Abstract

The invention discloses a negative-pressure back-fire smelting energy-saving and environment-friendly furnace for secondary lead, and relates to the technical field of smelting furnaces. The negative-pressure back-fire smelting energy-saving and environment-friendly furnace is characterized by comprising a furnace body, an interlayer, a filter screen, a combustion tube, an exhaust tube, an exhaust fan and a waste gas treatment device, the interlayer is arranged inside the furnace body, the inside of the furnace body is divided into a lower combustion bin and an upper gas bin by the interlayer, an air hole is formed in the middle of the interlayer, the filter screen is arranged inside the air hole, the combustion tube is arranged on the upper portion of the furnace body, the inner end of the combustion tube is arranged in the gas bin, the exhaust tube is arranged on the lower portion of the furnace body, the inner end of the exhaust tube is communicated with the combustion bin and positioned on the lower side of the air hole, the exhaust fan is connected with the outer end of the exhaust tube, and the waste gas treatment device is connected with the exhaust fan through a pipeline. The negative-pressure back-fire smelting energy-saving and environment-friendly furnace is reasonable in structure, simple to operate, convenient to use, fine in environment-friendly performance and high in combustion efficiency, and energy can be saved.

Description

Technical field: [0001] The invention relates to the technical field of smelting furnaces, in particular to an energy-saving and environment-friendly furnace for negative-pressure counter-flame smelting of regenerated lead. Background technique: [0002] Lead is a silvery-white metal (compared with tin, lead is slightly light blue), very soft, and marks can be drawn on its surface with fingernails. Lead is a toxic metal, and lead is one of the important raw materials for preparing batteries. In the technology of lead recovery and utilization, the existing smelting furnaces used for lead recovery all use coal as fuel. Coal will produce a large amount of harmful gas, which is easy to pollute the environment. Moreover, the smelting furnaces that use traditional coal as fuel are in the lead A lot of heat will be wasted in recycling, which is not energy-saving enough. Invention content: [0003] The technical problem to be solved by the present invention is to provide an ener...
