Waste gas dust removal and purification device and treatment process for solid metal smelting furnace

Abstract

The invention discloses a waste gas dedusting and purifying device and treatment process for a solid metal smelting furnace. The waste gas dedusting and purifying device comprises the smelting furnace, an exhaust fan and a waste gas treatment device, the exhaust fan and the waste gas treatment device are fixedly connected through a connecting pipe, the exhaust fan is fixedly communicated with an air inlet of the waste gas treatment device, the waste gas treatment device comprises a shell, and a partition plate is fixedly connected to one side in the shell; the shell is internally divided into a cooling cavity and a processing cavity by the partition plate, the cooling cavity is filled with cooling liquid and internally provided with a coil pipe, one end of the coil pipe is fixedly connected with the exhaust fan, the other end of the coil pipe fixedly penetrates through the partition plate and extends into the processing cavity, the top of the cooling cavity is connected with a water pump through a water pipe, and the water pump is fixedly mounted on one side of the top of the shell; the end, located in the processing cavity, of the coil pipe is fixedly connected with a fixing part; a transmission assembly is rotatingly arranged in the fixing part; a rotating shaft is connected to one side of the transmission assembly; a plurality of stirring blades are fixedly connected to the upper section of the rotating shaft; and second scrapers fixedly connected to the top end of the rotating shaft are arranged at the top ends of the stirring blades, and the top ends of the second scrapers are in frictional contact with a filter plate.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification, in particular to an exhaust gas dedusting and purification device for a solid metal smelting furnace and a treatment process thereof. Background technique [0002] Non-ferrous metals are essential basic materials and important strategic materials for national economy, people's daily life, national defense industry, scientific and technological development. Agricultural modernization, industrial modernization, national defense and scientific and technological modernization are inseparable from non-ferrous metals. For example, most of the components or components required for cutting-edge weapons such as aircraft, missiles, rockets, satellites, and nuclear submarines, as well as cutting-edge technologies such as atomic energy, television, communications, radar, and electronic computers are made of light metals and rare metals in non-ferrous metals; in addition, Without nickel, cob...

Problems solved by technology

[0004] Since the exhaust gas contains a large amount of harmful substances, the purification effect of this patent on harmful substances is poor. At the same time, the exhaust gas will contain moving metal particles. This patent does not have a collection and utilization device for metal particles. Therefore, we propose a solid metal smelting furnace Use exhaust gas dust removal and purification device and its treatment process to solve the above problems
