Example Embodiment

[0024] Example one
[0025] Such as figure 1 As shown, the improved desulfurization equipment is composed of a wet desulfurization device 1, a gas pipe 2, a connecting pipe 3, a connecting plate 4, and the like. Among them, the wet desulfurization device 1 is an existing product, such as a wet desulfurization device disclosed by the Chinese Patent Library [application number: 201510796580.4; publication number: CN105268304A], and the bottom of the wet desulfurization device 1 has a flue gas inlet .
[0026] Specifically, there are two wet desulfurization devices 1 arranged side by side. Each wet desulfurization device 1 is provided with an air pipe 2 at the bottom, each air pipe 2 is L-shaped, and each air pipe 2 includes a vertically arranged air outlet 2a and a horizontally arranged air inlet 2b. Among them, the two air outlets 2a are respectively connected with two flue gas inlets. In this embodiment, the upper end of the gas outlet portion 2a is inserted into the flue gas inlet, the outer side wall of the gas outlet portion 2a and the inner side wall of the flue gas inlet tightly abut to form a seal, and the gas outlet portion 2a is connected to the wet desulfurization device 1 by welding. Phase fixed.
[0027] The connecting pipe 3 has a straight tube shape and is vertically arranged between the two air inlets 2b. The upper end of the connecting pipe 3 is closed and the lower end is open. The two air pipes 2 are fixed to the connecting pipe 3, and each air inlet 2 b is connected to the connecting pipe 3. Specifically, the side wall of the connecting pipe 3 has a connecting portion 3a protruding in a cylindrical shape, the inner cavity of the connecting portion 3a is communicated with the inner cavity of the connecting pipe 3, and the connecting portion 3a and the connecting pipe 3 are of an integrated structure. Such as figure 1 As shown, there are two connecting parts 3a and their positions are directly opposite to the two air inlet parts 2b. The two air inlet parts 2b are respectively inserted and fixed in the two connecting parts 3a, and between the air inlet part 2b and the connecting part 3a It is provided with a sealing structure for connecting and sealing the two. In this embodiment, as figure 1 with figure 2 As shown, the air inlet portion 2b is fixed to the connecting portion 3a by welding; the sealing structure includes an annular sealing groove provided on the outer side wall of the air inlet portion 2b and an O-shaped sealing ring 2 5 arranged in the annular sealing groove, and The outer peripheral surface of the O-ring two 5 abuts against the inner side wall of the connecting part 3a, so that a reliable seal is formed between the connecting part 3a and the air inlet 2b to avoid leakage of exhaust gas during transportation, thereby further improving the equipment Work stability.
[0028] To further illustrate, the outer side wall of the air inlet portion 2b has a tapered guide surface 2c, and the guide surface 2c extends to the end surface of the air inlet portion 2b to facilitate the installation of the connecting pipe 3 and the air pipe 2.
[0029] Such as figure 1 with image 3 As shown, the lower end of the connecting pipe 3 is screwed with a connecting plate 4, the connecting plate 4 has four through holes 4 a extending along the axial direction of the connecting pipe 3, and the four through holes 4 a are evenly distributed along the circumferential direction of the connecting pipe 3. The side wall of the connecting plate 4 is provided with an annular groove, and the 0-shaped sealing ring 6 is arranged in the annular groove, and the outer peripheral surface of the 0-shaped sealing ring 6 abuts against the inner side wall of the connecting pipe 3 so that the connecting pipe 3 A reliable seal is formed with the connecting plate 4.
[0030] During installation, the four boilers are respectively connected to the four through holes 4a through pipes; when in use, the exhaust gas generated by the four boilers is collected in the connecting pipe 3 through the pipes, and then divided into the two wet desulfurization devices 1 through the two gas pipes 2. Purify.

Example Embodiment

[0031] Example two
[0032] The structure and principle of the second embodiment are basically the same as those of the first embodiment. The difference lies in: the outer side wall of the air inlet portion 2b has a convex annular shoulder, and the annular shoulder is coaxial with the inlet portion 2b and has an annular shape. The shoulder and the connecting portion 3a abut against each other. The sealing structure includes an annular groove provided on the end surface of the annular shoulder and an annular sealing gasket arranged in the annular groove. The two end surfaces of the annular gasket respectively abut against the bottom wall of the annular groove and the end surface of the connecting portion 3a.
