Abstract
In order to turn the Bag Filter to the Purse Filter, the past system that the adverse reason is removed, the input of synthetic materiality of dust and air is placed down, and the output is placed up has been improved so that any adverse effect shall not be raised. The form of filteration mechanism is changed from a cylinder from, and the dust and air is mixed to make the entry velocity and one person can velocity of the mixed materiality become lower by the use of infinity, and the reception of filteration mechanism has been made reasonably. The dust separated from the filteration mechanism is desceded down, snd the mixde materiality is ascended up. So, a cross point is formed, and a collision and a friction is occurred from its process, and at its result, dust is scattered to stick to a filter cloth, therefore, the loss of pressure shall ont be appeared by cause of the increase of dust-loading.
