Technical field
The utility model belongs to technical field of chemical, relates to a kind of waste disposal plant, especially relates to a kind of contains sodium sulfate waste disposal plant.
Background technology
Sodium sulfate is a kind of mineral compound, and Disodium sulfate decahydrate has another name called saltcake, and white, odorless, the crystallization that has bitter taste or powder, have water absorbability.Profile is colourless, transparent, large crystallization or the little crystallization of graininess.Be mainly used in water glass processed, glass, enamel, paper pulp, refrigeration mixture, washing composition, siccative, dye-dilution agent, analytical chemistry reagent, pharmaceuticals etc.
Because sodium sulfate is of many uses, therefore in the enterprise that uses sodium sulfate or production sodium sulfate, can there is the sewage of a large amount of contains sodium sulfate, these sewage, as directly entered in environment, can cause the waste of resource on the one hand, also can cause on the other hand the pollution of environment.Produce at present sodium sulfate and conventionally use the crystallizing process under low temperature, this method energy consumption is higher, and is not suitable for the processing of large batch of sewage.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of contains sodium sulfate waste disposal plant is provided; Solved that the existing energy consumption of prior art is high, technical problem that can not mass disposal contains sodium sulfate sewage.
For achieving the above object, the utility model has adopted following technical proposal: a kind of contains sodium sulfate waste disposal plant, comprise medicament storage tank, described medicament storage tank connects a pump, and a described pump connects mixing tank, and described mixing tank connects inclined plate sedimentation pond, described inclined plate sedimentation pond connects whizzer, described whizzer connects vaporizer by the first valve, and described vaporizer connects No. two pumps, and No. two described pumps connect spray drying device.
In above-mentioned contains sodium sulfate waste disposal plant, described whizzer is also by the second valve junctional membrane thickener, and described membrane concentrator connects vaporizer.
In above-mentioned contains sodium sulfate waste disposal plant, described whizzer is tripod pendulum type batch centrifugal, horizontal screw centrifuge or disc centrifuge.
In above-mentioned contains sodium sulfate waste disposal plant, described vaporizer is multiple-effect falling film formula vaporizer or scraper-type vaporizer.
In above-mentioned contains sodium sulfate waste disposal plant, described membrane concentrator is ceramic membrane thickener, nanofiltration membrane thickener or reverse osmosis membrane thickener.
Compared with prior art, the utility model has the advantage of: simple in structure, easy to operate, energy consumption is low, energy mass disposal contains sodium sulfate sewage, the sodium sulfate product obtaining can be used as industrial use after further processing, and has reached the effect of waste reclaimation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment 1 that provides of the utility model;
Fig. 2 is the structural representation of the embodiment 2 that provides of the utility model.
In figure, medicament storage tank 1, pump 21, No. two pumps 22, mixing tank 3, inclined plate sedimentation pond 4, whizzer 5, the first valve 61, the second valve 62, vaporizer 7, membrane concentrator 8, spray drying device 9.
Embodiment
As shown in Figure 1, a kind of sodium sulfate waste disposal plant, comprise medicament storage tank 1, described medicament storage tank 1 connects pump 21 No. one, and a described pump 21 connects mixing tank 3, and described mixing tank 3 connects inclined plate sedimentation pond 4, described inclined plate sedimentation pond 4 connects whizzer 5, described whizzer 5 connects vaporizer 7 by the first valve 61, and described vaporizer 7 connects pump 22 No. two, and No. two described pumps 22 connect spray drying device 9.
Described medicament storage tank 1 is interior can place the flocculant solution preparing in advance, these flocculation agents can be that organic floculant can be also inorganic flocculating agent, object is that a pump 21 of flocculation agent is got in mixing tank 3, after mixing, the mud of the inside and heavy metal etc. is formed to throw out by mixing tank 3 with sewage.
In inclined plate sedimentation pond 4, throw out starts a large amount of sedimentations, liquid after sedimentation arrives whizzer 5 after deriving from inclined plate sedimentation pond 4 and carries out further solid-liquid separation, described whizzer 5 is tripod pendulum type batch centrifugal, horizontal screw centrifuge or disc centrifuge, and the particle content in the liquid after solid-liquid separation is few.
To through above-mentioned liquid after treatment, with vaporizer 7, carry out moisture evaporation, the metabisulfite solution after further being concentrated.Described vaporizer 7 is multiple-effect falling film formula vaporizer or scraper-type vaporizer.
Metabisulfite solution after concentrated is with being driven in spray drying device 9 and spraying and be dried with No. two pumps 22, obtain the sodium sulfate solid of powdery, sodium sulphate content in these sodium sulfate solids can reach 70-90wt%, after further refining, can obtain sodium sulfate more than 95wt%.
Embodiment 2
As shown in Figure 2, structure and the working process of the present embodiment and embodiment 1 are basic identical, and difference is, described whizzer 5 is also by the second valve 62 junctional membrane thickeners 8, and described membrane concentrator 8 connects vaporizer 7.Described membrane concentrator 8 is ceramic membrane thickener, nanofiltration membrane thickener or reverse osmosis membrane thickener, selects dissimilar membrane concentrator, can select according to the difference of the impurity in sewage and molecular weight.
When carrying out the concentration of the fluid sulphuric acid sodium solid-liquid separation from whizzer 5 when lower, can first with membrane concentrator 8, tentatively concentrate, because membrane separation apparatus 8 does not need steam heating conventionally, current consumption is also less, therefore can reduce a large amount of power consumptions.Metabisulfite solution after concentrated is further concentrated with vaporizer 7 again.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
