Introduction:

This treatment device is by oil-water interlayer principle, separate the flotating oil layer by setting clapboard, achieve the purpose of oil and water separation. Inclined pipe settling device is a settling device which install Inclined pipe in the setting area, which separated into a series of shallow sediment layer in horizontal-flow or vertical-flow sediment device Utilizing tilt parallel tubes or cellular inclined pipe padding, the treated and subside sludge make movement each other and separation in each sediment device. The inclined pipe sediment device with high sediment efficiency and treatment effect steady, short retention time, small volume, small occupy area, convenient operation, thus widely used in removing solid in water supply and sewage treatment.

YM series steel inclined pipe sedimentator is composed of reaction chamber,opposite flow sedimentation and cleaning water area and mud bucket three parts, concentrate set in steel barrel--inside of inverted cone shell bottom tank. Raw water add coagulant blend by mixer, flow into reaction chamber in centre parts, after multilayer sieve plate and two segment vortex reaction , the suspended matter etc impurity coagulation form alum floc. The water flow rise inside of sediment area via honeycomb inclined tube, water present laminar conditions inside inclined tube, the suspended matter separate with water, the cleaning water rise and collect into water collecting tank outflow, sludge automatic glide to sludge-collecting hopper along with inclined pipe bottom.

Application scope

This equipment combine oil removal and sediment, not only can achieve the purpose of oil-water separation, but also further purify the water quality. There are lay many small diameter parallel inclined pipes in inclined sediment device, special with high removal effect to dispersity particle. Which is widely used in treating car washing sewage,industrial sewage,domestic sewage , Non-ferrous metal processing sewage, power plant ,Boiler room hydraulic dedusting sewage ,Gas station washing water ,biochemical water , pretreatment of water purification ,electroplating waste water and coating water etc.

Characteristic

(1)The equipment main parts adopt carbon steel,epoxy resin multilayer anticorrosive.

(2)Inclined pipe adopt special processing technic , inclined pipe use ratio reach 100%, increase disposal capacity, reduce floor area, the occupy area only a quarter of the horizontal-flow sediment device, sediment efficiency can raise 3-5 times.

(3) Adopting gravity manner in processing, no consume, reduce treatment cost.

(4)the accumulate mud can drop-in mud bucket, convenient to spoil disposal, reduce manual working strength of removal mud.

(5)good laminar conditions ,Particles subside free from turbulence interference, with high treatment effect to Difficult separating impurity such as colloid.

(6)when the inclined pipe length is 1m, work load according to 3-5t/m2·h design, V_O control in the range of 2.5-3.0mm/s, the outlet water quality is best.

(7)adopting honeycomb inclined pipe, pipe length is 2-3.0m,which can be safely operated in high turbidity with 50-100kg/m³ Clay sand content.

(8)the inclined sediment device adopt Ethylene-propylene copolymerization glass fiber reinforced plastic or PVC honey comb inclined pipe, the dip angle is 60°C,inclined length is 1m, inscribed circle diameter is 35-50mm, which can change inscribed circle according to water quality, in order to the best sediment effect.
