Abstract
The utility model relates to a flexible sealing device of a rotary air preheater, which is characterized in that the flexible sealing device consists of a connection plate, a splint and a metal wire layer, the rear end of the metal wire layer is splinted and welded between the front end of the connection plate and the splint, the front end of the metal wire layer is the front end of the flexible sealing device, and an installation hole is arranged on the connection plate. The flexible sealing device is installed on the beam of the rotary drum of the rotary air preheater through the installation hole on the connection plate or is installed on the beam of the rotary drum of the rotary air preheated jointly with a sealing strip. The utility model has the advantages that the brush hair is notapt to fall off, the structure is simple, the design is reasonable, the manufacturing is precise, the comprehensive cost is low, the installation is convenient, the sealing effect is good, the servicelife is long and the like.
Description
Technical field
The utility model relates to the sealing device of a kind of rotary regenerative air preheater, particularly this preheater, belongs to utilize the passage that rotatablely moves to carry out the parts of the equipment of heat exchange.
Background technology
In present domestic large-scale rotation air preheater structure, inner its is sealed into lamellar seal, and its structure is for being provided with radially around rotor rotated, axially and the hoop sealing pair, and seal is adjustable diaphragm seal, and diaphragm seal is fastened on the revolvable beam.Air preheater is divided into air side and fume side, has big pressure reduction between the two, because its diaphragm seal has certain design gaps, and the problem that causes air to be revealed, the said exactly problem of leaking out to flue gas.Normal air leak rate of air curtain design load is about 9%; because diaphragm seal is the rigidity sealing device, though can the adjusting play, can only when installing or shut down, adjust; can not when work, adjust; bump mill in order to prevent, the gap of Tiao Zhenging is bigger when mounted, and the rotating cylinder of air preheater also can vary with temperature the irregular protuberance of generation in work; cause the gap further to be strengthened; it is a lot of to make actual air leak rate of air curtain exceed design load, up to 20%～30%, obviously increases energy consumption and operation cost.
Summary of the invention
The purpose of this utility model is to make the too big weak point of leakage rate in order to overcome above-mentioned existing lamellar seal greatly because of its gap, providing a kind of can replace diaphragm seal or be installed in simple and reasonable on the beam of rotating cylinder jointly with diaphragm seal, good seal performance, leakage rate is little, helps the flexible seal device energy-conservation and rotary regenerative air preheater that cuts operating costs.
The flexible seal device of rotary regenerative air preheater of the present utility model, this flexible seal device comprises gusset piece, clamping plate and metal wire layer, wherein, the rear end of metal wire layer clamps and is welded between gusset piece front end and the clamping plate, the front end of metal wire layer is the front end of flexible seal device, and gusset piece is provided with installing hole.This flexible seal device is installed in through the installing hole on the gusset piece on the beam of rotating cylinder of rotary regenerative air preheater, or is installed in jointly on the beam of rotating cylinder of rotary regenerative air preheater with diaphragm seal.For the ease of installing and helping rotating, the front end of gusset piece can suitably bend towards metal wire layer.The metal wire layer of described flexible seal device is made up of resistant to elevated temperatures filament.
Flexible seal device of the present utility model, because will radially, the leaf seal of the rigidity in the axial and hoop sealing pair sets up or changes into the flexible seal device of metal wire layer, the metal wire layer of forming by resistant to elevated temperatures filament, it is flexible and rigidity is moderate, even rotating cylinder is gone up in contact, does not also influence the normal operation of air preheater, because of metal wire layer has suitable thickness, and both sides pressure reduction is less, and its sealing and good leak-proof effect are added the sealing advantage of bristle and fanning strip zero clearance.Can effectively stop medium (medium that must seal) to leak outside, can prevent that again the medium of exterior ambient environment from entering sealed chamber's (interior leakage).Leakage rate only is 1/5～1/20 of the design leakage rate of general expression sealing.Again because of seal is the integral solder structure, the bristle difficult drop-off has simple in structurely, reasonable in design, makes precisely, and integrated cost is low, and is easy for installation, advantages such as good sealing effect and long service life.
