Description
Technical field
The present invention relates to a kind of air flue simplification device, relate to specifically a kind of Heatless regenerative adsorption dryer regeneration air flue simplification device.
Background technology
When flowing through rapidly reducing, orifice plate or narrow slit, gas causes that owing to overcoming local resistance the remarkable phenomenon declining of pressure is called throttling.Gas has little time while there is throttling in runner to exchange more heat with the external world, generally all thinks approx to carry out under adiabatic condition.
In engineering, for meeting actual needs, often utilize Choking phenomenon to reduce pressure, adjusting or the measuring flow of fluid.In pipe-line system, for different application purposes, structure and the working mechanism of throttling arrangement are all very different.For example:
While utilizing the poor flow that carrys out measuring channel fluid of restricting orifice pressure at both sides, require orifice plate front and back must leave the straight length of corresponding length, and make the pressure of orifice plate downstream one segment distance inner fluid will substantially return to the value before throttling, very strict to restricting orifice each several part dimensional requirement for this.
In refrigeration system, be connected on that throttle mechanism between condenser and evaporimeter must closely be followed evaporating pressure or the compressor air suction degree of superheat changes to supply with the refrigerant flow adapting with cooling system amount.When regulating liquid supply rate, capillary has shown adjusting initiative owing to having auto-compensation, heating power expansion valve relies on temperature-sensitive bag to carry out passive receive conditioning signal and changes fluid latus rectum, although therefore these two kinds of throttle mechanism principles, structure and even profiles are completely different, all there is the ability of self-control liquid supply rate.
In the typical case application of above-mentioned phenomenon, throttle mechanism is not only the indispensable part that flies in fluid circuit, and the normal work that throttling caliber size and fluid flow direction all can fluid system brings tremendous influence.
Adsorption dehumifier is reseted the throttle orifice of putting to be had and the diverse object of above-mentioned throttle mechanism, thereby has some suitable features of self working.Absorption type dryer regeneration gas is being undertaken the task of the steam that desorbing being taken away to drying tower, as long as it is just enough that its pressure must and overcome adsorbent bed, because while receiving at a certain temperature gauge water steam, pressure approximately approaches atmospheric pressure, and the tolerance of consumption is fewer.The effect of throttle orifice is exactly passage is provided and its pressure is down to and is approached atmospheric pressure by operating pressure for dry regeneration gas.
Throttle orifice role in absorption type dryer is compared in the throttle mechanism of aforementioned typical, has following feature:
Except guarantee regeneration pressure approach with atmospheric pressure, throttle orifice does not need to possess flow regulating function conventionally.
2. the throttle orifice of absorption type dryer should possess the ability of bidirection air intake.
3. the reduction of throttling function.
4. regeneration gas passage.
