Abstract
The invention relates to a purification recycling device. The purification recycling device comprises a compressor, a water separation device, a drier, an oil-gas separation device and a refrigeration steel bottle, wherein the refrigeration steel bottle is put in a cooling tank, and is communicated with the cooling tank by a pipeline. An external plate type electric heater and a temperature controller are mounted on the water separation device; the drier uses activated aluminum oxide, a molecular sieve and allochroic silica gel for drying and filtering remainder moisture and acidic materials in gas; an outlet of the oil-gas separation device is divided into two pipelines: one is a Freon gas passage, and the other one is an oil way; one end of the oil way is connected with an oil container; the two pipelines are connected in a U-shaped manner; and finally, air is separated in the refrigeration steel bottle. The purification recycling device is simple in structure, and can separate water, oil and air from Freon to conveniently recycle the Freon in maintenance of refrigeration equipment so as to prevent the Freon waste and the environmental pollution.
Description
Technical field
The present invention relates to a kind of purification recovery device.
Background technology
In prior art, freon is generally acknowledged it is desirable refrigerant by people always, and therefore it is used in the every field of whole world all trades and professions widely.In use, the freon in some discarded refrigeration plants can be reclaimed, and also can discharge a large amount of freon to environment in air when unit maintenance.In currently available technology, vacuum pressure formula mainly taked by general refrigeration working medium reclaimer, utilizes compressor having internally mounted generation negative pressure to be aspirated by cold-producing medium and pour into steel cylinder to store.The type equipment shortcoming is to reclaim gas, liquid Mix refrigerant cycle (freon and refrigeration Dormant oils), cannot be separated the water in refrigeration working medium, oil and air.These impurity can cause condensing pressure to rise, unit refrigerating capacity declines, and the coefficient of performance reduces, overheat of compressor, and then causing the faults such as scuffing of cylinder bore, tile kilning, air valve carbon distribution, water in air part will cause parts corrosion, cold-producing medium and lubricating oil generation hydrolysis and go bad.
Summary of the invention
The object of the invention is for a large amount of harm of the fluorine water-oil mixture containing freon of discharge in productive life environment, there is provided a kind of and effectively can reclaim freon from the mixed liquor of freon, water and oil, avoid the purification recovery device of contaminated environment and the fund of saving.
By a kind of purification recovery device that this object designs, this device is provided with compressor, is connected with water separation device after compressor, drier is connected with after water separation device, be connected with gas and oil separating plant after drier, be connected with refrigeration steel cylinder after gas and oil separating plant, refrigeration steel cylinder is placed in cooling bath.
Further, water separation device bottom is provided with external plate electric heater, and upper end is provided with the temperature controller controlling electric heater.During use, opened by plate electric heater, temperature controls more than freon gasification temperature, and below water vapor temperature, such freon is heat vaporized, separates from water.
Further, drier uses activated alumina, molecular sieve and discolour silica gel to remaining aqueous vapor in gas and acidic materials carry out dry filter.
Further, gas and oil separating plant exit is divided into two pipelines, article one, be Freon gas path, one is oil circuit, and oil circuit one end is connected with oil container, article two, path connects in U-shaped mode, object is when retracting device runs, gas can not oil bring into refrigeration steel cylinder in, make oil amass U-shaped curved in, until curvedly to shut U-shaped, gas enters refrigeration steel cylinder from Freon gas path.
Further, the Freon gas deoiled through water past enters refrigeration steel cylinder, main oxygenous and nitrogen in air, condensing temperature is respectively-183 degree and-196 degree, therefore, steel cylinder temperature of freezing is arranged on below freon condensing temperature, more than oxygen-nitrogen condensing temperature, both can ensure that oxygen-nitrogen was discharged refrigeration steel cylinder, and liquid freon is stayed in refrigeration steel cylinder.

Detailed description of the invention
Below in conjunction with accompanying drawing, brief description is made to the specific embodiment of the present invention.
See accompanying drawing freon evolution retracting device, comprise compressor 1, be connected with water after compressor 1 to be separated and to fill 4 and put, drier 5 is connected with after water separation device 4, gas and oil separating plant 6 is connected with after drier 5, be connected with refrigeration steel cylinder 10 after gas and oil separating plant 6, refrigeration steel cylinder 10 is placed in cooling bath 11, for reclaiming pure freon.Water separation device 4 bottom is provided with external plate electric heater 3, and upper end is provided with the temperature controller 2 controlling electric heater.Gas and oil separating plant 6 exit is divided into two pipelines, and one is 7, one, Freon gas path is oil circuit 8, and oil circuit 8 one end is connected with oil container 9, and two paths connect in U-shaped mode.
During use, compressor 1 will be mixed with the freon press-in water separation device 4 of water, oil and air, and water separation device 4 bottom is provided with external plate electric heater 3, and upper end is provided with the temperature controller 2 controlling electric heater.Opened by external plate electric heater 3, temperature controls more than freon gasification temperature, and below water vapor temperature, such freon is heat vaporized.The gas separated from water enters into drier 5, drier 5 built with activated alumina, molecular sieve and discolour silica gel to remaining aqueous vapor in gas and acidic materials carry out dry filter.The dry gas of discharging enters gas and oil separating plant 6, gas and oil separating plant 6 exit is divided into two pipelines, article one, be 7, one, Freon gas path be oil circuit 8, oil circuit 8 one end is connected with oil container 9, article two, path connects in U-shaped mode, when retracting device runs, gas can not oil bring into refrigeration steel cylinder in, make oil amass U-shaped curved in, until curvedly to shut U-shaped, gas enters refrigeration steel cylinder 10 from Freon gas path.The Freon gas deoiled through water past enters refrigeration steel cylinder 10, main oxygenous and nitrogen in air, condensing temperature is respectively-183 degree and-196 degree, therefore, refrigeration steel cylinder 10 temperature is arranged on below freon condensing temperature, more than oxygen-nitrogen condensing temperature, both can ensure that oxygen-nitrogen was discharged refrigeration steel cylinder 10, and pure liquid freon is stayed in refrigeration steel cylinder 10.
The present invention has simple to operate, and freon reclaims advantage easily, avoids the waste of freon and the pollution to environment, is a kind of ideal freon recovery device.
