Embodiment Construction

[0020] see figure 1 In this embodiment, from the oil fume inlet 1 to the oil fume outlet 2, the oil fume purifier 3, the expansion muffler section 4 and the resistive muffler section 5 are sequentially arranged in series, wherein the expansion muffler section 4 is in the shape of an "L" elbow.

[0021] Catering fume is a mixture of volatile oils, organic matter, and thermal oxidation and thermal cracking during food cooking and food processing, and there are nearly a hundred compounds. Cooking fume includes three phases of gas, liquid, and solid. The particle size of liquid-solid particles is generally less than 10 μm. The mixture of liquid-solid particles has strong adhesion, most of them are insoluble in water, and have low polarity. The anti-oil mist measures specifically adopted in this embodiment include:

Abstract

This invention relates to oil smoke draught compound noise elimination device, which is characterized by series locating oil smoke purifier, expanding noise elimination section and resistant elimination section from oil smoke entrance to the exit. The invention adopts the combination of the expanding and resistant noise elimination technique and uses the characteristics of high frequency property of resistant noise elimination device and the good property of the expanding noise elimination device in low and middle frequency to make the invention with good noise elimination property in low and middle and high frequency bands.

Description

Technical field: [0001] The invention relates to a cooking oil fume extraction device, more particularly to a cooking oil fume extraction device with a sound-absorbing function. Background technique: [0002] Noise pollution complaints from the catering industry have always been the main aspect of urban environmental pollution disposal. For the noise reduction treatment of this kind of noise, factors such as oil smoke prevention and high temperature resistance must also be considered. It is precisely because of the mutual constraints of these factors. For a long time, the noise pollution in the back hall of the catering industry has not been well resolved. Invention content: [0003] The technical problem to be solved by the present invention is to avoid the deficiencies of the above-mentioned prior art, and to provide a composite muffler for oil fume exhaust and ventilation. The requirements of the use function, and the noise passing through it (including fan noise, gas ...
