Embodiment

[0029] see figure 2 and image 3 , present embodiment relates to dedusting method, comprises the following steps:

[0030] Step 1. The liquid pump 1 draws the spinning solution from the recovery tank 2 and supplies it to the spinning needle 3; the spinning solution is a PCL or PVA solution, and the mass fraction of the solution is 5%-20%.

[0031] Step 2. Nanofibers are formed through the electrospinning process, and the nanofibers are arranged on the flow circuit of the gas to be filtered; the nanofibers absorb the dust in the gas; a 2-30KV high-voltage electrostatic field is attached to the spinning needle 3, and the spinning needle 3Through electric field traction and thinning, between the spinning needle 3 and the collecting plate 4, spray to form electrospun nanofibers; form nanofibers.

[0032] Step 3, heat the nanofibers with dust to a molten state, and flow into the recovery tank 2, where the dust is separated and precipitated in the recovery tank 2; The nanofiber...

Abstract

The invention discloses a dedusting method based on an electric spinning technique. The dedusting method comprises the following steps of S1, enabling a liquid pump to suck a spinning solution from arecycling tank and supply to a spinning needle head; S2, forming a nanometer fiber by an electrostatic spinning technique, and arranging the nanometer fiber on a flowing loop of the to-be-filtered gas; enabling the nanometer fiber to suck the dust in the air; S3, heating the dust-containing nanometer fiber to the melting state, enabling the dust-containing nanometer fiber to flow into the recycling tank, and separating and settling the dust in the recycling tank; S4, repeating the steps until the dust in the to-be-filtered gas is filtered out. The invention also discloses a dedusting device based on the electric spinning technique. The dedusting method has the advantages that the whole dedusting process is simple, convenient and efficient, and the gas can be cyclically dedusted; the use cost can be greatly reduced, and the green and environment-friendly effects are realized; the problems of long-time, fixed-time and frequent replacing of filtering membranes or filtering medium, troublesome and inconvenience in use, and higher cost in the existing dedusting method are solved.

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to a dust removal method and a dust removal device, in particular to a dust removal method and a dust removal device based on electrospinning technology. Background technique [0002] The filtration efficiency of the fiber filter material will increase with the decrease of the fiber diameter, therefore, reducing the fiber diameter becomes an effective method to improve the filtration performance of the fiber filter material. The preparation of nanofiber materials by electrospinning technology is one of the most important academic and technical activities in the field of material science and technology in the world in the past ten years. Electrospinning has become one of the main ways to effectively prepare nanofiber materials due to its advantages of simple manufacturing equipment, low spinning cost, wide variety of spinnable materials, and controllable process. In addition ...
