Meanwhile, the air-seal heater can further play a role in lowering the pressure.
Description
Technical field
The present invention relates to a kind of converter waste heat generating system.
Background technology
UTILIZATION OF VESIDUAL HEAT IN is energy-saving and cost-reducing important directions, in existing commercial production, in cogeneration, the turbine generating system of a part adopts saturated vapor as generation driving force, both utilized (waste heat) boiler to produce saturated vapor and generates electricity, and effectively utilized residual heat resources. When generating, waste heat boiler produces saturated vapor and is directly entered the interior acting of Steam Turbine, but there is certain problem in such mode: saturated vapor is containing for moist steam, water content is higher, the moisture content produced in expansion process in steam turbine is many, it is therefore necessary to consider that steam turbine low-pressure grade blade band water dries measure; Due to a large amount of condensed waters that saturated vapor produces in acting process, when steam turbine loses load suddenly, accumulate in rotor surface, machine in standing part surface and piping, condensed water in the separator of particularly big volume can flash-off of steam, cause that steam turbine is jeopardously accelerated, affect the normal operation of steam turbine, reduce generating efficiency.
Summary of the invention
For overcoming the deficiencies in the prior art, it is an object of the invention to provide a kind of converter waste heat generating system, reduce the steam turbine internal condensation water yield, it is ensured that steam turbine is properly functioning, improve generating efficiency.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of converter waste heat generating system, including converter, heat exchanger, drum, thermal storage device, superheater, steam turbine, electromotor, condenser, sealing gland heater, condensate pump, oxygen-eliminating device, the steam (vapor) outlet of converter is connected with drum by heat exchanger, drum top is connected with thermal storage device air intake by pipeline, thermal storage device venthole is connected with steam turbine air intake by superheater, steam turbine is connected with electromotor, the road pipeline being connected with steam turbine successively with condensate pump, sealing gland heater, oxygen-eliminating device, feed pump, drum connects, the pipeline that steam turbine is connected with condensate pump is provided with condenser, leaving condenser water mouth is connected with cooling tower, cooling tower is connected with condenser water inlet by circulating cooling pump.
Compared with prior art, the invention has the beneficial effects as follows:
Being heated into superheated steam by superheater and reduce water content, and then become dry saturated steam, reduce the condensed water content of steam turbine, superheater can also improve specific steam enthalpy, improves generating efficiency; The condensed device condensation of steam after steam turbine acting generating, sealing gland heater heat exchanging part high-temperature steam return steam turbine, and the steam of the relatively low temperature of all the other condensations returns drum after oxygen-eliminating device deoxygenation, recycles, saving water resource. Meanwhile, sealing gland heater can also play the effect of decompression.
