Description

Technical Field

[0001] The utility model relates to the technical field of demisters, in particular to a demister suitable for a desulfurization absorption tower. Background Art

[0002] The demister works on the inertia and gravity of the droplets in the flue gas. When the flue gas with droplets passes through the demister channel at a certain speed, the flue gas is forced to change direction continuously during the movement due to the curved structure of the flue itself, so that the flue gas flow can achieve gas-liquid separation under the action of inertia and centrifugal force. Some droplets are thrown away and gathered to a certain extent, and move downward to the washing tank under the action of gravity, while the solid matter remaining on the demister blades is recovered to the washing tank through the flushing liquid.

[0003] In the prior art, demisters generally do not have additional components for cleaning the scale on the demister blades. Incomplete cleaning of the scale will cause the demister channel formed between adjacent demister blades to become smaller, thereby affecting the demisting effect. Moreover, more scale will also cause the demister blades to collapse and deform. Therefore, the utility model proposes a demister device suitable for a desulfurization absorption tower to solve the deficiencies in the prior art. Utility Model Content

When the defogger device of the utility model which is suitable for a desulfurization absorption tower performs defoggering, the flue gas flows through the defogger device from bottom to top, and the flue gas is acted upon by the deflector blades 2 in the defogger channel 3. The droplets carried in the flue gas are collected and move downward to the washing tank under the action of gravity. When the deflector blades 2 need to be scaled, the connecting seat 6 is moved on the slide rod 5 by toggling the connecting seat 6. During the process, the first descaling scraper 7 and the second descaling scraper 8 connected to the connecting seat 6 move synchronously.
