Waste heat recovery device of smelting furnace

Abstract

The invention discloses a waste heat recovery device of a smelting furnace. The device comprises a furnace body, wherein a combustion chamber is arranged in an inner cavity of the furnace body; a slagoutlet and a fuel pipe are arranged on the two sides of the combustion chamber respectively, a heat preservation chamber is arranged at the top of the furnace body, the inner cavity of the heat preservation chamber is provided with a hot water tank, and the left side of the heat preservation chamber is connected to a pipeline; the bottom of the pipeline is connected to a blower, the right side ofthe blower is connected to the left side of the furnace body, a chimney is arranged in the middle of the top of the furnace body, one side of the chimney is connected to a heat conduction pipe, and one side of the heat conduction pipe is connected to a smoke discharge pipe; and the right side of the smoke discharge pipe is connected to a purifier, a filter screen is arranged in an inner cavity ofthe purifier, the top of the filter screen is provided with an activated carbon adsorption layer and the top of the purifier is connected to an induced draft fan, and a smoke outlet is formed in thetop of the induced draft fan. According to the waste heat recovery device of the smelting furnace, the heat recovery efficiency can be effectively improved through the heat conduction pipe, so that the problem that the waste heat recovery efficiency of the smelting furnace is low is effectively solved.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery, in particular to waste heat recovery equipment for smelting furnaces. Background technique [0002] Smelting is a refining technology, which refers to the extraction of metals from ores by means of roasting, smelting, electrolysis and the use of chemicals; reducing impurities contained in metals or increasing certain components in metals to produce the required metals , At present, smelting furnaces are widely used. [0003] When the smelting furnace is in use, the flue gas generated during roasting will be discharged. The heat of the flue gas is very high, and a large amount of heat is discharged into the air, causing great waste, and at the same time increasing the greenhouse effect of the atmosphere. Some current environmental protection smelting furnaces The efficiency of waste heat recovery is low, and the heat of flue gas cannot be effectively recovered and utilized. Contents...
