Summary of the invention:
The objective of the invention is provides a kind of compact conformation to above-mentioned deficiency, the bispin stream water purifier of good purification.
Technical solution of the present invention is: bispin stream water purifier is formed by the pipe box dress of three layers of different-diameter, and wherein the cavity of outer layer sleeve and intermediate layer sleeve pipe formation is an one-level eddy flow cavity, and internal layer webmaster and intermediate layer sleeve pipe form secondary eddy flow cavity; Outer layer sleeve top is provided with the water inlet that feeds one-level eddy flow cavity, and the bottom is established dirt and collected decanting zone and sewage draining exit in the outer layer sleeve; Section surface tangentially has into water angular cut in the sleeve pipe of intermediate layer, and outer surface is twining spiral swirl vane and spiral eddy flow lower blade, leaves the space between blade and the outer layer sleeve, does not have the space between lower blade and the outer layer sleeve; Inner layer net cannon born frame outer surface is provided with screen pack, and communicates with pure water inlet.
The present invention adopts " Trinity " design, and promptly a table apparatus can be realized three filtration, purification functions under the situation of not using external power.Trade effluent installs disposable purification through this just can reach the standard that industrial turbid circulating water recycles, and satisfies the quantity-produced needs.
The structure and the principle of this bispin stream water purifier: the present invention adopts the seamless steel pipe of three layers of concentric different tube diameters (according to the treatment scale decision) to carry out suit and forms three cavitys that are mutually related, and sewage tangentially gets into the cylindric tube chamber container of the first order from the outside and the generation of forced rotational flow field makes water and dirt separation.Adopt the design of spiral swirl vane rotary fluid in the cavity; Leave the slit of 10~20mm between the edge of blade and the outer layer sleeve inwall; Realize the water dirt separation, prolong the downward sedimentation of tube wall in the rotation, use or flow back to sedimentation basin to the less important position of blowdown confession so that dirt is mixed in.
Water through the comparatively cleaning after the initial gross separation passes through the tangential slit of intermediate layer sleeve pipe; Get into second level cavity interior (between intermediate layer sleeve pipe and the internal layer webmaster) and force rotation with higher speed; Carry out secondary purification and separate, sewage is settled down to sewage draining exit downwards along tube wall to carry out the use of less important position or enters sedimentation basin handling.
Treated purifying waste water reaches spendable standard, and at last through filtering net cylinder, system equipment without interruption uses.Be to utilize the characteristics design of water to become specific rotational structure form to make it to become desirable water purifying equipment.
Advantage of the present invention is: adopt " Trinity " design, can realize three filtration, purification functions.1, can realize three-stage filtration at one stroke, that is: preliminary filtration, middle fine filtering and final the filtration are satisfied the aspects trend that requirement improves constantly to water supply quality such as existing industrial dedusting, cooling, flushing.2, disposable realization water quality reaching standard uses; And treating capacity is bigger; In industries such as metallurgy, cement, can realize the closed cycle of sewage disposal and instant regeneration, the regeneration ratio that improves water reaches more than 90%; Promote the sewage zero-discharge of key industry, the saving of water resource is had strategic value.3, have the big characteristics of sewage quantity that volume is little, handle, the investment that can save a large sum of sewage-farm has tangible economic advantages.4, particularly the steam fog nozzle of industry use, drive nozzle reach than long pipe runs in long-term the use, do not reach the pollutant deposition obstruction that requires water quality to cause because of being forced to have used, and have become a difficult problem in the industry, and the present invention can fundamentally crack this difficult problem.5, because the effect of eddy flow, the bottom filtering net cylinder can realize from washing capacity, improves filtering net cylinder service life, reduces the labour intensity of operator's cleaning and filtering net tube, can realize the periodic replacement of filtering net cylinder.
To combine embodiment that embodiment of the present invention is described in further detail below.
The specific embodiment
Referring to accompanying drawing; Bispin stream water purifier is formed by the pipe box dress of three layers of different-diameter; Wherein outer layer sleeve 10 is an one-level eddy flow cavity with the cavity that intermediate layer sleeve pipe 8 forms, and internal layer webmaster 11 forms secondary eddy flow cavity, one-level eddy flow cavity, secondary eddy flow cavity upper end closed with intermediate layer sleeve pipe 8.Outer layer sleeve 10 tops are provided with the water inlet 1 that feeds one-level eddy flow cavity, and the bottom is established dirt and collected decanting zone 5 and sewage draining exit 6 in the outer layer sleeve 10; Section surface tangentially has into water angular cut 3 in the intermediate layer sleeve pipe 8, and outer surface is twining spiral swirl vane 2 and spiral eddy flow lower blade 4, leaves the space between swirl vane 2 and the outer layer sleeve 10, does not have the space between eddy flow lower blade 4 and the outer layer sleeve 10; Internal layer webmaster 11 skeleton outer surfaces are provided with screen pack 7, and communicate with pure water inlet 9.
Principle: sewage is oriented in a tangential direction from water inlet 1 and circular container and gets into the one-level eddy flow and purify chamber (between outer layer sleeve 10 and the intermediate layer sleeve pipe 8), and the water through swirl vane 2 forms the pressure rotational flow field, leaves the slit between the inwall of the outer rim of swirl vane 2 and outer layer sleeve 10; Under action of centrifugal force, after bigger dirt is deposited to eddy flow lower blade 4 along outer layer sleeve 10 inwalls, along the stationary conduit of eddy flow; Rotating flow is collected decanting zone 5 (cavity) to dirt, and water is behind rotation one fixing turn, and the current of preliminary purification tangentially get into the angular cut of opening on the intermediate layer sleeve pipe 83; Get into the secondary eddy flow and purify chamber (between intermediate layer sleeve pipe 8 and the internal layer webmaster 11); Speed eddy flow with higher makes tiny dirt, and the inwall rotation that continues the sleeve pipe 8 along the intermediate layer is settled down to dirt and collects decanting zone 5 (cone); And descending the exit to import the eddy flow field that bulky grain is mingled with; Make the dirt eddy flow lead to sewage draining exit 6, water purification flows to water purification pipe outlet 9 through filter screen 7, realizes three grades of purifications of sewage.
