Glass fiber composite tube

Abstract

The invention relates to the field of industrial flue gas treatment equipment, in particular to a glass fiber composite tube. The glass fiber composite tube is obtained by mixing a glass fiber material, a catalyst and a binder and then pressing, drying and forming, wherein the catalyst accounts for 3-30% of the total mass of all the materials. The glass fiber material is one or more of glass fiberspun yarns, glass fiber rough yarns and a chopped strand mat; the catalyst is a denitration catalyst or a dioxin removing catalyst; and the binder is a high-temperature-resistant inorganic binder. The glass fiber composite tube is used in the field of flue gas treatment, a large number of tiny gaps are formed in the tube wall, gas out of the tube can enter the inside of the tube through the gaps,and meanwhile, dust with the size greater than 2.5-10 mu m is stopped from penetrating the tube wall; the highest tolerable temperature of the glass fiber composite tube is 950 DEG C, the glass fibercomposite tube is suitable for treating high-temperature flue gas in various boilers, kilns, incinerators, ship tail gas and the like, and the problem that an existing cloth bag for cloth bag dust removal only resists 220 DEG C is solved effectively; and the glass fiber composite tube can desorb oxynitride in flue gas and remove dioxin, and meanwhile, desulfuration is assisted.

Description

technical field [0001] The invention relates to the field of industrial flue gas treatment equipment, in particular to a glass fiber composite pipe. Background technique [0002] With the development of industry, environmental pollution is becoming more and more serious, especially the combustion of various industrial kilns and boilers is an important source of pollution that transports pollutants to the atmosphere. General fuels include coal, gas and natural gas. The main component of coal is carbon and contains hydrogen, oxygen, nitrogen, sulfur and metal compounds. In addition to producing a lot of smoke and dust during combustion, carbon monoxide, carbon dioxide, sulfur dioxide, and Nitrogen oxides, organic compounds, smoke and other substances. Coal gas is produced from coal, and the products of combustion are similar to coal. Natural gas is relatively clean energy, but during its high-temperature combustion, oxygen, sulfur in the heated raw materials, and nitrogen in...
