Description
Technical field
The utility model relates to a kind of hydrophobic heat recovery system.
Background technology
As everyone knows, thermoelectric industry unit peak valley operation, the start-stop of equipment switching device is very frequent; In therrmodynamic system,, carry out heating coil as long as there have equipment switching and start and stop just to need to open pipeline to be hydrophobic; Hydrophobic must opening before equipment does not reach rated temperature and pressure, great amount of heat is carried in all hydrophobic meetings, and the hydrophobic hot break value of medium temperature and medium pressure is up to 1400KJ/kg; Owing to can not reclaim, can only carry out emptying, cause a large amount of wastes and noise.And local steam power plant thermic load is unstable, causes the deaerator level fluctuation bigger, and demineralized water was nervous when thermic load was high, and when load was low, the high outwards spilling water of deaerator level if do not reclaim spilling water, will cause the significant wastage of demineralized water.Add holding at high price of coal, local thermoelectric industry is suffered untold misery, scrap build, the energy-conservation unique selection of having taped the latent power and having reduced cost into local thermoelectric enterprise.
Summary of the invention
To above-mentioned prior art; The utility model provides a kind of hydrophobic heat recovery system, and it is that the inventor is actual according to the equipment of oneself, to the hydrophobic transformation of carrying out of heat power equipment; Various hydrophobic; The pipeline such as oxygen-eliminating device spilling water that promptly discharges water is connected in the container, reaches the purpose that reclaims demineralized water, and retrieves to heat demineralized water through steam preheating and reach energy saving purposes.
The utility model is realized through following technical scheme:
A kind of hydrophobic heat recovery system; Comprise at least one flash vessel, receive ability device and drain tank, wherein, the discharge outlet of flash vessel is communicated with drain tank; The steam drain place of flash vessel and drain tank is provided with water seal arrangement; Be provided with jet chimney between steam drain and the water seal arrangement, also be provided with jet chimney on the drain tank, jet chimney can be communicated with by device with receipts.
During use; According to different equipment pressure ratings, heat distribution pipeline hydrophobic is divided into different hydrophobic female pipes, with the unified flash vessel that is connected to different brackets of hydrophobic female pipe; Drain tank is communicated with oxygen-eliminating device; Establish two drainage pumps (fortune one is equipped with) on the connecting pipeline, simultaneously the oxygen-eliminating device spilling water is connected to drain tank, will receive and to be communicated with unit condensate or demineralized water pipeline by device.During work, the water in the heat distribution pipeline drains in the drain tank and reclaims, and steam then gets into through jet chimney and receives the ability device; Unit condensate or demineralized water also get into receipts ability device simultaneously, and the ability device is inner receiving, the steam that steam turbine condensate or demineralized water cooling are got into; Through receiving inner atomising device, the dehydration plate of ability device; Make the abundant and vapor mixing of condensate or demineralized water, the heating demineralized water, and reach purpose energy-conservation and the elimination thermal loss; Condensate after heating or demineralized water get into drain tank then, are driven into oxygen-eliminating device through drainage pump, behind oxygen-eliminating device, get into boiler through feed pump again and use.So, promptly recyclable a large amount of demineralized water also can reclaim the steam preheating that flash vessel is arranged, and also can heat demineralized water through recovered steam, and through measuring and calculating, the demineralized water temperature can improve about 20 ℃.
For letting the steam discharge of each flash vessel get into receipts ability device smoothly, the inventor of the utility model has done a lot of experiments, and each steam drain can not add door; Pressure is too high when preventing that equipment from operating suddenly, can normal emptying be unlikely to support bad water tank for guaranteeing steam, and can reclaim each steam discharge at ordinary times; The inventor is installed water seal arrangement according to water-seal principle additional at each steam drain place, can guarantee the recovery of pressure vapour; Can guarantee the safety of equipment again, through the operation of some months, through the check of various operating modes; Scrap build is extremely successful, reaches its intended purposes.
The utility model is installed water seal arrangement at each flash vessel steam drain, is connected jet chimney between the steam drain of each dewatering capacity-enlarging device and the water seal, and guiding to receipts to row to the steam of atmosphere can device; Steam receive mixes with the unit condensate in can device receive ability after, produce high-temperature water, high-temperature water entering drain tank; High-temperature water gets into oxygen-eliminating device through water pump then; Reach the purpose of comprehensive utilization, through calculating, it is considerable to reclaim benefit.
