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，Keep between heat exchanger tube upper end and housing tube sheet being tightly connected，The lower end of heat exchanger tube extends in flue through limiting plate，Its Central Plains exhaust gases passes is heat exchanger tube，Limiting plate superjacent air space is neat stress passage，In order to prevent former flue gas to be mixed in neat stress through the via on limiting plate，Heat exchanger tube in structure is usually rigid seal with limiting plate and is connected，And heat exchanger tube generally to have expansion rate big，The feature that phenomenon of expanding with heat and contract with cold is obvious，Heat exchanger tube is the most easily caused freely to stretch，Local deformation amount is big，Reduce the problems such as heat exchanger service life.
Summary of the invention
This utility model mainly provides a kind of simple in construction; can ensure that heat exchanger tube is in setting position stable pulling and contraction; it is prevented effectively from the structure preventing gas-gas heat exchanger heat exchanger tube thermal expansion to lose efficacy of heat exchanger tube deformation; solve heat exchanger tube present in prior art cannot freely stretch when using; cause local deformation amount big, reduce the technical problem in heat exchanger service life etc..
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals: a kind of structure preventing gas-gas heat exchanger heat exchanger tube thermal expansion to lose efficacy, including heat exchanger shell and some fluoroplastics heat exchanger tubes of being hung in heat exchanger shell, heat exchanger tube limiting plate it has been horizontally set with in described heat exchanger shell, heat exchanger tube limiting plate is provided with the heat exchanger tube location hole corresponding with fluoroplastics heat exchanger tube, fluoroplastics heat exchanger tube extends to the lower section of heat exchanger tube limiting plate through hole, heat exchanger tube location, and it is set with heat exchanger tube telescopic outside the fluoroplastics heat exchanger tube of correspondence above heat exchanger tube limiting plate, between the outer ring surface of the airtight internal face being clamped in hole, heat exchanger tube location in the lower end of heat exchanger tube telescopic and fluoroplastics heat exchanger tube.Owing to fluoroplastics have heat-exchange performance, corrosion resistance and good stability, and the feature such as non-stick is strong, therefore during system longtime running, fluoroplastics heat exchanger tube all can keep the highest heat transfer efficiency, system run all right is reliable, maintenance cost is low, service life is long, by horizontally set heat exchanger tube limiting plate in heat exchanger shell, fluoroplastics heat exchanger tube is made to be inserted through heat exchanger tube limiting plate, and heat exchanger tube telescopic is set between heat exchanger tube limiting plate and fluoroplastics heat exchanger tube, can freely stretch by the through hole along heat exchanger tube limiting plate when fluoroplastics heat exchanger tube expands with heat and contract with cold, during use due to heat exchanger tube telescopic with heat exchanger tube relative to heat exchanger tube limiting plate synchronization telescope, therefore heat exchanger tube can be made to maintain on setting position, simple in construction, effectively support heat exchanger tube and avoid the deformation of heat exchanger tube, raising system reliability of operation.
As preferably, heat exchanger tube telescopic includes the cyclic spring body being sleeved on outside fluoroplastics heat exchanger tube, the lower end of cyclic spring body extends in hole, heat exchanger tube location, on the inner ring surface of cyclic spring body, several O locating slots axially aligned, are embedded with O sealing ring in O locating slot.By being embedded in several O sealing rings at the inner ring surface of cyclic spring body, the sealing between heat exchanger tube telescopic and fluoroplastics heat exchanger tube can be improved by O sealing ring, cyclic spring body defines stable support to fluoroplastics heat exchanger tube simultaneously, thus reaches to be prevented effectively from the purpose of heat exchanger tube deformation.
As it is further preferred that described cyclic spring body is fluoroplastics material.Cyclic spring material as the use of fluoroplastics heat exchanger tube, thermal deformation is consistent, it is to avoid fluoroplastics heat exchanger tube telescopic process produces stress and concentrates.
As preferably, described heat exchanger shell includes main casing and is docked at the lower posting of main casing lower port, and heat exchanger tube limiting plate is folded between main casing and lower posting.Lower posting is easy to the assembling combining installation and heat exchanger tube and heat exchanger tube limiting plate of main casing.
As preferably, described heat exchanger tube limiting plate is fluoroplastics material.The corrosion resistance of fluoroplastics and good stability, non-stick is strong, and maintenance cost is low, and service life is long.
Therefore, the structure preventing gas-gas heat exchanger heat exchanger tube thermal expansion to lose efficacy of the present utility model has an advantage that by horizontally set heat exchanger tube limiting plate in heat exchanger shell, make fluoroplastics heat exchanger tube lower end be interspersed on heat exchanger tube limiting plate to be connected with flue, and heat exchanger tube telescopic is set between heat exchanger tube limiting plate and fluoroplastics heat exchanger tube, can freely stretch by the through hole along heat exchanger tube limiting plate when fluoroplastics heat exchanger tube expands with heat and contract with cold, due to heat exchanger tube telescopic with heat exchanger tube relative to heat exchanger tube limiting plate synchronization telescope, therefore heat exchanger tube can be made to maintain on setting position, simple in construction, seal reliable, and effectively support heat exchanger tube and avoid heat exchanger tube deformation, raising system reliability of operation.
