Abstract

The invention discloses a preparation method of a dust removal filter material with high wear resistance, and relates to the technical field of dust removal, and the preparation method specifically comprises the following steps: (1) preparation of a composite impregnation liquid: compounding water-based phenolic resin, a penetrant, a dispersant, a powder material and pure water according to a certain mass ratio, and uniformly stirring to prepare the composite impregnation liquid; (2) preparation of a needled felt: processing the heat-resistant fibers to prepare the needled felt; and (3) filter material treatment: uniformly dispersing the composite impregnation liquid prepared in the step (1) into the needled felt in the step (2) through an impregnation-pressing process, and preparing the high-wear-resistance dust removal filter material with high wear resistance through high-temperature heat setting. And (4) performance testing: testing the wear resistance of the high-wear-resistance dust removal filter material prepared in the step (3). The process is simple, industrialization is facilitated, the water-soluble steeping liquor is adopted, no organic solvent exists, the environmental protection property is high, the filter material abrasion resistance of the gradient filter material can be remarkably improved, and the gradient filter material is not prone to being damaged.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a preparation method of a high wear resistance dust removal filter material. Background technique [0002] The filter bag is the core component of the dust removal stage in the current flue gas treatment field, so the performance of the filter bag is related to ultra-low emissions. The current filter materials mainly include needle-punched felt filter materials, film-coated filter materials, spunlace felt filter materials, and sea-island fibers. However, under the situation of increasingly stringent emission standards and increasingly complex working conditions, functionalized filter materials have attracted more and more attention from the industry. [0003] However, due to the shortcomings of the gradient filter material such as its small thickness and poor wear resistance, in the actual working conditions, especially the working conditions of high dust concentration, high...
