Abstract
The utility model provides a combustion analyzing monitoring device of an oil field steam-injected boiler, which comprises an industrial control computer and a data collecting terminal. The industrial control computer is connected with the data collecting terminal through a signal line. The data collecting terminal makes collected electrical signals transmitted to the industrial control computer through the signal line. The industrial control computer sends an igniting operation signal to a boiler control panel according to the comparison between an oxygen content inside the flue gas and the oxygen content locally detected in a real-time manner. Specifically, when combustible gas exists in a flue, the oxygen content in the flue is then reduced; otherwise, the oxygen content inside the flue is equal to the oxygen content in the air. The oil field steam-injected boiler combustion analyzing monitoring device provided in the utility model is advantageous in that if the boiler control panel receives no control signal from the industrial control computer during a boiler purging process, the boiler is always in a purging state and emits an acousto-optic alarm signal; the igniting program only begins when a control signal is received; and an early warning function about the combustible gas inside a combustion chamber is thus achieved.
Description
Technical field
The utility model relates to the control device of oilfield gas injection boiler operatiopn.
Background technology
The capital equipment that uphole steam generator is produced as oil-field thick-oil, its annual energy consumption is considerable.Improving the thermal efficiency and the efficiency of combustion of injection boiler, is the problem that each enterprise must consider.In order to improve the burning of injection boiler, improve the thermal efficiency, guarantee the safety of operation, the method that adopts usually is: the 1st, strengthen operator's technical training, guarantee the efficient burning and the security of operation of injection boiler through lift technique quality.The 2nd, through increasing the purge time of combustion chamber, solve the fuel gas that possibly exist in the combustion chamber.The 3rd, improve burning through in fuel, adding chemical assistant, promote efficiency of combustion.Be in operation in above three kinds of modes and have following problem: the 1st, because the difference of operating personnel's technical quality, the result difference that burning is regulated is bigger, seldom can reach optimum state.The 2nd, through increasing the purge time of combustion chamber, can not guarantee real purging " totally ", operating easy generation second-time burning accident.The 3rd, though can improve burning through adding chemical assistant, the factor that influences efficiency of combustion is more, and is very difficult in order to be effective, also increased the input of cost simultaneously.
Summary of the invention
The purpose of the utility model is to provide a kind of before igniting, the detection to send the analysis monitoring device that allows ignition signal when oxygen content is qualified in the flue outlet place air.
The utility model provides a kind of oilfield gas injection boiler combustion to analyze monitoring device; It is characterized in that: mainly comprise industrial computer and data collection station; Industrial computer is connected with data collection station through holding wire, and data collection station is delivered to industrial computer with the signal of telecommunication that collects through holding wire, and industrial computer is according to the comparison of flue gas oxygen content with the air oxygen content of local actual measurement; In flue, contain fuel gas, the oxygen content in the flue will reduce; Otherwise when not having fuel gas in the flue, the oxygen content in the flue will be consistent with airborne oxygen content, promptly in the flue gas in oxygen content and the air oxygen content identical, industrial computer sends the ignition operation signal just for the boiler control panel.
Monitoring device is analyzed in the oilfield gas injection boiler combustion that the utility model provides, and its data collection station can comprise oxygen content detector and the temperature sensor in the boiler flue, and the oxygen content detector is connected with industrial computer through holding wire respectively with temperature sensor.
Monitoring device is analyzed in the oilfield gas injection boiler combustion that the utility model provides, and its holding wire is outer can be surrounded by shielding, in order to avoid the mV level signal of flue gas acquisition terminal output is disturbed.
Monitoring device is analyzed in the oilfield gas injection boiler combustion that the utility model provides; Its advantage is: during boiler purges; Has only the control signal that receives industrial computer when the boiler control panel; Boiler is in the purging state all the time, and the concurrent visual alarm of speaking realizes that ignition of the boiler is preceding to the fuel gas warning function in the combustion chamber.
