Embodiment Construction

[0007] As shown in the accompanying drawings, the muddy water enters the bottom of the siphon riser 3 through the water inlet distribution tank 1 and the water inlet pipe 2, and the bottom of the siphon riser 3 enters the lower part of the top cover 4. There is a circle of small holes, and the muddy water flows from the The small hole flows out, flows evenly in all directions on the baffle plate 5, and then passes through the upper movable orifice plate 12 and the fiber bundle filter material 6, and enters the lower cavity 7 of the tank body, which is for filtered water, which flows from the lower cavity 7 of the tank body. It rises to the backwash water tank 9 through the connecting pipe 8 . When the water level of the backwash water tank 9 reaches the water outlet 10, it overflows into the clear water pool.

[0008] As the filtration time prolongs, the fiber bundle filter material layer 6 is continuously fouled, the water head loss increases gradually, and the water level in...

Abstract

Belonging to the field of environmental protection equipment, the invention relates to a full-automatic efficient fiber bundle valveless filter. According to the invention, a fiber bundle filter material is used in the valveless filter, and a gas water mixture is adopted for backwashing; a supporting layer composed of a rigid particulate filter material is added below the fiber bundle filter material; and a gas distributing device is arranged between the fiber bundle filter material and the supporting layer. The upper part of a siphon downcomer is provided with a pressure power switch. When water in a siphon riser pipe overflows from the siphon top and flows downward in the siphon downcomer, the water pressure makes the pressure power switch turned on, an electrically operated valve is opened, and compressed air enters a backwashing water flow through the gas distributing device. When the backwashing is over, water in the siphon downcomer descends to a normal water level, and after removal of the water pressure, the pressure power switch reset and outage occurs, the electrically operated valve is closed, and the filter starts to work again. The invention provides the efficient full-automatic fiber bundle valveless filter, the filtration effect and backwashing effect are enhanced, and the effluent water quality is improved.

Description

technical field [0001] A fully automatic high-efficiency fiber bundle valveless filter belongs to the field of environmental protection equipment. Background technique [0002] The valveless filter is the earliest valveless filter device in China that does not need valves and control instruments, and cleverly utilizes the siphon principle to realize automatic operation. Convenience and other advantages. The high-efficiency fiber bundle filter uses bundled soft filler-fiber as the filter element of the filter. The diameter of bundled fibers ranges from several microns to tens of microns, and has the characteristics of large specific surface area, strong adsorption capacity, and low filtration resistance. The high-efficiency fiber bundle filter controls its working process through valves. When backwashing, the fiber bundle is under the action of compressed air and backwash water, and the fiber bundle is in a state of constant shaking. Under the action of hydraulic force and ...
