Description
Technical field
The invention belongs to mixed steam stove technical field, and steam stove is mixed more particularly to a kind of burning with even gas distribution device,
Suitable for dry materials, pre- thermal medium etc..
Background technology
In the industrial production, many places are required for that material is dried using medium temperature or high-temperature flue gas, or to air,
The media such as coal gas are preheated, to obtain higher ignition temperature.By taking blast fumance as an example, furnace coal spraying technology is to save Jiao
Charcoal, reduce the key technology of energy consumption., it is necessary to which coal dust is dried using heat smoke before coal powder injection, to ensure injection process
It is safe and stable, efficient.Pulverized coal injection has strict limitation for the temperature of drying flue gas, oxygen content, in order to fully reclaim
Using the energy, typically using caused low-temperature flue gas after Combustion of Hot Air Furnace, with combustion furnace caused by high-temperature flue gas mix, obtain
The satisfactory medium temperature flue gas of temperature, oxygen content, coal dust is dried.
Mixed steam stove is mixed by high-temperature gas caused by burning fuel with other cryogenic gases, so as to provide temperature and flow
Constant gas.Existing mixed steam stove is all to produce high-temperature gas in stove combust fuel, and cryogenic gas is from shaft surrounding with not
Spout with form enters, so as to realize mixing.The shortcomings that this mixed gas mode, is that high-temperature flue gas exists in center, cryogenic gas
Periphery, therefore occur that gas mixing is uneven, the phenomenon that peripheral temperature is low, central temperature is high, mixed gas must be through
Temperature could be gradually uniform after crossing the flowing of a segment distance, and not only increase investment, is also often subject to the restriction of Ground arrangement, shadow
Ring operational effect.
The content of the invention
, can by even gas distribution device the invention reside in providing a kind of burning with even gas distribution device to mix steam stove
Will burning caused by high-temperature flue gas carry out quadratic distribution, it is quickly mixed with cryogenic gas, so as to realize avoid central high temperature,
The purpose of mixing distance is reduced, not only reduces the volume of combustion furnace, and avoid the High Temperature Gas fluidization tower at center to pipeline valve
Destruction caused by the equipment such as door.
The present invention includes burner inlet 1, combustion chamber 2, even gas distribution device 3, cryogenic gas entrance 4, spout 5, mixed gas
Room 6, flame retardant coating 7, mixed gas outlet 8, qi-emitting hole 9, low-temperature flue gas circuit 10.Gaseous mixture entrance 1 is connected with external burner.
Combustion air and fuel gas enter combustion chamber 2 from burner inlet 1, and flowing, burning occur inside combustion chamber 2.Produced after burning
Raw high-temperature flue gas enters mixing chamber 6 through the qi-emitting hole 9 on even gas distribution device 3.Low-temperature flue gas enters from low-temperature flue gas entrance 4
Low-temperature flue gas circuit 10, enter mixing chamber 6 through spout 5.In mixing chamber 6, from the high-temperature flue gas that qi-emitting hole 9 sprays with from spout
5 low-temperature flue gas sprayed mutually mix, and obtain the gas that temperature meets to require, enter follow-up pipeline by mixed gas outlet 8
With equipment.
In summary, this burning mix steam stove the advantages of be：
1) even gas distribution device 3 is employed, the air-flow inside combustion chamber 2 can be reformed, is avoided due to burning
Device overheavy firing and caused by the factor such as flow rotation, vortex so that the gas flowing into mixing chamber 6 becomes controllable and equal
It is even.
2) gas passes through the qi-emitting hole 9 on even distribution device 3, it is possible to achieve to the secondary distribution of high-temperature gas, avoids the occurrence of
Central high temperature air-flow, the position of qi-emitting hole 9 is adjusted according to the distribution situation of the cryogenic gas entered by spout 5, so as to realize pair
The reinforcing mixing of high and low temperature gas, reduces the volume requirement to mixing chamber 6.
3) even gas distribution device is utilized, combustion chamber 2 and mixing chamber 6 can also clearly be demarcated, to the effective insulation in combustion chamber
Avoid putting out a fire, further improve security and stability；
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present invention.Wherein, burner inlet 1, combustion chamber 2, even gas distribution device 3, low
Warm gas access 4, spout 5, mixing chamber 6, flame retardant coating 7, mixed gas outlet 8, low-temperature flue gas circuit 10.
Fig. 2 is Fig. 1 A to cross section view.Wherein, even gas distribution device 3, qi-emitting hole 9.
Fig. 3 is Fig. 1 B-B direction view.Wherein, cryogenic gas entrance 4, spout 5, low-temperature flue gas circuit 10.
Embodiment
Fig. 1, Fig. 2, Fig. 3 are the embodiments of the present invention.
From Fig. 1~Fig. 3, the present invention enters including burner inlet 1, combustion chamber 2, even gas distribution device 3, cryogenic gas
Mouth 4, spout 5, mixing chamber 6, flame retardant coating 7, mixed gas outlet 8, qi-emitting hole 9, low-temperature flue gas circuit 10.
Burner inlet 1 connects external burner and combustion chamber 2, make the mixed gas of air and coal gas spray into
