Embodiment 1
[0029] A method for manufacturing sludge biomass environment-friendly fuel mainly consists of the following steps:
[0030] 1) Sludge pretreatment: Transport the wet sludge with a moisture content of 82% to the pretreatment tank, add water to dilute, mix evenly, add deodorant to remove odor, and then add fungicide to kill pollution microorganisms, pests and pathogens in mud;
[0031] 2) Sludge modification: transport the pretreated sludge to the reaction tank, keep stirring continuously, and add modifiers, sulfur fixers, and heavy metal stabilizers according to the amount, and the time for adding each agent The interval is about 10 minutes. After all the chemicals are added, stir continuously for 1 hour before adding the crushed sawdust. The dosage of sawdust is 40% of the weight of the sludge;
[0032] 3) Deep dehydration of sludge: Use a screw pump to transport the sludge into the filter press for deep dehydration. After deep dehydration, the moisture content of the sludge ...
Embodiment 2
[0036] A method for manufacturing sludge biomass environment-friendly fuel mainly consists of the following steps:
[0037] 1) Sludge pretreatment: Pipeline the sludge with a moisture content of 98% to the pretreatment tank, add deodorant to remove odor, and then add bactericide to kill microorganisms, pests and pathogens in the sludge.
[0038] 2) Sludge modification: transport the pretreated sludge to the reaction tank, keep stirring continuously, and add modifiers, sulfur fixers, and heavy metal stabilizers according to the amount, and the time for adding each agent The interval is about 10 minutes. After all the chemicals are added, stir continuously for 1 hour before adding the crushed shavings, the amount of shavings added is 40% of the weight of the sludge;
[0039] 3) Deep dehydration of sludge: Use a screw pump to transport the sludge into a filter press for deep dehydration. After deep dehydration, the moisture content of the sludge is reduced to below 20%. After t...

[0043] A method for manufacturing sludge biomass environment-friendly fuel mainly consists of the following steps:
[0044] 1) Sludge pretreatment: Pipeline the sludge with a moisture content of 93% to the pretreatment tank, add deodorant to remove odor, and then add bactericide to kill microorganisms, pests and pathogens in the sludge.
[0045] 2) Sludge modification: transport the pretreated sludge to the reaction tank, keep stirring continuously, and add modifiers, sulfur fixers, and heavy metal stabilizers according to the amount, and the time for adding each agent The interval is about 10 minutes. After all the chemicals are added, stir continuously for 1 hour before adding the crushed dead branches and leaves. The dosage of dead branches and leaves is 20% of the weight of the sludge;
[0046] 3) Deep dehydration of sludge: Use a screw pump to transport the sludge into a filter press for deep dehydration. After deep dehydration, the moisture content of the sludge is redu...
