Abstract

The invention discloses a nitrogen closed suction type pneumatic conveying system for lead powder. The system comprises a lead powder storage bin (1), a lead powder discharging device (3) arranged below the lead powder storage bin (1), a lead powder transmitter (4), a delivery pipeline (5), a gas-solid separating device (6), an ultrafiltration device (7), a lead powder bin (8), a nitrogen return pipeline (9), a vacuum pump device (11), a nitrogen storage tank (13), a system control device (15) and the like which are sequentially connected; a level gage (2) is arranged in the lead powder storage bin (1); a pressure sensor (10) is arranged on the nitrogen return pipeline (9); a nitrogen generating device (12) is arranged on a nitrogen closed cycle system; the nitrogen storage tank (13) is provided with a nitrogen concentration detector (14). According to the system, the the equipment number and equipment maintenance are reduced, and the occupational hazard caused by conveying the lead powder in the production process of lead-acid storage batteries is effectively eliminated or reduced.

Description

technical field [0001] The invention relates to the field of environmental protection, and more specifically relates to a nitrogen-enclosed suction-type lead powder pneumatic conveying system. Background technique [0002] With the rapid development of the automobile, shipbuilding and communication industries, lead-acid batteries, as a cost-effective power source, are also developing rapidly, and the number of employees is increasing year by year. Since more than 80% of the personnel in lead-acid battery production enterprises are in close contact with toxic and harmful substances, and the control measures are not perfect, the health of the original workers who have been exposed to harmful substances such as lead and sulfuric acid has been seriously threatened. Therefore, implementing effective control measures for lead-acid battery manufacturers to reduce the incidence of occupational diseases has become a top priority for the occupational health management of lead-acid bat...
