Waste gas and waste liquid incineration system and method

Abstract

The invention discloses a waste gas and waste liquid incineration system. The system comprises oxygen production equipment, a local oxygen increasing, combustion and mixing chamber, a primary incineration chamber, a secondary catalytic incineration chamber, an air heat exchanger and a waste heat utilization and smoke purification device which are sequentially connected; harmful waste gas or atomized waste liquid, compressed air and pure oxygen are proportionally mixed in the mixing chamber and then are fed into the primary incineration chamber for incineration. The waste gas and waste liquid incineration system has the advantages that the content of oxygen is locally improved in the primary incineration chamber for waste gas and waste liquid, the combustion speed is accelerated, the complete combustion is facilitated, the smoke exhaust amount after combustion is reduced, and the heat utilization ratio is improved; smoke after primary incineration enters the secondary catalytic incineration chamber and reacts with catalyst, toxic gases such as ammonia and hydrogen cyanide produced after primary incineration is decomposed into N2, H2 and CO2, the problem of environmental pollution caused by smoke exhaust is solved, and the energy saving and emission reduction are facilitated.

Description

[0001] technical field [0002] The invention relates to energy-saving treatment equipment for environmental protection incineration of waste gas and waste liquid, and in particular to a waste gas and waste liquid incineration system and method. Background technique [0003] my country is an emerging country with rapid development, and its resource consumption and pollutant discharge account for an increasing proportion of the world. Developing a resource-saving and environment-friendly economy will become the main direction of national economic development in the future, and low-carbon economy will become the mainstream model of my country's future economic development. [0004] In the process of industrial production in my country, a large amount of waste water, waste gas, and waste residue are produced, most of which are treated by chemical detoxification and biodegradation. Most of the treatment methods are essentially a kind of concentration technology. The concentrate...
