Abstract
The invention relates to a flue gas purification deduster. The flue gas purification deduster is characterized in that the upper part of a deduster housing is a demisting zone, the middle part of the deduster housing is a dust collection zone, the lower part of the deduster housing is a charged zone, the top of the deduster housing is provided with an air outlet, the bottom of the deduster housing is provided with an ash bucket, a corona pin of an ion nozzle fixed to a resin helix tube is connected to a negative pole of a high voltage power supply, nozzles are uniformly distributed around a circular water pipe in the dust collection zone along a peripheral direction, an air feeding pipe is connected to a circular air pipe, a water feeding pipe is connected to the circular water pipe, an outlet head of the circular air pipe is connected to a two-phase nozzle gas phase joint on the circular water pipe, water from the water feeding pipe is connected to a ground terminal of the high voltage power supply, a water curtain and water mist are arranged in the dust collection zone, the water curtain is an induction charged water curtain and external voltage is directly applied for an induction coil. The flue gas purification deduster has a simple structure, a small equipment investment, a low cost and a small land occupation area and treats fine, large-viscosity and wet dust and combustible flue gas-containing explosive gas in a blast furnace and a converter.
Description
Technical field
The invention belongs to environmental conservation gas cleaning cleaner, particularly to a kind of gas-cleaning duster.
Background technology
At present, domestic conventionally employed electrostatic precipitator in the improvement of dust pollution, although it has efficiency of dust collection height, dedusting internal resistance is little, it is low to consume energy, it is big to process flue gas capacity, trapping dust is dry non-secondary pollution, it is readily transported and the advantage such as utilization, but exist: device structure is complicated, bulky, cost is high, invest big problem, in use viscous, wet, thin dust can not be processed；The gas cleaning difficulty processed containing imflammable gas is very big, there are the problems such as explosion danger.
Summary of the invention
Instant invention overcomes the defect of above-mentioned existence, it is therefore an objective to gas cleaning cleaner structure is complicated, bulky, cost is high, investment is big in order to solve, in use viscous, wet, thin dust can not be processed；Very big to processing gas cleaning difficulty containing imflammable gas, have the problems such as explosion danger, it is provided that a kind of simple in construction, volume are little, dust-collecting efficiency is high, gas-cleaning duster.
Gas-cleaning duster content Description of the present invention:
Gas-cleaning duster of the present invention, it is characterised in that: the top of shell of dust remover be except fog-zone, middle part are dust collection section, bottom be charging area, shell of dust remover top be air outlet, bottom be ash bucket；The corona pin of the ion nozzle being fixed on resin serpentine pipe is connected with the negative pole of high voltage power supply；Annular water pipe in dust collection section is circumferentially evenly arranged nozzle, it is connected with annular airduct for airduct, feed pipe is connected with annular water pipe, airduct is lifted one's head and is connected with the two-phase formula nozzle gas phase joint on annular water pipe, water for feed pipe is connected with high voltage power supply earth terminal, water curtain and water smoke are set in dust collection section, adopt induc-tion charging method water curtain, applied voltage is applied directly on induction coil, two-phase formula nozzle is arranged on induction coil center, when water is by high-tension coil, water curtain can be charged, and charged polarity is contrary with applied voltage.
Gas-cleaning duster of the present invention, simple in construction, only with an electric field, a high voltage power supply and a control system, Wet-type spray dedusting and electrostatic precipitation are merged.Cathode line and cathode rapping system is not had in equipment, also without positive plate and anode rapping system, equipment investment is little, cost is low, take up an area less, can to not only wet but also thin dust tiny, that viscosity is big, have the gas of explosion danger to process containing flammable flue gas blast furnace, converter etc., efficiency of dust collection is high, applied widely.
Detailed description of the invention
Gas-cleaning duster of the present invention is achieved in that and illustrates below.
The top of shell of dust remover be except fog-zone, middle part are dust collection section, bottom be charging area, shell of dust remover top be air outlet, bottom be ash bucket；The corona pin of the ion nozzle being fixed on resin serpentine pipe is connected with the negative pole of high voltage power supply；Annular water pipe in dust collection section is circumferentially evenly arranged nozzle, it is connected with annular airduct for airduct, feed pipe is connected with annular water pipe, airduct is lifted one's head and is connected with the two-phase formula nozzle gas phase joint on annular water pipe, water for feed pipe is connected with high voltage power supply earth terminal, water curtain and water smoke are set in dust collection section, adopt induc-tion charging method water curtain, applied voltage is applied directly on induction coil, two-phase formula nozzle is arranged on induction coil center, when water is by high-tension coil, water curtain can be charged, and charged polarity is contrary with applied voltage.
Gas-cleaning duster of the present invention, arranges three road water curtains, twice water smoke altogether in dust collection section, and its efficiency of dust collection is up to more than 99%.Flue gas after purification enters air outlet after venetian blind type demister is except mist, enters air through air-introduced machine.
Gas-cleaning duster of the present invention, simple in construction, adopt an electric field, a high voltage power supply and a control system, Wet-type spray dedusting and electrostatic precipitation are merged.Not having cathode line and cathode rapping system in equipment, also without positive plate and anode rapping system, equipment investment is little, cost is low, occupation of land is few.
Gas-cleaning duster corona discharge of the present invention is to carry out in the ion nozzle of cleaning, not by the impact of smoke property, can to not only wet but also thin dust tiny, that viscosity is big, have the gas of explosion danger to process containing flammable flue gas blast furnace, converter etc., efficiency of dust collection is high, applied widely.
