Description
The present invention relates to a kind of control device of boiler plant, exactly, relate to a kind of boiler optimizating controller of realizing with microcomputer and other electromechanical integration series components and parts, belong to the control or the adjusting device technical field of on-electric variable.
The steam that becomes HTHP with the heat that boiler is sent in water pump feedwater and draws fuel discharges in burner hearth is sent Industrial Boiler extensive use in many industries such as metallurgy, machinery, chemical industry, generating, oil, weaving that boiler supplying uses and is had for a long time, the technology of boiler being carried out automation is also a lot of, but for taking all factors into consideration of aspects such as energy-saving safe, conventional existing automatic technology often can not reach more satisfactory degree, especially a kind of boiler of specific use, traditional conventional automatic technology are difficult to realize variable working condition control especially.For example, be used for thermal recovery boiler at the oilfield exploitation viscous crude, what its was exported is the moist steam of unsaturated state, the temperature of steam, pressure, mass dryness fraction three's relation is all relevant with the heat content of water vapour, it involves the state parameter relation of water vapour, its functional relation is very complicated, and being reflected in the production is that its condition of work is quite complicated, and the operating mode of high-temperature wet steam vapour is difficult to grasp.And present conventional automation can only do to decide the operating mode setting, can't realize that variable working condition control is to satisfy production and energy-conservation needs.
The purpose of this invention is to provide a kind of boiler optimizating controller that adopts electromechanical integration standard series equipment to constitute, thereby cancel the automation hardware wired logic circuitry of various control boiler operatiopns, improve functional reliability and carry out optimization control.
Hardware configuration of the present invention is as shown in Figure 1: it is (to use box indicating by the sensing element group, denominator is I in the frame), the executive component group (is used box indicating, denominator is O in the frame), interface interface case 8, communication converter 9 and microcomputer 10 are formed, wherein sensing element and executive component all are installed in boiler 1 and auxiliary equipment thereof (feed pump 2 respectively, blower fan 3, fuel control valve 4, liquid level gauge 5, steam outlet valve 6, exhanst gas outlet valve 7) on the relevant position, and it is connected with I/O adaptation module separately on the industrial control unit (ICU) that inserts 8 li in interface interface case (or claiming interface interface) by cable.The sensing element group includes boiler liquid level collecting unit WH, WL, smoke discharging temperature collecting cell TA, steam exit temperature collecting unit TS, steam pressure collecting unit PS, steam flow collecting unit QS, feedwater flow collecting unit QW, air flow rate collecting unit CA etc.The executive component group includes the unit CW of control speed of feedwater, the unit CA of control blower fan air output, the unit CV of the unit CF of control fuel control valve and control steam outlet valve.Interface interface case is equipped with an analog quantity interface interface and a digital quantity interface interface for 8 li, and the interface case is by two pairs of two-core cables and communication converter 9(AC7 plate) link to each other, take this to connect with the microcomputer 10 of control centre.Communication converter 9 converts it and the RS-232C Control on Communication formula of microcomputer to the RS422 communication standard and is communicated with interface interface case.
The present invention adopts electromechanical integration standard series equipment to constitute, data processing software based on information system is controlled in real time, thereby obtain following improvement effect: at first be the automation hard logic loop of having cancelled various control boilers, improved the reliability and the adaptability to changes of work greatly.Owing to adopting information technology, software control to replace conventional hard wired logic control, greatly widened the flexible and adaptive capacity of control, no matter how complicated parameter can both be controlled.The present invention is by carrying out real-time optimal treatment to data, the action of each executive component is drawn close to the optimum condition condition of setting as much as possible, make the wind supply quantity of blower fan, the feedwater of water pump and the supply of fuel reach optimum Match, the control of realization optimization, thereby realize efficient, energy-conservation comprehensive production index, can make boiler be in preferably the operation down of variable working condition state, this also is that boiler control equipment both domestic and external is up to now all failed the technical barrier of fine solution.
The industrial process control of operation principle of the present invention and common computer is identical: promptly the technological parameter of gathering various boiler for producing by sensing unit is delivered to adaptation module in the boiler interface interface case nearby by cable, by interface interface case these parameters are converted to and to calculate the signal that function receives and import into to it, each parameter by computer real-time acquisition and optimization process whole cooker furnace apparatus, and compare according to the optimum condition of setting, handle, the action parameter of each executing agency or element just is under control, make feed pump, the output of blower fan and fuel make up and steam is in optimum matching relation, and energy-efficient production steam satisfies industrial needs.
Microcomputer of the present invention can use various universal commercial microcomputers, has set up following mathematical relationship in the internal memory of microcomputer:
CF=f(PS, TS, TA) (saturated vapor)
Or: CF=f(PS, TS, TA, QS, QW) (unsaturation steam)
CA=f(CF), and CW=f(WH)
Exist complicated function of many variables relation as can be seen between each technological parameter of boiler for producing from above-mentioned relationship, be to adopt conventional instrument and meter for automation can't solve optimum operation technology under its complex conditions that is in various variable working condition, but can introduce above each functional relation in control software of the present invention easily takes all factors into consideration, handles and optimize, thereby can control the optimization coupling of parameters, the control of realization optimization reaches energy-efficient design object.Continue by communication converter (AC7 plate) between microcomputer and the interface case, both maximum distances can reach 5000 feet, so the interface case is loaded near the boiler on the spot, computer then can be installed in the control room.The universal product of the control interface (industrial control unit (ICU)) of dress OPT 022 series or similar standard in interface interface case can use.The digital quantity control interface of a PB16H+B1 and the analog quantity control interface of a PB16AH+B2 are housed in the interface case of OPT 022 series.Each sensing element and executive component and corresponding adaptation module thereof are the component units of electromechanical integration standard facility, also are the universal standard products that can choose in the market, and these all provide good hardware material conditions for enforcement of the present invention.
