CUSTOMER PROFILE: DSK-1 Rostokinskiy ZHBI, Construction materials (Moscow, Russia)
PROBLEM: High indoor concentration of welding fumes
Customer had a problem with emissions of hazardous welding fumes and metal dust during the mold restoration. Broken molds have to be welded and then grinded to get rid of scales and barrs. Customer has 4 mobile and 1 stationary welding post and six grinding posts all of them without any ventilation solutions to capture the emissions from these processes. A high concentration of dust and fumes were constantly present in the premises. These bad working conditions affected the quality of the products and made a serious threat to health of the workers.
SOLUTION: Wall-hanging filter units
To solve the customer’s problem SovPlym offered a range of flexible and reliable solutions. I order to save space in the premises, the mobile welding posts were equipped with wall-hanging filters with flexible extraction arms. For fumes extraction from stationary welding post SovPlym offered efficient ESP filter, that allows to capture the smallest of the hazardous aerosol particles. To capture the dust generated by grinding process, one the most reliable and proven solution was used – PU dust collector units. By installation of the filter units, dust collectors and extraction arms, SovPlym ensured “at source” capture of virtually all the emissions and reduced the concentration of hazardous dusts and fumes to safe levels.
TECHNICAL DESCRIPTION: Installation and system details
To provide effective extraction of welding fumes from non-stationary welding posts, the DCSC-W filter units with EF extraction arms were installed. Extended design of EF arm allowed to increase the service area for molds and to repair them faster. Stationary welding post was equipped with ESP filter combined with BEA extraction arm. Installation of wall hanging filter units allowed to keep the workspace free and to fit the equipment into limited space. To capture the dust from grinding process a specialized PU dust collector units were used with custom-made connections to standard suction casings of grinding machines.
