Embodiment Construction
[0026] The present invention is described in detail below in conjunction with accompanying drawing:
[0027] A wind hood rotary denitrification reactor, such as figure 1 As shown, it includes the reducing gas inlet 1-1 and the flue gas inlet 3-1, the body 4, the rotating shaft 5, the flue gas outlet 3-2 and the reducing gas outlet 1-2, wherein the reducing gas inlet 1-1, the reducing gas outlet 1 -2 are equipped with flue gas flue sealing ring 7.
[0028] During the test, the reducing gas flow rate is 0.1-100m / s, the flue gas temperature is 80-400°C, and the reducing gas temperature is 150-500°C. The body of the denitrification device is cylindrical, with a rotating shaft inside. There are several zones in between, and each zone can be loaded with catalyst. The reducing gas inlet flue and the reducing gas outlet flue are driven by an external transmission mechanism to rotate, and drive the inlet and outlet windshields connected to them to rotate synchronously. The upper and ...

Abstract
The invention discloses a wind cover type partition rotary denitrification reactor, comprising a reactor body; the reactor body has a ring-shaped structure, and a ring-shaped area of the ring-shaped structure is divided into a plurality of fan-shaped reaction zones along the circumferential direction of the reactor body; each fan-shaped reaction zone is internally filled with a catalyst used for a reaction of smoke and reducing gas; an upper wind cover and a lower wind cover are respectively arranged at the upper part and the lower part of the reactor body; the center of the upper wind cover is connected with the center of the lower wind cover by a rotating shaft passing through the center of the reactor body; the center of the upper wind cover is connected with a reducing gas inlet channel, and the center of the lower wind cover is connected with a reducing gas outlet channel; the reducing gas inlet channel, the reducing gas outlet channel, the upper wind cover and the lower wind cover are driven to rotate along the central axis of the reactor body by the rotating shaft; the upper wind cover and the lower wind cover block part of the reaction zones of the reactor body; the upper parts of the reaction zones, which are not blocked by the upper wind cover and the lower wind cover, are connected with a smoke inlet reaction channel, and the lower parts of the reaction zones, which are not blocked by the upper wind cover and the lower wind cover, are connected with a smoke outlet reaction channel.
Description
technical field [0001] The invention belongs to the field of flue gas denitrification, and relates to a fan-hood type partitioned rotary denitrification reactor. Background technique [0002] With the development of my country's economy and the improvement of people's living requirements, the pressure brought by environmental pollution is increasing day by day. As one of the main pollutants of current air pollution, nitrogen oxides are closely related to the quality of my country's atmospheric environment. At present, the main method of industrial denitrification is NH 3 -SCR, but this method exposes many disadvantages. CO-SCR, HC-SCR and H 2 -SCR has attracted people's attention because of its advantages of less secondary pollution and high denitrification efficiency. [0003] Rotary semi-fluidized denitrification is an effective method, but the catalyst rotates with the device, which can easily cause turbulence of the catalyst, affect the denitrification efficiency, blo...
