The invention discloses a gear type powdered coal pressurized conveying device. The device comprises a drive gear, a driven gear, a powdered coal inlet, a powdered coal outlet, a shell and a wiper; the drive gear and the driven gear are arranged in the shell, and the drive gear is meshed with the driven gear and conveys powdered solids to the powdered coal outlet from the powdered coal inlet; the wiper removes attachments attached to the surface of the drive gear and the surface of the driven gear. According to the gear type powdered coal pressurized conveying device, the problems that in the prior art, great environment pollution is caused by the fact that a large amount of inert gas needs to be exhausted, the pressurized conveying process is low in efficiency and not continuously adjustable, energy consumption is high, and due to the fact that high-pressure-resistant equipment is needed, the device is large in size and high in cost are effectively solved.
Description
technical field [0001] The invention relates to the field of pulverized coal pressure conveying, in particular to a gear type pulverized coal pressure conveying device. Background technique [0002] In coal chemical industry, metallurgy, food processing and many other fields, the process of pressurized conveying of powder is involved. Coal gasification, especially pulverized coal pressurized gasification is a clean coal utilization technology, which has been developed rapidly in recent years and has been used more and more widely. Pulverized coal pressurized conveying technology is an indispensable technical link of pulverized coal pressurized gasification technology. Pulverized coal pressurized conveying technology is to increase dry coal powder from normal pressure to a specific high pressure, so as to realize the combustion and gasification of pulverized coal under high pressure. [0003] The pulverized coal pressurized conveying technology currently used in industry is...
