Two-stage incineration process
Hits:462  Addtime;2019-7-18 [Print]  [Back]

          The waste in the fixed grate incinerator is heated and incinerated by the burner, so that the organic matter in the material is completely decomposed. However, the gas generated from the manual decomposition is introduced into the secondary combustion chamber and burned again at a high temperature.The combustion chamber and the second combustion chamber are equipped with oxygen supplementary air inlet with different angles and sufficient volume to rotate the combustible gas and ensure the flue gas residence time. The central temperature of the combustion furnace reaches 1150℃, and the flue gas residence time is no less than 2 seconds.

1. wide adaptability to waste, and can deal with waste liquid and waste gas.
2. intermittent feeding or continuous feeding, simple operation, zero contact between personnel and garbage, and greatly reduce the labor intensity of operation.
3, dioxins tend to zero emissions, emissions of non-toxic and tasteless gas, no black smoke, odor, in line with the national environmental requirements.
4. Compact equipment, minimal waste gasification, incineration and dust generation during static pyrolysis, greatly reducing the purification load of follow-up exhaust gas and effectively avoiding heavy metal fly ash pollution.
5. Make full use of the pyrolysis energy of waste to reach the temperature of secondary combustion, thus greatly reducing energy consumption.
6. negative pressure design, high degree of automation, automatic adjustment of air, maintain the normal stability of the furnace.The flue gas temperature at the outlet of the second combustion chamber automatically adjusts the burner's state to reach the automatic start and stop process.
7. When the calorific value of waste is 2500-3000 kcal, no additional fuel is needed for combustion, and the central temperature of the secondary chamber is up to 1,150 ℃.
8. The material can be discharged automatically or manually according to user requirements.      


          Chemical production in the process of high concentration organic wastewater containing salt COD BOD5 concentration is higher in refractory containing harmful pollutants, great damage to human survival environment, these not only in the wastewater containing refractory organic compounds containing poisonous harmful pollutants, the contains of salts and corrosive acid radical ion in environmental treatment more difficult, to complete processing refractory organic industrial wastewater containing play green harmful pollutants to achieve environmental protection standards emissions, zero pollution, protect human survival of the earth's environment, must take the scientific method.

        The disposal of salt in high concentration organic waste liquor after incineration
        The salt generated from the incineration is recycled in solid form to realize resource utilization.Salt from the bottom of the furnace into the cooling conveyor, cooling into the scraper conveyor recycling packaging, this part accounts for about 60-70%, a small amount of ash through the flue in the exhaust gas treatment equipment dust bucket concentration, recycling amount is about 20-30%.The rest ash is collected by the cloth bag dust collector, which accounts for about 10% of the total salt in the scraper conveyor of the dust collector. The unified collection is realized, and the dust is very few and the working environment is good.
