Abstract

The invention discloses oil-water coal slurry. The oil-water coal slurry is characterized by comprising the following raw materials in parts by weight: 40-60 parts of coal powder, 35-45 parts of illegal cooking oil, 8-10 parts of water and 1-12 parts of emulsifier. The invention provides a novel scheme aiming at the problems of the damage and reclamation of the illegal cooking oil. By using the method, the illegal cooking oil can be recycled to prepare the oil-water coal slurry to replace diesel to be used for igniting a water coal slurry furnace, and the illegal cooking oil is prevented from flowing back to tables.

Description

A kind of oil coal water mixture and preparation method

Technical field

The present invention relates to a kind of oil coal water mixture and preparation method, particularly a kind of oil coal water mixture for coal water slurry boiler igniting usefulness.

Background technology

Sewer oil refer in the water drain greasy floating matter or with leftovers, the oil of leftovers (common name swill) through simply processing, extracting of hotel, restaurant.A large amount of sewer oils flows back to people's dining table again after illegal retailer reclaims reworking, sewer oil is for a long time edible may cause cancer, very harmful to human body.

Summary of the invention

The objective of the invention is to, a kind of oil coal water mixture and preparation method are provided, provide a kind of new scheme of utilizing to sewer oil.

Technical scheme of the present invention.Oil coal water mixture by weight, is made up of following raw material, coal dust 40-60 part, sewer oil 35-45 part, water 8-10 part, emulsifying agent 1-2 part.

Above-mentioned oil coal water mixture by weight, is made up of following raw material, coal dust 45-55 part, sewer oil 38-42 part, water 8-10 part, emulsifying agent 1-2 part.

Above-mentioned oil coal water mixture by weight, is made up of following raw material, 50 parts of coal dusts, 40 parts of sewer oils, 9 parts in water, 1 part of emulsifying agent.

Above-mentioned oil coal water mixture, by weight percentage, described emulsifying agent is made up of following raw material, glyceryl monostearate 15-40%, polyoxyethylene sorbitan monostearate 20-60%, alkylbenzene sulfonate 3-8% and carboxymethyl cellulose 3-8%;

The preparation method of oil coal water mixture, according to said ratio, coal dust is crushed to the 300-600 order, sewer oil is added to the water stirs, add emulsifying agent simultaneously, obtain the profit mixed serum, then coal dust is joined gradually in the profit mixed serum that continues to stir, obtain oil coal water mixture after fully mixing.

Described sewer oil is earlier by filtering thick refining.

The applicant is devoted for years to the research in coal water slurry fuel, find at work, coal water slurry can replace coal to use as a kind of novel high-efficiency cleaning fuel, has burning high efficiency, load adjustment facility, reduces environmental pollution, improves working conditions and save with advantages such as coals.But coal water slurry is in use, and the point of ignition height can not directly be lighted, and fuel such as needs elder generation employing diesel oil are lighted a fire to coal water slurry, fuel such as diesel oil, and cost is higher, is unfavorable for the cost control of scale operation.The present invention is directed to harm and the recycling problem of sewer oil, a kind of new scheme is provided.Sewer oil can be utilized again, prepare a kind of oil coal water mixture, can replace the diesel oil of coal water slurry boiler igniting usefulness to use, can also avoid sewer oil to be back on the dining table.Make oil coal water mixture for sewer oil, difficult point is the complicated component of sewer oil, and vegetables oil, animal oil and a large amount of impurity are arranged, and each place, each sewer oil composition that reclaims are incomplete same.The applicant has obtained emulsifiers formula by experiment, is different from the unicity of existing oil coal water mixture emulsification, can be suitable for the sewer oil of complicated component, reaches emulsifying effectiveness preferably.The contrast of oil coal water mixture emulsification, combustion experiment effect sees Table one:

Table one: emulsification experiment

As shown in Table 1, the mentioned emulsifier prescription, the second assembly side wherein: sucrose fatty ester 15-35%, polyoxyethylenesorbitan sorbitan monooleate 30-60%, sulfonated lignin 3-15% and xanthan gum 3-10%, the oil coal water mixture of preparation, storage period is long, burning is good, and effect is best, and the effect of the first assembly side is taken second place.But totally all sewer oil being prepared oil coal water mixture has certain effect.Technical scheme of the present invention, can administer the illegal act with " sewer oil " processing and eating oil from the source, avoid kitchen castoff is directly entered food chain as feed, can solve effectively also that kitchen castoff directly enters water drain or receive by domestic waste that the fortune treatment system is carried out landfill or burning causes the wasting of resources and problem of environmental pollution.Can promote the kitchen castoff recycling, turn waste into wealth, turn harm into good, be not only the important content of developing a circular economy, also be the fundamental measure that solves the food-safety problem of kitchen castoff initiation.
