Abstract
A vibration feeder is a piece of equipment for rationing and conveying powder, particle and block materials. In order to test the regeneration performance of de-dusting medium for high-temperature coal gas, a set of de-dusting medium-feeding systems was designed quantitatively. The de-dusting medium-feeding system is used in the gasification process for cleaning coal gas. The system is mainly composed of a hopper unit, control unit and feeding unit. In order to optimize the feeding stability of the coal-gas dust-removal medium vibration feeding system, the setting and scope of the following design factors and operating factors are investigated. Specifically, it includes the influence of gate-valve-opening adjustment of the control unit on the feeding stability of a vibrating feeding system; the influence of the gap size of the dipleg of the control unit on the feeding sensitivity of the vibration system; the influence of the particle size of the de-dusting medium on the operating range of the vibrating feeding system; the influence of the digitization of the working-current indicator of electromagnetic vibrating feeders on measurement variation and the process variation of a vibration feeding system. This vibration feeding system can realize the function of precise and quantitative feeding of the de-dusting medium, which can meet the design requirements of subsequent experimental research.
