Heat-storage lead-melting furnace

Abstract

The invention discloses a heat-storage lead-melting furnace ,which comprises a pot body, a furnace body and two heat-storage combustion components, wherein the pot body is arranged on the furnace body which is internally divided into two independent heating cavities by a partition; each heating cavity is communicated with one heat-storage combustion component by a flue gas pipeline arranged on the furnace body; the heat-storage combustion components are arranged at the outer side of the furnace body; each heat-storage combustion component comprises a combustion section used for generating high-temperature gas for heating, and a heat-storage section used for providing high-temperature air for the combustion section; and the combustion sections are communicated with the heating cavities by the flue gas pipeline. The heat-storage lead-melting furnace has the advantages of simple and compact structure, small volume, convenient installation and maintenance, good heating effect, long service life and the like.

Description

technical field [0001] The invention mainly relates to the field of metal melting and refining equipment, in particular to a metal lead melting equipment. Background technique [0002] At present, non-ferrous enterprises have been using chamber combustion indirect heating to melt and refine lead. The furnace body is composed of a combustion chamber and a heating section. The combustion chamber produces high-temperature flue gas of about 1100 ° C and enters the heating section of the furnace body to directly heat the lead melting pot, gradually melting the lead block in the pot and performing refining treatment. After heating, the flue gas temperature is still as high as 1000°C. After simple treatment, it is directly evacuated, so the thermal efficiency of this furnace type is very low. Due to the frequent fluctuations of the flue gas in the lead melting and refining process, the fluctuating range is huge, and the high-temperature waste heat recovery method of metal heat exc...

Problems solved by technology

The length of the flame is determined by the ratio of gas to air and the mixing effect. When the flame is long, it may directly contact the heated pot body, causing local high temperature overheating and burning of the pot body; moreover, the regenerator uses heat storage balls as the heat exchange medium , the heat exchange specific surface area is small, the required volume is too large, the equipment volume is too large, and the equipment foundation of the regenerator is lower than the furnace body foundation, which increases the cost of the foundation; at the same time, the resistance of air and flue gas passage is relatively large, requiring The power provided is also large, resulting in high wind pressure and high energy consumption of the blower and induced draft fan
