Embodiment Construction

[0014] From Figure 1, image 3 An example of the present invention is given: a lampblack filter element used in a range hood mainly consists of three layers of high-efficiency adsorbent materials, and its specification is that the upper layer 1 is an inorganic polymer coke activated carbon adsorbent material with a diameter of 2-3cm ; The middle layer 2 is a carbon molecular sieve adsorption material with a diameter of 1-3cm; the lower layer 3 is a coke activated carbon adsorbent material with a diameter of 3-4cm. image 3 It is an oil fume filter element with a hole in the center.

[0015] In specific production, according to the raw material ratio of each component adsorbent required for making a 1000-gram oil fume filter element, it is calculated as:

[0016] Upper activated carbon adsorbent material 250-350 grams

[0017] Middle layer molecular sieve adsorbent material 150-250 grams

[0018] 350-400 grams of activated carbon adsorbent material in the lower layer.

Abstract

The present invention relates to the field of fume adsorbing and filtering technology. The fume-filtering element consists of three layers of efficient adsorbing material including the upper layer of inorganic high molecular active coke carbon adsorbent, the middle layer of carbon molecular sieve adsorbent, and lower layer of active coke carbon adsorbent. All the layers are packed and separated with non-woven fabric and installed in a porous plastic frame matched with kitchen ventilator. The present invention has simple structure, small volume, and no environmental pollution and has both physical and chemical adsorbing effects.

Description

technical field [0001] The invention belongs to the technical field of oil fume adsorption and filtration of range hoods, and in particular relates to an oil fume filter element used in range hoods. Background technique [0002] At present, commercially available range hoods have too high oil fume content in restaurants and kitchens in households and public places, which is a characteristic of kitchen cooking in our country. When the range hood is working, the inhaled oil fume is discharged through the air duct and the flue, and while part of it flows into the oil storage box, part of the oil is still attached to the inner wall of the fan, motor and bellows, forming a thick layer over time. Grease dirt, which not only increases the load on the motor, increases the noise, but also affects the exhaust air volume. Over time, oil leakage and oil throwing will occur. At the same time, harmful gases and substances in the pumping unit are discharged into the atmosphere , causing s...
