Description
Technical field
The utility model belongs to titanium white production technical field, is specifically related to a kind of titanium pigment waste acid filtration unit.
Background technology
Titanium White Production By Sulfuric Acid Process is for raw material with titanium slag and ilmenite, use sulfuric acid as carrier in production process, ilmenite is decomposed, sulfuric acid used is separated with titanium dioxide in washing post, washing step can produce a large amount of acid waste water, these acid waste water complex chemical composition, belong to Hazardous wastes, recycle after needing process.But adopt at present general intermediate processing to be difficult to the suspended substance in spent acid to precipitate, existing sedimentation device effect of settling difference and easily blocking.
Utility model content
The purpose of this utility model is to provide a kind of titanium pigment waste acid filtration unit, can cross the most suspended substances filtered in titanium pigment waste acid.
The utility model is achieved by the following technical solution:
A kind of titanium pigment waste acid filtration unit, comprise spent acid storage tank, strainer and Clear liquid tank, its special character is: described spent acid storage tank is connected with two strainers of connecting by pump, and strainer is connected with Clear liquid tank; Described filter interior is equipped with the high suspension medium bead of 0.4-0.6m, and this suspension medium the small ball's diameter is 1-2mm, and filter inlet is positioned at the bottom of suspension medium bead, and filter outlet is positioned at the top of suspension medium bead, and strainer bottom is provided with flase floor; Described filter bottom is inverted cone-shaped, and outlet at bottom is connected with metatitanic acid basin, is provided with whipping appts in this metatitanic acid basin.
Titanium pigment waste acid filtration unit of the present utility model, described strainer adopts the oxidation resistant glass reinforced plastic of acid-fast alkali-proof to make, heatproof 65 DEG C.
Titanium pigment waste acid filtration unit of the present utility model, the suspension medium bead in described strainer adopts macromolecular material to make, and its density is 0.08-0.12g/cm
3, the resistance to organism of bead and oxidant contamination, operational process need not be changed, and annual interpolation is a little, cost-saving.
The beneficial effects of the utility model are: the utility model is filtered titanium pigment waste acid continuously by two strainers; in clear liquid, the concentration of suspension of titanium pigment waste acid can drop to below 30mg/L; the concentrated solution filtered out enters metatitanic acid basin and recycles; at utmost realize the utilization of resources of spent acid; cost-saving, protection of the environment.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structural representations of the utility model strainer.
In figure, 1 spent acid storage tank, 2 strainers, 3 Clear liquid tank, 4 metatitanic acid basins, 5 pumps, 6 whipping apptss, 7 suspension medium beads, 8 flase floors, 9 filter inlet, 10 filter outlets.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The titanium pigment waste acid filtration unit of the present embodiment, comprise spent acid storage tank 1, strainer 2 and Clear liquid tank 3, spent acid storage tank 1 is connected with two strainers of connecting 2 by pump 5, strainer 2 is connected with Clear liquid tank 3, the high suspension medium bead 7 of 0.4-0.6m is equipped with in strainer 2 inside, this suspension medium bead 7 diameter is 1-2mm, filter inlet 9 is positioned at the bottom of suspension medium bead 7, filter outlet 10 is positioned at the top of suspension medium bead 7, strainer 2 bottom is provided with flase floor 8, in inverted cone-shaped bottom strainer 2, outlet at bottom is connected with metatitanic acid basin 4, in this metatitanic acid basin 4, whipping appts 6 is installed.
Producing Titanium Dioxide line washing step produces spent acid and pumps into spent acid storage 1, strainer 2 is squeezed into again from spent acid storage tank 1 pump 5, this the present embodiment two strainers 2 are connected and are used, flocculation agent polyacrylamide is added in strainer 2, strainer 2 adopts whole glass steel to make, acidproof, alkaline-resisting, anti-oxidant, general heatproof 65 DEG C.The suspension medium bead 7 of strainer 2 inside adopts macromolecular material to make, and its density is 0.08-0.12g/cm
3, suspension medium bead 7 is uniformly distributed in strainer 2, close-packed arrays, and absorption retains suspended substance in spent acid, forms cake layer at dielectric surface.Along with cake layer is thickening, gravity is greater than buoyancy, then drop and enter the concentrated liquid zone of bottom back taper.The resistance to organism of spherical medium and oxidant contamination, operational process need not be changed, and annual interpolation is a little.
Spent acid carries out continuous filtration through two strainers 2 can filter out most suspended substances, the clear liquid overflow filtered out is entered in titanium workshop Clear liquid tank 3, wherein in clear liquid, concentration of suspension is 20mg/L, the concentrated solution filtered out enters in metatitanic acid basin 4, for washing step in titanium white production after being mixed with metatitanic acid by whipping appts 6.Open the valve of bottom when strainer 2 cleans, the clear liquid on strainer 2 top freely flows down and cleans bottom thickening filtration medium, simple to operate.
