Description

Technical Field

[0001] This utility model belongs to the field of activated carbon dust removal technology, and specifically relates to a dust removal device for a carbon mixing system. Background Technology

[0002] Activated carbon, with its powerful adsorption capacity, is widely used in production processes such as impurity removal, deodorization, and decolorization. However, in actual production, the dust generated during the preparation of activated carbon slurry has been a persistent problem for various enterprises, prompting them to devise various solutions. The most common method is to use wet activated carbon (wet carbon) when directly adding it to solve the dust problem. However, purchasing wet carbon from activated carbon manufacturers is inconvenient for transportation and storage, and the quality of the activated carbon is difficult to control. For example, patent number CN202122570734 discloses a dust-free activated carbon collection device that uses an induced draft fan to create a slight negative pressure inside the carbon mixing tank, thereby introducing air containing activated carbon particles into a bag filter for dust removal. However, this device fails to consider that the diameter of activated carbon particles is very small, easily penetrating the filter bags of the bag filter. Furthermore, the carbon mixing tank contains a certain amount of water vapor. When air carrying water vapor and activated carbon particles is introduced onto the surface of the filter bags, it easily causes blockage of the bag filter, affecting the dust removal effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a dust removal device for a carbon mixing system, which solves the dust problem caused by direct addition of activated carbon during the carbon slurry mixing process.

[0004] This utility model is implemented as follows: a dust removal device for a carbon mixing system is provided. The carbon mixing system includes a carbon mixing tank, on which a carbon inlet and a dust outlet are respectively provided. The dust removal device includes an induced draft fan, a water curtain dust collector, a vacuum drum filter, a process water storage tank, a centrifugal pump, and a vacuum pump. The air inlet of the water curtain dust collector is connected to the dust outlet through a dust discharge pipe. The induced draft fan is installed on the dust discharge pipe. A spray device is installed inside the water curtain dust collector. The liquid outlet of the water curtain dust collector is connected to the liquid inlet of the vacuum drum filter through a liquid discharge pipe. The liquid outlet of the vacuum drum filter is connected to the inlet of the process water storage tank through a liquid outlet pipe. The outlet of the process water storage tank is connected to the spray device through a water pipe. The centrifugal pump is installed on the water pipe. An exhaust pipe is installed at the air outlet of the process water storage tank. The vacuum pump is installed on the exhaust pipe.

[0005] Furthermore, the vacuum drum filter is also equipped with a water inlet and a level gauge, a water inlet pipe is connected to the water inlet, and a water inlet valve is installed on the water inlet pipe. The signal of the level gauge is interlocked with the opening angle of the water inlet valve.

[0006] Furthermore, a pressure gauge is also installed on the carbon mixing tank, and the signal of the pressure gauge is interlocked with the pressure of the induced draft fan.

[0007] Furthermore, the filter material inside the vacuum drum filter is diatomaceous earth.

[0008] Furthermore, a slag outlet is provided on the vacuum drum filter, and the slag outlet is connected to the feed end of the auger through a slag discharge pipe.

[0009] Compared with existing technologies, the dust removal device of the carbon mixing system of this utility model includes a carbon mixing tank and a dust removal device including an induced draft fan, a water curtain dust collector, a vacuum drum filter, a process water storage tank, a centrifugal pump, and a vacuum pump. Air containing activated carbon particles in the carbon mixing tank is drawn into the water curtain dust collector by the induced draft fan, where it is adsorbed by the liquid of the spray device, resulting in a liquid mixture containing activated carbon. This mixture then enters the vacuum drum filter for filtration. The resulting liquid is pumped back to the spray device by the centrifugal pump for reuse in dust removal. This utility model uses a water curtain dust collector to remove activated carbon powder from the air. The resulting aqueous solution is introduced into the vacuum drum filter, where the activated carbon powder is adsorbed onto the drum surface. Cooling water flows into the drum and is stored in the process water storage tank. The filtered water is then pumped back into the water curtain dust collector by the centrifugal pump for dust removal and reuse. Attached Figure Description

[0013] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] Please refer to Figure 1 As shown in the preferred embodiment of the dust removal device of the carbon mixing system of this utility model, the carbon mixing system includes a carbon mixing tank 1, and the dust removal device includes an induced draft fan 2, a water curtain dust collector 3, a vacuum drum filter 4, a process water storage tank 5, a centrifugal pump 6, an auger 7, and a vacuum pump 8.

[0015] A carbon inlet 11 and a dust outlet 12 are provided on the carbon mixing tank 1. Activated carbon enters the carbon mixing tank 1 through the carbon inlet 11 and is mixed, while the dust generated during the mixing of activated carbon in the carbon mixing tank 1 is discharged through the dust outlet 12.

[0016] The air inlet 31 of the water curtain dust collector 3 is connected to the dust outlet 12 via the dust outlet pipe 91, and the induced draft fan 2 is installed on the dust outlet pipe 91. A spray device 32 is installed inside the water curtain dust collector 3, and the liquid outlet 33 of the water curtain dust collector 3 is connected to the liquid inlet 41 of the vacuum drum filter 4 via the liquid outlet pipe 92. The spray device 32 adsorbs activated carbon particles within the water curtain dust collector 3, achieving a dust removal effect, and finally obtaining a liquid mixture containing activated carbon. This liquid mixture enters the vacuum drum filter 4 for filtration.

[0017] The outlet 42 of the vacuum drum filter 4 is connected to the inlet 51 of the process water storage tank 5 via the outlet pipe 93. The outlet 52 of the process water storage tank 5 is connected to the spray device 31 via the water pipe 94. A centrifugal pump 6 is installed on the water pipe 94. The liquid obtained after filtration by the vacuum drum filter 4 enters the process water storage tank 5 through the outlet 42 and the outlet pipe 93 and is collected and stored. The liquid temporarily stored in the process water storage tank 5 is pressurized by the centrifugal pump 6 and then enters the spray device 31 through the water pipe 94 to adsorb activated carbon dust in the water curtain dust collector 3 for reuse.

[0018] An exhaust pipe 95 is installed at the air outlet 53 of the process water storage tank 5, and a vacuum pump 8 is installed on the exhaust pipe 95. The vacuum pump 8 is set to adjust the vacuum level in the vacuum drum filter 4 to -0.02~-0.08MPa. Its main function is to adjust the vacuum level in the drum cavity of the vacuum drum filter 4 to achieve the vacuum level required by the process.

[0019] The vacuum drum filter 4 is also equipped with a water inlet 43 and a level gauge 45. A water inlet pipe 96 is connected to the water inlet 43, and a water inlet valve 44 is installed on the water inlet pipe 96. The signal from the level gauge 45 is interlocked with the opening angle of the water inlet valve 44. When the liquid level in the vacuum drum filter 4 is lower than 30%, the water inlet valve 44 is opened to automatically replenish water and adjust the liquid level. Because the wet carbon waste will carry away some water during the operation of the vacuum drum filter 4, the vacuum drum filter 4 is interlocked with a liquid level system. When the water level is lower than the set value, the water inlet valve 44 is opened to automatically replenish water to prevent affecting the dust removal effect of the water curtain dust collector 3.

[0020] A pressure gauge 13 is also installed on the carbon mixing tank 1, and the signal from the pressure gauge 13 is interlocked with the pressure of the induced draft fan 2. The pressure in the carbon mixing tank 1 is controlled at a slightly negative pressure, approximately -0.5 to -0.1 kPa. Its main function is to introduce the air containing activated carbon particles and a certain amount of water vapor from the carbon mixing tank 1 into the water curtain dust collector 3.

[0021] The filter material inside the vacuum drum filter 4 is diatomaceous earth. During the filtration process of the vacuum drum filter 4, the diatomaceous earth adsorbs the activated carbon in the liquid mixture containing activated carbon.

[0022] The vacuum drum filter 4 is also provided with a slag outlet 46, which is connected to the feed end 71 of the screw conveyor 7 through a slag discharge pipe 97. The carbon slag in the screw conveyor 7 falls into the vehicle 10 below it for collecting carbon slag through the discharge end 72.

[0023] This utility model mainly applies to the dust removal treatment of water-insoluble dust. Dust can be settled using a water curtain dust collector, and then removed by a vacuum drum filter. Water-soluble dust can be directly removed using the water curtain dust collector.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
