Embodiment 1

[0061] In this embodiment, the inferior organic waste is oily acid slag, the diluted material is waste lubricating oil, the alkaline material is sodium hydroxide, and the oily acid slag is produced by Tangshan Shandao Petrochemical Co., Ltd. in the production experiment of adding acid to refine mineral oil. Yes, waste lubricating oil is replaced by car maintenance, sodium hydroxide is purchased from the market with a sodium hydroxide aqueous solution (liquid caustic soda) with a concentration of about 32%, the ambient temperature is about 25°C, and the ambient air pressure is about 100,000 Pa.

[0062] Turn on the stirring assembly of the neutralization mixer 1, respectively add 1000kg of oily acid residue and 700kg of waste lubricating oil into the neutralization mixer 1 through the injection port, and "slowly and moderately" add the mixture of oily acid residue and waste lubricating oil Sodium hydroxide aqueous solution is added, during the addition process, due to the acid-b...

Embodiment 2

[0073] The difference between embodiment 2 and embodiment 1 only lies in:

[0074] In this embodiment, the inferior organic waste is oily acid residue, the alkaline material is calcium powder, and the diluted material is organic sludge and waste emulsion.

[0075] Organic sludge is the fluid emulsified sediment produced by Tangshan Shandao Petrochemical Co., Ltd. after long-term storage of various dirty oil storage tanks. The product contains about 20% water and 10% solid phase impurities.

[0076] Waste emulsion is scrap emulsion collected from metal cutting occasions. The product contains about 35% oil, 60% water and 5% solid phase impurities.

[0077] Calcium powder is an industrial-grade calcium powder purchased from the market for neutralizing acidic substances.

[0078] The addition amount of organic sludge, emulsion and calcium powder is about 1000kg, about 500kg and about 300kg respectively.

[0079] The obtained distilled water, light distillate oil and heavy cement...

Embodiment 3

[0084] The difference between embodiment 3 and embodiment 1 only lies in:

[0085] In this embodiment, the inferior organic waste is oily acid residue and waste rubber, the alkaline material is calcium powder, and the diluted material is waste lubricating oil.

[0086] Waste rubber is the vulcanized rubber powder of scrapped automobile tires after use, and the size of the powder is about 1 mm.

[0087] Calcium powder is an industrial-grade calcium powder purchased from the market for neutralizing acidic substances.

[0088] The amount of waste rubber and calcium powder added is about 200kg and 300kg respectively.

[0089] The obtained distilled water, light distillate oil and heavy cement material are about 290kg, about 540kg and about 1320kg respectively.

[0090] Based on the change of low-quality organic waste and alkaline material, the type of diluted material and the amount of addition, the more optimized beneficial effects are:

[0091] ①Because waste rubber is added ...

Abstract

The invention relates to a pollution-free purifying and efficient using method for inferior organic wastes. The method comprises the following steps: selectively adding one of, or a combination of more than two, of an alkaline material, an acidic material and a diluted material into an inferior organic waste so as to enable the inferior organic waste to be conveniently transported and conveniently purified, and to be a apparent neutral material with a PH value ranging from 6 to 9 at the temperature of 100 DEG C, and acid waste gas produced during the reaction process is neutralized and purified by aqueous alkali and then discharged; by using a deep pressure reducing extraction technology, acidic sulfide in the apparent neutral material, which is hard to be in neutral reaction with alkaline materials, is fully released or in neutral reaction with the alkaline materials and cut into organic fuel gas, distilled water, light distillate oil and heavy cement gum material, and the organic fuel gas produced in the reaction process is led into a boiler combustor for combustion and purification, and then discharged. The method has a wide application scope, and can enable the inferior organic wastes to achieve efficient utilization on the premise of low energy consumption and zero pollution.

Description

[0001] Technical field: [0002] The invention relates to a purification and utilization technology of organic waste, in particular to a pollution-free purification and high-efficiency utilization method of low-quality organic waste. Background technique: [0003] The rapid development of science and technology has brought progress to human beings, but it has also brought crises. The environment is getting worse and worse, and energy depletion has become the focus of attention of the world. [0004] China is a signatory to the Stockholm Convention on Persistent Organic Pollutants, which came into force on November 11, 2004. Its main content is to reduce or eliminate persistent organic pollutants in order to protect human health and the environment International Action on Emissions Measures. [0005] In the document of the Hebei Provincial Committee of the Communist Party of China Jifa [2013] No. 23, "Hebei Province Air Pollution Prevention and Control Action Plan Implementa...
