Embodiment approach

[0046] In order to better demonstrate the implementation process of the blast furnace flue gas multi-stage guide purification device, the present embodiment now proposes an implementation method of the blast furnace flue gas multi-stage guide purification device, including the following steps:

[0047] Step 1: Install the purification device in the blast furnace flue, the primary barrier 1 and the secondary barrier 2 are respectively movably connected to the blast furnace flue through the short shaft 13, and the driving motor 42 works to drive the fan main body 41 to rotate, which generates in the blast furnace flue. Negative pressure, attracting flue gas to enter from the end of the blast furnace flue near the primary barrier plate 1;

[0048] Step 2: The worm wheel 431 drives the worm 511 to rotate, thereby controlling the long rotating shaft 51 to work, and through the action of the rotating rod 53 and connecting the tie rod 54, the secondary barrier plate 2 rotates around t...

Abstract

The invention discloses a blast furnace flue gas multi-stage guide purification device and an implementation method, and relates to the technical field of flue purification. Comprising a first-stage baffle, a second-stage baffle, an overturning baffle assembly and an air inducing assembly, the overturning baffle assembly is arranged between the first-stage baffle and the second-stage baffle, a supporting frame is arranged on the side, away from the first-stage baffle, of the second-stage baffle, and the supporting frame is movably connected with the air inducing assembly. According to the blast furnace flue gas multi-stage guiding purification device and the implementation method, negative pressure control over the blast furnace flue is achieved through the air inducing assembly, flue gas is sucked into the blast furnace flue, triple purification is achieved through the first-stage blocking plate, the overturning blocking assembly and the second-stage blocking plate, the impurity removal efficiency is improved, impurities in the flue gas are reduced, and the service life of the flue gas is prolonged. The problems that in the prior art, a flue is too long and not easy to install, a spraying mode is directly adopted for purification, much sewage is generated, and the later sewage treatment capacity is large are solved.

Description

technical field [0001] The invention relates to the technical field of flue purification, in particular to a multi-stage guide purification device for blast furnace flue gas and an implementation method. Background technique [0002] The flue gas purification device mainly includes a bag dust removal device and a spray-type purification device; the purification principle of the spray-type purification device is: when the flue gas passes through the fog-like space, due to the collision, interception and condensation between dust particles and droplets As a result, the dust particles fall down with the droplets. The disadvantage of the spray-type purification device in the prior art is that the residence time of the flue gas in the device is too short, resulting in insufficient purification of the flue gas. [0003] Chinese patent CN215352653U discloses a flue gas purification device, including a flue and a spray device; the flue is a "snake"-shaped pipe, and the flue is plac...
