Embodiment 1

[0026] Dry and dehydrate the sludge to a moisture content of 20%, place it for 24 hours, and send it to a pulverizer to pulverize it into powder.

[0027] Send calcium oxide, calcium carbonate, calcium hydroxide, sodium carbonate, kaolin, sodium nitrate, and potassium permanganate into the mixer according to the ratio of 1:1:1:1:0.5:0.5:0.5 and mix evenly to obtain the ready-to-use product I .

[0028] Send the sawdust into a pulverizer and pulverize it into a powder, and mix it with the waste oil of the repair shop in a ratio of 8:3 to obtain the ready-to-use product II.

[0029] The materials to be used I, materials to be used II and powdered sludge are mixed in a ratio of 4:36:60 and sent to a mixer for uniform mixing, and then taken out and pressurized to form a formed massive sludge environmentally friendly recycled coal.

Embodiment 2

[0031] The sludge is dried and dehydrated to a moisture content of 25%, and after standing for 24 hours, it is sent into a pulverizer to be pulverized into powder.

[0032] Send calcium oxide, calcium carbonate, calcium hydroxide, sodium carbonate, kaolin, sodium nitrate, and potassium permanganate into the mixer according to the ratio of 1:1:1:1:0.5:0.5:0.5 and mix evenly to obtain the ready-to-use product I .

[0033] Put aluminum waste into a pulverizer and pulverize it into powder, and mix it with leather treatment waste oil at a ratio of 8:3 to obtain the ready-to-use product II.

[0034] The materials to be used I, materials to be used II and powdered sludge are mixed in a ratio of 3:27:70 and sent to a mixer for uniform mixing, and then taken out and pressurized to form a formed massive sludge environmentally friendly recycled coal.

Embodiment 3

[0036] The sludge is dried and dehydrated to a moisture content of 26%, and after standing for 24 hours, it is sent to a pulverizer to be pulverized into powder.

[0037] Send calcium oxide, calcium carbonate, calcium hydroxide, sodium carbonate, Guanyin soil, sodium nitrate, and potassium permanganate into the mixer according to the ratio of 1:1:1:1:0.5:0.5:0.5 and mix evenly to obtain the ready-to-use product I.

[0038] Send the solid cycloalkane into a pulverizer to pulverize it into a powder, and mix it with edible waste oil at a ratio of 10:3 to obtain the ready-to-use product II.

[0039]Mix the materials to be used I, materials to be used II, and powdered sludge in a ratio of 5:25:70 and send them into a blender to mix evenly, then take them out and press them to form, so as to obtain the molded massive sludge environmentally friendly recycled coal.

Abstract

The invention relates to a sludge environment-friendly renewable coal and a preparation method thereof. The sludge environment-friendly renewable coal adopts the following formula: 45 to 70 percent of sludge, 25 to 50 percent of combustion improver, 1 to 5 percent of ignition substance, 1 to 5 percent of oxidant, 0 to 5 percent of sulfur fixing agent and 0 to 5 percent of forming agent; and adopts the following preparation technology: 1) the sludge is dried and dehydrated and is sent into a crusher to be crushed into powder after 24 hours; 2) the sulfur fixing agent, the oxidant and the forming agent are sent into a mixing machine to be uniformly blended to obtain a mixture; 3) the combustion improver is sent into the crusher to be crushed into powder which is uniformly mixed with the ignition substance to obtain the mixture; 4) the powder sludge which is obtained in step 1), the mixture which is obtained in step 2) and the mixture which is obtained in step 3) are sent into the mixing machine to be uniformly blended to obtain a mixture, and then the mixture is taken out to be pressed and formed to obtain the formed sludge environment-friendly renewable coal. The preparation technology is simple, the raw materials can be obtained easily, the technical problem of the sludge treatment is solved through a method with the lowest cost, and a renewable energy which can satisfy the market requirement is produced.

Description

technical field [0001] The invention relates to sludge environment-friendly regenerated coal and a preparation method thereof, belonging to the technical field of renewable energy manufacturing. Background technique [0002] With the acceleration of urbanization, the rate of urban sewage treatment has increased year by year, and the sludge output of urban sewage treatment plants has also increased sharply. Sludge that has not been properly treated and disposed of enters the environment, directly causing secondary pollution to water bodies and the atmosphere, which not only reduces the effective treatment capacity of the sewage treatment system, but also poses a serious threat to the ecological environment and human activities. [0003] For a long time, affected by the trend of "heavy water and light mud" in the sewage treatment industry, the sanitary and harmless treatment and disposal of sludge have not been paid attention to and solved. In order to solve the problem of mun...
