Packed tower for removing sulfur dioxide

Abstract

The invention discloses a packed tower for removing sulfur dioxide, the packed tower comprises a tower body, a packing frame plate and a packing layer, the tower body of an integrated structure is modified into a separated structure form of an upper tower body and a lower tower body, and a positioning insertion rod is inserted into each positioning insertion groove in a matching manner in a drawable manner; the front end plate body and the rear end plate body of the stress pressing plate are correspondingly arranged on the guide sliding columns in a penetrating mode in a sliding mode, each guide sliding column is correspondingly sleeved with a reset spring, a second rotating shaft is correspondingly and fixedly sleeved with the force application cam, and a second driven bevel gear is coaxially and fixedly installed at the front end of the second rotating shaft. The first driven bevel gear on the left side and the first driven bevel gear on the right side are in transmission fit with the first driving bevel gear in a bevel gear meshing mode. According to the invention, the purpose of replacing or taking out the failed filler part for cleaning is realized, and the high efficiency of the filler part for purifying sulfur dioxide is ensured.

Description

technical field [0001] The invention relates to the related technical field of sulfur dioxide purification equipment, in particular to a packed tower for removing sulfur dioxide. Background technique [0002] The flue gas desulfurization packed tower is a device for desulfurization of industrial waste gas. [0003] see figure 1 , figure 1 Indicates the structural schematic diagram of the flue gas desulfurization packed tower in the prior art, an invention patent with publication number CN203935774U and application number CN201420396659.9 published on China Patent Online. [0004] In this patent, its specific structure includes a tower body 1, a packing frame plate 2 and a packing layer 3. The tower body 1 is set as an integrated structure, and the packing frame plate 2 is installed on the inner wall of the tower body 1 in a fixed and non-detachable form. Other remaining structures are described in detail in this patent, and will not be repeated here. [0005] Although th...

Problems solved by technology

[0005] Although the packed tower of the integrated structure of this prior art can remove sulfur dioxide, there is a serious defect, that is, under the long-term purification state, the impurity particles produced are easy to destroy the packing layer 3, resulting in the packing layer 3. The purification effect fails, and the purification of sulfur dioxide cannot be continued. The packing layer 3 needs to be directly replaced or cleaned after being taken out, and the packing frame plate 2 is installed on the inner wall of the tower body 1 in a fixed and non-detachable form, which leads to the fact that the existing technology is fundamentally It is impossible to take out the packing layer 3, and the entire packing layer 3 is only for "one-time" use, which leads to great work restrictions on the entire packed tower. We have developed a method that can remove the packing frame plate 2 and packing layer 3 for replacement or cleaning. device is particularly important

[0006] For this reason, the present invention provides a novel packing tower for removing sulfur dioxide to solve the problem that cannot be replaced or cleaned in the prior art, and the improved detailed structure is now described
