Abstract
The utility model relates to a drying device of a rail transit air source system. The drying device comprises a membrane dryer and a regulating valve, wherein the regulating valve is connected to an air outlet end of the membrane dryer; a heating tube is arranged inside an oil-gas separator; a blowback air outlet of the regulating valve is connected with an air inlet of the heating tube; an air outlet of the heating tube is connected with a backflow port of the membrane dryer. By adopting the system, blowback heating is carried out by leading a blowback gas to the oil-gas separator, so as to improve the temperature of the blowback gas. Thus, the water absorbing capacity of the blowback gas is improved. The heated blowback gas is led back to the dryer, and the moisture in drying medium is taken away, so that the drying property of the dryer is improved.
Description
Technical field
The utility model relates to a kind of drying device of track traffic air supply system.
Background technology
Rail vehicle braking provides the compressed air of dried and clean with air supply system for brakes, and drier is one of key equipment of air supply system, and the drying property quality of drier has a significant impact the energy consumption of air supply system, effect and exhaust quality.The blowback mode of drier designs the direct drying effect that affects drier, is also related to the use cost of air compressor.Prior art is directly membrane dryer to be carried out to blowback again through membrane dryer blowback air out, but this blowback air high humidity is greatly affected the drying effect of drier.
Utility model content
The purpose of this utility model is: the defect that overcomes above-mentioned prior art, a kind of drying device of track traffic air supply system is proposed, this system can effectively improve the drying effect of back-blowing, and then improves the drying effect of drier, has reduced the use cost of air compressor.
In order to achieve the above object, the drying device of a kind of track traffic air supply system the utility model proposes, comprise membrane dryer, be connected in the control valve of described membrane dryer outlet side, it is characterized in that: a heating tube is set in gs-oil separator, the back-blowing gas outlet of described control valve connects the air inlet of heating tube, and the gas outlet of heating tube connects the back blow port of membrane dryer.
Further, the heating tube of the drying device of this track traffic air supply system is helical form.
The utility model adopts technique scheme tool to have the following advantages:
Blowback mode of the present utility model is blowback air heat regenerating method, and blowback air is introduced to gs-oil separator, carries out blowback air heating, improves the water absorbing capacity of blowback air, has improved the utilization rate of blowback air.Facts have proved, better, the identical blowback air rate of backheat mode drying effect of this invention, this inventive method is improved the drying effect of drier.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the drying device structural representation of the utility model track traffic air supply system.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the drying device of the present embodiment track traffic air supply system, comprise membrane dryer 1, be connected in the control valve 2 of membrane dryer 1 outlet side, gs-oil separator 3 is interior arranges a heating tube 4, the back-blowing gas outlet of control valve 2 connects the air inlet of heating tube 4, and the gas outlet of heating tube 4 connects the back blow port of membrane dryer 1.
Wherein, membrane dryer, its drying medium is doughnut, and it has selection permeability, and the diffusion velocity that hydrone sees through film is thousands of times of other gas.Moist compressed air, the high selectivity of flowing through hollow fiber film tube, steam partial pressure effect under, water diffusion is outside film pipe, compressed air is dried gradually in mobile process.The compressed air that film pipe exit is dry, through blowback orifice plate, carries out blowback to film pipe outer wall, while flowing through film pipe outer wall, takes away moist hydrone, makes to exist all the time steam partial pressure poor inside and outside film, and the wet gas in assurance film pipe is constantly to external diffusion.
The utility model is carrying out, before blowback, having increased blowback air being heated to this flow process to film pipe outer wall.
The course of work of the present utility model is as follows:
Air enters membrane dryer from the air inlet of membrane dryer, and the dry air flowing out after membrane dryer is dry enters control valve; The heating tube that the back-blowing of control valve is introduced in gs-oil separator heats; And then send into the back blow port of membrane dryer, carry out hot blast blowback.
Lubricating oil temperature in Oil-gas Separation bucket is higher than the temperature of blowback air, and spiral helicine heating tube has increased the area that blowback air is heated, make the blowback air of introducing have time enough and Oil-gas Separation bucket to divide the lubricating oil in bucket to carry out exchange heat, reach the object of intensification, thereby improve the water absorbing capacity of purge gas;
Blowback air after heating is out introduced into the back blow port of back-blowing device afterwards by helix tube, and the outer wall of membrane dryer is carried out to blowback, takes away moist hydrone, thereby reaches the enhancing of drying effect.
This back-blowing device has improved the temperature of blowback air, has increased to a certain extent the water absorbing properties of blowback air.Improved the drying effect of drier, reduced the use cost of air compressor, made the overall performance of air supply system have further improvement.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
