Novel geometrically symmetrical absorption tower flue gas outlet device

Abstract

The invention provides a novel geometrically symmetrical absorption tower flue gas outlet device. The absorption tower flue gas outlet device comprises a trapezoidal corner cylinder, a disc and a circular absorption tower wall plate, and the disc is fixedly mounted between the trapezoidal corner cylinder and the circular absorption tower wall plate; a circular short connection cylinder is fixedlymounted on the outer surface of one side of the trapezoidal corner cylinder; a circular flange is fixedly connected to the outer surface of one side of the circular short connection cylinder; and an overhauling opening is formed in the outer surface of the upper end of the trapezoidal corner cylinder, a triangular overhauling table is movably connected to the interior of the overhauling opening, the triangular overhauling table is composed of a first limiting plate, a second limiting plate and a third limiting plate, and the second limiting plate is movably installed between the first limitingplate and the third limiting plate. According to the device, flue gas can uniformly flow, the flue gas exhaust speed is increased, rainwater infiltration is prevented, the detection space is increased, maintenance is convenient, in addition, rainwater corrosion can be reduced, and rainwater recycling is facilitated.

Description

technical field [0001] The invention relates to the technical field of flue gas outlet devices for absorption towers, in particular to a novel geometrically symmetrical flue gas outlet device for absorption towers. Background technique [0002] When choosing flue gas desulfurization equipment for thermal power plants at home and abroad, the limestone and gypsum forced oxidation system has become the preferred wet flue gas desulfurization process. The key equipment is the desulfurization absorption tower. There are many types of flue gas outlet devices for the absorption tower and are widely used. . [0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art that have not been solved: 1. When the general absorption tower is in use, the flue gas floats inside it, and the tower is airtight, so the flue gas cannot flow evenly, slowing down Flue gas discharge speed; 2. Regular maintenance will be...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art that have not been solved: 1. When the general absorption tower is in use, the flue gas floats inside it, and the tower is airtight, so the flue gas cannot flow evenly, slowing down Flue gas discharge speed; 2. Regular maintenance will be carried out when the absorption tower is in use. The general inspection port will directly cover a top cover. After long-term rainwater corrosion and infiltration, the flat top cover will easily cause rainwater to enter the tower. The mouth is generally located on the top of the tower, the space of the detection table is limited, and it is inconvenient to carry tools, so it is inconvenient to maintain; 3. There are gaps in the connection between the absorption towers. Rainwater spills and accumulates on the table, which is easy to cause corrosion of the device and waste of water resources.
