Description
The dust collect plant that the present invention relates to is that dusty gas (dusty gas) formation that dust content concentration is big utilizes the reverse vortex of centrifugal force and makes it mobile, so that greatly increase the dust collect plant of dust collection capacity and efficiency of dust collection.
Past, the form of typical dust collect plant is to import dusty gas to the dusty gas inflow entrance that is positioned at the device bottom, by being configured in the filter of device inside, after while flowing dust being filtered, be filtered the dust of separating, fall and accumulate to the dust outlet that is positioned at the device bottom by gravity, outside the switching discharger by discharge valve.The clean filtered air of making by filter then is drawn out of by the filtered air outlet on device top.
Yet, the dust collect plant of passing by like this, if when flowing into the big dusty gas of dust content concentration, then the load of dust remove that bears of filter strengthens, the compacted massively direct contacted filter of rigidity dust surface, filter can be worn away inevitably, when if the dusty gas temperature that flows into is high, then damage easily with the filter that such high temperature dust gas directly contacts, filter life is shortened, therefore reduced the performance of dust collect plant, can produce and to bring into play due dust collection capacity, sharply reduce problems such as efficiency of dust collection.
Recently, for addressing the above problem, a kind of separate type dust collect plant scheme is proposed.Promptly shown in the 4th figure, the dust collect plant separation is set to centrifugal cyclone formula dust collect plant (A) and filter filters formula dust collect plant (B), earlier in centrifugal cyclone formula dust collect plant (A), the dusty gas that contains the rigidity dust that dust content concentration is big, carry out one-time dedusting by utilizing centrifugal force rotational flow gravity to fall the aggregation mode, because the effect dust content concentration of one-time dedusting diminishes, the dusty gas that secondly will contain the floatability fine dust imports filter from centrifugal cyclone formula dust collect plant (A) and filters formula dust collect plant (B), carries out last filtration at filter (C) and finishes the dedusting effect.
Yet, such separate type dust collect plant, have again that unit scale is huge must to guarantee enough spaces that is provided with, and shortcoming economically such as manufacturing expense rising, key issue has also caused too much power consumption because of the pressure loss that takes place as the centrifugal cyclone formula dust collect plant (A) of one-time dedusting device and the pressure loss that takes place from the filter type dust collect plant (B) of final dusting device when it move, thus have energy loss excessive with install shortcoming such as running expense rising.
The Japanese publication relevant with the present invention announced clear 49-13969 number and disclosed a kind of dust collect plant, it is in the tapered rotating filter indoor of rounding dividing plate to be set and air-flow is induced pipe, on dividing plate top the 2nd filtering bodies is set, make the dusty gas rotational flow that is directed in dusty gas rotating flow inlet, dust is along the dust stacking part of accumulating after the inwall that rotates through filter chamber is passed by on one's way by air communication in ring-type, just being induced the central portion of pipe to flow along air-flow with cyclone mode by the dusty gas of one-time dedusting like this rises, passes through then with the net hair, urethane foam sponge or carry out final dedusting with the 2nd filtering bodies that fibrous material is made.This device is after dusty gas is carried out one-time dedusting with cyclone mode, to make it by the 2nd filtering bodies again, avoids making the 2nd filtering bodies to bear excessive load as before.But because the surface of the 2nd filtering bodies that directly contacts with dusty gas is a horizontal plane, the surface area that contacts with dusty gas is defined very narrowly, so be difficult to obtain high efficiency dust removing effects.And owing to can adhere to a lot of dust in the short time on the narrow surface of the 2nd filtering bodies, cause the gas that is filtered by the time bear too much load, so just can not give full play to the filtration function; Along with bearing overload, the also too much power of inevitable requirement, this just still has causes the shortcoming that fatal energy loss and dedusting function sharply reduce.
Japanese Utility Model is open have been disclosed for the clear 61-33625 of communique number and a kind ofly to be equipped with air intake duct in central authorities of cyclone body epimere portion.In cyclone body epimere portion side, be formed on the dusty gas inflow entrance that imports outside dusty gas on the cyclone body inwall tangential direction, make the dusty gas that imports by dusty gas inflow entrance rotational flow in the inwall of cyclone body and the zone between the air intake duct, then the dust of the rigidity that particle is big drops on cyclone bottom aggregation, then is inhaled into the dust collect plant that air intake duct is discharged again through the dusty gas of 1 remaining fine dust of dedusting.Yet this device is to make dusty gas rotational flow between the inwall of cyclone body and the air intake duct, only have the dusty gas that to contain bulky grain rigidity dust and carry out dedusting, promptly finish the structure of dedusting effect, so the dusty gas that contains remaining fine dust is not carried out final dedusting, and intactly discharge to the outside, so the shortcoming that can not get perfect dust removing effects is arranged.
The objective of the invention is provides a kind of improved dust collect plant that can easily handle any form dust in order to solve problem and the shortcoming on the above-mentioned existing dust collect plant.No matter be that dust concentration is high or contain the dusty gas that the rigidity dust can make the filter abrasion, and after high temperature or the dusty gas that contains moisture flow into this device, because these dusty gas directly do not contact with filter, therefore do not increase undue load to filter, can prevent abrasion, prolong the service life of filter.When high temperature dust gas flowed into, owing to the reduced space portion one side rotational flow of dusty gas at the rotational flow air-flow, a surface temperature was lowered, thereby has prevented the damage of filter, has promoted the performance and the efficiency of dust collection of dust collect plant.
Another object of the present invention provides a kind of dust collect plant with energy-saving effect.The contact surface of this device middle filtrator is long-pending big, not only can access high dust removal performance and efficient when carrying out the dedusting operation for a long time, and because the contact area serious offense filter of dust does not bear overload, so do not use too much power.
A further object of the invention provides a kind of dust collect plant of good economy performance, the cost of equipment that the per unit of this device is handled the dusty gas air quantity is lower than existing dust collect plant price, and simple structure, can in less area of space, be provided with, because change filter and keep in repair easy, so good economy performance.
