Problems solved by technology
The air leakage rate of the air preheater is an important factor affecting the operating efficiency of the boiler. The main reason is that the traditional hard seal sheet has a large air leakage gap and cannot adapt to the deformation caused by the thermal deformation of the rotor, resulting in an uncontrollable air leakage gap. Only reasonable sealing In order to effectively control the air leakage rate of the air preheater, improve boiler efficiency and reduce energy consumption

The invention discloses a flexible sealing structure display stand of a rotary air pre-heater. The flexible sealing structure display stand of the rotary air pre-heater comprises a shell seat support, a rotor support driving device and a flexible sealing device; the shell seat support is composed of a cabin separating radial frame and axial frames fixedly placed on the ground; a sector plate is fixedly connected with the bottom of the radial frame; a rotor support is arranged in the shell seat support; the rotor support and the shell seat support are provided with a rotary shaft in a coaxial mode; the driving device is connected with the rotary shaft in a transmitted mode and drives the rotor support to rotate around the center; a rotor cabin separating board is arranged on the rotor support in the radial direction; the flexible sealing device is arranged on the cabin separating board; the flexible sealing device is in interference contact with the sector plate. According to the flexible sealing structure display stand of the rotary air pre-heater, an operating mode of the rotary air pre-heater is simulated, the operating state of the internal sealing structure of the rotary air pre-heater can be visually displayed, the advantageous performance of the rotary air pre-heater with the flexible sealing structure is well displayed, the improvement of the air leakage condition is displayed, and the flexible sealing structure display stand is beneficial to product instruction and business negotiation.
Description
technical field [0001] The invention relates to the field of product performance display devices, in particular to a display stand with a flexible sealing structure for a rotary air preheater. Background technique [0002] As the heat exchange equipment of large boilers, rotary air preheater is widely used in power plant boilers. It uses the heat of flue gas discharged from the boiler to preheat the air required for combustion into the boiler, thereby improving the efficiency of the boiler. The air leakage rate of the air preheater is an important factor affecting the operating efficiency of the boiler. The main reason is that the traditional hard seal sheet has a large air leakage gap and cannot adapt to the deformation caused by the thermal deformation of the rotor, resulting in an uncontrollable air leakage gap. Only reasonable sealing In order to effectively control the air leakage rate of the air preheater, improve boiler efficiency and reduce energy consumption. At p...
