Description
Technical Field
The invention relates to the technical field of active carbon rinsing process production, in particular to efficient rinsing equipment for active carbon production and a rinsing method thereof.
Background
The active carbon is a black porous solid carbon, and is produced by crushing, molding or carbonizing and activating uniform coal particles; the main component is carbon, and contains a small amount of oxygen, hydrogen,Sulfur, nitrogen, chlorine, and the like. The specific surface area of the common active carbon is 500-1700 m 2 Between/g; has strong adsorption performance and is an industrial adsorbent with extremely wide application; at present, the preparation method of the activated carbon is mainly a chemical activation method, the phosphoric acid activation method is a common chemical activation method for preparing the activated carbon, in the production process of the phosphoric acid method, for example, coconut shells are used as raw materials, phosphoric acid is used as an activating agent, the raw materials of the coconut shells and 60% phosphoric acid with mass fraction of 60% are uniformly mixed according to a dipping ratio of 1:1-3:1, after heating pretreatment at 150-300 ℃, the activated carbon is activated in an activating device, the activating temperature is 300-500 ℃ and the activating time is 1.5-2.5 h, and the activated carbon is prepared after cooling to room temperature, rinsing, drying, crushing and sieving.
The activated carbon is rinsed and dried, and various impurities from the raw material activation production process are removed, so that the contents of chloride, total iron compounds, ash and the like and the pH value of the activated carbon reach regular indexes; the traditional activated carbon rinsing and drying processes are carried out separately, corresponding transfer equipment needs to be added to connect the two treatment processes, so that the preparation cost investment is increased, the production and processing efficiency of the continuous production of activated carbon rinsing and drying is low, and the activated carbon is rinsed by adopting a soaking mode, so that activated carbon is soaked in a rinsing liquid after being activated, the activated carbon washing contact area is easy to be small, the washing is insufficient, meanwhile, the activated carbon is not washed cleanly, the impurity content is high, the activated carbon rinsing effect is poor, and the impurity removal amount of the rinsed activated carbon is influenced.
In the prior art, the 'quick water rinsing and dewatering integrated device for preparing granular activated carbon' disclosed by the publication No. CN113582178B is used for rinsing activated carbon through a rinsing component, filtering the activated carbon through a filtering component, and accelerating the vibration frequency of a rinsing cylinder under the action of a vibration component, so that the rinsing is complete, hot air is blown in from all directions through a drying component, the activated carbon can be sufficiently dried, the raw material loss is reduced, the production cost is reduced, the workload of workers is reduced, and the device is convenient to use; however, the following problems exist in the actual production process:
1. the rinsing component and the vibration component are combined to enable the rinsing cylinder to reciprocate in the vertical direction, so that the phenomenon that active carbon in the rinsing cylinder is deposited at the bottom of the rinsing cylinder to cause insufficient rinsing is avoided; however, the rinsing component and the vibration component both provide output kinetic energy through a servo single machine, under the condition that the weight of the cleaning feed liquid in the rinsing barrel is inconsistent, the rinsing barrel is easy to move downwards under the action of the rinsing component and the rinsing barrel is easy to move upwards under the action of the vibration component, and the situation that the rinsing barrel is up-and-down reciprocated and displaced is different is easy to occur, and the arc-shaped inclined plate on the rinsing barrel is easy to prevent the rotating rod from rotating and the bottom wall of the rinsing barrel collides with the swinging plate, so that the rinsing component and the vibration component are easy to collide and damage, and the rinsing action effect and the action efficiency of activated carbon in the rinsing barrel are influenced;
2. after the activated carbon is rinsed, a valve is opened, the rinsing liquid and the activated carbon drop on the first filter screen through a liquid outlet pipe, the activated carbon cannot pass through the first filter screen, and the rinsing liquid passes through the liquid outlet pipe; however, as the rinsing activated carbon is accumulated on the first filter screen, the continuously accumulated activated carbon easily blocks the filter holes of the first filter screen, so that the solid-liquid separation effect of the rinsing liquid and the activated carbon is poor and the efficiency is low;
3. when the activated carbon is dried after being dried by airing on the first filter screen, a blower and an electric heating wire are started, the electric heating wire heats air in the annular air pipe, the blower transmits the hot air to the activated carbon on the first filter screen through a pressurizing nozzle, so that the activated carbon is dried, the hot air can be blown in from all directions, the activated carbon is blown away from the upper surface of the first filter screen, and the activated carbon can be fully dried; but the active carbon that constantly piles up on first filter screen stoving effect is relatively poor, and is located first filter screen upper portion and middle part accumulational active carbon and appear the insufficient condition of stoving easily, and then influence active carbon rinsing and dry continuity production processing effect and machining efficiency.

after the acid liquor is discharged, conveying water liquor into the rinsing cone (1) through a water liquor inlet pipe (6) and a liquor inlet pipe (3), wherein the liquor inlet pipe (3) absorbs the heat source liquor temperature circularly conveyed by a preheating pipe (38) to ensure that the water liquor temperature entering the rinsing cone (1) is not lower than 60 ℃;
step five, repeating the operation of the step two, and rinsing the cone (1) for 3-4 hours;
step six, after the water washing treatment is finished, water enters the inner cavity of the sleeving part (8) from a plurality of overflow holes I (70) formed in the side wall of the liquid discharge cone part (7), and is pumped out and discharged by the water discharge pipe (11);
step seven, opening a gate valve of the discharge pipe (9), enabling the rinsed wet activated carbon material to enter the drying column casing (13) through the discharge pipe (9) and the rotary joint (12), enabling the bottom end of the upper inclined material plate (16) to be positioned above the first discharge port (131), and blocking the first discharge port (131);
step eight, driving a rotating shaft (18) and a drying column casing (13) to rotate through a rotating mechanism, centrifugally dehydrating the wet activated carbon material in the drying column casing (13), discharging water liquid in the drying column casing (13) through a plurality of overflow holes II (130), and falling onto an inclined bottom plate (24) through a plurality of overflow holes III (210) of a lower inclined material plate (21) until discharging from a drain pipe (25);
step nine, in the process of centrifugally separating the wet liquid of the activated carbon, high-temperature gas is conveyed into the drying pipe (14) through the heat source gas inlet pipe (20), the high-temperature gas is sprayed into the wet activated carbon material through the plurality of drying branch pipes (15), and in the process of disturbing the wet activated carbon material through the plurality of drying branch pipes (15), the activated carbon material is quickly heated and dried, and the drying treatment is carried out for 0.2-0.5h;
step ten, after the dry activated carbon material is completed, the telescopic column (17) is driven to move downwards along the support cylinder (19) through the lifting mechanism, the upper inclined material plate (16) is used for removing the blocking discharge opening I (131), the dry activated carbon material slides along the upper inclined material plate (16) and is discharged onto the lower inclined material plate (21) through the discharge opening I (131), and the blocking door (23) at the position of the discharge opening II (22) is opened, so that the dry activated carbon material sliding along the lower inclined material plate (21) is taken out from the support box (26) rapidly.
