Embodiment 1

[0046] The oily sludge is industrial wastewater from refineries, electroplating wastewater, oily wastewater and domestic sewage produced by petroleum machinery processing, and activated sludge and crude oil trap bottom sludge produced after flotation, filtration, flocculation, chemical and other methods , flotation tank scum and various oily sludges of crude oil tank bottom sludge, after dehydration, recycled coal made of coal gangue waste incineration fly ash as the main raw material is used as fuel for power plants to generate electricity after combustion Waste slag, after crushing, sorting, and magnetic separation to remove waste metals, and then drying, wheel milling and sorting to make oily sludge with a particle size of -3mm and regenerated coal combustion waste slag powder for future use;

[0047] The waste slag discharged from the furnace bottom after domestic waste is incinerated for power generation is sorted, crushed, and magnetically separated to remove scrap metal,...

Embodiment 2

[0051] Get the oily sludge regenerated coal of embodiment 1 through burning waste slag powder 48kg, garbage ash powder 28kg, fly ash powder 12kg and Portland cement 15kg, particle diameter is the calcium oxide powder 12kg of-0.2mm, Calcium sulfate powder 5kg, sodium chloride antifreeze agent 0.6kg, rosin thermal polymer air-entraining agent 0.008kg, calcium sulfonate water reducer 0.2kg, sodium sulfate early strength agent 0.02kg sodium aluminate quick-setting agent 0.04kg and water 15kg, add the above raw materials into a twin-shaft mixer to make them moist, and then extrude them with mechanical vibration to form them. Under the pressure of 28Mpa, the formed oily sludge recycled coal combustion waste environmental protection bricks are produced, and then the formed oily sludge recycled coal is burned. Waste slag environmental protection bricks are sent to the autoclave for steam curing. First, the temperature is raised for 2.5 hours, then the temperature is kept at 98 degrees ...

Embodiment 3

[0053] Get the oily sludge regenerated coal of embodiment 1 through burning waste slag powder 60kg, garbage ash powder 35kg, fly ash powder 20kg and Portland cement 18kg, particle diameter is the calcium oxide powder 15kg of-0.2mm, Calcium sulfate powder 8kg, sodium chloride 0.8kg, rosin thermal polymer 0.02kg, calcium sulfonate 0.3kg, sodium sulfate 0.05kg, sodium aluminate 0.06kg and water 25kg, add the above raw materials into a twin-shaft mixer and stir to become moist Using mechanical vibration extrusion molding, under the pressure of 29Mpa, the formed light hollow block of oily sludge recycled coal combustion waste residue is manufactured, and then the formed oily sludge recycled coal combustion waste residue light hollow block is sent into the autoclave For steam curing, first heat up and heat for 2 hours, then keep the temperature at 100 degrees for 5 hours, and then naturally cool down for 2 hours to make a light hollow block product of oily sludge recycled coal combus...

Abstract

The invention relates to an environment-friendly brick produced from combustion slag of oil-bearing sludge reclaimed coal and a manufacturing method thereof. The invention is characterized in that slag powder, which is obtained by combusting reclaimed coal made of oil-bearing sludge and coal gangue powder, waste clinker powder, fly ash powder, Portland cement, calcium oxide, calcium sulfate, sodium chloride, colophony thermopolymer, calcium sulfonate, sodium sulfate, sodium aluminate, water and the like are used as raw materials. The method comprises the following steps: mixing the raw materials into a moisturized state by using a double-shaft mixer, carrying out extrusion molding in a mechanical vibration mode, steam-curing, and naturally cooling to obtain the environment-friendly brick produced from combustion slag of oil-bearing sludge reclaimed coal. The raw materials of the invention can also be used for making hollow building block, crown wall bricks, square bricks and pavement bricks with different specifications. The product has the advantages of light weight, high strength, no pollution, low cost and good benefit, and conforms to the environment protection development low-carbon economic requirements of energy saving and emission reduction.

Description

technical field [0001] The invention relates to an environmentally friendly brick produced from oily sludge regenerated coal combustion waste residue, specifically, it is a regenerated coal made of various oily sludge, dehydrated and coal gangue, waste incineration fly ash, etc. The utility model relates to an environment-friendly brick produced from burned waste slag as the main raw material, which belongs to the field of waste treatment. [0002] The invention also relates to a method for manufacturing the oily sludge regenerated coal combustion waste slag environmental protection brick. Background technique [0003] Oily sludge is industrial wastewater from oil refineries, electroplating wastewater, oily wastewater and domestic sewage produced by petroleum machinery processing. After flotation, filtration, flocculation, chemical and other methods, the activated sludge and crude oil trap bottom sludge, Combination of various oily sludges such as flotation tank scum and cr...
