Description

Combustible waste gas burning warming furnace

Technical Field

The invention belongs to energy-saving equipment, and particularly relates to a combustible waste gas combustion heating furnace.

Background

The waste gas incinerator is one equipment utilizing the heat produced by burning auxiliary fuel to raise the temperature of inflammable harmful gas to reaction temperature for oxidation and decomposition. The waste gas incinerator is suitable for treating waste gas of spraying and drying equipment and purifying harmful gas emitted from petrochemical, medicine and other industries. The method has the advantages of purifying the gas containing water-soluble or viscous substances and high molecular substances in the organic waste gas. The requirements of environmental protection and labor protection are met, and meanwhile, heat exchange equipment is added, so that the purposes of waste heat recycling and energy saving are achieved.

However, the current incinerator is generally expensive in cost and cannot be accepted by many small and medium-sized enterprises.

In addition, the waste gas incinerator is an effective device for preventing organic solvent from volatilizing into the atmosphere to cause environmental pollution. If the waste gas is collected and sent to a waste gas incinerator for incineration in the production process, the organic solvent is oxidized and decomposed into H2O and CO2 and then discharged, and therefore the environment is not polluted. The problem of environmental protection has been receiving more and more attention from people in all communities. Therefore, most plants are also equipped with waste gas incinerators to treat the organic waste gas generated during the production process. The conditions for complete oxidative decomposition of organic substances (including benzene-ring-containing compounds such as phenol) are such that the oxidation temperature is 760 ℃ or higher. Therefore, in order to make the exhaust gas discharged after the combustion of the exhaust gas fed into the exhaust gas incineration furnace not pollute the environment, the combustion temperature of the exhaust gas incineration furnace must reach 760 ℃. The higher the temperature of the incinerator furnace, the more fuel is consumed. Some plants use low-temperature combustion, i.e. furnace temperatures below 760 ℃ (e.g. 700 ℃, even below 600 ℃) in order to save fuel and reduce production costs. So that the organic solvent or other harmful components (such as phenol, formaldehyde and the like) can not be completely oxidized and decomposed. The harmful components can be detected to exceed the national standard on the exhaust chimney of the incinerator. Within several hundred meters from the incinerator, the odor and falling matter of the above organic substances can be smelled. Therefore, it is ensured that the exhaust gases generated in the production of the above-mentioned products do not pollute the environment: (1) establishing a waste gas incinerator or other organic matter recovery and treatment device; (2) the burning temperature of the hearth of the waste gas incinerator must reach over 760 ℃.
