Description

Technical Field

[0001] The utility model relates to the technical field of absorption towers, in particular to an absorption tower outlet flue structure which is convenient to install. Background Art

[0002] Coal-fired flue gas is a mixture of gas and smoke, and is the main cause of atmospheric pollution. The composition of flue gas is very complex and needs to be treated to meet the standards before it can be discharged. Desulfurization absorption towers are often used in flue gas treatment, and flue ducts are an important part of flue gas transportation. After desulfurization, the clean flue duct is generally installed above the absorption tower for smoke exhaust.

[0003] When installing the existing outlet flue of the absorption tower with the absorption tower, the flue is large in size, heavy in weight and installed at a high height, so the installation requires the assistance of a crane. However, when the crane lifts the flue and installs it on the top of the absorption tower, the crane cannot accurately connect one end of the flue with the top of the absorption tower during installation, which requires multiple workers to push and rotate the flue for alignment welding. In addition, local deformation after welding causes the positioning deviation of the outlet flue to need further correction. The whole process is cumbersome and labor-intensive, and greatly reduces the installation efficiency of the flue.

[0004] Therefore, we propose an absorption tower outlet flue structure that is easy to install. Utility Model Content

[0033] A second annular groove 84 is formed on the inner surface of the second annular connecting block 82 , and second arcuate sliders 85 distributed in an annular array are slidably connected to the inner wall of the second annular groove 84 . The second arcuate sliders 85 play a role of guiding sliding in the second annular groove 84 .

[0034] The inner surface of the second arc-shaped slider 85 is fixedly connected to the outer surface of the arc-shaped moving block 8, and a smoke exhaust pipe 86 is movably inserted into the inner wall of the connecting pipe 2. A third annular connecting block 87 is fixedly sleeved on the outer surface of the smoke exhaust pipe 86. The third annular connecting block 87 is used to cooperate with the fixed limit of the smoke exhaust pipe 86.

[0035] The lower surface of the third annular connecting block 87 contacts the upper surface of the first annular connecting block 4. A first through hole 88 is opened on the upper surface of the third annular connecting block 87. A first bolt 89 is movably sleeved on the inner wall of the first through hole 88. A sealing gasket is provided on the lower surface of the third annular connecting block 87 for cooperating with the connection sealing function with the first annular connecting block 4.

[0036] The outer surface of one end of the first bolt 89 is threadedly connected to the inner wall of the first threaded hole 81, and the lower surface of the arc-shaped moving block 8 is fixedly connected with a positioning block 810.

[0038] Through the convenient installation device, the conical inclined surface of the conical guide tube 3 is used to guide one end of the smoke exhaust pipe 86 during installation, so that it is easy to insert it into the connecting tube 2 for preliminary positioning, thereby avoiding the need for manual repeated rotation and pushing of the flue to make the two sets of installation holes overlap and connect, and through the rotation of the arc-shaped moving block 8, the smoke exhaust pipe 86 can be connected and fixed without manual rotation, which is convenient to operate, greatly reduces manual labor, and improves the installation efficiency.

[0039] The utility model workflow:

[0040] Step 1: During installation, the smoke exhaust pipe 86 is lifted by a crane, and then one end of the smoke exhaust pipe 86 is inserted into the connecting pipe 2 through the tapered guide pipe 3. The inner inclined surface of the tapered guide pipe 3 guides one end of the smoke exhaust pipe 86 to move, so that the one end of the smoke exhaust pipe 86 is inserted into the connecting pipe 2 for preliminary positioning. When the smoke exhaust pipe 86 is inserted into the connecting pipe 2, the third annular connecting block 87 contacts the first annular connecting block 4, and the crane can be stopped.

[0041] Step 2: The arc moving block 8 is driven to move by the positioning block 810. The arc moving block 8 is stably moved by the cooperation of the first arc sliding block 7 and the second arc sliding block 85. The threaded hole of the arc moving block 8 is rotated until it overlaps and connects with the first through hole 88 of the third connecting block and then stops moving. At this time, one end of the first bolt 89 is passed through the first through hole 88 and screwed into the first threaded hole 81, so that the exhaust pipe 86 is stably connected and fixed to the connecting pipe 2.

[0042] Step three, if the smoke exhaust angle of the smoke exhaust pipe 86 needs to be rotated, the smoke exhaust pipe 86 can be driven by a crane and a pull rope to be positioned and rotated. The positioning rotation of the smoke exhaust pipe 86 is driven by the third connecting block and the arc-shaped moving block 8 to drive the positioning block 810 to rotate. When the smoke exhaust pipe 86 is adjusted to a suitable smoke exhaust angle, the second bolt 812 is passed through the second through hole 811 and screwed into the second threaded hole 83, thereby limiting the rotation of the smoke exhaust pipe 86. In this way, the fixed installation of the smoke exhaust pipe 86 is completed.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
