气力输送固体颗粒物料的方法,由于具有自动、连续、外泄尘粒较少以及工程系统简单等优点,往往人们乐于采用。在活性炭生产中,炭化料(木炭)的输送正是采用负压气力输送的,其基本数据和流程示意图如下(见图1和表1)。在输送管下端用皮带输送机传送轧制后的炭化料,让输送管尽量均匀地吸入,以保证在输送管中有比较稳定的固气比;而调节皮带输送机的速 Pneumatic conveying of solid particulate material, because of the automatic, continuous, less dust particles and the advantages of simple engineering systems, often people are happy to use. In the production of activated carbon, charcoal (charcoal) is transported with negative pressure and its basic data and flow chart are as follows (see Figure 1 and Table 1). At the lower end of the conveying pipe, the belt conveyor conveys the carbonized material after rolling so as to uniformly suck the conveying pipe as much as possible so as to ensure a relatively stable solid-gas ratio in the conveying pipe. The speed of the belt conveyor is adjusted
