Description
Technical field
The utility model relates to a kind of freeze drier de-watering apparatus.
Technical background
Compressed air is as a kind of power, because superiority that it is outstanding and gradually ripe purification techniques, make it in the application of every field more and more widely and more and more important, than other power form (for example electronic, surge etc.), compressed air has its original advantage.Progress and perfect day by day along with compressed air drying and purification techniques.The compressed air drying equipment supporting with it is also flourish.Than other many compressed air drier technology, freezing type drier has remarkable advantages, as: the air-flow treating capacity is big, and power consumption is few, and pressure drop is little, reliable noiselessness or the like.Because these advantages and strong point, freezing type drier is being served as the effect of main force in the compressed air drying field.
The freezing type drier main flow mainly is made up of three systems: 1, compressed air cooling system; 2, gas-water separation system or water scavenging system; 3, drainage system.Whether gas-water separation is thoroughly most important to the influence of the dew point of giving vent to anger of freezing type drier.Compressed air stably is cooled to optimum temperature, air is thorough as far as possible with separating of water, isolated water to be discharged reliably, this is three necessary conditions that the freezing type drier of a function admirable should possess.
At present, the gas and water separator of frozen compressed air dryer has three kinds of mode: a. to filter; B. whirlwind; C. collision.Under the identical situation of working condition, their separating mechanism and effects separately are compared as follows:
A. filter: this method mainly is that the solid, liquid body particle in the gas is tackled, other two kinds of separation relatively, and this method gas-water separation is the most thorough, and the dew points at normal pressure of exhaust can reach one 20 ℃, is generally-15 ℃.Shortcoming is that pressure drop is big, and filter core will regularly replace.
B. whirlwind: mechanism is to utilize solid, liquid body particle different with the mass density of gas, and inertia is also different, and when airflow direction changed, the big solid, liquid body particle of inertia was owing to its direction of malleable not and separated from the gas.Its structure is the simplest, and non-maintaining substantially, resistance is little.Shortcoming is the dew point height, and dew points at normal pressure generally is not less than-10 ℃.
C. collision: mechanism is to utilize collision to make liquid particles stick to the surface of solids, and simple in structure, non-maintaining substantially, resistance is little.Shortcoming is that dew point is higher, and dew points at normal pressure is minimum to reach-14 ℃, is generally-11 ℃.
In the gas and water separator of present frozen compressed air dryer, all only adopted a kind of in the above method.
Summary of the invention
For overcoming the above-mentioned shortcoming of prior art, the utility model provides a kind of simple in structure, dew points at normal pressure is low, resistance is little, non-maintaining substantially gas and water separator or de-watering apparatus.
A kind of freeze drier de-watering apparatus, comprise container, described chamber wall is provided with the gas outlet that the air inlet that Open Side Down and opening make progress, be provided with near first homogenizing plate of air inlet and second homogenizing plate of close gas outlet at described internal tank, the rear away from described air inlet of described first homogenizing plate is provided with a filter screen that can filter steam, be provided with the gas-water separation chamber between described filter screen and described second homogenizing plate, bottom, described gas-water separation chamber is provided with discharge outlet.
Further, described homogenizing plate is the foraminate flat board that gathers, and the pore diameter range of described aperture is 0.5～8mm, and the spacing range between the described adjacent aperture is 1～20mm, and the aperture number range on the described homogenizing plate is 40～1000.
Further, the screen net structure of described filter screen for adopting stainless steel or other resistant material twine to be woven into, the diameter range of described twine is 0.1～2mm, the number of plies scope of described screen net structure is 1～50 layer, the thickness range of described screen net structure is 1～100mm, and the described mesh order scope of counting is a per inch 5～50.
Technical conceive of the present utility model is: compressed air enters from air inlet, and speed is higher, and behind first homogenizing plate, the speed step-down also evenly is full of cross section of fluid channel; In this stage, a part of water is separated by first homogenizing plate; Gas moves on through filter screen, with the twine collision, is filtered by twine in net, and most of water is separated in this stage; Under the effect of second homogenizing plate, air continues evenly to advance with low velocity after breaking away from filter screen, and remaining most of aqueous water relies on self gravitation to be separated in the gas-water separation chamber in the air; Air is discharged from the gas outlet, and water is discharged from the discharge outlet of bottommost.
The utlity model has advantage simple in structure, that dew points at normal pressure is low, resistance is little, non-maintaining substantially.
