The invention discloses a device for continuously and automatically feeding dust, comprising a dust bed with a cavity, a first dust feeder and a second dust feeder respectively arranged on two sides of the dust bed, a venting pipeline used for introducing gas into the dust bed, and a simulated flue used for accommodating flue gas and connected to the dust bed. When a test starts, starting the first dust feeder, feeding dust to the dust bed while introducing gas into the dust bed, mixing the dust and the gas in the cavity of the dust bed, introducing the mixture into the simulated flue and mixing it with the flue gas. An operator can analyze the flue gas components in the flue. When the dust in the first dust feeder is about to be used up, starting the second dust feeder, and feeding the dust in the second dust feeder to the dust bed. The first dust feeder and the second dust feeder are alternately used and disassembled to ensure continuous and uninterrupted operation of the dust feeding device. According to the device for continuously and automatically feeding dust, the dust feeding speed is guaranteed to be more uniform and controllable, the accuracy of flue gas component analysisis improved, and the dust feeding efficiency is improved.
Description
technical field [0001] The invention relates to the field of test technology, in particular to a continuous automatic ash adding device. Background technique [0002] In order to detect the emission of carbon dioxide, flue gas simulation analysis is required. At present, when the laboratory performs flue gas simulation analysis, it generally adds ash manually, because the speed of manual ash addition is not easy to control, and manual ash addition is prone to intermittent, resulting in uneven ash addition speed and low ash addition efficiency. Low, affecting the accuracy of analysis of smoke components. [0003] Therefore, how to realize continuous and automatic ash addition, not only to ensure the uniformity of ash addition, but also to improve the efficiency of ash addition, and then improve the accuracy of flue gas component analysis is a technical problem urgently needed to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the...
