Embodiment Construction

[0010] A gas inlet pipe sealing structure for Ouyeel furnace bag dust removal, such as figure 1 , figure 2 As shown, it mainly includes: circular plate 1, cylindrical tube 2, circular plate 3, cylindrical tube 4, circular plate 5, cylindrical tube 6, circular plate 7, cylindrical tube 8, flower partition 9, packing and pressing Cover seal 10, raw gas inlet pipe 11, reinforcement plate 12; cylindrical pipe 2 is cylindrical in shape, and its upper part is assembled and welded with circular plate 1 to form a triangular weld. The thickness of the weld seam is not less than the wall thickness of the cylindrical pipe. Ring plate 3, its inner diameter is 80 mm larger than the outer diameter of the raw gas pipeline, its outer circumference is welded to the lower part of the cylindrical tube 2, and its inner circumference is welded to the upper part of the cylindrical tube 2, and the ring plate 3, cylindrical tube 4, and ring plate are sequentially produced 5. Cylindrical tube 6, cir...

Abstract

The invention discloses a bag dedusting coal gas guide-in pipe sealing structure of an Ouye furnace. The sealing structure mainly comprises an annular plate (1), a cylindrical pipe (2), an annular plate (3), a cylindrical pipe (4), an annular plate (5), an cylindrical pipe (6), an annular plate (7), an cylindrical pipe (8), a pattern partition board (9), a padding and gland seal (10), a crude gasguide-in pipe (11) and reinforcing rib plates (12). The cylindrical pipe (2) is cylindrical. The upper portion of the cylindrical pipe (2) is assembled and welded to the annular plate (1). The annularplate (3) is manufactured in sequence. The inner diameter of the annular plate (3) is 80 mm greater than the outer diameter of a crude gas pipe. The outer circumference of the annular plate (3) is welded and connected to the lower portion of the cylindrical pipe (2). The inner circumference of the annular plate (3) is welded and connected to the upper portion of the cylindrical pipe (2). The annular plate (3), the cylindrical pipe (4), the annular plate (5) and the cylindrical pipe (6) are manufactured in sequence. The annular plate (1), the cylindrical pipe (2), the annular plate (3), the cylindrical pipe (4), the annular plate (5) and the cylindrical pipe (6) constitute a pi-type compensator. The annular plate (7) and the cylindrical pipe (8) constitute an L-type compensator.

Description

technical field [0001] The invention relates to a sealing structure of a gas introduction pipe for bag dust removal of Ouyeel furnace. Background technique [0002] In order to realize the function of energy saving and environmental protection, Ouyeel Furnace transformed the top gas packing scrubber and adjustable venturi scrubber into a gravity dust removal and dry dust removal system. The dry dedusting gas purification process is used to replace the original COREX shaft furnace gas wet dedusting process. The normal operating temperature range of the shaft furnace top of Ouyeel furnace is 150-250°C, so that the temperature of the raw gas is higher than that of the blast furnace top. The raw gas inlet pipe in the middle of the dust bag box enters from top to bottom. Due to the need to overcome the displacement of the pipeline after the temperature change, the connection between the raw gas inlet pipe and the flower partition installed with the cloth bag cannot be welded and...
