Description

The labyrinth type captation

Technical field

The utility model device is a kind of captation of water distribution uniformity, is installed in big flow, high flow rate, large diameter environmental protection and the industrial phlegma reuse advanced treatment equipment tank body.

Background technology

At present, in environmental protection water treating equipment and industrial phlegma reuse advanced treatment equipment, existing captation, usually adopt several forms such as baffle plate bed course, a main pipe type, common porous plate, multistage packing layer, these captations (can obtain fine application in≤60m/h) the equipment, but these equipment do not need to export filtrate external completely at low discharge, low flow velocity.For big flow, high flow rate, large diameter equipment, these captations just can not be suitable for, between the captation arm of female pipe certain distance is arranged, propping up female pipe has certain length, must be big in the other feed liquor amount of arm, and spacing intermediary flow is little, can not get well catchmenting, particularly for operation flow velocity high tankage, catchmenting is difficult to accomplish evenly, is not easy more external and for need the filtrate in the equipment is transferred out fully; The captation of multistage packing layer structure, owing to be the different packing material size layered arrangement of multilayer, big particle diameter below, small particle size in the above, when the fluid of high flow rate through out-of-date, fluid can be with a little filtrates to flow out by the macrobead filtrate, also have when big flow backwash or air bump rinse operation stirring, can make disorderly layer of up-small and down-big packing layer, influence normally catchmenting of equipment, this captation is not suitable for and filtrate need be exported in the external equipment fully; Common porous plate water cap structure is to have the filter in certain slit having to screw on the plate in a plurality of holes, when the water cap is arranged when even, can reach certain purpose of evenly catchmenting, but in the equipment of high flow rate, the liquid that catchments through porous plate water cap can form eddy current below porous plate, the homogeneity that influence is catchmented, on the other hand in the equipment of filling out the footpath greatly, because the spacing of water cap does not wait on header and the porous plate, cause near the porous plate water cap of header and exert oneself greatly, exerting oneself that distance is far away is little, cause the ununiformity of catchmenting, and the filtrate in the equipment being transferred out external requirement fully for need, common porous plate water cap structure is owing to catchment, the ununiformity of water distribution, it is external to cause filtrate all not transfer out.

Therefore, the captation that needs separates the liquid of access arrangement tank body in the liquid zone that goes out of industrial phlegma reuse advanced treatment equipment with filtrate in the equipment tank body, not only play the effect of evenly catchmenting, and can thoroughly transfer out filtrate in the equipment external, be applicable to the external regeneration ion-exchanger, the equipment such as strainer of external cleaning filtrate, be particularly useful for big flow, high flow rate, effluent quality is had relatively high expectations, the environmental protection equipment of the extracorporeal treatment filtrate that the filtrate breakage rate is lower, be specially adapted to be equipped with the high speed interchanger of the external regeneration of resin particle, can reach energy-conservation, the purpose of environmental protection.

Summary of the invention

The utility model purpose is: propose a kind of captation that is applicable to big stream reason, high flow rate, major diameter equipment, not only can evenly catchment, but also the filtrate in the equipment can be removed away up hill and dale, it is high relatively that this captation designs and produces requirement, the water yield is big, flow velocity is high, the homogeneity of catchmenting height, filtrate output rate height but handle.Be applicable to the environmental protection equipment of the extracorporeal treatment filtrate that big flow, high flow rate, effluent quality are had relatively high expectations, the filtrate breakage rate is lower, be specially adapted to be equipped with the external regeneration high speed ion interchanger of resin particle, can reach the purpose of energy-saving and environmental protection.

Technical solution of the present utility model is: the labyrinth type captation comprises the arc porous plate, is fixed on some filter caps, labyrinth drip ring, catchment area end socket, vortex eliminator and discharge nozzle on the porous plate; The filter cap is vertical with junction arc porous plate normal with the connection request filter cap medullary ray of arc porous plate, arc porous plate filter cap below is provided with respectively the catchment labyrinth drip ring of resistance drop a little of adjusting, arc porous plate below is provided with the catchment area, and the header ingress of catchment area is provided with vortex eliminator; Described labyrinth drip ring has multilayer, and the concrete number of plies is decided according to device diameters, and along with the increase of device diameters, the number of plies of labyrinth drip ring also increases gradually; Drip ring bottom, labyrinth has the oblong aperture of Great Wall shape, also is provided with vortex eliminator between catchment area and header, prevents to form eddy current at the header place of catchment area.

Porous plate has certain radian, loosening when radian should guarantee evenly to catchment and guarantee again that filtrate is carried, and its radian of different filtrates is different, generally determines a radian that is suitable for a certain filtrate at the trial; The radian of arc determines that according to the kind of filtrate for ion exchange resin, its radian is generally between 0.7 ~ 0.8 degree (camber line and horizontal included angle A are 10 ~ 12 °).

The filter cap can separate filtrate and treatment media, and the quantity of filter cap can the filtration capacity under a certain pressure reduction be determined according to the required processing water yield and each filter cap; The labyrinth drip ring has multilayer, and the concrete number of plies is decided according to device diameters, and along with the increase of device diameters, the number of plies of labyrinth drip ring also increases gradually; Drip ring bottom, labyrinth has the oblong aperture of Great Wall shape, facing a layer perforate is staggeredly arranged as the labyrinth, outer, the density height of perforate is that the area of perforate is big on the unit surface, ecto-entad, the density of perforate reduces gradually, when obtaining water distribution uniformity, can reduce the overall resistance of captation greatly like this; The catchment area end socket generally adopts ellipse or torispherical head, and its specification can be chosen the catchment area end socket that is complementary with device diameters as far as possible according to the diameter of selected equipment, and the collection and treatment medium connects header simultaneously; Also be provided with vortex eliminator between catchment area and header, prevent to form eddy current at the header place of catchment area, vortex eliminator can be selected according to the caliber of header.

The beneficial effect of the utility model labyrinth type captation: (1) in big flow, high flow rate (〉=60m/h, even reach 120m/h), major diameter (big arbitrarily) equipment water distribution, catchment evenly; (2) in the high tankage of pressure-bearing, do not increase resistance, can save the manufacturing cost of equipment; (3) improve the cycle of operation, energy efficient and the acid-base consumption of big flow, high flow rate, major diameter operational outfit.(4) be specially adapted to the demanding equipment of big flow, high flow rate, effluent quality of external regeneration in the industrial phlegma reuse advanced treatment.
