Abstract

The invention discloses a lead powder and nitrogen gas closed-cycle static-pressure dense-phase sectional boosting pneumatic conveying system. The system comprises a lead powder storage bin (1), a lead powder discharging device (3), a pneumatic feed valve (4), a transmitting bin pump (6), a lead powder conveying main gas source valve group (7), a discharge fluidization device (8), a bin pump discharge port boosting device (9), a pneumatic discharge valve (10), a dust conveying pipeline internal pressure sensor (11), a sectional external booster (12) with a pressure sensor, a dust conveying pipeline (13), a gas-solid separation device (14), an ultrafiltration device (15), a lead powder bin (16), a nitrogen gas return pipeline (17), a nitrogen gas storage tank II (19), a nitrogen gas recycling compression system device (21), a high-pressure nitrogen gas pipeline (23), a nitrogen gas storage tank I (24) and a system control device (25) which are sequentially connected. According to the system, the equipment quantity and the equipment maintenance load can be reduced, and the occupational risks of lead powder conveying in a lead-acid storage battery production process can be effectively eliminated or reduced.

Description

technical field [0001] The invention relates to the field of environmental protection, and more specifically relates to a lead powder nitrogen closed-circulation static pressure dense phase segmental boosting 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 occ...
