Abstract

An auxiliary device for insufficient load of an air cooling island of an air separation plant in summer comprises a condenser which is arranged at a certain height and has a height difference with a condensed water tank, wherein the steam inlet of the condenser is connected into the main pipe of the outlet of a steam turbine through a steam flooding pipeline, while the condensed water outlet thereof is connected to the condensed water tank; the cold source inlet of the condenser is connected to the water return pipes of an air compressor and a supercharger, while the cold source outlet thereof is connected to the water-return main pipes of the air compressor and the supercharger; an extraction opening which is connected to the air extractor of the previous air cooling island is arranged at the middle part of the condenser; an electric goggle valve and an electric butterfly valve which are capable of switching off the steam flooding pipeline when the device is stopped are arranged within the steam flooding pipeline; the condenser is arranged at a certain height by means of a steel frame and has a height difference with the condensed water tank so that condensed water is capable of automatically flowing into the condensed water tank. The auxiliary device allows the air separation plant to operate under rated working conditions throughout the year, thereby meeting the requirements of normal production.

Description

Servicing unit when a kind of air separation plant air cooling island summer is underload
Technical field
What the present invention relates to is that a kind of air separation plant air cooling island that is directed against is when summer; Owing to environment temperature raises the air cooler cooling effect is reduced; Make whole air cooling island underload; Cause air separation plant not satisfy declared working condition and influence the situation of its normal operation, it is transformed and the covering device that increases, belong to the heat transmission equipment technical field.
Background technology
Because the NORTHWEST CHINA most of areas all belongs to the lack of water arid area, so general air separation plant steam turbine all adopts the air cooling, but because northern specific climate condition; The four seasons temperature difference is big, has brought very big difficulty for the design of air cooler and normal operation, takes all factors into consideration from economy and usability; The general employing designed air cooler by year-round average temperature, like this, and when summer; Weak effect will appear in air cooler, underload, the situation that equipment can't normally move.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists; And provide a kind of in order satisfy to produce needs, the air cooling island is undergone technological transformation, when summer temporarily; Can incorporate the air cooling island into works together; To share the part load on former air cooling island, make air separation plant obtain declared working condition, satisfy the servicing unit when underload in air separation plant air cooling island summer of ordinary production needs.
The objective of the invention is to accomplish through following technical scheme; It includes one and places certain altitude and be formed with the condenser of difference in height with a condensation water tank; The steam inlet of this condenser is connected among the house steward of steam turbine outlet through a general steam pipe road, and the condensation-water drain of condenser links to each other with said condensation water tank; The low-temperature receiver import of described condenser is connected in the return pipe of air compressor machine and supercharger, and is connected in the return main of said air compressor machine and supercharger in the low-temperature receiver outlet.
The middle part of said condenser is provided with the bleeding point of the former air cooling of connection island air exhauster; Be provided with the electronic eyes valve and the electric butterfly valve that when said device is stopped using, can cut off general steam pipe in the described general steam pipe road.
Described condenser places certain height with a steelframe, and is formed with the difference in height that can make condensed water flow into condensation water tank automatically with condensation water tank.
The present invention undergoes technological transformation to the air cooling island in order to satisfy the production needs---increase by a covering device, a condenser and supporting pipeline and control system; And utilize the cooling water source of the backwater of air compressor machine and supercharger as condenser; Return the return main of air compressor machine and supercharger after the process heat exchange, not extra increase cooling water source, interim when summer; Incorporating newly-increased condenser into the air cooling island works together; To share the part load on former air cooling island, make air separation plant obtain declared working condition, satisfy the needs of ordinary production.
The present invention compared with prior art, it can make air separation unit be under the declared working condition throughout the year and move, and satisfies the needs of ordinary production.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
To combine accompanying drawing that the present invention is done detailed introduction below: shown in Figure 1; The present invention includes one places certain altitude and is formed with the condenser 1 of difference in height with a condensation water tank; The steam inlet of this condenser 1 is connected among the house steward 7 of steam turbine outlet through a general steam pipe road, and the condensation-water drain 8 of condenser 1 links to each other with said condensation water tank; The low-temperature receiver import of described condenser 1 is connected in the return pipe 9 of air compressor machine and supercharger, and is connected in the return main 10 of said air compressor machine and supercharger in the low-temperature receiver outlet.
The middle part of said condenser 1 is provided with the bleeding point 11 of the former air cooling of connection island air exhauster; Be provided with the electronic eyes valve 5 and electric butterfly valve 6 that when said device is stopped using, can cut off general steam pipe in the described general steam pipe road 4.
Described condenser 1 usefulness one steelframe 2 places certain height, and is formed with the difference in height that can make condensed water flow into condensation water tank automatically with condensation water tank.In described general steam pipe road 4, also be provided with expansion joint 3, the tension failure that expands with heat and contract with cold and bring with solution to general steam pipe road.
Arrive when summer; The air cooling island is underload when influencing the normal operation of air separation plant; Just launch this device, at first open general steam pipe road valve, let a part of general vapour flow into condenser from general steam pipe; The condensation in condenser of general vapour, condensed condensed water rely on the difference in height of condenser and condensation water tank to flow in the condensation water tank automatically.
General vapour is in condensation process, and the part incoagulable gas utilizes the air exhauster on former air cooling island to extract out from the bleeding point at condenser middle part, incorporates former extract system into, makes whole system keep receiving common vacuum, guarantees the operate as normal of condenser.
Condenser low-temperature receiver of the present invention comes from the backwater of air compressor machine and supercharger; Return pipe from air compressor machine and supercharger picks out the pipeline entering condenser second month in a season respectively; After the condenser heat exchange, get back to return main separately more respectively, needn't increase extra cooling water source like this.
