Method and system for producing glass fiber products by using liquid deslagging boiler

Abstract

The invention provides a method and a system for producing glass fiber products by using a liquid deslagging boiler, and relates to the field of waste gas and solid waste treatment. According to the system and the method for producing the glass fiber products through the liquid slagging boiler, the total discharge amount of solid waste of a power plant can be reduced, waste heat of slag liquid can be effectively utilized, meanwhile, steam, pressurized air, electric energy, circulating water and other process products generated by the boiler of the power plant are efficiently utilized, and the production cost is reduced. The solid wastes of the power plant are converted into industrial products by utilizing equipment of the boiler. Compared with a traditional method, the energy utilization efficiency is improved, solid waste emission of a power plant is reduced, pollutant emission is reduced, and economic benefits and social benefits of the power plant are increased.

Description

technical field [0001] The invention relates to the field of waste gas and solid waste treatment, in particular to a method and system for producing glass fiber products using a liquid slag discharge boiler. Background technique [0002] Glass fiber products such as rock wool are high energy consumption and high pollution products. The main production process is to heat the raw materials to a molten state and then use processing equipment to process the melt into glass fiber products such as rock wool. Therefore, a large amount of energy is consumed in the entire processing process. Energy melts the raw materials at high temperature, and the high-temperature flue gas generated during the production process needs to be treated with environmental protection such as dust removal and desulfurization. At present, domestic rock wool manufacturing furnaces use a large number of coke furnaces. This furnace has the advantages of simple process and convenient raw materials, but has th...

AI Technical Summary

Problems solved by technology

At present, domestic rock wool manufacturing furnaces use a large number of coke furnaces. This furnace has the advantages of simple process and convenient raw materials, but it has the disadvantage of high energy consumption. At the same time, it will also generate high temperatures containing a large amount of pollutants such as nitrogen oxides, sulfur dioxide, and dust. Flue gas seriously affects environmental protection. Therefore, in some areas with stricter energy and environmental protection policies, the rock wool manufacturing industry has been greatly restricted and even some factories have been shut down for processing.
