Description

A vertical fiber filter cloth filter

technical field

The invention belongs to the technical field of water treatment and relates to a water treatment device, in particular to a vertical fiber filter cloth filter tank which can make the filter tank run stably, be easy to overhaul and discharge mud cleanly.

Background technique

In recent years, with the improvement of sewage discharge standards, the requirements for water treatment processes are getting higher and higher. However, the existing raw water treatment processes generally have high operating costs, complex structures, and difficult cleaning of filter media. The existing sewage advanced treatment process generally has problems such as low filtration rate, large floor area, complicated control, difficult backwashing of filter material, and high operating cost.

According to the national "Discharge Standards for Urban Sewage Treatment Plants" (18918-2002), the effluent discharge is required to reach Class A level, and the suspended solids SS need to be treated in depth. At present, there are rotary disc filter, sand filter, V-shaped filter and so on in the market for advanced treatment to make SS water reach the standard. These advanced treatment processes generally have problems such as high operating costs, difficult cleaning of filter materials, complex structures, and difficult maintenance. For example: according to the overall situation of the equipment, the construction of the rotary disc filter is relatively high, and there must be a large elevation difference between the front and rear ends. The filter is the back end of the whole set of water treatment process. The liquid level height requirement at the front end of the process is relatively high. When the front end cannot meet the liquid level height requirement during civil construction, secondary lifting may occur or the pool body may appear underground or semi-underground. The maintenance and installation or civil engineering is complicated and heavy.

In recent years, the vertical sheet fiber filter cloth filter has been widely used because of its advantages such as small head loss, not easy to block, easy replacement of filter material, low energy consumption, and small footprint. The vertical piece fiber filter cloth filter generally includes the vertical piece fiber filter cloth installed vertically in the tank body, the suction pump device, the mobile driving device, and the moving vehicle device, which can be inserted between the vertical piece of fiber filter cloth A backwashing branch assembly for linear scanning backwashing with a piece of fiber filter cloth; among them, the mobile driving device includes a driving device, a driving track, and a driving device. The installation of the vertical sheet fiber filter cloth filter has higher requirements on the horizontal straightness of the track installation and the parallelism of the relative filter frame. However, in the actual operation of the existing vertical fiber filter cloth filter tank, the construction deviation of the on-site civil structure is often large, so that the driving track cannot be installed on a horizontal line, or the driving track and the filter frame are not installed parallel to each other. As a result, the mobile driving device cannot operate normally, and it is difficult to meet the normal and stable operation of the vertical sheet fiber filter cloth filter tank. In addition, according to the overall operation of the vertical fiber filter cloth filter, it is required that the vertical fiber filter cloth filter can be filtered during normal operation without affecting maintenance. The entire equipment can be fully automatic for a long time, with low equipment failure rate and easy installation. However, the actual operation of the existing vertical sheet fiber filter cloth filter tank is not quite satisfactory. In addition, the existing vertical sheet fiber filter cloth filter tank still has the problem of unclean sludge discharge due to unreasonable design.

The working principle of the present invention is as follows:

The sewage enters the raw water area A from the raw water inlet 1 at the front end of the filter through the pipeline or weir gate. In the filter tank C, the water surface height is higher than the filter unit 7. , two insert-type square vertical fiber filter cloths 701 (referred to as filter cloths) on the reverse side are filtered and enter the interior of the filter unit 7, flow out from the water outlet hole at the bottom of the square filter frame 702, and then flow into the clean water through the water outlet hole on the bottom plate 8 Area B, after that, pass through the clean water channel 17 on the partition wall 18 below the water bottom plate 8 to reach the clean water pool D at the rear of the partition wall 18. The clean water in the clean water pool is accumulated to a certain height, and passes through the weir plate 10 from Clean water outlet 11 places flow out.

The suspended matter SS is blocked by the filter unit and left on the filter cloth. After the set time of the equipment is reached, the driving device starts to drive the water collection assembly 2 and the backwash branch assembly 4 to run together. The backwash mechanism and the bottom mud suction mechanism move, and the backwash pump and bottom mud suction pump work to perform backwash and bottom mud suction on the filter unit.

There are several mud suction holes on the backwash branch pipe, and through these mud suction holes, as well as the suction of the backwash pump, the suspended solids that are blocked outside the filter cloth and adsorbed on the filter cloth are reversely sucked (that is, backwash) Into the backwashing branch pipe, go to the backwashing water collection pipe through the steel wire hose, then flow into the sewage ditch 16 through the backwashing pump and the sewage pipe, and discharge from the sewage outlet 12. During backwashing, the vertical fiber filter cloth filter is normally filtered.

Through free sedimentation and sweeping, the sludge scattered and accumulated on the bottom plate 8 of the water is sucked by the bottom mud pump, and then passed through the bell mouth of the suction bottom mud, the suction bottom mud pipe, the steel wire hose 2, the bottom mud water collection pipe, the suction bottom mud Bottom mud pumps and sludge pipes flow into the sewage channel 16 and are discharged from the sewage outlet 12.

The sludge that has passed through free sedimentation and the sludge that has not been sucked clean on the water bottom plate is concentrated in the bottom mud pit 23 below the water bottom plate position in the filter tank, and further concentrated into the sludge discharge port 13. When the bottom When the sludge in the sludge pit 23 accumulates to a certain amount, the sludge discharge port 13 is opened to discharge the sludge at the bottom.

When the water collection assembly 2 drives the backwash branch pipe assembly 4 to walk to the position of the travel switch baffle 22 located at both ends, the travel switch sends a signal to the control cabinet to control the drive motor 9 to reverse, and drives the water collection assembly 2 to turn around and run in the opposite direction . When the water collection assembly 2 drives the backwashing branch assembly 4 to move back and forth along the length of the filter unit 7, the linear sweeping task on the surface of the entire filter layer is completed, and the drive system, backwashing mechanism and sediment suction mechanism immediately outage.

With the extension of the filtration time, the interception capacity of the filter cloth increases, and the filtration resistance increases, causing the water level in the filter to rise. When the water level in the filter tank monitored by the liquid level sensor 14 installed on the tank body reaches a certain set height, it means that the filter cloth needs to be cleaned. At this time, the liquid level sensor 14 sends an induction signal to the control cabinet to control the backwash pump 301 and the bottom sludge suction pump 302 to start, the backwash mechanism and the bottom sludge suction mechanism start to work, and at the same time, the driving device is also started to drive the water collection assembly 2. Walk together with the backwash branch pipe assembly 4, that is, drive the backwash branch pipe 402 close to the blanket-like braid (filter cloth) on both sides of the filter unit 7, and the bottom mud suction branch pipe 403 close to the backwash branch pipe 402 to move together. The backwash water passes through the blanket-like woven fabric (filter cloth) from the inside to the outside, together with the sludge adsorbed on it, passes through the suction holes on the backwash branch pipe 402 and the backwash branch pipe 402, and is taken away by the backwash pump 301. And the sludge that free sedimentation and sweeping are scattered all concentrates on the bottom plate 8 of the water, and is taken away by the bottom mud pump 302 by suction bottom mud bell mouth 405, suction bottom mud branch pipe 403. When the water collection assembly 2 drives the backwash branch pipe assembly 4 to walk to the position of the travel switch baffle 22 located at both ends, the travel switch sends a signal to the control cabinet to control the drive motor 9 to reverse, and drives the water collection assembly 2 to turn around and run in the opposite direction . When the water collection assembly 2 drives the backwashing branch assembly 4 to move back and forth along the length of the filter unit 7, the linear sweeping task on the surface of the entire filter layer is completed, and the drive system, backwashing mechanism and sediment suction mechanism immediately outage.

Driving device, backwash pump and sediment suction pump start conditions: Generally, the drive and pump start after the time set by the equipment is reached by default. In addition, the water level in the filter tank can be monitored by the liquid level sensor 14 installed on the tank body. If the set time is not reached, but when the liquid level sensor 14 detects that the water level reaches a certain set height, the driving device, backwash pump, etc. and the suction sediment pump will also start.

Driving device, backwash pump and sediment suction pump outage conditions: generally, when the water collection assembly 2 drives the backwash branch assembly 4 to complete a back and forth operation, and completes the linear sweeping task on the surface of the entire filter layer, the travel switch An induction signal is sent to the control cabinet, the drive system, the backwash pump and the bottom sludge suction pump stop working, and the backwash mechanism and the water collection assembly 2 stop working immediately. However, when the liquid level is lower than the set height, the drive unit, backwash pump and bottom sludge suction pump will also stop running.
