Abstract
The invention discloses a device for increasing a smoke emission height of a chimney. The device is characterized by comprising an upper fixed plate, a lower movable plate and a drive device, wherein the upper fixed plate separates a top cavity of the chimney, and a center hole which can generate a smoke vortex ring is formed in the upper fixed plate; the drive device is connected with a vertical transmission rod located on middle axes of the upper fixed plate and the lower movable plate, and the drive device drives the lower movable plate to longitudinally reciprocate through the vertical transmission rod; and smoke existing between the upper fixed plate and the lower movable plate during the reciprocating motion of the lower movable plate is compressed, the compressed smoke generates the smoke vortex ring through the center hole, and the smoke vortex ring is upwards sprayed out of the chimney and discharged to the air. Under the condition that a little cost is increased, the method can improve the smoke emission height to be over two times of the height of a conventional chimney with the same dimension specification, contributes to improvement of air environments of cities and towns, and has good social and economic benefits.
Description
Technical field
The present invention relates to a kind of device that promotes the soot emissions height of chimney.
Background technology
Chimney is the key facility that discharges at present flue dust, also is the important pollution sources of cities and towns ambient atmosphere environment.Although taked reduction dust granules and sulphur removal, except the measure such as nitre, discharged flue dust and contain a large amount of fine dusts and toxic and harmful.In order to prevent the sedimentation around the chimney of these flue dust, cause the local environment serious pollution, often adopt the method for increasing chimney height, flue dust is displaced into higher aerial, utilize the air-flow in high-altitude to accelerate the flue dust diffusion.But because technology and cost, the construction height of chimney can be restricted, and flue dust also can't be displaced into higher height.In addition, take in addition to improve the method for flue dust flow velocity in the chimney, although the method helps to improve the height of release of flue dust, it is subject to the restrictions such as boiler specification, and the turbulence effect when entering atmosphere owing to flue dust promotes soot emissions effect limited highly.
Summary of the invention
Task of the present invention is to solve in the prior art defective that the soot emissions height institute technological means of taking that is used for promoting chimney exists, and a kind of soot emissions device highly that promotes chimney is provided.
Its technical solution is:
A kind of device that promotes the soot emissions height of chimney, comprise the top fixed head, the moving plate in below and drive unit, the top fixed head cuts off the top cavity of chimney, be provided with up the middle pit of the stomach that can generate the flue dust collar vortex on the fixed head, drive unit is fixed on the top of top fixed head by the drive unit support, drive unit is connected with a vertical type transmission bar, the vertical type transmission bar is positioned on the axis of the moving plate of top fixed head and below, the lower end of vertical type transmission bar is connected with the moving plate in below, and drive unit drives the moving plate in below by the vertical type transmission bar and moves back and forth in the vertical; Below moving plate move back and forth in the process to fixed head above entering with below flue dust between the moving plate compress, compressed flue dust through in pit of the stomach generation flue dust collar vortex, the flue dust collar vortex is discharged in the atmosphere after upwards ejecting chimney.
The moving plate in above-mentioned below is disc, leaves the annular gap between the moving plate in below and the inner wall of stack, so that flue dust enters the top of the moving plate in below; The middle pit of the stomach of top fixed head is circular, and its diameter is less than or equal to the diameter of the moving plate in below.
The present invention has following useful technique effect:
The present invention can be applied to transform existing chimney and newly-built chimney, in the situation that increases a small amount of cost, the height of release of flue dust can be brought up to more than the twice of existing unidimensional specification chimney, help to improve the cities and towns air ambient, have good economic results in society.
Description of drawings
Below in conjunction with accompanying drawing and the specific embodiment the present invention is further described:
Figure is the structural principle schematic diagram that the present invention promotes soot emissions a kind of embodiment of device highly of chimney.
Among the figure, 1. chimney, 2. moving plate, 3. vertical type transmission bar, 4. top fixed head, 5. drive unit support, 6. drive unit of below.
The specific embodiment
By reference to the accompanying drawings, a kind of device that promotes the soot emissions height of chimney, comprise top fixed head 4, the moving plate 2 in below and drive unit 6, the top fixed head cuts off the top cavity of chimney 1, be provided with up the middle pit of the stomach that can generate the flue dust collar vortex on the fixed head, drive unit is fixed on the top of top fixed head by drive unit support 5, drive unit is connected with a vertical type transmission bar 3, the vertical type transmission bar is positioned on the axis of the moving plate of top fixed head and below, the lower end of vertical type transmission bar is connected with the moving plate in below, and drive unit drives the moving plate in below by the vertical type transmission bar and moves back and forth in the vertical.Below moving plate move back and forth in the process to fixed head above entering with below flue dust between the moving plate compress, compressed flue dust through in pit of the stomach generation flue dust collar vortex, the flue dust collar vortex is discharged in the atmosphere after upwards ejecting chimney.
Preferably, in the aforesaid way, the moving plate in below is arranged to disc, leaves the annular gap between the moving plate in below and the inner wall of stack, so that flue dust enters the top of the moving plate in below.The middle pit of the stomach (hole) of top fixed head is circular, and the diameter at the described middle pit of the stomach (hole) is less than or equal to the diameter of the moving plate in below.
Operation principle of the present invention roughly is:
The one, cavity is set up anallobar at the top of chimney, and the flue dust that goes upward to anallobar is compressed;
The 2nd, above anallobar, set up flue dust collar vortex generating unit, after generating the flue dust collar vortex through flue dust collar vortex generating unit, then upwards eject chimney, the compressed flue dust of anallobar is discharged in the atmosphere.
Be up to the flue dust of anallobar from chimney bottom, below moving plate when moving downward, flue dust is able to be filled with between the moving plate of top fixed head and below from the peripheral space of moving plate, below, then moving plate is return moves upward in the below, the flue dust that is filled with is compressed, flue dust is forced to pit of the stomach ejection from the fixed head of top, forms the flue dust collar vortex.
Above-mentioned flue dust collar vortex, namely usually said " smoke ring ".The present invention utilizes the air dynamic behaviour of flue dust collar vortex, and in the long journey process, flue dust rotates and difficult diffusion around the circular section in ring week so that whole flue dust collar vortex makes progress, and that flue dust can be carried is higher farther.
The relevant technologies content of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this specification, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within protection scope of the present invention.
