The invention relates to an exhaust gas dedusting, denitration and desulfuration method for a thermal power plant. According to the invention, after being dedusted firstly by a bag-type dust collector, high-temperature raw exhaust gas is introduced in an SCR (selective catalytic reduction) reactor for performing SCR for realizing denitration, and then, the exhaust gas subjected to denitration passes through an air preheater and a heat exchanger in sequence to be cooled to 90-100 DEG C, and then is subjected to wet desulfuration in a desulfurizer; and the exhaust gas subjected to desulfuration and discharged from the desulfurizer is heated to 100-105 DEG C by the heat exchanger and then enters a chimney to be discharged. In the bag-type dust collector, filter cloth in a filter bag has base cloth which is PBO (Poly-p-phenylenebenzobisthiazole) fiber woven cloth and has two surface layers referring to composite fibrofelts formed by cross-laying of PBO fiber nets and basalt fiber nets, the base cloth is sandwiched between the two surface layers and sewed up into a whole body, the whole body is subjected to hot rolling, singeing and heat shaping, Teflon dipping and drying to finally form high-temperature resistant filter cloth. By the adoption of the high-temperature resistant filter bag, the raw exhaust gas can be dedusted firstly at a high temperature and then is subjected to denitration, therefore, ash fouling of subsequent equipment and damages to a catalyst can be reduced, and the effects of low catalyst consumption and high denitration efficiency can be achieved; and since the catalytic reaction does not need additional heat, the effects of energy saving and emission reduction are achieved.
