Feed gas purified through an adsorption device enters a product buffer tank, a small part of product gas enters an analytical instrument, and a proper operational mode is selected by a controller according to the detection data of the analytical instrument, so that the adsorption device is always in the optimal operational state. The control mode comprises a brute force mode, a standard mode, an energy-saving mode and a super energy-saving mode. The contradiction between the supply and demand and energy consumption of the product gas is balanced by varying the operational modes, so that the optimum point is achieved.
Description
Technical field:
Pressure change adsorption type nitrogen processed, PSA oxygen generator, pressure change adsorption type hydrogen manufacturing, the isallobaric absorption type device of pressure change adsorption type drying machine.
Technical background:
Pressure swing adsorption method (Pressure Swing Adsorption, be called for short PSA) be a kind of new gas separation, developed rapidly abroad from the beginning of the seventies at the end of the sixties, its principle is to utilize various molecular sieves that the difference of gas with various molecule " absorption " performance is separated admixture of gas.Pressure swing adsorption method uses two towers in parallel usually, hocket pressurization absorption and decompress(ion) regeneration, thus obtain continuous product air-flow.At present its general way is: use fixedly adsorption time to control fixing valve change action and realize the punching press of adsorption tower, absorption, all pressure, step-down regenerative process.Its motion flow is: when a tower when doing the action of punching press, absorption, another tower is being done the process of step-down regeneration.After the adsorption tower of doing punching press, absorption reached fixing adsorption time, with the process of all pressing at the adsorption tower of doing step-down regeneration, then two tower actions were switched, and the alternate cycles action produces gas product incessantly.The major defect of this type of pressure-variable adsorption separation equipment is:
1. equipment is under startup and normal operation, and equipment can not change operational mode according to actual conditions, makes its gas product can not in time satisfy use.
2. equipment often is that parameter with device design disagrees in actual motion, and equipment can not adjust automatically according to actual conditions.
3. when the user reduces the use gas product, when the gas product quality of equipment output is higher than designing requirement, having consumed unnecessary raw material, also is a kind of waste concerning the user.
4. strengthen when using gas product even slightly exceeding the device design parameter as the user, equipment can not Self-adjustment, does not satisfy and uses the gas requirement.
5. equipment is to open time motion efficiency low, and gas product touches the mark slowly.
Summary of the invention:
The present invention has solved above-mentioned practical problem well by rational system control method.
Intelligent pressure-swing absorption apparatus of the present invention comprises adsorbent equipment 1, controller 2, analytical instrument 3 and gas product surge tank 4.Wherein adsorbent equipment is connected with the product surge tank by pipeline, and adsorbent equipment is connected with controller by signal transmssion line, and the product surge tank is connected with analytical instrument by pipeline, and analytical instrument is connected with controller by signal transmssion line.Unstripped gas enters the product surge tank after by the adsorbent equipment purifying, and the sub-fraction gas product enters analytical instrument, and controller makes adsorbent equipment be in all the time best running status according to the suitable operational mode of the detection data selection of analytical instrument.
In order to address the above problem, the present invention realizes by following step order:
Device start is opened the sample analysis valve, and gas product is delivered to analytical instrument 3 by sampling line and detected.
After analytical instrument 3 detected the result, analytical instrument 3 compared data and becomes the comparing data results conversion signal of telecommunication to pass to controller 2 by data wire with the data of setting.
Compare with prior art, benefit of the present invention is: fully reasonable use equipment, and it is worked under the running status of the best all the time, give full play of the optimum efficiency of equipment.Realize the optimum balance of production capacity and energy consumption.
Description of drawings:
Figure of description Fig. 1 is the process chart of intelligent pressure-swing absorption apparatus, and package unit comprises: 1. adsorbent equipment, 2. controller, 3. analytical instrument, 4. gas product surge tank.
The specific embodiment:
Below in conjunction with Fig. 1 (process chart) specific embodiment the present invention is done into detailed description:
The present invention realizes by following step order:
Start, equipment enters powerful pattern.Equipment uses fast and switches the adsorption tower working time, and shorten all pressures time of two adsorption towers in powerful operational mode process.The unstripped gas that consume this moment also can suitably increase, but realizes the purpose of quick aerogenesis.Improve output and shorten the available machine time.In the situation that the equipment that also can be adapted to slightly works overloadingly.
Equipment is in powerful mode operation, unstripped gas is delivered to analytical instrument 3 by signal piping and is detected, the data of data and setting compare after detecting, and the result passed to controller 2 by data wire by phased manner, if index is lower than and sets value then that controller 2 control appliances remain running in the powerful pattern, if being better than setting value, index then escalates into mode standard.
Equipment is in the stan dard running model process, and the switching adsorption tower working time that Application standard is general, two adsorption towers that reach standard universal are all pressed the time.This moment, equipment operated in the running environment of standard, conformed to the design parameter of equipment.
Equipment is in service in mode standard, unstripped gas is delivered to analytical instrument 3 by signal piping and is detected, the data of data and setting compare after detecting, and the result passed to controller 2 by data wire by phased manner, if index is lower than and sets value then that the controller control appliance is downgraded in the powerful pattern, if being better than setting value, index then escalates into energy saver mode.
Equipment uses and switches at a slow speed the adsorption tower working time, and postpone all pressures time of two adsorption towers in the energy conservation model process.And in two tower transfer processes, be provided with stop, reduce the leakage of unstripped gas.The unstripped gas that consume this moment also can suitably reduce, and the output of gas product also suitably can reduce.Realized reaching energy-conservation target in the situation that gas consumption reduces to reduce the consumption of unstripped gas.
Equipment is in service at energy saver mode, unstripped gas is delivered to analytical instrument 3 by signal piping and is detected, the data of data and setting compare after detecting, and the result passed to controller 2 by data wire by phased manner, if index is lower than and sets value then that the controller control appliance is downgraded in the mode standard, if being better than setting value, index then escalates into super energy saver mode.
Equipment is in super energy conservation model process, and usage comparison switches at a slow speed the adsorption tower working time, and increases all pressures time of two adsorption towers.And in the processes such as the conversion of two towers, balance, be provided with stop, more a step ground reduces the leakage of unstripped gas.The unstripped gas that consume this moment can reduce significantly, and the output of gas product also can reduce.Realized in the situation that the consumption of the smaller minimizing of gas consumption unstripped gas reaches energy-conservation target.
Equipment is in service at super energy saver mode, unstripped gas is delivered to analytical instrument 3 by signal piping and is detected, the data of data and setting compare after detecting, and the result passed to controller 2 by data wire by phased manner, if index is lower than and sets value then that controller 2 control appliances are downgraded in the energy saver mode, if being better than setting value, index then maintains in the super energy saver mode.
