Abstract
The utility model relates to the improvement of a rotary internal heated activation furnace, comprising a cylinder and a combustion chamber. A multi-grate products channel is arranged in the inner diameter of the cylinder; a secondary air distribution device comprises a blower fan, a secondary wind pipe, a control valve and a superheating tube; preheated secondary wind is applied in the rotary furnace for regulating the temperature of an activating band in the furnace. Because the products channel forms a multi-grate type, the residing time of material in furnace is prolonged under the conditions of equal length and equal speed; in addition, the secondary air distribution device can well regulate and control the temperature of the activation band to make material be sufficiently activated; thereby, the yield and the product quality of products are improved. The utility model has the advantages of convenient operation and low maintenance cost; the utility model can start and shut down the furnace at any time.
Description
The utility model belongs to gac producing apparatus field, particularly the improvement of revolution internal heat type activation furnace.
The used equipment of existing production active carbon finished products mainly is Stepple furnace, and products material adds from the top, at regular time and quantity from the furnace bottom discharging.Reconcile furnace temperature, quantity of steam and timing discharging time according to product index.The problem that this stove exists is that the initial stage facility investment is bigger, need pile up by more than 30 kind of heterotypic fire brick, and blow-on need reach more than 30 day warm stove intensification, must fill carbonized material in the product channels in the blow-on forehearth, so the raw material burning is lost seriously, wastes too big.Product channels was easily stopped up during this stove used, and to burn the stove time long in addition, and blowing out, blow-on cycle are long, easily cause body of heater to damage the work-ing life of having reduced body of heater.
The purpose of this utility model is some weak point at existing absorbent charcoal activation furnace, activation furnace has been done improvement, be provided with the multi-format product channels that has the secondary air distribution device, prolonged the residence time in the product stove thereby play, increase heating surface area, improve the effect of product yield.
The technical solution of the utility model is such.Activation furnace multi-format product channels and secondary air distribution device comprise cylindrical shell and combustion chamber, and cylindrical shell is connected with the combustion chamber.Be provided with the multi-format product channels in the cylinder internal diameter, product channels cross section checkerwork cell is four holes, five holes or vesicular, separated by stiffening web between checkerwork cell, stiffening web and conduit wall are that the product channels of integral casting forming is the segmentation shape and is arranged in cylindrical shell, and both sides, secondary air distribution device that two sections passages are positioned at the burning mixing section comprise blower fan, secondary air channel, by-pass valve control and superheater tube.The leading portion that is arranged in the secondary air channel on the cylindrical shell passes barrel wall to product channels, and back segment is connected with superheater tube, and cooling room is connected with the tail end of superheater tube, and the by-pass valve control of regulating the air quantity size is housed on the secondary air channel.In rotary kiln, apply the secondary air after the preheating, be used for regulating activation zone temperature in the stove.When rotary kiln moved in negative pressure, secondary air at first by the annular cooling chamber of burner, tail sealing device, was sent into the stove middle part by the further heating of superheater tube that is embedded in the stove inner thermal insulating layer after the preheating by the nature draft.Rotary kiln is when operation under positive pressure, and secondary air is by the outer blower fan air-supply of stove.
The utlity model has following effect:
1. owing in the rotary kiln cylindrical shell, be provided with the cellular product channels of multi-format, thereby increased the contact area of work in-process (activated material), under isometric constant speed, prolonged the residence time of material in stove with activated media, make it abundant activation, the quality of activated carbon of producing obtains bigger raising.
2. by the configuration overfire air device, can well regulate and control the activation zone temperature, soak time is short under same product situation, and it is obvious to improve the product yield effect.
3. the utility model reaches the improvement to whole activation furnace by improving product channels and configuration secondary blast device, makes activation equipment be convenient to operation, upkeep cost is low, blow-on and blowing out are more prone to, and blow-on at any time and blowing out, and the device fabrication expense is 2/3rds of a An Shi stove.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Fig. 1 structure A-A diagrammatic cross-section.
Fig. 3 is Fig. 1 structure B-B diagrammatic cross-section.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
As shown in the figure, component structural of the present utility model is: 1-shell 2-cylindrical shell 3-multi-format product channels 4-fuel mixing chamber 5-by-pass valve control 6-secondary air channel 7-stand-by fan 8-superheater tube 9-rotating seal ring 10-annular cooling chamber 11-combustion chamber 12-blower fan 13-stiffening web 14-conduit wall
From the figure as can be seen, cylindrical shell 2 is connected with combustion chamber 11, add cellular multi-format product channels 3 in the cylindrical shell 2, product channels is built by laying bricks or stones or is fired with special shape refractory brick combination and forms, the channel cross-section checkerwork cell is four holes, five holes or vesicular, separated by stiffening web 13 between checkerwork cell, stiffening web 13 is arranged in the both sides that 2, two sections passages of cylindrical shell are positioned at burning mixing section 4 with conduit wall 14 for whole product channels 3 of building moulding by laying bricks or stones is the segmentation shape.The secondary air distribution device is housed on the cylindrical shell 2, and the secondary air distribution device comprises blower fan 12, secondary air channel 6, by-pass valve control 5 and superheater tube 8.The leading portion that is arranged in the secondary air channel 6 on the cylindrical shell 2 passes barrel wall to product channels 3, back segment is connected with superheater tube 8, the blower fan 12 that is installed on the tube wall is connected with annular cooling chamber 10, cooling room 10 is connected with the tail end of superheater tube 8, by-pass valve control 5 is housed on the secondary air channel 6, and the stand-by fan 7 that is connected with superheater tube 8 with secondary air channel 6 uses when preventing that blower fan 12 is out of order.Rotating seal ring 9 is in order to the annular cooling chamber on the sealing bore body wall.Be surrounded by metal shell 1 on the cylindrical shell 2, shell 1 is welded for high temperature steel.
