Abstract
The utility model provides a vacuum feeding system which comprises a filtering bin and a storage bin. A material inlet and a material inlet valve are arranged at the lower part of the filtering bin; a filter is arranged in the middle of the filtering bin; a vacuum pump is arranged at the top of the storage bin; a material outlet and a material outlet valve are arranged at the bottom of the storage bin; the vacuum feeding system is characterized in that a pressure pump is arranged at the top of the filtering bin; a first valve is arranged between the filtering bin and the storage bin; a vacuum meter and a liquid level indicator are arranged on the outer surface of the storage bin; and an air inlet and an air inlet valve are also arranged at the top of a liquid storage bin. The vacuum feeding system has the advantages and the benefits that quantitative feeding is realized, solid waste residue in material solution is effectively filtered, residual material solution in the filtering bin is used for timely cleaning the filter, not only the cost is saved, but also the phenomenon that the filtering speed during secondary feeding is affected because the filter is blocked is avoided, the vacuum feeding system is simple to operate, and is applicable to promotion and application in the project of ethylene polyol barren liquor purification.
Description
Technical field
The utility model relates to a kind of vacuum feed system, especially relates to a kind of vacuum feed system that the how pure lean solution purifying technique of ethene is used that is used for.
Background technology
In chemical field, for the recovery and the purification of waste water, waste residue, can protect environment can economize on resources again, therefore paid close attention to by increasing people.Wherein, The aqueous products that contains ethylene glycol, diethylene glycol and other alcohols that purification obtains to the how pure lean solution of ethene (promptly distilling raffinate remaining in the ethylene glycol production process); As the quality raw materials of producing the modulation cooling fluid, and alternative ethylene glycol produces engine coolant, can twice laid; Can turn waste into wealth again economizes on resources, and also can be enterprise and creates good economic benefit and social benefit.The vacuum feed system that uses in the existing how pure lean solution purifying technique of ethene, effectively the solid slag in the filter material solution for the subsequent production link is brought certain influence, needs further perfect.
Summary of the invention
The purpose of the utility model provides the vacuum feed system of the solid slag in a kind of effectively filter material solution, is particularly useful for the purification project of the how pure lean solution of ethene.
The technical scheme that the utility model adopts is:
A kind of vacuum feed system comprises filtering cabin and storage bin, and said filtering cabin bottom is provided with charging aperture and inlet valve; The filtering cabin middle part is provided with filter, and the filtering cabin top is provided with force (forcing) pump, and the storage bin top is provided with vavuum pump; The storage bin bottom is provided with discharging opening and bleeder valve; Be provided with first valve between filtering cabin and the storage bin, said storage bin outer surface is provided with vacuum meter and level indicator, and the containing liquid chamber top also is provided with air inlet and intake valve.
Preferably, said filtering cabin bottom also is provided with slag-drip opening and residual cake valve.
Advantage and the good effect that the utlity model has are: realize dosed; Solid slag in effective filter material solution; And utilize the material solution that remains in the filtering cabin that filter is in time cleaned; The rate of filtration when not only having practiced thrift cost but also having avoided influencing charging once more because of plugged filter, and simple to operate, be suitable in the purification project of the how pure lean solution of ethene, applying.

The specific embodiment
As shown in Figure 1 a kind of vacuum feed system; Comprise filtering cabin 1 and storage bin 2, said filtering cabin 1 bottom is provided with charging aperture 5 and inlet valve 4 and slag-drip opening 7 and residual cake valve 6, and filtering cabin 1 middle part is provided with filter 3; Filtering cabin 1 top is provided with force (forcing) pump 8; Storage bin 2 tops are provided with vavuum pump 10, and storage bin 2 bottoms are provided with discharging opening 16 and bleeder valve 15, are provided with first valve 9 between filtering cabin 1 and the storage bin 2; Said storage bin 2 outer surfaces are provided with vacuum meter 13 and level indicator 14, and containing liquid chamber 2 tops also are provided with air inlet 12 and intake valve 11.
The course of work of this vacuum feed system is:
When the liquid level of the how pure lean solution of ethene in the storage bin 2 reaches the material level upper limit 17 of level indicator 14, close vavuum pump 10, the inlet valve 4 and first valve closing 9, bleeder valve 15 keeps and cuts out, and residual cake valve 6 is opened with intake valve 11.In storage bin 2, the vacuum in the vacuum meter 13 indication storage bins 2, when the vacuum in the storage bin 2 was zero, bleeder valve 15 was opened, and the how pure lean solution of ethene gets into distillation still from discharging opening 16.In filtering cabin 1, open force (forcing) pump 8, the how pure lean solution of ethene that utilization will remain in the filtering cabin 1 is accomplished the cleaning to filter 3 from the process that slag-drip opening 7 extrudes, and closes force (forcing) pump 8 then.
When the liquid level of the how pure lean solution of ethene in the storage bin 2 arrived the material level lower limit 18 of level indicator 14, bleeder valve 15, intake valve 11 and residual cake valve 6 were closed, and first valve 9 is opened with inlet valve 4, and the open vacuum pump 10 then, from charging aperture 5 charging once more.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
