Embodiment
[0070] During the actual operation: during the high-load stage of the desulfurization system, the Unicom baffle 4 is closed, the first absorption tower 5 and the second absorption tower 6 are operated in a unit system, and the oxidation fans of each absorption tower are supplied with air separately, and each absorption tower has at least one oxidation fan. The fan is put into operation, and at least 2 oxidation fans of the two absorption towers are put into operation; taking the oxidation fan A and the oxidation fan C as an example, when the Unicom baffle 4 is closed, the oxidation fan A directly supplies air to the first absorption tower 5, The oxidation blower C supplies air to the second absorption tower 6 .
[0071] During the actual operation: during the low load stage of the desulfurization system, the Unicom baffle 4 is opened, one oxidation fan is stopped, and only one oxidation fan is kept running, and the oxidation air of the oxidation fan is simultaneously supplied t...

The invention relates to a header system energy-saving device and method for a centrifugal desulfurization oxidation fan. The header system energy-saving device for the centrifugal desulfurization oxidation fan comprises a first group of oxidation fans, a second group of oxidation fans, a header, a baffle plate, a first absorption tower and a second absorption tower, wherein the first group of oxidation fans, a second group of oxidation fans, the first absorption tower and the second absorption tower are arranged on the header; the baffle plate is arranged in the header; the first group of oxidation fans is communicated with the first absorption tower through the header; the second group of oxidation fans is communicated with the second absorption tower; when a desulfurization system runs at low load, the baffle plate on the header is opened; and the first group of oxidation fans or the second group of oxidation fans supplies air to the first absorption tower and the second absorption tower. According to the header system energy-saving device and method for the centrifugal desulfurization oxidation fan, the cost of energy-saving transformation is reduced, the supply amount of oxidation air is effectively reduced, and the purposes of saving energy and reducing consumption are achieved.
Description
technical field [0001] The invention relates to the field of flue gas treatment devices, in particular to an energy-saving device and method for a parent tube of a centrifugal desulfurization and oxidation fan. Background technique [0002] At present, with people's emphasis on the environment, new energy has entered an era of rapid development. The country has also given a lot of support to new energy power generation, requiring the power grid to give priority to new energy power generation and increase the market share of new energy power generation. At the same time, higher requirements are put forward for thermal power units, requiring that thermal power units must undergo flexible transformation, and thermal power units must meet the long-term stable operation within the load range of 20%-40%. However, most of the auxiliary equipment of the unit, such as the oxidation fan in the desulfurization system, the slurry circulation pump, etc., are running at a constant speed. ...
