Description

Technical Field

[0001] This utility model relates to the technical field of acid mist extraction equipment for foil production machines, and in particular to a device that enables online maintenance of the acid mist extraction system. Background Technology

[0002] As an important auxiliary system in copper foil production, the acid mist exhaust system plays a vital role. However, after prolonged operation, current acid mist exhaust systems often experience scaling inside the acid mist scrubbing tower and the formation of copper sulfate crystals inside the inlet and outlet pipes of the acid mist separator. This affects the system's exhaust volume. If the system cannot be shut down (typically, 8-10 copper foil production machines share one acid mist exhaust system), the scaling inside the acid mist scrubbing tower or the accumulated crystals inside the acid mist separator cannot be effectively cleaned. If the crystals are not removed for a long time, they will affect the system's exhaust volume, increase system energy consumption, and even affect the quality of copper foil, posing safety hazards. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses a device that enables online maintenance of an acid mist exhaust system. This utility model stores the acid mist discharged from the main exhaust duct through an acid mist storage mechanism, avoiding the need for workers to stop processing when cleaning or maintaining the acid mist absorption tower or acid mist separator. It also avoids the direct discharge of acid mist without treatment during the cleaning or maintenance of the acid mist absorption tower or acid mist separator, thus preventing air pollution.

[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0005] A device for online maintenance of an acid mist exhaust system includes a main exhaust duct, on which an acid mist separator and an acid mist absorption tower are respectively connected. The main exhaust duct is provided with an air inlet and an air outlet, which are respectively connected to the air outlet and air inlet of an acid mist storage mechanism.

[0006] The acid mist separator is located on one side of the acid mist absorption tower, and also on the side of the air inlet of the main exhaust duct.

[0007] The air inlet and outlet of the main exhaust duct are located on the side of the acid mist separator away from the acid mist absorption tower.

[0008] The main exhaust duct is equipped with a gas shut-off valve, which is located between the acid mist separator and the air inlet and outlet of the main exhaust duct.

[0009] The acid mist storage mechanism includes a storage cylinder, an isolation valve, an air supply pipe, and an exhaust pipe. The air supply pipe and the exhaust pipe are fixedly connected to the air inlet and exhaust port of the storage cylinder, respectively, and the exhaust pipe and the air supply pipe are connected to the air inlet and exhaust port of the main exhaust pipe. An isolation valve is provided on the air supply pipe.

[0010] The exhaust pipe is equipped with a blower, and the top of the storage cylinder is equipped with an air inlet, and an air inlet check valve is fixedly connected inside the air inlet.

[0011] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0012] The present invention provides a device for online maintenance of an acid mist exhaust system. The acid mist discharged from the main exhaust duct is stored through an acid mist storage mechanism, which avoids the need for workers to stop processing when cleaning or maintaining the acid mist absorption tower or acid mist separator. It also avoids the direct discharge of acid mist without treatment during the cleaning or maintenance of the acid mist absorption tower or acid mist separator, thus preventing air pollution.

[0016] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Combined with appendix Figures 1-2 The device for online maintenance of an acid mist exhaust system includes a main exhaust duct 1, which is connected to an acid mist separator 2 and an acid mist absorption tower 3. The main exhaust duct 1 is provided with an air inlet and an air outlet, which are respectively connected to the air outlet and air inlet of an acid mist storage mechanism 4. All electrical equipment in the acid mist storage mechanism 4 is electrically connected to a main control device, and the main control device controls all electrical equipment in the acid mist storage mechanism 4 to operate.

[0018] The acid mist separator 2 is located on one side of the acid mist absorption tower 3, and the acid mist separator 2 is located on one side of the air inlet of the main exhaust pipe 1.

[0019] The air inlet and outlet of the main exhaust duct 1 are located on the side of the acid mist separator 2 away from the acid mist absorption tower 3.

[0020] The main exhaust duct 1 is equipped with a gas shut-off valve, which is located between the acid mist separator 2 and the air inlet and outlet of the main exhaust duct 1. When cleaning or repairing the acid mist separator 2 or the acid mist absorption tower 3, the acid mist is blocked by the gas shut-off valve.

[0021] The acid mist storage mechanism 4 includes a storage cylinder 401, an isolation valve 403, an air supply pipe 404, and an exhaust pipe 406. The air supply pipe 404 and the exhaust pipe 406 are fixedly connected to the air inlet and exhaust port of the storage cylinder 401, respectively. Both the exhaust pipe 406 and the air supply pipe 404 are connected to the air inlet and exhaust port of the main exhaust pipe 1. The air supply pipe 404 is equipped with an isolation valve 403.

[0022] The exhaust pipe 406 is equipped with a blower 405, and the top of the storage cylinder 401 is equipped with an air inlet, and an air inlet one-way valve 402 is fixedly connected inside the air inlet to facilitate the discharge of acid mist in the storage cylinder 401 and prevent acid mist from remaining in the storage cylinder 401 for a long time.

[0023] The aforementioned device for online maintenance of an acid mist extraction system allows for the following steps: When cleaning or maintaining the acid mist separator 2 or acid mist absorption tower 3, the gas shut-off valve on the main exhaust pipe 1 is closed, and the shut-off valve 403 on the gas supply pipe 404 is opened, allowing the acid mist to enter the storage tank 401. This prevents processing from stopping during the cleaning or maintenance of the acid mist separator 2 or acid mist absorption tower 3. After cleaning or maintenance, the shut-off valve 403 is closed, and the gas shut-off valve and the blower 405 are opened to transport the acid mist generated during processing and the acid mist in the storage tank 401 together to the acid mist separator 2 and the acid mist absorption tower 3 for treatment.
