Abstract

The invention provides a sector load water collector, and belongs to the technical field of filter water treatment, aiming at overcoming the defect of water resource waste due to filter load waste, low equipment operation efficiency and short regeneration period caused by equal water collection load of a water collector in existing filter tanks. According to the principle of matching with a sector water collection load, permeable gaps or meshes are formed in a water collecting branch pipe, and the density of permeable gaps or meshes in the water collecting branch pipe, distributed from the center end of a tank body to the side wall end of the tank body, is gradually increased, so that sector distributed water collection load is carried by the water collecting branch pipe in the length direction.

Description

Covering of the fan load water collector

Art

A kind of covering of the fan load water collector, belongs to filtration water-treatment technology field.

Background technology

Water collector used in currently known filtration water treatment facilities, or claim lower water-dispensing device, its Shi You center is derived Head is constituted in the radial collection branch pipe in center with several, and permeable gap or net are uniform-distribution with its collection branch pipe Hole.Water collector is located at the bottom of filtering tank, and its effect is that the purified water oozed out from filter material layer is collected in collection branch pipe, respectively Water in individual collection branch pipe is pooled to center export head and outflow filter tank body again.There is following defect in this structure：Due to collection Water arm corresponds to the distribution of filtering tank cross section in fan shape, so collection branch pipe is from tank body center-side to tank wall End, the collection discharge that should be carried in its every segment length increase gradually, and are distributed in collection branch pipe general at present Permeable gap or the density of mesh be but uniform, effect that what which was realized catchment is just necessarily impartial.Therefore result in Relative to drainage mass flow discrepancy on tank body cross section etc., the filtration load carried by filtering material is just unequal, further leads Filtrate load is caused to waste, equipment operating efficiency is low, shorten the regeneration period and waste water resource.

The content of the invention

There is the impartial defect of collection Water l oad to overcome current water collector, the invention provides a kind of covering of the fan load catchments Device, efficiently solves the drawbacks described above that current water collector is present.

The technical solution adopted for the present invention to solve the technical problems is：According to the principle matched with covering of the fan collection Water l oad Permeable gap or mesh are opened up on collector pipe.Specifically design principle is：When the radius and water collector collection that determine filtering tank After the quantity of water arm, the load surface that catchments that every collector pipe should be carried just is now uniquely determined, this load surface that catchments It is a sector, the length of collector pipe carrys out scale with the radius of tank body to tank wall end from tank body center-side, corresponding to half Fan-shaped arc length Li at the Ri of footpath is exactly a definite value, after a radius increment Ri+r is given, the arc length produced by radius increment r Increment is negligible, and the sectorial area increment produced by such radius increment is as following formula：

Δ Si=1/2 (Ri+r) Li-1/2Ri Li=1/2 (r Li)

In the same manner, equally give after a radius increment r corresponding to radius Ri+1, produced sectorial area increment is：

Δ Si+1=1/2 (r Li+1)

The ratio of two area increases just has following relation：

Δ Si/ Δ Si+1=Li/Li+1

As area of the fan-shaped incremental area with permeable gap or mesh has definite value proportional relationship, so just can be with With at Li presenting set length of pipe Ri approximate with the ratio of Li+1 with Ri+1 at permeable gap or mesh area ratio, so The density content relation that permeable gap or mesh are opened up on collector pipe is determined that：

Ni=μ η Li/ σ

In formula, μ represents the permeable flow under unit arc length, and it is affected by filtrate density and filtering accuracy, be one Measure constant under imposing a condition；η represents the permeable gap area under specific discharge, and it receives the viscous system of permeable pressure reduction and liquid Number affects, and a measure constant in the case where imposing a condition；Li represents arc length of the sector at radius Ri；σ represents unit Permeable gap or the area of mesh, it is affected by filtering accuracy, is a design constant；Ni is exactly collection branch pipe at Ri Permeable gap or the density of mesh, that is, the number in permeable gap or mesh of the collection branch pipe at Ri.

The invention has the beneficial effects as follows, current water collector is compared, the permeable gap or net on this covering of the fan load water collector The density in hole increases from tank body center-side gradually to tank wall end, efficiently solves current water collector collection Water l oad equalization Problem, so as to avoid the waste of filtrate load, equipment operating efficiency is low, shorten the defect of regeneration period and waste water resource.
