Abstract

The utility model provides activated carbon rinsing equipment which is used for rinsing semi-finished activated carbon during the activated carbon production. The equipment has a main body 5 which adopts a cylinder structure and is made of heat-resistant and acid-resistant sulfonic polymer, and a filter plate 2 made of sulfonic polymer is installed inside the cylinder; a vacuum connecting pipe 3 is mounted on a cylinder body under the filter plate so as to vacuum filter a mix of carbon and water; a water discharge outlet 1 and a valve are arranged on the wall at the bottom part of the cylinder body so that switching between water draining and rinsing can be controlled; compressed air connecting pipes 6 and 7 are installed in proper positions on the cylinder body above the filter plate at a fit angle with respect to the tangent line of the cylinder body, and a cross-shaped compressed air tube 8 is installed on the filter plate for compressed air to enter and to stir the mix of carbon and water; a steam pipe 4 is connected to a proper position on the cylinder body above the filter plate, in order that the mix of carbon and water can be heated; and a discharge port and a discharge door capable of being quickly opened and closed are installed on the wall of the cylinder body above the filter plate, so that switching between discharging and rinsing can be accelerated.

Description

A kind of gac rinsing equipment

One, technical field

The utility model relates to being used in the Activated Carbon Production process and removes or reduce ash content, iron, calcium, magnesium etc. and other foreign matter content of gac, and improves the rinsing equipment of charcoal absorption performance.

Two, technical background

For the content of the ash content that reduces activated carbon product and iron, calcium, magnesium etc. and other impurity to improve the quality of product, in the Activated Carbon Production process, require the work in-process gac is carried out rinsings operations such as pickling, washing, require rinsing equipment heat-resisting, corrosion-resistant.Because wanting the gac of rinsing is fine particle shape or powdery, rinse cycle need be through repeatedly heating, stirring, the charcoal repeatable operation with operations such as separating of water, charcoal is difficult with separating of water, gac is in water behind the standing sedimentation, it is very big to reset the required power of agitator, and mechanical stirring can't realize.China also do not possess at present heating, stirring, charcoal and water separate with quickly discharging four big functions in the more convenient gac rinsing equipment of the operation of one, the rinsing task of Activated Carbon Production enterprise is by hand mixing and water vapor boiling in many ceramic cylinders or in the rinsing bath of surface lining acid resisting material, drain behind the isoreactivity charcoal standing sedimentation again water on upper strata, through repetitive process so repeatedly, carry out in the filter bag of packing into through vacuum filtration or the very high charcoal of water content more at last that centrifuge dehydration finishes.Such rinsing process exists that troublesome poeration, throughput operator little, that need is many, labour intensity big, production environment is poor, product loss and water loss is big, stirring is inhomogeneous causes many shortcomings such as quality product is inhomogeneous, wash effect is poor, floor space is big.

Three, utility model content

The purpose of this utility model provides a kind of easy to operate, and wash effect is good, the production efficiency height, and labour intensity is low, the novel absorbent charcoal rinsing equipment that production environment is good.Rinsing equipment is cylindrical structure, has four big functions such as heating, stirring, charcoal and water sharp separation, quickly discharging, and acidproof, heat-resisting.The rinsing equipment body is a tube structure heat-resisting, that acid proof sulfone polymeric material is made.If gac is used mechanical stirring behind the standing sedimentation in water, its resistance is very big, the agitator starting difficulty, and rinsing equipment of the present utility model adopts pressurized air to stir the mixture of charcoal and water; Mixture with steam heating charcoal and water; Utilize vacuum filtration to realize the sharp separation of charcoal and water; Finish rinsing and the gac after suction filtration blots and carry out discharging by the lateral discharge door that can open and close fast of rinsing tube.Realize air compressor of rinsing manipulation require and the vacuum pump and the steam of pressure more than 0.1MPa of gac.

Four, description of drawings

Fig. 1 is the facade view of rinsing tube, and (1) is the filtrate relief outlet; Overhead install by the screen plate (2) heat-resisting, that acid proof sulfone polymeric material is made at 0.5-0.7 rice in cylindrical shell; Place the acidproof filtering net of 50-100 purpose on the screen plate; " ten " font compressed air pipe (8) is installed on screen plate, perforate on its appropriate location, and connect vertical with tube axis and become the thrust-augmenting nozzle at 30-60 ° of angle with tubular axis, so that in tube, feed pressurized air, promote the rotation of charcoal and water mixture, produce the effect of stirring; (3) be the valve tube interface, be used to connect vacuum apparatus; (4) be the steam pipe interface, be used for water flowing steam heating material; (5) be the rinsing equipment barrel; (6), (7) are the pressurized air interface tube.

Fig. 2 is the sectional view in A-A cross section among Fig. 1, and (1), (5) are the steam pipe interface; (2), (3), (6), (7) are for being installed in the pressurized air interface tube that becomes 30-45 ° of angular direction to be provided with the cylindrical shell wall around and with tangent line, two-layer setting about compressed air pipe divides, angle at 45 is staggered on the cylindrical shell wall.Compressed air pipe axis and tangential direction are angled, and charcoal and water mixture material are produced the thrust of tangential direction, and the effect that the performance rotation is stirred reaches abundant rinse-active charcoal, reduce the grade purpose of impurity of its ash.

Fig. 3 is and the vertical facade view of Fig. 1 place section that (1) is the gac discharge opening; (2) be the energy Dump gate of opening and closing fast; (3) be the blow-off valve interface.

Fig. 4 is and Fig. 3 place section facade view at 45 that (1), (2) are interface of the level gauge, need to judge whether draining so that the height of liquidometer observation water level is installed.

Five, embodiment

The diameter of rinsing tube and height can design according to rinsing output, and in general, diameter should be at 1.0-3.0 rice, and height should be at 1.8-2.5 rice, and more suitable diameter is a 1.5-2.0 rice.The rinsing operation is to implement like this: add entry to flooding the upper strata compressed air pipe in the rinsing tube, add the technical hydrochloric acid that accounts for charcoal amount about 10%, start air compressor, open the pressurized air tube valve, in rinsing tub, feed pressurized air, the steam valve of fetching boiling water, feed water vapor, add gac then and carry out the rinsing operation, treat closes compression air and water vapor behind the rinsing certain hour, open vacuum pump the mixture of charcoal and water is carried out vacuum filtration, the water level that gets off when suction filtration is closely closed vacuum pump, opening water discharge valve and blow-off valve soon during the valve tube interface, open vacuum pump again after the water that suction filtration is got off has all been arranged and carry out suction filtration, and then draining, repeated multiple times like this is until water is drained.Then through adding water, rinsing, suction filtration and draining operation so repeatedly again, reach about 5-7 up to the pH value of gac.At last the water suction filtration is blotted, open discharge door and unload charcoal, gac is transported to baking operation dries.
