Burner for rectisol incinerator

Abstract

The invention discloses a burner for a rectisol incinerator, and belongs to the field of burners. The technical problem to be solved is to provide the burner for the rectisol incinerator that the structure is simple, the control of fuel gas and other gas gases is independent, mixing is carried out after the gas enters the burner, potential safety hazards can be eliminated, gas does not cross, andthe safety coefficient is high. According to the technical scheme adopted for solving the technical problem, the burner for the rectisol incinerator comprises a furnace barrel, wherein a secondary fuel gas inlet pipe is arranged at the front part of the furnace barrel, a primary nozzle is arranged at the rear part of the furnace barrel, other gas inlet pipes are arranged between the primary nozzleand the secondary fuel gas inlet pipe, the outlet of the secondary fuel gas inlet pipe is divided into a plurality of nozzles which are annularly arranged, an annular wind shield is arranged at the outlet of each nozzle, and each annular wind shield is a conical wind shield. The burner for the rectisol incinerator can be widely applied to the field of burners.

Description

technical field [0001] The invention relates to a burner for a low-temperature methanol washing incinerator, belonging to the technical field of burners. Background technique [0002] The low-temperature methanol scrubbing tail gas incinerator is an important equipment in the commonly used waste gas treatment system, and the burner is the key component of the incinerator. The structure of the burner determines the key indicators such as the gas mixing degree, fluid velocity and flame stability in the incinerator. The burner is at the front end of the incinerator, and its function is to make the exhaust gas and air mix well and provide a stable flame for complete combustion, so the burner plays an important role in maintaining the normal operation of the incinerator. [0003] The existing burner structure is relatively simple, the controllability of the combustion air flow is poor, and it cannot be used in various furnace types and various working conditions. The main problem...

AI Technical Summary

Problems solved by technology

[0003] The existing burner structure is relatively simple, the controllability of the combustion air flow is poor, and it cannot be used in various furnace types and various working conditions. The main problems are as follows: 1. The secondary combustion gas and exhaust gas cannot be independently controlled inside the burner; 2. The combustion-supporting air swirler of the burner is an external rotation structure. After the secondary combustion gas is mixed with the exhaust gas and enters the incinerator, heat cannot be released immediately to make the exhaust gas reach the oxidation temperature, which causes the high-temperature section of the incinerator to move backward, increasing the incinerator. 3. When the combustion gas enters the exhaust gas, it needs to be purged with nitrogen to prevent the gas from passing through, and to prevent the pipes in the incinerator from returning to high temperature, which increases the difficulty of use; 4. The combustion-supporting air and fuel gas are pre-prepared before entering the burner Mixed, there is a risk of flashback when burning
