Abstract

A novel demister combined unit is formed through combing a demister element and short end plates, wherein the short end plates in each combined unit are connected through dowel pins and holes integrated with the short end plats, or the short end plates are connected through independent connecting bars, so as to form an integral demister module. The conventional demister module consists of a plurality of demister elements and one demister end plate, the end plate of the demister is combined with the demister elements through welding or rod penetration, as the efficiency of welding or rod penetration is very low, the assembly cost of the demister is high, and the demister elements are difficult to maintain; various demister devices of a flue gas desulfuration absorption tower necessary for a fuel electric plant include multi-layer and multi-row demister modules; and through the adoption of the demister module formed by the novel demister combined units, only a single demister combined unit rather than the entire demister module is required to be replaced, thereby reducing the manufacturing and maintaining cost of the demister; and the novel demister combined unit has very high application value in the desulfuration and environmental protection field for fuel electric plants.

Summary of the invention

[0003] purpose of the utility model is: a kind of demister assembled unit is provided; By its assembling demister modules; Needn't adopt traditional welding or wear bar mode, make and reduce demister device assembling and easy to maintenance the Coal,steam plant with FGD absorption tower and make and maintenance cost.

The utility model is achieved in that a kind of demister assembled unit, and it is combined by demister element and short end plate; According to demister circuit elements design spacing; Be divided into a plurality of short end plates to long demister end plate, each short end plate connects through the pin of self set, perhaps connects through independent pitman; Form whole demister modules; A plurality of demister modules are formed one and are got rid of days with fog, a row or get rid of day with fog more and form one deck demister, and one or more layers demister constitutes demister device.

As a kind of preferred structure of the utility model, short end plate body appearance profile and demister element profile curve are same or similar, and a side of short end plate is arranged pin or hole, the perhaps combination in pin and hole, the hole arranged or pin of opposite side, the perhaps combination in pin and hole.

As the further preferred structure of the utility model, short end plate body appearance profile and demister element profile curve are inequality also dissimilar, adopt other shapes; One side of short end plate is arranged pin or hole; The perhaps combination in pin and hole, the hole arranged or pin of opposite side, the perhaps combination in pin and hole.

As the further improvement of above-mentioned preferred structure, the both sides of short end plate pin or hole, or pin is with the hole combination with lack end plate not on same plane.

In above-mentioned various structures, can also be all hole arranged in the both sides of short end plate, adopt independent pitman to assemble.In above-mentioned various structures, a demister end plate part adopts split-type design, and a part adopts global design; Or

The inboard split-type design of person's demister end plate, global design is adopted in the outside.

The beneficial effect of the utility model makes the welding of having omitted demister element and demister end plate on the demister packaging technology or wears rod work, has improved packaging efficiency; Can change single demister assembled unit and need not to change whole demister modules, reduce user's cost of equipment maintenance.

Specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:

Fig. 1, Fig. 2 are demister combination unit structure figure, and it is combined by demister element 1 and short end plate 2, according to the design pitch of demister element 1; Be divided into a plurality of short end plates 2 to long end plate, single demister element 1 is formed single demister assembled unit with single short end plate 2, and a plurality of demister assembled units are connected with the hole through the pin of self gathering by short end plate 2; Perhaps connect through independent pitman; Form whole demister modules, as shown in Figure 3,21 is hole or pin among the figure.

First kind of embodiment of said demister assembled unit is as shown in Figure 4; 21 is hole or pin among the figure; Its short end plate 2 body appearance profiles and demister element 1 contour curve are same or similar, and a side of short end plate 2 is arranged pin or hole, perhaps the combination in pin and hole; Hole arranged or the pin of opposite side, the perhaps combination in pin and hole.

Demisting on temperature of the second embodiment of the combining unit shown in Figure 5, the figure 21 is a hole or pin, the short end plate 2 and the defogger body contour element 1 neither identical nor similar to the contour curve, Bian with other shapes, the short side of the end plate 2 disposed pin or hole, or a combination of pins and holes, the other side of the hole or pin arrangement, or a combination of pins and holes.

The third embodiment of said demister assembled unit is as shown in Figure 6, and 21 is hole or pin among the figure, is with first, second kind embodiment difference: the both sides pin or the hole of short end plate 2, or pin is with the hole combination with lack end plate 2 not on same plane.
