[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figures 1 and 2In an embodiment of the present invention, a multi-channel environmental protection dust removal device includes three bag dust collectors 1, the bottom inlets of the three bag dust collectors 1 are connected to an input pipe 2, the top outlets of the three bag dust collectors 1 are connected to an output pipe 3, the input ends of the three input pipes 2 are respectively connected to the No. 1 fan 4, the No. 2 fan 5 and the No. 3 fan 6, the input ends of the No. 1 fan 4, the No. 2 fan 5 and the No. 3 fan 6 are all connected to a connecting pipe 7, the input ends of the three connecting pipes 7 are all connected to a four-way pipe 8, the four-way pipe 8 has three input ends, and the three input ends of the four-way pipe 8 are respectively connected to the indoor rooms of different workshops through pipelines, the input pipe 2 and the connecting pipe 7 located in the middle position are connected to the other input pipe 2 and the connecting pipe 7 located on one side through a first pipeline connecting mechanism, and the input pipe 2 and the connecting pipe 7 located in the middle position are connected to the other input pipe 2 and the connecting pipe 7 located on the other side through a second pipeline connecting mechanism.

[0017] In this embodiment: when the device is in use, when each workshop (such as the continuous casting workshop, the refining workshop and the desulfurization and slagging workshop) is at normal working intensity, the No. 1 fan 4, the No. 2 fan 5 and the No. 3 fan 6 are started at this time. The running No. 1 fan 4, the No. 2 fan 5 and the No. 3 fan 6 generate negative pressure to suck the air from each work room in each workshop, and the dust and impurities scattered in each room enter the four-way pipe 8 along with the air, and enter the air passages of the No. 1 fan 4, the No. 2 fan 5 and the No. 3 fan 6 through the four-way pipe 8, and then enter the corresponding input pipe 2, and finally enter the bag filter 1. The impurities contained in the air are intercepted and filtered by the bag filter 1, and the filtered air is discharged from the output pipe 3;

[0018] When individual workshops are in a low-frequency labor intensity, the fans connected to the corresponding workshops (such as fan No. 1 4 on one side) are turned off, and the No. 1 pipeline connection mechanism is opened. At this time, fan No. 2 5 in the middle position is running to assist the workshop corresponding to fan No. 1 4 in dust removal, thereby turning off the fans corresponding to the low-frequency labor intensity and saving electricity.

[0019] Please refer to Figure 1 and Figure 2 The first pipeline connection mechanism includes a No. 1 connecting pipe 13 and a No. 2 connecting pipe 14. A No. 1 valve 15 is installed on the No. 1 connecting pipe 13, and a No. 2 valve 16 is installed on the No. 2 connecting pipe 14. The two ends of the No. 1 connecting pipe 13 are respectively connected to the input pipe 2 in the middle position and the other input pipe 2 at one side position. The two ends of the No. 3 connecting pipe 9 are connected to the input pipe 2 in the middle position and the other input pipe 2 at the other side position.

[0020] In this embodiment: when the workshop corresponding to the No. 3 fan 6 is at a low-frequency working intensity, the No. 3 fan 6 is turned off, and the No. 2 valve 16 and the No. 1 valve 15 are opened. At this time, the No. 2 fan 5 is running, and the negative pressure generated acts on the connecting pipe 7 connected to the No. 2 connecting pipe 14 through the No. 2 connecting pipe 14. The connecting pipe 7 sucks the air in the low-frequency working intensity workshop through the four-way pipe 8 connected thereto, and is sucked into the air duct of the No. 2 fan 5 through the No. 2 connecting pipe 14. After the air is sucked in, it is diverted through the input pipe 2 in the middle position and the No. 1 connecting pipe 13, and the air containing impurities is input into the two bag dust collectors 1, avoiding blockage caused by excessive load intensity of a single bag dust collector 1;

[0021] Similarly, when the workshop located in the middle position is in a low-frequency state, the No. 2 fan 5 is turned off, and the No. 2 valve 16 and the No. 1 valve 15 are opened, and the dust collection of the two workshops is achieved through the No. 3 fan 6.

[0022] Please refer to Figure 1 and Figure 2 The second pipeline connection mechanism includes a No. 3 connecting pipe 9 and a No. 4 connecting pipe 10. A No. 3 valve 11 is installed on the No. 3 connecting pipe 9, and a No. 4 valve 12 is installed on the No. 4 connecting pipe 10. The two ends of the No. 2 connecting pipe 14 are respectively connected to the connecting pipe 7 in the middle position and another connecting pipe 7 at one side position. The two ends of the No. 4 connecting pipe 10 are respectively connected to the connecting pipe 7 in the middle position and another connecting pipe 7 at the other side position.

[0023] In this embodiment: when the workshop corresponding to the No. 1 fan 4 is in a low-frequency working intensity, the No. 1 fan 4 is turned off, and the No. 3 valve 11 and the No. 4 valve 12 are opened. At this time, the No. 2 fan 5 is running, and the negative pressure generated acts on the connecting pipe 7 connected to the No. 1 fan 4 through the No. 4 connecting pipe 10. The connecting pipe 7 sucks in the air in the low-frequency working intensity workshop through the four-way pipe 8 connected to it, and is sucked into the airway of the No. 2 fan 5 through the No. 4 connecting pipe 10. After that, it is diverted through the input pipe 2 in the middle position and the No. 3 connecting pipe 9, and the air containing impurities is input into the two bag dust collectors 1 to avoid blockage caused by excessive load intensity of a single bag dust collector 1.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
