Description
Technical field
The present invention relates to field of environment protection equipment, particularly a kind of filtering cloth filtering pool back purge system.
Background technology
Existing domestic filter cloth filter ground retains removal by the needle-like nylon fiber hair of filter cloth surface to the solid particle suspended in water, during work, sewage is from a side inflow of fiber filter cloth layer, suspended particulate substance is wherein retained by fiber filter cloth, clear water flows out from filter cloth opposite side, SS≤10mg/L after water outlet, turbidity≤2NTU.During backwash, filter cloth surface is close to by backwash boots, and backwashing pump work produces negative pressure makes needle-like nylon fiber hair trail, and after using part filter, water regenerates filter cloth.But it is good not to the regeneration effect of filter cloth only to use water to rush this single mode in this backwash process, shortening backwashing period energy consumption increases, and after consuming part filter, water adds operating cost simultaneously.Carried out a kind of filtering cloth filtering pool backwash boots research work adopting gas, water hybrid mode for this reason, object be by comprehensive system test, analyze and research solve backwash time backwashing manner single, water after waste filter, increases operating cost problem.
Summary of the invention
The invention provides a kind of filtering cloth filtering pool back purge system, when solving backwash for prior art, backwashing manner is single, and water after waste filter, increases operating cost problem.
Technical scheme of the present invention is as follows:
A kind of filtering cloth filtering pool back purge system, described filtering cloth filtering pool back purge system comprises backwash boots, gas distributionbranch pipe, valve, gas distribution house steward, intake valve, backwash drinking-water pipe and backwashing pump, described backwash boots are connected with backwash drinking-water pipe, described backwash drinking-water pipe is connected with backwashing pump, a gas distributionbranch pipe is respectively provided with up and down inside described backwash boots opening part, described gas distributionbranch pipe is provided with multiple valve, described gas distributionbranch pipe is connected with gas distribution house steward, described gas distribution house steward inlet end is provided with intake valve, air inflow during for regulating backwash, described gas distribution house steward exceeds filter cloth highest working water level.
Described a kind of filtering cloth filtering pool back purge system, its preferred version is be T-shape inside described backwash boots, opening part two ends sidewall is provided with the groove installing gas distributionbranch pipe and valve, described backwash boots opening part is close to filter cloth surface, described backwashing pump makes to produce negative pressure in backwash boots by backwash drinking-water pipe, by pull of vacuum, the fiber of filter cloth surface filter hair is extended a part and enters into backwash boots inside.
Described a kind of filtering cloth filtering pool back purge system, its preferred version is that the air in described valve carries out gas, water associating backwash in backwash boots opening part mixing acting in conjunction to the fiber hair of filter cloth surface with the rear water of filter, and when gas, water associating backwash, gas, water mixed proportion are 2-5:1.
Operation principle of the present invention is as follows: after backwash process starts, and backwashing pump is started working, and makes to produce negative pressure in backwash boots by backwash drinking-water pipe; The opening part of backwash boots is close to filter cloth surface, and the effect due to pull of vacuum makes the fiber of filter cloth surface filter hair extend a part and enters into backwash boots inside; The negative pressure simultaneously brought due to pull of vacuum makes the air in valve and the rear water of filter in backwash boots opening part mixing acting in conjunction in backwash; Regulate intake valve to control air inflow, deficiency of air can connect air pump; Regenerate efficiently the fiber filter hair of filter cloth surface after the mixing of gas, water, the solid suspension that filter cloth surface retains is taken away in the acting in conjunction of being washed away by vibrations and the water of bubble.
Beneficial effect of the present invention: technical scheme manufacture of the present invention is simple, be easy to realize, high-new mixing wastewater with air mode is adopted to carry out backwash to filter cloth, during backwash, gas acts on water along with the negative pressure that backwashing pump work produces enters in backwash boots simultaneously and filters hair to the fiber of filter cloth surface and regenerate, flushing due to water adds that acting in conjunction that the vibrations of bubble and water wash away is taken away the solid suspended particle that filter cloth surface retains and more easily departed from, improve the regeneration effect of filter cloth, when the use introducing water after decreasing filter while gas solves backwash, backwashing manner is single, after waste filter, water problem reduces operating cost simultaneously, the continuous operation ability of raising equipment and reliability.Therefore this structure is adopted to have great Social benefit and economic benefit.
