Description
Technical field
The invention belongs to industrial furnace equipment technical field, is related to a kind of three-dimensional conductive heat exchange type burner.
Background technology
Self-preheating type burner is a kind of very extensive continuous burning heater of heating art application, has low heat value
High-temp combustion, burning low NOX emission, it is safe and stable and energy saving the features such as, at present present in the burner of self-preheating type structure
Volume is bigger than normal, the defects of installation is inconvenient, heat conduction efficiency is low, heat easily loses and service life is shorter, this hair
It is bright that a kind of industrial kiln heat exchange type burner is provided, it is low-temperature burning field burner developing direction in future.
The content of the invention
For the present invention in view of the above-mentioned problems, providing a kind of three-dimensional conductive heat exchange type burner, which passes through multi-stage heat exchanger
Form, be fully warmed-up combustion air, achieve the purpose that it is energy-efficient, can be widely applied to heat treatment, non-ferrous metal it is indirect
Heating（Radiant tube）, suitable for workpiece cannot with the operating mode of certain atmosphere is special procured in smoke contacts or stove, be also applied for directly plus
Heat（Naked light burns）, in 500 DEG C ~ 1000 DEG C use temperature ranges, achieveed the purpose that by warm-up combustion-supporting air energy saving.
Technical solution according to the invention：A kind of three-dimensional conductive heat exchange type burner, it is characterised in that：Including heat exchanger,
Described heat exchanger axial direction one end is tightly connected burner, and the heat exchanger axial direction other end sets air intlet and exhanst gas outlet, air
Import is connected with the inlet channel in heat exchanger, and exhanst gas outlet is connected with the exhaust gases passes in heat exchanger；The burner
Interior arrangement plate, is provided with lug boss on plate；The burner upper end is equipped with fuel gas inlet and burner, the air inlet in heat exchanger
Passage connects fuel gas inlet, realizes the mixing of air and combustion gas after preheating, the inlet communication burning of the exhaust gases passes in heat exchanger
The exhanst gas outlet of device.
As a further improvement on the present invention, the burner lower end is tightly connected outer tube, and outer tube lower end is closing
Structure.
As a further improvement on the present invention, the axial direction of the heat exchanger and burner is axially vertical.
The technical effects of the invention are that：More perfect the invention enables air preheat, combustion of natural gas efficiency is more filled
Point, flame effect perfectionization.Burner has used 3 D stereo cross-exchange pattern in the present invention, makes air fully mixed with flue gas
Close so that heat conduction efficiency is completely abundant.3 D stereo cross-exchange pattern used herein also reduces smoke pollution at the same time
Thing discharges, and discharge is completely up to standard.By three-dimensional conductive heat exchange mode, the waste heat in high efficiente callback high-temperature flue gas, is made to combustion-supporting
Preheated with air, improve the temperature of preheated air.Exhaust gas temperature is reduced after three-dimensional heat exchange, reaches the effect of energy-saving and emission-reduction
Fruit.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the top view of Fig. 1.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1,2, including burner 1, lug boss 1-1, heat exchanger 2, outer tube 3, air intlet 4, exhanst gas outlet 5, combustion
Gas import 6, burner 7 etc..
As shown in Figure 1, 2, the present invention is a kind of three-dimensional conductive heat exchange type burner, including heat exchanger 2, the heat exchanger 2
Axial one end is tightly connected burner 1, and the axial other end of heat exchanger 2 sets air intlet 4 and exhanst gas outlet 5, air intlet 4 with
Inlet channel in heat exchanger 2 is connected, and exhanst gas outlet 5 is connected with the exhaust gases passes in heat exchanger 2；In the burner 1
Arrange plate, lug boss 1-1 is provided with plate；1 upper end of burner is equipped with fuel gas inlet 6 and burner 7, in heat exchanger 2
Inlet channel connection fuel gas inlet 6, realize the mixing of air and combustion gas after preheating, the import of the exhaust gases passes in heat exchanger 2
Connect the exhanst gas outlet of burner 1.
1 lower end of burner is tightly connected outer tube 3, and 3 lower end of outer tube is enclosed construction.
The axial direction of heat exchanger 2 is axially vertical with burner 1.
The course of work of the present invention is as follows：First the air intlet 4 through heat exchanger 2 enters through heat exchanger 2 and burning cold air
Later the flue gas produced is in 2 heat-shift of heat exchanger, and after being sufficiently mixed preheating, air is exported from high-temperature preheated air mouth, output
Combustion gas mixing that preheated air afterwards is passed through with fuel gas inlet 6 is simultaneously fully burnt.And the flue gas produced enters from high-temperature flue gas mouth
Heat exchanger 2 is discharged after circulating from exhanst gas outlet 5.Normal temperature air and heat smoke so alternately flow through heat exchanger heat-shift, empty
Gas can be fully warmed-up the effect for reaching energy saving, realize the perfect recycling of flue gas heat.The outer tube set again by burner 1
Thermal energy is then perfectly remained when 3 and more saves fuel.Analysis understands to obtain by three-dimensional conductive heat exchanger more than
The high temperature air of continuous-stable, reaches energy saving effect.
