Description

The anti-granularity filter of automatic control Continuous Flow

The utility model belongs to the equipment of mechanical filter in a kind of water treatment facilities.

In water treatment facilities, using very, a kind of widely mechanical filter equipment is to adopt mechanical particle (quartz sand, anthracite, ceramic grain filter) filter bed that lays, utilize the filter bed particle that the sieve of the turbidity composition in the water body is blocked, cut-off filter effect purifying water body, mechanical filter construction equipment commonly used has filter-press, valveless filtering pool, rapid filter etc., these equipment are by the traditional filtering technology, adopt water body to flow through filter bed from top to down, when the filter bed knot tires out after certain load, unlatching from down and on current filter bed is carried out backwash, because the defective on the conventional process techniques, this class mechanical filter exists the pressure loss big, the energy consumption height, the filter bed narrow application range, the general secondary purification that only is suitable for the low turbidity water body, gap operation (the stagnation operation that unavoidable backwash process brings) is hardened with filter bed, and mud ball such as grows at defective.

The purpose of this utility model is the limitation that overcomes conventional process techniques, overcome the defective that the existing machinery filter plant exists, adopt the water body anti-granularity filtration means from bottom to top of filtering, utilize the fluidized state of generalized fluidization theoretical model guidance design filter bed and develop a kind of novel cleaning equipment, make equipment have automatic control, continuous, adapt to the wide mechanical filter of turbidity scope.

The purpose of this utility model is achieved through the following technical solutions:

The anti-granularity filter of a kind of automatic control Continuous Flow is made up of the control system that tower body, water distributing tray, block body, sand collecting nozzle, sand developing tube, sand-washing device, nozzle, water inlet pipe and water outlet pipe and pipeline are formed, and it is characterized in that:

A. tower body is made of the group section more than at least two sections, is provided with water distributing tray, sand collecting nozzle, nozzle, sand developing tube, block body, filtrate in the tower and forms anti-granularity fluidization filter bed, and the tower internal upper part is provided with cloth sand umbrella, sand-washing device, spilling water canal.

B. sand collecting nozzle and nozzle are installed in tower bottom, and nozzle connects with the compressed-air actuated pipeline of outside supply, and sand collecting nozzle connects with sand developing tube in the tower.

C. the open architecture be made up of bipyramid face plate of water distributing tray is let out the sand passage down.

D. block body is made up of some orthohexagonal vertical tubes in the tower.

E. sand-washing device by sand removing section, washed-out sand joint, down cone-plate, go up cone-plate, separate joint, demister is formed.

The utility model also can be described by following technical characterictic:

The sand power resources of carrying of the present utility model can be compressed air or pressure water source, are provided with the threeway, the valve control structure that realize by nozzle, sand hopper, sand-filling device and the blow-off pipe of additional injection filtrate, Pressure gauge etc.

The technical scheme that the utility model proposes is rule and the characteristics proposition of fluid bed cut-off filter turbidity material during according to the operation of anti-granularity, because water body enters filter bed from the bottom, water body carries out hydraulic classiciation to filter bed to be handled, filter bed shows varigrained lamination, oarse-grained filtrate is in the bottom, fine grain filtrate is on top, in filter bed, form the phase region scope that exists separately by varigrained particle, and the voidage of scope is tended towards stability, when water body filters, the bottom particle is big, voidage in the phase-stable area is also bigger, and the bed body is embodied in cut-off filter to large granular impurity to the filtration in the water, from bottom to top, the particle diameter of bed body dwindles gradually, the bed body that voidage is gradually little plays the sieving effect to the thin turbidity material in the water body, thereby guarantees the clean-up effect of water body, therefore, it is simple that this equipment has control, take up an area of little, compact conformation, the continuously technical performance of autocontrol operation, be a kind of novel, efficiently, be suitable for the wide advanced technology of turbidity.
