Method for preparing composite plate by recycling bag type dust remover waste filter bags

Abstract

The invention discloses a method for preparing a composite plate by recycling bag type dust remover waste filter bags; the waste filter bags are successively subjected to crushing, cleaning, drying, shredding, mixing of glass fibers and the crushed opened material, acupuncture composite, high-temperature pressing, cooling and design finalizing, and finished product composite plate obtaining. Compared with the prior art, produced building templates and wall partition plates have no high requirements on a cleaning process and can be covered with cement and the like on the outside during the using process, so that no requirement exists for building remaining cement or lime compositions; with recycling of the waste filter bag resources, secondary pollution caused by landfilling, incineration and other processing methods is effectively solved, so as to contribute to resource re-utilization, energy saving, emission reduction and other works; in the high-temperature pressurization process, thermoplastic fibers are dissolved to play a bonding effect, so that a glue and other binders are replaced, and produced boards do not contain formaldehyde, the glue and other harmful substances and belong to green environmental-protection building materials.

Description

technical field [0001] The invention relates to a technology for recycling thermoplastic fibers in waste filter bags of dust collectors, in particular to a method for recycling waste filter bags of bag type dust collectors to make composite boards. Background technique [0002] Bag filter is currently the most widely used and most mature dust removal equipment in the world; due to its high dust removal efficiency, simple structure, strong adaptability, stable work, and recyclable dry materials, it has been widely used in various industries. With the wide application of bag filters, most of these filter bags are made of synthetic chemical fiber raw materials, which have poor biodegradability and are difficult to be degraded in nature; and because there is no effective disposal method at present, random stacking has become a new product. source of pollution. Therefore, how to effectively dispose of damaged waste filter bags has become an urgent problem to be solved at present...

AI Technical Summary

Problems solved by technology

[0004] Landfilling is the simplest and most practical way to solve waste filter bags, but landfilling will pollute soil and groundwater

[0005] Incineration, gas pollution during the incineration process

[0006] Re-drawing is the best way to solve the waste filter bag, but it is difficult to achieve in actual operation

In the process of returning to the furnace, the chemical composition of the fiber changes, and the cleaning is not thorough enough, which leads to the high cost of reuse
