Background technology
Electric cleaner is the corollary equipment of flue gas ash removal and material recycle indispensability in the industrial departments such as thermal power plant, metallurgy, chemistry and cement, particle flue dust in flue gas is removed or is reclaimed by its function, thus significantly reduce the fume amount entered in atmosphere, this is that environmental protect pollutes, and improves the important environmental protection equipment of air quality.When its operation principle is flue gas by flue before electric cleaner agent structure, make its flue dust electrically charged, then flue gas enters the electric cleaner passage arranging opposite electrode.Due to electrically charged flue dust and the mutual suction-operated of contrary electroplax, make the particle flue dust in flue gas be adsorbed on electrode, then the particle on electrode is removed, thus reach the object of the flue dust removed in flue gas.It can divide dry electrostatic cleaner, wet cottrell, vaporific particle electrostatic catcher and half wet cottrell by purge mode difference.
Wet cottrell makes dust collecting electrode surface form water membrane, by the electric cleaner that the dust of heavy collection on pole plate washes away by modes such as water spray or overflow waters.Its principle of gathering dust is identical with the dust-cleaning principle of dry electrostatic cleaner, and be all make dust charged by high-voltage corona discharge, the dust after charged reaches collecting electrode under the effect of electric field force.Wet type deashing can be avoided having trapped flying upward again of dust, reaches very high efficiency of dust collection, therefore also for the recycling to dust.Because of without rapping apparatus, run also more reliable.But it is fast that current wet cottrell also exists equipment corrosion, and electrode life is short, and dedusting effect is than low problem.
Utility model content
The purpose of this utility model is for problems of the prior art, and provide a kind of equipment corrosion degree low, electrode life is long, the wet static dedusting device of the efficient corrosion resisting that operating efficiency is high.
The wet static dedusting device of the utility model efficient corrosion resisting, comprises side and arranges housing 2 into mouth 1, and be arranged on the flusher in housing 2 from top to bottom, dust arrester and air-distribution device; Housing 2 top arranges exhaust outlet, and bottom arranges sewage draining exit; It is characterized in that, described dust arrester comprises the upper suspension 3 and lower suspension 4 that are fixed on housing 2 inside, and is evenly distributed on the some electrodes between suspension 3 and lower suspension 4; Electrode is connected with the insulator box 5 being arranged on housing 2 top, and electrode comprises the receiving electrode 6 on top and the corona discharge electrode 7 of bottom; Corona discharge electrode 7 lower end is arranged through lower suspension 4, and is connected with sacrificial anode block 8 respectively.
Further, housing 2 side of described sacrificial anode block 8 correspondence is provided with inspection manhole 9.
Further, described air-distribution device comprise airflow-distribution board 10 and corresponding enter the gas-flow deflector 11 that is obliquely installed of mouth 1; Airflow-distribution board 10 totally two, and be horizontally set between gas-flow deflector 11 and electrode successively; The side that gas-flow deflector 11 is relatively high is hinged on housing 2 sidewall above mouth 1, and the other end is connected with housing 2 by slidable adjustment device 12.
Further, housing 2 sidewall between described gas-flow deflector 11 and airflow-distribution board 10 is provided with safety explosion-proof valve 13.
Further, described flusher comprises the continuous water feeding device 14 be successively set on above electrode and washs jet pipe 15 with regular.
The wet static dedusting device of the utility model efficient corrosion resisting, the protection of physical preservation can be realized to electrode by the sacrificial anode block 8 being arranged on electrode lower end, in the loss of electrode, be mainly electrochemical corrosion, in existing equipment, electrode directly act as the anode in electrochemical reaction, by fast corrosion, the present sacrificial anode block 8 increased that utilizes just can ensure corrosion to shift, thus the protection achieved electrode, greatly reduce the consumption of production, slow down the maintenance of equipment; Flue gas is avoided to the direct shock of housing 2 and damage again by the setting of gas-flow deflector 11, improve velocity of flue gas, thus ensure that flue gas pass through efficiency, and can carry out preliminary rectification after air-flow angle being carried out to regulating guarantee air-flow and entering housing 2, then utilize airflow-distribution board 10 pairs of air-flows further to distribute and homogenizing; Its beneficial effect is, reasonable in design, and structure is simple, safe and reliable, long service life, safeguards simple, easy to operate, environment-friendly high-efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation described in the utility model example.
In figure: enter mouth 1, housing 2, upper suspension 3, lower suspension 4, insulator box 5, receiving electrode 6, corona discharge electrode 7, sacrificial anode block 8, inspection manhole 9, airflow-distribution board 10, gas-flow deflector 11, slidable adjustment device 12, safety explosion-proof valve 13, continuous water feeding device 14, regularly washing jet pipe 15.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further explained and illustrated.
The wet static dedusting device of the utility model efficient corrosion resisting, as shown in Figure 1, it comprises side and arranges housing 2 into mouth 1, and is arranged on the flusher in housing 2 from top to bottom, dust arrester and air-distribution device; Housing 2 top arranges exhaust outlet, and bottom arranges sewage draining exit; Wherein, as shown in Figure 1, dust arrester comprises the upper suspension 3 and lower suspension 4 that are fixed on housing 2 inside, and is evenly distributed on the some electrodes between suspension 3 and lower suspension 4; Electrode is connected with the insulator box 5 being arranged on housing 2 top, and electrode comprises the receiving electrode 6 on top and the corona discharge electrode 7 of bottom; Corona discharge electrode 7 ionizes charged for giving the soot dust granule in the flue gas that rises under the effect of high electric-field intensity, and moves to receiving electrode 6, due to receiving electrode 6 and corona discharge electrode 7 institute on the contrary electrically charged, so electric discharge becomes neutral and is gathered on receiving electrode 6 on receiving electrode 6; Corona discharge electrode 7 lower end is arranged through lower suspension 4, and is connected with sacrificial anode block 8 respectively; When there is electrochemical corrosion, sacrificial anode block 8 corrodes, thus protects electrode and can not corrode, only need regular sacrificial anode block 8 is cleared up and is changed just can play fabulous antisepsis.Housing 2 side of sacrificial anode block 8 correspondence is provided with inspection manhole 9.
