Problems solved by technology

[0003] The main equipment for producing activated carbon includes rake furnace, multi-tube furnace, Sleep furnace, rotary furnace, smoldering furnace, fluidized fluidized furnace, etc. Different equipment has requirements for raw materials, furnace specifications, and investment costs in the process of producing activated carbon. And the performance of the final activated carbon product has different advantages and disadvantages, but their overall characteristics are high energy consumption in the production process of activated carbon, a large amount of high temperature and waste heat, smoke and harmful gases are generated after high temperature reaction, and the processing cost is high and difficult. If It is directly discharged into the atmosphere through the chimney, which not only reduces the energy utilization rate, but also causes environmental pollution

Embodiment 1

[0046] This embodiment is used to describe the equipment for the production of activated carbon of the present invention in detail.

[0047] Depend on figure 1 As shown, an activated carbon production equipment includes a steam generating device 1, a high-temperature pyrolysis reaction device 2, and an integrated condensing device 3, and the above devices are connected to each other in sequence.

[0048] The steam generating device 1 mainly includes a fully automatic electric heating steam generator 11. The steam generated passes through the safety valve 12, the ball valve I13, the pressure reducing valve 14, the first pressure gauge 15, and the flow meter 16 to form steam with relatively stable pressure and flow rate. The first steel wire bellows 17 is connected with the ball valve II21 in the high temperature pyrolysis reaction device 2; the steam enters the rotary kiln 23 through the four-way valve 22 connected with the ball valve II21 in the high temperature pyrolysis reac...

Embodiment 2

[0051] see figure 1 and figure 2 .

[0052] (1) Raw material preparation and program setting stage: Add the processed wood chips into the rotary furnace 23, close the feeding port, and set the heating rate and temperature range of the rotary furnace 23. Among them, the first stage: the heating rate is 10°C / min, and the temperature range is 0-600°C; the second stage: the heating rate is 10°C / min, and the temperature range is 600-1200°C; the third stage: stop heating and start the cooling program.

[0053] (2) Charcoal activation and reactant collection stage: open the ball valve IV24, close the ball valve II21, open the protective gas entering from the protective gas storage tank 26, and pass the high-temperature waste gas generated in the first stage of the reaction through the condensation rotary sleeve 301 and the quick-connect clamp 302 are introduced into the integrated condensing device 3 by the second steel wire bellows 303, and through the integrated cooling water ta...

Embodiment 3

[0056] (1) Raw material preparation and program setting stage: Add the processed wood chips into the rotary furnace 23, close the feeding port, and set the heating rate and temperature range of the rotary furnace 23. Among them, the first stage: the heating rate is 5°C / min, and the temperature range is 0-500°C; the second stage: the heating rate is 10°C / min, and the temperature range is 500-1200°C; the third stage: stop heating and start the cooling program.

[0057] (2) Charcoal activation and reactant collection stage: open the ball valve IV24, close the ball valve II21, open the protective gas entering from the protective gas storage tank 26, and pass the high-temperature waste gas generated in the first stage of the reaction through the condensation rotary sleeve 301 and the quick-connect clamp 302 are introduced into the integrated condensing device 3 by the second steel wire bellows 303, and through the integrated cooling water tank 304, the material that can be cooled is...
