Abstract

The utility model discloses a highly efficient solid-liquid separator in the technical field of the solid-liquid separation. The highly efficient solid-liquid separator comprises a separating tube presenting a funnel shape, a sludge outlet is arranged at the bottom of the separating tube, a top cover is arranged at the top of the separating tube, a waste acid inlet and an air exhaust opening are arranged on a top cover, an overflow opening is arranged between the upper opening and the top cover of the separating tube, a central cylinder extended into the separating tube is vertically arranged under the waste acid inlet, a hatch is arranged at the bottom of the central cylinder, and a plurality of shunting holes are arranged on the side wall of the central cylinder. During operation, the waste acid liquid after being preprocessed can enter into the central cylinder from the waste acid inlet, the part clear liquid can directly flow out of the shunting holes, the rest liquid including deposits can enter into the separating tube from the bottom part of the central cylinder to perform the further deposition, the relevant uncontaminated clear liquid can flow out of the overflow opening, and the deposits at the bottom of the separating tube can be discharged from the sludge outlet. The highly efficient solid-liquid separator has the advantages that the efficiency of the solid-liquid separation is high, the structure is simple, the manufacturing is convenient, and the highly efficient solid-liquid separator is not easy to block, and can be used for the purifying section treatment in the pyrite acid producing process.

Description

Efficient solid-liquid separator

Technical field

The utility model relates to a kind of chemical industry equipment, particularly a kind of equipment for separating liquid from solid.

Background technology

In the pyrite-based sulfuric acid production production process, the gas that boiling roaster goes out, after waste heat boiler, cyclone dust collectors and cottrell cooling dedusting: temperature is 320 ℃～350 ℃, dust quantity 180～200mg/NM ³, and a spot of SO ₃Gas.When gas enters the purification section equipment for washing again, meet the water contact and produce diluted acid, recycle repeatedly, the concentration and the dust content of diluted acid are higher, need reduce dust content in the circulation cooling diluted acid with solid-liquid separator, improve the operating efficiency of cleaning equipment, solve the problem of sour mud blocking pipe and equipment.Existing solid-liquid separator, mainly comprise and be funnel shaped cylinder, the cylinder bottom is provided with sludge outlet, the cylinder top is provided with top cover, top cover is provided with dirty sour import and exhaust outlet, be provided with overfall between the suitable for reading and top cover of cylinder, be provided with some inclined tube fillers in the cylinder, in order to increase the contact area of liquid and solid, during its work, contaminating enterprises are formulated the requirement of " three wastes " discharge standard according to country, the dirt that purification section is discharged is sour, add an amount of limewash and flocculant, by the mechanical agitation neutralization reaction, measure pH value and be 5～7% when neutral, squeeze in the cylinder of solid-liquid separator from the sour import of dirt with pump again, after staticly settling, being solid-state material can emit from sludge outlet, delivers to the slag field with mortar pump, and the clear liquid that top overflows discharges after meeting national standard, but non-compliant repeated treatments is until up to standard; A small amount of gas is discharged from exhaust outlet.Its weak point is, the liquid that dirty sour import comes freely falls in the cylinder, can impact upper clear supernate, and interior with just the entering cylinder easily unsegregated liquid of clear liquid after the separation is mixed mutually, causes separating effect relatively poor.

The utility model content

The purpose of this utility model provides a kind of efficient solid-liquid separator, can reduce newly to enter the interior liquid of cylinder to the disturbance of separating liquid, makes solid-liquid separation effect better.

The purpose of this utility model is achieved in that efficient solid-liquid separator, comprise and be funnel shaped cylinder, the cylinder bottom is provided with sludge outlet, the cylinder top is provided with top cover, top cover is provided with dirty sour import and exhaust outlet, is provided with overfall between the suitable for reading and top cover of cylinder, and the sour import of described dirt below uprightly is provided with the central tube that stretches in the cylinder, the central tube bottom opening offers some tap holes on the sidewall of central tube.

During the utility model work, through pretreated pH value is that 5～7% dirty acid solution bodies enter in the central tube from the sour import of dirt, the part supernatant liquid directly flows out from tap hole, contain sedimentary liquid enters close bottom in the cylinder from the center tube bottom position, the precipitation that helps solid matter so more, Jie Jing supernatant liquid can flow out from overfall relatively, the sediment of cylinder bottom can unload downwards from sludge outlet to be put, compared with prior art, in the utility model, the disturbance that dirty acid solution body enters in the cylinder is few, can reduce newly to enter the interior liquid of cylinder to the disturbance of separating liquid, improves the efficient of Separation of Solid and Liquid.The utility model is simple in structure, easily manufactured, is difficult for stopping up, and the clean-up stage that can be used in the pyrite-based sulfuric acid production technology is handled, and improves the operating efficiency of cleaning equipment, avoids sour mud blocking pipe and equipment.

As further improvement of the utility model, be positioned in the described central tube dirty sour import under be provided with a choked flow cone.When dirty acid enters in the central tube, at first contact the choked flow cone, the choked flow cone stops dirty acid, and its flow velocity is slowed down, and avoids directly impacting the sediment of cylinder inner bottom part downwards.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the partial enlarged drawing of A among Fig. 1.

Wherein, 1 overfall, 2 central tubes, 3 cylinders, 4 sludge outlets, 5 dirty sour imports, 6 choked flow cones, 7 exhaust outlets, 8 top covers, 9 tap holes.

The specific embodiment

As Fig. 1, be efficient solid-liquid separator, comprise being funnel shaped cylinder 3, cylinder 3 bottoms are provided with sludge outlet 4, and cylinder 3 tops are provided with top cover 8, and top cover 8 is provided with dirty sour import 5 and exhaust outlet 7, for convenient maintenance, can offer manhole on top cover 8; Be provided with overfall 1 between the suitable for reading and top cover 8 of cylinder 3, dirty sour import 5 belows uprightly are provided with the central tube 2 that stretches in the cylinder 3, and central tube 2 bottom openings offer some tap holes 9 on the sidewall of central tube 2; Be positioned in the central tube 2 dirty sour import 5 under be provided with a choked flow cone 6.The anti-corrosion material that device fabrication can be used, as fiberglass or steel lining PE all can, the cost of material is low.

During work, through pretreated pH value is that sour import 5 enters in the central tube 2 5～7% dirty acid solution bodies from dirt, at first contact choked flow cone 6, choked flow cone 6 stops dirty acid, its flow velocity is slowed down, avoid directly impacting the sediment of cylinder 3 inner bottom parts downwards, the part supernatant liquid directly flows out from tap hole 9 then, slowed down flow velocity, help the solids sedimentation, contain sedimentary all the other liquid and therefrom enter cylinder 3 interior positions in heart tube 2 bottoms near the bottom, the precipitation that helps solid matter so more, Jie Jing supernatant liquid can flow out from overfall 1 relatively, and the sediment of cylinder 3 bottoms can unload downwards from sludge outlet 4 to be put, gas port is discharged from exhaust outlet 7, and above-mentioned emission all can further be handled and make its qualified discharge.
