Abstract

The invention discloses a method of reducing smoke dust in a heat accumulating type melting furnace and relates to a method of reducing smoke dust. The invention aims to solve the problem that the effect of reducing smoke dust in the heat accumulating type melting furnace by an existing method is poor. The method comprises the following steps of: I, starting a smoke exhaust fan I and a combustionfan C when the heat accumulating type melting furnace works; II, starting a furnace top ventilating system of the heat accumulating type melting furnace to the frequency of the combustion fan C and closing a first natural gas switching valve J and a second natural gas switching valve K; III, opening a furnace door of the heat accumulating type melting furnace to dross when the temperatures of a first temperature measuring couple A and a second temperature measuring couple B are smaller than 80 DEG C simultaneously, reducing the frequency of the combustion fan C and improving the frequency of the smoke exhaust fan I, and discharging smoke dust in the heat accumulating type melting furnace through a smoke exhaust pipeline D; and IV, carrying out ignition production again after drossing. Themethod is suitable for reducing smoke dust in the heat accumulating type melting furnace.

Description

technical field

[0001] The invention relates to a method for reducing smoke. Background technique

[0002] The smoke exhaust system of the conventional regenerative melting furnace adopts the top exhaust system and the smoke exhaust hood principle when adding solvent or removing slag. This kind of smoke exhaust system has a large distance between the furnace bottom and the furnace. , When a large amount of smoke and dust is discharged, all the smoke cannot be sucked away well, resulting in a large amount of dust accumulation in the casting plant, damaging the environment and affecting the health of workers on site. Contents of the invention

[0003] The purpose of the present invention is to solve the problem of poor effect of reducing smoke in regenerative melting furnace by existing methods, and provide a method for reducing smoke in regenerative melting furnace.

[0004] A method for reducing smoke and dust in a regenerative melting furnace is accomplished in the follo...
