This utility model discloses a low-resistance, high-efficiency oil fume filter, aiming to provide a low-resistance, high-efficiency oil fume filter that can effectively improve the problem of oil-water mixtures easily accumulating on the filter material layer, leading to a sharp decrease in the air permeability of the filter material layer, thereby extending the service life of the oil fume filter and reducing the energy consumption of the range hood. It includes: a shell, including a top cover, an outer frame located at the edge of the top cover, and an inner frame located inside the outer frame, with an annular groove formed between the outer frame and the inner frame, and a plurality of guide ports connected to the annular groove on the top of the inner frame, and a support mesh on the top cover; a bottom grille, including a plurality of grille bars connected to the bottom of the inner frame, with guide grooves on the grille bars opening upwards and communicating with the annular groove; and a filter structure located inside the inner frame, including a water-absorbing and oil-absorbing guide layer, an intermediate filter layer, and a bottom filter layer distributed in sequence, with the water-absorbing and oil-absorbing guide layer located at the top of the inner frame, and the bottom filter layer supported on the bottom grille.

This invention discloses a method for preparing a wood-based solar interface evaporator and its application, belonging to the field of solar evaporation seawater desalination technology. Using natural wood as raw material, a superhydrophilic wood aerogel (WA) is prepared through delignification and freeze-drying. MOF material is grafted onto the porous channel surface of WA using in-situ grafting technology to obtain MOF@WA. Porous lignin carbon (PLC) is prepared from lignin through high-temperature carbonization and activation. PLC is dispersed in a chitosan / acetic acid aqueous solution, coated onto the surface of MOF@WA, and dried to obtain a PLC@MOF@WA wood-based evaporator. This evaporator exhibits high photothermal conversion efficiency and evaporation rate, and can be used for solar-driven water evaporation at a solar irradiance of 1 kW / m². 2 Its evaporation rate reaches 2.5594 kg·m³. ‑2 ·h ‑1 It can effectively purify seawater at a low cost.
