Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of activated carbon desorption device. BACKGROUND

[0002] Activated carbon is a kind of adsorption material widely used in water treatment, air purification, desulfurization and denitrification and other fields. Its adsorption principle is mainly due to the developed pore structure and higher specific surface area of activated carbon, can effectively adsorb and remove various organic and inorganic substances. Activated carbon adsorption process can be divided into physical adsorption and chemical adsorption. Physical adsorption mainly depends on the van der waals force interaction between activated carbon and adsorbed substance, while chemical adsorption is due to the chemical reaction between the chemical functional groups on the surface of activated carbon and the adsorbed substance;The desorption method after activated carbon adsorption mainly has the following several kinds:

[0003] Pyrolysis desorption: by heating activated carbon to high temperature, the adsorbed substance is desorbed from the surface of activated carbon. The principle of pyrolysis desorption is to use heat energy to decompose or sublimate the substance adsorbed on activated carbon, which usually needs to be carried out at a high temperature above 500 DEG C. This method is suitable for stable substances, which can make activated carbon be used repeatedly.

[0004] Steam desorption: steam desorption is to use water vapor to flush activated carbon, increase the relative humidity in activated carbon, weaken the binding force between adsorbed substance and activated carbon, so as to desorb the adsorbed substance. This method is suitable for substances with weak adsorption strength.

[0005] Chemical desorption: under certain conditions, by adding acidic or alkaline solution and reacting with the chemical substances on the surface of activated carbon, so as to desorb. Chemical desorption is suitable for chemical adsorption and ion exchange adsorption.

[0006] Gas desorption: use gas flow to desorb the chemical substances adsorbed on activated carbon, common gases include water vapor, oxygen, air, inert gas, etc.

[0007] Solvent desorption: use specific solvent to contact with activated carbon, and dissolve the adsorbed substance from the surface of activated carbon, common solvents include hot water, concentrated acid, alkali, etc.

[0008] Many existing pyrolysis desorption equipment is used, and it is not convenient to take and place activated carbon, and it cannot be reciprocated. SUMMARY

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] like Figures 1-4 As shown, an activated carbon desorption device is mainly used to desorb used activated carbon, decomposing the substances adhering to the surface of the activated carbon so that the activated carbon can be reused. It includes a storage cabinet 1 for holding the activated carbon. The storage cabinet 1 is a hollow cabinet composed of multiple identical cabinets connected together. The storage cabinet 1 has tiered partitions for holding the activated carbon. An air inlet pipe 2 is installed at the top of the storage cabinet 1; an air outlet pipe 3 is installed at the rear of the storage cabinet 1; one end of the air inlet pipe 2 is connected to the storage cabinet 1, and the other end is connected to a fan 6; one end of the air outlet pipe 3 is connected to the storage cabinet 1, and the other end is connected to a heat recovery device 7.

[0029] The air inlet pipe 2 is located vertically above the placement cabinet 1, and multiple connecting pipes (not labeled) are respectively installed between the air inlet pipe 2 and the placement cabinet 1.

[0030] The connecting pipe is vertically installed between the air inlet pipe 2 and the placement cabinet 1, and is installed according to the cabinet body; specifically, each cabinet body is provided with a connecting pipe to connect the inside of the cabinet body with the air inlet pipe 2. In this way, when the fan 6 is operating, hot air can enter each cabinet body through the air inlet pipe 2, and the hot air will work on the activated carbon, so that the pollutants adsorbed on its surface can be decomposed.

[0031] The exhaust pipe 3 is located on the rear side of the placement cabinet 1, near the bottom of the placement cabinet 1. Multiple connecting pipes a (not labeled) are provided between the exhaust pipe 3 and the placement cabinet 1. Specifically, the connecting pipes a are provided on each corresponding cabinet, just like the connecting pipes, so that the cabinet and the exhaust pipe 3 are interconnected. The connecting pipes a are also vertically arranged, just like the connecting pipes. After the air inlet pipe 2 heats the placement cabinet 1, the substances on the activated carbon are decomposed to form waste gas. The hot air generated by the fan 6 blows in from the top, causing the waste gas to be blown out from the exhaust pipe 3 at the bottom and into the heat recovery device 7 connected to the exhaust pipe 3.

[0032] The heat recovery device 7 is connected to a burner 5. Specifically, the burner 5 is equipped with a catalyst. The specific type of catalyst can be used according to the activated carbon situation of different customers. Since the applicant does not produce catalysts and this application mainly improves the equipment, the applicant does not describe the catalyst formula in detail. It should be noted that the burner 5 used in this application is existing equipment and has not been improved. Therefore, the applicant does not describe the burner 5 in detail.

[0033] The burner 5 is connected to a burner control device 4 for controlling the burner to operate.

[0034] The heat recovery device 7 is connected to the fan 6, so that the heat in the heat recovery device 7 can be reused. The hot air generated by the fan 6 enters the air inlet pipe 2 again to thermally decompose the activated carbon. Then, the waste gas enters the air outlet pipe 3. After heat recovery by the heat recovery device 7, the waste gas enters the burner 5 to carry out a catalytic reaction, turning the waste gas into carbon dioxide and water vapor.

[0035] The placement box 1 contains two identical activated carbon racks arranged side by side.

[0036] The activated carbon storage rack includes a rotating shaft 1.3 and a turntable 1.1 evenly arranged vertically on the rotating shaft 1.3. A detachable placement block 1.2 is provided above the turntable 1.1. Specifically, the device of this application is mainly used for honeycomb activated carbon, with a size generally within 100*100*100mm. Traditionally, the placement area is on a partition, which is inconvenient to put in and take out. The turntable designed in this application can be rotated during placement, making it more convenient to place activated carbon. Furthermore, the turntable is equipped with a detachable placement block, which can be replaced according to different sizes of activated carbon. This makes it easier to fix the activated carbon after placing it on the appropriate placement block 1.2.

[0037] The process is repeated until there is no more exhaust gas in burner 5, at which point the desorption of activated carbon in the cabinet is complete.

[0038] The beneficial effects of this utility model are:

[0039] By interconnecting the air inlet pipe, air outlet pipe, burner, fan, and heat recovery box, the desorption device of this application forms a closed loop, which can better utilize heat recovery, reduce some costs, and is more conducive to temperature maintenance; and the rotating rack makes it easier to take out activated carbon.
