Description
Technical field
The invention belongs to active carbon carbonized material production equipment field, in particular to a kind of efficient inside and outside dual-heating mode turns round charcoal
Change furnace.
Background technique
Activated carbon product is many kinds of, is widely used in military chemical defence, space flight and aviation, air cleaning, water body purification, change
The wide fields such as work synthesis, solution are recycled, medicine purifies, food decolourizes, Industrial " three Waste " is administered, using active carbon as carrier manufacture
Catalyst be military " coring raw " protective equipment core material.Since its is acidproof, alkaline-resisting, heat-resisting, and after adsorption saturation
Regeneration can be facilitated, play increasingly important role in protection environment for human survival.Active carbon is according to raw material difference, activity
Charcoal can be divided into wooden active carbon, shell class active carbon, active carbon from coal and petroleum coke active carbon etc..Coal base or wooden carbon containing original
Material carries out carbonization process, usually Low Temperature Pyrolysis Process (500~600 DEG C), be before activation be primarily intended for and basis, by charcoal
The carbonized material of change process has a great impact to the quality of final products active carbon.
Equipment used is revolution retort when charing, and revolution retort is divided into internal heat type and two kinds of external-heat.Interior heat
Formula revolution retort then has simple structure, technology controlling and process and easy to operate easy, thermal efficiency height, makes material by rotating mixing
Be evenly heated, heating rate rationally, uniform quality, furnace atmosphere is easily controllable, product yield is high, product strength is high, yield is big,
The advantages that continuous production is stable, therefore active carbon from coal manufacturing enterprise is widely used that internal heat type revolution charing at present
Furnace.The working principle of internal-heated rotary furnace is that heat medium and the material carbonized continuously directly connect within the scope of certain temperature
Touching, mutual reverse flow.Material is mobile from low-temperature space to high-temperature region, and reverse and next heat medium is constantly by heat aliment
Material, temperature of charge steps up, so that the processes such as dehydration, degassing, drying, thermal decomposition, thermal polycondensation are completed, finally from high-temperature region
Discharge port discharge；Heat medium is mobile from high-temperature region to low-temperature space, and since heat is constantly supplied material, own temperature gradually drops
A large amount of volatile matters that are low and carrying material generation in carbonization process, are finally exported by furnace exit gas and are discharged.Traditional external-heat returns
Turn retort due to structure is relative complex, cost is higher, the thermal efficiency is low etc., has been rarely employed now.Traditional outer heat
Formula turns round retort due to structure is relative complex, cost is higher, the thermal efficiency is low etc., has been rarely employed now.It is novel outer
Traditional mode of the heating revolving retort due to breaching revolution retort in process and structure, production capacity and the thermal efficiency
Significantly larger than traditional inside and outside heating revolving retort.
The patent document that number of patent application is CN103787306A discloses a kind of external heat and turns round retort, in the patent
Active carbon charing raw material be not directly contacted with flue gas, the combustion gas as caused by activation furnace through combustion chambers burn generation 500~600
DEG C flue gas retort is entered by burner, external-heat returns inside retort using stainless-steel pipe conveying charing raw coal, stainless steel
Length of steel pipe is equal with rotary furnace entire length, and active carbon charing raw material is not directly contacted with flue gas, so can effectively avoid
Material is accumulated higher in furnace tube under equal production volume in internal heat type retort, and ejection height is larger, and material uneven heating is even and grinds
It is higher to damage and beat percentage of damage, carbonizes the problems such as finished product yield is low.But in operation process inside the external-heating revolving retort
In there are tar in furnace in raw material blockage, furnace tail sealing material is not up to standard, and production capacity is not up to standard, brings inconvenience to next step activation
The disadvantages of；When production capacity increases, the volatile matter of active carbon raw coal is largely precipitated, and can largely be blocked up in stainless-steel pipe furnace tail region domain
Plug causes part obstructed, seriously limits the production capacity of complete equipment, while causing the quality of activated carbon of production not up to standard.
