Description
Technical field:
The utility model relates to a kind of through electric-bag complex dust collector, is used to administer pollution that flue gas and dust cause and to the recovery of dust.
Technical background:
At present known electric-bag complex dust collector generally all is electric cleaner and sack cleaner to be cascaded combine, but this combination can not be given full play to the advantage separately of electric precipitation and bag-type dust, causes the amplitude bulky, that resistance increases, efficiency of dust collection improves of deduster limited.The utility model is comprehensive utilization and the advantage that organically combines electric precipitation and bag-type dust, capture a large amount of big dust particle in flue gas and the dusty gas by the electric precipitation chamber earlier, can collect in flue gas and the dusty gas about 80% Dust Capacity, collect remaining particle diameter trickle dust between 0.2～0.5 μ m in conjunction with latter's bag-type dust chamber again, be a kind of combination high-efficiency deduster, have characteristics such as efficiency of dust collection height, dust collection capacity is stable, volume is little, resistance is low.
Summary of the invention:
A kind of through electric-bag complex dust collector of the utility model has mainly been taked following technical measures:
1,, helps applying unit existing deduster is transformed, electric back pkt. and through version before this deduster is taked in order to reduce the deduster floor space.
2, in order to reduce the resistance of deduster, the electric precipitation chamber is combined with the bag-type dust chamber is organic, the joint portion is through transition chamber, and airflow fence and deep bead are set, and airflow fence is an airfoil type.The gas that the electric precipitation chamber is ejected can enter the bag-type dust chamber smooth and easy, uniformly from the bottom, can make the load of dust remove of each cloth bag average as far as possible again, and dust flows backwards and enters the electric precipitation chamber once more can effectively prevent the cloth bag deashing time, thereby avoided the reentrainment of dust of electric precipitation chamber.
3, in order to improve the efficiency of dust collection of deduster, electric precipitation chamber and bag-type dust chamber are taked following structure respectively:
1. the airflow-distribution board of shutter and suitable percent opening is set at the electric precipitation chamber inlet place of deduster, shutter is made downward-sloping 45 degree plank frames, the airflow-distribution board percent opening is 75%, wherein big heavier particle falls into dust collector ash hopper in the effect of shutter when not only making dusty gas enter the electric precipitation chamber, and makes dust-contained airflow obtain slowing down, spread and evenly distribute.
2. in order to make grit obtain fully charged and rational field gas velocity in the electric precipitation chamber, corona discharge electrode adopts barbed nail corona electrode, and the collecting electrode plate adopts the S type.Prickle wire replaces discharging along the polar curve total length with point discharge, its strength of discharge height, discharge inception voltage are hanged down also can strengthen electric wind, and can weaken and prevent to occur the corona blocking phenomenon when dust concentration is big, be suitable for purifying the dusty gas that dust content is higher, dust specific resistance is high.S type collecting electrode plate can make that its lip-deep electric field CURRENT DISTRIBUTION is even, sparking voltage is high, helps dust and deposits on the plate face and can fall into ash bucket smoothly, and reentrainment of dust is few, has good rapping simultaneously, is easy to deashing, and good rigidity, and is not yielding.Thereby the field gas velocity of determining the electric precipitation chamber is 0.8～1.2 meter per second, velocity of approach 0.07～0.1 meter per second of grit in the gas, and the height/width ratio of collecting plate is 1.2.
3. for the bag-type dust chamber at rear portion, adopt pulse backblowing circle cloth bag vertical structure, because most of dust has been caught by the electric precipitation chamber and has been disposed, only surplus a spot of fine dust enters the bag-type dust chamber and powder dust particle still has a little charge, the seizure dust ability and the deashing that more help cloth bag, can make the filtration velocity of cloth bag reach 3～3.5 meters/minute, and cleaning cycle is prolonged, realize handling cloth bag quantity minimizing under the same air quantity condition, the reduction of deashing number of times, reduced volume, prolonged the cloth bag purpose in service life.
4, in order to guarantee the effective deashing of deduster, the vibration dust-cleaning mode is adopted in the electric precipitation chamber, and top discharge electrode vibration dust-cleaning mechanism and bottom dust collecting electrode vibration dust-cleaning mechanism are set, and replaces sub-room cleaning according to the cycle of setting during operation.Pulse jetting deashing mechanism is adopted in the bag-type dust chamber, and the pressure reduction locellus when moving according to the bag-type dust chamber carries out deashing.The frequency of the pulse jetting deashing of the vibration dust-cleaning of electric precipitation chamber and bag-type dust chamber, duration unification are controlled by the electric control gear of deduster.
The beneficial effects of the utility model are, the volume of deduster reduces, realized the combination of electric precipitation and bag-type dust, given full play to both separately advantage and realized mutual supplement with each other's advantages, the resistance of deduster is 900～1100Pa, efficiency of dust collection reaches more than 99.9%, and is better to the dust removing effects of fine dust especially, has that resistance is low, efficient is high, satisfy effects such as high standard discharging.
