Abstract
The utility model discloses a two-phase flow flushing device. The two-phase flow flushing device comprises a filter and a flushing pipeline, wherein the flushing pipeline is connected to the water outlet end of the filter; an air inlet is formed in the flushing pipeline; water flow in the pipeline and air flow entering the pipeline form air-liquid two-phase flow for flushing a filter element or a filter screen in the filter forwardly or backwardly; a sewage discharging outlet is formed in the filter and is used for discharging flushed impurities. During flushing through the two-phase flow flushing device, when bubbles and the water flow in the two-phase flow move and pass through filter holes, the bubbles are continuously broken under the combined action of micro-particles of the filter element and the water flow; by virtue of impact force formed by breaking of the bubbles, the impurities adsorbed to the surface of the filter element fall off, so that the filter is thoroughly flushed. The two-phase flow flushing device has the advantages of reasonable structure, good flushing effect and the like.
Description
Technical field
The utility model discloses a kind of two phase flow flusher, by International Patent Classification (IPC) (IPC), divides and belongs to filter manufacturing technology field.
Background technology
Filter, be that a kind of filter screen that utilizes is directly tackled the impurity in water, removes water body suspension, particle; reduce turbidity; purify water, reduce the generations such as system dirt, bacterium algae, corrosion, with the precision equipment purified water and other equipment of protection system work.During work, former water or sewage are entered by entrance, after net filtration, by pure water inlet, are discharged after filtration, in filter process, filter screen builds up foul, the impurity in water, forms the impurity screening layer, and this impurity layer is deposited in the inboard of filter screen, affect filter effect, need to often clean; During cleaning, general using water, through water purification passage reverse operating, is cleared up the impurity layer purpose thereby reach.In fact, the water yield that anti-washing and cleaning operation needs is large, causes water resource waste, and in addition, aperture of filter screen is little, and only water rinses not thorough.
China document CN201310049683.5 discloses the purging method of a kind of inner pressed milipore filter and flusher, flusher comprises flushing pipe and flushing water switch, sewer pipeline and sewer switch, also comprise air accumulator and aspirating pipeline, and be located at the aspirated switch on described aspirating pipeline, described aspirating pipeline is connected in the water inlet of filter core, in document, air inlet and flushing water are reverse converging, be that flushing water is entered by the water purification mouth, and gas is entered by former water inlet, the part air-flow is directly discharged by sewage mouth.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of two phase flow flusher, adopts biphase gas and liquid flow to be rinsed filter, reaches the purpose that developing result is good, economize on water.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of two phase flow flusher, comprise filter and flushing pipe, flushing pipe is connected to the water side of filter, flushing pipe is provided with air intake, current in pipeline and the air stream entered form biphase gas and liquid flow filter core or the filter screen in flush filter forward or backwards, and described filter is provided with the impurity of sewage draining exit after with the discharge backwash.
Further, described filter is provided with water inlet and delivery port, be provided with former water stop valve at corresponding inlet channel, outlet conduit is provided with the water outlet stop valve, water inlet wherein or delivery port are the flushing pipe entrance simultaneously, be provided with the flushing stop valve on flushing pipe, the air intake of flushing pipe connects air duct and is provided with air cutoff valve.
Further, described air duct connecting fan or air compressor etc. have pressurized air source so that the air stream in two phase flow to be provided.
Further, the negative pressure that the backwashing water flow at high speed in described flushing pipe produces forms biphase gas and liquid flow by extraneous air intake.
Further, the flushing water in described flushing pipe, at a high speed by sudden turn of events cross section, forms cavitation in part, produce bubble and form biphase gas and liquid flow.
When the utility model is rinsed, when the bubble in two phase flow and water movement process filter opening, under the acting in conjunction of the molecule of filter core and current, bubble constantly breaks, the impulsive force that bubble eruption forms, the impurity of cartridge surface absorption is come off, realize the cleaning down to filter, there is the advantages such as rational in infrastructure, that developing result is good.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1, a kind of two phase flow flusher, comprise filter 1 and flushing pipe 2, flushing pipe 2 is connected to the water side of filter 1, flushing pipe 2 is provided with air intake, current in pipeline and the air stream entered form biphase gas and liquid flow filter core or the filter screen 100 in flush filter 1 forward or backwards, and described filter 1 is provided with the impurity after sewage draining exit 13 rinses with discharge.Filter 1 is provided with water inlet 11 and delivery port 12, be provided with former water stop valve at corresponding inlet channel, outlet conduit is provided with the water outlet stop valve, water inlet wherein or delivery port are the flushing pipe entrance simultaneously, be provided with the flushing stop valve on flushing pipe 2, the air intake of flushing pipe connects air duct 3 and is provided with air cutoff valve.The air duct connecting fan is to provide the air stream in two phase flow.
As shown in Figure 1, the water of water inlet 11 is provided by water pump, and air is provided by blower fan.Under normal operation, stop valve 402,403,405 is closed, and stop valve 401,404 is opened.Under sewage or former water are driven by water pump, through stop valve 401, the filter core or the screen pack that enter among filter or water tank are filtered, and reach the water standard of middle water after filtration, from delivery port 12, flow out.After filtering a period of time, impurity can be stained with on filter core or screen pack, thereby the obstruction of screen pack may be caused, have influence on the normal operation of whole filtration system, now will just rinse or backwash.
When carrying out backwash, close stop valve 401,404, opening stop valve 402,403,405.The water that water pump provides, after stop valve 402, with the air provided by blower fan, after stop valve 403, is mixed, and forms gas-liquid mixed stream, and screen pack is rinsed, and after rinsing, sewage is discharged by sewage draining exit.
Air of the present utility model and current are for entering in the same way, and except utilizing blower fan, the negative pressure produced in the time of also can utilizing the high speed backwashing water to flow in pipeline, by extraneous air intake, also can have the mode of other generation gas-liquid mixed stream.
The above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
