Description
Technical field
The invention discloses a kind of vacuum system automatic draining device and mating automatic control systems.
Background technique
During vacuumizing, such as in rectification under vacuum operating process, often due to pipeline is longer, heat insulation measure
Be not good at, the operation factors such as operating parameter is unstable cause the material medium in vacuum pipe to congeal into drop, ultimately form hydrops into
Enter vacuum equipment, adverse effect is caused to equipment, even results in equipment damage, and then not can guarantee system vacuum, influence just
Often production.
Vacuum equipment is usually placed on ground, is arranged in certain height if being evacuated equipment (such as overhead condensate reflux tank)
Degree, to meet the net positive suction head requirement of reflux pump.Since vacuum equipment inlet duct is too long, pipe insulation provision for thermal insulation is not good at,
The material medium carried secretly in vacuum pipe is easy condensation and forms drop, ultimately forms hydrops.Therefore, it is transported to guarantee that equipment is stablized
Often liquid separation tank is arranged in mechanical compression equipment entrance in row.
For traditional liquid separation tank due to the presence of vacuum condition, equipment, which is arranged height and put, will meet breaking vacuum between net point
The requirement of pressure at receiving device is spent and meets, therefore equipment position is higher.Meanwhile to guarantee that each pressure system separates,
To guarantee that certain liquid level as fluid-tight, avoids " altering pressure ", causes vacuum system unstable in liquid separation tank.
Summary of the invention
Automatic vacuum liquid-drainaged device of the invention increases demarcation plate realization one and sets inside traditional liquid separation tank base
For two interior pressure, automatic drain, while matched with self-control control valve system are realized by potential difference inside equipment, realized entirely certainly
Dynamicization operation.Meanwhile purged by inert gas pressure, ground can be placed a device in, so on present apparatus face with vacuum equipment
Arrangement recently, it is too long to avoid pipeline between liquid separation tank and vacuum pump, forms time condensation.
Present apparatus design scheme is as follows: liquid separation tank integrally suggests being designed as vertical storage tank, is arranged inside liquid separation tank and tilts
Partition board, partition top is liquid separation area, and lower part is hydrops area, is connected between two regions by pipeline, realize that high point is vented,
Low spot drain, is arranged automatic stop valve in connecting pipe, needs to realize connection according to operation and separates, system is avoided " to alter
Pressure ".
A kind of vacuum system automatic draining device is equipped with one and horizontal plane including closed hollow vessel in the middle part of tank body
Tank interior is separated into upper and lower two by the partition board tilted, partition edge and inner tank wall face airtight connection, partition
A mutually disconnected chamber, partition top is liquid separation area, lower part is hydrops area, and the right end of partition upper surface is located above left end,
Liquid separation area bottom is set to form right high left low inclined surface；
Tank body left end in the middle part of liquid separation area is equipped with air inlet, in being equipped with air flap in tank body at air inlet, by air inlet
The gas that mouth flows into tank body enters liquid separation area in air flap lower end；Top of the tank in liquid separation area is equipped with gas outlet；
It is equipped with drain through-hole in partition board left end, or in partition board left end equipped with the groove as collecting tank, liquid collecting
The bottom of slot is equipped with drain through-hole；Catheter is equipped in drain through-hole lower end；
In hydrops area top tank body right end at partition be equipped with gas balance mouth, gas balance mouth by gas-guide tube with
Liquid separation area is connected；Leakage fluid dram is equipped in the tank body lower end in hydrops area.
The present apparatus can use a variety of intake methods, and design scheme is as follows:
Intake method one: spiral deflector is arranged in device air inlet, and vacuum gas is set from the side rotary-cut of liquid separation area to entrance
It is standby, rotation tangential admission is realized by spiral deflector, carries out gas-liquid separation using the density contrast of gas and material, advantage is gas-liquid
Separative efficiency is high, the disadvantage is that device structure is complicated, requirement on machining accuracy is high, and equipment difficulty of processing and processing cost increase；
Intake method two: flow apron is arranged in device air inlet, realizes that the inertial separation of gas-liquid, advantage are equipment difficult processings
Spend small, disadvantage is to realize efficiently separating for gas and material, according to droplet size, to there is the liquid separation area of enough height.
Collecting tank is arranged in inclined clapboard low spot inside equipment, and the two sides of spikes/low- points collecting tank are realized by connecting pipe to be filled
Set being connected to for liquid separation area and hydrops area.Partition is uniformly arranged fan-shaped drain groove, to facilitate baffle surface liquid to partition low spot
Collecting tank confluence.
Since liquid separation area and hydrops area carry out even energy by connecting pipe, two area's static pressure are identical, the liquid in liquid separation area
Cognition is slipped in inclined clapboard low spot collecting tank along inclined clapboard diversion trench, by flowing to hydrops area communicating pipe.
Such structure design, has liquid separation area space compared with high separating efficiency, to reduce equipment volume.When hydrops area
When interior liquid level reach a certain height, automatic interlock carries out vacuum breaker drain.
Drain automatically control: when hydrops area liquid level is higher (LSHH001), starting interlocking, close communicating valve XV001 and
XV002 separates in liquid separation area and hydrops from two valve position feedbacks open nitrogen valve XV003 without mistaking, and hydrops area pressure reaches pre-
When definite value, interlocking close XV003 opens tapping valve XV004 and carries out drain, when the emptying rate of liquid in hydrops area, closes
XV004.At this point, the pressure rate in hydrops area is maintained to be greater than downstream pressure.After liquid empties, XV001 and XV002 are reopened.
Hydrops area volume is small as far as possible, on the one hand reduces liquid residence time, on the other hand reduces hydrops area to vacuum
System causes excessive pressure to fluctuate, this depends on vacuum system ability etc. and liquid measure factor is divided to determine.
Ripple hydraulic barrier is arranged in present apparatus liquid separation tank deck, and two of liquid separation area gas before entering vacuum pump may be implemented
Secondary gas-liquid separation.
Ripple hydraulic barrier low spot goes out drainage hole by machinery, as shown in Fig. 2, hydraulic barrier lower edge machinery punching
Protrusion retains, and corrugated baffle inner product advantageous in this way flows down.
Ripple hydraulic barrier is arranged in present apparatus liquid separation tank deck, using ripple hydraulic barrier, can be kept off in gas by baffling
When plate, flow-disturbing is generated, gas-liquid separation is more conducive to.
