Description
Technical field
The utility model relates to inertia-type gas-liquid separation device, mainly can be used for flue gas desulfurization, steam turbine and needs to use the industrial occasions of corrugated plating liquid knockout except liquid etc.
Background technology
In current domestic industry application, common inertia-type gas-liquid separator still adopts traditional corrugated board structures, and structural shape comprises triangular wave card, trapezoidal wave card, asymmetric drift line style corrugated plating and on these template bases, adds the corrugated plating of the patterns such as straight hook, crotch, fluting.
As shown in Figure 1, the triangular wave card blade through multistage bending is arranged in parallel with the many rows of certain horizontal spacing, forms tortuous how curved flow channel space between every two panels corrugated plating.Gas with fine drop enters corrugated plating runner from device portal, is forced to carry out Tortuous flow along corrugated plate shape.Because gas followability is good, can flow out from the exit of device; And droplet inertia is comparatively large, can not follow gas in tortuous flow path well, from gas flow trace, skew is deviate from, and strikes on corrugated plating wall.Drop becomes liquid film in wall upper berth spread subsequently, along with gathering of liquid film is more and more, be affected by gravity, liquid film pools (perpendicular to the accompanying drawing 1 paper direction) flowing straight down of liquid stream, enter in the liquid phase returnable such as liquidceiver, gas-liquid two-phase is separated.There is a lot of problem in actual applications in this corrugated plating.First, when containing the electrolyte such as a large amount of calcium, magnesium or other insoluble impurity particles in liquid phase, can deposit at the bending tip of runner, produce scale formation, the dirt at most advanced and sophisticated place is difficult to smooth cleaning, and along with the growth of service time, runner there will be blocking, the separating property of whole device can decline greatly, and pressure drop loss obviously promotes.The best approach solving scale problems is exactly change under suspended state or clean corrugated plating piecewise, causes the waste of manpower and financial resources cost.Secondly, gas needs sharply bending in runner, and under the operating mode that gas speed is larger, the continuous collision of fluid turns to and causes great energy loss.Conventional triangular wave card is under the gas speed of 4 ~ 6m/s, and pressure drop even can reach more than 100Pa.
Fig. 2 is the streamlined corrugated plating of the asymmetric that another industry is commonly used.Such corrugated plating geometry is level and smooth, without sharp-pointed bending structure, effectively can reduce fouling and cleaning under being easy to non-intermittent condition of work.Fairshaped geometry can also make fluid significantly be reduced by pressure drop during runner.But compared to triangular wave card, the followability of drop in this runner is also increased.Under low gas velocity operating mode, the particle separation efficiency of equivalent diameter below 50 μm is lower, is also difficult to address this problem even Multi-row serial is arranged.
Chinese invention patent CN201110219753.8 provides a kind of corrugated board structures of improvement.Existing triangular wave point is changed into platform ripple point by this corrugated plating, and is provided with the blade of spacing 1.5mm, extension elongation 6mm at platform place.New construction makes drop in the gathering increased frequency at platform and blade place, improves the efficiency of gas-liquid separation.But the platform turning point of this plate still has sharp-pointed knuckle, easy fouling.Incrustation scale also can gap between blocking blades and plate, makes corrugated plating be difficult to cleaning, cannot reuse.
Chinese utility model patent CN200720040897.6 discloses a kind of Novel sheet bar being provided with concavo-convex drain structure on trapezoidal wave card.Its drain structure is inverted v-shaped, uses impact style to be processed to form, groove depth 30 ~ 40mm.In mounting arrangements, the spacing between two panels plate is between 220 ~ 420mm.Not easily there is reentrainment phenomenon in this plate, but still can not avoid scale formation.Because distance between plates is large, this device can not realize being separated to the drop of less equivalent diameter.
Chinese invention patent CN200610148271.7 provides a kind of new annular ripple plate.The radius of curvature of its blade arc is identical all the time, and between 1.2 ~ 2m, the height of blade is at more than 200mm.The critical flow velocity of reentrainment can be brought up to about 5.5 ~ 6.5m/s, the drop of this template to less equivalent diameter is difficult to realization and is separated completely.
Utility model content
For solving the problem, the utility model provides a kind of novel corrugated plating streamlined structure.After this corrugated plating is arranged in parallel according to the many rows of certain spacing, sharp-pointed bending structure is not had in the flow channel space formed, both fouling can be avoided, be easy to the cleaning under continuous duty, the separative efficiency of the drop of equivalent diameter below 20 μm can be significantly improved again, and ensure that droop loss is close with existing streamlined corrugated plating pressure drop.

Detailed description of the invention
After being arranged in parallel by the many rows of certain horizontal spacing by this corrugated plating, form a kind of flow channel space of new shape, as shown in Figure 4, along with the motion of band liquid gas in runner, width of flow path varies.Be embodied in, with gas flowing, runner successively experienced by narrow and---relaxes the process that---narrowing---relaxes again.In the both sides of circular arc projection, runner is restrainted narrow, and the droplet particles carried secretly in gas can deviate from the movement locus of air-flow, strikes wall to form liquid film and separated.After band liquid gas enters runner, along with narrowing of runner, a large amount of drop can strike the near wall of protruding front side; Because the width in protruding runner increases, the angle of revolution of fluid in elevated regions increases; Along with the second time bundle of runner is narrow, remaining droplet particles can impinge upon the near wall of protruding rear side.
This corrugated plating can adopt polyacrylic resin material (PP), by injection molded in shaping dies.Thickness δ can be worked into 0.5 ~ 3mm.Under preferred size condition, the maximum gauge of whole corrugated plating and the difference of minimum thickness are only 7 ± 0.5mm.Because polypropylene density is little, the corrugated cardboard sheet after shaping is lightweight, can be a large amount of in gas-liquid separation device, densely arranged, little to passive cantilever beam load, can improve the bulk strength of device.As being arranged in desulfurizing tower, also can effectively reduce tower body load.Corrugated plating after shaping has higher heat resistance, can continue use and ensure mechanical property in the environment of 110-120 DEG C.This corrugated plating surface property is good, and the liquid film being deposited on wall still can possess good mobility, the landing being conducive to liquid phase be separated.
This corrugated plating can adopt two kinds of arrangements in the application: horizontally disposed (see Fig. 5) and vertically layout (see Fig. 6).When corrugated plating is horizontally disposed, enter runner between corrugated plating containing liquid gas level, drop strikes on wall, is subject to Action of Gravity Field vertically landing, import and export direction and liquid phase off-direction containing liquid gas orthogonal, need separator vertically below drop retracting device is set.When corrugated plating is vertically arranged, enter corrugated plating runner straight up containing liquid gas, drop gravitate, along Way in oppositely landing downwards, imports and exports direction containing liquid gas parallel with liquid phase off-direction.
The arrangement pitch of corrugated plating is 15 ~ 40mm, and concrete spacing value is depending on gas speed working condition.Implement to fix in the mode of pull bar or fixture.Layout row and the height L of corrugated plating are determined by concrete separating treatment amount demand.
