Description
Technical field
The utility model belongs to sewage treatment area, relates to a kind of coarse separation monoblock type ripple filter plate case.
Background technology
In the production run process of the heavy industry production fields such as oil field, petrochemical industry and thermal power plant; conventionally can produce a large amount of oily(waste)waters, if oily(waste)water directly discharges, meeting serious environment pollution on the one hand; also waste on the other hand water and oil, especially contained the boiler blow-down water that very high heat energy is worth.Be difficult to reach the standard of reuse for the processing of this oil-containing industrial sewage, especially the oil in water emulsion in water and dispersed oil are because output is large, difficult treatment becomes the key addressing the above problem.
In existing common technology, adopt coarse separation filter core method for emulsification oil handling in water, owing to limited by filter space, the quantity of Coalescence filter core is restricted more, causes its treatment capacity to be restricted; The coarse separation inclined plate packing and the fibrous bundle dump packing de-oiling efficiency that adopt are lower, are difficult to meet the requirement of high Precision Processing.
In prior art, multi-ply wood filler is to apply early, also be the most basic coarse separation filler, this filler often arrives the parallel thin plate of hundreds of layers in engineering equipment with tens layers, evenly be stacked together formation filling body by the interval of 5-20mm, weak point is mainly that effective flow area is less, affects filter plant serviceability.
Therefore, need to make further improvements filtration unit.
Summary of the invention
The purpose of this utility model is to provide a kind of coarse separation monoblock type ripple filter plate case, solves existing filtration unit filtration efficiency in the time processing oily(waste)water low, can not well realize the problem of oily water separation.
The utility model is achieved through the following technical solutions: monoblock type ripple filter plate case for coarse separation, comprises casing; In described casing, laterally parallel rows is shown polylith polypropylene board, has corrugation lobes, and have multiple apertures at the crest place of ripple on polypropylene board.
Further, the distance between described adjacent two polypropylene boards is 20-40mm.
Further, described ripple inclination angle is 45 °, and wavelength is 80-160mm.
Further, the diameter of described aperture is 10-16mm.
Further, the angle between described ripple and inflow direction is 20-30 °.
Adopt the positively effect of technique scheme: not only effective breakdown of emulsion of the utility model, and provide regular angled flow passages, in the time that water is passed through coalescing medium filling surface, adsorb, soak, collision, the process such as coalescent, emulsification or disperse phase oil droplet are grown up and form large drop or liquid film, under gravity and the mobile effect of fluid, liquid film or large drop remove from the end interfaces of coalescent passage, make the regular gathering of oil droplet and coalescent, thereby realize effective separation of profit; This device easily overhauls, simple in structure flexibly, treatment capacity is large.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of polypropylene board in Fig. 1;
In Fig. 3, a is the enlarged view of ripple on polypropylene board, b be in figure a A-A to sectional view.
In figure, 1 casing, 2 polypropylene boards, 3 apertures.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the vertical view of polypropylene board in Fig. 1, and as shown in the figure, monoblock type ripple filter plate case for coarse separation, comprises casing 1.The interior horizontal parallel rows of described casing 1 is shown polylith polypropylene board 2, on polypropylene board 2, has corrugation lobes, and has multiple apertures 3 at the crest place of ripple.Polypropylene material is lipophilicity material, in the time that water external emulsion passes through lipophilicity material, disperse phase oil droplet adheres at polypropylene material moistened surface, at this moment polypropylene material surface is almost encased by oil entirely, above the oil droplet that stream comes again also more easily soaks and is attached to, the continuous coalescent expansion of oil droplet of therefore adhering to also forms oil film.Along with the continuation of processing, the shock action of buoyancy and current makes oil film start to come off, thereby material surface is necessarily upgraded.The oil film coming off still forms oil droplet in water, but this oil droplet is than the large floating of oil bead diameter before coalescent, thereby reaches the object of coalescent deoiling.On polypropylene board, have corrugation lobes, in Fig. 3, a is the enlarged view of ripple on polypropylene board, b be in figure a A-A to sectional view, as shown in the figure, described ripple inclination angle is 45 °, wavelength is 80-160mm.The effect of polypropylene board is to increase coalescent pack surfaceness, can reduce the apparent wetting angle of filling surface, thereby improves oil-water separation.Distance in the utility model between adjacent two polypropylene boards 2 is 20-40mm.The effect of aperture is conveniently to gather the oil droplet at waved plate top to continue to float to separator top.In the utility model, the diameter of aperture 3 is 10-16mm.
Further, the angle between described ripple and inflow direction is 20-30 °, and Main Function is to provide tortuous passageway for fluid.Therefore, in the time filtering, water enters in casing, through tortuous passageway, during by coalescing medium filling surface, adsorb, soak, collision, the process such as coalescent, emulsification or disperse phase oil droplet are grown up form large drop or liquid film, under gravity and the mobile effect of fluid, liquid film or large drop remove from the end interfaces of coalescent passage, make the regular gathering of oil droplet and coalescent, thereby realize effective separation of profit, oil droplet continues to float to separator top after gathering waved plate top.
As the deoiling of wastewater of liquid liquid heterogeneous separation, most economical way remains gravity method, utilizes water and oily density variation, makes dispersed oil droplets buoyance lift in water and by the two separation.The same with the settlement separate process of liquid-solid system, in water, the buoyance lift separation efficiency of dispersed oil droplets is only relevant with buoyance lift area with the terminal velocity of oil droplet, and irrelevant with buoyance lift height, this so-called " shallow pond " principle.Another approach of strengthening profit gravity based separation process is coalescence technology, and tiny oil droplet adheres to formation larger oil droplet and accelerates its sepn process on surperficial oleophilic drainage solid matter.
This filter plate case filter material filler has changed the flow condition of water, increases the chance of colliding and being caught by filter plate at filling surface of drop, thereby improves oily water separation efficiency.Due to staggered perforation the in filter material filler fluid channel adjacent one another are, make box house fluid staggered mobile, greatly increase the coalescent probability of drop, also improve oily water separation efficiency.
The utility model as filter packing, for fluid provides tortuous passageway and the micro-inclination angle of surfaceness, has improved oil-water separation through specific structure with polypropylene board macromolecular material waved plate; It acts on to soak coalescent and collision coalescence simultaneously, has significantly improved coalescence efficiency.
The utility model is compared with existing coarse separation filter core method, and sewage load is large, stable, and maintenance cost is low.
