Light oil oil vapour separates and the fluid retracting device
Technical field
The utility model relates to a kind of device of organic matter vapor-liquid separation, and specifically a kind of light oil oil vapour separates and the fluid retracting device.
Background technology
The Environmental Protection Level of present domestic coal tar processing is lower, and the organic flue gas of part uncontrollable discharge is handled, and directly is discharged in the atmosphere, has caused the pollution of environment.By improving, the device that has utilizes blower fan to introduce the washing oil absorption tower flue gas is focused on the back discharging, but there is following defective in this technology: no vapor-liquid separation and liquid withdrawal system between smoke absorption pipe and the part oil heat exchanger, big gauging vapour enters the absorption tower and pollutes, also cause the loss of light oil products simultaneously, reduced the utilization rate of original product.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of reduction to pollute, and the light oil oil vapour that improves the light oil rate of recovery separates and the fluid retracting device.
Technical scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Light oil oil vapour separates and the fluid retracting device, except comprising the light oil cooler, diffuse valve, light oil groove and the smoke absorption device, also comprise the light oil dashpot that the light oil dashpot links to each other with the light oil cooler by diffusing valve; The upper end of light oil dashpot links to each other with the smoke absorption device, and the lower end links to each other with the light oil groove.
Wherein, the upper end of described light oil dashpot links to each other with the smoke absorption device by the smoke absorption pipe.
Wherein, described light oil dashpot is a closed container, and the bottom is a funnel-form.
Wherein, the connecting pipe of described light oil dashpot and light oil groove is provided with a control valve.
Beneficial effect: light oil oil vapour of the present utility model separates and fluid retracting device simple structure, easy for installation, the light oil oil stripping that comes out for bulk storage in the oil cooler has on the lenient side supplied cushion space to be convenient to fluid to separate, funnel type bottom by dashpot has been reclaimed fluid easily, both guaranteed that exhaust gas discharging reduces pollution, had improved the utilization rate of light oil again.

The specific embodiment
Further illustrate the utility model below in conjunction with accompanying drawing 1.
Light oil described in the utility model oil vapour separates and the fluid retracting device, except comprising light oil cooler 1, diffuse valve 2, light oil groove 3 and the smoke absorption device 4, also comprise light oil dashpot 5 that light oil dashpot 5 links to each other with light oil cooler 1 by diffusing valve 2; The upper end of light oil dashpot 5 links to each other with smoke absorption device 4, and the lower end links to each other with light oil groove 3.
Wherein, the upper end of described light oil dashpot 5 links to each other with smoke absorption device 4 by smoke absorption pipe 6.
Wherein, described light oil dashpot 5 is closed containers, and the bottom is a funnel-form.
Wherein, described light oil dashpot 5 is provided with a control valve 7 with the connecting pipe of light oil groove 3.
In the coal tar process, light oil enters oil water separator 8 by light oil cooler 5.Because the volatility of temperature and light oil, wherein part light oil oil vapour enters light oil dashpot 1 through pipeline, and this process is by diffusing valve 2 controls, and when light oil oil vapour reached certain pressure, being let pass entered pipeline.Light oil oil vapour carries out vapor-liquid separation in light oil dashpot 1, wherein light oil waste gas enters smoke absorption device 4 through smoke absorption pipe 6 and absorbs, and liquid light oil then flows into light oil groove 3.Because light oil dashpot 1 bottom is a funnel-form, is convenient to the collection and the recovery of liquid light oil.Light oil dashpot 1 is provided with a control valve 7 with the connecting pipe of light oil groove 3, is used to control the collection of liquid light oil.
The utility model provides a kind of light oil oil vapour to separate and the fluid retracting device; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
