Description

A kind of pressure type air-float filtration purifier
Technical field
The utility model belongs to water treatment field, relates to a kind of air-float filtration purifier.
Background technology
Pressure filter is a small-sized water treatment system equipment commonly used, and its advantage is to work under pressure in the filter tank, and filter back water has certain pressure can satisfy the requirement of subsequent treatment process head, need not second lift.The tradition air flotation pool generally all is to rely on the run by gravity operation under normal pressure, if the back connects pressure filtering process, the air supporting water outlet enters the pressure type filter tank with regard to needing to promote once more, has so just wasted the part energy.When dissolved air water when being more special oxidizing gas such as ozone etc., open air flotation pool, residual gas that overflows such as ozone also inconvenience are collected and are handled, and environment is polluted.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of pressure type air-float filtration purifier is provided ,Simple in structure, have certain interior pressure in the device, can realize that air supporting and pressure type filter two kinds of water-purifying process.
To achieve these goals, the technical scheme that the utility model provides is as follows: a kind of pressure type air-float filtration purifier, apparatus main body mainly reaches the upper cover and the lower cover of fixedlying connected with it by straight tube and constitutes, the upper cover top is provided with a mud discharging mouth, and residual cake valve and vent valve are installed on the mud discharging mouth pipeline; In the straight tube central tube is installed, central tube has horizontal aperture, in the straight tube in below, horizontal aperture filtration unit is installed, and the central tube bottom is communicated with water inlet pipe, and water inlet pipe passes straight barrel and is communicated with former water; The lower cover bottom is provided with an effluent pipe mouth.
Described central tube adopts the cylinder of the awl end and band loam cake, on the barrel of cylinder loam cake one end, opens some horizontal apertures along circumference.
Described filtration unit adopts on the filter plate stacks filtrate, and filter plate separates straight tube and lower cover.Described filter plate adopts joins the filter plate of filtering cap.
Described lower cover adopts the ellipse end socket, offers a backflow mouth of pipe on the effluent pipe mouth, and the backflow mouth of pipe is communicated with air-dissolving apparatus by return line.
Described air-dissolving apparatus adopts air dissolved pump or dissolving.
Described upper cover adopts awl bucket type end socket.
Described upper cover inner top is equipped with a liquid level switch.
The dissolved air water that the utility model device can be provided by air dissolved pump or dissolving, when dissolved air water pressure is higher than into water and device operating pressure 0.3MPa when above, dissolved air water just can discharge microbubble, in central tube (zone of action), adsorb mutually with the water inlet solid particulate, enter and float behind the straight tube (disengaging zone) and gather in the upper cover awl bucket of container top, regularly open slag-discharging valve and discharge scum silica frost.Water after the air supporting along the disengaging zone downwards after filtration the bed of material filter.Backwash water inlet or backwash air inlet enter container by water outlet during the filter material layer backwash, are upwards discharged by mud discharging mouth through filtering layer.At awl bucket end socket top a liquid level switch is set, when awl bucket end socket has gas accumulation, gas is discharged by its control awl bucket residual cake valve.
The utility model has the advantages that on air supporting and filtration process bonded basis, by suitable increase equipment operating pressure, air-float technology and pressure type filtration process can be moved in same device, in addition by device top slag bucket deslagging, to replace traditional slag scraper, simplify the dreg removing system of air-floating apparatus, be convenient to the residual gas collection and treatment.The utility model moves air supporting and filtration process in certain pressure, can be subsequent technique certain overbottom pressure is provided, and reduces to promote number of times, simplifies dreg removing system, makes operational management convenient.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model apparatus structure and operation are described in detail:
A kind of pressure type air-float filtration purifier as shown in Figure 1, apparatus main body mainly reaches the upper cover 5 and the lower cover 15 of fixedlying connected with it by straight tube 13 and constitutes, upper cover 5 adopts awl bucket type end socket, the top has mud discharging mouth 8, residual cake valve 6 and vent valve 7 are installed on the mud discharging mouth pipeline, and the upper cover inner top also is equipped with a liquid level switch 9; In the straight tube 13 central tube 11 is installed, central tube 11 adopts the cylinder of the awl end and band loam cake, the barrel upper edge circumference of cylinder loam cake one end is offered some horizontal apertures 10, in the straight tube in 10 belows, horizontal aperture filtration unit is installed, filtration unit adopts to join stacks filtrate 12 on the filter plate 14 of filtering cap, filter plate 14 separates straight tube and lower cover, the central tube bottom is communicated with water inlet pipe 4, water inlet pipe 4 passes straight barrel and is communicated with former water, chemical feed pipe 2, line mixer 3 and air-dissolving apparatus 1 are arranged on the pipeline between former water and the water inlet pipe mouth successively, and air-dissolving apparatus 1 adopts air dissolved pump or dissolving; Lower cover 15 adopts the ellipse end socket, and the lower cover bottom is provided with an effluent pipe mouth 16, offers a backflow mouth of pipe on the effluent pipe mouth 16, and the backflow mouth of pipe is communicated with air-dissolving apparatus by return line.
Former water is added by chemical feed pipe and enters line mixer behind the coagulating agent and carry out the thorough mixing reaction during operation, forms floc particle.At this moment add the dissolved air water that air-dissolving apparatus (air dissolved pump or dissolving) provides, keep dissolved air water pressure greater than more than the water inlet 0.3MPa, dissolved air water will discharge microbubble after adding.Enter central tube by the equipment water inlet pipe then floc particle and microbubble are adsorbed mutually, advance straight tube (disengaging zone) by central tube lateral aperture saliva advection.Float to upper cover awl bucket top this moment on the scum silica frost, can regularly open residual cake valve and discharge, and enter filtering layer under the current direction, enter lower cover through filter plate and discharge by rising pipe by mud discharging mouth.Rising pipe links to each other with air dissolved pump, provides recirculation water to device.
