Description
Technical Field
The utility model relates to a waste incinerator waste heat collection device belongs to waste heat recovery device.
Background
In recent years, under the increasingly severe situation of the 'waste surrounding city', waste incineration power generation is one of the best ways for disposing domestic waste in a 'reduction, harmlessness and recycling' manner.
When a large amount of household garbage is accumulated in the garbage storage pit and is to be incinerated, part of liquid carried by the garbage or waste liquid generated after the garbage is decayed gradually leaks to the bottom of the garbage storage pit. The landfill leachate contains a large amount of bacteria, pollutants and the like, and if the landfill leachate is not treated, soil is easily polluted, and even underground water can be influenced.
It is one of the best processing mode to collect back through incineration disposal with landfill leachate, and the incineration efficiency can effectively be improved through preheating the back and spouting into the burning furnace through atomizer before the landfill leachate incineration disposal, reduces the injury of low temperature liquid to burning furnace, if heat the then cost is higher to landfill leachate alone, the energy waste is serious.
