Abstract

A defogger comprises a module, a support beam, wash pipelines, a clamping strip and a blade. The defogger is a flat plat type defogger, i.e. the defogger is horizontally arranged on the support beam, and the blade is of a traverse baffle type. The pipelines in a wash system of the defogger is made of a modified fiber reinforced polypropylene (FRPP) material, and a layer of glass fiber reinforced plastic (FRP) material is wrapped outside each pipeline so as to improve the high temperature resistance and the antiseptic performance of the pipelines and well improve the strength of the pipelines. Each section of pipeline is connected by a thread pipe sleeve so as to improve the flexible installation of the pipelines and the reliability of the connection of the pipelines. The blade structure adopts the traverse baffle type, and a turning point is designed to be non-circular transition, so that the defogging efficiency can be obviously improved. The blade assembly adopts the clamping location so as to improve the assembling efficiency and the stability of the whole structure. The pipelines of the wash system are externally provided with the glass fiber reinforced plastic material so that the performances in high temperature resistance, the corrosion resistance, and the like of the pipelines are improved. The utility model has both excellent performance and quality.

Description

Demister

Technical field;

The utility model relates to the improvement of demister structure, is mainly used in fields such as electric power, chemical industry and metallurgy.

Technical background;

The major function of demister is to remove behind shower droplets entrained in the flue gas, to prevent producing fouling and corrosion in flue and chimney, also avoids slurries to produce " raining " phenomenon in the exit.The design of demister is to make according to principles such as inertia, centrifugal force, bump, centrifugal force.Blade module is rearranged by two parallel passages or triple channel blade.Because the design of blade shape is compelled to change direction by the interlobate flue gas that contains liquid through several times.When this takes place, because flue gas has certain flow velocity, make the drop in the flue gas produce inertia and centrifugal force, heavier drop is got rid of on the wet wall of blade, be integrated in the laminar flow then and outflow.By these two kinds of mechanism (stir with the surface and contact), the drop in the flue gas is separated, reach the effect of demist.

Summary of the invention;

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high strength, long service life, novel flat demister are provided.

Goal of the invention of the present utility model is achieved in that a kind of demister; Comprise by module (1), brace summer (2), flushing line (3), card article (4) and blade (5) and forming that the utility model blade is the baffling template, it makes simple and easy, easy for installation.Adopt the vane thickness of 3mm simultaneously, can significantly improve its intensity, prolong its service life.Because it has a plurality of flex points, force flue gas can repeatedly carry out break-in and flow, the droplet in the flue gas can better be removed, can significantly improve demist efficient.Compare other forms of demister, its demist efficient is improved, and the droplet content in the flue gas significantly reduces, and has reduced the possibility of flue and chimney fouling, corrosion, also can better avoid slurries to produce " raining " phenomenon at smoke outlet simultaneously.Blade is assembled into module by the card article location again, welds the PP plate on its both sides, has just formed elementary cell---the module of demister.Form demister by module spliced one by one again.All leaving certain gaps uncovered by the economic plans in advance on blade and the card article as long as find the relevant position during installation, are beaten into earlier, weld at its interface again.Can assemble the blade and the card article of different numbers by designing requirement, form the different module of lobe numbers.The employed module of the utility model mainly is that blade pitgh is 20 millimeters and 40 millimeters, and lobe numbers is respectively two kinds of modules of 21 and 11.Be divided into standard and non-standard module in these two kinds of modules again.Blade pitgh is that 20 millimeters standard module length is 2 meters, and width is 439 millimeters, highly is 180 millimeters; Blade pitgh is that 40 millimeters standard module length is 2 meters, and width is 420 millimeters, highly is 180 millimeters.The length of non-standard module and wide size are unfixing, highly all are 180 millimeters.

Pipeline in the utility model demister rinse-system is to be made by the MODIFIED PP material, twines one deck FRP material in its outside again, improves its high temperature resistant and erosion-resisting performance.Also well improved simultaneously its intensity.

The utility model demister and rinse-system thereof can significantly improve demist efficient, and can be good at considering its performance such as high temperature resistant, anticorrosive.Accomplish that performance and quality hold concurrently excellent.

The specific embodiment;

The utility model patent mainly is to be used in the heat-engine plant wet desulphurization system, in order to remove the moisture of carrying secretly through in the flue gas behind the spraying layer.Be installed in the top of desulfurizing tower.It mainly contains the demister body and rinse-system two parts are formed.Fig. 1 and Fig. 2 represent demister body and rinse-system respectively.The layout of demister is made of two-layer demister body and flushing line respectively as shown in Figure 3.Generally the upper and lower sides at the demister body all will be provided with flushing line, i.e. four layers of flushing line.Situation about also having is not arrange the flushing flushing line at the top one deck, that is to say only to arrange three layers of flushing line.During work, the flue gas with certain flow rate is through demister, removes moisture in the flue gas by the above-mentioned operation principle of mentioning.Also carry some other impurity in the flue gas secretly, in the blade surface fouling of demister, increase the flow of flue gas resistance easily, and influence the normal operation of whole system.Rinse-system prevents the blade surface fouling exactly, washes according to washing water quantity that designs in advance and flush sequence.The flushing operation of rinse-system generally is automatic control.Also can manually wash if any special circumstances.
