Problems solved by technology

[0005] 2. The volume ratio of CO is about 0.1-5%. For the case of fuel gas, CO is most likely to come from the incomplete combustion of CH4;
However, this method not only brings many restrictions to site design and construction, but also requires high processing and installation costs.

Abstract

The invention discloses an industrial combustion furnace for treating exhaust gas and waste liquid and a treatment method. The combustion furnace comprises a furnace body, and the furnace body sequentially comprises a feeding area, a mixing area, a main combustion area and a rear combustion area; a center air gun, an air inlet pipeline and a waste pipeline are arranged in the feeding area; the air enters the mixing area from the center air gun and the air inlet pipeline and sequentially flows through an outer air cavity, an air deflector and a first swirling device; the exhaust gas and the waste liquid enter the mixing area from the waste pipeline and sequentially flow through a waste gun and a second swirling device; the waste gun is arranged on the outer side of the center air gun in a sleeving mode, and the waste gun and the center air gun are uniform in extension direction and are communicated with the mixing area. The method comprises the steps that a, the air enters the mixing area from the center air gun and the air inlet pipeline; b, fuel gas enters the main combustion area and is mixed with the air for combustion; c, the exhaust gas and the waste liquid enter the mixing area from the waste pipeline; d, the mixtures of the air, the exhaust gas and the waste liquid enter the main combustion area and are ignited; e, the exhaust gas and the waste liquid enter the rear combustion area after being ignited. According to the invention, the reaction area of the exhaust gas and the waste liquid and the reaction area of the oxygen are separated, the combustion time of the exhaust gas and the waste liquid and the combustion time of the oxygen are separated, the combustion efficiency is improved, and pollutant residues in tail gas are reduced.

Description

technical field [0001] The invention relates to the field of waste gas and waste liquid treatment, in particular to an industrial combustion furnace and a treatment method suitable for treating waste gas and waste liquid. Background technique [0002] At present, the mainstream waste gas and waste liquid treatment technology at home and abroad is mainly based on high-temperature incineration, and the residual organic matter in the waste gas and waste liquid, H 2 S, NH 3 and other harmful substances are oxidized to CO 2 , H 2 O, SO 2 , NO 2 etc., and then go through desulfurization, reduction, alkali washing and other processes, and discharge after meeting the national environmental protection requirements. High-temperature incineration is the key process flow, and the main equipment for realizing this process is various forms of industrial combustion furnaces. [0003] to handle H2 S Taking the gas sulfur recovery combustion furnace as an example, the gas analysis at ...
