Multifunctional environment-friendly auxiliary heating furnace

Abstract

The invention relates to the technical field of heating furnace accessory devices, in particular to a multifunctional environment-friendly auxiliary heating furnace. Part of heat in smoke dust can bereused, and energy is saved; the combustion efficiency of a combustion object is improved, the conversion efficiency of a chemical energy to a heat energy conversion is improved, so that the practicability is improved; meanwhile, the situation that the soot in an ash removal drawer generates dust in a combustion cavity and an ash discharge cavity is prevented, the concentration of pollutants in the smoke dust in a smoke exhaust pipe is reduced, the pollution to the environment is reduced, and the use reliability is improved; the heating furnace comprises a furnace body, the furnace body is internally provided with the combustion cavity positioned at the upper part and the ash discharge cavity positioned at the bottom, and an ash discharge drawer is arranged at the bottom of the ash discharge cavity, and the front end of the furnace body is provided with an adding port communicating with the combustion cavity; and the heating furnace further comprises an air blower, an air preheater, aconnecting vent pipe, a smoke discharging box, an air inlet, an air outlet and an ash falling hopper, a clearing port is formed in the bottom of the right end of the furnace body, the clearing port communicates with the ash discharge cavity, and a baffle is arranged at the clearing port.

[0002] As we all know, the multi-functional environment-friendly auxiliary heating furnace is a kind of equipment used in the metallurgical industry to heat materials or workpieces (usually metals) to rolling forging temperature. It is used in petroleum, chemical industry, metallurgy, machinery, heat treatment, surface It has been widely used in the fields of processing, building materials, electronics, materials, light industry, daily chemicals and pharmaceuticals; the existing multifunctional and environmentally friendly auxiliary heating furnace includes a furnace body, and the furnace body is provided with a combustion chamber at the upper part and a combustion chamber at the bottom The bottom of the ash discharge chamber is provided with an ash discharge drawer, the top of the furnace body is provided with a flue exhaust duct, the front end of the furnace body is provided with an addition port communicating with the combustion chamber, and a door panel is hinged at the addition port; now When some multi-functional environment-friendly auxiliary heating furnaces are used, fuels are added to the combustion chamber through the adding port, and the fuels are burned in the combustion chamber to convert chemical energy into heat energy, and the smoke generated is exported from the exhaust pipe, and the soot falls into the In the ash discharge drawer in the ash discharge chamber, when there is a lot of soot in the ash discharge drawer, just pull the ash discharge drawer out of the ash discharge chamber and export the soot; it is found in the use of the existing multifunctional environmental protection auxiliary heating furnace that The soot still contains a lot of heat, and if it is discharged directly, it will cause a waste of energy; and the combustion efficiency of the combustion material is low, and the chemical energy cannot be efficiently converted into heat energy, resulting in low practicability; at the same time, the soot in the ash discharge drawer It is easy to generate dust in the ash discharge chamber and combustion chamber, increase the concentration of pollutants in the smoke exhaust pipe, pollute the air environment, and lead to low reliability
