Description
Technical field
The utility model relates generally to that torch gas in the industries such as being applied to petrochemical industry, oil, oil field, oil refining, chemical industry, metallurgy reclaims and the water-sealing valve system of releasing system safe operation.
Background technique
At present; in petrochemical industry, oil, oil field, oil refining, chemical industry, metallurgy industry; all can produce a large amount of waste gas; directly in atmosphere, do not discharge as treated; then can serious environment pollution, the waste gas with value generally all carried out recycle, to improve resource utilization; and to carrying out burning and exhausting when breaking down in value or the callback course, to guarantee normal operation and the protection of the environment of reclaiming system.Especially when reclaiming system broke down, it was to guarantee one of requisite measure of safety that the torch gas that produces is directly discharged burning.People have designed the normal operation that various safety installationss guarantee flare gas recovery system for this reason, and wherein modal method has valve control reclaiming system and water seal control reclaiming system (ZL200420079150.8).Although the control reclaiming system of utilizing valve to form can reclaim torch gas on request, less on the impact of original system back pressure, its Security is relatively poor, in case when breaking down, instrument wind mistake gas or valve will have a strong impact on safety dumping, and automatization level is low; The advantage of water seal control reclaiming system is safety, reliable.But when former releasing system increases the back pressure of a fixed amount, just require the safety valve that original system is connected, the throughput of Decompression valves that certain requirement is arranged, when discharge amount is larger, the water yield in the water sealed tank is few, outer water supply flow is also being supplied in short-term, so can't water seal be opened or be shut in the utmost point short time, when the discharging burning, easily water is brought in the flare tip simultaneously, even when the molecular sealer impeded drainage, can form the high-altitude water seal, cause piping vibration, will consist of certain potential risk to the safe operation of whole system and even flare tip.
Summary of the invention
For the defective that exists in the prior art and technical problem, the utility model provides a kind of torch gas of fast automatic moisturizing to reclaim automatically control water-sealing valve system of discharging, can be implemented in the torch gas flow and guarantee that flare gas safe reclaims the function of discharging when excessive.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of torch gas of fast automatic moisturizing reclaims automatically control water-sealing valve system of discharging, comprise cylindrical shell, water seal cylinder, torch gas inlet tube, torch gas outlet and automatic water storage tank, described water seal cylinder is located at inner barrel, described torch gas inlet tube stretches in the water seal cylinder, described torch gas outlet is located on the cylindrical shell and with the inner barrel cavity and communicates, described water seal cylinder and inner barrel cavity are by pipeline communication, and this pipeline is provided with the first automatic valve; Described automatic water storage tank is located at the cylindrical shell top, and is communicated with the water seal cylinder by pipeline, and this pipeline is provided with the second automatic valve.
As improvement, the torch gas inlet tube below in the described water seal cylinder is provided with heater; Be provided with heater in the described automatic water storage tank.
Further, described cylindrical shell is provided with at least 1 level meter and 1 dewatering outlet.
Further, described the first automatic valve is connected with pressure transducer, and this pressure transducer is located in the torch gas inlet tube; Described water seal cylinder and automatic water storage tank are equipped with anti-vibration member.
Beneficial effect: with respect to prior art, the utlity model has following advantage: have duplicate protection, the water-sealing valve control reclaiming system of utilizing the utility model to form has torch gas and reclaims stable, simple in structure, safe and reliable characteristics, especially during large discharge amount or when instrument wind breaks down, still can guarantee safety dumping, from having ensured in essence the safe operation of flare gas recovery system; Can adapt to the requirement of various discharging frequencies and discharge amount, economic benefit and social benefit are remarkable, can apply to the industries such as petrochemical industry, oil, oil field, oil refining, chemical industry, metallurgy.
