Description
The utility model relates to a kind of electrostatic precipitator.
The present electrostatic precipitator of generally using, its anode construction assembles through cold rolling thin plate with polylith usually, and the processing and manufacturing required precision is very high, and the installation, maintenance difficulty is big.Often, the distortion of anode scraps because of causing the die opening deviation to cross ambassador's anode.The anode deformation reason has the problem of design, manufacturing, installation, and the problem in the use is also arranged.As, flue-gas temperature is too high, the carbon monoxide blast, and dust-collecting and vibratings etc. are all multifactor, can both make the anode distortion.
Reducing reentrainment of dust is one of factor that improves efficiency of dust collection.The main cause that produces reentrainment of dust has these points: collect the back corona phenomenon that high resistivity dust causes, the eddy current that anode surface high speed electric wind forms, influence of vibration dust-cleaning or the like.
The common electrical deduster importing and exporting the airflow uniform distribution device that all is provided with complexity, still often because of the air-flow skewness, influences dust removing effects.The electrostatic precipitator of square cartridge structure is also arranged recently both at home and abroad, but be only limited to vertical middle the use, its essential characteristic is identical with the common electrical dedusting.
The high pressure resistant insulation material adopts the material of porcelain bushing shell or this not anti-vibration of class of rod, mostly for preventing that dewfall from also needing to heat with powerful electrothermal tube outside.
The purpose of this utility model is, provides a kind of and does insulation with the compound inslation device and isolate, and that anode divides is main, pay anode, and main anode is the square tube two-region electrostatic precipitator of side band porous, this structure vertical and horizontal in all be suitable for.
The purpose of this utility model is achieved in that square tube two-region electrostatic precipitator, is made up of deduster body and electric supply installation two parts.Body part, anode divide main anode and pay an anode, and main anode is the shaped steel of multilayer criss-cross arrangement or nonmetallic materials a plurality of square tubes that are formed by connecting, and square tube central authorities hang a seizing wire and do corona wire.Corona wire is suspended in the top of deduster with the compound inslation device.
When dust-contained airflow passed through the main anode square tube, the gas between each can be ganged up and be made the air-flow distribution more even, and square tube also can be done access path, is easy for installation and maintenance.Take square cartridge structure to have stronger self-supporting effect, high temperature resistant, not yielding, can save the big parts of steel quantity consumption such as the column in the common electrical deduster, big Beam.In horizontal, the porous net of square tube side is the special role that gas channel has similar transverse collecting plate, so inertia gathers dust and also play a role therein, has improved dust-collecting efficiency; Main anode is only born the effect of heavy collection dust, and dust deposition can fall by deadweight to certain thickness generally speaking, and sticking dust will add rapping, and rapping intensity and frequency are all low than conventional electric cleaner.
Pay anode with corrosion-resistant, resistance to wear, high-intensity good conductor makes, as Stainless Steel silk etc., be installed in main anode square tube side and parallel with the square tube side and certain distance arranged, pay anode and corona wire and keep strictly equidistant, making has good corona discharge, and the very strong electric wind of generation keeps clean its surface between the two, can avoid forming eddy current and producing back corona phenomenon on the main anode surface, can collect high resistivity dust, for satisfying the requirement of various dedusting conditions, distance between the two also can be adjusted arbitrarily.
The compound inslation device is formed by changeing electrical heating elements in the metal tube external application polytetrafluoroethylmaterial material.One end of metal tube is linked to each other with corona wire by polytetrafluoroethylene (PTFE) is coated, and other end opening dress electrical heating elements links to each other with dust remover roof.
Owing to adopted such scheme, this deduster can be handled high-temperature flue gas and high resistivity dust, reduces reentrainment of dust, and is simple in structure, with low cost, the efficiency of dust collection height.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the vertical section structure sketch of square tube two-region first embodiment of electrostatic precipitator.
Fig. 2 is the vertical section structure sketch of second embodiment of square tube two-region electrostatic precipitator.
Fig. 3 is that the K of Fig. 2 is to diagrammatic cross-sectional view.
Fig. 4 is the A-A cutaway view of Fig. 1.
12. decanting zones, 1. insulating bar 2. corona wires, 3. horizontal main anode 4. vertically main positive plate 5. pairs of anodes, 6. air inlets, 7. air outlet 8. high pressure entrance holes, 9. horizontal gas distribution grid 10. vertical gas distribution grid 11. corona zones among the figure
In Fig. 1,2, corona wire (2) is to link to each other with dust remover roof by insulating bar (1), and keeps insulation to isolate.The negative pole of high voltage source links to each other with corona wire (2) by entrance hole (8).Laterally main anode (3) is staggered with vertical main anode (4) layering and connects into the square tube of a plurality of band mesh, and square tube links to each other with shell and ground connection links to each other with the positive pole of high voltage source.
In Fig. 4, the position of fixing point makes both keep equidistant to corona wire (2) by adjusting separately up and down with paying anode (5).And the range deviation of main anode (4) and corona wire (2) can change in the larger context, and efficiency of dust collection is not had big influence.
