Safe spelter smelting furnace

Abstract

The invention relates to a safe spelter smelting furnace. The safe spelter smelting furnace comprises a vertical furnace body. Multiple layers of combustion chambers are arranged in the vertical furnace body. The combustion chamber on each layer is provided with nozzles used for injecting gas or air. A plurality of smelting tanks are arranged in the combustion chamber on each layer. The openings of the smelting tanks are all formed in the outer wall of the vertical furnace body. Two flues are further arranged in the vertical furnace body and located at the two ends of each combustion chamber respectively. The two flues are communicated with the two ends of each combustion chamber respectively. A first electromagnetic valve is arranged at the communication position of each flue and each combustion chamber. Two second electromagnetic valves are arranged at smoke outlets of the two flues respectively. Pressure sensors are arranged in the two flues respectively. A main control system is arranged on the outer wall of the vertical furnace body. The two pressure sensors are connected with the main control system through lines. The main control system is connected with the two second electromagnetic valves through lines. Air pressure can be adjusted automatically, in this way, damage to the smelting furnace is avoided, the service life is prolonged, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a safe crude zinc smelting furnace. Background technique [0002] In the prior art, metal zinc smelting methods are mainly divided into wet method and pyromethod. The investment of hydrometallurgy is huge, wastewater treatment is difficult, and the selectivity to raw materials is strong; pyrometallurgy includes vertical tank smelting, blast furnace smelting and electric furnace Smelting, etc., all have the disadvantages of large investment, high production cost, low heat energy utilization rate, and high air pressure, which may easily cause safety problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crude zinc smelting furnace that can automatically adjust the air pressure, avoid damage to the smelting furnace, prolong the service life and improve safety. [0004] The technical scheme of the present invention...
