초미세먼지 흡입해 고체 덩어리로 뱉어낸다_산업뉴스 [산업방송 채널i]

[Report] A street sweeper driving on a road covered in sand and dust. This is a hydrogen-powered road sweeper jointly developed by Geumcheon-gu and YJ Industry, a company specializing in street sweepers. Rotating brushes at the bottom of the vehicle sweep up trash and dust, while a suction device draws in even airborne dust. It can reduce dust scattering on the road without the need to spray water like conventional street sweepers. After the vehicle passes, a clean road free of trash and dust is revealed. In particular, this vehicle collects inhaled debris in three stages: trash, fine dust, and ultrafine dust. The amount collected by type can also be checked in real-time. [Hwang Jun-pil – Officer, Cleaning Administration Division, Geumcheon-gu] It possesses outstanding cleaning performance capable of sucking up up to 99% of fine dust and ultrafine dust, far exceeding the Ministry of Environment's certification standard of 95%. Existing road sweepers were managed simply based on mileage, making it difficult to verify their actual cleaning effectiveness. To address these issues, a smart system has been introduced that automatically sorts waste, fine dust, and ultrafine dust, and measures the amount collected in real time. Another key feature is that, as a hydrogen vehicle, it emits no exhaust fumes. Noise levels are also more than 9 decibels lower than those of diesel vehicles, making it suitable for nighttime operation in residential areas. [Reporter Kim So-yeon] The vehicle has been deployed near Siheung-daero in Geumcheon-gu and has begun actual operation. The discharge process, which was previously performed manually by workers after collection, is now carried out automatically simply by connecting a hose. The collected dust passes through a solidification device and is discharged in the form of fist-sized pellets. This method can solidify approximately 21 kg of fine dust per hour. In particular, it can reduce both the problem of re-suspension of fine dust during the discharge process and worker safety issues. [Hwang Jun-pil – Officer, Cleaning Administration Division, Geumcheon-gu] We can measure real-time road pollution levels through dust data collected during operation. Furthermore, regarding the solidification device, we have eliminated risk factors such as respiratory diseases for workers by utilizing a machine instead of manual processing. Additionally, since this technology is patented, we expect it to contribute to the district's finances if it is expanded to other municipalities. Geumcheon-gu anticipates that this solidification technology will also help improve the urban environment, as it can be applied to existing garbage trucks.
