Description

A kind of radial-flow air supporting machine
Technical field
The utility model relates to a kind of air supporting machine of the usefulness of disposing of sewage, particularly a kind of radial-flow air supporting machine.
Background technology
Existing air supporting machine comprises dissolving, air supporting machine jar body etc., its principle of work is to pressurize in dissolving by water, gas, forming molten gas-liquid sends in the air supporting machine internal reactor by pipeline and mixes with sewage, the rotation of generation eddy current, after sewage and molten gas-liquid and the abundant hybrid reaction of medicament, produce the flocculation ingot simultaneously and be suspended in the sewage.By the tiny microbubble in the molten device liquid, suspended substance supporting in the water to topmost surface,, is discharged by the pot bottom blow-off line to pot bottom formation sludge blanket greater than the heavy foreign material natural subsidence of water proportion.Solute in the sewage is flocculated into crystal take away after, sewage progressively becomes clearly.By the clear water reflux line in the tank body, clear water is delivered in the clean water basin again.Upper strata mud scum silica frost is scraped slag by mud scraper and is flowed in the dirt discharge groove, handles the back outward transport finally by crossing deslimer.This air supporting machine has the following disadvantages:
1, the individual layer tank body can't be isolated combined sewage reaction zone and clear water zone.Existing eddy current air supporting machine equipment is steel construction individual layer tank body, can't isolate combined sewage reaction zone and clear water zone, and the clear water after causing handling mixes with hybrid reaction district sewage secondary in the sinking reflux course, can't reach desirable effluent quality requirement; When clear water refluxes at jar inner bottom part return line, the sedimentation water that contains suspended substance microparticle, heavy substance, flocculation agllutination crystal, when in the process of sedimentation, also not being deposited to mud district, bottom, together sucked by the clear water return line, be incorporated in the clear water of backflow, have a strong impact on the effluent quality after the water treatment of air supporting machine.
When 2, power is scraped the mud scum silica frost, contain the suspended substance microparticle in the backflow clear water.When the mud scum silica frost is scraped at power in the equipment upper strata, because the body refuse of scum silica frost mud flocculation agllutination collection is very easily broken, power is scraped slag stirring rear section mud scum silica frost flocculation piece and is broken, be dissolved in again after the decomposition and form the flocculation particle that suspends in the water in former the pouring water again, clear water secondary after the text-processing is mixed, effluent quality is affected.
3, the ball float control device on the dissolving is how much to control the interior air input of dissolving.Owing to can't differentiate the liquid level actual situation of controlling in the dissolving, often cause jar phenomenon of interior full gas aneroid, so just forming gas directly enters in the big jar of reactor, reactor can not get rational liquid, gas, water proportioning ratio, very easily cause aqueous vapor boiling in the air supporting machine jar, mix water quality, make the failure of air supporting machine water treatment effect, and the debugging of having to start shooting again brings operation problem for normal operation work.
4, the not smooth phenomenon of the stifled groove of part mud scum silica frost is arranged in the air supporting machine mud drainage slot: because the mud groove adopts the poly-low spoil disposal of the high right low mud scum silica frost entire body in a left side, it is big to blow in the groove mud scum silica frost concentration during power spoil disposal, the mud scum silica frost is the flow process distance in mud drainage slot, the residence time is long, be difficult to quick emptying, the mud scum silica frost stifled groove that happens occasionally in groove is not smooth.
Summary of the invention
The utility model is at above-mentioned the deficiencies in the prior art, the isolation that a kind of novel structure is provided, has used easy to operate, energy-conserving and environment-protective, can solve clear water zone and combined sewage reaction zone effectively, high efficiency, the effective a kind of radial-flow air supporting machine of scrubbing.
The technical solution of the utility model is: a kind of radial-flow air supporting machine, comprise molten vapour-liquid jar, the air supporting machine jar body, it is characterized in that: described air supporting machine jar body is double-deck cylinder shape, interior tank body is opened type up and down, be upright in the top of main tank body, interior tank body is connected by channel-section steel with main tank body, between be the sludge settling district, welded top at interior tank body has mud drainage slot, described mud drainage slot is the two ends height, middle low, poly-Chinese style, rectangle, there was outer discharge pipe at the place during the mud trench bottom was poly-, was provided with the conical mixing reactor of handstand in the bottom of main tank body, and the mixing reactor bottom outside has the negative area to prevent bank protection; Described molten vapour-liquid jar is the two round end tank bodies of the elongated of erectting, and comprises molten vapour-liquid tank body, ball float control automation, and molten vapour-liquid enters mixing reactor by molten vapour-liquid pipeline.
Further, the outer setting of described main tank body has the pipeline that is communicated with sump pump, dosing pump, rising pipe.
Further, the material of described air supporting machine jar body is carbon steel sheet or stainless steel plate.
The utility model has the advantages of and be: novel structure, the isolation of using easy to operate, energy-conserving and environment-protective, having solved clear water zone and combined sewage reaction zone effectively, good sewage processing effect, through test of many times, the waste water COD clearance reaches 60%, and the ss suspended solid clearance reaches 95%.
