Embodiment 1

[0061] see figure 1 , figure 2 as well as image 3 , This embodiment provides a dust collecting device in front of the magnesium ingot smelting reduction furnace. The dust collection device is used to collect the smoke and dust in front of the reduction furnace during the production of crude magnesium, and discharge the smoke and dust after treatment. The dust collection device includes a support 1, a smoke guide pipe 2, a track 5, a dust collection vehicle 6, a drive mechanism, a dust collection cover 7, a detection mechanism and a controller, and may also include a belt and a tension mechanism. Wherein, a plurality of reduction tanks 4 are arranged in the reduction furnace 3, and their arrangement and quantity are determined according to actual needs. The reduction furnace 3 is provided with multiple inlets and outlets, through which the reduction tank 4 can be operated, and other structures in the reduction furnace 3 can also be operated.

[0062] see Figure 4 , the ...

Embodiment 2

[0078] This embodiment provides a dust collection device in front of the magnesium ingot smelting reduction furnace, which adds a bag filter 15 and an induced draft fan 16 on the basis of the first embodiment. The bag filter 15 communicates with the smoke guide pipe 2, and it can collect the dust in the smoke from the smoke guide pipe 2. The induced draft fan 16 communicates with the bag filter 15 and absorbs the smoke and dust in the smoke guide pipe 2 through the bag filter 15 . The smoke and dust coming from the smoke guide pipe 2 will be sent into the chimney 12 and discharged after passing through the bag filter 15 and the induced draft fan 16 . In this way, the induced draft fan 16 can suck away the dust in the smoke guide pipe 2 through the bag filter 15, so that a negative pressure is generated in the smoke guide pipe 2 to ensure that the smoke in the smoke guide pipe 2 is processed in time without overflowing from the smoking window. At the same time, the bag filter ...

Embodiment 3

[0080] This embodiment provides a dust collecting device in front of the magnesium ingot smelting and reducing furnace, which is similar to the dust collecting device in front of the magnesium ingot smelting and reducing furnace in embodiment 1, the difference is that the trolley wire power supply integration 11 is added in this embodiment, At the same time, the dust collection vehicle 6 also includes a collector 66 . One end of the current collector 66 is fixed on the vehicle body 61, and the other end can follow the movement of the vehicle body 61, and the trajectory of the movement is a horizontal line. The trolley line power supply integration 11 is arranged on one side of the track 5 and overlapped with the other end of the collector 66 , and supplies power to the dust collecting vehicle 6 through the collector 66 . The cooperation mode of collector 66 and trolley line power supply integration 11 is similar to the existing trolley power supply mode, one of which is in mot...

Abstract

The invention discloses a dust collecting device and method in front of a magnesium ingot smelting reduction furnace. The device includes a bracket, a smoke guide pipe, a track, a dust collection vehicle, a drive mechanism, a dust collection cover, a detection mechanism and a controller. The smoke guide pipe is installed on the support, and is located above the reduction furnace, and a smoking window is opened on the top. The track is laid on the smoke duct. The dust collection vehicle is installed on the track, and has a smoke passage inside, and one end of the smoke passage faces the smoking window. One end of the dust collection hood faces the inlet and outlet in front of the reduction furnace, and the other end communicates with the smoke passage. The detection agency obtains the smoke and dust status information of each inlet and outlet. The controller is used to calculate the dust concentration first, then sort all the dust concentrations, and select the dust collection point, and finally drive the dust collection vehicle to move above the dust collection point, so that the dust collection hood collects the dust at the dust collection point and discharges the dust Exhausted through the smoke passage, smoking window, and smoke guide pipe. The invention can suck away the smoke and dust in time, and improves the dust collection efficiency and dust collection effect of the smoke and dust.

Description

technical field [0001] The invention relates to a dust collection device in the technical field of crude magnesium production, in particular to a dust collection device in front of a magnesium ingot smelting and reduction furnace, and also relates to a dust collection method in front of a magnesium ingot smelting and reduction furnace applied to the device. Background technique [0002] In the process of producing crude magnesium by the Pidgeon method, dolomite is used as the main raw material, and the raw material is calcined into calcined white in a rotary kiln. The main components of calcined white are calcium oxide and magnesium oxide. Using ferrosilicon as the reducing agent and fluorite as the catalyst, calcined white, ferrosilicon and fluorite powder are measured and compounded, and after grinding, they are pressed into pellets, and the pellets are put into the reduction horizontal tank, and then several reduction tanks are packed into the same reduction furnace, and ...
