Problems solved by technology
Due to the failure of the water pump during operation, especially the feed water pump of the waste heat boiler of the reduction furnace, water supply and water cutoff often occur, and there are potential safety hazards in operation
Although it is possible to connect the waste heat boiler of the bottom blowing furnace and the waste heat boiler of the reduction furnace in series, the connection in series will affect the normal operation of the bottom blowing furnace

Embodiment Construction
[0010] The content of the present invention will be described below with specific embodiments in conjunction with the accompanying drawings.
[0011] like figure 1 As shown, a waste heat boiler water supply pipe network includes bottom blowing furnace waste heat boiler water inlet pipe 1, reduction furnace waste heat boiler water inlet pipe 2 and fuming furnace waste heat boiler water inlet pipe 3; The feed water pump 4 on the three water inlet pipes; the water inlet pipe 1 of the waste heat boiler of the bottom blowing furnace, the water inlet pipe 2 of the waste heat boiler of the reduction furnace and the water inlet pipe 3 of the waste heat boiler of the fuming furnace are used in pairs. The seam steel pipes are connected with a pair of check valves 5 which are reversely paralleled with each other.
[0012] In order to ensure the water replenishment of the waste heat boiler of the reduction furnace and the waste heat boiler of the fuming furnace, the check valve 5 connect...

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 [0001] The invention relates to a boiler water supply system, in particular to a waste heat boiler water supply pipe network. Background technique [0002] Bottom blowing furnaces, reduction furnaces and fuming furnaces used in the crude lead smelting industry are all equipped with waste heat boilers on the exhaust chimneys to cool the exhausted flue gas. These waste heat boilers work in a high-temperature environment and need to continuously replenish water into the boiler. In the prior art, the water supply systems of the waste heat boilers of the bottom blowing furnace, the waste heat boilers of the reduction furnace and the waste heat boilers of the fuming furnace are separated separately. Due to the failure of the water pump during operation, especially the feed water pump of the waste heat boiler of the reduction furnace, water supply and water cutoff often occur, which poses a safety hazard in operation. Although it is possible to connect the waste h...
