Description
Technical field
The invention belongs to compressed air, energy-conserving and environment-protective technical field, relate to a kind of absorption drier dew point accurate
Control system and method for adjustment.
Background technology
Dew point is user's the key technical indexes to quality requirements of calming the anger, and absorbed type drying machine technology is to realize dew point
The technical way required.Absorption drier generally uses clean gas dew point control methods to carry out automatically controlling,
Adjusting, when dried clean gas dew point temperature is higher than setting value, this adsorption barrel adsorption process terminates, and enters
Adsorbent is dried reproduced state；It is switched to another standby adsorption barrel adsorb, and so forth, switches.
Original system is that compressed air sends into absorption drier through piping, controls to send use after drying through dew point
Family.Dried clean gas dew point temperature performance for from low to high more low to high process.This mainly due to
Adsorbent is in adsorption process, and the characteristic that absorbability is gradually reduced determines.In terms of practical operation situation,
Drying machine is in adsorption process, and clean gas dew point temperature is for a long time less than the dew point temperature of user's needs.It is not difficult
Finding out, in adsorption process, the stage ultra-low dew point phenomenon of clean gas is a kind of unnecessary waste.
In order to solve the deficiency that above-mentioned prior art exists, a kind of scheme of existing offer.
Summary of the invention
It is an object of the invention to provide a kind of absorption drier dew point accuracy-control system and method for adjustment, right
User's gas carries out dew point and accurately controls, and in minimizing adsorption process, clean gas stage ultra-low dew point phenomenon is unnecessary
Waste, it is achieved energy-saving and cost-reducing purpose.
The purpose of the present invention can be achieved through the following technical solutions:
Absorption drier dew point accuracy-control system, including compressed air piping, cooled dehydrated unit, dust
Filter unit, absorption drier unit and the online dew point hygrometer of user, described compressed air piping is successively
It is connected with cooled dehydrated unit, dust filter unit unit；Described dust filter unit unit divides two-way to connect,
Wherein, a road is connected with absorption drier unit, another Lu Yupu gas electric control valve, general gas bypass phase
Connection；Above-mentioned two-way remerges after being connected, and is then connected with mother's user pipe, and this mother's user pipe is disposed with user and exists
Line dew point hygrometer.
Absorption drier dew point accuracy-control system method of adjustment, this method of adjustment comprises the steps,
Close general gas electric control valve, set user's pressure leak source required value；
Absorption drier unit starts absorption, and now drying machine outlet dew point dew point hygrometer online with user is identical；
PLC instructs general gas electric control valve to open greatly, adjusts the control online dew point hygrometer of user and wants to user's pressure leak source
More than evaluation；
PLC instructs general gas bypass electrodynamic valve gradually to turn down to closedown；
When drying machine outlet dew point reaches user's pressure leak source required value, drying machine adsorption barrel switches, and PLC instructs
General gas bypass electrodynamic valve is opened greatly, and so forth.
Beneficial effects of the present invention: compressed air piping is increased cooled dehydrated unit, dust filter unit by the present invention
Unit and the bypass of general gas, point two-way after cooled dehydrated unit, dust filter unit of calming the anger enters adsorption-type and does
Dry machine and the bypass of general gas, the clean gas after the absorption of drying machine send user after mixing with general gas in the bypass of general gas, uses
Family end pipeline is located at line dew point hygrometer, instructs general gas bypass electrodynamic valve to adjust general throughput, accomplishes general gas and clean gas
Rational proportion, it is achieved user's dew point accurately controls.
Accompanying drawing explanation
For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is present configuration schematic diagram；
In figure: 1-compressed air piping；2-cooled dehydrated unit；3-dust filter unit unit；4-adsorption-type is done
Dry machine unit；5-general gas electric control valve；The general gas of 6-bypasses；The online dew point hygrometer of 7-user.
Detailed description of the invention
1, absorption drier dew point accuracy-control system, as it is shown in figure 1, this system composition and function are as follows:
2, the connecting mode of absorption drier dew point accuracy-control system, sees Fig. 1；
After compressed air piping 1 is connected with cooled dehydrated unit 2, dust filter unit unit 3 successively, it is divided into two
Road, a road is connected with absorption drier unit 4, another Lu Yupu gas electric control valve 5, general gas bypass 6
Being connected, two-way is connected with mother's user pipe after remerging, and mother's user pipe is disposed with the online dew point hygrometer of user 7.
3, method of adjustment
It is provided with the online dew point hygrometer of user 7 by family end pipeline, instructs the general gas electric control valve 5 of general gas bypass 6
Adjust general throughput；
If user's pressure leak source requires as-20 DEG C, when absorption drier unit 4 starts to adsorb, drying machine
Outlet dew point about-70 DEG C；When general gas electric control valve 5 cuts out, the online dew point hygrometer of user 7 is also-70 DEG C,
PLC instruct general gas electric control valve 5 open greatly, general gas mixes with clean gas, control the online dew point hygrometer of user 7 to
More than-20 DEG C, along with (the online dew point of user) of drying machine outlet dew point promotes, PLC instructs the bypass of general gas
Electrodynamic valve gradually turns down to cut out；When drying machine outlet dew point reaches-20 DEG C, drying machine adsorption barrel switches,
About-70 DEG C of drying machine outlet dew point (the online dew point of user), PLC instructs general gas bypass electrodynamic valve to open greatly, as
This is reciprocal.
Compressed air piping is increased cooled dehydrated unit, dust filter unit unit and the bypass of general gas, pressure by the present invention
Gas point two-way after cooled dehydrated unit, dust filter unit enters absorption drier and the bypass of general gas, warp
Clean gas after drying machine absorption send user, user side pipeline to be located at line dew point after mixing with general gas in the bypass of general gas
