Problems solved by technology

[0005] (2) The P-shaped sheet is often damaged and fails to operate in a tension, corrosion, and friction environment for a long time, and its sealing gap is more difficult to guarantee
[0006] (3) The air volume of the sealing fan selection is too large (the calculation gap is at least 0.3mm), and because the actual gap is usually difficult to guarantee, the sealing air volume introduced into the cavity is far from enough when the gap expands, resulting in the failure of the sealing effect ...

Embodiment Construction

[0041] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a louver baffle door with a sealing device includes a door frame 1 and a baffle 3 installed on the door frame 1 through a rotating shaft. The baffle 3 can be set in one or more pieces as required. In this embodiment, two The baffle 3 will be described as an example.

[0042] The door frame 1 is composed of a rectangular frame and connecting bars located in the middle of the rectangular frame connecting opposite sides. Two baffles 3 are fixedly installed on the inner side of the door frame 1 through the rotating shaft (the main shaft 9 and the slave shaft 6). The electric actuator 8 is installed on the side of the door frame 1. On one side, the door frame 1 on the other side opposite to the installation of the electric actuator 8 is provided with a second air duct 11 with a built-in butterfly valve, and the top of the door frame 1 near the side where the electric actuator 8 is installed is provid...

Abstract

The invention discloses a shutter baffle door provided with a sealing device and belongs to the field of smoke gas treatment devices. The shutter baffle door comprises a door frame, at least one rotating shaft arranged on the door frame, and a baffle driven by the rotating shaft, wherein the inner edge of the door frame is wound with a flexible sealing piece; a cavity is defined between the flexible sealing piece and the inner edge of the door frame; the door frame is provided with a first air pipe communicated with the cavity; an open slot matched with the flexible sealing piece is arranged around the outer edge of the baffle; the door frame is provided with a second air pipe running through the flexible sealing piece and communicated with the open slot, and the second air pipe is tightly matched with the flexible sealing piece. The shutter baffle door is used in an air inlet flue, an air outlet flue and a bypass flue in a flue gas desulfurization device, and is good in sealing effect, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of flue gas treatment equipment, in particular to a louver baffle door with a sealing device. Background technique [0002] At present, the uniaxial double louvered baffle door usually adopts a P-shaped shrapnel sealing structure or an overlapping shrapnel sealing structure. Internal seals on louvered flapper doors for gas partitions. According to the technical solution provided by the utility model, a number of rotatable blades are installed in the door frame, and a rotating shaft is arranged at both ends of each blade. Elastic seal, the fixed end of the elastic seal is installed on both longitudinal sides of the blade, the movable end of the seal extends outward along the plane of the blade for a certain length, when two adjacent blades are in a closed state, one of the blades The movable end of the elastic sealing sheet rides on another blade. The device is installed around the blades of the louver and at both e...
