Abstract
The utility model relates to a wet-type two-stage swirling-flow desulfurization dust remover, belongs to a desulfurization dust remover. The desulfurization dust remover comprises a lower cone body, an external barrel body, a smoke inlet, a smoke outlet, a circulating fluid inlet, and a cone body, and is characterized in that a swirling-flow guide board is added and arranged at the lower part of the smoke inlet, the external edge of the swirling-flow guide board is provided with 3 to 90 swirling-flow guide blades which present an angle of 15 to 45 degrees with the horizontal. The dust remover has the advantages that the structure is novel, and the dust remover is suitable for the desulfurization, dedusting, and purification of the boiler smoke and the industrial waste gas. The dust removal efficiency reaches more than 95 percent, the efficiency of the desulfurization is obviously increased, and the exhausted smoke after the purification does not carry liquid, thereby, meeting the requirements of the environmental protection.
Description
Technical field
The utility model belongs to a kind of and the matching used desulfurizing dust-collector of boiler.
Background technology
General wet type desulfurizing dust collector after flue gas to be clean enters in the device, mixes with hydraulic fluid impact in the device at present, carries out desulfurization and dedusting, discharges through the top exhanst gas outlet then.This desulfurizing dust-collector, purification efficiency is low, and discharges flue gas and carry liquid and work the mischief.
Summary of the invention
The utility model provides a kind of wet type twin-stage cyclone desulfuration deduster, and is low to solve the purification efficiency that present desulfurizing device exists, and discharges flue gas and carry the problem that liquid works the mischief.The technical scheme that the utility model is taked is: comprise lower cone, outer cylinder body, gas approach, exhanst gas outlet, circulation fluid import, cone, set up an eddy flow guide plate below this gas approach, this eddy flow guide plate outer rim has 3～90 eddy flow guide vanes that become 15～45 degree angles with horizontal plane.
In the utility model, on cone, install a drum shape rotational flow separation tube additional, this rotational flow separation tube be provided with 3～48 with radially become 25～75 the degree angles the eddy flow guide vane.
When the utility model uses, liquid level is controlled at a Metacentre Height by the fluid infusion groove in the device, after flue gas enters, under the effect of eddy flow guide plate, high-speed rotational is impacted to the bottom liquid level, flue dust is used to power centrifugal sedimentation according to it, meanwhile rotating the flue gas stream that dashes down at a high speed makes bottom hydraulic fluid eddy flow splash again, gas-liquid is fully mixed contact and is carried out desulfurization and dedusting, thereafter rotation is risen and is entered the rotational flow separation tube of device internal upper part, under centrifugal action, realizes gas-liquid separation, liquid is through upper cone, down-comer, be back to the bottom, clean flue gas is discharged from smoke outlet tube, falls within the flue dust at the bottom of the device, can intermittently discharge by sewage draining exit, or with the mobile discharge continuously of periodic duty liquid, hydraulic fluid can be interrupted to replenish or circulate continuously and add.
The utility model advantage is: novel structure is suitable for the desulfurization dust separation of boiler smoke and industrial waste gas.Efficiency of dust collection is up to more than 95%, and desulfuration efficiency significantly improves, and the flue gas of discharging after purifying does not carry liquid, compliance with environmental protection requirements.

The specific embodiment
Comprise outer cylinder body 3, lower cone 2 is fixedlyed connected with this outer cylinder body bottom, there is sewage draining exit 1 this lower cone below, exhanst gas outlet 10 is arranged at its top, there is fluid infusion groove 13 below of outer cylinder body, and gas approach cylindrical shell 11 is arranged on the outer cylinder body, and gas approach 4 and shower plate 6 are arranged on it, circulation fluid import 5 is connected with shower plate 6, and eddy flow guide plate 12 is fixedlyed connected with gas approach cylindrical shell 11;
Cyclone separator 9 is positioned at the outer cylinder body upper interior, its fixedly connected cone 8 in below, the fixedly connected down-comer 7 in this cone bottom.
Wherein: the outer rim of eddy flow guide plate has 3～90 eddy flow guide vanes that become 15～45 degree angles with horizontal plane.Its preparation method is: mark 3～90 tangent lines with the even layout that radially becomes 15～miter angle with circular dull and stereotyped along center circle, by tangent line flat board is severed, again with the each several part of severing, remove respectively and change into the eddy flow guide vane that becomes 15～miter angle with the plane, formation can make the descending passage of flue gas eddy flow.
In the present embodiment be with the evaporation capacity boiler of 4T/h supporting be example, 16 of eddy flow guide vanes, 45 jiaos of blade and horizontal plane angles.
The rotational flow separation tube first half be provided with 3～48 with radially become 25～75 the degree angles the eddy flow guide vane, its method for production is that vertical and transverse cut are evenly marked along circumference in bucket top, sever along the line, to sever part again and remove the eddy flow guide vane that changes into and radially become 25～75 degree angles, formation can make the flue gas eddy flow enter the interior passage of tube.
In the present embodiment, 12 of rotational flow separation tube eddy flow guide vanes, blade and 60 degree of angle radially.
