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%.

Specific embodiment

Detailed construction of the invention is further described below in conjunction with figure and specific embodiment.

As shown in figure 1, a kind of lime slaking chemicals dosing plant of the invention, it includes：Spiral conveyer 2, lime slaking unit 3 And Spiral sand-water separator 4；Wherein, spiral conveyer 2 is arranged on the lower section of refined lime tank 1, by the raw stone in refined lime tank 1 Ash is delivered in the charging aperture 32 of lime slaking unit 3；Lime slaking unit 3, including cylinder 31, cylinder 31 are provided with charging aperture 32 With discharging opening 33, it is divided into discharging opening 33 from charging aperture 32 inside cylinder 31：Buffering area, homogeneous area, newborn slag Disengagement zone, drag for Slag area dreg discharging area；The cylinder 31 of lime slaking unit 3 can gyration under the low speed, quick lime and water in cylinder, due to cylinder The revolution of body and flight are acted on, and are voluntarily stirred in cylinder, are digested by gyration, and the newborn slag of lime slaking unit 3 is separated Area is provided with turn sieve for sieving milk of lime sand aqueous mixtures rotated together with cylinder 31, the milk of lime after turning sieve screening In the Spiral sand-water separator 4 that slag mixture flows into the lower section of discharging opening 33 from discharging opening 33, and the lime mud of bulk stays in cylinder 31 Lao Zha areas dreg discharging area, discharges outside cylinder 31 during deslagging.Spiral sand-water separator 4 is arranged on the top in milk of lime pond, including Girt-water separation groove and spiral transferring sand launder 41, the milk of lime sand aqueous mixtures after screening enter in girt-water separation groove, carry out newborn slag point From milk of lime overflows the spout hole 43 of girt-water separation unit 4, and into milk of lime pond, lime sand sinks to the groove of girt-water separation groove Bottom, the row of 41 top exit of spiral transferring sand launder 42 is transported to by the helical axis for rotating spiral transferring sand launder 41 by lime mud along helicla flute To Chu Zha areas（It is to draw in figure）, because helical axis transports lime mud upwards with the horizontal 25 ° of angles, lime mud was being conveyed Further milk of lime is separated in journey, so as to ensure that the lime mud moisture content of discharging opening is not more than 60%, improves the utilization rate of lime More than 10%, will be neutralized in the neutralization chamber of the milk of lime pump in Calcified pond to lime dosing unit by vertical pump, acid will be contained The accessing pending water of property carries out dosing neutralisation treatment.

General principle of the invention and principal character has been shown and described above, it should be understood by those skilled in the art that, The invention is not limited in any way for above-described embodiment, all technical sides obtained by the way of equivalent or equivalent transformation Case, all falls within protection scope of the present invention.
