Technical Field
The invention relates to a fire extinguishing system, in particular to a quick fire extinguishing system of a garbage incinerator.
Background
At present, after the MFT of a garbage incinerator in a garbage incineration power plant occurs, unburned garbage on a fire grate cannot immediately exit from combustion due to higher temperature in the furnace, so that the safety of a steam-water system of a waste heat boiler is ensured, and the rapid extinction of the unburned garbage in the furnace is a necessary work for avoiding the generation of toxic pollutants such as dioxin and the like when the unburned garbage is combusted in a low-temperature environment. In addition, after the MFT of the garbage incinerator occurs, the desulfurization and denitration system synchronously exits, and when the combustion is continued in the furnace, the fuel heat is wasted, sulfides and nitrogen oxides generated by the combustion are directly discharged into the atmosphere through a chimney, so that the environment is polluted, the control pressure of a power plant on the average value of pollutant emission hours is increased, and the economical efficiency of the flue gas treatment system is reduced.
Specifically, after the MFT is triggered by the garbage incinerator in the garbage incineration power plant, the primary fan and the secondary fan are stopped completely, the in-furnace denitration and tail flue gas purification system is withdrawn, the burner blower and the auxiliary burner blower are started to keep low-frequency operation for protecting the burner, and the induced draft fan automatically runs along with the hearth pressure at low frequency. After the MFT is triggered, because the temperature in the furnace is high (more than 850 ℃), fresh air still enters the hearth through the air-smoke system, and unburned fuel can continue to burn until the unburned fuel is burned. In order to avoid burning unburned garbage to generate extremely toxic pollutants such as dioxin and the like in a low-temperature environment, and avoid discharging the unpurified flue gas into the atmosphere, the safety of a steam-water system of a waste heat boiler is ensured, and the rapid extinction of the unburned garbage in the boiler is a necessary work.

Example 1
The generator set of the garbage incineration power plant triggers the MFT of the garbage incinerator due to the failure of the water supply system, unburnt fuel continues to burn to cause the high pressure of the steam-water system, the fire-starting exhaust valve is opened to release pressure, and the working medium loss causes the water shortage of the steam drum; in order to extinguish unburned garbage in the furnace, the induced draft fan is stopped, the negative pressure in the furnace is increased, flue gas in the furnace reversely flows into the garbage pool through the garbage guide groove, the feeding work of other undetached garbage incinerators is affected, and potential safety hazards are brought. Therefore, from the aspect of safety, the quick extinction of unburned garbage in the furnace is a necessary task.

Nitrogen enters the flame root of unburned garbage on the grate 19 through the primary air chamber 18, so that the combustion part is in the nitrogen environment, and the combustion intensity is reduced until the combustion is extinguished. When the furnaceThe exhaust 19 has no visible flame and a CO (carbon monoxide) concentration of less than 100mg/m 3 And then, the nitrogen supply pipeline isolation door can be closed to stop charging nitrogen into the hearth.
After the fire extinguishing, the nitrogen environment in the hearth of the incinerator avoids the reburning and smoldering of unburning garbage, and ensures that the temperature of the fire grate 19 is not over-temperature.
