Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing:

[0026] Such as figure 1 , figure 2 As shown, a high-efficiency thermal oxidation furnace with low supplemental combustion flue gas constant velocity staged reaction, the thermal oxidation furnace includes a furnace body and a burner 1, and the burner 1 is arranged at the front end of the furnace body. The burner 1 has an independent combustion-supporting air inlet 1.1; the furnace body includes a combustion section 2 that uses high-calorific-value fuel and combustion-supporting air to generate high-temperature flue gas through peroxygen mixed combustion, and a combustion section for gradually thermally oxidizing and decomposing the exhaust gas. Multi-stage thermal oxidation section; in this embodiment, the thermal oxidation section is three-stage, that is, the primary thermal oxidation section 6, the secondary thermal oxidation section 10 and the third-stage thermal oxida...

Abstract

The invention relates to a technology of waste thermal oxygenolysis, and in particular relates to an efficient thermal oxidation furnace for low afterburning-amount smoke constant-speed grading reaction. The thermal oxygenolysis furnace comprises a furnace body and a combustor (1); the combustor (1) arranged at the front end of the furnace body is provided with a combustion-supporting air inlet (1.1); the furnace body comprises a combustion section (2) and multiple stages of thermal oxygenolysis sections; the combustion section (2) is provided with a waste gas inlet (2.1); each of the multiple stages of thermal oxygenolysis sections is provided with a waste gas inlet, a first-stage air inlet and a second-stage air inlet; the waste gas inlet of each stage of thermal oxygenolysis section is positioned between the first-stage air inlet and the second-stage air inlet; the waste gas from the combustion section and the multiple stages of thermal oxygenolysis sections and air enter the furnace body at an included angle of 20-60 degrees relative to the axle of the furnace body; and the flow rates of smoke in the combustion section and the multiple stages of thermal oxygenolysis sections are equal. The furnace has the characteristics of strong combustion stability, low mixing amount of high-grade fuel, simple and reliable structure, stable and complete oxygenolysis, high efficiency and low cost, and is convenient to operate.

Description

technical field [0001] The invention relates to thermal oxidation decomposition technology of waste, in particular to a high-efficiency thermal oxidation furnace with low supplementary combustion amount flue gas constant velocity graded reaction, which is used in petroleum refining, chemical production, coal deep processing industry, and high-efficiency thermal oxidation decomposition of waste gas. Background technique [0002] The ultra-low calorific value waste gas produced in the industrial production process of petroleum refining, chemical production, and coal deep processing industry contains toxic and harmful components. Direct discharge, not only waste energy but also pollute the environment. In order to achieve safe emission reduction of air pollution. Thermal oxidation of exhaust gases is required. Decompose the toxic and harmful components in the exhaust gas into low-toxic or non-toxic components. The hot flue gas produced by the reaction can be used for waste h...
