Abstract

The invention relates to a carbonization activation integrated furnace, which includes a material chamber. The top of the material chamber is provided with a feed inlet, the bottom is provided with a discharge port, and the material chamber is used for storing and transporting materials. A drying section, a carbonization section, and an activation section that are communicated are disposed between the feed inlet and the discharge port from top to bottom in order. The furnace also includes a combustion chamber disposed outside the material chamber and used for heating materials in the material chamber. The activation section of the material chamber is equipped with a steam pipeline, which has several water vapor outlets molded in the vertical direction. The setting mode of the water vapor outlets enables water vapor to contact more materials in the vertical direction, and the water vapor outlets are uniformly distributed and are easy to operate. Meanwhile, water vapor moves in the horizontal direction, thus solving the problem that the pressure of materials above limits the upward movement range of water vapor.

Description

A kind of carbonization-activation integral furnace
Technical field
The present invention relates to a kind of carbonization-activation integral furnace, specifically a kind of carbonization-activation integral furnace by the outer hot indirect heating of external combustion.
Background technology
The preparation of activated coke or gac needs use to prepare stove to complete, and is preparing in stove the process completing charing or activation, final obtained required activated coke or gac.At present, gac/Jiao prepares stove and mainly contains following form, and one is Stepple furnace, and mainly in China's application, it is for being interrupted the mode of production, and separate unit treatment capacity is low, only has hundreds of ton every year; Another kind is multiple hearth furnace, is derived from the U.S., and the body of heater shell of multiple hearth furnace is cylindrical, is rolled form by general steel plate; Inner lining refractory, stove is made to be partitioned into multistage with heterotypic fire brick or common laying fireproof bricks hearth structure, every section of siege respectively around siege and/or middle section material falling hole is set, solid materials is stirred by the stirrer gear be installed on slow speed of revolution central shaft agitating arm step by step by (then by Inside To Outside on lower floor's siege) inside lateral on siege, is entered next section of siege, the design of this stove is comparatively complicated, and very high to the equipment requirements such as central shaft, rake teeth.In addition, above-mentioned Stepple furnace and multiple hearth furnace can only complete activation, and charing needs to carry out in a separate device, increases the complicacy of production technique.One is also had to be pierce smith converter, because its material advances by body of heater self angle of inclination and oblique flight, the rate of advance of the bad control material of production lightweight charcoal, and above-mentioned activation furnace is all interior heating, combustion gases directly contact with material, inevitably cause raw material surface combustion, reduce the quality of gac, and be usually arranged on below due to the heating unit of pierce smith converter, be heated evenly so material barrel needs ceaselessly to rotate guarantee material.
In prior art, Chinese patent literature CN2535399 discloses a kind of bucket-type carbon activation furnace apparatus, comprise furnace wall, storagetank, oxidation air flue, combustion chamber, cooling zone, water vapour import, discharger, discharging hopper, blast pipe, dividing plate, side flue, exhanst gas outlet, packing, stove seat, crown cap, water seal, combustion chamber in furnace wall is arranged in order with bucket type brick to form, laterally horizontal air flue is formed between adjacent brick wall, repeatedly put up and down, vertical material road is formed between brick hole, joint, brick hole forms venting port, horizontal air flue communicates with the side flue being provided with blast pipe, dividing plate is divided into arid zones combustion chamber, carbide bound, activation zone, bucket type brick is the hollow brick of outer image bucket, the upper surface of brick is square, brick hole inwall section is trapezoidal, brick inwall arranges leg.Described bucket type brick is profile is round table-like hollow brick, and the upper surface of brick is square, and brick hole inwall section is trapezoidal, and brick inwall arranges leg.Described bucket type brick is the hollow brick of outer image bucket, and the upper surface of brick is square, and brick hole inwall section is trapezoidal, and brick wall face, front and back is vertical surface, and brick wall face, left and right is inclined-plane.The oxidation air flue of oxygenizement has been set on combustion chamber top.Water vapor inlet mouth is arranged on the bottom of cooling zone.Exhanst gas outlet is arranged on bottom of furnace body side flue or is arranged on body of heater top side flue.
The vertical material road of above-described bucket type brick composition, there is opening joint, brick hole, make the volatile matter of material after being heated can precipitate into horizontal air flue, this structure makes partial material be directly exposed in smoke chamber, when volatile matter is separated out, can partial material be brought in smoke chamber, pollute and the waste of raw material, flue gas directly contacts the burning that can cause material with material simultaneously, affects the quality of gac; And the water vapor as activator needed for above-mentioned activation zone, its inlet mouth is arranged on the bottom of cooling zone, water vapor needs to pass through cooling zone, reduction temperature of charge becomes superheated vapour and enters material road activation zone after heat exchange, material is activated, because water vapor enters activation zone from bottom, water vapour moves from the bottom to top, be subject to the inhibition of top pressure and material, water vapor upwards range ability is little, so just limit the scope of activation zone, activation efficiency is reduced, thus have impact on the production efficiency of product.Although the activating apparatus of described pierce smith converter is inserted into material barrel inside, but just spray water vapor by activating apparatus top end opening, make water vapor diffusion even by the rotation of material barrel, in addition, body of heater rotates need use very large power, and the complex structure of this body of heater.
Summary of the invention
Technical problem to be solved by this invention is that in prior art, activator feedway is arranged on below activation section, water vapor upwards range ability is little, have impact on range of activation and activation efficiency, thus provide one that water vapor can be made to be uniformly distributed at described activation section, thus improve the carbonization-activation integral furnace of activation efficiency.
