Description
Technical field
The present invention relates to a kind of high effective flue gas coolers, are mainly used in the production system of glass furnace.
Background technique
In traditional technology, the dust content of glass furnace is relatively high, and relatively high containing hardness such as silica
Dust, higher containing alkali, adhesion is stronger, and deashing is not easy.
As the environmental requirement of country is higher and higher, it is more capable that original contaminating enterprises will re-start technology, whole energetically
The serious enterprise of pollution treatment dyeing technique.The enterprise of glass furnace is the enterprise of a high pollution, the current exhaust gas temperature of glass furnace
It is excessively high, without dedusting, denitration and desulfurization, in order to meet the environmental requirement of country, it is necessary to for the excessively high flue gas of exhaust gas temperature into
Row dedusting, denitration and desulfurization process, however 600 DEG C are up to from the flue gas that glass furnace comes out, it is not able to satisfy dedusting, high temperature takes off
Nitre and the requirement of the technique of desulfurization, it is therefore necessary to flue-gas temperature be reduced using high-performance heat exchanger.
Existing air preheater major part time uses light pipe or bellows as its heat exchange element at present, and passes through
Its tube bank of flue gas transversal flow is to exchange heat.Since light pipe does not have enhanced heat exchange, the extremely low coefficient of heat transfer of heat exchange efficiency is generally
15~20W/ (㎡ DEG C), cause the weight and volume of air preheater increased dramatically.Bellows heat exchanger coefficient ratio light pipe is increased,
There is certain strengthening effect, but effect is not obviously, to increase in ripple bring pipe with the resistance outside pipe instead, is easy to tie yet
Dirt, seriously corroded.In order to solve regular air preheater or gas cooler heat exchange efficiency is low causes weight and volume huge,
The problem of resistance is big, is easy fouling corrosion and leads to the more nervous field condition in original space, will introduce a kind of high efficient heat exchanging
Pipe is the task of top priority of current gas-to-gas heat exchanger problem.
Patent of invention content
The purpose of the present invention is to provide a kind of high effective flue gas coolers, to solve glass furnace system limited installation space
Problem solves resistance, mitigates abrasion and stifled ash, extends equipment life, and can reduce exhaust gas temperature, meets environmentally friendly upgrading
Technique requirement, at the same avoid gas cooler because stifled ash, abrasion, heat exchange efficiency is low due to lead to Problem of Failure.
In order to achieve the above object, the invention proposes technical solutions below:
A kind of high effective flue gas cooler, including gas inlet, exhanst gas outlet, and at least one piece be set to gas inlet and cigarette
Heat exchange module between gas outlet, heat exchange module include a cube of frame, are provided with several rows by Gao Bibiao in cube frame
The pipe row of the efficient pipe composition in face, the efficient pipe of high-ratio surface is axial vertical with flow of flue gas direction, efficiently manages perpendicular to high-ratio surface
Axial frame end face is provided with tube sheet, and frame top and bottom end are provided with side plate, and air flows in high-ratio surface is efficiently managed,
Flue gas flows in the space being made of tube sheet, side plate and the efficient tube outer surface of high-ratio surface.
High-ratio surface is efficiently managed as helical structure.
Spacing between pipe row and pipe row is greater than the efficient pipe maximum outside diameter of high-ratio surface.
Spacing between the Guan Yuguan of pipe row is equal with the efficient pipe maximum outside diameter of high-ratio surface, passes through salient point between Guan Yuguan
It contacts, by being welded and fixed between salient point, keeps pipe row's shape integral.
Each pipe is discharged from be respectively provided with wearing-resistant tile on the outside of the efficient pipe of the nearest high-ratio surface of smoke air inlet.
Along flow of flue gas direction, pipe row's density in frame is gradually increased.
The heat-transfer surface of low-level (stack-gas) economizer is solved using the efficient pipe of high-ratio surface as the heat exchange element of gas cooler
The coefficient of heat transfer of gas cooler is small, saves the heat exchange area and space problem of heat exchanger.Using advanced piping mode, subtract
Slight drag prevents the heat-transfer surface fouling of cooler and leads to dust stratification, realizes three-dimensional emptying design concept, makes flow field
It is " salient point " contact between the efficient pipe of high-ratio surface, does not need external support construction, spot welding forms one between pipe
It is whole, improve section of jurisdiction rigidity, so that it is supported mutually between Guan Yuguan, it will not the flow velocity of extratubal fluid is very high
Form heat exchanging bundle vibration impact.
When fluid flows in pipe or outside pipe, due to being influenced by helical structure special in high-ratio surface pipe,
So that destroying thermal boundary layer, so that thermal boundary layer is thinning, the heat exchange of cold fluid and hot fluid is enhanced.And improve outflow in pipe
Body heat transfer effective distance.Because the fluid of central part is substantially not engaged in heat exchange in the pipe of common round tube,
Heat exchange efficiency is low.Exactly because three dimension high efficiency pipe shortens the heat transmission effective distance inside and outside pipe by optimization deformation, improve
Heat transfer efficiency.
Since gas cooler import is temperature end, volume flow is very big, and the impact for exchanging heat pipe is very big, and abrasion adds
Play, resistance increase, therefore increase circulation area, guidance using flexible " water conservancy diversion " formula stringing in the heat exchanger tube of input end arrangement
Flue gas than smoothly, it is comfortable enter heat-exchanging tube bundle, reduce vortex and lead to drag losses, and tune up heat exchange tube spacing, reduce
Flue gas flow rate is to zone of reasonableness.And the flue gas volume flow in gas cooler outlet end becomes smaller, it is appropriate to increase the close of heat exchanger tube
Degree reduces circulation area, improves flue gas flow rate to zone of reasonableness.Pass through the inlet and outlet and intermediate tube bank of pipe gas cooler
Using different piping modes, increase the gap of inlet and outlet circulation area, and then reduces current difference away from so that entirely changing
The flow velocity of heat pipe bundle is in relatively uniform degree, optimizes flow field.
The tube bank of gas cooler is set using pipe arrangement, that is, tube bank is made of pipe row, the row between pipe row and pipe row
Spacing is greater than the efficient pipe maximum outside diameter of high-ratio surface, it is therefore an objective to reduce and manage outer flow velocity, reduce the drag losses of tube bank.The pipe of pipe row
Spacing between pipe is equal with the efficient pipe maximum outside diameter of high-ratio surface, that is, contacts with each other between Guan Yuguan, mutually supports,
And the contact that connects between the pipe of pipe row, which uses, to be welded and fixed to form an entirety, it is therefore an objective to which the rigidity for increasing pipe row prevents cigarette
Gas Cooler generates a possibility that vibration, reduces vortex and is formed, and reduces pipe external resistance loss, slows down heat exchange pipe abrasion, extends cigarette
The service life of Gas Cooler.
Gas cooler uses modularization, standardized designs, production, and can carry out flexible group according to actual needs
Dress shortens manufacture, the supply of material and set-up time, reduces cost.
The invention has the benefit that
First, heat exchange element heat exchange efficiency is high;
Second, vibrationproof performance is good, small in size;
Third, flue gas flow field is highly uniform, is not easy dust stratification;
4th, fume side imports and exports special cloth form of tubes, and tube bank uses different tube spacing, reduces tube bank different zones stream
