Abstract
The utility model discloses a low-pressure steam utilizing system, which comprises a filter, a drain valve and a steam water separator, wherein the filter, the drain valve and the steam water separator are sequentially arranged in the direction of fluid flowing. A steam circuit of the steam water separator is connected with a steam bag, and a liquid circuit of the steam water separator is connected with a deaerator through a pneumatic adjusting valve. Soft water obtained through separation enters the deaerator directly, and transmission power is saved compared with pumping. Furthermore, steam condensate is high in temperature and free of oxygen, thermal deaeration is not further required, and consumed heat energy of the deaerator is saved. The low-pressure steam utilizating system can achieve a purpose of being efficient and making full use of energy.
Description
Technical field
The utility model relates to the UTILIZATION OF VESIDUAL HEAT IN technical field, and specifically a kind of low-pressure steam utilizes system.
Background technology
After at present domestic general steam step-by-step utilization recovery soft water technology is reduced to below the 0.4MPa for steam pressure uses, through the soft water condenser condenses, get into water softening tank, and then squeeze into the equipment that uses soft water with pump, the expense of soft water is produced in saving thus.But the soft water that this recovery system only produces Steam Recovery has carried out utilizing and has underused the waste heat of steam, and said soft water needs after the pump transmission is again through the oxygen-eliminating device thermal de-aeration, could get into water-softening plant, and this process also need expend the energy.Therefore, existing low-pressure steam utilizes system not reach efficiently, make full use of the purpose of the energy.
The utility model content
For solve existing low-pressure steam utilize system can not be efficiently, make full use of the technical problem of the energy, the utility model provides a kind of low-pressure steam to utilize system, to make full use of the energy of low-pressure steam.
The utility model is achieved in that low-pressure steam utilizes system to be included on the fluid flow direction installed filters, drain valve, steam-water separator successively; The vapour road and the drum of said steam-water separator join, and the liquid road of said steam-water separator joins through pneumatic control valve and oxygen-eliminating device.
The utility model adopts this structural design; High steam uses the steam reduces to below the 0.4MPa through gas utilization unit, and after presumable impurity particle filtered in to pipeline, drain valve was all exported ducted water through filter; Steam is kept here, to practice thrift the high steam consumption to greatest extent.Water under high pressure through behind the drain valve flashes off part steam, is mixed into steam-water separator with water, and the isolated steam of steam-water separator is delivered to the 0.4MPa of company drum, uses as heating or companion's heat.The isolated water of control steam-water separator is outwards carried after certain liquid level, directly delivers to oxygen-eliminating device through the control valve group and uses soft water as boiler.
This low-pressure steam utilizes system can make full use of Lowlevel thermal energy, and practices thrift the consumption of high steam.Separate the soft water that obtains in the utility model and directly advance oxygen-eliminating device, practiced thrift transmitting power than beating with pump.Again because of the higher oxygen-free of this steam condensate (SC) temperature, so thermal de-aeration has again been practiced thrift heat energy that oxygen-eliminating device consumes.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Shown in Figure 1; Low-pressure steam utilizes system to be included on the fluid flow direction installed filters 1, drain valve 2, steam-water separator 3 successively; The vapour road and the drum 5 of said steam-water separator join, and the liquid road of said steam-water separator joins through pneumatic control valve 4 and oxygen-eliminating device 6.
