AI Technical Summary
The dust in the ash hopper of existing electrostatic precipitators is prone to caking during ash discharge, making cleaning difficult. In addition, conventional heating methods consume a lot of energy, which affects the smooth operation of production.
A waste heat collection and heating system is adopted, which uses the waste heat of high-temperature flue dust as a heat source. The system forms a closed loop through a storage tank, a pump, and heat exchange tubes to directly heat the ash hopper, thus avoiding additional energy consumption.
It reduces the operating energy consumption and cost of the dust removal system, prevents caking and blockage inside the ash hopper, and ensures normal ash unloading and dust removal efficiency.
