Abstract

The invention belongs to the field of oil fume purification and is used for the oil fume purification of range hoods. The ultrasonic atomizer communicates with the combustion chamber through a pipe, and a pipe fan and a gas mixing chamber are connected in series on the pipe. An ignition device is installed in the combustion chamber, and the above components together form a combustion device; the combustion device is connected with the smoke exhaust pipe of the range hood. The present invention as a whole. The oil fume enters the intersection chamber from the exhaust pipe, where the atomized fuel generated by the ultrasonic atomizer mixes with the oil fume to become combustible oil fume, and the fully mixed combustible oil fume enters the combustion chamber and is ignited by the combustion chamber. When the device is ignited, the combustible oil fume is fully burned, the fume particles are burned out, and the remaining clean gas is discharged from the pipe outlet. The most prominent innovation of the present invention is that liquid fuels such as methanol and ethanol are atomized by ultrasonic waves, and the atomized fuel fully wraps the soot particles. When the atomized fuel is ignited, the soot particles are also burned instantly. Therefore, by adopting the solution of the present invention, the oil fume is thoroughly purified, and is close to maintenance-free.

Background technique

At present, the oil fume purification of range hoods mainly adopts centrifugal deoiling technology, but the purification effect of this method is not ideal, and the structure is complex and the failure rate is high. The present invention is designed aiming at the defects of the current oil fume purification technology.

The ultrasonic atomizer communicates with the combustion chamber through a pipe, and a pipe fan and a gas mixing chamber are connected in series on the pipe. An ignition device is installed in the combustion chamber, and the above components together form a combustion device; the combustion device is connected with the smoke exhaust pipe of the range hood. The present invention as a whole. The oil fume enters the intersection chamber from the exhaust pipe, where the atomized fuel generated by the ultrasonic atomizer mixes with the oil fume to become combustible oil fume. The fully mixed combustible oil fume enters the combustion chamber and is ignited by the combustion chamber. When the device is ignited, the combustible oil fume is fully burned, the oil fume particles are burned out, and the remaining clean gas is discharged from the pipe outlet.

The specific technical solution adopted to realize the present invention is that the ultrasonic atomizer communicates with the combustion chamber through a pipeline, a pipeline fan and an air mixing chamber are connected in series on the pipeline, an ignition device is arranged in the combustion chamber, and the above components together form a combustion device; The outlet of the smoke exhaust pipe of the range hood is connected with the pipeline of the combustion device, and the intersection of the outlet of the smoke exhaust pipe and the outlet of the ultrasonic atomizer is an intersection cavity, and the intersection cavity is connected with the ultrasonic atomizer, the combustion chamber and the smoke exhaust pipe at the same time. The outlet, the lower port of the range hood fan on the range hood is the oil fume inlet, the upper port of the range hood fan is connected to the exhaust pipe; the lower port of the range hood fan on the range hood sucks the oil fume, and the oil fume enters the intersection cavity from the exhaust pipe, and at the intersection At the cavity, the atomized fuel produced by the ultrasonic atomizer is mixed with the oil fume to become combustible fuel fume, and the combustible fuel fume enters the gas mixing chamber. The inside of the chamber is fully mixed due to the swirling motion, and the fully mixed combustible oil fume enters the combustion chamber and is ignited by the ignition device in the combustion chamber. .

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing.

In the figure, the combustion device 7 is an independent whole, and the combustion device 7 is connected with the smoke exhaust pipe 9 of the range hood 8 at any time to form an ultrasonic atomization product for removing the range hood oil fume.

The combustion device 7 and the range hood are designed as a whole.

In Fig. 1, the ultrasonic atomizer 1 communicates with the combustion chamber 3 through the pipeline 2, and the pipeline fan 4 and the gas mixing chamber 5 are connected in series on the pipeline 2, and the ignition device 6 is arranged in the combustion chamber 3, and the above components together form a combustion device 7. The outlet of the smoke exhaust pipe 9 of the range hood 8 communicates with the pipeline 2 of the combustion device 7, and the intersection of the outlet of the smoke exhaust pipe 9 and the outlet of the ultrasonic atomizer 1 is an intersection cavity 10, and the intersection cavity 10 communicates with the ultrasonic mist at the same time The outlet of the carburetor 1, the combustion chamber 3 and the exhaust pipe 9, the lower port 12 of the range hood fan 11 on the range hood 8 is the inlet of the oil fume 13, and the upper port 14 of the range hood fan 11 is connected to the exhaust pipe 9; The oil fume 13 is inhaled by the lower port 12 of the range hood fan 11, and the oil fume 13 enters the intersection chamber 10 from the exhaust pipe 9, and at the intersection chamber 10, the liquid fuel 18 in the ultrasonic atomizer 1 is atomized supernaturally, and the generated mist Combustible fuel 15 is mixed with soot 13 to become combustible fuel fume 16, and combustible fuel fume 16 enters the gas mixing chamber 5. Since the gas mixing chamber 5 is a chamber whose cross section is significantly larger than that of the pipe 2, the combustible fuel fume 16 is in the gas mixing chamber 5. The inside is fully mixed due to the swirling motion, and the fully mixed combustible oil fume 16 enters the combustion chamber 3 and is ignited by the ignition device 6 in the combustion chamber 3. 17 is discharged from the pipe 2 port.

It should be noted that the product formed by the present invention can be made of the combustion device 7 as an independent product, or can be integrated with the combustion device 7 and the range hood 8 . The liquid fuel used in the ultrasonic atomizer is preferably alcohol fuel such as methanol, ethanol and the like.
