Description

A kind of with core class charring material production process of active carbon

Technical field

The present invention relates to a kind of Activated Carbon Production equipment, particularly relate to a kind of equipment of producing gac with core class charring material.

Background technology

Gac is the important materials of multiple industry and environmental protection industry (epi), and market demand grows with each passing day, and particularly shell class gac is more well sold and in short supply.The main process of producing shell class gac is that raw material is carried out charing and activation at a certain temperature, makes it reach the regulation physical and chemical index.At present, produce gac and adopt process furnace more, and be stove to be built into refractory materials, its structure comprises charging opening, charing section, activation section, discharge port and steam plenum system and flue system, existing problem mainly contains: (1) discharges a large amount of smog, and environmental pollution is more serious; (2) furnace binding complexity, the maintenance difficulty; (3) be difficult to realize automatic continuous production, production efficiency is low; The method of producing the used heating of gac generally has two kinds: the one, and coal, the one,, as heating material, gac per ton need consume 1.2 tons in coal with coal, and a large amount of fume emissions are arranged, the severe contamination that causes to periphery, electricity consumption is as heater means, except current consumption greatly because furnace binding is unreasonable, fruit stone discharges a large amount of smog in combustion processes, environmental pollution is more serious.Present several activation furnaces commonly used, as the smoldering stove, Si Liepu ature of coal activation furnace and 288 type activation furnaces etc. all are high energy consumption, seriously polluted, big, high, the baroque type of furnace of product cost of investment, wherein, seriously polluted problem is the main contents that local government requires rectification.For this reason, with serious pollution problem is the main task that manufacturing enterprise faces in the solution Activated Carbon Production process.Disclosed in ZL200720102965.7 " a kind of environmental protection, energy-conservation, efficient activation oven for active fruit shell carbon " and disclosed in ZL200820076149.8 " a kind of efficient, energy-conservation absorbent charcoal activation furnace ", all be by improving the structure of charing section, activation section in the body of heater, make sufficient combustion in the gac normal productive process, reduce the discharging of flue gas, use through reality, effect is pretty good, but do not change the stove form, make the furnace binding complexity, the problem of maintenance difficulty and be difficult to realize that the problem of automatic continuous production does not obtain basic solution.

Summary of the invention

The present invention is directed to the deficiencies in the prior art; a kind of equipment of producing gac with core class charring material is provided; this equipment is raw material with the core class charring material; adopt microwave heating; realize automatic continuous production; technical problem to be solved is that raw material is continuously activated by heating region; and arrange rationally that steam is supplied with and gas protection system; this device structure is reasonable; energy-conservation; environmental protection; the production efficiency height; constant product quality; the technical solution used in the present invention is as follows: the utility model is by body of heater; the ingredient conveyor structure; charging opening; heating zone; steam supply and gas protection system and Material collecting box for harvesting are formed; it is characterized in that body of heater is a sealed hollow; one end is charging opening; the other end is Material collecting box for harvesting; the conveying belt that is provided with portless between charging opening and the Material collecting box for harvesting is used for carrying carbonized material; carbonized material is exposed in the micro-wave energy; microwave office is an airtight obturator; to prevent microwave leakage; this obturator comprises that a centre chamber is to provide microwave heating; also comprise two transfer passages that stretch out from centre chamber; carbonized material is placed on the conveying belt of first transfer passage end through opening for feed; pass centre chamber with conveying belt; enter Material collecting box for harvesting from the conveying belt of another transfer passage end; the Material collecting box for harvesting casing is sandwich structure; it is the water coolant that flows in the interlayer; centre chamber is divided into a plurality of heating chambers; comprise carbonized material preheating chamber and activating chamber, each heating chamber is established independent exhaust outlet and nitrogen input aperture, and in each activating chamber vapour generator is set.

Mechanism of the present invention:

Carbonized material adds from opening for feed; and be placed on the conveying belt of continuous movement with the form of surface bed layer; the surface bed layer can guarantee the quick and even of microwave heating; carbonized material on the conveying belt at first enters preheating chamber through transfer passage; preheating temperature is 500～800 ℃; be 2～5 minutes warm up time; make carbonized material after preheating chamber is heated to the desired temperature of charing, enter activating chamber; activation temperature is 900～1000 ℃; soak time is 4～10 minutes; the speed that conveying belt moves can determine that to guarantee activation effect, the activation back enters Material collecting box for harvesting by transfer passage and is collected according to the length of preheating chamber and activating chamber and the requirement of soak time.

Compared with prior art, the present invention adopts the conveying belt mode can reduce relative movement between carbon granule greatly, particularly in the microwave high-temperature district, there is relative movement hardly, the charcoal loss amount reduced, in addition, moving belt can be realized automatization control, realizes producing continuously, enhances productivity.
