Working principle of the utility model is: the utility model is to joined supersonic speed separation in compressed air dehydration
Technology utilizes supersonic speed isolation technics as shown in Figure 1, replacing the cooling driers 16 in original system with supersonic speed isolation technics
Separative efficiency is high, small in size, low energy consumption, simplifies the features such as technique, and it is general to solve cooling driers 16 in existing compressed air dewatering system
The problems such as inconvenient all over the existing climate repair and maintenance that influences that big, water removal rate is low, energy consumption is high, the device is complicated.Air is via sky
Air and cohesion after air compressor 1, Laval nozzle 2 and fixed-wing guide vane 11, into gas-liquid separator 3, after separation
Water respectively enter gas-collecting pipe 5 and water tank 4 is collected.
The structure of Laval nozzle 2 and fixed-wing guide vane 11 is simple, untreated air, by air compressor
After 1, it is provided with certain initial velocity, is entered in Laval nozzle 2 along pipeline, due to 2 caliber change of Laval nozzle, root
According to the principle of " when fluid moves in pipe, the small place's flow velocity in section is big, and section general goal flow velocity is small ", air velocity is improved rapidly, warp
Most narrow place's speed is crossed more than velocity of sound, air enters rapid spatial expansion in pipeline, under adiabatci condition, gas pair after accelerating
Outer acting, inside can be reduced, and temperature reduces rapidly, and the hydrogenesis in air, gas-liquid mixture is the case where possessing fair speed
Down by fixed-wing guide vane 11, under the influence of blade 14, centrifugal force is generated, drop therein is fixed wing guide vane
11 intercept, and are thrown on tube wall in the effect of centrifugal force, under the drive of high-speed flow, air and liquid enter gas-liquid separator
3, then collect respectively.
As shown in Figure 1, increasing No.1 lateral 10, be conducive to the growth and nucleation of drop, convenient for subsequent moisture
Cohesion and collection, it is artificial at this time to keep the skin wet into the air for entering Laval nozzle 2, it is equivalent into gas and nucleation is added
Agent can accelerate the moisture condensation in air, compared to traditional system being dehydrated by cooling driers, go water rate by original
30% is increased to 80%.
As shown in figure 4, the increased fixed-wing guide vane 11 after Laval nozzle 2, in fixed-wing guide vane 11
Axis 12 is designed to circular arc parabolic shape, and tail portion is coniform.Blade 14 is designed to that circular arc parabolic shape, such design can make
The air for just touching fixed-wing guide vane 11 generates centrifugal force, the attachment of moisture agglomerated in air on blade 14 or
It is attached on tube wall under the influence of centrifugal force convenient for collecting, gas air-flow velocity after fixed-wing guide vane 11 is more flat
, vortex is not generated, can realize gas-liquid separation effect very well.
As shown in Fig. 2, No. two laterals 15 are increased, the cooling driers in No. two laterals 15 and original dewatering system
16 connections, are divided into two parts by the air of air compressor 1, and by No.1 electric switching valve 22 and No. three electric switching valves 29
It controls respectively, this design can make full use of the cooling driers 16 in original dewatering system, accomplish to make the best use of everything, in legacy system
In transformation, new system can be configured by simple operations, applicability is stronger.
As shown in figure 3, further increasing 17, No. three laterals of anti-backflow switch valve on the basis of existing system
18, air accumulator 19 and air accumulator safety valve 20, the moisture in air is after Laval nozzle 2 and fixed-wing guide vane 11
Gas-liquid separation is had been realized in, most of dry air enters air accumulator 19 via No. three laterals 18, then is mentioned by air accumulator 19
For the compressed air needed for producing, remainder gas-liquid mixture enters gas-liquid separator 3 through pipeline, and is provided in inlet
The progress place of anti-backflow switch valve 17, this design is that air accumulator 19 can continue as using when carrying out system equipment maintenance
Gas equipment provides compressed air, and after closing anti-backflow switch valve 17, can be effectively prevented water in gas-liquid separator 3 due to
Pressure in device, which acts on, to flow backwards, the other equipment in damage system into main pipeline.
As shown in Figure 2 and Figure 3, No. four laterals 32 are increased under the prior system, and are pacified on No. four laterals 32
Spare regulating valve 33 is filled, the stability for capableing of better safeguards system operation is added in backup line.In actual production process
In, flow control valve 27 frequently uses, and controls No.1 lateral 10 and supply water for Laval nozzle 2, the possibility of failure damage
Property is bigger, so increase No. four laterals 32 in the side of No.1 lateral 10, can flow control valve 27 not
Safeguards system continues stable operation when can work normally.Manual switch is also added in the front and rear sides of flow control valve 27 simultaneously
