Abstract

PURPOSE:Quick lime is mixed with waste oil to generate heat, which softens and homogenizes the oil, then, they are mixed with waste activated carbon, organic sludge and other combustible materials and cooled down to produce a fuel with high calorie and solid strength by utilizing wastes. CONSTITUTION:At first, waste oil is mixed with quick lime usually in an amount of 50-100wt% and the mixture becomes soft because its temperature rises by the heat of reaction of the quick lime with the water remaining in the waste oil and becomes homogenous. The mixture is combined with waste activated carbon, preferably of dried powder or granules, organic sludge such as waste activated sludge, combustible waste plastics, preferably liberating no harmful substances on combustion, waste timbers, rice hulls, combustible tar or pitch and cooled into a powder or solid, thus giving the objective fuel.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on a method of regenerating miscellaneous waste oil into powder or solid fuel at once, which requires a heating process, as described in Patent Application No. 075527 filed in 1982. By mixing 5 to 700% of the weight of quicklime with the waste oil, the water content reacts with the quicklime, and then an appropriate amount of coal powder is mixed, kneaded, and left to cool to produce the desired fuel. In this method, in addition to mixing coal powder, a combustible raw material similar to coal powder is mixed and used.

Coal powder/'IJ cleaning method 1. There are charcoal, organic sludge, combustible waste plastics, waste wood feathers, combustible tar, and pitch. Waste activated carbon is preferably fine powder or granular and dried, and can be used as long as it has an ash content of as little as 1+. The washable sludge and lint valley after being used for wastewater treatment can be used as wart-based sludge. Waste wood IΔ includes wood flour, bark, and edge 4.
'A It can be used in the same way as pulverized material, rice husk, etc., and these have the effect of reducing the soot generation IP by J+3 per hour of combustion. .

Waste plastic is r + l combustion (71 things are combustion (, 'l'
It can be made by grinding the material that does not discharge any real material during li powder to powder or round shape, and mixing it once.

Waste tar and pitch may also be used as long as they can be physically mixed into Pace 1 under the same conditions as waste plastic. In particular, waste wax generated from the polypropylene manufacturing process is high in calories and improves the strength of solidified fuel.

As mentioned above, by blending appropriate amounts of these materials to replace coal powder alone or in combination, the calorific value, I solidification strength, and soot reduction effect are improved compared to the case of coal powder alone, and the effect of reducing soot can be improved and disposed of. It is also effective from the point of view of the use of objects and the meaning of neck energy.

Example 1 Waste lubricant with moisture content of 75%, oil content of 70%, and ash content of 5% - Oil 10
Mix 30 parts of quicklime, 50 parts of waste propylene wax, and 50 parts of sawdust in 0 units 64. (weight), transfer it to a molding machine before the temperature drops, mold it under low pressure to about 2 kg 7 cm2, and leave it to cool. Obtain solid fuel.

This product is effective as fuel for hot water boilers in agricultural greenhouses.
