Below to having the explanation that is used as according to dust collect plant of the present invention of said structure.
At first, the waste gas that produces in engineering flows into certain flow velocity by flue gas leading (102), the gas that flows into flow into earlier in the pretreatment filters (104), at this moment, because conflict, inertia, cohesion and gravity effect, there is the particle that is mixed in more than 70% in the waste gas to be captured, and is discharged in the holding vessel (108) greater than 5 μ m.
Because the foreign substances (dust, tar etc.) that has prevented to produce in the engineering in waste gas enters cylinder filter (20), has therefore prolonged the service life of filter (20).
At this moment, gas remains on 0.1m/s-3m/s by the face velocity (Face Velocity) of pretreatment filters (104), and the speed that flows into by the cylinder filter (20) that stops to the back-end, thereby plays the effect of a kind of raising filter (20) efficient.
Gas through pretreatment filters (104), flow into the inside of shell by being arranged at suction inlet (12) on the dust collect plant shell (10), be blended in particulate polluter in the waste gas this moment because the barrier effect of the cylinder filter (20) of dust collect plant, cloth youth movement effects, surface conflict effect etc., and be captured.
At this moment, waste gas is shifted to the inner process from the outside of filter (20), become gradually foreign substances by filtering clean gas, and discharge through outlet (14).Molecule through above-mentioned filter (20) filtration, capture, because the centrifugal force of the filter (20) of rotation, inner when move the outside from filter (20), since intergranular gravitation and surface tension and with other particle agglomerations, therefore more to the outside, its size and weight just increase more, thereby it is also just big more to the centrifugal force that particle rose, finally move on to the outer surface of filter (20), and since centrifugal force and breaking away from from filter (20) concentrate in the capture box (16) of dust collect plant bottom.
Observe the airtight situation between above-mentioned ring (40) and the filter bracket (24) below, as shown in Figure 4, when on discharge pipe (112), air blast (110) being set, in dust collect plant shell (10), suck waste gas, so in the inside and the outside pressure differential that produces of shell (20), shell (20) pressure inside diminishes.
Therefore, by being arranged at the discharge pipe (46) of shell (20) outside air chamber (44), air outside flows into, and through being formed at the inside of communication port (42) the inflow shell (10) on the shell (10).
So, flow out from the space between ring (40) and the filter bracket (24) with encircling between (40) by the airtight of shell (10) inside by communication port (42) leaked-in air, thus the inside of inflow shell (10).
Air between above-mentioned ring of aforesaid inflow (40) and the filter bracket (24) plays a kind of isolating valve, effect, thereby prevents that the waste gas that flow into above-mentioned suction inlet (12) from flowing into outlet (14) by the space between ring (40) and the filter bracket (24).
Therefore only discharge clean air by outlet (14).
In addition, as shown in Figure 5, if before air blast (110) is arranged at dust collect plant, thereby in the shell (10) of dust collect plant, be blown into waste gas, the discharge pipe (46) of then above-mentioned air chamber (44) is connected with the comb of above-mentioned air blast (110) entrance side, therefore can keep air-tightness.
That is, because of the discharge pipe (46) of air chamber (44) is connected with above-mentioned air blast (110) entrance side, so the air in the discharge pipe (46) is forced to suck by air blast (110).
Thereby by between above-mentioned ring (40) and the filter bracket (24) to the waste gas of outlet (14) side inflow, because the suction of the air blast (110) that is connected with discharge pipe (46), communication port (42) through shell (10) flow into air chamber (44), and owing to be sucked into air blast (110) again through discharge pipe (46), so can not flow out from above-mentioned outlet (14).
So the waste gas that is sucked again flows into shell (10) inside again through air blast (110), obtains the filtration of cylinder filter (20).
At this, the air capacity that the communication port (42) through above-mentioned shell (10) circulates or drops into accounts for the 1%-20% of total exhausted air quantity that overall cylindrical filter (20) handles.
As mentioned above, under the airtight situation that is not adjacent to ring (40) of filter bracket (24) and shell (10), also can make it keep air-tightness, thereby can make cylinder filter (20) from tens of rev/mins, to thousands of rev/mins, and can prevent owing to rotating the device damage that takes place at a high speed.
In addition, as shown in Figure 8, when the flange (28) on being arranged at filter bracket (24) was given prominence to by the communication port (42) of shell (10), the waste gas that flows in the shell (10) by suction inlet (12) was blocked because of flange (28), thereby can not flow into the discharge oral-lateral.In addition, air chamber (44) is identical with foregoing explanation with the function of discharge pipe (46).
Being discharged to the outside dust of filter (20) become trapped in the capture box (16) of shell (10) bottom surface, and drain into by discharge pipe (18) in the holding vessel (108) of outside, the condensate liquid that is discharged from is used on the engineering again, handles air clean and then be discharged to the outside of dust collect plant by this gas processing device.
In cylinder filter of the present invention (20), because the particulate contaminants matter that flows into is many more, also many more with the cohesion amount of other particles, it is big that particle becomes, thereby centrifugal force also increases, so the disengaging amount from filter (20) also increases, under the opposite situation, because centrifugal force is little, the amount that breaks away from from filter (20) also reduces, so always contain a certain amount of particulate contaminants matter after filtering, even change the granule density in the inflow gas treatment facility, also can keep stable function, so can carry out stable operation.
Fig. 9 and Figure 10 are that expression is according to the efficient and the comparison chart of keeping warranty charges of dust collect plant of the present invention with the past device.
Numerical value in the above-mentioned chart utilizes normally used particle collector (Particle Counter) (manufacturer: record Ltechinstrument company).
Fig. 9 is that expression utilizes according to the dust collect plant of revolving filter of the present invention and the dust catching efficiency comparison chart of electrostatic (electric dust) precipitator, candle filter dust arrester and the demister dust arrester of past dust collect plant, can find out from chart, centrifugal dust collect plant according to the present invention is all high than imitating to the dust catching efficiency of different-grain diameter, and particle diameter also is captured more than 80% greater than the particle of 0.2 μ m.
Figure 10 is that expression utilizes output investment ratio according to the dust collect plant of revolving filter of the present invention and other devices in the past, area is set and keeps the comparison chart of warranty charges year, can find out from chart, output investment ratio only is 1/5 of past equipment, area is set only accounts for over the 1/3-1/5 of equipment, keep guarantee expense and demister dust arrester quite or be about 1/2.
As mentioned above, according to dust collect plant of the present invention, compare its handle with the gas processing device in past Various physical property principles integrally have been combined in the equipment, by continuous discharge filter capture small Particle can make the filtration flow-rate of filter minimize, and can make the arresting efficiency maximization of filter, So compare with the gas processing device in past, setup fee and area is set can reduces more than 70%, And can make the minimise loss of pressure for the treatment of facility, therefore have the effect of save operation and expenditure on power.
In addition, keep air-tightness by making between filter and shell with cordless, make filter at a high speed Rotation, thus the discharge ability of molecule improved, and owing to prevented because of high-speed rotary then make gas Therefore the wearing and tearing of compact part spare can semi-permanent use filter, therefore has the guarantee expense of keeping of saving Effect.
