The invention discloses a high-efficiency environment-friendly dust removal device. The device includes a device body, the top of the left side of the device body is communicated with a first passing pipe, the right side of the device body is fixedly connected with a dust storage box, the top of the device body is provided with a blower, the outlet of the blower is communicated with a dust outlet pipe, the end, away from the outlet of the blower, of the dust outlet pipe is communicated with the top of the dust storage box, the inlet of the blower is communicated with a dust inlet pipe, and the end, away from the inlet of the blower, of the dust inlet pipe penetrates through the device body, extends into the device body and is communicated with a communication pipe. According to the high-efficiency environment-friendly dust removal device, through the arrangement of the blower, dust in the device body can be sucked into the dust storage box through the dust inlet pipe and the dust outlet pipe, and the dust can be collected and treated; through the arrangement of the communication pipe and the arrangement of a dust suction pipe, the area of dust absorption is increased, the cleaning efficiency is improved, and at the same time, the problems are solved that the dust cannot be cleaned thoroughly, it is difficult to collect treated dust because the treated dust is directly discharged into air, and then the treated dust causes pollution to the environment and is harmful to human-body health.
