Description

Oxygen-removing tower steam discharge recycle and reuse system
Technical field
The utility model belongs to deaerator exhaust recovery and utilization technology field, especially relates to deaerator exhaust recycle and reuse system of a kind of steam power plant.
Background technology
Thermal power plant adopts thermal de-aeration, and after the deoxygenation, incondensable gas drains into atmosphere by gland steam exhauster.In getting rid of the incondensable gas process, a part of steam is also together discharged, and these high-temperature steams are directly discharged, and not only produce noise pollution, and cause the waste of the energy and water resource.For economizing on resources and reducing environmental pollution, the steam power plant that has adopts receives energy device recovery section heat energy; What have is provided with condenser, utilizes after steam is condensed into distilled water again.These methods can be carried out partially recycled to energy entrained in the deaerator exhaust and steam, but exist inefficiency, shortcoming such as recovering effect is relatively poor.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of organic efficiency height, can reclaim the recycling system of heat energy and steam in the deaerator exhaust simultaneously.
For solving the problems of the technologies described above, the utility model comprises the oxygen-eliminating device that is communicated with pipeline, heat-exchanger rig and condenser hot well, its design feature is to be provided with water collector between heat-exchanger rig and condenser hot well, described heat-exchanger rig is a water heat exchanger, this water heat exchanger is provided with air intake, condensation-water drain, water inlet and delivery port, the water collector water inlet pipe is communicated with the condensation-water drain of heat-exchanger rig lower end, water collector is communicated with the condenser hot well through the water collector outlet pipe, the condenser hot well is communicated with the water inlet of heat-exchanger rig by the hot well outlet pipe, and the hot well outlet pipe is provided with condensate pump; The air intake of heat-exchanger rig is communicated with oxygen-eliminating device through the deaerator exhaust pipe, and the delivery port of heat-exchanger rig is communicated with oxygen-eliminating device through the oxygen-eliminating device return pipe.
Described water collector is a water collect tank, and water collect tank is provided with electric pole type liquid level monitoring device, liquid level gauge and exhaust outlet.
Described heat-exchanger rig is board-like water heat exchanger.
The beneficial effects of the utility model are: because the utility model is provided with oxygen-eliminating device, heat-exchanger rig, water collector and the condenser hot well that is communicated with pipeline, the high-temperature steam that oxygen-eliminating device is discharged enters heat exchanger after heat exchange becomes condensate water, enter water collector then, behind the condensate water hot well, because hot well is a vacuum state, under the pressure differential effect, condensate water is pumped in the hot well, condensate water is squeezed into heat exchanger by condensate pump, enters into oxygen-eliminating device after heat exchange heats up, and realizes recycling.In whole circulation, vapour, water pass through the hydro-thermal heat exchanger simultaneously, and condensed water and high-temperature steam fully carry out heat exchange, in the heat, make steam be condensed into water rapidly in absorbing steam discharge, heat exchange is abundant, the efficient height has energy-conservation source and the recycling advantage that realizes water resource.Water collector is provided with electric pole type liquid level monitoring device, can realize Long-distance Control to water level in the water collector, increases work efficiency.
