Acquired data is transmitted by the data acquisition terminal to a processor of the industrial personal computer; operation and PID (Proportion-Integral-Differential) adjustment are carried out by the processor of the industrial personal computer so that signals are output to the electric actuator and the frequency converter; the fuel flow is changed by the electric actuator; and the rotation speed of the boiler blower is changed by the frequency converter so that the distributed air is changed, and the automatic adjustment of the combustion is realized. The combustion control device for the gas injection boilers in the oil fields has the advantages of correctly judging the combustion condition through using the online data acquisition terminal, automatically adjusting the fuel quantity and the distributed air in real time by the industrial personal computer according to the operation result and realizing the high-efficiency combustion.
Description
Technical field
The utility model relates to the control device of oilfield gas injection boiler operatiopn.
Background technology
The original combustion control mode of uphole steam generator is the ratio of manual adjustments fuel quantity and wind supply quantity, and mode of appearance such as the color of the effect of adjustment through observing flame, shape are confirmed.In order to guarantee the normal combustion of injection boiler, improve the thermal efficiency, the method that adopts usually is: the 1st, strengthen patrolling and examining of operator, pinpoint the problems at any time, regulate at any time.The 2nd, the air distribution amount of normal combustion mainly is that the mode through current limliting realizes.The 3rd, when fuel performance changes, need grope to set the various parameters of influence burning again.Be in operation in above three kinds of modes and have following problem: the 1st, because the difference of operator quality, burning is regulated untimely, causes waste of fuel and product quality defective.The 2nd, regulate wind supply quantity through current-limiting mode, the blower fan power consumption is basic not to be reduced, and moves uneconomical.The 3rd, boiler combustion parameter renegotiation new settings process time is longer, is prone to cause combustion instability.
Summary of the invention
The purpose of the utility model is to provide a kind of control device of oilfield gas injection boiler operatiopn, and in real time automatic fuel metering amount and air distribution amount realize high efficiency burning.
The utility model provides a kind of oilfield gas injection boil combustion control device; It is characterized in that: mainly comprise industrial computer, data collection station, YE and frequency converter; Data collection station is connected with industrial computer through holding wire; Industrial computer is connected with frequency converter with YE through lead, and frequency converter is connected with boiler blower.Data collection station is sent to the data that collect in the processor of industrial computer, and the processor of industrial computer carries out computing and PID (proportional-integral-differential) regulates, and outputs signal to YE and frequency converter; YE changes fuel flow rate, and frequency converter changes the rotating speed of boiler blower, thereby changes the air distribution amount; Realize the automatic adjusting of burning; And will continue image data and the oxygen content setting value compares, and form a closed-loop control, reach desired value up to burning.
The oilfield gas injection boil combustion control device that the utility model provides; Its data collection station can comprise the flowmeter of oxygen content detector, the thermometer in the boiler flue and boiler oil porch in the boiler flue, and the three is connected with industrial computer through holding wire respectively.
The oilfield gas injection boil combustion control device that the utility model provides; Its data collection station can also comprise boiler operatiopn state (preceding purging, igniting, little fire, big fire and post-purge) signalling means, and boiler operatiopn status signal device is connected with industrial computer through holding wire.Between purge stages, burn period and the little fire burns stage, fuel quantity is minimum before boiler, and oxygen content is higher, and the boiler-burner air door is in the complete shut-down state, avoids causing that because of air feed pressure is low combustion product gases turns back to air blast one side, forms tempering and damages burner.
The oilfield gas injection boil combustion control device that the utility model provides, its industrial computer can be connected through holding wire boiler control panel, and information such as processor output oxygen content, flue-gas temperature and the boiler thermal output of industrial computer show for the boiler control panel in real time.
The oilfield gas injection boil combustion control device that the utility model provides, its advantage is: through using the on-line data acquisition terminal, accurately judge combustion position, industrial computer is according to operation result, and in real time automatic fuel metering amount and air distribution amount realize high efficiency burning.
Description of drawings
Fig. 1 is the structure principle chart of oilfield gas injection boil combustion control device.
The specific embodiment
Oilfield gas injection boil combustion control device; Its structural principle is as shown in Figure 1; Comprise industrial computer (industrial computer) 1, data collection station 2, YE 3 and frequency converter 4; Data collection station 2 comprises the flowmeter and boiler operatiopn state (preceding purging, igniting, little fire, big fire and the post-purge) signalling means of oxygen content detector in the boiler flue, the thermometer in the boiler flue, boiler oil porch; Oxygen content detector, thermometer, flowmeter and boiler operatiopn state are connected with industrial computer 1 through holding wire respectively, and signalling means data collection station 2 is sent to the data that collect in the processor of industrial computer 1.
The oxygen content detector detects oxygen concentration potential, and oxygen concentration potential and oxygen amount 0-20.9% are to concern one to one, and promptly when oxygen content was 0, the corresponding output current of the oxygen concentration potential of detection was 4 mA; Oxygen content is 20.9% o'clock, and the corresponding output current of the oxygen concentration potential of detection is 20mA, changes out the 4-20mA standard signal through internal calculation.
At the big fire combustion phases, the processor of industrial computer 1 carries out computing and PID (proportional-integral-differential) regulates, and outputs signal to YE 3, frequency converter 4 and boiler control panel 6; 6 pairs of information such as oxygen content, flue-gas temperature and boiler thermal output of boiler control panel are given in real time and are shown, YE 3 changes fuel flow rate, and frequency converter 4 changes the rotating speed of boiler blower 5; Thereby change the air distribution amount; Realize the automatic adjusting of burning, and will continue image data and the oxygen content setting value compares, form a closed-loop control; Reach desired value up to burning, promptly flue gas oxygen content is between 3%～5%.
