Description

A kind of lime slaking chemicals dosing plant
Technical field
The present invention relates to water-treatment technology field, particularly a kind of lime slaking chemicals dosing plant.
Background technology
Existing lime slaking dosing typically uses following two modes:One is that refined lime is hung into milk of lime by warehouse to prepare Groove, is made the lime milk solution that concentration is 20%, then with pump defeated milk of lime deliver to waste acid, one section, two sections, three sections of neutralization chambers enter Row is neutralized.Two is that the refined lime of refined lime tank is delivered into Calcified pond by the spiral of refined lime tank, and refined lime connects in pond with water Immersion is touched, natural cooling grabbed to intermediate bin with grab bucket, be washed with water and enter lime slaking machine afterwards for a period of time, finally by slagging tap Spiral carries out the separation of lime mud and milk of lime, and milk of lime is sent to neutralization chamber and is neutralized, and lime mud falls in slag bucket, periodically uses Automobile is transported;Or the refined lime of refined lime tank is formed into lime white, lime by the first elephant trunk into the tank diameter stirring that adds water Slurry again through the second elephant trunk enter lime white sedimentation basin precipitation, the milk of lime on sedimentation basin upper strata through screen filtration, into milk of lime pond, Milk of lime in milk of lime pond is sent into neutralization chamber to be neutralized, the lime mud in lime white sedimentation basin is periodically through digging machine or craft Clear out, transported with automobile.
The content of the invention
The purpose of the present invention is the above-mentioned deficiency for overcoming prior art, and it is high to provide a kind of lime utilization rate, is raised without lime Dirt, the low lime slaking chemicals dosing plant of lime mud water content.
The technical scheme is that:A kind of lime slaking chemicals dosing plant, it includes:Lime delivery unit, lime slaking Unit, milk of lime separative element and lime dosing unit;Wherein, lime delivery unit, the quick lime in refined lime tank is sent To the charging aperture of lime slaking unit;Lime slaking unit, including cylinder, cylinder are provided with charging aperture and discharging opening, in cylinder Portion is divided into from charging aperture to discharging opening:Buffering area, homogeneous area, newborn slag Disengagement zone, Lao Zha areas dreg discharging area;Quick lime is by stone Into milk of lime sand aqueous mixtures, discharging opening stream of the milk of lime sand aqueous mixtures from lime slaking unit after ash digestion unit digestion Go out;Milk of lime separative element, the milk of lime sand aqueous mixtures that will be flowed into from discharging opening are separated into milk of lime and lime mud;Milk of lime Neutralized in neutralization chamber by pump to lime dosing unit.
The technical scheme of an of the invention step is:Described lime delivery unit is spiral conveyer.
The technical scheme of an of the invention step is:Described milk of lime separative element is Spiral sand-water separator, and it includes sand Water separating tank and spiral transferring sand launder;Milk of lime sand aqueous mixtures from lime slaking unit are separated into stone by girt-water separation groove Grey breast and lime mud, milk of lime flow to milk of lime pond;Spiral transferring sand launder, the lime mud that will sink to bottom land is defeated by spiral transferring sand launder It is sent to the outlet at the top of spiral transferring sand launder, Pai Xiangchuzha areas.
Further technical scheme is the present invention:The helical axis of described spiral transferring sand launder is with the horizontal 25 ° of angle.
Present invention beneficial effect compared with the prior art is:1st, because the present invention obtains stone using common quicklime slaking Grey breast, obtains milk of lime, cost-effective more than 20% using refined lime digestion compared with the prior art.
2nd, due to the quick lime in refined lime tank to be directly delivered to the charging of lime slaking unit by spiral conveyer Mouthful, lime airborne dust is greatly decreased, reduce injury of the lime airborne dust to operator's health.
3rd, due to that using Spiral sand-water separator slagging-off, in milk of lime sand mixture 95% lime mud can be separated, Improve quick lime utilization rate more than 10%.
