High-concentration organic waste innocent treatment system and process

Abstract

The invention provides a high-concentration organic waste innocent treatment system and process. High-concentration organic waste discharged from industrial production is mixed with coal slime or fine particle clean coal to proportionally produce coal water slurries, the water content of the coal water slurries is controlled through a slurry ability experiment, and a coal water slurry plunger pump is used to continuously and stably convey the coal water slurries to a circulating fluidized bed boiler for burning to produce superheated steam for comprehensive utilization of enterprises, so that effects of energy conservation and environmental protection are achieved. Combustion tail gases are subjected to desulfurization, denitrification and dedusting through a flue gas cleaning system and discharged until the combustion tail gases meet the requirement of environment protection, and ashes left in the production process can be used as building materials or brick-making raw materials. According to the high-concentration organic waste innocent treatment system and process, the high-concentration organic waste discharged from industrial production and coal slime or fine particle clean coal is used as raw materials of the coal water slurries, and by means of a water coal slurry clean combustion technology, the high-concentration organic waste is used as production water for the water coal slurries, so that treatment costs of high-concentration organic waste and waste water are saved, industrial production waste is absorbed, and production costs of enterprises are reduced.

Description

technical field [0001] The invention relates to a method and a device in the field of environmental protection and energy saving, in particular to a harmless treatment system and process for high-concentration organic waste. Background technique [0002] High-concentration organic waste (including waste water, waste liquid, waste residue and various sludges) mainly comes from coking, papermaking, fermentation, medicine, food and leather rubber, textile printing and dyeing, petrochemical and other industries, especially high-concentration organic waste that is difficult to biodegrade Wastes can easily cause environmental pollution and pose a threat to human health and sustainable social development. With the acceleration of the industrialization process, the discharge of high-concentration organic waste from all walks of life is still increasing. Even after certain treatment, the discharge will still cause certain harm to the environment. The typical treatment method of "red...

Problems solved by technology

Chinese Patent No. 93209804 proposes an organic waste liquid fluidized bed incinerator, which uses fluidized combustion to treat organic waste liquid, but coal is used as an auxiliary fuel, which increases the processing cost and consumes non-renewable energy

Coal slime is a low calorific value tailings with high ash content, high moisture content, fine particle size, high viscosity and poor commodity added value. The environmental problem is much bigger than washing coal gangue, and it is very easy to cause serious environmental pollution

In the market, only a part of coal slime flows into the market simply as "honeycomb coal", and most of the rest have not been developed reasonably and effectively
