Problems solved by technology

The sewage treatment industry is developing faster and faster, and the scale of development is getting bigger and bigger. The amount of sludge and garbage is increasing year by year, which not only needs to occupy a lot of land resources, but also causes secondary pollution and damage to groundwater resources. At the same time It also caused a lot of waste of resources

Embodiment 1

[0045] The sludge is the sludge discharged from the sewage treatment plant, and the plate and frame filter press or blade filter press is used to dehydrate the sludge so that the moisture content of the sludge is 40-60%.

[0046] After the garbage is sorted, magnetically separated, and scrap metal and stone impurities are removed, the waste wood, leaves, branches, and straw in the garbage are pulverized into powder with a particle size of less than 10mm.

[0047] After the garbage is sorted, magnetically separated, and scrap metal and stone impurities are removed, the waste cloth in the garbage and the leftovers of the garment factory are crushed into a powder with a particle size of less than 10mm.

[0048] After the garbage is sorted, magnetically separated, and scrap metal and stone impurities are removed, the waste film plastic in the garbage and the leftovers of the plastic factory are crushed into a powder with a particle size of 10mm.

[0049] After the garbage is sorte...

Embodiment 2

[0052] Get the sludge of the raw material 50kg water content of embodiment 1 50% sewage treatment plant, 30kg waste plant powder, 25kg part waste fabric powder, 7kg waste plastic powder, 7kg waste leather powder, 12kg calcium oxide, 4kg sulfuric acid Calcium, 0.8kg of ferrous sulfate, 7kg of magnesium sulfate, 2kg of waste engine oil and 7kg of water are mixed and stirred to form a moist state, then extruded by mechanical vibration, and made into rods of regenerated coal under a pressure of 25Mpa. After natural drying at room temperature, Made products. The product has been tested by the quality inspection department of Guangdong Province, and its calorific value is 13.86MJ / Kg, which is a qualified product.

Embodiment 3

[0054] Get the raw material 60kg water content ratio of embodiment 1 the sludge of 60% sewage treatment plant, 15kg waste plant powder, 15kg part waste fabric powder, 10kg waste plastic powder, 5kg waste leather powder, 15kg calcium oxide, 3kg sulfuric acid Calcium, 1.0kg of ferrous sulfate, 5kg of magnesium sulfate, 3kg of waste engine oil and 5kg of water are mixed and stirred to form a moist state, then extruded by mechanical vibration, and made into spherical regenerated coal under a pressure of 30Mpa. After natural drying at room temperature, Made products. The product has been tested by the quality inspection department of Guangdong Province, and its calorific value is 22.58MJ / Kg, which is a qualified product.

Abstract

The invention relates to a regenerative coal manufactured by sludge garbage and a manufacturing method; the method is characterized in that: sludge discharged from sewage treatment plants, waste plant powder, waste textile powder, waste thin film plastic powder, waste leather powder, calcium oxide, calcium sulphate, green copperas, magnesium sulfate, used oil and water are mixed and are extruded and formed by mechanical vibration, and then bar-shaped and spherical regenerative coal is manufactured at the pressure of 20-30MPa, the regenerative coal utilizes waste, and has high fuel value, and the burned lime ash can be used as raw material for producing concrete, the method utilizes waste in a cycling way, and has no pollution, low cost and good benefit, so as to solve the problem that the sludge and the garbage are difficult to treat.

Description

technical field [0001] The present invention relates to a kind of regenerated coal produced from sludge garbage, in particular it is the combustible waste wood, leaves and branches, straw, waste fabric and waste leather in the mechanically dehydrated sludge discharged from sewage treatment plants and garbage , waste plastics, etc. as the main raw materials, using chemical reactions, the recycled coal manufactured by mechanical agitation, vibration and extrusion molding belongs to the field of environmental protection technology. [0002] The present invention also relates to the manufacturing method of the recycled coal Background technique [0003] At present, the most important way to deal with the sludge and garbage discharged from the sewage treatment plant is to use the landfill method to reduce environmental pollution. With the rapid development of my country's economy and the continuous increase of urban population, the amount of garbage generated is increasing day b...
