Valveless filter
Ⅰ、Product overview
Valveless filter tank is a kind of fast filter tank without valve switching filtration and backwash process. It is composed of filter tank body, inlet device and siphon device.
Ⅱ、The working principle of
无The raw water of the valve filter enters into the water distributor of the valveless filter for even distribution, and then enters into the filter through the air isolation device. The gravity flow is used to filter from top to bottom. As the filter layer continuously intercepts suspended substances in the water, the resistance of the filter layer gradually increases, which makes the siphon water level rise. When the water level rises to the set position, it enters the suction device in the siphon auxiliary tube, and the air in the siphon tube is taken away by the hydraulic effect, thus forming negative pressure. When the negative pressure reaches the design value, the siphon will occur. At this time, the water in the tank will flow backwards, and the valveless filter will flow from the bottom to the bottom of the filter layer, so as to realize continuous backwashing and discharge the backwashing waste water to the sewage pipe. When the water level in the water tank drops to a certain value, the siphoning effect is destroyed and the backwash ends, and the valveless filter starts to work again.
Ⅲ、Structure
Valveless filter including the inlet pipe, water tank, aeration tank oxygen tube, gas/liquid separation, water distribution plate, filter chamber, fine filter layer, tank cleaning and rotational flow aeration tank, outlet pipe, rising siphon tube, siphon tube, the trachea, water extractor and the decrease of the siphon pipe, destruction or damage a pipe and drainage pipe, water and oxygen aeration melting box connected with the sink and gas-liquid separation tube connected to fine filter chamber, filtering chamber connected clear water tank, fresh water connected spiral flow aeration tank, the filter chamber and a rise in siphon tube connected, rising siphon tube and the decrease of the siphon tube connecting tubes, siphon tube, exhaust tube, the transition water ejector with siphon tubes connected, The failure tube is connected with the siphon rising tube and the siphon falling tube. The time control device is installed on the failure box, which can effectively adjust the time of backflushing, make the fine filter layer backflushing clean and thorough, and can quickly and efficiently filter out the impurities and harmful substances in the water, making the water become active and fresh.
Ⅳ、Using range
Application scope includes: swimming pool water treatment, natatorium water treatment, seawater natatorium water treatment, water park water treatment, surf pool water treatment, artificial river lake water treatment, fishpond water treatment, landscape water purification treatment, rainwater recovery and recycling, industrial circulating water treatment, sewage treatment and other water treatment projects.
