Background
Due to the rising energy price, the domestic coal price is greatly increased, and the energy conservation and the enterprise cost reduction become the most urgent tasks of each enterprise. And a large amount of low-pressure steam and flash steam (dead steam) generated in the operation of a large amount of industrial boilers and power station boilers of enterprises are discharged outwards. In addition, in the process of using steam, many enterprises can generate a lot of low-pressure steam which is discharged due to process reasons, so that great energy loss and waste are caused, and the recovery economic value is huge.
At present, 60% of the steam exhaust and the condensed water in China are not recovered, and the total amount of the steam exhaust and the condensed water discharged as the waste steam/water is about 4.5 hundred million tons every year. If the waste steam with recovery value is reasonably recycled, the economic value is very obvious.
Open exhaust steam condensate recovery system is common recovery mode, uses open exhaust steam condensate recovery system can produce a large amount of steam, causes the loss in a large number of heat and demineralized water (demineralized water), and high temperature condensate passes through the flash distillation mode and becomes steam and low temperature hot water, and high temperature condensate can not obtain recycling almost. The recovery process of the open type exhaust steam condensate is shown in a figure 1, and the recovery mode has the characteristics of simplicity, no influence on steam equipment, stable operation of a condensate pipeline, no water hammer and the like. The defects of the method comprise the following four aspects:
A. a large condensate tank (or a reservoir) without pressure is required to be arranged to collect condensate, and the generated secondary steam is not utilized completely, so that waste gas pollution is caused;
B. in the process of collecting condensed water, air is mixed into a system by a condensed water tank (or a water storage tank) without pressure, so that the condensed water pipeline system is easily corroded;
C. because the condensed water collecting tank (or the water storage tank) does not have pressure, secondary pollution of the condensed water is easy to cause, and the water quality standard of the boiler is difficult to achieve;
D. because the condensed water in the condensed water tank (or the reservoir) is high-temperature water without pressure, the pump can generate vaporization phenomenon at the suction inlet of the pump body when the water pump runs, so that the cavitation of the pump is caused, and the service life of the pump impeller is further influenced. To ensure the pressure at the pump inlet, only the condensate tank (or reservoir) is raised or the pump mounting height is lowered.
