Specific embodiment
Invention is further described in detail combined with specific embodiments below.
Embodiment:
As depicted in figs. 1 and 2, a kind of tobacco leaf drying gas burner of the invention, including interior there is mixing cone (not draw
Split type burner 1 out) supplies the air pipeline 2 of air for split type burner 1 and is the combustion that split type burner 1 supplies combustion gas
Feed channel 3, air pipeline are equipped with combustion fan 21, blast switch 22 and automatic butterfly valve 23, and gas pipeline 3 is equipped with combustion gas
Filter 31, main thermoelectricity magnet valve 36, ratio butterfly valve 37 and the first pressure regulator valve 38, the Ingress node of main thermoelectricity magnet valve 36 and split type burning
It is equipped with large and small fire between the entrance of mouth 1 and adjusts pipeline 4, large and small fire adjusts pipeline 4 and is equipped with female fire safety solenoid valve 41 and second
Regulating valve 42, the aperture of automatic butterfly valve 23 and the aperture of ratio butterfly valve 37 are controlled by a servo motor 39 and are linked, split type burner 1
It is interior with the ignitor 12 controlled by ignition transformer 11.The filtering and the first regulating valve 38 of gas filter 31 are passed through in combustion gas
Pressure regulation after enter split type burner 1, air after the driving of combustion fan 21 and the pressure regulation of blast switch 22 enter point
Body formula burner 1, ignitor 12 lights mixed combustion gas and air.Because split type burner 1 has mixing cone,
It can satisfy the burning needs of small fire.First pressure regulator valve 38 can control the maximum inlet of air, make flameholding.Linkage
Automatic butterfly valve 23 and ratio butterfly valve 37 can control air and combustion gas and mix in proportion under the premise of guaranteeing burning adequately, realize
The size of main fire controls.When high fire being needed to burn, main thermoelectricity magnet valve 36 and female fire safety solenoid valve 41 are opened, and servo motor 39 allows
Ratio butterfly valve 37 opens to the maximum, and main fire is maximum, and female fire also burns；After reaching holding temperature, servo motor 39 allows ratio butterfly valve
37 are transferred to minimum, and main fire becomes smaller；In combustion, female fire safety solenoid valve 41 can in opened condition, and female fire is kept for a long time
The burning of low energy consumption, main fire can be opened at any time, avoid main fire igniting is unsuccessful from bringing biggish temperature fluctuation.This burner is most
Small fire can accomplish natural gas 0.37-0.5m3/ h stablizes burning, and most high fire is in 6-9m3/ h stablizes burning, and large and small fire free switching makes
With temperature control is accurate.
As shown in Figure 1, combustion fan 21, blast switch 22, gaseous-pressure switch 34, main thermoelectricity magnet valve 36, servo motor
39 are controlled with female fire safety solenoid valve 41 by an electric cabinet 5.This sample gas burner large and small fire switching may be implemented it is complete from
Dynamic control.
Electric cabinet 5 detects combustion case using the flame detector (not shown) being located in split type burner.Fire defector
Combustion position can be monitored in real time in device, to make the temperature of drying kiln in appropriate range, keeps firepower output more accurate.
As shown in Fig. 2, being additionally provided with the main fire safety solenoid valve 35 controlled by electric cabinet 5 before the entrance of main thermoelectricity magnet valve 36.
It is out of hand if flame detector discovery burning is excessive, the supply that main fire safety solenoid valve 35 thoroughly turns off combustion gas can be manipulated,
Burning at such two just can emergent stopping, et al. maintenance use safely again.
As shown in Fig. 2, being additionally provided with pressure reducing valve 32 and the micromanometer set on 32 Egress node of pressure reducing valve on gas pipeline 3
33.It is more controllable middle compression ignition gas that pressure reducing valve 32, which can allow the combustion gas of high pressure to be depressured, and micromanometer 33 can show the combustion after decompression
Atmospheric pressure.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
