Problems solved by technology

At present, the dust-removing bag materials commonly used in the market have poor high-temperature resistance and are not flame-retardant, so they cannot meet the more stringent conditions of use. Those skilled in the art are waiting to develop a new type of flame-retardant and high-temperature-resistant dust-removing bag material.

Abstract

The invention discloses a flame-resistant and high temperature-resistant dust collecting bag material, relating to the technical field of dust removal. The flame-resistant and high temperature-resistant dust collecting bag material is prepared from the following raw materials in parts by weight: poly(phenylene sulfide sulfone), soluble polytetrafluoroethylene, modified polyester, carbon nanotubes,chlorinated polyether, polyacrylonitrile carbon fibers, silicon carbide staple fibers, calcium sulfate whiskers, ionically modified clay, a flame retardant, a coupling agent, an antistatic agent andan anti-ageing agent. Due to scientific proportioning and mutually synergic effect of the components, the heat resistance, acid resistance, static electricity resistance and deformation prevention ofa dust collecting bag are improved, thus the dust collecting bag is applicable to complex environments and wide in application range. Meanwhile, the joint effect of the silicon carbide and ionically modified clay improves the surface binding performance of the soluble polytetrafluoroethylene and the adsorption effect. Due to the added calcium sulfate whiskers, the adsorption effect of the dust collecting bag is further increased and the dust collecting capability of the dust collecting bag is high in popularization value.

Description

technical field [0001] The invention belongs to the technical field of dust removal, and in particular relates to a flame-retardant and high-temperature-resistant dust-removing cloth bag material. Background technique [0002] The flue gas dedusting device of a coal-fired power plant is one of the important production equipment of the power plant. Therefore, when designing the dust bag material (filter material), it must be ensured that it can operate reliably for a long time; and the operation of the boiler and its auxiliary equipment must be fully considered. conditions, fuel and dust characteristics, and possible problems in operation. In the case of constant fuel, the characteristics of the dust-laden flue gas mainly depend on the combustion conditions of the boiler, and are also affected by the material of the dust bag material. The change of boiler load, the dust concentration of the flue gas, the size of the pulverized coal particles directly affect the flue gas volu...
