Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1, it is structural representation of the present utility model, the turbulence washing tower of a kind of cleaning fluid reusable edible of the utility model, comprise tubular tower body 1 and cleaning solution circulating device, liquid storing section 2 is from bottom to top integrated with in described tower body 1, air inlet section 3, dumped packing section 4, liquid column-spraying section 5, packing section 1, spray section 1, packing section 28, spray section 29 and demist section 10, wherein liquid storing section 2 is provided with the beds of precipitation 11, sewage draining exit 12 and circulating cleaning fluid outlet 13, air inlet section 3 is provided with gas feed 14, demist section 10 establishes demister, purified gas gas outlet 15 is established at tower body 1 top, described cleaning solution circulating device comprises cleaning fluid supplemental tank 16, circulating pump 17 and cleaning fluid conveying pipeline road 18.
Described dumped packing section 4 upper and lower part establishes upper bearing plate 20 and lower support plate 21 respectively, and the dumped packing that dumped packing section 4 is placed is cascade ring, Pall ring or polyhedron empty ball, and material is PE, PP, PVC, CPVC or PVDF plastics.
Described packing section 1 and packing section 28 have at least one to arrange structured packing, and structured packing is the vertical moire filler of pottery or metal material.
Described liquid column-spraying section 5 establishes liquid column-spraying device, and liquid column-spraying device is made up of liquid column-spraying pipe 24 and fluid column nozzle 25, and liquid column-spraying pipe 24 connects cleaning fluid conveying pipeline road 18, and pressure regulator valve 26 is established in porch.
Described spray section 1 and spray section 29 establish spray equipment, and spray equipment is made up of shower 22 and spray spout 23, and shower 22 connects cleaning fluid conveying pipeline road 18, and pressure regulator valve 26 is established in porch.
The described beds of precipitation 11 are made up of the swash plate of dense arrangement or inclined tube, and its inclination angle is 55 ~ 65 °.
Purified gas gas outlet 15 connects air exhauster, make to produce negative pressure in tower, gas from gas import 14 to be clean enters in tower, under suction function, be full of rapidly air inlet section 3, then enter dumped packing section 4 from bottom to top equably, the upper and lower turbulence under airflow function of lightweight dumped packing rotates and mutually collides, and forms turbosphere.The cleaning fluid carried by circulating cleaning fluid conveyance conduit 18 is upwards sprayed by fluid column nozzle 25, high density is sprayed fluid column and is fully contacted with gas, the drop of gravitational settling with spray liquid and carry out mass transfer and the reaction that secondary has contacted gas-liquid two-phase, and by dumped packing fluidisation, the dumped packing of fluidisation rotates and liquid film constantly broken renewal in collision in turbulence, thus strengthening mass transfer effect.
The gas cleaned through liquid column-spraying section 5 continues upwards to flow, and through two sections of filler spray section, spray spout 23 is fully wetting by filling surface with cleaning fluid, and gas is sailed against the current by filler hole, carries out mass transfer at filling surface gas-liquid two-phase close contact.When liquid flows downward along packing layer, have gradually to the trend that tower wall is concentrated, be called wall flow phenomenon.Wall stream effect can cause gas-liquid two-phase skewness in packing layer, and mass-transfer efficiency is declined, and conventional filler spray column is because packing layer is higher, and need to carry out segmentation, centre arranges apparatus for redistributing.And the utility model is because hypomere has established liquid column-spraying section 5, packing layer only can be divided into two sections, and centre need not arrange apparatus for redistributing.
Through scrubbing tower purified gas with mist, be wherein dissolved with harmful substance, also easily cause staining and heavy corrosion of blower fan, heat exchanger and flue etc., therefore Purge gas needs demist before leaving scrubbing tower.The demister arranged by demist section 10 makes mist form large drop to separate from purify air, can improve operating condition, Optimization Technology index, reduces equipment corrosion, extension device service life, and can reduce atmosphere pollution.
Swash plate (inclined tube) sedimentation basin is the efficient combined-type sedimentation basin designed according to shallow pond sedimentation theory, tube settling water purification is swash plate (inclined tube) assembly installing certain inclination angle above impurity superposed layer, the flco alum making the suspension in water, solids or formed after dosing coagulant, thin mud layer is accumulated at inclined tube bottom side surface, rely on Action of Gravity Field to sink to sludge hopper to arrange outward, top clarified solution rises gradually, can directly discharge or reuse.This principle is applied to the liquid storing section 2 of scrubbing tower by the utility model, enable with gas transfer after cleaning fluid efficient, regenerate to high-quality, realize recycling of cleaning fluid.The dirt precipitated by swash plate (inclined tube) is discharged by sewage draining exit 12.
Cleaning fluid after regeneration purification sends into liquid column-spraying pipe 24 and shower 22 by circulating pump 17 through cleaning fluid conveying pipeline road 18, and the main pipe rail before liquid column-spraying pipe 24 and shower 22 nozzle establishes pressure regulator valve 26 rearrange liquids pressure, to reach best spraying effect.When regenerating the cleaning fluid after purification lower than regulation liquid level, supplementing from cleaning fluid supplemental tank 16, ensureing that system cloud gray model needs.
