Description

Technical Field

[0001] The utility model relates to the technical field of mercury removal from pollutants, and specifically relates to a device for removing mercury from mercury-containing pollutants. Background Technique

[0002] Mercury is a chemical element, commonly known as mercury, which is a transition metal with high density, silver-white color and liquid state at room temperature. Mercury is produced in mines all over the world, mainly from cinnabar. Ingesting or inhaling cinnabar dust is highly toxic. Mercury poisoning can also be caused by contact with mercury soluble in water, inhaling mercury vapor, eating seafood contaminated with mercury or ingesting mercury compounds. When treating mercury-containing pollutants, it is necessary to remove mercury from the pollutants to avoid affecting the environment.

[0003] A patent with the authorized announcement number of "CN214639031U" discloses a device for removing mercury from mercury-containing pollutants, including two support columns. The upper ends of the two support columns are fixedly connected to a housing together. An installation groove is provided on the front side of the housing. An installation column and an installation frame are fixedly connected to the upper end of the housing. This device can first roll the material to a certain extent, making it easier for the material to be analyzed and mercury removed, and then stir it through a stirring blade, avoiding the influence of uneven heating on the effect of analytical mercury removal. The design of the bottom of the installation groove facilitates the staff to quickly export the processed material, improving the processing efficiency.

[0004] However, the following deficiencies exist in this device:

[0005] 1. When the above device is in use, the rolling shell for feeding is always open. When removing mercury from pollutants, the mercury-containing flue gas will directly discharge from the rolling shell and cannot enter the air outlet channel, resulting in the mercury-containing flue gas directly floating into the air and affecting the surrounding environment.

[0006] 2. After the above device treats mercury-containing pollutants, the pollutants will be directly discharged into the storage box for collection, and the pollutants are not compressed, resulting in a large accumulated volume of pollutants, which is not convenient for subsequent cleaning.

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-3, an embodiment provided by the present utility model: a mercury removal device for mercury in mercury-containing pollutants, including a mercury removal bin 1. Legs are provided on both sides of the bottom of the mercury removal bin 1 for supporting the mercury removal bin 1. A sleeve 12 is provided at the top of one side of the mercury removal bin 1. A support rod is provided at one side of the bottom of the sleeve 12 to support the sleeve 12 and improve its stability. A feed hopper 13 is provided at one side of the top of the sleeve 12. A motor B14 is provided on one side of the sleeve 12. The output end of the motor B14 is provided with a screw conveyor 15 that cooperates with the sleeve 12. A rotating rod 11 is provided in the middle of the top of the mercury removal bin 1. The output end of the rotating rod 11 is provided with a motor A10. A stirring member 8 is provided at the bottom of the motor A10. Heaters 7 are provided on both sides inside the mercury removal bin 1. An exhaust pipe 9 is provided at one side of the top of the mercury removal bin 1;

[0025] An activity groove 19 is opened at one side of the top inside the mercury removal bin 1. A guide rod 18 is provided on one side of the inner side of the activity groove 19. A sliding sleeve 20 is sleeved on the outer side of the guide rod 18. A baffle 16 is provided at the bottom of the sliding sleeve 20. A spring 17 is provided on one side of the sliding sleeve 20, and the spring 17 is sleeved on the outer side of the guide rod 18;

[0026] A pressure feed bin 2 is provided in the middle of the bottom of the mercury removal bin 1. A bin door is provided on one side of one end of the pressure feed bin 2 to facilitate taking out the compressed pollutants in the pressure feed bin 2. A connecting pipe 3 communicating with the pressure feed bin 2 is provided in the middle of the bottom inside the mercury removal bin 1. A solenoid valve 5 is provided in the middle of the inner side of the connecting pipe 3. An electric push rod 6 is provided on one side of the pressure feed bin 2. The output end of the electric push rod 6 extends into the pressure feed bin 2 and is provided with a pressing plate 4.

[0027] Furthermore, the stirring member 8 includes a rotating plate and spoiler bars. The rotating plate is provided at the bottom of the motor A10, and multiple groups of spoiler bars are provided at the bottom of the rotating plate. When the motor A10 rotates, it can drive the rotating plate to rotate, and then the rotating plate drives multiple groups of spoiler bars to fully stir the pollutants and ensure uniform heating of the pollutants.

[0028] Furthermore, a sealing plug is provided on one side of the baffle 16, and the shape of the sealing plug is frustum-shaped. When the baffle 16 is clamped into one side of the sleeve 12, the sealing plug can be clamped into the inner side of the sleeve 12 to completely block the sleeve 12 and improve the sealing performance.

[0029] Working principle: When the device is in use, the motor B14 can be started first, and then pollutants are added into the sleeve 12 through the feed hopper 13. At this time, the motor B14 drives the spiral conveyor rod 15 to rotate, conveying the pollutants in the sleeve 12 to one side. When the pollutants reach one side in the sleeve 12, the conveying pressure can push the baffle 16 to move along the guide of the guide rod 18, causing the spring 17 to contract under force and opening one side of the sleeve 12. Then the pollutants can be conveyed into the mercury removal chamber 1 for mercury removal treatment. After the pollutants are added, the elastic force of the spring 17 can be used to push the baffle 16 to reset automatically. At this time, the sealing plug can be stuck into one side of the sleeve 12 to seal the sleeve 12 again, preventing flue gas leakage;

[0030] When mercury removal is carried out, the heater 7 and the rotating rod 11 can be started to operate. The two heaters 7 can heat the pollutants in the mercury removal chamber 1 to precipitate mercury from the pollutants. The rotating rod 11 drives the motor A10 to rotate, and then the motor A10 drives the stirring member 8 to stir the pollutants, making the heating of the pollutants more uniform. After heating to a certain temperature, the mercury-containing flue gas can be discharged through the exhaust pipe 9;

[0031] After the mercury removal of the pollutants is completed, the solenoid valve 5 can be controlled to open the connecting pipe 3. At this time, the pollutants in the mercury removal chamber 1 can fall into the pressure feeding chamber 2 through the connecting pipe 3. Then the electric push rod 6 is started to operate, and the electric push rod 6 can push the pressing plate 4 to move to one side to extrude the pollutants into blocks. Subsequently, the chamber door can be opened to take out the block-shaped pollutants, which is convenient for cleaning and collection.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
