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

Abstract

The invention belongs to the technical field of oil mist collecting devices, and relates to a composite cone thorn array oil mist collecting device which comprises a plurality of layers of collecting units, and each layer of collecting unit comprises a base plate and a plurality of composite cone thorns transversely arranged on the base plate; the composite conical thorns are distributed on the substrate in a staggered array mode, a plurality of through holes are formed in the substrate, and the through holes are formed between every two adjacent composite conical thorns; the composite cone thorn comprises an upper half cone and a lower half cone which are integrally connected, the upper half cone is a triangular cone, the lower half cone is a semi-cone, one side face of the triangular cone and the plane of the semi-cone are coplanar, and the triangular cone and the semi-cone are converged to form a tip end. An oleophilic and oleophobic interface is prefabricated on the composite cone thorn, the part between the tip end and the oleophilic and oleophobic interface is an oleophylic section, and the part between the oleophilic and oleophobic interface and the root of the composite cone thorn is an oleophobic section. By changing the dropping position of oil drops, formation of a substrate liquid film is effectively prevented, and the surface has a self-refreshing characteristic, so that the oil mist capturing and collecting device is particularly suitable for capturing and collecting oil mist with relatively high viscosity.

Description

technical field [0001] The invention belongs to the technical field of oil mist collection devices, and in particular relates to an oil mist collection device of a composite cone-spine array and a preparation method and collection method thereof. Background technique [0002] The use of lubricating oil and cutting oil in industry produces a large amount of oil mist. Among them, the micron oil mist accounts for a large proportion, and the particle size of the micron oil mist is small, which can be inhaled by the human body and cause human diseases. If the generated oil mist cannot be collected and separated from the air in time and discharged into the atmosphere, it will cause great harm to the atmosphere. pollution, and even cause serious environmental pollution such as smog. However, oil mist particles with a particle size of less than 100 microns cannot rely on their own gravity to settle, and the size of the particle size makes it difficult to collect them. In addition,...
