Description

Technical Field

[0001] This utility model belongs to the field of chemical technology, and in particular relates to a device for treating fugitive ammonia gas produced by electrolysis. Background Technology

[0002] During the electrolysis of manganese in an electrolysis workshop, waste gas (ammonia) is generated and enters the workshop. Currently, the common practice is to install multiple high-power industrial exhaust fans to enhance air convection and dissipate the ammonia gas without proper ventilation. However, since the ammonia gas emissions from electrolysis workshops are primarily fugitive, the odor produced by the released ammonia gas has a significant impact on the surrounding environment. Therefore, there is an urgent need for those skilled in the art to propose a device for the fugitive emission control of electrolytic ammonia gas in electrolysis workshops. Utility Model Content

[0003] In view of this, the present invention provides an electrolytic ammonia gas fugitive gas treatment device to solve the above problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electrolytic ammonia gas fugitive treatment device includes: a gas collection hood, a duct, a fan, and an ammonia absorption tower. The electrolytic cell is located inside the electrolysis workshop. The gas collection hood is installed at the top of the electrolysis workshop and is connected to the interior of the electrolysis workshop. The gas collection hood is connected to one end of the duct, and the other end of the duct is connected to the fan. The fan is connected to the ammonia absorption tower, and an exhaust pipe is provided at the top of the ammonia absorption tower.

[0006] Furthermore, multiple gas collection hoods are provided, all of which are installed at the top of the electrolysis workshop and connected to the interior of the electrolysis workshop, and all of which are connected to the air duct.

[0007] Furthermore, a ventilation opening is provided at the bottom of the electrolysis workshop, and the ventilation opening is located around the electrolytic cell.

[0008] Furthermore, it also includes a spraying device and a water tank. The spraying device includes spray heads installed inside the ammonia absorption tower, located below the exhaust pipe. The water tank is located at the bottom of the ammonia absorption tower, and the ammonia absorption tower is connected to the water tank.

[0009] Furthermore, the spraying device also includes a circulating water pump and a spray pipe. The circulating water pump is connected to the water tank, and one end of the spray pipe is connected to the circulating water pump, while the other end is connected to the spray head.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention features a gas collection hood installed at the top of the electrolysis workshop. A fan collects fugitive ammonia gas from the workshop and sends it to an ammonia absorption tower. The ammonia gas is then sprayed with water to generate ammonia water, which is collected in a water tank. A circulating water pump is used to achieve the cyclical absorption of fugitive ammonia gas, reducing the amount of ammonia water used in the production process and significantly reducing fugitive ammonia emissions, thus having a positive impact on the surrounding environment. The treated ammonia water is reused in the production system. Ventilation openings at the bottom of both sides of the electrolysis workshop increase gas flow, facilitating the collection of fugitive ammonia gas within the workshop. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See attached document Figure 1 As shown, this utility model provides a device for treating fugitive ammonia gas from electrolysis, comprising: a gas collecting hood 1, a duct 2, a fan 3, and an ammonia absorption tower 4. An electrolytic cell 5 is installed inside an electrolysis workshop 6. The gas collecting hood 1 is installed at the top of the electrolysis workshop 6 and communicates with the interior of the workshop 6. One end of the gas collecting hood 1 is connected to the duct 2, and the other end of the duct 2 is connected to the fan 3. The fan 3 is connected to the ammonia absorption tower 4, and an exhaust pipe 7 is installed at the top of the ammonia absorption tower 4. The side walls of the electrolysis workshop 6 are sealed with translucent panels, and ventilation openings 8 are provided at the bottom. The ventilation openings 8 are located around the electrolytic cell 5, increasing gas flow and facilitating the collection of fugitive ammonia gas within the electrolysis workshop 6 by the fan 3.

[0018] An electrolytic ammonia fugitive gas treatment device further includes a spraying device and a water tank 9. The spraying device includes spray heads 10, which are installed inside the ammonia absorption tower 4, below the exhaust pipe 7. The water tank 9 is located at the bottom of the ammonia absorption tower 4, and the ammonia absorption tower 4 is connected to the water tank 9. The spraying device also includes a circulating water pump 11 and a spray pipe 12. The circulating water pump 11 is connected to the water tank 9, and one end of the spray pipe 12 is connected to the circulating water pump 11, and the other end is connected to the spray head 10.

[0019] In one optional embodiment, multiple gas collection hoods 1 are provided, and the multiple gas collection hoods 1 are all installed at the top of the electrolysis workshop 6 and communicate with the interior of the electrolysis workshop 6. The multiple gas collection hoods 1 are all connected to the air duct 2.

[0020] Working principle: Ammonia gas produced by electrolysis of manganese in electrolytic cell 5 enters electrolysis workshop 6, becoming fugitive ammonia gas. Since ammonia gas is less dense than air, it moves upward and gathers at the gas collection hood 1 at the top of electrolysis workshop 6. The collection efficiency of fugitive ammonia gas is improved by the action of fan 3. The ventilation opening 8 at the bottom of electrolysis workshop 6 increases the gas flow effect, further improving the collection efficiency of fugitive ammonia gas. The fugitive ammonia gas enters the air duct 2 from the gas collection hood 1, and then enters the ammonia absorption tower 4 through fan 3. The ammonia gas is sprayed with water to generate ammonia water, which is then collected in water tank 9. The circulating water pump 11 is used to realize the circulation absorption of fugitive ammonia gas, reducing the amount of ammonia water used in the production process, greatly reducing the fugitive emission of ammonia gas, which is beneficial to the surrounding environment. The ammonia water generated is recycled for use in the production system.
