wind air outlet, mixing wind air outlet connects the entrance of air-introduced machine by aspiration channel, and air-introduced machine goes out
Mouth connects subsequent drying equipment；Air inlet is set on outer courage, the inside of liner sets fire-proof plate at hot air outlet.
The fire-proof plate is made of Cone Disc and bar shaped gusset, and the tip of Cone Disc is towards combustor one side, and Cone Disc
Symmetrical centre and combustor burner center it is collinear；Multiple bar shaped gussets are uniformly arranged along the circumferential direction of Cone Disc, and Cone Disc leads to
Bar shaped gusset is crossed to be fixedly connected with liner.
The bottom of the liner sets support plate realization and the positioning and fixation of outer courage, and air inlet is arranged on the top of outer courage.
The liner is made of 316L stainless steel materials.
The outer courage is made of 304 stainless steel materials, and the outside of outer courage sets insulating layer.
The fire-proof plate is made of 316L stainless steel materials.
Compared with prior art, the beneficial effects of the utility model are：
1) by set in the liner (combustion chamber) fireguard stop the flame of combustor, flame turn back after in liner
Air comes into full contact with, and ensures that the length of liner can be shortened while hot wind fully heats；
2) temperature in use is met with extraneous air hybrid cooling in the interlayer before hot wind extraction between inside and outside courage
It is required that；
3) simple and compact for structure, easily manufactured, at low cost, floor space is small.
Description of the drawings
Fig. 1 is a kind of structure diagram of fuel gas hot-blast stove described in the utility model.
Fig. 2 is the structure diagram of fire-proof plate described in the utility model.
In figure：1. 2. liner of combustor, 3. 7. aspiration channel of outer 4. support plate of courage 5. fire-proof plate, 6. air inlet, 8. air-introduced machine
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of fuel gas hot-blast stove described in the utility model, including fuel gas hot-blast stove；The fuel gas hot-blast stove
If liner 2 and outer courage 3, the one side of liner 2 sets combustor 1, and the one side opposite with combustor 1 sets air-introduced machine 8；Liner 2 is close to be drawn
Hot air outlet is set on the side wall of 8 one side of wind turbine, sets mixing wind air outlet on 3 side wall of outer courage of homonymy, mixing wind air outlet leads to
The entrance that aspiration channel 7 connects air-introduced machine 8 is crossed, the outlet of air-introduced machine 8 connects subsequent drying equipment；Air inlet 6 is set on outer courage 3,
The inside of liner 2 sets fire-proof plate 5 at hot air outlet.
