一种煤粉稳流输送装置及输送方法
本发明公开了一种煤粉稳流输送装置及输送方法，是利用惰性气体包括氮气和二氧化碳密相气力输送干煤粉至加压气化炉，以获得密相加压煤粉稳定流速；该装置包括给料罐、给料罐锥体、通气锥、隔板、夹块、输送管线和布风板；在煤粉给料罐的锥体部位焊接夹块，夹住隔板，将锥部内空间分隔成若干个下料空间；该方法可稳定地分别向两条甚至多条煤烧嘴输送煤粉，避免因煤粉输送量的波动给引起气化炉内温度的不稳定而影响正常气化运行和设备损坏，也节约了投资成本。 The invention discloses a steady-flow conveying device for pulverized coal and a convey...

The invention discloses a steady-flow conveying device for pulverized coal and a conveying method. Dry pulverized coal is conveyed pneumatically to a pressure gasifier in a dense-phase manner by inertgas containing nitrogen and carbon dioxide, so that steady flow rate of dense-phase pressure pulverized coal can be obtained. The device comprises a feed tank, a feed tank cone, an aeration cone, partition boards, clamp blocks, conveying pipelines and an air distribution plate, wherein the clamp blocks are welded at a cone part of the pulverized coal feed tank and clamp the partition boards, andinner space of the cone part is separated into a plurality of discharge spaces. With adoption of the method, the pulverized coal can be stably conveyed to two or more coal nozzles, influence on normalgasification |
