Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As shown in Figure 2, the centralized device of the gas pipe line of the first embodiment of the present invention comprises: liquid header 8 along the bearing of trend of gas pipe line 9 and extend, and is arranged on gas pipe line 9 belows, also comprise at least one liquid pipe 10 down, be communicated with gas pipe line 9 and liquid header 8.Liquid although it is a lot of to influence the normal factor of using of water seal, comprises temperature, vapor pressure, water supply etc. to liquid header 8 by concentrating down, adopts so centralized discharge opeing liquid seal device to make the fluid-tight process be convenient to management, and energy-conservation.
Preferably, the centralized discharge opeing liquid seal device of this gas pipe line also comprises liquid sealing pipe 12, is connected with the tapping end of liquid header 8, has the structure of the centralized discharge opeing liquid seal device of fluid-tight.Such structure only uses a liquid sealing pipe 12 to get final product, and has saved the liquid of fluid-tight, has reduced the generation of waste water.
Preferably, the liquid feeding end of liquid header 8 is connected with the media fluid pipeline.Because water seal will be done the heating measure, usually adopt the live steam heating pipe, heat liquid in the water seal, so will consume a certain amount of steam, in the time of in the winter time, for preventing that steam tube from freezing, also to open big vapour amount and guarantee to pass the winter safely, summer is when using, water seal consumes about 0.5 ton/day of steam flow, winter is when using, about 1.5 tons/day of steam consumption, nearly 300 tons/year with steam flow of water seals 1 year.The use of live steam simultaneously, the steam condensate of bringing into is contaminated, generates waste water, has continual water seal moisturizing to strengthen the generation of wastewater flow rate (400 tons/platform year) again.Every water seal year nearly 700 tons/year of waste water production.Cause follow-up sewage load very big like this.And the waste water of the equipment of employing is taken away waste liquid as media liquid, the one, and media liquid has brought heat, makes pipeline warm, prevents the condenses thickness; The 2nd, relatively large media liquid plays the effect of flushing pipe; The 3rd, play the effect that replenishes U type fluid-tight liquid automatically.Can not produce extra waste water, environmental protection and energy-conservation.
Preferably, the liquid feeding end of liquid header 8 is provided with flow control valve 20, and liquid header 8 liquid feeding ends are introduced media liquid, with the quantity of flow control valve 20 controlling liquid, guarantee that the heat that liquid brings can guarantee that pipeline does not freeze winter, flowing liquid also can in time be taken away discharge opeing.Liquid header 8 tapping ends enter selected liquid bath, all can as sloptank, the ground groove of mechanizeding ammonia clarifying groove or near same liquid character.
Preferably, liquid header 8 is arranged in the same longitudinal plane with gas pipe line 9, and following liquid pipe vertically is provided with 10, and so more convenient condensed fluid that is provided with is discharged.The vertical pipe section is short as far as possible, can prevent that like this pipeline is long, and condensate temperature reduces, and causes obstruction.
Preferably, first end of liquid pipe 10 is connected to gas pipe line 9 by first valve 13 under each, second end connects liquid header 8 by second valve 14, also be provided with the purge vapor arm 15 that is communicated with vapor source between first valve 13 and second valve 14, purge vapor arm 15 is provided with the 3rd valve 16.Can realize steam soaking work up and down by controlling two valves, keep pipeline unobstructed, be beneficial to discharge opeing.
Referring to Fig. 3, show the structural representation of the centralized device of gas pipe line according to another embodiment of the invention.9 of gas pipe lines are provided with intermediate equipment 18, and the outlet end of the gas pipe line 9 of connection intermediate equipment 18 both sides and the following liquid pipe 10 of liquid header 8 also is provided with auxiliary liquid sealing pipe 17, is connected with liquid header 8 via auxiliary liquid sealing pipe 17.Auxiliary liquid sealing pipe 17 is provided with the auxiliary liquid inlet pipe 19 that is communicated with described auxiliary liquid sealing pipe 17.Because of pipeline enclosure has equipment, gas pipe line 9 pressure are unbalanced, so not only will will introduce media liquid at liquid feeding end, and the pressure difference of equipment 18 both sides and other following liquid pipes 10 is bigger, for preventing the coal gas conducting, so need auxiliary liquid sealing pipe 17 fluid-tights and liquid header 8 isolation, auxiliary liquid inlet pipe 19 is provided with valve, auxiliary liquid sealing pipe 7 will be supplied with the circulation flushing liquor as media liquid separately, and its fluid-tight design height is a basis with the maximum pressure differential between each drainage point.Liquid header 8 tapping ends still will be provided with the fluid-tight of U type pipeline, height liquid seal with the maximum pressure of gas pipe line as design considerations.The concentrated discharge opeing design of many drainage points different pressures if each drainage point can be connected by sequencing, also can be taked following design, to reduce the inlet quantity of media liquid, convenient management.
Preferably, liquid header 8, liquid sealing pipe 12 and following liquid pipe 10 all are provided with thermal insulation layer, can make pipeline warm, prevent that the condenses thickness is difficult for discharging.In the use, can judge the pipeline working condition by measuring or touch the tube wall temperature of vertical liquid pipe 10 down and other terminal pipelines.
Original in addition water seal arrangement has exhaust stack 6, and pollution gas such as ammonia, hydrogen sulfide, hydrogen cyanide cause pollution of atmosphere from the unordered discharging of exhaust stack; Water seal is semi-enclosed, causes easily that when misoperation water seal emits liquid, and phenol water overflows polluted soil.And the totally enclosed fluid-tight of employing of the present invention does not have waste gas to discharge, environmental protection very.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
