Description
Technical Field
The utility model belongs to the technical field of the boiler slagging-off, a wet slag removal system scale control system of thermal power plant is related to.
Background
The slag isThe slag of the molten material generated after the high-temperature combustion of the boiler contains alkaline oxide substances such as calcium oxide, and after the slag enters the wet deslagging system, the alkaline substances such as calcium oxide are dissolved out in water. The pH of the slag water gradually rises and Ca2+The concentration is gradually increased, and HCO is inevitably generated in the continuous recycling process of slag water3 -To CO3 2-Thereby causing the wet deslagging system to produce CaCO3Scaling problems. With the increasingly severe environmental protection requirements of China and the issuance of policies such as 'ten items of water' in 2015, the zero discharge of waste water from power plants becomes the mainstream trend. At present, most thermal power plants adopting wet slag removal are still in China, and the partial power plants realize the non-outward discharge of slag water through the whole plant water saving and wastewater treatment and transformation at present and recycle the slag water in the system. However, in the power plant adopting wet slag removal, in order to ensure that the water temperature of the sealing water at the furnace bottom is lower than 60 ℃, an excessive water supplementing mode is mostly adopted, so that a large amount of slag water overflows and is discharged outwards, and therefore, the power plant realizes zero overflow of slag water by additionally arranging a slag water cooler and optimizing a system water supplementing mode.
CaCO along with gradual realization of zero-overflow transformation of slag water of power plant3The fouling problem becomes more and more pronounced. In a power plant additionally provided with a slag water cooler, slag water is recycled for a long time, and CaCO is formed on the surface of the slag water cooler3Scale and heat exchange efficiency are reduced, the water temperature of the sealing water at the furnace bottom is controlled within 60 ℃, the water supplementing quantity is increased, the water supplementing quantity is higher than the consumption quantity, and slag water overflows. In addition, a large amount of CaCO is generated in the pipeline of the wet deslagging system3The scale can cause the pipeline for conveying the slag water to become thin, the water pressure is increased, and the fault of the conveying pump and the cost energy consumption are easily caused. The chain of the slag conveyor can not be flushed due to the scaling of the pipeline, thereby affecting the normal operation of the slag conveyor and causing the shutdown in severe cases. In conclusion, the scale prevention of the slag water system becomes a problem which is urgently needed to be solved by a wet slag removal power plant.

Pollutants such as ammonia nitrogen, chloride ions and the like in the regeneration wastewater finally and completely enter a desulfurization system, so that the water quantity of the desulfurization wastewater is increased, and the concentration of the ammonia nitrogen is increased. Therefore, the current treatment method of the regenerated wastewater is not suitable.
