Abstract
The invention relates to a water supply pipe network of waste heat boilers. The water supply pipe network comprises a bottom-blowing furnace waste heat boiler water inlet pipeline, a reducing furnace waste heat boiler water inlet pipeline and a fuming furnace waste heat boiler water inlet pipeline, and further comprises three water supply pumps connected to the three water inlet pipelines respectively. Every two of the bottom-blowing furnace waste heat boiler water inlet pipeline, the reducing furnace waste heat boiler water inlet pipeline and the fuming furnace waste heat boiler water inlet pipeline are connected with a pair of oppositely-connected check valves through a seamless steel pipe. Safe running of the three waste heat boilers is stabilized, high practicality is achieved, the water deficiency accident caused by the failure of the water supply pump of any waste heat boiler is avoided, and the situation that production halts due to the failure of a waste heat boiler system, and consequently the production operation rate is influenced is avoided.
Description
Technical field
The present invention relates to the water system of boiler, particularly a kind of water supply network of waste heat boiler.
Background technology
Its exhaust chimney of the bottom convertor that lead smelt industry uses, reduction furnace and fuming furnace is all equipped with waste heat boiler, plays the effect that flue gas is discharged in cooling.These waste heat boilers are operated in hot environment, need constantly toward supplementing water inside boiler.The water supply system of the bottom convertor waste heat boiler of prior art, afterheat of reducing furnace boiler and fuming furnace waste heat boiler three is separated separately.Due to the failure cause of water pump in operation, particularly afterheat of reducing furnace boiler feed pump, often occurs that moisturizing is cut off the water supply, and there is the potential safety hazard run.Although can by bottom convertor waste heat boiler and the series connection of the afterheat of reducing furnace feed water system of boiler, series connection use can affect the normal operation of bottom convertor.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of water supply network of waste heat boiler, when any waste heat boiler feed pump fault, can guarantee that three boiler safeties are stablized, avoid because lack of water or equipment fault cause blowing out to affect productivity effect.
Technical scheme of the present invention: a kind of water supply network of waste heat boiler, comprises bottom convertor waste heat boiler inlet channel, afterheat of reducing furnace boiler water pipe and fuming furnace waste heat boiler inlet channel; Also comprise three feed pumps be connected on these three inlet channels; It is characterized in that: described bottom convertor waste heat boiler inlet channel, between afterheat of reducing furnace boiler water pipe and fuming furnace waste heat boiler inlet channel three, between two mutual with seamless steel pipe connect a pair reciprocal to and the check-valves connect.
In order to ensure the moisturizing of afterheat of reducing furnace boiler and fuming furnace waste heat boiler, stop valve that the check-valves that between described bottom convertor waste heat boiler inlet channel and fuming furnace waste heat boiler inlet channel, positive direction connects is connected; The check-valves that between described afterheat of reducing furnace boiler water pipe and fuming furnace waste heat boiler inlet channel, positive direction connects also is connected stop valve.
Use the present invention, when afterheat of reducing furnace boiler or bottom convertor waste heat boiler feed pump break down or moisturizing at need, fuming furnace waste heat boiler feed pump can be utilized in time to carry out moisturizing, guarantee afterheat of reducing furnace boiler or the safe operation of bottom convertor waste heat boiler.
Major advantage of the present invention is: stabilize three waste heat boiler safe operations, practical, avoid the feed pump fault because of any waste heat boiler to cause lack of water accident to occur, the fault that it also avoid because of afterheat boiler system causes stopping production, affects production operational availability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, mark is: 1 bottom convertor waste heat boiler inlet channel; 2 afterheat of reducing furnace boiler water pipes; 3 fuming furnace waste heat boiler inlet channels; 4 feed pumps; 5 check-valves; 6 stop valves.
Detailed description of the invention
Below in conjunction with accompanying drawing specific embodiment, content of the present invention is described.
As shown in Figure 1, a kind of water supply network of waste heat boiler, comprises bottom convertor waste heat boiler inlet channel 1, afterheat of reducing furnace boiler water pipe 2 and fuming furnace waste heat boiler inlet channel 3; Also comprise three feed pumps 4 be connected on these three inlet channels; Described bottom convertor waste heat boiler inlet channel 1, between afterheat of reducing furnace boiler water pipe 2 and fuming furnace waste heat boiler inlet channel 3 three, between two mutual with seamless steel pipe connect a pair reciprocal to and the check-valves 5 connect.
In order to ensure the moisturizing of afterheat of reducing furnace boiler and fuming furnace waste heat boiler, stop valve 6 that the check-valves 5 that between described bottom convertor waste heat boiler inlet channel 1 and fuming furnace waste heat boiler inlet channel 3, positive direction connects is connected; The check-valves 5 that between described afterheat of reducing furnace boiler water pipe 2 and fuming furnace waste heat boiler inlet channel 3, positive direction connects also is connected stop valve 6.
