Embodiment Construction

[0040] Implementation example one:

[0041] Take 30kg of soda ash, 30kg of zinc oxide, 20kg of sodium nitrate, 10kg of borax, 5kg of sodium chloride, 3kg of vermiculite, and 2kg of copper oxychloride, mix them and crush them until the particles with a fineness of 50-40 meshes account for more than 80%; Put the mixture into the mixer and stir evenly; dry the evenly stirred mixture at a drying temperature of 150°C and a drying time of 20 minutes; finally, it is inspected and packaged as a finished product for storage. Using the decoking and dust-removing agent of this implementation example can greatly alleviate the coking and ash deposition on the heating surfaces of the municipal solid waste incinerator, prolong the safe operation period of the incinerator, reduce the exhaust gas temperature by 5-15°C, and increase the thermal efficiency by about 1 %.

[0042] Implementation example two:

[0043] Take 25kg of soda ash, 28kg of zinc oxide, 25kg of copper nitrate, 7kg of borax...

Abstract

The invention relates to a decoking and ash removing technology for an urban domestic garbage incinerator, and discloses a decoking and ash removing agent for the urban domestic garbage incinerator and a preparation method thereof. The invention is suitable for the formula of the decoking and ash removing agent with calcium-aluminum silicate as a main component for slag formation and ash accumulation. The mass percent of the components of the decoking and ash removing agent is as follows: soda ash: 25 to 30%; zinc oxide: 25 to 30%; sodium nitrate or potassium nitrate: 20 to 25%; borax: 5 to 10%; sodium chloride: 5 to 10%; vermiculite: 1 to 4%; and copper oxychloride: 1 to 4%.

Description

technical field [0001] The invention relates to a decoking and ash removal technology for municipal solid waste incinerators, in particular to a decoking and dust removal agent for municipal solid waste incinerators and a preparation method thereof, which is suitable for slagging with calcium aluminum silicate It is a coke and dust removal agent formula with the main components of ash accumulation. Background technique [0002] With the continuous acceleration of China's urbanization process, the amount of municipal solid waste is increasing, and its growth rate is also increasing. With the improvement of residents' living standards, the content of organic matter in municipal solid waste continues to increase, and the corresponding calorific value of waste also increases. [0003] Waste incineration power generation technology has become a kind of urban waste disposal and resource recovery in developed countries because it can realize the maximum volume reduction, harmless ...
