Abstract
A dry-cleaning machine solvent distillation box includes a box body and a heating tube. The heating tube is parallel fixed at the external wall of the box body. The heating tube is a closed dust parallel welded at the external wall with a cross section of a concave plate and the external wall; The two ends of the concave plate are connected with a tube side shell welded at the connection of the two ends. The tube side shell is welded and sealing with all semicircle arc plate i.e. the external wall of the heating tube, at the same time, the tube side shell is provided with a intake and outlet opening of the heating tube. The tube comprising the semicircle arc plate is fixed at the bottom side and the side wall of the heating tube. An inner hollow cavity of the semicircle arc plate of the utility model is comprising of a steam tube, with advantages of saving material and installment column, and low cost.
Description
Technical field
The utility model relates to the solvent recovery and the regeneration distilling apparatus of dry cleaner.
Background technology
Water and solvent mixture are discharged with regard to being boiled into steam, only stay body refuse.The water and the solvent vapo(u)r condensation in condenser again of discharging, and be to separate at oil water separator.Solvent vapor recovery device solvent vapor recovery device,
Tetrachloro-ethylene (comprising other dry cleaning agent) distillation is the method that the dry-cleaning dealer recycles tetrachloro-ethylene.In this operation with cross or unclean solvent (tetrachloro-ethylene that just contains excessive solvable and nonvolatile residue such as aliphatic acid, grease and oil) be heated to boiling point (250 or 121 ℃) or volatilize near boiling point.Those residual impurities because of boiling point than tetrachloro-ethylene height, and be left on the distillation case the bottom, become body refuse.The tetrachloro-ethylene vapor stream that does not contain body refuse is liquefied as the mixture of solvent and water through a condenser, through an oil water separator (liquid separator) moisture is removed again, and the tetrachloro-ethylene after the distillation is then got back to the river in Henan Province solvent tank and reused.The distillation case of dry cleaner divides three classes: electrothermal, steam heated formula and full water vapour heating type, extensively adopted by manufacturer.
The oven dry of solvent must be removed water wherein before solvent returns solvent tank.This carries out in a simple and highly effective oil water separator.When the mixture of water and solvent is flowed through oil water separator, above the water lighter than solvent floats over, and drained; , under the dividing plate of oil eliminator, discharge than water solvent heavily from the opposite side of oil water separator.Small portion of residual impurity in the solvent tends to moisture is retained in the solvent, but when solvent cooled off, centrifugation will be strengthened.Therefore, in oil water separator, adorn a cooling coil usually.
The running temperature of distillation case can not be higher than the boiling point (250 or 121 ℃) of tetrachloro-ethylene, to prevent the causing material of stink and solvent to seethe with excitement together.At this moment, water and solvent mixture are discharged with regard to being boiled into steam, only stay body refuse.The water and the solvent vapo(u)r condensation in condenser again of discharging, and be to separate at oil water separator.Solvent vapor recovery device solvent vapor recovery device can be collected in the factory building in the air, the tetrachloro-ethylene steam in the aerating system of recover, the machine of working.The air of these band solvent vapo(u)rs is by cilium gatherer of the fan warp let-off of a brute force, and cilium and other materials are filtered there, and remaining solvent-laden air is through the activated carbon beds in collecting, and solvent vapo(u)r just has been absorbed.Row is clean, not solvent-laden air to the outside.
CN2769298 is a kind of closed dry cleaner, and it includes laundry wheel, the air blast that gas circulation is used in the machine, the machine intercooler that solvent condenses is used, oven dry and the heater that solvent is vaporized, the circulating pump that solvent is circulated in machine or the solvent distillation is circulated, the distillation case, distillation case cooler, reclaim the liquid separator of solvent, the thermal source of distillation and oven dry usefulness, the pipeline of delivery solvent during work, the pipeline of solvent refluxing, conveyance conduit during cleaning solvent, condense into returning of solvent after the distillation and stay pipeline, the pipeline of cooling water, the circulating line of thermal source steam.
Yet existing distillation case generally adopts the tube heater structure, and material expends more, the cost height, and also shared volume is big.Structurally still leave some room for improvement.
Summary of the invention
The utility model purpose is: a kind of distillation case of simple structure is provided, saves material and installation volume, cost is lower.
The utility model purpose is achieved in that a kind of dry washer still box, comprise casing and water back composition, its feature water back is fixed on the outer wall of casing side by side, and water back is that the cross section is that notch plate constitutes closed duct with outer wall and is welded on the outer wall side by side; The two ends of notch plate and at tube side shell of its connection place arranged side by side welding, tube side shell and each semicircular arc plate are the outer wall welded seal of water back, are provided with the import and export of water back on the tube side shell simultaneously.
Characteristics of the present utility model are: the internal cavity of semicircular arc plate constitutes vapor line, saves material and installation volume, and cost is lower.

Fig. 2 is that the A-A of Fig. 1 is to sectional view
Distillation box body 1, water back 2, semicircular arc plate 3, outer wall 3-1, the import and export 5,6 of tube side shell 4, water back.
The specific embodiment
Dry washer still box comprise distillation box body 1, water back 2,, semicircular arc plate 3, outer wall 3-1, tube side shell 4.Casing is generally made by stainless steel, water back is fixed on the outer wall of casing, notch plate has multiple choices: as half rectangular slab (lack a wall), half elliptic, especially be welded on side by side with the semicircular arc plate and constitute water back on the outer wall, the two ends of semicircular arc plate and at tube side shell of its connection place arranged side by side welding, tube side shell (having on the shell and the corresponding spill of semicircular arc plate outer wall) is the outer wall welded seal of water back with each semicircular arc plate, and the import and export 5,6 that are provided with water back on the tube side shell simultaneously are used to pass through heating steam.
The pipeline that the semicircular arc plate constitutes can be fixed on base and the sidewall.
Claims (3)
1, a kind of solvent of dry cleaner distillation case comprises casing and water back composition, it is characterized in that water back is fixed on the outer wall of casing side by side, and water back is that notch plate constitutes closed duct with outer wall, is welded on side by side on the outer wall; The two ends of notch plate and at tube side shell of its connection place arranged side by side welding are provided with the import and export of water back simultaneously on the tube side shell.
