Environmental Protection Equipment Upgraded Again to Ensure the Company’s Healthy and Green Development — A Record of Noise Reduction Retrofit for On-Furnace Dust Collection Equipment
Release Date:
20-06-29
Since smelting, pouring, and molding processes are prone to generating fumes and dust, the casting industry often gives people a dirty first impression. To thoroughly eradicate these persistent problems, dust collection during molding and pouring has been effectively addressed; however, several attempts to control fumes at the smelting station have not been very successful. After conducting a thorough investigation, the company ultimately decided to invest over RMB 1.5 million in NIDEC’s furnace-front dust collection system. By designing a dust hood that completely covers the furnace opening, the system prevents fumes from dispersing uncontrollably and captures nearly 100% of the fumes generated during smelting, achieving excellent results and completely eliminating the previous phenomenon of thick smoke billowing from the furnace opening during smelting. After implementing this dust collection equipment, the issue of smelting fume emissions has been effectively resolved. The workshop no longer carries the former smell of fumes; however, the outdoor unit of the dust collector has a significant drawback—high noise levels—resulting in “noise pollution” as a new problem. Therefore, in May of this year, the company carried out soundproofing modifications on the outdoor unit of the dust collector by erecting a soundproof wall around it and applying sound-insulating materials. Following the renovation, noise measurements at the factory boundary showed that the noise level had steadily dropped from the pre-renovation range of 58–59 decibels to below 54 decibels, meeting the standard requirement that nighttime noise at the factory boundary should not exceed 55 decibels. After the modification, people passing near the outdoor unit of the dust collector during working hours can hardly hear any noticeable noise anymore. Today, the state vigorously promotes ecological civilization construction, and environmental protection has become a top priority for enterprises. Corporate development must never come at the expense of the environment. ASIMCO Camshaft has always strived to ensure that all waste emissions, including noise, meet regulatory standards, thereby achieving safe, green, and environmentally friendly production. We will never allow environmental issues to become an obstacle to corporate development. In recent years, through continuous improvements and enhancements to our internal conditions, we have laid a solid foundation for sustainable, green development.
Due to the generation of fumes and dust during melting, pouring, and molding processes, the casting industry is often perceived as dirty. To thoroughly eliminate these persistent problems, dust collection in the molding and pouring areas has been effectively addressed; however, several attempts to control dust at the melting station have yielded only limited success. Following a comprehensive investigation, the company ultimately decided to invest over RMB 1.5 million in a NIDMAN-type pre-furnace dust-collection system. This system features a fully enclosing hood that covers the entire furnace opening, effectively preventing dust from dispersing throughout the workshop and capturing nearly 100% of the fumes generated during melting. The results have been outstanding, completely eliminating the previous phenomenon of thick, billowing smoke at the furnace opening during melting operations.
After implementing this dust-collection system, the issue of smelting fume emissions was effectively resolved; the workshop no longer carries the former acrid smell of smoke and dust. However, the outdoor unit of the dust collector has a significant drawback: high noise levels, which has given rise to a new problem—noise pollution affecting nearby residents. Consequently, in May of this year, the company undertook soundproofing modifications to the outdoor unit, erecting a sound barrier around it and applying sound-insulating materials. Following the retrofit, noise measurements at the plant boundary showed that the noise level had steadily dropped from the pre-modification range of 58–59 decibels to below 54 decibels, thereby meeting the regulatory requirement that nighttime peak noise levels at the plant boundary must not exceed 55 decibels. After the upgrade, workers passing near the outdoor unit during working hours can now hardly hear any noticeable noise.
Today, the state is vigorously promoting ecological civilization construction, and environmental protection has become the top priority for enterprises. Enterprise development must not come at the expense of the environment. ASIMCO Camshaft has always strived to ensure that all waste emissions, including noise, meet the standards, achieving safe, green, and environmentally friendly production. We will never allow environmental issues to become an obstacle to enterprise development. In recent years, through continuous improvement and optimization of our own conditions, we have laid a solid foundation for the sustainable and green development of our company.
