Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of environment-friendly and energy-efficient self-cleaning reverse filtration device.
Background technology
Filter refers to plant equipment or the device for filtering, and is common apparatus common in industrial production.Dirt is trapped through the filter screen of filter, carries out subsequently surface filtration, cake filtration and in-depth filtration.Material filling type deep-bed filter is large because of separate unit treating capacity, good water permeability, and processing accuracy can meet filth disposal index, is therefore used widely.
Filter by overcurrent to being divided into forward filter, reverse filtration, Transverse to several forms such as filtration and forward and reverse filtrations.Wherein, forward filter is main traditional mode, there is following problem: 1. forward filter device used after a period of time, due to the obstruction of interception pollutant, the comprehensive functions such as pressure reduction when filtrate deadweight, filtration, often make filtrate extruding adhesion, easily forming filtrate hardens, cause filtering water to decline gradually, can not meet oil-field flooding requirement, within every 1 ~ 2 year, need to change 1 filtrate; 2. for reaching effective backwash rate, backwash water consumption is large, processes water use efficiency lower, causes operating cost to increase; 3. forward filter must be shut down backwash, and impact is produced, and often needs an identical device for subsequent use simultaneously for overcoming this problem, has virtually increased manufacture and administrative expenses.
Utility model content
Use after a period of time for the forward filter device of traditional mode, due to the obstruction of interception pollutant, the effects such as pressure reduction when filtrate deadweight, filtration make filtrate extruding adhesion, formation filtrate hardens, cause filtering water to decline gradually, can not meet the present situation of filth disposal requirement, the utility model application suspension bed reverse flow work principle of filter provides a kind of environment-friendly and energy-efficient self-cleaning reverse filtration device.
The utility model solves the technical scheme that its technical problem adopts: a kind of environment-friendly and energy-efficient self-cleaning reverse filtration device, is mainly made up of housing, filtrate, air supply system, silt box, air compressor machine, sand-washing device and sand extraction tube; Described silt box, adopts elbow structure, is made up of, and is provided with air inlet pipe and filling pipe in described fairlead control valve, appearance arenaceous shell body, air inlet pipe, nozzle, fairlead, filling pipe, at the upper surface horizontal flange place of silt box, clamps control valve; Described sand-washing device, adopts twin-tub structure, is mainly made up of standing chamber, collection tank, sand washing tube, agitator, spiral slide cone, oil blocking cover and ball float, and is provided with self-poking arrangement in described sand-washing device; Described air supply system is mainly made up of air compressor machine and air accumulator.
Sand washing tube, it comprises urceolus and inner core, it is characterized in that described urceolus top is provided with two exhaust outlets; Described collection tank is provided with flashboard; Described spiral slide cone invests inner core inwall.
Sand extraction tube is the sebific duct that sand-washing device is communicated with sand trap, is communicated with in lower end by tracheae with air accumulator simultaneously; And be provided with a flow control valve in the middle of described sand extraction tube, be spiral outward up at housing wall, sebific duct is divided into three sections, middle with putting forward sand joint serial connection.
Silt box entirety adopts elbow structure, can prevent that the gravity of filtrate entirety from directly acting on nozzle place, causes the filtrate of pollution near nozzle, to form obstruction, while causing air lift filtrate cannot on carry.In fairlead, be provided with air inlet pipe and filling pipe, it can concentrate the kinetic energy of air-flow to be delivered in needs the sand of carrying to roll into a ball above, increases the up motion energy of sand grains, and filling pipe is given up sand group increase mobility, and the while is sneaked into the layer of sand of pollution as rinse water, assist to clean.Fairlead outlet leaves suitable spacing with nozzle inlet, is the important measures that prevent obstruction.At the upper surface horizontal flange place of silt box, clamp the control valve that can adjust arbitrarily aperture, major function is to adjust the sand amount of leaking, and also has choke preventing function simultaneously.
The setting of the self-poking arrangement of sand-washing device, has promoted backwash intensity greatly, uses dexterously to carry sand impact of water and make agitating device spinning; Adopt twin-tub structure, the relative stratification of high oil-polluted water of being convenient to wash out, effectively separates.The set adjustable spilling water height of flashboard on collection tank, controls and washes out quantity of wastewater effluent, and backwash water enters outer comb after collecting.Spiral slide cone invests sand washing tube inwall, can delay the speed that filtrate falls, and filtrate slides in its mantle friction simultaneously, has the function of washing by rubbing with the hands.Oil blocking cover is mainly used in collecting micro-oil droplet in up clear water, and the micro-oil droplet that has little time floating while simultaneously preventing sand-washing device backwash enters clear water zone.Unique agitating device, under blade shear action, cleans to filtrate the vital effect of having played.
Air supply system is mainly made up of air compressor machine and air accumulator, and described pneumatics function is given air accumulator ftercompction automatically according to the pressure high-low limits of setting.
The utility model, a kind of environment-friendly and energy-efficient self-cleaning reverse filtration device operation principle is: application suspension bed reverse flow work principle of filter, integrated application micro flocculating filter technology and gas-solid-liquid Fluidization Engineering backwash technology.This device, operation can be divided into raw water filtration and two relatively independent processes of simultaneously carrying out again of filtrate cleaning and regeneration, and the two completes at the different passages of same filter.The former former hydrodynamic force relies on high potential difference or pump to promote, and latter completes by compressed air.Filter process is that former water enters cloth water ring from water inlet, by the energy dissipating effect of cloth water ring, up from the gap between cloth water ring and sliding cone, by suspended filter material layer.Filtrate is held back absorption and machinery interception to suspended impurity in water.After filter, water upwards passes filtering layer, between oil blocking cover and tank inwall, is advanced into Rinsing Area, finally discharges from delivery port.
Filtrate cleans and utilizes the high velocity air that air supply system provides to drive the water body of sand developing tube upwards to move, and filtrate, under the drive of water body negative pressure, is constantly sucked into sand developing tube from silt box nozzle, is finally transported in the sand-washing device on top.In sand developing tube, aqueous vapor upwards rapid movement forms turbulent flow, can tentatively wash away and rinsing a filtrate surperficial dirt of material.In sand-washing device, then clean through mechanical agitation wherein, clean filtrate drops to filtering layer, and the sewage washing out is discharged from the dirt discharge groove being communicated with sand-washing device side, and gas discharges from sand-washing device upper end exhaust outlet.
The utility model, a kind of environment-friendly and energy-efficient self-cleaning reverse filtration device, have control simple, energy consumption is low, backwash water is few; can realize backwash long-term filtration in non-stop-machine situation, filtrate does not harden, and need not change; long service life, has advantages of that conventional filter is incomparable.
