Abstract
The utility model is a kind of shower nozzle for flue gas washing purification, comprises mounting flange 1, scroll 2, closure plate 3, angle limiter 4.Mounting flange 1 and angle limiter 4 form the cavity of an annular, for arranging scroll 2.Scroll 2 is hollow structure, and the shape of scroll 2 meets the screw structure of constant pitch.Closure plate 3 is connected in the middle part of scroll 2, the import 21 of scroll 2 and outlet 22 is separated.Scroll 2 and angle limiter 4 form the eddy flow chamber 43 of a column; Angle limiter 4 is provided with spout 42 and a conical rectification face 41 of an annular.Liquid flows into spiral inlet 21 from feed tube, and liquid constantly rotates in scroll 2, flows out, then, enter the eddy flow chamber 43 of column from scroll outlet 2, and liquid accelerates to rotate in eddy flow chamber 43, rotates ejection from spout 42.After conical rectification face 41 rectification of angle limiter 4, drop is the ejection of coniform mist shape according to special angle.
Description
Technical field
The utility model relates to a kind of shower nozzle, in particular, is a kind of flue gas washing purification shower nozzle.
Background technology
Along with the development of national economy, atmosphere pollution is more and more serious, the SOx especially in air and pellet, and very large to human health damage, in order to curb environmental pollution, each industrial enterprise has built various desulfurization and dust removal equipment.In desulfurization and dust removal equipment, flue gas, after preliminary desulfurization and dedusting, often containing some globule and acid mist, if directly discharge air, will be wasted a large amount of fresh waters and weaken the desulfuration efficiency of desulfurization equipment.
In order to catch the globule in flue gas and acid mist, save the consumption that flue gas desulfurization facilities runs, at flue gas after the preliminary treatment of desulfurization and dedusting unit, then one group of flue gas washing purification shower nozzle is set.Shower nozzle forms coniform distribution after being atomized by akaline liquid, alkali mist with rise that flue gas that inflator rises is reverse to be contacted.The droplet size of shower nozzle ejection is suitable, after alkali droplet contacts with the large water drop containing acid in flue gas, can wash containing sour water pearl.Namely can catch a part of sulfuric acid mist, improve the operational efficiency of desulfurization equipment, a part of water can be reclaimed again, reduce the fresh water consumption of desulfurization equipment.
Flue gas washing shower nozzle needs spray pattern alkali droplet being dispersed into special angle, and conventional atomizing nozzle, is mostly standard component, and spray angle is difficult to the requirement adapting to flue gas washing.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of shower nozzle with the accurate flue gas washing purification of spray angle, makes alkali droplet namely better can cover exhaust gases passes, is unlikely to again to interfere with each other.
Task of the present utility model realizes like this.Its structure is primarily of mounting flange, scroll, closure plate, angle limiter composition.Mounting flange has sealing surface and bolt hole, one end is connected with feed pipe, and one end is connected on angle limiter, and mounting flange and angle limiter form the cavity of an annular, for arranging scroll.Scroll is hollow structure, and the vortex filament of scroll 2 is helical form, and the feature of helical is equal diameter constant pitch.The scroll spiral number of turns is 0.8 ~ 1.2 circle.Closure plate is connected in the middle part of scroll, the import of scroll and outlet is separated.Scroll and angle limiter form the eddy flow chamber of a column; Angle limiter 4 is provided with spout 42 and a conical rectification face 41 of an annular, the optimum range of the diffusion angle β in conical rectification face 41 is 50 ° ~ 90 °, the outside wall surface in conical rectification face adopts the coating process of acid-alkali-corrosive-resisting, and internal face adopts wear-resistant coating process.
Its operation principle is, is connected on feed tube by shower nozzle by mounting flange, and liquid flows into scroll import from feed tube, liquid constantly rotates in scroll, flows out from the outlet of scroll, then enters the eddy flow chamber of column, liquid accelerates to rotate in eddy flow chamber, then sprays from nozzle outlet rotary.After the conical rectification face rectification of angle limiter, drop is the ejection of coniform mist shape according to special angle.
The utility model proposes a kind of flue gas washing purification shower nozzle, the advantage of employing such scheme is: 1, structure is simple, reliable, and anti-blockage capability is strong; 2, spray angle is fixed, and designs simple and efficient; 3, atomization quality is stablized; 4, easy to process, cost is low; 5, wear-resistant.

Detailed description of the invention
As shown in Figure 1, the utility model is a kind of flue gas washing purification shower nozzle, comprises mounting flange 1, scroll 2, closure plate 3, angle limiter 4.Mounting flange 1 has sealing surface and bolt hole, one end is connected with feed pipe, and one end is connected on angle limiter 4, and mounting flange 1 and angle limiter 4 form the cavity of an annular, for arranging scroll 2.Scroll 2 is hollow structure, and the shape of scroll 2 meets the screw structure of constant pitch.Closure plate 3 is connected in the middle part of scroll 2, the import 21 of scroll 2 and outlet 22 is separated.Scroll 2 and angle limiter 4 form the eddy flow chamber 43 of a column; Angle limiter 4 is provided with spout 42 and a conical rectification face 41 of an annular.
The course of work of this flue gas washing purification shower nozzle is: be connected on feed tube by shower nozzle by mounting flange 1, liquid flows into spiral inlet 21 from feed tube, liquid constantly rotates in scroll 2, flow out from scroll outlet 2, then, enter the eddy flow chamber 43 of column, liquid accelerates to rotate in eddy flow chamber 43, rotates ejection from spout 42.After conical rectification face 41 rectification of angle limiter 4, drop is the ejection of coniform mist shape according to special angle.
