Certain gradient, activated material is drawn off from other end burner, the material in the flue gas cartridge heater that burner is produced with fuel combustion,
Heating flue gas and material reverse movement.Because material can only be deposited in the bottom of converter barrel, the contact surface of material and flue gas
Very limited and most thick in the bed of material of bottommost, the non-uniform temperature of the bed of material of product；Cylinder is unfit to do very big, maximum gauge
For 2.0 meters, the activation yield of unit length is not big enough, and activation yield is mainly determined by the diameter of rotary furnace, length and rotating speed,
In order to improve the activation yield of rotary furnace, it is necessary to process converter barrel very long, such as more than 30 meter, need for cylinder to make two
Section, is spliced when then installing at the scene, and installation difficulty is larger, and converter weight is big, and power consumption is big.In soak time and work
Change temperature certain in the case of, in order to improve the activation yield of activation furnace, should increase activation furnace for stack the area of raw material with
Increase held inventory in stove.According to such technical background, the present invention devise a kind of raw material stack area larger, activation
The multilayer link plate type activation furnace of the higher producing activated carbon by chemical method of yield.
3rd, content of the invention
A kind of multilayer link plate type activation furnace of producing activated carbon by chemical method of the present invention, it is by rectangle activation furnace shell and many
Layer chain board conveying mechanism composition, installs 2～4 multilayer link plate type conveyers in rectangle activation furnace shell and waits to live for transmitting
The material of change, can determine quantity and the conveyer belt number of plies and its length of material conveyor according to output demand, and the conveyer belt number of plies is 3
～5 layers, conveying bandwidth is that 0.5～1.0 meter, length is 10～40 meters.Conveyer belt is arranged on live-roller (5) and carrying roller (7),
Live-roller and carrying roller are on support (12).Loading hopper (9) is set at the top of activation furnace shell, is pacified in loading hopper discharging opening
Dress at the uniform velocity feeder (10), material is at the uniform velocity added on the conveyer belt in activation furnace, by buncher and reduction gearing mechanism
Live-roller operating is driven, makes conveyer belt for linear motion, the material of upper strata conveyer belt is sent on next layer of conveyer belt successively.With
The operation of conveyer belt, on each layer conveyer belt, is equably paved with material.In activation furnace discharge end bottom, heating flue gas is set
Passage, is passed through the activation tail gas from Physical activation furnace into housing and makees heating medium, the wood flour phosphoric acid on conveyer belt is mixed
Compound is progressively heated and obtains carbonization and activation, arranges fuel burner nozzle in activation furnace discharge end, for burning when furnace temperature is too low
Heating.The activated material for completing charcoal activation carries out continuous discharge from the conveyer belt tail end of basecoat and is stored in charging basket.Can basis
The adsorptive value of prepared activated carbon makes material stop reasonable time in activation furnace to guarantee adjusting the speed of service of conveyer belt
The absorption property of activated material reaches required index request.The multilayer link plate type activation furnace has activation yield greatly, available
Physical activation tail gas is made heating medium and saves energy consumption, and soak time is easily adjusted, the feature of product quality easy-regulating.The multilamellar
Chain-plate type activation furnace can be not only used for bamboo wood chip phosphoric acid method production powdered activated carbon, it can also be used to which the production of pit shell phosphoric acid method is unsetting
Granular active carbon.
