Description

Technical Field

[0001] This invention relates to the field of nickel electrode production technology, specifically to a multi-stage purification system for harmful gases during nickel electrode production. Background Technology

[0002] Nickel electrodes are electrodes made of nickel or nickel alloys and are widely used in various electrochemical fields, especially in applications such as batteries, fuel cells, electroplating, and electrolysis. Depending on their application, the design, materials, and manufacturing processes of nickel electrodes vary.

[0003] During the production of nickel electrodes, especially in high-temperature treatment, sintering and electroplating, some harmful gases may be generated. Although the harmful gases in the nickel electrode production process are mainly gaseous pollutants, due to the oxidation reaction on the metal surface during high-temperature smelting, metal oxide particles and other solid pollutants will also be carried out with the airflow. Especially in production environments with high dust concentration, these particulate dust impurities will become one of the sources of pollution.

[0004] The production of nickel electrodes requires multi-stage purification of harmful gases. First, harmful gas dust is removed; second, the gas is purified; then, it is desensitized and denitrified; next, it undergoes catalytic oxidation; and finally, the gas is purified before being discharged. In current technology, bag filters are mostly used to remove harmful gas dust in nickel electrode production. However, the harmful gases generated during the smelting process are at high temperatures, and the filter bags of bag filters are prone to failure when exposed to high temperatures for extended periods. This leads to reduced dust removal efficiency and effectiveness, increases the frequency of filter bag replacement, thereby increasing maintenance costs and production downtime, and ultimately reducing the production efficiency of nickel electrodes.

The two sets of movable blocks 27 move back and forth, thereby driving one set of scrapers 22 to move.

[0056] The working principle of this invention is as follows: When the staff uses this purification system to perform preliminary filtration of harmful gases produced by nickel electrode production, the staff starts the circulation pump, drive motor 19 and air pump 14 inside the coolant circulation tank 5 respectively. Then the harmful gas enters the filter equipment body 1 through the air inlet pipe 2. After the harmful gas passes through the first guide plate 3 and the second guide plate 4, multiple sets of filter bags 13 remove the dust in the harmful gas. Then the harmful gas is discharged from the filter equipment body 1 through the air outlet pipe 17. Next, the gas is purified, then desensitized and denitrified, then catalytically oxidized, and finally the purified gas is discharged.

[0057] The coolant circulation tank 5 guides the coolant into the outlet pipe 6, and then multiple sets of first branch pipes 7 guide the coolant into the two sets of first cooling pipes 8 and two sets of second cooling pipes 9 respectively, so that the temperature of the outer wall of the first guide plate 3 and the second guide plate 4 is reduced. The harmful gas comes into contact with the outer wall of the first guide plate 3 and the second guide plate 4, and the temperature of the harmful gas drops, protecting the multiple sets of filter bags 13. Then the coolant enters the inlet pipe 10 through multiple sets of second branch pipes 11, and then the coolant flows back into the coolant circulation tank 5.

[0058] When harmful gases come into contact with the outer walls of the first guide plate 3 and the second guide plate 4, the high-temperature harmful gases react with the low-temperature outer walls of the first guide plate 3 and the second guide plate 4. As the temperature of the harmful gases decreases, the dust mixed inside the harmful gases adheres to the outer walls of the first guide plate 3 and the second guide plate 4, which improves the separation and removal effect of harmful gases, reduces the workload of the multiple filter bags 13, and extends the service life of the multiple filter bags 13.

[0059] When the drive motor 19 starts, it drives a set of drive shafts 20 to rotate. The two sets of drive shafts 20 are connected by a synchronous belt. The two sets of drive shafts 20 rotate synchronously. The threaded grooves on the outer walls of the two sets of first movable columns 21 are reciprocating threaded grooves. The reciprocating threaded grooves on the outer walls of the two sets of drive shafts 20 are respectively movably connected to the protrusions on the inner walls of the two sets of first movable columns 21. The two sets of first movable columns 21 move back and forth, thereby driving a set of scrapers 22 to move.

[0060] When a set of drive shafts 20 rotates, the set of drive shafts 20 and a set of transmission shafts 23 are connected by a synchronous belt. The set of transmission shafts 23 rotates, and the two sets of transmission shafts 23 are connected by a synchronous belt. The outer walls of the two sets of transmission shafts 23 are provided with reciprocating threaded grooves. The inner wall protrusions of the two sets of second movable columns 24 are respectively movably connected to the reciprocating threaded grooves on the outer walls of the two sets of transmission shafts 23. Therefore, the two sets of second movable columns 24 move back and forth, thereby driving the two sets of scrapers 22 and the diverter plate 25 to move.

[0061] When a set of drive shafts 23 rotates, the set of drive shafts 23 is connected to a set of connecting shafts 26 by a synchronous belt. When the set of connecting shafts 26 rotates, the two sets of connecting shafts 26 are connected by a synchronous belt. When the two sets of connecting shafts 26 rotate, the outer walls of the two sets of connecting shafts 26 are provided with reciprocating thread grooves. The reciprocating thread grooves on the outer walls of the two sets of connecting shafts 26 are respectively movably connected to the protrusions on the inner walls of the two sets of movable blocks 27. The two sets of movable blocks 27 move back and forth, thereby driving a set of scrapers 22 to move.

[0062] When the multiple sets of scrapers 22 move back and forth, they clean the dust adhering to the outer walls of the first guide plate 3 and the second guide plate 4. The cleaned dust falls into the collection box 28, preventing a large amount of dust from adhering to the outer walls of the first guide plate 3 and the second guide plate 4, thus affecting the cooling effect of the first guide plate 3 and the second guide plate 4 on harmful gases. During the movement of the diverter plate 25, the harmful gases are diverted, which improves the contact efficiency between the harmful gases and the first guide plate 3 and the second guide plate 4, thereby improving the cooling effect of the harmful gases and preventing the harmful gases from flowing from the central area of ​​the first guide plate 3 and the second guide plate 4, which would affect the cooling effect of the harmful gases.

[0063] When the air pump 14 is started, the air pump 14 intermittently introduces airflow into the interior of multiple sets of jet pipes 15, and then multiple sets of jet nozzles 16 blow airflow into the interior of multiple sets of filter bags 13, causing the dust adhering to the outer wall of multiple sets of filter bags 13 to fall off, thereby improving the performance of the filter bags 13.
