Description

Technical Field

[0001] The present invention relates to the technical field of gas generators, and in particular to a gas generator set pre-gas supply device. Background Art

[0002] A gas generator is a generator that uses combustible gas as fuel. It can convert the heat energy generated by the combustion of fuel into mechanical energy, and then convert the mechanical energy into electrical energy through the generator. When in use, the gas engine needs to transport gas and air into its combustion chamber for combustion. After the gas is burned, a large amount of exhaust gas (mainly carbon dioxide) will be generated. These exhaust gases will carry a large amount of heat and be directly discharged into the air, resulting in heat waste. At present, the air inhaled by the gas generator is room temperature air. After the room temperature air is mixed with the gas, the combustion efficiency is general, and the heat of the gas cannot be completely released, resulting in waste. Therefore, in view of the above situation, it is urgent to develop a gas generator set pre-air supply device that uses the exhaust gas discharged by the gas engine to preheat the inhaled air and improve the energy utilization rate, so as to overcome the shortcomings in current practical applications and meet current needs.

A gas engine body 1 is provided on the ground on one side of the gas engine body 1. The preheating box 2 and the filter box 3 are provided with a preheating box 2 and a filter box 3. The preheating box 2 is filled with water. The heat exchange tube 8 is installed in the preheating box 2. The heat exchange tube 8 is connected to the air input tube 102. The heat exchange tube 8 is made of copper to have good thermal conductivity. An air outlet 201 is arranged on the top of the preheating box 2. The booster pump 4 is arranged on the ground.

The exhaust end of the booster pump 4 is connected to the exhaust gas outlet pipe 6. The bottom of the preheating box 2 is provided with an exhaust gas dispersion mechanism 7 extending to the interior thereof. The exhaust gas dispersion mechanism 7 is connected to the exhaust gas outlet pipe 6. An air inlet hole 301 is arranged on the right side of the filter box 3. Two dust filters 10 are fixed in the filter box 3. The two dust filters The mesh of the filter screen 10 located on the left side is smaller than that of the one on the right side, so as to perform double filtration and fully remove dust. The compressor 9 is set on the ground. The air inlet end of the compressor 9 is equipped with an air intake pipe 902 connected to the filter box 3, and the air outlet end of the compressor 9 is equipped with an air delivery pipe 901 connected to the heat exchange pipe 8.

When in use, the compressor 9 absorbs external air, and the external air enters from the air inlet hole 301, and the dust in the air is filtered out by the dust filter screen 10. Then, the compressor 9 delivers the air to the heat exchanger 8. In the heat exchange tube 8, air is transported to the gas engine body 1 through the heat exchange tube 8, and then the gas enters the gas engine body 1 from the gas input pipe 101. The high-temperature exhaust gas generated after the gas and air are mixed and burned is discharged from the exhaust gas discharge pipe 103, and then the high-temperature exhaust gas is transported to the exhaust gas dispersion mechanism 7 through the booster pump 4, the exhaust gas suction pipe 5, and the exhaust gas outlet pipe 6. The exhaust gas dispersion mechanism 7 discharges the exhaust gas into the preheating box 2 to heat the water, and the exhaust gas is finally discharged from the outlet 201. The hot water heats the air in the heat exchange tube 8, thereby increasing the temperature of the air entering the gas engine body 1.

When in use, the exhaust gas outlet pipe 6 transports the exhaust gas to the T-tube 704, and then the plurality of air outlet nozzles 705 discharge the exhaust gas into the water in the preheating box 2. At the same time, the first motor 701 drives the first gear 702, the second gear 703, the T-tube 704, and the air outlet nozzle 705 to rotate, so that the exhaust gas is more fully in contact with the water flow, so that the water flow absorbs the heat in the exhaust gas more fully.

[0023] The automatic dust cleaning mechanism 12 includes: a transmission shaft 1201, an eccentric cam 1202, a synchronous wheel 1203, a synchronous belt 1204 and a second motor 1205. The filter box 3 is rotatably connected to two transmission shafts 1201, each transmission shaft 1201 is located at the rear side of a dust filter 10, and each transmission shaft 1201 is fixed with a plurality of eccentric cams 1202.

The dust filter 10 is vibrated by the rotation of the eccentric cam 1202, so that the dust on the dust filter 10 falls off under the vibration and is discharged from the bottom of the filter box 3.

[0024] Working principle: When the pre-gas supply device of the gas generator set is in use, the compressor 9 absorbs external air, the external air enters from the air inlet 301, and the dust in the air is filtered out by the dust filter 10, and then the compressor 9 transports the air to the heat exchange tube 8, and then the air is transported to the gas engine body 1 through the heat exchange tube 8, and then the gas enters the gas engine body 1 from the gas input pipe 101, and the high-temperature exhaust gas generated after the gas and air are mixed and burned is discharged from the exhaust gas discharge pipe 103, and then the high-temperature exhaust gas is transported to the T-tube 704 through the booster pump 4, the exhaust gas suction pipe 5, and the exhaust gas outlet pipe 6, and then the exhaust gas is discharged into the water in the preheating box 2 through multiple exhaust nozzles 705. At the same time, the first motor 701 drives The first gear 702, the second gear 703, the T-tube 704, and the air outlet nozzle 705 rotate, so that the exhaust gas and the water flow contact more fully, so that the water flow absorbs the heat in the exhaust gas more fully to form hot water, and the hot water heats the air in the heat exchange tube 8, thereby increasing the temperature of the air entering the gas engine body 1. The high-temperature air and the gas are mixed with each other for higher combustion efficiency, thereby improving the energy utilization rate; when cleaning, first remove the inspection plate 11, and then drive the transmission shaft 1201 and the eccentric cam 1202 to rotate through the second motor 1205, and the dust filter 10 is vibrated by the rotation of the eccentric cam 1202, so that the dust on the dust filter 10 falls off under the vibration and is discharged from the bottom of the filter box 3.
