The vacuum slagging system has the advantages of environmental friendliness, convenience in transfer and transportation of residues and simple operation, and is suitable for popularization and application in ethylene polyol barren solution purification process.
Description
Technical field
The utility model provides a kind of vacuum dreg removing system, especially relates to a kind of vacuum dreg removing 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, Purification to the how pure lean solution of ethene (promptly distilling raffinate remaining in the ethylene glycol production process); Can reclaim ethylene glycol, diethylene glycol and other alcohol solutions in the useless alcoholic solution of this type again, be used for as the raw material of producing the modulation cooling fluid, not only environmental protection but also energy savings.The dreg removing system of using in the existing how pure lean solution purifying technique of ethene often needs and atmosphere in tapping process, makes that the pernicious gas in the waste residue overflows, and causes environmental pollution.In addition, dreg removing system is fixedly connected with distillation still and has brought inconvenience also for the transfer and the transportation of waste residue.
Summary of the invention
The purpose of the utility model provides a kind of not only environmental protection but also is convenient to the vacuum dreg removing system of the transfer and the transportation of waste residue, 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 dreg removing system, comprise the residue groove, take out slag ladle with take out the vavuum pump that slag ladle is connected, said residue groove and distillation still bottom is connected and is provided with first residual cake valve in this junction; Take out between slag ladle and the vavuum pump and be provided with vacuum valve; Take out the slag ladle bottom and be provided with slag notch and the 3rd residual cake valve, said residue groove top is provided with air inlet and intake valve, and residue groove outer surface is provided with liquid level upper limit indicating gage and liquid level lower limit indicating gage; The residue groove with take out slag ladle and be connected through dismountable tube connector; Be provided with second residual cake valve between residue groove and the tube connector, take out to be provided with between slag ladle and the tube connector and take out the slag valve, in the residue groove sealing fluid is housed.
Preferably, said residue groove is the taper of the vertex of a cone in the bottom.
Advantage and the good effect that the utlity model has are: owing to adopt the fluid-tight deslagging, pernicious gas in the waste residue is sealed in the system, avoids contaminated environment.Use dismountable tube connector, make that taking out slag ladle can separate, and conveniently is transported to the downstream product user with residue from system.In addition, adopt taper residue groove, make deslagging more thoroughly fast.The utility model is simple to operate, is suitable in the purifying technique of the how pure lean solution of ethene, applying.

The specific embodiment
A kind of vacuum dreg removing system as shown in Figure 1; Comprise residue groove 2, take out slag ladle 3 with take out the vavuum pump 5 that slag ladle 3 is connected, said residue groove 2 is connected with distillation still 1 bottom and is provided with first residual cake valve 6 in this junction, takes out between slag ladle 3 and the vavuum pump 5 and is provided with vacuum valve 11; Take out slag ladle 3 bottoms and be provided with slag notch 13 and the 3rd residual cake valve 12; Said residue groove 2 tops are provided with air inlet 7 and intake valve 8, and residue groove 2 outer surfaces are provided with liquid level upper limit indicating gage 14 and liquid level lower limit indicating gage 15, residue groove 2 with take out slag ladle 3 and be connected through dismountable tube connector 4; Be provided with second residual cake valve 9 between residue groove 2 and the tube connector 4; Take out to be provided with between slag ladle 3 and the tube connector 4 and take out slag valve 10, said residue groove 2 is the taper of the vertex of a cone in the bottom, in the residue groove 2 sealing fluid 16 is housed.
The course of work of this vacuum dreg removing system is:
Under intake valve 8 unlatchings, second residual cake valve, 9 closing state, open first residual cake valve 6, waste residue 17 gets into residue groove 2 from distillation still 1.Prescribe a time limit when liquid level upper limit indicating gage 14 prompting liquid levels reach on the liquid level, first residual cake valve 6 cuts out with intake valve 8.With residue groove 2 with take out slag ladle 3 and be connected through tube connector 4.Under the 3rd residual cake valve 12 closing state, with second residual cake valve 9, take out slag valve 10 and vacuum valve 11 is opened, open vacuum pump 5, waste residue 17 are inhaled into from residue groove 2 and take out slag ladle 3.Prescribe a time limit when liquid level lower limit indicating gage 15 prompting liquid levels reach under the liquid level, close second residual cake valve 9 and take out slag valve 10, open the intake valve 8 and first residual cake valve 6, repeat above operation continuation deslagging.After deslagging finishes, pull down tube connector 4, will take out slag ladle 3 and separate, deliver to the downstream product user with residue groove 2.
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.
