Abstract
The utility model discloses a dimethyl sulfoxide waste salt recovery device, which relates to a sulfoxide waste salt treating device and solves the problems that the raw materials are wasted due to the traditional sulfoxide waste salt treatment, the economic benefit is reduced, and the environment is polluted. The dimethyl sulfoxide waste salt recovery device comprises a continuous evaporator, a concentration tank, a crystallization kettle, a centrifugal machine, a mother liquor tank, a salt dissolving tank and a press filter which are sequentially connected through pipelines, wherein the press filter is connected with the continuous evaporator again through a pipeline so as to form circulation, the pipelines which are respectively connected with the continuous evaporator, the concentration tank, the crystallization kettle and the centrifugal machine are provided with valves, a stirring machine is also arranged above the crystallization kettle, and a clamp sleeve of the crystallization kettle is connected with the pipelines which are provided with the valves. The dimethyl sulfoxide waste salt recovery device disclosed by the utility model has the advantages that the structure is simple, the operation is convenient, the investment is less, the cost is saved, the production cost of an enterprise is beneficial to lower, and the economic benefit is increased.
Description
Technical field
The utility model relates to sulfoxide abraum salt treatment unit, is specifically related to a kind of dimethyl sulfoxide (DMSO) abraum salt retrieving arrangement.
Background technology
Abraum salt source in the sulfoxide production process mainly is, nitrogen peroxide in the thick sulfoxide and sodium hydroxide become neutral sulfoxide after nitrate that neutralization reaction generates and sulfoxide mix, evaporate under negative pressure through continuous evaporator and concentration tank, most of sulfoxide and sulfone are steamed the dehydration tower dehydration and are become dense product sulfoxide, remaining is exactly abraum salt, its main component is SODIUMNITRATE, some sulfone and sulfoxide.
There are the two kinds of methods of burning and directly drain in present existing sulfoxide manufacturer to the processing of abraum salt, has not only wasted raw material but do like this, has reduced economic benefit, contaminate environment, and do not meet the process for cleanly preparing requirement.
Because for solving the existing unscientific problem of sulfoxide abraum salt treatment process, be necessary to research and develop a kind of new sulfoxide retrieving arrangement, thereby improve existing recovery method.
Summary of the invention
The utility model is to have not science of sulfoxide abraum salt treatment unit now in order to solve, and that causes wastes raw material, and reduces economic benefit, the problem of contaminate environment, and a kind of dimethyl sulfoxide (DMSO) abraum salt retrieving arrangement is provided.
The utility model is realized by following scheme;
A kind of dimethyl sulfoxide (DMSO) abraum salt retrieving arrangement, comprise the continuous evaporator, concentration tank, crystallization kettle, whizzer, mother liquor tank, change salt bath, the pressure filter that connect successively by pipeline, pressure filter is connected with continuous evaporator by pipeline again, form circulation, wherein connect respectively on the pipeline of continuous evaporator, concentration tank, crystallization kettle and whizzer and be provided with valve, the top of crystallization kettle also is equipped with stirrer, and the chuck of crystallization kettle is connected with the pipeline of valve.
Further, described concentration tank is 2-4, is connected in parallel by pipeline and continuous evaporator and crystallization kettle respectively.
The steam that during production and application continuous evaporator is produced passes in the concentration tank by establishing valvular pipeline, when the abraum salt temperature reaches 110 ℃ of left and right sides, open Valved discharge in crystallization kettle, wherein be watered in the 5:1 ratio is past, constantly stir by stirrer, when stirring, in the crystallization kettle chuck, pass into circulating water by establishing valvular pipeline, adjust stirrer (90r/min) rotating speed and cooling rate (temperature is down to about 30 ℃ after 90 minutes), the slurry that cooling ends in the crystallization kettle is put into whizzer and is separated, use technique water washing filter cake during separation, filter cake after the drying is that crystalline salt (SODIUMNITRATE about 95%) pack deposits storehouse in, isolated squeezing into of mother liquor salt bath is heated to 80 ℃ and mixes the solid abraum salt stirring and dissolving of originally hoarding by Filter Press in the 5:1 ratio, and clear liquid returns the reuse of continuous evaporator double evaporation-cooling.
The utility model is simple in structure, easy to operate, invest lessly, reduce expenses, being conducive to enterprise reduces production costs, increase economic efficiency, need not in packing of product process that especially high-temperature molten salt is entered the salt pond and treat that naturally cooling packs again, not only reduced labour intensity but also eliminated various unsafe factors, the SODIUMNITRATE purity that obtains is high, primary crystallization purity reaches more than 95%, and the SODIUMNITRATE yield is high, can reach about 98%.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1-concentration tank, 2-crystallization kettle, 3-whizzer, 4-mother liquor tank, 5-ization salt bath, 6-pressure filter, 7-stirrer, 8-continuous evaporator.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of dimethyl sulfoxide (DMSO) abraum salt retrieving arrangement, comprise the continuous evaporator 8, concentration tank 1, crystallization kettle 2, whizzer 3, mother liquor tank 4, change salt bath 5, the pressure filter 6 that connect successively by pipeline, pressure filter 6 is connected with continuous evaporator 8 by pipeline again, form circulation, wherein connect respectively on the pipeline of continuous evaporator 8, concentration tank 1, crystallization kettle 2 and whizzer 3 and be provided with valve, the top of crystallization kettle 2 also is equipped with stirrer 7, and the chuck of crystallization kettle 2 is connected with the pipeline of valve.
