Waste flue gas emission equipment for aluminum smelting

Abstract

The invention discloses waste flue gas emission equipment for aluminum smelting, relates to the technical field of waste gas treatment, and provides the following scheme aiming at the problems that dust in existing waste gas is filtered by adopting a standing filter screen, meshes are easily blocked, regular replacement is needed, expenditure of enterprises is not favorably saved, and heat exchange between a heat exchange pipe and water is not efficient enough. A fixed pipe and a water storage tank are fixedly connected to the inner wall of the bottom of the box body, a mounting base is weldedto the inner wall of the fixed pipe, a filtering mechanism is movably arranged in the mounting base in a sleeving mode, a double-shaft motor is fixedly connected to the inner wall of the top of the box body, and an output shaft at the left end of the double-shaft motor is fixedly connected with the filtering mechanism; an output shaft at the right end of the double-shaft motor is fixedly connected with a first gear, and a heating mechanism is arranged in the water storage tank in a sleeved mode. The filtering ball rotates for filtering, local blockage is avoided, dust can be conveniently removed in time, meanwhile, the heat exchange pipe can be conveniently driven to rotate, and sufficient and efficient heat exchange is facilitated.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas discharge device for aluminum smelting. Background technique [0002] In aluminum smelting, a lot of waste gas is produced, which will contain a lot of dust and heat. Currently, the dust in the waste gas is usually cleaned by filter screen, and the filter screen is easy to accumulate after standing for a period of time. There is a lot of dust, which reduces the efficiency of filtration and needs to be replaced regularly, which is time-consuming and laborious, which is not conducive to saving expenses for the enterprise. Moreover, when the heat in the exhaust gas is absorbed by the heat exchange tube, the heat exchange between the heat exchange tube and the water is not sufficient, resulting in the failure of the heat exchange. The efficiency is low, so we propose a waste flue gas emission equipment for aluminum smelting. Contents of the invention [000...
