Description

Filter cylinder in-line arrangement module combinations cycle pulse ash cleaning and dust removing device

The utility model be a kind of be the deduster that module combinations is got up with the cartridge filter in-line combination with basic dust removing units.

In exhaust gas treatment technology, adopt the deduster of filtering technique, at present at home, external application get at most be sack cleaner.Though do not seen the introduction of filter drum type precipitator in " three wastes are handled Technical Manual-Engineering waste gas volume " lining that publish in October, 98, begun to have the appearance of filter drum type precipitator abroad in 83 years.Filter drum type precipitator is the new generation product of sack cleaner, and its main feature is that the filter bag of the identical filter area of the shared volume ratio of the filter cylinder of identical filter area wants little 5 to 30 times.Therefore under the condition of identical filter area, the shared volume of filter drum type precipitator is little more many than sack cleaner.At home, existing at present heavy streaming filter cylinder inclined type deduster, filter cartridge type miniature single-machine deduster.Filter cylinder is tilting outside filtering type deduster, its filter cylinder center line becomes 15 degree angles approximately with horizontal plane, though the dust direction that sinks is consistent with the dust-contained airflow direction that enters during deashing, can be fallen into ash bucket with air-flow by the dust under clear on the filter cylinder, but because filter cylinder is folding, dust in the groove of the filter cylinder first half 1/3rd peripheries is difficult to clear clean, the part dust that is cleared simultaneously can fall back again in the groove of the filter cylinder first half, therefore clear dirt is not thorough, effective filtration area lacks than design area, and filtration resistance increases.Filter cartridge type miniature single-machine deduster is to collect filter cylinder, soot cleaning system, blower fan, automatically controlled, ash bin in a deduster, be similar to a large refrigerator, the filter area of this deduster has specifications such as 12,18,27,40,54 square metres, handles air quantity at 2000--10000m ³/ h.The deduster 1 of this structure is suitable for making processing air quantity 10000m ³The large and medium-sized deduster that/h is above.

Traditional pocket type or filter drum type precipitator are difficult in use find which group or which filter have leakage phenomenon, therefore the user often incurs loss through delay the time of changing filter and causes to discharge and exceed standard, after often delaying the discharging severe overweight, all take out and check or whole the replacing.

The task of the utility model deduster is to be filtering material with the filter cylinder that chemical synthetic material is made, and designs a kind of deduster that can reach following function:

1. in identical filter area or handle the deduster of identical dusty gas, shared volume is little;

2. manufacturing process is simple, and cost is low;

3. the filter deashing is thorough;

4. efficiency of dust collection height;

5. long service life;

6. the filter cylinder of wear and leakage in time finding to use, the maintain and replace filter is convenient;

7. can be combined into the deduster of any size, maximum can be combined into the deduster of per hour handling the above dusty gas of air quantity 100 ten thousand steres.

In order to achieve the above object and function, the utility model is designed to as shown in drawings " filter cylinder in-line arrangement module combinations cycle pulse ash cleaning and dust removing device ".This deduster vertically can build up several layers, laterally can line up any ordered series of numbers, except that being arranged in a row, also can line up double or number row.Therefore maximum can be combined into the deduster of per hour handling the above dusty gas of 100 ten thousand steres.

By accompanying drawing as can be known " filter cylinder in-line arrangement module combinations cycle pulse ash cleaning and dust removing device " form by air inlet [1], exhaust outlet [2], perspective window [3], soot cleaning system [4], front and back access door [5], ash bucket [6], bearing support [7], basic dust removing units [8], auger conveyor [9], dust block board [10], inlet channel [11], combination filter cylinder [12], deashing nozzle [13], peace and quiet air chamber parts such as [14].

The operation principle of this deduster is: dust-contained airflow enters deduster from air inlet [1], arrive the deduster bottom rapidly by inlet channel [11], upward (function of dust block board is only to allow dust to fall into ash bucket to impact the dust block board [10] that is located at above the ash bucket [6], and the dust from flying that stops ash bucket [6] lining comes out), turning back is filled to each space in the deduster again.Owing to gas shock, turn back, change reasons such as direction, the dust that most of particle is bigger in the air-flow is under the effect of gravity and inertia force, fall into ash bucket, more fine grain dust is blocked in the outside of combination filter cylinder [12] with air-flow, peace and quiet gas enters the inside of combination filter cylinder [12], enter peace and quiet air chamber [14] again,, be inhaled into centrifugal blower and enter chimney or atmosphere by exhaust outlet [2].Soot cleaning system [4] and deashing nozzle [13] (belong to electric-controlled parts by pulse control instrument or computer, demonstration among the figure) control realizes automatic cycle pulse deashing to the dust that combination filter cylinder [12] outer surface gathers, dust is shaken off ash bucket [6] lining, and the dust of long-pending full some is discharged by auger conveyor [9].

As previously mentioned, the utility model deduster is to be formed for module combinations by basic dust removing units [8].In basic dust removing units [8] lining the cartridge filter made from synthetic material is housed in upright arrangemently, and connects into combination filter cylinder [12] with the mechanical connection method.Because filter cylinder is with the wide folding tubular of making of synthetic material, concentrate in the less space the filter area of filtrate is folding, combination filter cylinder [12] is contained in the deduster in upright arrangemently, so under identical filter area condition, the shared volume ratio filter bag of in-line combination filter cylinder wants little 5-30 doubly.For example: the combination filter cylinder bulk that the cartridge filter of three φ 350X660mm is formed is φ 350X2010mm, and its filter area is 32.7m ², and the filter bag of three φ 300X10000mm, its filter area only is 28.3m ²Therefore under identical filter area condition, the shared volume ratio sack cleaner of filter cylinder in-line arrangement module combinations deduster is much smaller, and the steel of the manufacturing deduster that brings therefrom will lack, and manufacturing cost just can be lower than sack cleaner.

Intake method is used by the utility model deduster system, dust-contained airflow impacts on the dust block board [10] from top to bottom, the combination of flow of turning back again filter cylinder [12], big dust particle falls into ash bucket in the effect of gravity, inertia force, more fine grain dust is filtered by combination filter cylinder [12], therefore this deduster dust removal mechanism is filtration, gravity, three kinds of effects of inertia force dedusting, can filter the dust of high concentration.

The front and back of the basic dust removing units of each of the utility model deduster [8] all are provided with access door [5], open access door, with regard to replaceable cartridge.

The front and back of the utility model deduster peace and quiet air chamber [14] on top all are provided with perspective window [3], and wearing and tearing in time finding to use, the filter that leaks are convenient in time change filter cylinder.

The utility model deduster adopts known high strength overlay film polyester filter cylinder and cycle pulse ash-clearing technology, makes the deduster deashing thorough, and equipment resistance is low, long service life, and efficiency of dust collection can be up to 99.9---99.99%.

The utility model deduster adopts well-known deduster manufacturing technology just can create, and need not just can produce large-scale dedusting unit by large-scale manufacturing equipment.
