Long cellosilk high-speed filter

Abstract

The long-fiber high-speed filter of the present invention is a high-speed filter with long-fiber as the filter material. The filter mainly includes a filter cylinder, a long-fiber high-speed filter assembly, an embedded flange connection device, a direct Multi-ring perforated tube gas distributor, axisymmetric water inlet distributor with central water inlet and peripheral water outlet, grid type gas and water separator, etc., among which, long fiber high-speed filter components are installed in the filter cylinder, and long fiber high-speed The lower part of the filter assembly is equipped with a gas distributor, and the backwash inlet pipe is directly connected to the gas distributor. The filtered water and backwash water inlet pipes are installed at the bottom of the lower cylinder, and the water inlet distribution is installed on the upper part of the long fiber high-speed filter assembly in the filter cylinder. The outlet end of the water inlet pipe is located in the center of the water inlet distributor, the overflow and backwash outlet pipe is located on the side of the upper part of the filter cylinder, and a gas-water separator is installed in the movable cap on the upper part of the filter cylinder. The top is an umbrella-shaped air outlet.

Description

1. Technical field [0001] The invention relates to a high-speed filter using long fibers as the filter material, and belongs to the technical field of filter treatment of water supply and various sewage (waste water). 2. Background technology [0002] Filtration is one of the most commonly used treatment processes for removing suspended solids (turbidity) and its adsorbed substances in various types of water treatment. In order to ensure the quality of the filtered water, the currently used sand filter often uses quartz sand with a particle size of less than 1mm as the filter material, resulting in: ① low porosity of the filter layer, large filtration resistance, and low filtration speed; ② small specific surface area of ​​the filter material , Low dirt-holding capacity, short backwashing cycle; ③The filter material has a large specificity, difficult backwashing, high energy consumption, and the filter material is easy to lose. [0003] Fiber ball filtration is difficult to...

Problems solved by technology

In order to ensure the quality of the filtered water, the currently used sand filter often uses quartz sand with a particle size of less than 1mm as the filter material, resulting in: ① low porosity of the filter layer, large filtration resistance, and low filtration speed; ② small specific surface area of ​​the filter material , Low dirt-holding capacity, short backwashing cycle; ③The filter material has a large specificity, difficult backwashing, high energy consumption, and the filter material is easy to lose

[0003] Fiber ball filtration is difficult to be effectively cleaned due to the closed structure of the fiber ball and the group floating during backwashing, which affects the continuous effect of filtration

[0004] Filtration of long fibers fixed at both ends is difficult to fully clean the attached substances due to the small degree of freedom of the fiber filaments, which affects the continuous effect of filtration
