Abstract
Description
Technical Field
[0001] The utility model relates to a leakage detection device, in particular to a device which can efficiently detect a cloth bag and determine whether the cloth bag is damaged and leaking, and belongs to the technical field of cloth bag damage detection equipment. Background Art
[0002] The bag filter is an important device for filtering dust in the air flow in the metallurgical industry. It can efficiently filter the dust entrained in the target air flow, thereby ensuring the purity of the air flow. In the actual production process, the friction between the dust and the bag causes the bag to wear continuously until a hole appears in the bag. The dust is directly discharged from the hole with the air flow, which not only seriously affects the filtering effect, but also increases the energy consumption of the fan. In addition, the dust from the damaged bag settles in the clean air chamber of the dust collector, contaminating and clogging other bags, thereby reducing the service life of the bag, increasing the difficulty of maintenance, and seriously affecting the overall filtering effect of the bag filter. The bag filter is inspected and repaired regularly, so it is impossible to know in time which bags are damaged and need to be replaced. Inspection and replacement can only be carried out during the inspection. The holes in the damaged bags that cannot be discovered and replaced in time continue to overflow with dust, which greatly reduces the overall filtering effect of the bag filter. Therefore, a leak detection device is needed that can detect the damaged bags in the first time and prompt the staff to replace them in time to ensure the filtering effect of the bag filter.
