Description
Technical field
The utility model relates to a kind of Novel filter device adopting air-water backwashing technique, is mainly used in purification of water quality.
Background technology
Conventional middle-size and small-size waterworks floor space is large, complex structure, and the construction period is long, and management expectancy is high, partly replace by Integral steel purifier.Filter last procedure as integrative water purifying device, the quality of operation directly has influence on the effluent quality of water factory.Most of filter uses water backwashing separately, does not often reach the backwash effect of expection, cause aquifer yield to decline within the scope of back washing strength design load, seriously hinders the normal operation of filtering area.Or back washing strength is too high, washing water quantity is large, adds the operating cost of water factory.
Backwash is very large on the impact of filtering area working effect, therefore, is badly in need of a kind of backwashing technology preferably, make filter material layer often be in backwash under optimal conditions, not only can save water and energy, can also effluent quality be improved, increase the retaining power of filter material layer, extend filter cycle.
Summary of the invention
The utility model provides a kind of Novel filter device adopting air-water backwashing technique, effectively can solve the problems such as existing filtering area backwash is thorough, washing water quantity is large, achieve the Automatic Control operation of technical process simultaneously.
For achieving the above object, the utility model is achieved by the following technical solutions: described filter mainly comprises casing, and casing is divided into water distribution layer, filter course and layer three part of catchmenting.Be provided with water inlet, washed-out sand rhone in water distribution layer, washed-out sand rhone is connected with backwash discharge outlet.Be furnished with filter plate in filter course, filter plate is provided with the special filter cap of some air water backwashes and filtrate.Catchment in layer and be provided with delivery port, air inlet and gas distribution pipe, gas distribution pipe is connected with air inlet.
Water inlet is connected with water inlet pipe, and air inlet is connected with air inlet pipe, and delivery port is connected with Graceful water pipe, backwash water inlet pipe, and backwash discharge outlet is connected with backwash drainpipe.
Water inlet pipe, Graceful water pipe, backwash water inlet pipe, air inlet pipe, backwash drainpipe are equipped with electrically operated valve.
Good effect of the present utility model is adopted to be:
1, backwash is effective, and filtering layer retaining power improves 100%, and filter cycle extends 60-70%.
2, wash intensity greatly to reduce, thus decrease the washing water quantity of filtering area.
3, filtering area inlet/outlet pipe is equipped with electrically operated valve, achieves the Automatic Control operation of technical process.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of schematic diagram adopting the Novel filter device of air-water backwashing technique of the utility model;
In figure: 1, water inlet; 2, washed-out sand rhone; 3, casing; 4, filtrate; 5, filter cap; 6, filter plate; 7, gas distribution pipe; 8, delivery port; 9, air inlet; 10, backwash discharge outlet; 12, water inlet pipe; 13, backwash water inlet pipe; 14, Graceful water pipe; 15, air inlet pipe; 16, backwash drainpipe; 11.1-11.5 electrically operated valve.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail
Filter process: open the electrically operated valve (11.1) on water inlet pipe (12), the electrically operated valve (11.3) on Graceful water pipe (14), close electrically operated valve (11.4), the electrically operated valve (11.2) on backwash water inlet pipe (14), the electrically operated valve (11.5) on backwash drainpipe (16) in air inlet pipe (15), filter.
Backwash process: when the system is operated or when operation pressure reduction reaches setting value, enter backwash state.Now, electrically operated valve (11.1) in closedown water inlet pipe (12), the electrically operated valve (11.3) on Graceful water pipe (14), electrically operated valve (11.2) in maintenance backwash water inlet pipe (14), the electrically operated valve (11.5) on backwash drainpipe (16) are in closed condition, first open the electrically operated valve (11.4) in air inlet pipe (15), carry out air purge; After 2 minutes, open the electrically operated valve (11.2) on backwash water inlet pipe (13), the electrically operated valve (11.5) on backwash drainpipe (16), carry out air water and rinse simultaneously; After 4 minutes, close the electrically operated valve (11.4) in air inlet pipe (15), wash, after 6 minutes, electrically operated valve (11.2) in closedown backwash water inlet pipe (13), the electrically operated valve (11.5) on backwash drainpipe (16), complete the backwash process of filtering area.
