Problems solved by technology

In the current waste acid regeneration device, most of the combustion system simply uses fuel gas as the heat source, and the supplementary sulfur component required for waste acid regeneration is injected through an independent liquid sulfur spray gun. The regeneration unit is equipped with an independent sulfur raw material supply pipeline

Embodiment Construction

[0028] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0029] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0030] Such as Figure 1-Figure 2 As shown, a composite combustion system with acid gas and fuel gas spray guns includes a primary air inlet channel 7, a secondary air inlet channel 6, a number of fuel gas spray guns 3, an acid gas spray gun 4 and a swirl generator 2. The air spray guns 3 can be provided with three, four or five, depending on the requirements of the cracking furnace body 8. The primary air inlet channel 7 is vertically arranged in the secondary air inlet channel 6, and several fuels The gas spray gun 3 and the acid gas spray gun 4 are both arranged in the primary air inlet passage 7, the acid gas spray gun 4 is arranged at the central axis of the primary air ...

Abstract

The invention provides a composite combustion system with acid gas and fuel gas spray guns, which comprises a primary air inlet channel, a secondary air inlet channel, a plurality of fuel gas spray guns, an acid gas spray gun and a cyclone generator, all the spray guns are arranged in the primary air inlet channel, and the plurality of fuel gas spray guns are uniformly and annularly arranged around the acid gas spray gun; gas outlet holes are formed in the bottom end and the side wall close to the bottom end of a nozzle of each fuel gas spray gun; the gas outlet direction of the gas outlet holes in the side walls of the fuel gas spray guns is the tangential direction of a virtual circle defined by the central axes of the fuel gas spray guns, and fuel gas flow sprayed out of the gas outletholes in the side walls of the nozzles forms rotational flow rotating around the center of the virtual circle; acid gas is sprayed from the center of the rotational flow to form a mixed gas rotationalflow; the rotational direction of rotational flow formed by combustion-supporting air through a rotational flow generator is the same as that of mixed gas rotational flow. The sulfur-containing wastegas is used as an acid raw material, the raw material is saved, the acid gas and the fuel gas are uniformly mixed, and the combustion efficiency is high.

Description

Technical field [0001] The invention belongs to the technical field of combustion systems, and particularly relates to a composite combustion system with an acid gas and fuel gas spray gun. Background technique [0002] With the continuous development of industrial technology and the continuous expansion of industrial production, the problem of environmental pollution has become increasingly severe. Many companies use sulfuric acid as a production auxiliary material or catalytic promoter. The waste sulfuric acid produced by them is inconvenient to deal with. Some use acid-base neutralization treatment, and some use hoarding storage methods, which waste resources and cause environmental pollution. . [0003] The waste acid regeneration process (SAR), which uses waste acid cracking furnace to treat waste sulfuric acid and regenerates clean sulfuric acid after cracking waste acid, saves resources and protects the environment. In the spent acid regeneration process (SAR), the raw mat...
