Gravity-free valve filter (a) non-valve filter main features: non-valve filter is a no valve, run entirely by the hydraulic automatic control filter. It is divided into two kinds of gravity and pressure, gravity and more generally supporting the use of the clarifier, pressure does not exceed 150 degrees for the use of raw water turbidity for small, decentralized nature of the water supply project, but the same principle work principle of its work is the same, but the shape of the planar circular or square lines; (ii) non-valve filter constructed: valveless mainly consists of five parts, namely the top of the flush tank, the middle filter chamber, the bottom of the catchment chamber and the intake unit and flushing siphon devices. (C) valveless working process: running, runoff from the inlet into the filter, through the filter layer filtration, water flows into the upper portion of the connecting pipe from flush tank, after the tank is filled from the outlet pipe flows into the clean water tank . With the filter operation, the filter layer after interception resistance gradually increases, the water level rises siphon tube rising, when the water level reaches the siphon auxiliary nozzle tubes, sharp drops of water from the tube by suction will continue next the tube air away, generating a negative pressure in the siphon, so that siphon tube riser and falling water levels are rising quickly, the confluence of communication formed a siphon, forming automatic backwash. Thus, when the flush tank water level gradually decreased, down to the moment when the siphon tube mouth less air into the siphon, siphon action will be destroyed, that is the end of the washing process, then filter and reuse water, began circulating operation of a new cycle . (IV), use 1, next to the filter used in petrochemical, textile, electronic machinery and other industrial enterprises circulating cooling water treatment. 2, used in factories, cities, towns water plant filtration process. 3, used in swimming pools, fountains, water treatment water features. 4, it can also be used to filter and softening treatment of industrial waste water treatment applications. (V), the scope 1, for the water filtration treatment plant, the water suspension should be less than 15mg / L, effluent suspended solids less than 3mg / L. 2, for circulating cooling water side stream processing, water suspensions 15-30mg / L, effluent suspended solids is generally less than 5mg / L. 3, for the "dosing coagulation process", the influent suspended solids 50-100mg / L, effluent suspended solids is generally less than 5mg / L. (VI), the main design data 1, design filtration rate: 10m / h 2, the average backwash intensity: 15L / S.m2 3, backwash lasted: 3-5min 4, of the final head loss: 1.7m Tel: 18839788973 QQ: 2985530351
