Abstract
The present invention relates to a kind of drying means of Track traffic air source system, connect control valve at the air outlet of membrane dryer, the air-out of membrane dryer is divided into two strands by control valve, and first burst of air-out sends into reservoir as dry gas, and second burst of air-out is as back-blowing; In the gs-oil separator under car, install helical metal pipe, introduced by back-blowing after helical metal pipe heats and carry out blowback to the doughnut of membrane dryer again, the air quantity of second burst of air-out of control valve accounts for the 10-15% of total air-out volume.Blowback air is introduced gs-oil separator by the present invention, carries out blowback air heating, improves the water absorbing capacity of blowback air, improves the utilization rate of blowback air.Facts have proved, the backheat mode drying effect of this invention is better, and under identical drying effect, required back-blowing tolerance is less, can obtain more dry air, reaches the effect of saving source of the gas; Back-blowing and lubricating oil heat exchange simultaneously, serves the effect to lubricating oil cooling.
Description
Technical field
The present invention relates to the drying means of Track traffic air source system.
Background technology
Rail vehicle braking air supply system provides the compressed air of dried and clean for brakes, and drier is one of key equipment of air supply system, and the good and bad energy consumption to air supply system of drying property of drier, effect and exhaust quality have a significant impact.The blowback patten's design of drier directly affects the drying effect of drier, is also related to the use cost of air compressor.The air quantity ratio of classical inverse blowing is higher, be generally 20-25%, cause the waste of source of the gas, and blowback efficiency is lower.
Summary of the invention
Technical problem to be solved by this invention is, overcome the above-mentioned deficiency of prior art, provide a kind of drying means of Track traffic air source system, blowback air is introduced gs-oil separator and is carried out blowback air heating by it, improve the water absorbing capacity of blowback air, improve the utilization rate of blowback air.
In order to solve above technical problem, the drying means of Track traffic air source system provided by the invention, it is characterized in that: the drier of air supply system adopts membrane dryer, the air inlet of membrane dryer to be given a dinner for a visitor from afar source, the air outlet of membrane dryer connects a control valve, the air-out of membrane dryer is divided into two strands by control valve, and first burst of air-out sends into reservoir as dry gas, and second burst of air-out is as back-blowing; The helical metal pipe of a dip lubrication oil is installed in the gs-oil separator under car, described back-blowing is introduced after helical metal pipe heats and again blowback is carried out to the doughnut of membrane dryer, take away film pipe outside moisture and discharge air by infiltration mouth, the air quantity of second burst of air-out of described control valve accounts for the 10-15% of total air-out volume (back-blowing ratio).
The present invention further improves and is: described helical metal pipe is helical form copper pipe.
The inventive method is applied to track air supply system, and use the drying medium of membrane dryer to be doughnut, it has selective penetrated property, and hydrone is thousands of times of other gas through the diffusion velocity of film.Moist compressed air, flows through high selectivity hollow fiber film tube, steam partial pressure effect under, water diffusion is to outside film pipe, and compressed air obtains drying gradually in the process flowed.
The compressed air of film pipe exit drying, becomes more dry through the decompression of blowback orifice plate, flows through film pipe outer wall and takes away moist hydrone, make to there is steam partial pressure difference all the time inside and outside film, and the wet gas in guarantee film pipe is constantly to external diffusion.Malaria is continuously continual by process whole in blowback to atmospheric environment, and the generation of dry air is also continuously, by the size of adjustment backflowing gas amount, can obtain different compressed air drying degree, to realize most economical drying.
The blowback mode of patent of the present invention is blowback air heat regenerating method, and blowback air is introduced gs-oil separator, carries out blowback air heating, improves the water absorbing capacity of blowback air, improves the utilization rate of blowback air.Facts have proved, the backheat mode drying effect of this invention is better, identical blowback air rate, and this inventive method makes the drying effect of drier be improved; Obtaining under identical drying effect, back-blowing tolerance required during use the present invention program is less, can obtain more dry air, reaches the effect of saving source of the gas; Back-blowing and lubricating oil heat exchange simultaneously, serving the effect to lubricating oil cooling, is achieve many things at one stroke.
Accompanying drawing explanation
Fig. 1 is drying device structural representation involved by the present invention.
Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, be clearly and completely described below to the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.
As shown in Figure 1, for embodiment of the present invention drying device used, specifically comprise membrane dryer 1, be connected to the control valve 2 of membrane dryer 1 outlet side, a helical form copper pipe 4 is set in gs-oil separator 3, the back-blowing gas outlet of control valve 2 connects the air inlet of helical form copper pipe 4, and the gas outlet of helical form copper pipe 4 connects the back blow port of membrane dryer 1.
The drying means of the present embodiment Track traffic air source system, the drier of air supply system adopts membrane dryer 1, the air inlet of membrane dryer 1 to be given a dinner for a visitor from afar source, the air outlet of membrane dryer 1 connects a control valve 2, the air-out of membrane dryer 1 is divided into two strands by control valve 2, first burst of air-out sends into reservoir as dry gas, and second burst of air-out is as back-blowing; The helical form copper pipe 4 of a dip lubrication oil is installed in the gs-oil separator under car, back-blowing is introduced after helical form copper pipe 4 heats and again blowback is carried out to the doughnut of membrane dryer 1, take away film pipe outside moisture and discharge air by infiltration mouth, the air quantity of second burst of air-out of control valve 2 accounts for the 10-15% of total air-out volume.
In addition to the implementation, the present invention 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 application claims.
