Embodiment 1
[0021] refer to Figure 1-Figure 3 , the embodiment of the present invention provides a blast furnace blast dehumidifier with automatic cleaning function. The dehumidifier includes a casing 1 , a main air duct 2 , a bypass air duct 3 and a heat exchange mechanism 4 . The main air duct 2 is arranged in the middle of the casing 1 and penetrates through the front and rear side walls of the casing 1 . The middle of the main air duct 2 is provided with a first damper 5 along its cross section, and the rear end of the main air duct 2 is communicated with the blower. When the dehumidification function is not used, when the first damper 5 is opened, the air is directly sucked into the blast furnace from the main air duct 2 by the blower.
[0022] The bypass air duct 3 is arranged in the casing 1 on both sides of the main air duct 2 , and a heat exchange mechanism 4 is arranged in the bypass air duct 3 . Specifically, the heat exchange mechanism 4 is a fin heat exchanger, which incl...

The invention relates to the technical field of blast-furnace blast dehumidification, in particular to a blast-furnace blast dehumidifier with an automatic cleaning function. Comprising a shell, a main air duct, a bypass air duct and a heat exchange mechanism. The main air duct is arranged in the middle in the shell, the bypass air ducts are arranged in the shell on the two sides of the main air duct, and the heat exchange mechanisms are arranged in the bypass air ducts; a first air door is arranged in the middle of the main air duct; a second air door and a third air door are arranged on the side wall, connected with the bypass air duct, of the main air duct and are arranged on the front side and the rear side of the first air door correspondingly. A fourth air door is arranged on the side wall, connected with the shell, of the bypass air duct; and a fan is arranged at the rear end of the heat exchange mechanism in the bypass air duct. In the using process, self-cleaning can be achieved, and the effects of improving the heat exchange efficiency of the heat exchanger and recovering the original design efficiency of the dehumidifier are achieved. The dehumidification efficiency of the dehumidifier can not be reduced for a long time, and the service life of the dehumidifier is greatly prolonged.
Description
technical field [0001] The invention relates to the technical field of blast furnace blast dehumidification, in particular to a blast furnace blast dehumidifier with automatic cleaning function. Background technique [0002] Most of the existing blast furnace blast dehumidifiers are condensing type, which have the characteristics of wide application range and low maintenance cost after use. However, since most of its use environments are near metal smelting blast furnaces with a lot of dust and debris, the efficiency drops significantly after two years of use. The main reason is that these dusts and sundries will be sucked into the dehumidifier with the work of the blower, and will adhere to the surface of the heat exchanger inside the dehumidifier in large quantities, which will seriously affect the heat exchange efficiency after reaching a certain level. Since the structure of the large dehumidifier is a fixed heat exchanger, the heat exchanger cannot be removed and clean...
