Description
Technical field:
The utility model relates to the sealing security facilities technical field of oil, chemical industry storage storage tank, refers in particular to a kind of external floating top tank sealingly secure and ensures system.
Background technology:
The sealing system of floating roof tank should not exist oil gas to reveal in theory, but tank diameter is larger, exterior float disc and the sealing whole body are oversize, in production run process, be subject to the impact of the various factors such as temperature, there will be tank body, floating plate and hermetically-sealed construction irregular deformation, there is inconsistency in these distortion, cause sealing and tank body position to occur local a small amount of leakage, leakage is a small amount of, but has potential safety hazard.
For solving the problem of first and second sealing system oil and gas leakage, first be to find leak site at operational process, pore size is revealed in exploration, judge amount of leakage, repair, adjust sealing system, strive accomplishing not reveal or revealing on a small quantity, and in the time that leakage cannot be avoided, still there is certain potential safety hazard in current safety measure, haves much room for improvement.
Utility model content:
The purpose of this utility model is to overcome the above-mentioned weak point of existing product, provides a kind of external floating top tank sealingly secure to ensure system.
The technical scheme that the utility model is realized its object employing is: a kind of external floating top tank sealingly secure ensures system, and it comprises:
Be arranged on the supplementary pipeline of the nitrogen being communicated with in external floating top tank, with tank inwall to the seal cavity between floating plate edge plate, oil gas suction channel, described nitrogen supplements pipeline and the rounded setting of oil gas suction channel and girth diameter is to being respectively equipped with some divergent shape arms outwardly, and nitrogen supplements the nitrogen outlet of pipeline, the air suctiton inlet of oil gas suction channel is all positioned at seal cavity;
Be arranged on external floating top tank outside, supplement with described nitrogen nitrogen buffer tank and the nitrogen header pipe line that pipeline is communicated with successively;
The air suctiton ventilator that is arranged on external floating top tank outside, is communicated with described oil gas suction channel;
Be arranged on several combustible gas monitoring alarms that external floating top tank is interior, be distributed in many places;
And, be arranged on the control setup of external floating top tank outside;
Wherein, described nitrogen supplement pipeline, oil gas suction channel and with in their arm, be communicated with in the pipeline that nitrogen supplements pipeline and nitrogen buffer tank and nitrogen header pipe line, be connected in the pipeline of air suctiton ventilator and oil gas suction channel electromagnetic valve is installed respectively; Described control setup is connected with described combustible gas monitoring alarm, air suctiton ventilator and electromagnetic valve simultaneously.
Further, a set of described control setup, air suctiton ventilator and nitrogen buffer tank can adopt mode in parallel to supplement pipeline, oil gas suction channel and the connection of combustible gas monitoring alarm respectively at the nitrogen in multiple external floating top tanks.Can monitor the sealingly secure of multiple external floating top tanks simultaneously.
The utility model judges oil and gas leakage and Real-Time Monitoring gas concentration by combustible gas monitoring alarm, information is fed back to control setup, in the time that gas concentration reaches certain value, control setup control air suctiton ventilator is extracted the oil gas in seal cavity out, control the supplementary seal cavity that enters of nitrogen simultaneously, thereby dilution gas concentration, gas concentration is remained at outside flammable or explosion hazard scope, solve one, the problem of secondary sealing system oil and gas leakage potential safety hazard, and adopt centralized control room operation, chain interlock, large-scale storage tank district is concentrated to protection, it is convenient to control.
