The multi-well-mouth single body assembled type natural gas heating furnace is suitable for large gas field wells, unique in structure, convenient to use and operate, safe and reliable.
Description
Technical field
The present invention relates to a kind of heating furnace that is applicable to large-scale gas field gas well, especially relate to the single combined gas heating furnace of a kind of many well heads.
Background technology
The traditional natural gas heating furnace generally adopts integral structure, and heat exchange coil mainly is installed in body of heater, has a plurality of well heads that the heat exchange coil of a plurality of correspondences just is installed in body of heater.Like this, can reduce the type of furnace, convenient management.But bad part with the natural gas of exploitation in contain corrosion factor, like chlorion, carbon dioxide etc., the equal heat exchanging coil pipe of these materials produces stronger corrosion.If there is the corresponding heat exchange coil of a certain well head corrosion failure to occur; The result can cause whole heating furnace to stop transport and rush to repair; And gas gathering station closes well operations because of the heating furnace blowing out causes all aerogenesis well heads, and this is a major accident, does not also overcome the device of the problems referred to above at present.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of large-scale gas field gas well, single combined gas heating furnace of a kind of many well heads that structure is unique, use is easy to operate, safe and reliable of being applicable to is provided.
The present invention realizes through following mode:
The single combined gas heating furnace of a kind of many well heads; It comprises the vacuum pressure controller that steam generator and its afterbody are installed; It is characterized in that: above-mentioned steam generator top all is connected with steam inlet pipeline and condensate return pipeline along being parallel with a plurality of heat exchanger units that the control of control system is independently arranged on the cylindrical shell length direction between each heat exchanger unit and the steam generator;
The top of said each heat exchanger unit is equipped with exhaust line, pressure vacuum gauge, blasting piece device and filler from left to right successively, and each heat exchanger unit one end is provided with the natural gas import, the other end is provided with gas outlet;
Said heat exchanger unit is 1～8.
The present invention has following effect:
1) structure unique, can heat for the natural gas of different well heads simultaneously: it comprises the vacuum pressure controller of steam generator and its afterbody installation heating furnace provided by the invention; It is characterized in that: above-mentioned steam generator top all is connected with steam inlet pipeline and condensate return pipeline along being parallel with a plurality of heat exchanger units that the control of control system is independently arranged on the cylindrical shell length direction between each heat exchanger unit and the steam generator; Exhaust line, pressure vacuum gauge and blasting piece device all are installed on each heat exchanger unit; A steam generator can be installed a plurality of heat exchanger units simultaneously; A plurality of heat exchanger units are combined through the steelframe platform, can heat for the natural gas of different well heads.
2) the single combined gas heating furnace structure of many well heads of the present invention; After heating furnace opened stove, at first saturated vapor was got into by the steam inlet pipeline, when the heat exchanger pressure vacuum gauge is shown to a certain malleation value; Open the valve of top exhaust line; Utilize swiftly flowing vapor stream, the air in the heat exchanger is carried away, be discharged in the surrounding environment.Steam discharge is closed the valve of exhaust line after a period of time.Needed the natural gas of heating again by natural gas import department feeding, what natural gas was walked in heat exchanger is tube side, undergoes phase transition with saturated vapor in the heat exchanger, and behind the condensing heat-exchange, the condensed water of generation flow back into the inner fluid space of evaporimeter by condensate line.
3) safe and reliable: the corresponding a plurality of monomer heat exchange units of a plurality of well heads of heating furnace provided by the invention, arrange vertically rationally that along evaporator tube length the evaporimeter afterbody is installed the vacuum pressure controller, guarantee the safety of evaporimeter.Heat exchanger unit and heating furnace evaporimeter are split-type structural, and each heat exchange unit has a style of one's own, all necessary monitoring and the protector of configuration.Even heat exchange coil generation corrosion failure occurs, steam off intake channel rapidly can not influence the natural gas heating of other well heads yet.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the right view of Fig. 1 of the present invention.
The specific embodiment
The single combined gas heating furnace of a kind of many well heads; It comprises the vacuum pressure controller 14 that steam generator 1 and its afterbody are installed; As illustrated in fig. 1 and 2: above-mentioned steam generator 1 top all is connected with steam inlet pipeline 10 and condensate return pipeline 9 along being parallel with a plurality of heat exchanger units 13 that the control of control system is independently arranged on the cylindrical shell length direction between each heat exchanger unit 13 and the steam generator 1;
The top of above-mentioned each heat exchanger unit 13 all is equipped with exhaust line 7, pressure vacuum gauge 6, blasting piece device 5 and filler 4 from left to right successively, and each heat exchanger unit 13 1 end is provided with natural gas import 8, and the other end is provided with gas outlet 3;
Above-mentioned heat exchanger unit 13 is 1～8.
As illustrated in fig. 1 and 2, the single combined gas heating furnace structure of a kind of many well heads of the present invention, main body is a steam generator 1, and the top is that monomer heat exchange unit 13 is also claimed heat exchanger, and two parts are connected with condensate return pipeline 9 through steam inlet pipeline 10.In operate as normal, steam generator 1 produces a large amount of saturated vapors, when needs heat the natural gas that a certain well head transports; Just can open the valve on the corresponding heat exchanger steam inlet pipeline 10, swiftly flowing steam gets into heat exchanger 13, and complications are advanced in heat exchanger; When the pressure vacuum gauge on the heat exchanger 13 6 is shown to regulation gauge pressure value; Can open the valve on the gas exhaust piping, utilize the flow at high speed characteristic of steam, heat exchanger 13 inner air are carried away.After reaching the regulation evacuation time, close the valve of unlatching.Need the natural gas of heating subsequently through natural gas import 8 feedings, after the saturated vapor in the heat exchanger 13 runs into the natural gas of cold conditions, undergo phase transition, the condensed water of generation flows back to the fluid space of steam generator 1 along condensate return pipeline 9.This process is the process of moving in circles.The heat exchanger that other well heads are corresponding also is to carry out phase-change heat-exchange according to this above-mentioned running.
When leaking appearred in heat exchange coil in the corresponding heat exchanger 13 of a certain well head, if pressure moment sharply increases, then blasting piece device 5 can produce explosion when reaching the force value of design, relieving pressure, the safety of protection housing and heating furnace integral body.After danger takes place, can close the valve at steam inlet pipeline 10 places under the heat exchanger 13, and can not influence the natural gas heating of other well heads.
Raise when certain reason causes steam generator 1 internal pressure, when reaching a certain design load, the vacuum pressure controller 14 that is installed in afterbody will be opened steam discharge, the safety of protection steam generator.
When steam generator 1 during because of steam discharge or blowdown lack of water, can add water through the filler 4 of installing on the heat exchanger 13, avoid occurring lack of water and dryout danger.
