The waste heat boiler consists of a steam drum, an evaporator, a superheater and a water heater, wherein one end of the water heater is connected with the steam drum, and the other end of the water heater is connected with the flash evaporator; the flash evaporator is connected with a deaerator and the turbine; the evaporator is connected with the steam drum; one end of the superheater is connected with the steam drum, and the other end of the superheater is connected with the turbine; the turbine is connected with the generator and further connected with the deaerator through a pipeline; the deaerator is connected with a water supply pump; and the water supply pump is connected with the water heater through a pipeline. Due to the existence of the flash evaporator, the low-grade heat of a boiler can be absorbed, the smoke discharging temperature is further lowered, the temperature at a smoke outlet of a waste heat boiler can be reduced to be below 90 DEG C, and the smoke waste heat fluctuating by a large margin can be actively adjusted by a generating system, so that the disturbance on a waste heat generating system can be greatly reduced, a role of balancing and stabilizing a system is played, and the generating efficiency of the waste heat boiler is improved.
Description
Technical field:
The utility model relates to a kind of flash evaporation electric installation of exhaust heat boiler boiler circuit.
Background technique:
Traditional single compression technology system is not owing to have flash vessel and loop; The influence of the narrow point of boiler, exhaust-heat boiler flue gas outlet temperature are not fully utilized for its heat of low grade residual heat flue gas of mainly being made up of hot air generally more than 170 ℃; System's generating efficiency is lower; And when stove waste heat supply temperature and flow increase suddenly, having no the heat that mode can absorbing redundant, the water that is arranged among the water heater conduit of boiler tail can be vaporized; Boiler drum level is uncontrollable, influences the normal operation of power generation system.
Summary of the invention:
The purpose of the utility model is to provide a kind of low temperature exhaust heat that effectively utilizes, and improves the flash evaporation electric installation of exhaust heat boiler generating efficiency.
The technical solution of the utility model is:
A kind of exhaust heat boiler flash evaporation electric installation comprises exhaust heat boiler, flash vessel, steam turbine, generator, and it is characterized in that: exhaust heat boiler is made up of drum, vaporizer, superheater, water heater; Water heater one end links to each other with drum, and the other end links to each other with flash vessel, and flash vessel links to each other with oxygen-eliminating device, steam turbine; Vaporizer links to each other with drum, and superheater one end links to each other with drum, and the other end links to each other with steam turbine; Steam turbine links to each other with generator; Steam turbine also links to each other with oxygen-eliminating device through pipeline, and oxygen-eliminating device links to each other with feed water pump, and feed water pump links to each other with water heater through pipeline.
Flash vessel is a vertical vessel, by inlet means, orifice fitting, orifice fitting, segregating unit etc. are formed under water.
The orifice plate that inlet means is processed by Austenitic Stainless Steel, baffle means and fixture are formed.
The beneficial effect of the utility model:
Exhaust heat boiler flash evaporation electric installation is because the existence of flash vessel; Fully absorb boiler low grade heat energy, further reduce temperature of exhaust fume, make the exhaust-heat boiler flue gas outlet temperature can be reduced to below 90 ℃; Fume afterheat power generation system to fluctuating widely is carried out active adjustment; Significantly reduce disturbance, play the effect of balance and stability system, and improved the exhaust heat boiler generating efficiency afterheat generating system.
