Asymmetric cone spine array oil mist collecting device and preparation and collecting method thereof

Abstract

The invention belongs to the technical field of oil mist collecting devices, and particularly relates to an asymmetric conical thorn array oil mist collecting device which comprises a base and a plurality of asymmetric conical thorns arranged on the base. The asymmetric conical spines are arranged on the substrate in an array manner, and two adjacent rows of asymmetric conical spines are arranged in a staggered manner; the asymmetric cone thorn comprises an upper half cone and a lower half cone which are integrally connected, the upper half cone is a semi-elliptical cone, the lower half cone is a semi-cone, and the semi-elliptical cone and the semi-cone converge to form a cone tip; the curvatures of the semielliptical cones are sequentially reduced from the cone bottom to the cone tip, and the curvature is 0 when the semielliptical cones reach the cone tip end; the substrate is oleophobic, and the asymmetric conical spines are oleophilic. The invention further discloses a preparation method and a collection method of the non-aligned cone spines, the shape of the non-aligned cone spines is adjusted, so that the Laplace pressure difference and the gravity direction are the same, the transportation effect of the upper half cone is enhanced, the overall liquid collection and transportation efficiency of the cone spines is improved, and the self-cleaning performance of the whole cone spines is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of oil mist collecting devices, and in particular relates to an oil mist collecting device of an asymmetric cone-spine array and a preparation and collecting method thereof. Background technique

[0002] With the development of productivity, environmental protection has been paid more and more attention. According to research statistics, the particle size of oil fume produced by the catering industry is concentrated at 2.5 microns, and the micron-level oil mist can be inhaled by the human body, which has an impact on human health. Because the particle size of the oil mist is too small, it cannot rely on its own gravity to settle.

[0003] The current oil mist collection technology is mainly divided into mechanical treatment method, chemical treatment method and catalytic purification method. In the mechanical treatment method, inertial separation has low efficiency for micron-level oil fume collection, and e...
