Problems solved by technology

At present, developed countries use the incineration method to deal with domestic waste, and the construction and operation costs are expensive; and when the calorific value of the incinerated waste is lower than 3.35MJ / kg, it is also required to add a combustion aid
More than 95% of domestic waste is disposed of in my country by landfill. This method causes waste of resources and can cause secondary pollution to the surrounding environment. At the same time, it occupies a large area of ​​land; in order to change the status quo, my country has also begun to use incineration technology. However, the incineration process Dioxins are produced in the environment, which is 100 times more toxic than potassium cyanide and about 900 times more toxic than arsenic. It is a highly toxic and difficult to decompose carcinogen

Embodiment 1

[0023] First, according to the material formula provided by the present invention and its weight (%) content, determine the material proportion: garbage 45.0, lignite 15.0, solvent 30.0, auxiliary agent 5, catalyst 5; weigh various raw materials by percentage:

[0024] 450kg of rubbish, 150kg of lignite from Shenyang Tiefa Mining, 300kg of anthracene oil as a solvent, 50kg of methanol as an auxiliary agent, and 50kg of catalyst hydrochloric acid.

[0025] In this method, the garbage and coal used should be pretreated first. Garbage bags are first broken, and then manually sorted to sort out the inorganic substances of waste batteries; then magnetic separation is performed to remove metal substances; then, masonry and glass substances are removed by mechanical sorting and winnowing; and then through strong crushing , so that the particle size is ≤30mm for later use; the pretreatment of lignite is through pulverization, so that the particle size reaches 200 mesh for later use; t...

Embodiment 2

[0029] According to the method provided by the invention, biodiesel is prepared. 20.0% of Shenyang Puhe sub-bituminous coal, 40.0% of household waste in Tiexi District, 30.0% of distillate oil at 340-380°C as solvent, 5.0% of cetyl alcohol as auxiliary agent, and 5.0% of catalyst industrial hydrochloric acid. Weigh each material, sub-bituminous coal 200kg, garbage 400kg, solvent 300kg, cetyl alcohol 50kg, industrial hydrochloric acid 50kg; after garbage and bituminous coal are pretreated, enter the mixer together with additives, solvents and catalysts, and after fully stirring for 11 minutes, Change over to reaction procedure, reaction temperature is 370 ℃, pressure 7.0MPa, time 60 minutes; Enter blending procedure by the ratio of 0.5%, add amyl nitrate 5kg; The technological parameter of other each procedure is all identical with embodiment 1.

Embodiment 3

[0031] Use domestic waste from residents in Quanyuan District, Dongling District, Shenyang, take Fushun oil shale, weigh materials according to the following composition formula and weight (%) ratio: garbage 35.0%, 350kg, oil shale 25.0%, 250kg, solvent 30.0%, use 340-380 ℃ distillate oil recycling, the dosage is 300kg, methanol 50kg, industrial hydrochloric acid 50kg, various materials enter the mixer, after uniform stirring for 12 minutes, transfer to the reaction process, reaction temperature 400 ℃, pressure 6.5MPa, time 50 minutes; gas oil Enter the blending process, according to the test results, add 0.8% amyl nitrate, and the weight is 8kg;

Abstract

The present invention relates to energy source technology, and is especially process of preparing diesel oil substitute with domestic garbage and coal. The present invention features that the material consists of domestic garbage 25-45 wt%, coal 15-35 wt%, solvent 30 wt%, assistant 5 wt% and catalyst 5 wt%. The coal is lignite, subbituminous coal, oil shale or turf; the solvent is anthracene oil in the initial operation stage and the 340-380 deg.c distillate oil after the equipment is in continuous operation; the assistant is methanol and the catalyst is industrial hydrochloric acid. Pre-treated garbage and coal as well as other materials are first mixed through stirring for 10-15 min, then reacted at 340-460 deg.c and 5.5-7.5 MPa for 30-70 min and finally distilled to obtain the 340 deg.c below distillate oil as the coarse diesel oil. The coarse diesel oil is blended with amyl nitrate to obtain the diesel oil substitute.

Description

technical field [0001] The invention relates to the field of energy, in particular to a new method of using urban residents' domestic garbage and low-quality coal as raw materials to replace diesel oil. Background technique [0002] With the continuous improvement of people's living standards, the amount of domestic garbage has doubled, and environmental pollution has become increasingly serious. At present, developed countries use the incineration method to deal with domestic waste, and the construction and operation costs are expensive; and when the calorific value of the incinerated waste is lower than 3.35MJ / kg, it is also required to add a combustion aid. More than 95% of domestic garbage is disposed of in landfill in my country. This method causes waste of resources and can cause secondary pollution to the surrounding environment. At the same time, it occupies a large area of ​​land; in order to change the current situation, my country has also begun to use incineratio...
