1. An installation method of a refractory fiber integral module, comprising:
carrying out construction pretreatment, and welding anchoring parts to a furnace wall after the pretreatment is completed;
laying a tiled layer along the furnace wall, wherein the tiled layer comprises refractory fiber blankets and nano plates;
fixing refractory fiber integral modules on a hot surface of the tiled layer by the anchoring parts to form a refractory fiber prefabricated layer, and filling reserved gaps between the refractory fiber integral modules with compensation strips; and
checking the refractory fiber prefabricated layer, and repairing gaps whose width is greater than a preset width,
the step of laying the tiled layer along the furnace wall comprises:
performing a water spray test on the furnace wall to determine whether a weld seam is leaking, and if the weld seam leaks, performing repair welding;
laying a plurality of refractory fiber blankets along the furnace wall to form a first tiled layer covering an inner side wall of the furnace wall, wherein each of the plurality of refractory fiber blankets within the first tiled layer is first tensed from one end to another end, then passed through a corresponding anchoring part, then fixed with a snapping piece, and then flattened;
laying a plurality of nano plates along the first tiled layer to form a second tiled layer covering the first tiled layer, wherein each of the plurality of nano plates within the second tiled layer is first tiled from one end to another end, then passed through a corresponding anchoring part, then fixed with a snapping piece, and then flattened; and
laying a plurality of refractory fiber blankets along the second tiled layer to form a third tiled layer covering the second tiled layer, wherein each of the plurality of refractory fiber blankets within the third tiled layer is first tensed from one end to another end, then passed through a corresponding anchoring part, then fixed with a snapping piece, and then flattened;
wherein the tiled layer comprises at least two layers of the refractory fiber blankets and at least one layer of nano plates, seams of the two layers of refractory fiber blankets are staggered with each other, and a seam spacing is larger than a second preset value.
