Abstract
The invention discloses a dust catcher, which comprises a dust cell, an exhaust column arranged on the dust cell, an air inlet and an ash hopper. At least a filtering screen unit is arranged in the dust cell, which comprises a filtering screen drive device, a sealing component is arranged at the two sides on and down the filtering screen drive device, the filtering screen covers on the drive device and the sealing component and forms a sealing filtering screen unit inner cavity, a soot cleaning device is arranged at a soot cleaning zone close to the filtering screen at one side of the filtering screen unit inner cavity, at least a connection opening which makes the filtering screen unit inner cavity connected with the exhaust column is arranged on the sealing component. The invention can realize continuous exhausting, dedusting and soot cleaning, and overcomes the defects that the existing dust catcher only can dedust fixedly, work and dedust intermittentedly brings increased dedusting load and lower dedusting capability, which has the advantages of high dedusting efficiency, less equipment investment, low running cost and convenient maintenance.
Description
Technical field
The invention belongs to cleaner, be specifically related to a kind of deduster that adopts the filter cloth dedusting.
Background technology
The great advantage of sack cleaner is exactly the efficiency of dust collection height.Last century five, the sixties, sack cleaner is the capital equipment of China's industrial dedusting, and to last century seven, 80 years, people introduced electrostatic precipitator, and sack cleaner was once once replaced by electrostatic precipitator.In recent years, owing to improving constantly of waste gas emission standard, sack cleaner is subjected to people's favor once more, and use occasion is more and more.Because the sack cleaner its specific structure makes sack cleaner exist unsurmountable defective, the shortcoming of sack cleaner is as follows.1, damaged filter bag can't be checked, needing to cause regular integral replacing filter bag.Sack cleaner is made up of hundreds and thousands of filter bags, in the course of work, be subjected to external influence, filter bag at any time might be damaged, because the space is very little between filter bag and the filter bag, the maintainer can't enter dirt pocket and check damaged filter bag, and damaged filter bag such as untimely eliminating will reduce efficiency of dust collection, so sack cleaner middle and later periods efficiency of dust collection descends.General way is all filter bags of periodic replacement, wastes bigger; 2, cause the secondary dust during deashing: sack cleaner generally adopts the backblowing deashing, directly dust stratification is blown into dirt pocket, causes secondary fly-up; 3, the equipment waste is big, the operating cost height: adopt the sack cleaner of backblowing deashing, the filter bag that is under the deashing state does not participate in dedusting, has reduced the complete machine dust collection capacity of deduster, also in dirt pocket, be blown into a large amount of air simultaneously, increase the load of deduster.Guarantee the dust removing effects of deduster under the deashing state, certainly will will increase dust collection capacity, increased equipment investment, improved operating cost.
Summary of the invention
The objective of the invention is to overcome the shortcoming of existing sack cleaner, but a kind of continuous operation is provided, dynamic deashing, the deduster that efficiency of dust collection is high.
The present invention seeks to be achieved through the following technical solutions:
Deduster of the present invention comprises dirt pocket, be located at the exhaust column on the dirt pocket, air inlet, ash bucket, in dirt pocket, be provided with a filter curtain unit at least, a described filter curtain unit comprises and being arranged on the dirt pocket by driving shaft, the filter curtain drive unit that driving wheel and driven pulley are formed, both sides up and down at drive unit are provided with seal member, on filter curtain drive unit and seal member, be coated with the filter curtain unit inner chamber of filtering curtain and forming sealing, inner chamber one side is provided with deashing device near the deashing district of filtering curtain in filter curtain unit, is provided with a connector that filter curtain unit inner chamber is linked to each other with exhaust column on the seal member at least.
Further technical scheme also comprises:
In the described dirt pocket, filter curtain unit combination becomes series unit, and a connector on one of them filter curtain unit links to each other with exhaust column, is communicated with by other connector between each filter curtain unit inner chamber;
In the described dirt pocket, the series unit that described filter curtain unit combination becomes is several.
When deduster of the present invention is worked, be divided into the dedusting area and filter act deashing district of filter curtain translation section in the dirt pocket around the deashing device meander sections.Filter curtain drive unit drives driving wheel by driving shaft and rotates, and driving wheel drives the motion of filter curtain.Meanwhile, because the draft effect of exhaust column, dusty gas by the dedusting area in the air inlet inlet chamber of dirt pocket, enter filter curtain unit inner chamber from the outside, filter curtain unit by the filter curtain, because the filtration of filter curtain, dust in air constantly is deposited on the outer surface of filter curtain.When filter curtain ran to the deashing district, deashing device outwards sprayed high-voltage pulse gas, and under the purging of high-pressure jet, the dust stratification that is deposited on filter curtain outer surface is blown off and crashes into ash bucket, finishes a removing dust and clearing ash process.Filter curtain behind the deashing enters next removing dust and clearing ash circulation once more.Purified gas then enters atmosphere by exhaust tube, thereby reaches the purpose of dedusting.Dirt pocket can be provided with the quantity and the mode of filter curtain unit combination according to the needs that remove dust quantity.
Deduster of the present invention can be realized serialization ventilation and dust removal and deashing owing to adopted rotary filter curtain unit in dirt pocket, has overcome the fixedly dedusting of filter bag of existing sack cleaner fully, the shortcoming that service intermittent and deashing brought.Have the following advantages:
But 1, deduster continuous motion does not need to shut down deashing, has improved efficiency of dust collection;
2, separating of dedusting area and deashing district, overcome the shortcoming that causes secondary fly-up during the sack cleaner deashing;
3, the filtrate of deduster of the present invention is running continuously, and deashing and dedusting are carried out simultaneously, are independent of each other;
4, equipment investment is few, operating cost is low: deduster deashing action of the present invention is continuous, neither influence dedusting during the deashing, do not increase load of dust remove yet, need not increase the dust collection capacity of deduster for deashing, compare, reduce specification of equipment with sack cleaner, reduce equipment investment, saved operating cost;
5, easy access: sack cleaner is owing to the reason in place, can't find when filtrate is damaged, more can't overhaul, deduster of the present invention is because the filter curtain is in continuous operating condition, the maintainer stands in the intact situation that same position just can be observed whole filter curtain, the discovery breakage can be repaired at any time, guarantees the performance of deduster for a long time.
Further specify technical scheme of the present invention below in conjunction with accompanying drawing.
