Description
Technical field
It the utility model is related to the waste heat boiler device in a kind of afterheat generating system.
Background technology
Afterheat generating system includes waste heat boiler, steam turbine, condenser and condensate pump, and waste heat boiler utilizes industrial waste gas
In heat water is heated to produce steam, steam caused by waste heat boiler is delivered to steam turbine by steam pipework,
The energy of steam is converted into mechanical energy to drive generator operation by steam turbine, and condenser is used for steam condensation is then logical into water
Cross condensate pump and be delivered to waste heat boiler.It is general that a waste heat boiler is only set in current afterheat generating system, so, when
When industrial gas emission amount is larger, a waste heat boiler can not often make full use of waste-gas heat, cause the waste of waste-gas heat.
Utility model content
Technical problem to be solved in the utility model is to provide the waste heat boiler device in a kind of afterheat generating system,
It is provided with two waste heat boilers, can make full use of waste-gas heat.
In order to solve the above technical problems, the waste heat boiler device in afterheat generating system provided by the utility model, it is wrapped
One first waste heat boiler, one second waste heat boiler and a waste gas header are included, the exhaust gas inlet of the first waste heat boiler passes through the first pipe
Road is connected with waste gas header, and the first valve is provided with the first pipeline, and the exhaust gas inlet of the second waste heat boiler passes through the second pipe
Road is connected with waste gas header, and the steam of the second valve, the first waste heat boiler and the second waste heat boiler is provided with the second pipeline
Outlet is connected by pipeline with the steam inlet of steam turbine.
Preferably, the first described waste heat boiler and the waste gas outlet of the second waste heat boiler pass through pipeline and a desulfurization
Deduster is connected.
Preferably, described waste gas header is also connected by one the 3rd pipeline with desulfurizing dust-collector, on the 3rd pipeline
It is provided with one the 3rd valve.
After above structure, the utility model compared with prior art, has the following advantages that：
Waste heat boiler device of the present utility model, the first waste heat boiler and the second waste heat boiler are provided with, so, work as industry
When discharge amount of exhaust gas is larger, the first valve and the second valve can all be opened, now, waste gas can be shunted, waste gas point
Do not enter in the first waste heat boiler and the second waste heat boiler to be evaporated heating, the first waste heat boiler and the second waste heat to water
Steam caused by boiler enters steam turbine acting, so, by waste heat boiler device of the present utility model, can be arranged in waste gas
Waste-gas heat is made full use of when high-volume larger, avoids the waste of waste-gas heat.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the waste heat boiler device in the utility model afterheat generating system include one first waste heat boiler 1,
One second waste heat boiler 2 and a waste gas header 3, the exhaust gas inlet of the first waste heat boiler 1 pass through the first pipeline 4 and waste gas header 3
It is connected, the first valve 5 is provided with the first pipeline 4, the exhaust gas inlet of the second waste heat boiler 2 passes through the second pipeline 6 and waste gas
House steward 3 is connected, and the steam (vapor) outlet of the second valve 7, the first waste heat boiler 1 and the second waste heat boiler 2 is provided with the second pipeline 6
It is connected by pipeline with the steam inlet of steam turbine 8, can be by the He of the first valve 5 when industrial gas emission amount is larger
Second valve 7 is all opened, and now, the waste gas in waste gas header 3 can be shunted, and the waste gas in waste gas header 3 passes through respectively
First pipeline 4 and the second pipeline 6 are entered in the first waste heat boiler 1 and the second waste heat boiler 2 to be evaporated heating to water, the
Steam caused by one waste heat boiler 1 and the second waste heat boiler 2 enters steam turbine 8 and done work, and steam turbine 8 drives electrical power generators.
The first described waste heat boiler 1 and the waste gas outlet of the second waste heat boiler 2 pass through pipeline and a desulfurizing dust-collector 9
It is connected, so, after the first waste heat boiler 1 and the discharge of the second waste heat boiler 2, waste gas enters in desulfurizing dust-collector 9 waste gas
Desulfurization and dedusting is carried out, then waste gas is discharged into air again, and the harmful substance in waste gas can be avoided to pollute environment.
Described waste gas header 3 is also connected by one the 3rd pipeline 10 with desulfurizing dust-collector 9, is set on the 3rd pipeline 10
There is one the 3rd valve 11, so, can be by the first valve 5 when the first waste heat boiler 1 and the second 2 catastrophic failure of waste heat boiler
Closed with the second valve 7, the 3rd valve 11 is opened, now the waste gas in waste gas header 3 can directly pass through desulfurizing dust-collector 9
Discharged after purification.
Explanation only is made that using preferable example with regard to the utility model above, but is not to be construed as to claim
Limitation, structure of the present utility model can have other changes, be not limited to said structure.In a word, it is all of the present utility model only
The various change made in vertical scope of the claims is in the scope of protection of the utility model.
