Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in figs. 1 to 6, a kind of run-in index demister, comprises equilateral hexagon cylindrical shell 1, is arranged at the parallel compounded plate group 2 of bottom in equilateral hexagon cylindrical shell, and is arranged at the wash tub pipe assembly 3 of equilateral hexagon cylindrical shell internal upper part.According to actual conditions, multiple demister of the present utility model can be adopted, during concrete operations mode, multiple demister is connected successively from top to bottom, arrange grid type demister support at side to be fixed, make each demister of the present utility model keep up and down near, thus realize relatively fixing, thus meet required demist effective area.
When using the utility model, flue gas is entered by the bottom of demister, upwards flows, and reaches dedusting, demist effect through parallel compounded plate group; Meanwhile, the flue gas flowing through parallel compounded plate group forms eddy flow in equilateral hexagon cylindrical shell, causes remaining most of dirt, mist in flue gas to invest on barrel, and with barrel downstream to slurry pool.
Particularly, it is orthohexagonal cylindrical shell 11 that described equilateral hexagon cylindrical shell comprises cross section, and is arranged at the fixture 12 for fixing parallel compounded plate group on cylinder lateral wall; The end of described parallel compounded plate group is then fixed on fixture.Parallel compounded plate group can be fixed on bearing, easy installation and removal by above-mentioned setting.
Described parallel compounded plate group comprises regular hexagon frame 21, and is arranged at several blades 22 in regular hexagon frame; All blade leans are arranged, and parallel each other.Wherein, described blade is arc shaped blade or ridge type blade; When for arc shaped blade, the angle β between arc shaped blade and horizontal plane is 20 ° ~ 50 °, and when for ridge type blade, the angle β between ridge type blade and horizontal plane is 70 ° ~ 98 °.By above-mentioned restriction, flue gas is through parallel compounded plate group, due to special design make dirt, mist is more prone to is removed, easier formation eddy flow when flue gas also can be made upwards to flow, thus greatly increases dedusting of the present utility model, demist effect.Certainly in order to control flue gas flow rate further, (namely each demister joint) can add guide ring between multiple demister of the present utility model, thus can control the flow velocity of flue gas through each demister, that improves each demister removes fog effect.
Due to dust-laden in flue gas, reach a certain amount of containing mist, after demister, part dirt, mist can accumulate in parallel compounded plate group and equilateral hexagon cylinder inboard wall.For preventing longtime running fouling, blocking, wash tub pipe assembly is also set in the utility model.Carry out interruption by wash tub pipe assembly to parallel compounded plate group and equilateral hexagon cylindrical shell to rinse, thus avoid fouling, clogging generation, improve dedusting accordingly, except fog effect; Rinse break time and rinse and continue duration, then regulate as the case may be.
But above-mentioned wash tub pipe assembly concrete structure is as follows: the wash tub pipe 31 that described wash tub pipe assembly is arranged along cylinder inboard wall, the wash tub pipe joint 32 be connected with wash tub pipe, and be arranged at the flushing spray-hole 33 on wash tub pipe sidewall.Preferred as one, described wash tub pipe is furnished with two rows and rinses spray-hole, a row is for rinsing parallel compounded plate group, and another row is for rinsing cylinder inboard wall.As shown in Figure 6, wash tub pipe is regular hexagon framework.
What deserves to be explained is, the female pipe of water inlet supplied water for the utility model is positioned at the bottom of whole device when reality supplies water, thus conveniently to install, run, maintenance.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some making on the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
