Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device for hot-dip galvanized pipes. Background Technology

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, involves immersing rust-removed steel parts in molten zinc at around 500°C, causing a zinc layer to adhere to the surface of the steel components, thus achieving the purpose of corrosion protection. It is an effective method of metal corrosion protection and is mainly used in metal structural facilities in various industries. However, hot-dip galvanizing generates a large amount of waste gas during the construction process, and direct emission would cause environmental pollution. Therefore, it needs to be treated before being released into the environment.

[0003] Existing technologies, such as Chinese Patent Publication No. CN222540849U, disclose a hot-dip galvanizing furnace for hot-dip galvanizing processing, including a purification mechanism, a pushing mechanism, and an auxiliary mechanism. The pushing mechanism is fixedly installed inside the purification mechanism, and the auxiliary mechanism is fixedly installed on the purification mechanism. The purification mechanism includes a hot-dip galvanizing furnace body, an exhaust pipe, a fan, a treatment box, a discharge pipe, a treatment chamber, and a fixing block. In operation, the waste gas generated during the reaction process in this hot-dip galvanizing furnace body enters the treatment box through the exhaust pipe and fan. The motor-driven fan then pushes the waste gas to the bottom of the treatment box. During this process, the waste gas passes through a filter layer to remove residue, a catalytic layer to remove harmful substances, and an activated carbon purification layer to remove odors, finally being discharged from the exhaust pipe. This design ensures that the waste gas generated during the reaction process of the hot-dip galvanizing furnace body is treated, reducing environmental pollution and improving the environmental performance of the device. However, when the filter layer needs to be cleaned or replaced, the operation of the hot-dip galvanizing furnace needs to be suspended first. Moreover, the filter layer is time-consuming and labor-intensive to install and remove, which affects the processing progress and efficiency.

[0004] To address the issue that cleaning or replacing the exhaust gas treatment device for hot-dip galvanized pipes requires suspending the hot-dip galvanizing operation, which affects processing progress and efficiency, the exhaust gas treatment device needs to be cleaned or replaced after prolonged use. To prevent exhaust gas from escaping, the hot-dip galvanizing operation must be suspended first, and then restarted after cleaning or replacing the treatment device. This significantly impacts processing progress and efficiency, so an improvement is needed. Utility Model Content

After the operation is completed, pull up the pull plate 86 again to push the filter layer 82 into the filter box 6. Then release the pull plate 86, and the insertion rod 85 returns to its original position under the rebound action of the spring 87, and continues to be inserted into the insertion hole 88 to fix the installation plate 83.
