Abstract
The utility model discloses an electric-bag composite type dust collector, which includes an electric dust collecting device and a bag type dust collecting device, wherein a front sealing head is arranged at the front end of the electric dust collecting device and the bag type dust collecting device is arranged at the rear end of the electric dust collecting device; ash buckets are arranged at the lower parts of the electric dust collecting device and the bag type dust collecting device respectively; the bag type dust collecting device includes at least two filtration chambers arranged at the same height; and a flow preventing device is arranged between the two adjacent filtration chambers. Through the flow preventing device arranged between the two adjacent filtration chambers, the dust collector can eliminate local high-speed airflow in the bag type dust collecting zone, thereby improving the dust collection effect; in the structure which adopts the flow preventing device, a flow guide device and a flow distributing device can be eliminated on the basis of retaining a large-scale dust collector, so that the cost is reduced; and furthermore, the filtration chambers are arranged at the same height and share one air purifying chamber, the structure is simpler and the cost is lower.
Description
[technical field]
The utility model relates to environmental protection equipment, relates in particular to a kind of electric-bag complex type dust remover.
[background technology]
About 70% of China's soot emissions total amount derives from the burning of coal, and discharging a large amount of minuteness particle in coal-burning power plant's is main particle pollution sources.Electric cleaner and sack cleaner are the most frequently used cleaners in coal-burning power plant.
Advantages such as it is big that electric cleaner has the smoke treatment amount, and equipment resistance is low.But its efficiency of dust collection is subjected to the influence of dust characteristic bigger, to the flue dust of some high specific resistances, reach very difficulty of the existing environmental standard of China.
Sack cleaner is a kind of filtering type cleaner.Shortcomings such as its outstanding advantage is that efficiency of dust collection is high and stable, but has the SR height, and life of bag filter is short.
The front portion of electric-bag complex dust collector is the electric precipitation district, and the rear portion is the bag dedusting area.Electric-bag complex dust collector at first utilizes electrostatic precipitation to remove most of flue dust, utilizes bag-type dusting to capture remaining dust in the flue gas again, to reach the purpose of high-efficiency low-resistance.Electric-bag complex dust collector has very strong adaptability.Especially in the occasion of existing electric cleaner transformation, advantage is more outstanding.
But, there is local high velocity air between the adjacent filter bag of present common electrical bag complex type dust remover, influenced dust removing effects.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of electric-bag complex type dust remover, can eliminate the local high velocity air between the adjacent filter bag, improves dust removing effects.
For achieving the above object, the utility model proposes a kind of electric-bag complex type dust remover, comprise electric dust collector, exhaust dust device with bag, the front end of described electric dust collector has front head, the rear end is an exhaust dust device with bag, the bottom of electric precipitation district and bag dedusting area is provided with ash bucket, and described exhaust dust device with bag comprises the filter chamber that at least two co-altitudes are provided with, and is provided with choke apparatus between two adjacent filter chambers.
As preferably, be provided with guiding device between described electric dust collector and the exhaust dust device with bag.
As preferably, be provided with the air-flow current equalizer between described electric dust collector and the front head.
As preferably, described choke apparatus is a perforated plate construction, and the diameter in hole is 110mm-130mm, and porous plate is arranged near the position filter bag bottom of filter chamber.
The beneficial effects of the utility model: the utility model is by installing choke apparatus to eliminate the local high velocity air in the bag dedusting area between two adjacent filter chambers, improved dust removing effects, this structure is after adopting choke apparatus, except that large-scale deduster, can cancel guiding device and current equalizer, reduce cost.And filter chamber is arranged on identical height, can a shared air-purifying chamber, and structure is simpler, and cost is lower.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the structural representation of a kind of electric-bag complex type dust remover of the utility model.
[specific embodiment]
As shown in Figure 1, a kind of electric-bag complex type dust remover comprises electric dust collector 3, exhaust dust device with bag 5, the front end of described electric dust collector 3 has front head 1, the rear end is an exhaust dust device with bag 5, the bottom of electric precipitation district and bag dedusting area is provided with ash bucket 7, described exhaust dust device with bag 5 comprises between 6, two adjacent filter chambers 6 of filter chamber that two co-altitudes are provided be provided with choke apparatus 9 at least.Be provided with guiding device 4 between described electric dust collector 3 and the exhaust dust device with bag 5, be provided with air-flow current equalizer 2 between described electric dust collector 3 and the front head 1, further improve dust removing effects.Described choke apparatus 9 is a perforated plate construction, and the diameter in hole is 110mm-130mm, and porous plate is arranged near the position, filter bag bottom of filter chamber 6, and this aperture air feed stream is better passed through.Above-mentioned dust arrester 3, exhaust dust device with bag 5 and ash bucket 7 are installed on the housing 8.Because filter chamber 6 is arranged on identical height, therefore can a shared air-purifying chamber 10, structure is simpler, and cost is lower.
Ash-laden gas at first captures most of dust by the electric precipitation mode, then captures remaining dust by the filter bag filter type.The flowing through channel of dusty gas in deduster is: front head 1 → air-flow current equalizer 2 → electric dust collector 3 → guiding device 4 → exhaust dust device with bag 5 → air-purifying chamber 10.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
