Description
Technical field
The utility model relates to power plant steam thermal system, particularly relates to the retracting device of the condensed water in high temperature in steam thermal system.
Background technology
After the nineties, along with expanding economy, energy-saving and emission-reduction have become the problem of people's pay attention to day by day, and the recycling of power plant to the energy is also paid much attention to, and the reuse ratio of the energy is ranging in low level always has become the key factor of restriction power plant development.In power plant industrial production, mechanical part is that medium promotes acting thus drive electrical generators generating with steam, and the saturation water that the steam condensation after acting becomes, a part continues to enter boiler and uses, another part then carries out recycling, existing condensate-water polishing mode can not realize the airtight operation of condensate-water polishing, and always some flash steam is discharged to air, thus adds the heat-energy losses in power plant and the thermal pollution to air.
Utility model content
The purpose of this utility model is to provide a kind of heat-pump type high-temperature condensate retracting device, it can realize the sealing operation that condensed water in high temperature reclaims, make the recovery of condensate water unimpeded, flash steam pressurization is utilized again, effectively can reduce heat radiation and the flue gas loss of boiler.
The technical solution of the utility model is as follows: a kind of heat-pump type high-temperature condensate retracting device, comprise water collect tank, heat pump and water pump, heat exchanger is connected with water collect tank by pipeline, its connecting line is provided with drain valve, the condensate water of discharging from heat exchanger enters water collect tank by drain valve, carry out carbonated drink separation, flash distillation; One end of heat pump is connected with the top of water collect tank, and one end is connected with heat exchanger, and the flash steam in water collect tank is extracted out and boosted and sends into heat exchanger heat release again by heat pump; Water collect tank has automatic gauge, and for monitoring the water level of water collect tank, electric cabinet one end is connected with automatic gauge, and the other end is connected with water pump; The bottom of water collect tank is provided with outlet pipeline, and water pump is located on outlet pipeline.
In aforesaid heat-pump type high-temperature condensate retracting device, described heat pump is steam jet heat pump, flash steam can be extracted out, boosting recycling, quite a few heat can be reclaimed, and have structure simple, invest little, reliable, the thermal efficiency is high and the advantage of economize energy, water pump is anti-cavitation pump, centrifugal pump porch can be solved because producing pressure drop, saturation water components vaporize makes the problem of pump generation cavitation, especially can be implemented in the conveying of saturation water when drain valve quality is not good, steam loss increases and in steam water interface, steam proportion is larger.
In aforesaid heat-pump type high-temperature condensate retracting device, described drain valve is orifice-plate type drain valve or Shemostatic team trap, effectively can reduce the maintenance load of drain valve and extend its replacement cycle, thus saving substantial contribution.
Compared with prior art, the flash steam in water collect tank can be extracted out by the utility model, the pressure in water collect tank is reduced, thus makes the recovery of condensate water unimpeded, be conducive to the work of heat exchanger; Flash steam pressurization is utilized again, decreases than its liquefaction back boiler the energy that conveying consumes, thus decrease heat radiation and the flue gas loss of boiler, obtain obvious energy-saving effect; Extract flash steam out recycling, the requirement to drain valve or cancellation drain valve can be reduced, decrease the maintenance load of drain valve and extend its replacement cycle, thus can substantial contribution be saved.
