Abstract
The utility model relates to a rotary type preheater rotor which comprises a center assembly, wherein a hot end partition plate, two middle end partition plates and a cold end partition plate are sequentially welded to the center assembly from top to bottom, two ends of each middle end partition plate are respectively in lap joint with the hot end partition plate and the cold end partition plate, and a thermal storage package is arranged between the middle end partition plates. The rotary type preheater rotor has the advantages of eliminating gaps between a relative fixed sealing surface of the rotary type preheater rotor and the rotating rotor, reduces air leakage of the rotary type preheater rotor, reduces the operating cost of the rotary type preheater rotor, and has effects of energy saving and benefit increasing.
Description
Technical field
The utility model relates to a kind of rotary preheater rotor.
Background technology
At present both at home and abroad all can there be temperature difference generation so-called " mushroom " thermal deformation in known rotary preheater rotor because of hot end of rotor and cold junction when hot operation.Successively gap length changes with hot junction and cold junction temperature difference size between rotor rotated and the relatively-stationary sealing surface, and owing to gapped existence, the air of high pressure can bleed in the flue gas of low pressure, causes wind loss, the increase of preheater operating cost.In order to reduce gap between rotor and the sealing surface, be to adopt adjustable sealing surface mode at present, when hot gap changes, the gap variable signal is fed back to executing agency, executing agency's action is adjusted sealing surface up and down according to feedback information, thereby is made the gap reach optimum state.This sealing means complex structure, to the service requirement height, reliability is bad, the maintenance cost height, poor practicability, this method can't solve rotor " mushroom " thermal deformation.No mushroom deformation rotary preheater rotor is from rotor thermal deformation principle, eliminate rotor " mushroom " thermal deformation problem, reduce gap between the hot lower rotor part of preheater and the relatively-stationary sealing surface, reduce preheater and leak out, improve the preheater performance driving economy.
The utility model content
The purpose of this utility model provides a kind of rotary preheater rotor, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of rotary preheater rotor, comprise center element, described center element is welded with hot junction dividing plate, two stage casing dividing plates and cold junction dividing plate from top to bottom successively, and dividing plate two ends, described stage casing are overlapped on respectively on hot junction dividing plate and the cold junction dividing plate, are provided with the accumulation of heat bag between the dividing plate of described stage casing.Hot junction dividing plate and cold junction dividing plate, center element, stage casing dividing plate and accumulation of heat bag are an assembly, and assembly is successively to rotate rotary body during the rotary preheater rotor operation, forms a cylindrical rotor by many groups of such assemblies.There are not temperature difference separately up and down in hot junction dividing plate and cold junction dividing plate during the rotary preheater rotor operation, so hot junction dividing plate and cold junction dividing plate be undirected thermal deformation down all, seal clearance will be effectively controlled, and dividing plate both sides medium can reduce because of the leakage rate that seal clearance produces.
The beneficial effects of the utility model are: eliminated the gap between the relatively-stationary sealing surface of rotary preheater rotor and the rotor rotated, reduced leaking out of rotary preheater rotor.Reduce the operating cost of rotary preheater rotor, had the effect of energy efficiency.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the profile of the described rotary preheater rotor of the utility model embodiment;
Fig. 2 is the left view of Fig. 1.
Among the figure:
1, hot junction dividing plate; 2, cold junction dividing plate; 3, center element; 4, stage casing dividing plate; 5, accumulation of heat bag.
The specific embodiment
Shown in Fig. 1-2, the described a kind of rotary preheater rotor of the utility model embodiment, comprise center element 3, described center element 3 is welded with hot junction dividing plate 1, two stage casing dividing plates 4 and cold junction dividing plate 2 from top to bottom successively, dividing plate 4 two ends, described stage casing are overlapped on respectively on hot junction dividing plate 1 and the cold junction dividing plate 2, and its displacement each other is unrestricted.Be provided with accumulation of heat bag 5 between the described stage casing dividing plate 4.
The utility model relates to a kind of rotary preheater rotor, specifically makes and when using, rotor is welded with center element 3 by hot junction dividing plate 1, stage casing dividing plate 4 and cold junction dividing plate 2, between two stage casing dividing plates 4 accumulation of heat bag 5 is housed.Absorb heat when accumulation of heat bag 5 turns to flue from flue gas, accumulation of heat bag 5 temperature raise, and flue-gas temperature reduces, and accumulation of heat bag 5 forwards air duct to and emits heat then, and air themperature raises, and accumulation of heat bag 5 temperature reduce.Flue gas flow direction from top to bottom, air flow is from descending to making progress, so the temperature of stage casing dividing plate 4 upper ends is higher than the lower end temperature.Stage casing dividing plate 4 is fixed on the center element 3, is the thermal expansion center with center element 3 lower ends, because the effect of temperature difference will produce so-called mushroom deformation up and down.But because hot junction dividing plate 1 is just taken mutually with cold junction dividing plate 2 and stage casing dividing plate 4, both upper and lower displacements are unrestricted mutually, hot junction dividing plate 1 and cold junction dividing plate 2 be undirected thermal deformation down all, rotor does not have mushroom deformation on the whole, rotary preheater rotor seal gap just can be well controlled, and inleakage can reduce.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
