Lead acid battery manufacturing can generate fine lead-containing particulate matter during plate processing, assembly, and other production operations. Effective dust collection requires suitable source capture, industrial filtration equipment, filter media, and final filtration selected according to the actual process conditions.

Jiangsu Erhuan Environmental Technology Co., Ltd. supplied customized dust collection equipment for Shandong Chaowei, a subsidiary of Chaowei Group, for lead dust and particulate control in battery manufacturing.

Battery Manufacturing Dust Collection Case Study

According to the original project record, Jiangsu Erhuan has supplied environmental protection and dust collection equipment to Chaowei Group for many years, with cumulative purchases reaching approximately RMB 120 million.

The dust collection equipment was used for processes involving lead-containing dust and particulate matter generated during lead acid battery manufacturing.

Why Is Lead Dust Collection Important in Battery Manufacturing?

Lead-containing dust can be generated during battery plate production, material handling, assembly, and related manufacturing processes. Because these particles can be very fine, the filtration system must be selected according to particle characteristics, required airflow, dust concentration, process conditions, and required filtration performance.

A properly configured industrial dust collection system helps capture particulate matter near the source and prevent unnecessary dispersion through the production area.

Why Use a Vertical Cartridge Dust Collector?

A vertical cartridge dust collector uses pleated filter cartridges to provide a large filtration area within a relatively compact equipment structure.

For fine and dry industrial dust, cartridge filtration can provide effective primary dust collection when the filter media, filtration area, airflow, and cleaning system are correctly selected for the application.

Vertical cartridge installation can also help accumulated dust release from the filter surface during pulse-jet cleaning, depending on the collector design and operating conditions.

What Is the Role of HEPA Filtration?

For applications requiring higher final filtration performance, a secondary HEPA filtration stage can be added after the primary dust collection stage. HEPA filtration is used to capture very fine particulate matter remaining in the airflow after upstream filtration.

The required final filtration level should be determined according to the process, applicable requirements, and intended air discharge or recirculation conditions.

Can a Dust Collector Achieve Very Low Lead Emissions?

According to the original Chaowei project record, the filtration system was designed for lead and lead-compound emission concentrations below 0.1 mg/m³ under the specified project conditions.

Actual outlet concentration depends on the complete system configuration, inlet dust concentration, filter condition, operating parameters, maintenance, sampling method, and applicable test conditions. Therefore, a specific emission value should be evaluated and confirmed for each project rather than treated as a universal performance value for every dust collector.

What Information Is Needed for a Battery Dust Collector?

Important information includes required airflow, battery manufacturing process, dust composition, particle characteristics, dust concentration, operating temperature, moisture or oil content, installation conditions, electrical supply, required filtration level, and applicable safety requirements.

Production equipment drawings, capture hood information, photographs, and duct conditions can also help clarify the dust collector requirements.

Cartridge Filtration and HEPA Filtration: Why Use Multiple Stages?

Primary cartridge filtration and secondary high efficiency filtration perform different functions. The cartridge dust collector handles the main dust loading and uses pulse-jet cleaning for continued operation, while the downstream high efficiency filter can provide an additional filtration stage for finer residual particulate matter.

This multi-stage approach can be considered when the application requires higher final filtration performance than primary cartridge filtration alone.
