Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, in the utility model embodiment, a kind of anti-edge effect circle, to comprise on conical ring girth sheets 2 and rubber slab 3 under girth sheets 1, conical ring; On described conical ring, one end of girth sheets 1 is fixedly connected with the tower wall of spray column, and under the other end and conical ring, girth sheets 2 is welded and fixed, and on conical ring, under girth sheets 1 and conical ring, girth sheets 2 is cone-shaped ring structure; Under described taper, one end of girth sheets 2 is connected with the tower wall of spray column, the other end is connected with girth sheets in taper 1, and be in the below of girth sheets 1 in taper, close to center, at an angle between girth sheets 2 under girth sheets 1 and taper in taper, the round edge of girth sheets 1 in taper is given prominence to, girth sheets 2 design in body structure under girth sheets 1 and taper in taper; After described rubber slab 3 and girth sheets 1 in taper are fitted, utilize set bolt 5 and nut 4 to be connected at rubber slab 2 and the two ends of girth sheets in taper 1, in whole taper on girth sheets 1 annulus, set bolt 5 and nut 4 are uniformly distributed in the form of a ring.
Shower nozzle sprays slurries at a certain angle, tackled by the rubber slab on girth sheets on anti-edge effect circle conical ring before not reaching wall, the slurries splash spray mist group with certain angle of reflection Jian Xiang center high density, the slurries pressure conical ring edge flowed down along conical ring forms an annular " cascade ", the air-flow of tower mural margin is because the effect of enclosing under anti-edge effect circle is to tower centre pilot, air-flow meets again the stop of the slurries that circle splashing has been reflected on conical ring through annular " cascade ", the air-flow that edge rises is made also to obtain the abundant mixing with slurries, to contact density suitable with central gas stream, every layer of spraying layer desulfuration efficiency is improved, the entirety finally reaching desulfuration efficiency improves, under equal desulfuration efficiency, can effectively reduce " liquid-gas ratio ", desulphurization system energy consumption is reduced, also the cost of investment of identical desulfurizing tower can greatly be reduced.Upper circle is pressed close to install rubber slab, makes circle more shock-resistant and wash away, and the angle of upper circle and rubber slab coordinate makes circle be difficult to long-pending gypsum, and again because the high speed impact of shower nozzle spray, gypsum is also difficult to be formed; Simultaneously because angle of reflection is reasonable, the slurries of splashing seldom splash wall, and therefore wall is washed away very little, anticorrosive coat life, and also because the impact of angle, wall and upper circle angle are difficult to pile up gypsum.The antiwear characteristic of rubber slab, make upper circle herein keep longer life-span and long-term anti-edge effect, rubber slab is convenient for changing, and to make in desulfurizing tower anticorrosive coat herein be subject to continuous print protection.
