Utility model content
The purpose of this utility model is to provide a kind of circular seam type high-temperature heat-exchanging, and it has the feature of the high and energy-conserving and environment-protective of long service life, heat exchange efficiency, to solve the problems referred to above that in prior art, circular seam type high-temperature heat-exchanging exists.
For reaching this object, the utility model by the following technical solutions:
A kind of circular seam type high-temperature heat-exchanging, it comprises lower joint interchanger, upper joint interchanger, damping wind section and smoke evacuation section, wherein, described lower joint interchanger adopts downflow system structure, be provided with cold wind import bottom it and be sleeved on melting furnaces vertical gas pass, top connects the bottom of upper joint interchanger by joint flange, described upper joint interchanger adopts counter flow type structure, hot-blast outlet is provided with bottom it, the top of described lower joint interchanger and the top of described upper joint interchanger are connected with the first heat exchanger channels, and the top of described upper joint interchanger is connected with Weighting system, described damping wind section is provided with damping wind inlet, connected the top of upper joint interchanger by joint flange bottom it, and be connected with the second heat exchanger channels between the top of described damping wind section and bottom, the bottom of described smoke evacuation section is connected to the top of described damping wind section, described lower joint interchanger, upper joint interchanger, damping wind section all adopts two-layer telescopic heat exchange structure, in comprising, outer sleeve, the outer wall of described inner sleeve is fixed with spiral heat conduction bar, gap is left between described heat conduction bar and the inwall of outer sleeve, after inner sleeve heating, described heat conduction bar expands and is closely attached on the inwall of described outer sleeve.
Especially, the bottom of described lower joint interchanger is provided with and is convenient to the aligning device that it is installed on glass melter.
Especially, the top of described smoke evacuation section is provided with for the first row mouth by smoke directly ventilating, coordinate described first row mouth to be provided with top cover to be opened/closed, described top cover is connected with windlass, and described smoke evacuation section is also provided with the second row mouth for flue gas being carried out purifying treatment.
Especially, described heat conduction bar lead angle controls between 48 DEG C ~ 55 DEG C, to reduce the resistance that hot blast flows in interchanger.
Especially, described Weighting system comprises 4 cover sister block assemblies, steel cable and balancing weight, and one end of described steel cable is connected to the top of described upper joint interchanger, and the other end connects balancing weight through described 4 cover sister block assemblies.
Especially, described hot-blast outlet is connected with the airduct for carrying out UTILIZATION OF VESIDUAL HEAT IN.
The beneficial effects of the utility model are, compared with prior art described circular seam type high-temperature heat-exchanging has the following advantages:
1) high-temperature heat-exchanging maximum diameter is 2.2 meters, and be the overall dimension of the current this form in the world, the shell structure under major diameter is exactly the process utilizing heat conduction bar, makes it at high temperature not easily produce distortion.
2) in order to improve the work-ing life of interchanger, heat exchanger wall must just be controlled well not by high temperature oxidation and corrosion.Interchanger itself is all be spliced into an one-piece construction by heat-resistance stainless steel, and itself deadweight is up to 10 tons of weights, if to bear its stress born by certain part just quite serious for this weight.If the high-temperature zone of bearing, serious high temperature corrosion will be produced, will soon be burned.Described high-temperature heat-exchanging connects Weighting system in the top of upper joint interchanger, upper joint interchanger and damping wind section is lifted, carries out stress transfer, make interchanger be in safety production environment.
3) heat conduction bar arranges the effect of main several respects, on the one hand mainly by the heat of flue gas by radiation delivery to the heat conduction bar of heat exchanger wall, to be contacted with air by big area and carry out heat exchange.On the other hand interchanger inner sleeve is connected by heat conduction bar with outer sleeve, inner sleeve after the heating diameter will strengthen, can be connected together tightly with outer sleeve by heat conduction bar, the weight of inner sleeve will be brought in outer sleeve, the temperature of relatively bearing due to outer sleeve is lower, just make the stress of the high-temperature part bottom inner sleeve significantly reduce, also just eliminate the danger of stress corrosion.Outer sleeve steel plate is thinner simultaneously, and easily distortion adapts to the change of inner sleeve, although inner sleeve and outer sleeve link together, but still can produce slippage each other.
4) in order to adapt to the interchanger of pure oxygen burning, after considering combustion of natural gas, producing a large amount of superheated vapor, be combined into strong acid with related substance in raw material, as run into freezing air, easily will produce condensation, making equipment cause corrosion damage.High-temperature heat-exchanging is that damping wind section is adopted 2 layers of telescopic heat exchange, produces the hot blast of about 300 DEG C, solve the contradiction of condensation in less size.
5) along with pure oxygen burning production technique is applied on glass melter, the change of interchanger in order to conform, occurs with new structure formation as UTILIZATION OF VESIDUAL HEAT IN.As the interchanger of fibre glass roving kiln, its heat exchange air produced can as the oven dry thermal source of strand drying, and its quality is higher than steam heat-exchanging, and the hot blast of energy direct production about 250 DEG C, heat exchange efficiency can reach about 80%, and its smog discharge temperature can control to about 250 DEG C.Directly off gas treatment can be carried out when not reaching condensation, save waste heat boiler and too much off gas treatment amount (flue-gas temperature is down to 650 DEG C by 1400 DEG C by the unit air inducing mode had at present), both boiler increases volumetric had been caused, and off gas treatment amount also doubles many, cost is caused to increase.As glass fiber spun yarn kiln, because the precursor produced does not need drying production process, interchanger is produced about 450 DEG C warm airs and is carried out waste heat boiler production steam, because warm air is clean, can reheat by consumption, or direct production hot water.And flue gas is less because measuring, the exhaust gas volumn much less relatively without interchanger after waste heat boiler, also just makes the cost of off gas treatment greatly reduce (point two line process).
