Background
After the sintering mixture is ignited and sintered on a sintering machine, a sintering cake (700-800 ℃) is discharged from the tail of the sintering machine to a circular cooler for cooling, heat carried by the sintering cake exchanges heat with air blown in by a cooling fan in the cooling process, the sintering cake is cooled to below 120 ℃ and enters a screening system, high-temperature waste gas (300-500 ℃) after heat exchange is recovered by a smoke hood and then enters a waste heat boiler to generate medium-pressure and low-pressure steam, the medium-pressure and low-pressure steam is conveyed to a turbine and generator unit for power generation through a pipeline, or the medium-pressure and low-pressure steam is conveyed to the turbine through a pipeline to drag a main exhaust fan for acting. The system is composed of two parts of thermodynamic subsystems, namely a waste heat boiler thermodynamic system and a steam turbine thermodynamic system, no matter the steam is used for generating power or dragging the main exhaust fan. The two systems are connected through components such as a pipeline, a valve and the like.
At present, medium-pressure and low-pressure steam generated by an exhaust-heat boiler is discharged into a condenser to be cooled into condensate after the steam turbine works, and then is conveyed to a boiler water preheater interface through a condensate pump. Because the condenser hot well water level and the low-parameter drum water level can all fluctuate in the system operation process, the turbine thermodynamic system and the waste heat boiler system are connected only through the pipeline and the adjusting valve component, the low-parameter drum water level of the boiler can be influenced by adjusting the condenser hot well water level, and the low-parameter drum water level of the boiler can be influenced by adjusting the condenser hot well water level. When the liquid level of the heating well and the steam drum is regulated, small-amplitude regulation is needed, and difficulty is brought to operation.
The present utility model proposes a new solution to the above-mentioned problems.

Above-mentioned sintering waste heat recovery system's soda balance control system has following beneficial effect:
when the liquid level of the condenser hot well is lower, the regulating valve group of the condensed water at the outlet end of the second pump body on the circulating pipeline is opened, and the condensed water in the circulating pipeline enters the condenser hot well to raise the liquid level of the hot well. The flow on the main pipeline of the condensed water is correspondingly reduced, the water quantity entering the container is reduced, but because the container has the stored condensed water quantity, the condensed water quantity of the container sent to the boiler economizer can be unchanged, the height of the liquid level of the steam drum on the boiler side and the steam-water system thereof are not influenced, each valve group on the steam-water pipeline on the boiler side can not act, the normal work is kept, and the two systems are relatively independent and are not influenced each other.
