In the process of copper pipe manufacturing, zinc oxide is generated along with the production of copper, and if a large amount of zinc oxide dust is not treated, it will lead to flying in the sky. Therefore, the dust removal system must be introduced as the most mature dust removal system at present. The core of the system, bag filter is naturally indispensable.
In the process of producing copper pipes, first the copper is melted, then the molten copper water is poured into the holding furnace, and finally the copper bars are pulled out of the holding furnace. In the process, the copper water is melted and poured out. There is a lot of smoke and dust generated when the package is dumped. How to handle the dust removal and purification at these three points becomes the key to designing the dust removal system under this scenario. We can consider using a large centralized bag before designing. The precipitator, the choice of bag filter, because the bag filter has developed relatively mature, because in this scene, there will be three places where the smoke will be generated, it should design the suction outlet in these three places, First of all, it is possible to design the rotary receiving cover at the bottom of the package, so that the dust can be recovered without hindering the experiment of the wheel turning and the workers at the side of the furnace. An annular suction cover can be added at the outlet of the copper water, which can effectively control When the copper water melts and pours out, the smoke system can also install a rotary joint with a rotating shaft of the tilting furnace on the reventilation pipe to ensure that the annular suction hood can also rotate when the tilting furnace rotates. Turn around to ensure the efficiency of dust collection while increasing the flexibility of the dust removal system.
The use of such a design can effectively prevent the smoke and dust pollution in the copper tube manufacturing process. However, when designing the system, it is also necessary to consider a necessary practical factor, that is, the temperature of the soot, and the general bag filter is using the filter belt. When the dust is removed, the temperature of the filter bag is temperature-resistant, and the temperature of the soot when the copper pipe is manufactured reaches 1200 degrees. If the filter material of the bag filter is not carefully selected, high-temperature smoke burns the bag easily. The situation, but currently widely used high heat-resistant filter material, PTFE or stainless steel fiber, the heat-resistant temperature is far below 1200 degrees, which requires the installation of flue gas cooling device before the bag filter. If the temperature drops, you can also use the method of lengthening the dust collection pipe to cool naturally. If you use the latter, you need to set the temperature control device before the bag filter contacts the smoke. Once the smoke dust exceeds the pre-warning temperature of the bag filter, Stop the entire system immediately.
