Description

The packed tower of air cleaning

Technical field

The present invention relates to the technical field of filler tower, a kind of specifically packed tower of air cleaning.

Background technique

Packed tower is one kind of tower, interior to be equipped with packing layer, is equipped with corresponding filling block in packing layer, passes through filler Block increases by two kinds of contact surfaces between gas and liquid, and liquid flows from top to down to be declined along filler layer surface, gas then from Under be up filled with and contact with each other and act on liquid, since such filler tower structure is simpler, overhaul more convenient, be widely used in The operations such as gas absorption, distillation, extraction.But in the actual application of this existing packed tower, exhaust gas often contains very Mostly subtle impurity particle or waste residue is liable to stick on the interior wall in packing layer hole during carrying out waste gas absorption, so that filling out Wall is easy fouling in bed of material hole, reduces packed tower exhaust treatment efficiency, also needs often to replace packing layer.

Summary of the invention

The present invention is directed to solve at least some of the technical problems in related technologies: it is net to provide a kind of air The packed tower of change, exhaust-gas treatment effect is good, and packing layer frequency of maintenance is low.

For this purpose, it includes with inner cavity an object of the present invention is to provide a kind of packed tower of air cleaning Cylinder, the cylinder is interior to be equipped with packing layer, and described filler layer separates the cylinder into upper chamber and lower chambers, the side wall of the cylinder It is equipped with the air inlet pipe being connected to for the lower chambers with cylinder, the top of the cylinder is equipped with the exhaust outlet being connected to upper chamber, The spray system towards packing layer position ejecting liquid is equipped in the upper chamber, it is characterised in that: the packing layer Including filler supporting plate, filler supporting plate is equipped with several through-holes for being used to be connected to upper chamber and lower chambers, is equipped with and fills out in each through-hole Expect block, the position that filler supporting plate is corresponded on the inner sidewall of the cylinder is equipped with an annular slot, the outer rim of the filler supporting plate It is assemblied in annular slot, and surrounds to form an annular and touch between the lateral wall of the filler supporting plate and the inner surface of annular slot Chamber is hit, the annular collision is intracavitary to be equipped at least one vibration ball, and the annular collision is intracavitary to be equipped with several protrusions, when vibration ball edge So that described filler layer is vibrated, the cylinder, which is equipped with, is used for band for the vibration ball and raised impact when annular collision chamber rotation Dynamic vibration ball along annular collision chamber rotation gas manifold and exhaust branch pipe, the gas manifold and exhaust branch pipe respectively with annular Collide chamber connection.The vibration of filler supporting plate may be implemented by shaking ball, thus not only contribute to attachment in removal filling block Impurity particle, and liquid can be made to form water mist by vibration when passing through in filling block, further increase gas-liquid contact Area.

An example according to the present invention, the cross section of the through-hole on the filler supporting plate are regular hexagon, and described logical Hole is located at the area that the area on filler supporting plate upper surface is located on filler supporting plate lower end surface greater than the through-hole.Regular hexagon knot The filling block stable structure of structure, and circumferential limit may be implemented, while avoiding well by up-small and down-big structure design The case where filling block falls off from filler supporting plate, and as vibration can make filling block be engaged to corresponding lead to automatically In hole.

An example according to the present invention, the center of described filler layer arches upward to form arc knot upward along the vertical direction Structure.Bow arcuate structure can be designed so that inner sidewall institute of the liquid after filling block along the outer surface of filler supporting plate towards cylinder Converge in position.

An example according to the present invention, the bottom chamber are equipped with inner cylinder, and the top of the inner cylinder is radially turned up Form the interconnecting piece that diameter is greater than inner diameter of steel flue, the inner sidewall connection of the interconnecting piece and cylinder.It may be implemented to give up by inner cylinder Gas enters after lower chambers to be cleaned in advance using centrifugal force, while can be along inner cylinder along the liquid that cylinder madial wall flows downward Inner sidewall flowing.

An example according to the present invention, the lower section of the inner cylinder are equipped with a wind deflector, the wind deflector and inner cylinder There are gaps between lower end surface, so that surrounding to form interior air inlet between the lower end surface of inner cylinder and the upper surface of wind deflector, institute State between the outer rim of wind deflector and the inner sidewall of cylinder that there are spacing.It can make the position in the lower chambers of cylinder by wind deflector Forming independent chamber in the lower section of wind deflector gathers the impurity particle in exhaust gas below wind deflector.

An example according to the present invention, the interior air inlet are equipped with several arcuate guide blades, the arcuate guide Blade is circumferentially sequentially arranged at intervals.Air inlet bore in not only further being reduced by arcuate guide blade, realizes pressurization, And acceleration rotation can be realized during air-flow enters inner cylinder.

An example according to the present invention, the inner cylinder is interior to be equipped at least one secondary filler material layer, the secondary filler material layer Position ring structure, the outer rim of the secondary filler material layer and the inner sidewall of inner cylinder connect, and the centre bit of the secondary filler material layer installs There is central passage.Cooperate the whirlwind in inner cylinder by secondary filler material layer, the secondary removal impurity particle of exhaust gas not only may be implemented, And the first time reciprocation of gas-liquid can be realized in secondary filler material layer.In addition the central passage on secondary filler material layer can be with The generation of stopping state effectively is avoided, and air-flow can be made by generating pressure change when central passage.

An example according to the present invention, the cylinder is interior to be located at equipped with isolation cover below wind deflector, and the isolation cover is in Up-small and down-big flared structure, the lower end of the isolation cover are fixedly connected with the inner sidewall of cylinder, so that the isolation cover Lateral wall and cylinder inner sidewall between surround to form the annular groove of an opening direction upward.It can be to avoid cylinder by isolation cover The fine particle that centrifugation removal of impurities in vivo generates avoids pipeline blockage close to inner tube or the link position of outer tube and cylinder body bottom Or even the blocking of spray system.

Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description Obviously, or practice through the invention is recognized.

Above-mentioned technical proposal has the following advantages that or repeatedly removes impurity then again the utility model has the advantages that having firstly, for exhaust gas The gas-liquid interaction of packing layer, therefore the long service life of packing layer are carried out, its opposite frequency of maintenance is relatively low, reduces enterprise Production cost passes through the net of the packing layer of multiple tracks its exhaust gas secondly, then exhaust gas enters back into packing layer by secondary filler material layer It is good to change effect.
