Description
Technical field
This utility model relates to a kind of heat exchanger structure, particularly relates to a kind of easy accessibility, good airproof performance, the heat exchanger tube location structure of fixing reliable top board.
Background technology
nullCommonly used swinging GGH in existing sulfur removal technology，But it is high generally to there is cost in this type of heat exchanger，Energy consumption is big，The shortcomings such as air leak rate of air curtain is high，And tubular type GGH is high owing to having heat transfer efficiency，Low power consumption and other advantages，The most day by day it is generalizable，Tubular type gas-gas heat exchanger (GGH) is a kind of heat transmission equipment utilizing high temperature fluid waste-heat cryogen，It is mainly made up of housing and some heat exchanger tubes，Its Central Plains exhaust gases passes is heat exchanger tube，Heat exchanger tube space outerpace is neat stress passage，Keep between heat exchanger tube and housing tube sheet being tightly connected，Due to the heat exchanger tube in structure, to have heat-transfer capability strong，Heat transfer efficiency is high，The feature that thermal coefficient of expansion is big，Therefore stress rupture is produced easily and between housing tube sheet when heat exchanger tube expanded by heating，Also it is highly vulnerable to breakage the sealing between housing tube sheet and heat exchanger tube simultaneously，Reduce service life and the security reliability of heat exchanger.
Summary of the invention
This utility model mainly provides a kind of easy accessibility, good airproof performance, the heat exchanger tube location structure of safe and reliable top board, solve heat exchanger tube junction sealing present in prior art poor, the service life of heat exchanger is short, the technical problem of the low grade of security reliability.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals: the heat exchanger tube location structure of a kind of top board, including top board and several heat exchanger tube positioning through hole of being located on top board, interspersed fixed anticorrosive heat exchanger tube in heat exchanger tube positioning through hole, the anticorrosive heat exchanger tube mouth of pipe interpolation corresponding at described top board outer surface is connected to positioning sleeve, the upper port of positioning sleeve horizontally outward extends on the outer surface being overlapped on top board, the lower port of positioning sleeve extends in the mesopore of anticorrosive heat exchanger tube, and it is provided with annular ex-pansion groove on the heat exchanger tube positioning through hole inwall corresponding with positioning sleeve, anticorrosive heat exchanger tube expanded joint is on the outer corresponding heat exchanger tube positioning through hole inwall of annular ex-pansion groove.By grafting positioning sleeve in the upper port of anticorrosive heat exchanger tube, make anticorrosive heat exchanger tube expanded joint on the internal face of heat exchanger tube positioning through hole by positioning sleeve, good airproof performance between anticorrosive heat exchanger tube and top board, fixed form is simple and reliable, the positioning through hole internal face that positioning sleeve is corresponding arranges annular ex-pansion groove, annular ex-pansion groove provides enough spaces to anticorrosive heat exchanger tube expanded by heating, stress rupture is little, simultaneously because the upper port of positioning sleeve horizontally outward extends on the outer surface being overlapped on top board, easy accessibility, and the downward sliding of anticorrosive heat exchanger tube can be avoided；Anticorrosive heat exchanger tube can avoid flue gas corrosion, extends the service life of heat exchanger.
As preferably, the inner surface of described top board is provided with fluoroplastics inner liner.By arranging fluoroplastics inner liner at the inner surface of top board, the harmful substance corrosion top board can being prevented effectively from flue gas, extend the service life of heat exchanger.
As it is further preferred that the outer ring surface that described fluoroplastics inner liner carries over anticorrosive heat exchanger tube is downwardly extending clamping ring, clamping ring is clamped on the outer ring surface of anticorrosive heat exchanger tube.Fluoroplastics inner liner is downwardly extending and the clamping ring of anticorrosive heat exchanger tube outer ring surface interworking, and fluoroplastics inner liner props up the outer ring surface of anticorrosive heat exchanger tube by clamping ring seal, it is to avoid flue gas enters corrosion top board from both gaps, improves reliability.
As preferably, the outer surface of described top board is provided with the outer lining of fluoroplastics.By arranging the outer lining of fluoroplastics at the outer surface of top board, improve the corrosion resistance of top board outer surface further, extend the service life of heat exchanger.
As it is further preferred that described annular ex-pansion groove extends upwardly to the outer surface of top board, the outer lining of fluoroplastics forms locating ring in extending downward annular ex-pansion groove, and the upper end of anticorrosive heat exchanger tube is folded in outer ring surface and the location interannular of positioning sleeve.Annular ex-pansion groove connects the outer surface of top board, the outer lining of fluoroplastics forms locating ring in extending downward annular ex-pansion groove, owing to fluoroplastics have certain elasticity relative to metal material, when the upper end of anticorrosive heat exchanger tube is folded in positioning sleeve with location interannular, improve the sealing of anticorrosive heat exchanger tube junction.
As preferably, described anticorrosive heat exchanger tube is fluoroplastics material.Due to fluoroplastics corrosion resistance and stablize, and non-stick is by force, and therefore system will not affect its heat transfer efficiency, stable and reliable operation because of longtime running, and maintenance cost is low, and service life is long.
Therefore, the heat exchanger tube location structure of top board of the present utility model has an advantage that by the upper port grafting positioning sleeve at anticorrosive heat exchanger tube, make anticorrosive heat exchanger tube expanded joint on the internal face of heat exchanger tube positioning through hole, and annular ex-pansion groove is set on the positioning through hole internal face that positioning sleeve is corresponding, annular ex-pansion groove provides enough spaces to anticorrosive heat exchanger tube expanded by heating, and stress rupture is little；Annular ex-pansion groove connects the outer surface of top board, and the outer lining of fluoroplastics forms locating ring in extending downward annular ex-pansion groove, when the upper end of anticorrosive heat exchanger tube is folded in positioning sleeve with location interannular, improves the sealing of anticorrosive heat exchanger tube junction；The upper port of positioning sleeve horizontally outward extends on the outer surface being overlapped on top board, easy accessibility, and fixed form is simple and reliable；The inside and outside lining of fluoroplastics improves the corrosion resistance of heat exchanger, extends the service life of heat exchanger.
