Description

Technical Field

[0001] The utility model relates to a steam purging technology, in particular to an anti-clogging steam purging device. Background Art

[0002] When the flue gas is discharged from the glass kiln, the temperature is as high as 500-550℃. It then passes through the waste heat boiler of the power plant and after heat exchange in the superheater, the temperature drops to 350-420℃, and then enters the denitrification treatment facility. In this process, part of the unreacted residual ammonia in the flue gas is treated in the denitrification facility, so that the pollutant content in the flue gas is reduced. The treated flue gas returns to the waste heat boiler at a temperature of 350℃ and enters the evaporation section for further heat exchange. During the heat exchange process in the evaporation section, the water in the flue gas is evaporated, and other chemical reactions will also occur. Among them, the unreacted residual ammonia will condense on the surface of the evaporation section to form ammonium salts, and the ash will combine with other substances to form ash blocks. These ash blocks will adhere to the surface of the evaporation section. Over time, these ash blocks will gradually accumulate, causing the channel of the evaporation section to narrow and eventually become blocked, requiring shutdown and maintenance.

[0003] During the whole process, as time goes by, the energy consumption required to treat the flue gas continues to rise, resulting in a gradual increase in electricity consumption. The power consumption of the power plant is increasing day by day, while the power generation is decreasing day by day. The instability of power supply may cause the glass production line to face problems such as power outages or voltage instability, affecting the continuity of production and quality stability. In particular, in the glass production process, high environmental conditions such as temperature and humidity are required, and the instability of power supply will directly affect the control of these parameters, thereby affecting the quality and production efficiency of the glass.
