Description

technical field

[0001] The invention is applied to the field of ash removal and decoking of municipal solid waste incinerators, and particularly relates to a soot remover for municipal solid waste incinerators. Background technique

[0002] Ash accumulation and slagging on the heating surface of boilers are common phenomena in boiler operation, and they are also one of the important factors that endanger the safe operation of boilers. Since the thermal conductivity of the dust layer is hundreds of times lower than that of the metal pipe wall, even if the heating surface is slightly dusted, the additional thermal resistance brought by the dust layer will account for 1 / 3 of the total heat transfer resistance inside and outside the heating surface of the soda. above. Boiler ash accumulation and slagging problems may cause poor heat transfer on the heating surface, increase the exhaust gas temperature, and reduce boiler efficiency; in severe cases, the combustion conditions wil...

Examples

Embodiment 1

[0069] First, take 58Kg of nitrate (copper nitrate and sodium nitrate), 10Kg of borax, 10Kg of sodium chloride, 3Kg of ammonium nitrate, 4Kg of carbon powder, 3Kg of sulfur powder, 10Kg of vermiculite, and 2Kg of copper oxychloride, mix them and crush them to 50-40 mesh Fine particles account for more than 80%; then put the crushed mixture into the mixer and stir evenly; dry the stirred mixture at a drying temperature of 100°C to 150°C and a drying time of 10 to 20 minutes; finally, it is inspected and packaged Warehouse for finished products.

Embodiment 2

[0071] First, take 60Kg of nitrate (copper nitrate and sodium nitrate), 10Kg of borax, 10Kg of sodium chloride, 5Kg of ammonium nitrate, 5Kg of carbon powder, 3Kg of sulfur powder, 5Kg of vermiculite, and 2Kg of copper oxychloride, mix and crush to 50-40 mesh Fine particles account for more than 80%; then put the crushed mixture into the mixer and stir evenly; dry the stirred mixture at a drying temperature of 100°C to 150°C and a drying time of 10 to 20 minutes; finally, it is inspected and packaged Warehouse for finished products.

Embodiment 3

[0073] First, take 65Kg of nitrate (copper nitrate and sodium nitrate), 10Kg of borax, 10Kg of sodium chloride, 3Kg of ammonium nitrate, 2Kg of carbon powder, 3Kg of sulfur powder, 5Kg of vermiculite, and 2Kg of copper oxychloride, mix them and crush them to 50-40 mesh Fine particles account for more than 80%; then add the crushed mixture into the mixer-stir evenly; dry the stirred mixture at a drying temperature of 100°C to 150°C and a drying time of 10 to 20 minutes; finally, it is inspected Packaging is finished product storage.
