Description

A kind of paper-making black liquor to obtain regenerated resource automated installation

The utility model relates to a kind of environmental protecting device, especially a kind ofly is used to handle the paper-making black liquor to obtain regenerated resource automated installation.

Traditional treating paper-making black liquor generally adopts alkali reclaiming method, this equipment complexity, and the one-time investment costliness, the day operation expense is too high, and effect is not ideal enough, and restraining factors are too many, the medium and small enterprise of incompatibility.

The purpose of this utility model provides a kind of paper-making black liquor to obtain regenerated resource automated installation, it has broken away from the requirement of traditional technology, by black liquid is reached the purpose of separating black liquid with addition of soup, stir through mixing again, reclaim by receiving defeeder, taking off after filtration becomes clear water and Na-lignosulfonic acid after doing.Equipment is simple, and investment cost is low, and recycling black liquid effect is very remarkable.

The purpose of this utility model is achieved in that by housing, supervisory control desk and dissolving are formed, described housing top is provided with medicine storing pot, medicine storing pot links to each other with mixing reactor with water inlet pipe by chemical feed pipe, mixing reactor is connected with the co-agulation analy device by pipeline, wherein be equipped with wave mode spin mixing tank at housing bottom, be equipped with standby stirring wing in co-agulation analy device upper end, the co-agulation analy device joins by pipeline and flotation defeeder, the upper end of flotation defeeder is equipped with receives defeeder and electric motor, the lower end of flotation defeeder is provided with reliever, reliever links to each other with external dissolving by the pressure air-dissolving pipe, receive the defeeder bottom and be equipped with discharge groove, it links to each other with water knockout by drainage conduit, and the flotation defeeder is connected with the filtration chamber by pipeline.Be provided with coarse filtration layer, finly filtration layer and water outlet in the described filtration chamber.Be provided with pervious course, adsorption layer and discharge port, discharge outlet in the described water knockout.Described receipts defeeder is provided with transmission shaft, be equipped with on the transmission shaft to receive and take off the material web plate, the transmission shaft two ends are equipped with recessed the wheel, and recessed the wheel is stuck on the capable rail that is fixed on the housing, also are equipped with the chain rail on the transmission shaft and are connected with the bearing that links to each other with electric motor and variable-speed motor by gear.Reliever is 2 at least.On the described flotation defeeder plastic, transparent shield cap can be housed.

The utility model has the advantages that: it is fast to handle black liquid speed, flow is big, cost is low, can make and account for the Na-lignosulfonic acid of pollution load more than 30% in the black liquor and almost all separate out, and be condensed into Φ 3-10mm colony, this apparatus structure compactness, handle the water yield big (investing more than 1.5 times of processing on an equal basis) for general technology, take up an area of few (being the sixth of common processes), cost low (be general administer pollution engineering 60%), duration short (be general technology 30%), (per tour one people easy to operate, for general technology 50%), the day-to-day operation expense is low.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a sectional view of the present utility model.

Fig. 3 is a vertical view of the present utility model.

Fig. 4 is a partial enlarged drawing of the present utility model.

In Fig. 1 to Fig. 4, symbol is represented successively: 1, housing 2, water inlet pipe 3, chemical feed pipe 4, medicine storing pot 5, medicine storing pot 6, wave mode spin mixing tank 7, chemical feed pipe 8, standby stirring wing 9, pipeline 10, pipeline 11, pressure air-dissolving pipe 12, reliever 13, receive defeeder 14, chain rail 15, electric motor 16, water outlet 17, finly filtration layer 18, coarse filtration layer 19, pipeline 20, water knockout 21, discharge port 22, discharge outlet 23, pervious course 24, adsorption layer 25, sump pump 26, check ladder 27, discharge groove 28, drainage conduit 29, variable-speed motor 30, bearing 31, transmission shaft 32, recessedly take turns 33, row rail 34, gear 35, power wheel 36, mixing reactor 37, co-agulation analy device 38, flotation defeeder 39, filtration chamber 40, receipts are taken off the material web plate.

Wherein black liquid enters mixing reactor 36 with the black liquor hybrid reaction by the analysis flocculation agent that sump pump 25 enters in 2 while of the water inlet pipe medicine storing pot 4 in proportion by chemical feed pipe 3, extract (Na-lignosulfonic acid) can be separated out fast, and preliminary cohesion forms little floc sedimentation.In co-agulation analy device 37 with medicine storing pot 5 in the further hybrid reaction of flotation peptizer the little floc sedimentation of extract (Na-lignosulfonic acid) can be condensed fast, form than large group.The black liquor of initial set enters flotation defeeder 38 by pipeline 10 by analysis, and extractable content Na-lignosulfonic acid forms the above bulk flocculation colony of Φ 0.5CM in the black liquor at this moment.Have the water of gas this moment by pressure air-dissolving pipe 11 force feed in reliever 12 by dissolving, the aerosol come-up that is produced by reliever 12 forms the condition of solid-liquid separation, because the gas release depressurization makes flocculation colony's floating upward quickly and further condensation form the solid substance layer that uninterruptedly gathers; At this moment, electric motor 15 is set positive and negative operation and the time-delay relay degree of receiving defeeder 13 on demand by variable-speed motor 29, extractable content is promptly scraped into discharge groove 27 from the water surface automatically, automatically flow into water knockouts 20 via drainage conduit 28, finish extractable content through adsorbents adsorb and natural hydrophobic process and reach the reprocessing condition; The clear liquid of extract water outlet enters filtration chamber 39 by pipeline 19, passes through coarse filtration layer 18 and finly filtration layer 17 again, is flowed out by water outlet 16.The standby stirring wing of installing in the co-agulation analy device 37 8 is implemented agitating function according to the difference of handling soiling solution or sewage situation by outer dress driven by motor, thereby makes chemical reaction complete, on the flotation defeeder 38 the plastic, transparent shield cap can be housed, and works to prevent rainwater.
