Description

High-efficience combined tube mixture flocculating unit

The utility model is the special equipment of feedwater treatment and purification, is used for the mixed flocculation operation that the water engineering water treatment purifies.

Current, occurred variform blender monomer both at home and abroad respectively,, lacked the reaction unit of finishing flocculation and poly-necessary waterpower of attached stage or machinery though can provide efficient mixing for former water, make flocculation, poly-attached effect be subjected to certain limitation, and the loss of flood peak, medicine consumption, energy consumption are big.The tubular type diffusion mixer or the tubular static mixer of particularly domestic band tapered cap need to build six reaction tanks and set up consersion unit at back one reaction process of mixed flocculation, and floor space is big, the cost height.

The purpose of this utility model is to be efficient that improves the mixed flocculation in the handling technology of water supply and the assembled tube type mixed flocculation device that effect designs.

The utility model is to adopt the assembled tube type flocculation, its operation principle is: former water (referring to rivers water) and coagulant, flocculation aid fully mixes at a high speed, make coagulant under the Brownian movement domination, evenly spread, fully contact with suspended particulates in the water, generate electrically charged colloidal solid, through the turbulent transition state of certain hour, the early stage condition that reaches the absorption suspension and the suede body is formed is formed small solid alumen ustum gradually by colloidal solid.The poly-attached reaction unit that depends on various waterpower or machinery of the continuation of flco is finished.The utility model is that mixed flocculation and poly-attached required waterpower or automatic reaction device are combined in one section three meters long aqueduct, as Fig. 1, when the water inlet (1) of former water by two differing heights and the certain angle that interlaces enters in the water tank, then the current of two strands of different directions form the eddy flow of the automatic mixing of rolling up and down, the blade of centrifugal pan (2) is subjected to eddy flow to impact rotation, then coil herb liquid under action of centrifugal force, along the garden week diffusion of dish, the shape that becomes to loose is involved in eddy flow to be mixed with water.Current make the triangle body (3) of the water impact case bottom protrusion of rotation through the effect of arc orifice plate (4), form dynamic waterpower mixing effect in water tank, and soup obtains instantaneous and sufficient mixing.The former water that injects medicament promotes the blade of agitator (8) behind plane orifice plate (5), telescopic joint (6), make it rotation, carries out the waterpower dynamic agitation.This moment, flow velocity slowed down, and was controlled at the former water of 0.6～0.7 meter per second and began flocculation process just.Current pass through several roads disturbing flow device again, cause the particle collision opportunity, are beneficial to preliminary knot suede.At first pass through left-handed deflector (9), square pore (10), again through dextrorotation deflector (11), square pore (12), current are steady, and then former water is finished the mixed flocculation process and is flowed out through a minute water awl cap (13), the stable reaction tank that enters.Flocculator of the present utility model, (2) structure of centrifugal pan in the water tank such as Fig. 2, centrifugal pan is supported in rotating shaft (15), is fixed on the water tank wall by bearing block (16) and (18), the blade that some is housed perpendicular to rotating shaft is gone up in rotating shaft (15), and blade is accepted water impact and driven the centrifugal pan rotation.Above centrifugal pan, liquid injection pipe (14) is housed, soup is injected in the centrifugal pan by liquid injection pipe.Fig. 1 intermediate cam body (3) is the solid of oblique triangular prism, and the bottom surface connects with water tank, and a faceted pebble connects with arc orifice plate (4).The triangle height is 1/3rd of a water tank height, and its effect is that feedwater flow is placed obstacles, and produces the effect of multiple impact, quickens soup and the even rapid mixing of water.Be drilled with several shunting apertures on the arc orifice plate (4), play the current divider effect.Plane plate hole (5) is to shunt barrier in the water tank at last together, and it is the aperture that bores some on a straight iron plate, is vertically welded in the water tank.Water-supply-pipe (7) is that hydraulic agitator (8) and current disturbing flow device (9), (10), (11), (12), (13) are housed in one section three meters long water-supply-pipe.Hydraulic agitator (8) is the impeller mechanism of similar fan, on the axle in housing with bearing movingly five equilibrium three impellers are housed, three gripper shoes of five equilibrium welding on the housing, the other end is welded on the water delivery tube wall.The effect that waterpower stirs is by the hydro powered rotation, and the current that enter are once stirred again.The current disturbing flow device is revolved deflector and two square pores and is divided water awl cap to form by left and right.Deflector (9) (11) is that the steel plate bar by certain width axially becomes certain spiral angle to be welded on the water wall with water pipe, forms two groups of deflectors of the left and right hand of spiral.A left side, after the right-hand screw deflector, the square pore (10) that makes the current forward is arranged, (12), its structure such as Fig. 3, the direction that promptly in water pipe, parallels to the axis, section be approximately foursquare have certain altitude in connect the quadrangular hole, but each faceted pebble does not join, two limits on faceted pebble directly are welded on the water wall, two is back cover not, and dividing water awl cap (13) is the last outlet of flocculator current, structure such as Fig. 4, be on the garden conical surface of back cover not, trisection is with a certain distance from the garden of the vertex of a cone, and the corresponding camber line of intercepting couples together on awl garden, the end, form the taper three-jaw, clip part beyond the three-jaw, and with the vertex of a cone stream that meets water, three-jaw is welded on the water wall.

Mixed flocculation device of the present utility model in the theoretical application of mixed flocculation, organically combines streamflow regime, energy consumption, medicine consumption and the poly-attached operation in postorder stage, and application is considered in unification.Particularly will mix with flocculation process gathering together, raise the efficiency, shorten the time of later process reaction.Use the principle of free turbulent flow, in one section water-supply-pipe, disturbing flow device is set, utilize the kinetic energy of current itself, carry out turbulent fluctuation at a slow speed.Through repeatedly flow-disturbing metamorphosis, cause collision opportunity between the particle, impel flocculation suede just.Device adopts particular geometric shapes, prevented the broken and sinking of preliminary knot suede particle, suspended particulate is reached fully take off surely, be the poly-attached condition of having created of next procedure, and make later process reduce to only reaction tank of need by six reaction tanks, this assembled tube type mixed flocculation device can be installed near reaction tank, and operation is combined closely about making, performance complex art effect.
