Description
Technical field
The present invention relates to Waste resources reused field, more particularly to a kind of steam feed pump steam exhaust recovering device.
Background technology
The steam feed pump steam discharge of steam power plant drains into low pressure oxygen-eliminating device, after low pressure oxygen-eliminating device temperature reaches rated temperature,
Steam feed pump cannot meet boiler feedwater pressure requirements, need to increase pneumatic pump throttle flow to meet feed pressure requirement.When
After reaching water supply requirement, just there are a large amount of steam to be discharged into air, on the one hand exhaust generates noise, on the other hand causes waste, influences
Economic indicator.
Invention content
Depleted of steam can be recycled, reduced in order to compensate for the shortcomings of the prior art, the present invention provides a kind of
Waste, the steam feed pump steam exhaust recovering device for increasing benefit for enterprise.
The present invention is achieved through the following technical solutions：
A kind of steam feed pump steam exhaust recovering device, it is characterised in that：Including heat exchanger, the air intake of the heat exchanger with
The steam exhaust outlet connection of steam feed pump, the external cooling water source of water inlet connection of the heat exchanger, it is cold that water outlet exports high temperature
But water, the cooling water source are used with high-temperature cooling water circulating repetition, and the steam condensate (SC) outlet of heat exchanger is connect with drain tank,
The drain tank is connect with low pressure oxygen-eliminating device.
Further, the heat exchanger is shell-and-tube heat exchanger.
The external cooling water source is to comprehensively utilize exhaust steam residual heat for sugar refinery softened water or starch softened water, can heat
Sugar refinery or starch factory softened water, reduce waste.
The drain tank is also equipped with detection device, and qualified water is sent into low pressure oxygen-eliminating device and is recycled after testing.
The beneficial effects of the invention are as follows：The steam feed pump steam exhaust recovering device of the present invention, simple in structure, reasonable design,
The purpose of energy-saving and emission-reduction is realized, cost has been saved for enterprise, suitable for promoting the use of.
Description of the drawings
The present invention will be further described below with reference to the drawings.
Attached drawing 1 is a kind of structural schematic diagram of steam feed pump steam exhaust recovering device of the present invention；
Attached drawing 2 is a kind of flow chart of steam feed pump steam exhaust recovering device of the present invention.
In figure, 1, steam feed pump, 2, heat exchanger, 3, cooling water source, 4, steam exhaust outlet, 5, air intake, 6, water inlet, 7
Water outlet, the outlet of 8 steam condensate (SC)s, 9 drain tanks, 10 low pressure oxygen-eliminating devices, 11 detection devices, 12 high-temperature cooling waters.
Specific implementation mode
Attached drawing is a kind of specific embodiment of the present invention.As shown in Fig. 1, the steam feed pump steam exhaust recovering device, packet
Shell-and-tube heat exchanger 2 is included, the air intake 5 of the shell-and-tube heat exchanger 2 is connect with the steam exhaust of steam feed pump 1 outlet 4, the pipe
The water inlet 6 of shell heat exchanger 2 connects external cooling water source 3, cooling water source 3 be for sugar refinery softened water or starch softened water, it is comprehensive
It closing and utilizes exhaust steam residual heat, sugar refinery or starch factory softened water can be heated, reduce waste, water outlet 7 exports high-temperature cooling water 12,
The cooling water source 3 is used with 12 circulating repetition of high-temperature cooling water, and steam condensate (SC) outlet 8 and the drain tank 9 of heat exchanger 2 connect
It connects, drain tank 9 is also equipped with detection device 11, and qualified water is sent into low pressure oxygen-eliminating device 10 and is recycled after testing.
The present invention is in use, the steam exhaust of steam feed pump 1 is recycled, using soft for sugar refinery softened water, starch
Change water as cooling water source, by steam cooling, while heating and softening water using for softened water water source, steam condensate (SC) is discharged into naturally
Drain tank 9 is sent into low pressure oxygen-eliminating device 10 after chemical examination is qualified, then enters Steam Turbine through boiler from low pressure oxygen-eliminating device 10,
It is again introduced into steam feed pump 1, is recycled.
After the present invention is applied, checked into steam flow gauge with steam feed pump, shell-and-tube heat exchanger can consume 10 ton hours
Steam, while starch factory, sugar refinery softened water are heated to 60 DEG C or more.According to the 7 tons of calculating of current ton coal gas production, per hour
1.43 tons of raw coal can be saved, raw coal is saved 7,520,000 yuan or so of fund, saved greatly for enterprise in year by 600 yuan of calculating of average price
Cost is measured, suitable for promoting the use of.
