Description
Technical field
This utility model relates to a kind of wet type electric demisting device with conductive fiberglass reinforced plastic bilayer water conservancy diversion orifice plate.
Background technology
At present, along with country's reinforcement to environmental requirement, particularly metallurgy industry, at sintering, pelletizing etc. a large amount of new on desulfurizing item in, many is all to use wet process of FGD.Along with the enforcement successively of project, bring again another serious problems, it is simply that the phenomenons such as acid rain, gypsum rain occur in many wet desulphurizations, severe contamination surrounding.High-efficient wet-type electrostatic precipitator is used can effectively to remove this type of phenomenon.Desulfurization in power industry at present is just used.Metallurgy industry is also at the early-stage, and prospect is widely.
Wet electrical dust precipitator grows up on the basis of dry electric precipitation device.Owing to its efficiency of dust collection is high, be applicable to the process containing high resistivity dust flue gas, and can purify some harmful gas, therefore, wet electrical dust precipitator has large development in recent years.The version of wet electrical dust precipitator and dry electric precipitation device have bigger improvement, but in cleaner unit, the charged mode of grit, dust principle and gas solid separation process etc. are all similar to dry electric precipitation device.
Enter the flue gas before wet electrical dust precipitator, typically will be humidified in spray tower or entrance diffuser, and be allowed to saturated.After saturated flue gas enters electric field; grit or droplet in air-flow bring electric charge soon, shift to collecting electrode under the effect of electric field force, and the droplet being attached on pole plate connects in flakes; forming liquid film, liquid film is fallen in the mud ditch of cleaner unit bottom under gravity together with grit.
Wet method deashing is one of wet electrical dust precipitator feature of being different from dry electric precipitation device.Owing to wet electrical dust precipitator is to utilize the liquid film current on pole plate to understand dust, it is not necessary to rapping apparatus, it is thus eliminated that the secondary fly-up of dust, improve efficiency of dust collection.
Owing to wet electrical dust precipitator has the effect of dedusting and purifying harmful gas concurrently, therefore, this electric cleaner is in addition to the occasion that can be used for high resistivity dust, abroad it is used for the purification of electrolytic aluminium plant smoking gas containing fluorine, in order to remove the aluminum oxide dust in flue gas, the harmful gas such as fluohydric acid gas, glance coal and sulfur dioxide in purifying smoke.Wet electrical dust precipitator can also be used for the acid mist of descaling bath and processes or cock-oven gas purifying, reclaims acid solution or tar etc..
Existing wet electrical dust precipitator is in dust removal process, the throughput passed through in each anode tube is the most different, causes the throughput passed through in segment anode pipe bigger, it is impossible to fully dedusting, and the throughput passed through in another part anode tube is too small, it is impossible to give full play to efficiency of dust collection.
