The parallel purification of waste water device of a kind of high-efficiency double-layer bed
Technical field
The present invention is used for the larger industry of the reuse quantity of circulating water such as electric power, iron and steel, municipal administration, printing and dyeing, relates to sewage treatment area, particularly relates to the parallel purification of waste water device of double bunk.
Background technology
Along with population constantly increases and economic develop rapidly, water consumption and water displacement increase year by year, and limited water resources is constantly polluted, and the imbalance between supply and demand of water resources is further sharp-pointed.Based on above-mentioned cognition, current industrial effluent reusing is subject to the attention of relevant department day by day, as the second water source newly developed, the reuse of municipal effluent and trade effluent has the advantages that the water yield is large, stable, do not need long distance water diversion, be a kind of reliable water resources.As compared to the method for sea water desaltination with other mining new source of waters such as remote water transfer, industrial effluent reusing less investment, duration short, instant effect, more real easy.The reuse of trade effluent, effectively can keep the running balance of water resources, realize the benign cycle of water, prevent the pollution of the environment, and ensures that industrial development is to the needs of water.Industrial effluent reusing will bring significant economic benefit, environmental benefit and social benefit.
In the industry production process that electric power, iron and steel water consumption are larger, solid particulate can be scattered in system along with the circulation of steam, under certain temperature, pressure and pH value condition, become dissolved impurity.And control the content contributing to reducing solubilised state metal ion as the solid impurity of the main source of dissolved impurity.A considerable amount of iron ion deposits in systems in which and can form underdeposit corrosion, and iron, silicon sequence of ion also can form deposition at steam turbine and the medium/low pressure section of boiler tubing.
It is large that common filter has floor space, and filter effect restricts by various factors, reliable undesirable, realizes full-automatic difficulty, easily produces filtrate caking, the halfway phenomenon of backwash.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide that a kind of floor space is little, treatment capacity is large, filtration efficiency is high, effectively prevent that filtrate from luming, the parallel purification of waste water device of backwash halfway high-efficiency double-layer bed.
For realizing the object of the invention, provide following technical scheme: the parallel purification of waste water device of a kind of high-efficiency double-layer bed, comprise housing, it is characterized in that in housing, being provided with upper and lower two-layer refining plant, levels refining plant includes taper top board, be opened in the water inlet pipe at taper top board center, be arranged at the backwash gas distribution piping below taper top board, porous filter plate below backwash gas distribution piping, be arranged at the filtrate on porous filter plate, catchment piping and blow-down pipe below porous filter plate, the water inlet pipe of described lower floor refining plant stretches out outside housing through the porous filter plate of upper strata refining plant.
As preferably, the taper top board lower surface of upper strata refining plant is provided with some and supports steel pipes, supports that steel pipe bottom is provided with reinforcement gusset.
As preferably, the backwash gas distribution piping of upper strata refining plant comprise supervisor, be responsible for the ring pipe be connected and the some arms be distributed on ring pipe.
As preferably, the backwash gas distribution piping of lower floor's refining plant comprises supervisor, is connected with supervisor and vertically disposed two arms, be responsible for the arm being connected also horizontal-extending.
As preferably, the piping that catchments of upper strata refining plant comprise supervisor and with the octagon circulating line be responsible for use 8 arms of being connected and 8 tube stubs and be spliced into, described circulating line offers gully-hole.
As preferably, the piping that catchments of lower floor's refining plant comprise supervisor, be responsible for two the inc circulating lines be connected, described circulating line offers gully-hole.
As preferably, porous filter plate is circular orifice, is provided with strainer head in hole.
As preferably, housing is separately provided with inspection manhole, long waist visor and discharge opening.
Beneficial effect of the present invention: the present invention adopts the double-deck clean-up bed of right circular cylinder shape cleaner cylindrical shell, parallel-connected operation.Single cover cleaner diameter can reach more than 10 meters, detergent power reach hundreds of cube per hour more than, have superpower detergent power, floor space and construction investment only have the half of general strainer.Mix motorized valve and PLC can carry out full automatic control, all on-the-spot feedback signals are connected with watch-keeping cubicle PLC, can remote online operation supervise and control by HMI, carry out technical parameter setting, realize fault alarm display, system reserves Ethernet interface, by network communication function, can realize data transmission.High-efficiency double-layer bed parallel purification of waste water device is compared with traditional pretreatment unit, and total facility investment expense reduces, floor space is little, the better effects if of purification, shorten the clarification time, decrease operating performance; Long service life, by the hierarchical control suspended substance particle diameter of one-level filtration bed with multi filtration layer, its purification precision is high, and purification there will not be short flow phenomenon, has corrosion-resistant, wear-resisting, heatproof, the life-span is long, adsorptive power is strong, can realize water, gas mixing backwash.Be mainly used in removing Organic substance in water, colourity and chlorine residue in feedwater, disintegrating system in waste pipe.It is large that this invention has treatment capacity, simple to operate, not the feature such as easy break-down, mixes motorized valve and PLC can carry out full automatic control, can extensively adopt in industry-by-industry.
