Energy-saving and environment-friendly process device and method for treating organic solid waste through pulsed oxygen-enriched combustion

Abstract

The invention relates to an energy-saving and environment-friendly process device and method for treating organic solid waste through pulsed oxygen-enriched combustion. The process method comprises the following steps of quantitatively pressurizing and spraying pure oxygen at certain intervals according to the shape of materials which enter a furnace and the furnace temperature condition, so thatthe materials can be fully disturbed, the heat and mass transfer process is enhanced, additionally, the materials can be fully oxidized and burnt by virtue of excessive oxygen, heat is released in theprocess of converting organic carbon into carbon dioxide and is brought out by tail gas, and the heat of the tail gas is divided into three parts to be used after passing through a heat exchanger. Compared with the prior art, the energy-saving and environment-friendly process device has the advantages that rich oxygen is indirectly provided for pulses, organic matter and oxygen are combined and are fully oxidized so as to release heat while equipment is not excessively oxidized so as not to cause the overload high temperature of a system, and the generated heat of the tail gas is fully used after heat exchange, so that gas and materials which enter a combustion furnace are heated, the combustion time of the organic matter in the furnace is shortened, and the combustion treatment efficiency of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of organic solid waste treatment, and relates to an energy-saving and environment-friendly pulse oxygen-enriched combustion process device and method for treating organic solid waste. Background technique [0002] The rapid development of industry is mainly based on the application of fossil fuels. However, fossil fuel resources are gradually being exhausted, and their excessive use has also caused environmental pollution, resulting in a decline in the quality of human life. The development of renewable energy has become the research focus of various countries. At present, water electrolysis produces hydrogen, which is used more and more due to the advantages of zero emission and zero pollution in the production process, but the reasonable and efficient use of the by-product oxygen produced in the electrolysis process has become a difficulty. The combustion of organic solid waste in environmentally friendl...

However, the service life of the combustion furnace used in this method is relatively short

[0005] Chinese patent 201810860742.X provides an environmentally friendly combustion furnace. A combustion furnace is arranged inside the combustion furnace body. A natural gas inlet is provided at the lower part of the combustion furnace body. A vent is provided at the left side of the upper part of the combustion furnace body. Pass through the combustion furnace body and extend into the combustion furnace. A blower is installed on the ventilation pipe, and a waste gas treatment device is installed in the middle section of the air induction pipe. During the combustion process of the device of the invention, the obtained solid ash still contains a large amount of organic matter, polluting the environment
