Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 and fig. 2, the gas burner for drying tobacco leaves of the present invention comprises a split burner 1 with a mixing cone (not shown), an air pipe 2 for supplying air to the split burner 1, and a gas pipe 3 for supplying gas to the split burner 1, wherein the air pipe is provided with a combustion fan 21, a wind pressure switch 22 and an automatic butterfly valve 23, the gas pipe 3 is provided with a gas filter 31, the split type burner comprises a main fire electromagnetic valve 36, a proportional butterfly valve 37 and a first pressure regulating valve 38, a large fire regulating pipeline 4 and a small fire regulating pipeline 4 are arranged between an inlet node of the main fire electromagnetic valve 36 and an inlet of the split type burner 1, a main fire safety electromagnetic valve 41 and a second regulating valve 42 are arranged on the large fire regulating pipeline 4, the opening degree of the automatic butterfly valve 23 and the opening degree of the proportional butterfly valve 37 are controlled and linked by a servo motor 39, and an ignition electrode 12 controlled by an ignition transformer 11 is arranged in the split type burner 1. The fuel gas is filtered by the fuel gas filter 31 and pressure-regulated by the first regulating valve 38, and then enters the split type burner 1, the air is driven by the combustion fan 21 and pressure-regulated by the air pressure switch 22, and then enters the split type burner 1, and the ignition electrode 12 ignites the mixed fuel gas and air. Because the split burner 1 has the mixing cone, the combustion requirement of small fire can be met. The first pressure regulating valve 38 can control the maximum intake amount of air, and stabilize combustion. The automatic butterfly valve 23 and the proportional butterfly valve 37 which are linked can control the air and the fuel gas to be mixed in the same proportion on the premise of ensuring the sufficient combustion, thereby realizing the size control of the main fire. When a big fire is required to burn, the main fire electromagnetic valve 36 and the main fire safety electromagnetic valve 41 are opened, the servo motor 39 enables the proportional butterfly valve 37 to be opened to the maximum, the main fire is the maximum, and the main fire also burns; when the temperature reaches the heat preservation temperature, the servo motor 39 enables the proportion butterfly valve 37 to be adjusted to the minimum, and the main fire is reduced; in the combustion process, the pilot fire safety electromagnetic valve41 can be in an open state, the main fire keeps burning with low energy consumption for a long time, and the main fire can be opened at any time, so that larger temperature fluctuation caused by unsuccessful ignition of the main fire is avoided. The minimum fire of the burner can be 0.37-0.5m natural gas3Stable combustion at a maximum of 6-9m3The combustion is stable, the big and small fire can be switched freely, and the temperature control is accurate.
As shown in fig. 1, the combustion fan 21, the wind pressure switch 22, the gas pressure switch 34, the main fire solenoid valve 36, the servo motor 39 and the pilot fire safety solenoid valve 41 are controlled by an electric cabinet 5. Therefore, the full-automatic control can be realized by switching the big fire and the small fire of the gas burner.
The electric cabinet 5 detects the combustion condition by a flame detector (not shown) located in the split burner. The flame detector can monitor the combustion condition in real time so as to ensure that the temperature of the drying kiln is in a proper range and the firepower output is more accurate.
As shown in fig. 2, a main fire safety electromagnetic valve 35 controlled by the electric control box 5 is also arranged in front of the inlet of the main fire electromagnetic valve 36. If the flame detector finds that the combustion is too large and the control is lost, the main fire safety electromagnetic valve 35 can be operated to completely cut off the supply of fuel gas, so that the combustion at two places can be stopped emergently, and the flame detector can be maintained by people for safe use.
As shown in fig. 2, the gas pipe 3 is further provided with a pressure reducing valve 32 and a micro-pressure gauge 33 provided at an outlet node of the pressure reducing valve 32. The pressure reducing valve 32 can reduce the pressure of the high-pressure fuel gas into more controllable medium-pressure fuel gas, and the micro-pressure gauge 33 can display the pressure of the reduced fuel gas.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
