Abstract
The present invention discloses a method for controlling flare pilot lamp, and is characterized by that it adopts the pressure of discharged flare tail gas, flow combustile gas content and flare flame detector as ignition signal, and according to the user's setting value makes the control of ignitor processor and ignition valve processor so as to implement No.1 flare system monitoring mode when the pilot lamp and flare are being in blanking state generally and production equipment has combustile gas discharge due to process change and the combustible gas has need of combustion, and implement No.2 flare system monitoring mode when the flare is in combustion state, pilot lamp in in blanking state and when the idle is produced or flare is blanked and the pilot lamp and flare are lighted.
Description
Technical field
The present invention relates to a kind of method of controlling torch altar lamp which burns day and night.
Background technology
Flare system is the important safety in production device of oil plant and petrochemical plant, be the last safety devices of emergency blow-down in the whole process of production, during the process units ordinary production, torch generally has two kinds of methods of operation, a kind of is the long-term combustion system of torch, and a kind of is that torch is in usually and extinguishes state and the process units technological fluctuation has the mode of fuel gas when discharging burning.In existing design, for guaranteeing the safe operation of flare system, the altar lamp of above-mentioned two kinds of method of operation torches all is to burn throughout the year.Flare system generally links to each other with process units by pipeline and away from process units.Flare system mainly adopts the fire tube sparking mode at present, and the duration of ignition is longer, be difficult for lighting, and altar lamp extinguishes the bigger potential safety hazard of back existence under adverse circumstances.Do not find the method for effective control torch altar lamp which burns day and night by retrieval.
The purpose of this invention is to provide a kind of method of controlling torch altar lamp which burns day and night, solve under the different process situation, torch altar lamp which burns day and night is extinguished with fuel savings.
Summary of the invention
The present invention is achieved in that according to the process units state of arts, a kind of is to be discharged into the pressure of torch tail gas, temperature, flow, current signals such as combustible gas content are converted to standard signal through transmitter and are delivered to program control instrument, for the program control instrument monitoring analysis, program control instrument compares the signal and the setting value of gathering, the output state language, alarm signal, and to igniter, lighting valves etc. are controlled, realize altar lamp, the 1# torch is in usually and extinguishes state and mode that technological fluctuation control effectively when having fuel gas discharging to need burning, and the burning torch is the 1# torch.
Another kind is the system monitoring of the long-term combustion system of torch---during the process units ordinary production, when torch is in fired state after testing, altar lamp is in and extinguishes state, and take place to stop or torch during because of unplanned extinguishing when flare system, then light altar lamp to guarantee tail gas normal combustion, safety dumping.
The process units discharge tail gas enters water sealed tank 2 in 1# torch 5,6 burnings of 2# torch by exhaust pipe 1, fuel control valve 9 is installed on altar lamp 7 gas supply pipelines 10, the data owner that enters program control instrument 17 will be from the flowmeter 19 on 1. exhaust pipes 1, when the flow upper limit is higher than 12000Nm
3/ h or be lower than 3500Nm
3During/h, light a fire automatically by signal line 12 realization 1# torches.When the flow upper limit is lower than 12000Nm
3/ h or be higher than 3500Nm
3During/h, light a fire automatically by signal line 12 realization 2# torches.2. combustible-gas detector 18, when organic concentration in the fuel gas reaches 5% when above, realize that by signal line 13 1#, 2# torch light a fire automatically.3. the torch monitor 4, when torch flame should normal combustion and when extinguishing for some reason, realize that by signal line 14 1#, 2# torch light a fire automatically.4. differential manometer 3, when water sealed tank pressure reduction is higher than 500mmHg, light a fire automatically by signal line 15 realization 1#, 2# torch.5. should move and when all not moving when flowmeter 18, fuel gas monitor 17, torch monitor 4, differential manometer 3, realize that by signal line 16 1#, 2# torch light a fire automatically.
Good effect of the present invention is: extinguish state and the pressure of process units technological fluctuation 1# torch of combustion system when the fuel gas discharging is arranged by the 2# torch of the long-term combustion system of torch and torch are in usually, temperature, flow, combustible gas content etc. carries out monitoring analysis, make altar lamp can light the control of this complex working condition of torch automatically as ignition signal, torch altar lamp which burns day and night is in after igniting and extinguishes state simultaneously, realized the automatic policer operation of flare system, improved the security of flare system operation, flare system ignition success rate height, overcome the problem of other ignition system fluctuation of service, save the fuel of torch altar lamp which burns day and night, controlled environmental pollution.
