Description

Technical Field

[0001] The utility model relates to a self-sufficient gas source auxiliary drying system for a burner ignition gun. Background Art

[0002] Gas water heaters have burners, and burners are equipped with independent ignition systems. The ignition gun is an important device in this system, which is used to ignite a small flame during the start-up of the burner. When the burner stops operating, its internal temperature drops from a hot state to a cold state, and the water vapor formed by combustion cannot be completely discharged. The water vapor condenses into water at the ion probe at the end of the ignition gun and forms a humid environment, resulting in the ion probe in the ignition gun being unable to generate an excitation arc when the burner is started, so that the gas cannot be ignited, resulting in the failure of the burner to start.

[0003] In summary, a burner ignition gun self-sufficient gas source auxiliary drying system is needed to solve the above problems. Utility Model Content

[0017] Reference Figure 1 A self-sufficient gas source auxiliary drying system for a burner ignition gun comprises an air and natural gas mixer 3, the output end of the air and natural gas mixer is connected to the rear of the ignition gun 1 through a mixed gas hose 2, the input end of the air and natural gas mixer is connected to a compressed air main pipe 4 and a natural gas main pipe 5, the compressed air main pipe is connected to the mixed gas hose through a drying pipe 6, a manual valve 7 is installed on the drying pipe, and the natural gas main pipe is connected to the middle of the ignition gun through a natural gas hose 8.

[0018] The compressed air main pipe is sequentially installed with a pressure reducing valve A9, a pressure gauge A10, a solenoid valve A11, and a filter screen A12-1, wherein the solenoid valve 11 can change its position.

[0019] The natural gas main pipe is sequentially installed with a solenoid valve B11-1, a solenoid valve C11-2, a pressure reducing valve B9-1, a pressure gauge B10-1, and a filter screen B12-2, wherein the solenoid valve B11-1 and the solenoid valve C11-2 can change their positions.

[0020] The natural gas hose is installed with a ball valve 13 and a filter screen C12-3.

[0021] Working principle:

[0022] Before starting the water heater burner, open the manual valve on the drying tube for 5 minutes of purge to ensure that the ion probe at the head of the ignition gun is in a dry environment. When the water heater burner is ignited and started, part of the natural gas and compressed air are released simultaneously according to the designed ratio, or the flow is controlled by a proportional valve, and enters the air and natural gas mixer through the natural gas mother pipe and the compressed air mother pipe. The mixed gas enters the rear of the ignition gun through the mixed gas hose, and the other part of the natural gas enters the middle of the ignition gun through the natural gas hose, and is mixed with the air and gas mixed gas again inside the ignition gun. At the same time, the control system controls the ignition electrode to generate an arc at the ion probe at the head of the ignition gun, thereby completing the ignition.
