Background technology
Now widely used is deflection plate demister, its according to principles such as the inertia of drop, centrifugal force, shock, gravity except mist dedusting.Flue gas passes through blade, and the gas containing droplet changes direction through several times, and droplet, under the effect of inertia and centrifugal force, is got rid of on blade, thus realizes gas-liquid separation, and the droplet on blade accumulates bulky grain drop, falls by gravity.Deflection plate demister has simple in construction, high to the capture rate of medium size and large scale droplet, and pressure drop ratio is relatively low, be prone to rinse, and has worn-out open architecture and is easy to maintenance and the feature such as expense is relatively low.But along with the enforcement of " minimum discharge " standard, this structure is difficult to reach to design requirement again.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of mechanical centrifugal except mist dust arrester, device is positioned at the absorption tower the superiors, it is only second to exhanst gas outlet bottom, gas is by producing rotation in uphill process during this device, the droplet of air-flow entrained with gets rid of under the influence of centrifugal force and realizes except mist dedusting to demister tube wall.
For solving above-mentioned technical problem, the technical solution of the utility model is:
A kind of mechanical centrifugal is except mist dust arrester, including upper face plate, lower face plate and some demister barrel masts being fixedly arranged between upper face plate and lower face plate, described demister barrel mast includes exterior cover pipeline, the center of described exterior cover pipeline is provided with wash tub pipe along the length direction of exterior cover pipeline, some nozzle is distributed on described wash tub pipe, in described exterior cover pipeline, is provided with the first spiral board, venturi and the second spiral board the most with one heart.
Preferably, some described demister barrel masts are Spaced distribution.
Preferably, described exterior cover pipeline top is provided with pipe cap.
Preferably, described exterior cover pipeline upper end sidewall is provided with osculum.
Preferably, described nozzle being provided above near the first spiral board and the second spiral board.
Preferably, the blade of described first spiral board and the second spiral board and the angle of horizontal plane are 30 ° ~ 50 °.
Preferably, the adjacent blades floor projection Duplication of described first spiral board and the second spiral board is-5% ~ 30%.
Preferably, the inner core external diameter of described first spiral board and the second spiral board and the ratio of urceolus internal diameter are 0.25 ~ 0.5.
Preferably, the described blade of the first spiral board wants big relative to the blade of the second spiral board with the angle of horizontal plane with the angle of horizontal plane.
Compared with prior art, the beneficial effects of the utility model are: during work, gas is in uphill process, rotate by producing during the spiral board of bottom, the dense fog of air-flow entrained with drips to get rid of under the influence of centrifugal force and is separated for the first time to demister tube wall, and at this moment the flue gas containing fine drop separates through higher level's spiral board after Venturi rectifying again.The droplet being thrown on tube wall is pooled liquid stream and flows to, above lower face plate, then be discharged by drainage system along tube wall.It addition, mechanical centrifugal can reduce the escape of edge's steam except the pipe cap that the mist dust arrester mouth of pipe is arranged, the liquid stream of convergence can be discharged by the osculum from tube wall upper end.
