Problems solved by technology

[0006] 1. Since the muffler uses only a single-layer sound-absorbing surface and is placed at the lower air outlet in the same plane as the filter air outlet, the unfiltered oil fume after the filter directly enters the muffler After a long time, the oil fume molecules will enter the sound-absorbing surface of the muffler, and then block the perforated plate on the sound-absorbing surface. noise reduction performance
[0007] 2. Due to space constraints, straight-line ventilation ducts are used to directly extend out of the building, which hinders the beauty of the external decoration of the building

Embodiment Construction

[0026] like figure 2 As shown, the exhaust and muffler device 1 for effectively reducing oil fume pollution of the present invention consists of a ventilation duct 2 with an air inlet 11 and an air outlet 12, a fan 3 installed in the ventilation duct 2, an air filter 4 and a noise reduction The device 6 constitutes.

[0027] It is suitable for installation in the exhaust system of commercial real estate, restaurants and industrial plants to exhaust indoor waste air to the outside.

[0028] 1. Ventilation duct 2

[0029] The ventilation duct 2 mainly guides the waste air in the room to flow from the air inlet 11 to the air outlet 12 and is discharged into the outdoor atmosphere. or made of fiberglass.

[0030] It is characterized in that its entire shape is "L"-shaped, that is, it is composed of two parts, namely an "L"-shaped horizontal part 21 (hereinafter referred to as the horizontal part 21) and an "L"-shaped vertical part 22 (hereinafter referred to as the vertical pa...

Abstract

The invention discloses an exhaust noise reduction device capable of effectively reducing oil smoke pollution. The device is characterized in that the space is reasonably utilized, the external decoration of the building is kept, and the service life of a noise absorbing device can be prolonged. The device comprises a ventilation pipeline, a fan, an air filter and the noise absorbing device for absorbing noise. The noise absorbing device and the air filter are arranged in different planes, a flow guide oil collection area with a flow guide piece is arranged between the noise absorbing device and the air filter, so that the removal capability of the exhaust noise absorbing device on oil stains in the waste air is greatly improved; and meanwhile, a silencer in the absorbing device also adopts further oil prevention and pollution discharge improvement, the oil removal capability is further improved, the pollution of the oil stains to the silencer is reduced, and the noise absorbing function of the silencer is avoided. A ventilating duct is L-shaped, so that the building external space can be reasonably utilized, the layout of the ventilating duct can be ensured when the ventilating duct extends out of the building. Due to the improvement of the oil removal capacity, the service life of the silencer in the exhaust noise absorbing device is greatly prolonged.

Description

technical field [0001] The invention relates to a large-scale oil fume extraction device, in particular to an oil fume discharge device with a muffler. Background technique [0002] Nowadays, exhaust devices are installed in many commercial real estates, restaurants and industrial plants, which can discharge indoor exhaust gas containing oily fumes (including cooking fumes and industrial electric welding). Such exhaust devices include air filters 4 and the muffler 7 (see figure 1 shown). [0003] This type of exhaust device is installed on the podium. This type of exhaust device in the prior art is composed of a linear ventilation duct 2, a fan 3, a filter and a muffler 7. Usually, the ventilation duct 2 adopts a horizontal direction Stretch out. [0004] The assembly structure of the exhaust device is as follows: the fan 3 is installed at the air inlet 11 where the ventilation duct 2 and the room are connected, the filter is installed in the ventilation duct 2 at a posit...
