Description
Technical field
The utility model belongs to technical field of water treatment equipment, particularly relates to a kind of pipe-line mixer.
Background technology
Pipe-line mixer also claims tubular static mixer, at chemical industry, environmental protection, to adding various coagulant in the fields such as water treatment, flocculation aid, ozone, liquid chlorine and acid-base neutralization, the aspects such as mixing wastewater with air are all very effective, it is the ideal equipment that process water and various medicament realize rapid mixing, have and rapidly and efficiently mix, save the features such as energy consumption, do not needing in outer power situation, current can produce shunting by pipe-line mixer, intersect and mix and reverse eddy flow three effect, make the medicament that adds rapid, be diffused in whole water body equably, reach the object of moment rapid mixing, mixing efficiency is high, dosing can be saved.
Pipe-line mixer is generally made up of pipeline shell, hybrid element, chemical feed pipe, and hybrid element is fixed in pipeline shell.For the water of high concentrtion, traditional mechanical agitation mixing is poor with pore chamber mixed effect, and the use of tubular static mixer makes mixed effect be significantly improved, and meets the requirement of rapid mixing.During use, utilize the pouring liquid equipment such as water pump pending water and liquid medicine to be filled in pipe-line mixer and form current, by the disturbance of hybrid element to current being fixed on pipeline shell, make pending water and liquid medicine, two strands or a plurality of fluids produce cutting, shearing, the rotation of liquid and again mix, reach fine dispersion and well-mixed object between fluid.As can be seen here, the distribution of hybrid element in pipeline shell and the mixing efficiency of structure on pipe-line mixer have direct impact, and the form that hybrid element is conventional has spiral plate type and staggered board-like two kinds.
In the pipe-line mixer of spiral plate type, hybrid blade is fixing, the shape of hybrid blade is rectangle by middle part, two ends are the spirality that the arc plate distortion 180 ° being converted into certain angle is formed, several spiral mixing vane are distributed in pipe body with different rotatable phases along pipe body axial location, thus the eddy current allowing current form different directions in different section mixes, fluid is produced by it and flows to change, there is turbulent phenomenon thus improve mixing efficiency, mainly to flow segmentation, radial mixing, reversely rotate, the continuous fierce mixing and diffusion of two media, reach mixing object, fluid passes through it except generation step-down, without the need to extra power.But do not play immixture in the scope of one section of rectangular plate in the middle part of hybrid blade, the scope of spiral mixing vane disturbance is very limited, the local current be only positioned near pipe body axial location can be able to spiral disturbance, and the large multi-fluid near pipe body inwall is still following current, cause the mixing efficiency of spiral plate type pipe-line mixer not high, and the loss of flood peak is large.
In staggered board-like pipe-line mixer, hybrid blade is fixed on pipe body inwall and perpendicular to the plate body of pipe body axis, several hybrid blades are axially alternately distributed along pipe body, the turbulent water of this structure strengthens to some extent relative to spiral plate type pipe-line mixer, can reach higher mixing efficiency.
As can be seen from the above analysis, existing pipe-line mixer, no matter be the pipe-line mixer of spiral plate type or staggered board-like pipe-line mixer, mainly through hybrid blade, current are cut, shunting, and these hybrid blades are all be fixed on pipe body inwall, not quick detachable, maintenance is inconvenient, especially at the river that process turbidity is higher, during sewage, after longtime running, particularly suspension easy to hang in cross vanes in pipe body, cause current not smooth, flow velocity is slack-off, also easily cause sedimentation in water, blocking pipe blender, not only mixed effect can be had a strong impact on, the resistance of system is also made to increase, to ensure certain discharge pressure, the pouring liquid equipment such as water pump needs to provide larger and enters water injection pressure, cause the increase of energy consumption and use cost.And the equal more complicated of structure, manufacturing cost is high.
