Description
First, technical field
Patent of the present invention is related to preparing the activation method and equipment of activated carbon, especially a kind of steam activation system activity
The method and its vertical activation furnace of charcoal.
2nd, background technology
The principle of vapor activation preparing active carbon is:At high temperature charcoal and vapor carry out priming reaction generate hydrogen,
Carbon monoxide, carbon dioxide, make charcoal particle generate flourishing pore structure, and the effect of activation furnace is just to provide charcoal under hot conditions
The place of priming reaction occurs with steam, the requirement to activation furnace is exactly to maintain the condition of high temperature of region of activation, activates steam and charcoal
Expect that active area is larger in region of activation more uniform distribution, activation is uniform, and activation effect is good, and can realize that continuous mechanized feeds
And discharging.At present, the activation furnace that vapor activation prepares activated carbon mainly has vertical Slapple activating furnace and swinging to live
Change two kinds of stove, there is following shortcomings for vertical Slapple activating furnace:The activation furnace has the steam of left and right two to preheat half stove, in work
Changing needs two steams of progress to preheat being switched with vapour and pre- Warm status for half stove during operation, operate cumbersome, operating technology requirement
It is higher;Slapple activating furnace is complicated, and construction investment is big, repair trouble.For another example application No. is 201410373019.0 it is special
Sharp " efficient vertical pipe type activation furnace ", it is characterized in that activation tube is pipe, it is spaced apart to lead to activation vapor in activation tube,
By the material in pipe pipe heater outside, there is activation tube central temperature is lower than activation tube outer rim temperature, temperature of charge is uneven
And cause to activate non-uniform shortcoming;In addition, material is moved down by gravity, there is putty.Swinging activates
The characteristics of stove is that raw material is added in from one end of horizontal shaft, and with the rotation of shaft, material is thus lifted to eminence from lower and falls,
Slowly to the other end move, thickness of feed layer it is uneven and cause to activate it is uneven, activate steam and charcoal material contact area it is smaller,
Activation effect is not good enough.So, it is also very desirable to the contact area for activating steam and charcoal material is larger, and activation effect is good, easy to operate
Activation equipment.According to above-mentioned background, invention a kind of method with steam activation preparing active carbon and its vertical activation
Stove.
