Description
Technical field
The utility model relates to a kind of rubbish/biomass and coal coupled electricity-generation system, belong to technical field of power generation.
Background technique
Currently, rubbish or biomass and coal coupled electricity-generation have following methods：1, rubbish or biomass and coal are directly mixed
It burns, although small investment in this way, operation is simple, and the heavy metal in rubbish can mix in combustion product gases and waste residue,
It can not be handled, cause heavy metal to spread with the utilization of waste residue, there are potential risk of environmental pollution；2, rubbish or
Burning is mixed after gasification of biomass with coal, its advantage is that generating efficiency is high, the influence to coal-burning boiler is small.But its investment is huge, fortune
Row is complicated, and using energy source is low；3, the high-temperature flue gas produced after rubbish or biomass combustion is passed through in coal-burning boiler, its own is not generated
Steam, but since high-temperature flue gas brings flying dust into coal-burning boiler, be contaminated the coal-fired flying dust generated, be unfavorable for flying dust
Processing and utilization.
Utility model content
To solve technical problem of the existing technology, it is simple that the utility model provides a kind of structure, easy to use, energy
Generating efficiency is enough improved, the rubbish/biomass and coal coupled electricity-generation system of secondary pollution are avoided.
To achieve the above object, technical solution used by the utility model is that a kind of rubbish/biomass couples hair with coal
Electric system, including rubbish/biomass combustion boiler and coal-burning boiler, the exhanst gas outlet of the rubbish/biomass combustion boiler according to
Secondary to be connected with denitrification apparatus and deduster, the exhanst gas outlet of the coal-burning boiler is connected with denitrification apparatus, deduster in turn and takes off
The flue gas of sulphur tower, the rubbish/biomass combustion boiler is connected after denitration, dedusting with desulfurizing tower, and the coal-burning boiler produces
Raw high-temperature steam is connected by the first jet chimney with steam turbine, the high temperature that the rubbish/biomass combustion boiler generates
Steam is connected by the second jet chimney with the first jet chimney, is provided with non-return valve on second jet chimney, described
The condensed water of steam turbine is connected with rubbish/biomass combustion boiler, coal-burning boiler respectively by feed pump.
Preferably, the rubbish/biomass combustion boiler is grate furnace or circulating fluidized bed boiler.
Preferably, the steam that the rubbish/biomass combustion boiler generates is by the way of Natural Circulation.
Compared with prior art, the utility model has the following technical effects：The utility model structure is simple, user
Just, the flue gas generated using rubbish/biomass combustion boiler is passed into desulfurizing tower after denitration, dust removal process, using de-
The oxidation of nitre and wet desulphurization effect, solve the problems, such as the heavy metal in rubbish；Rubbish/biomass combustion boiler generates simultaneously
Steam and coal-burning boiler generate steam enter in steam turbine, effectively increase the generating efficiency of steam turbine.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with
Lower combination accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein
It applies example to be only used to explain the utility model, is not used to limit the utility model.
As shown in Figure 1, a kind of rubbish/biomass and coal coupled electricity-generation system, including 1 He of rubbish/biomass combustion boiler
Coal-burning boiler 2, the exhanst gas outlet of rubbish/biomass combustion boiler 1 are connected with denitrification apparatus 3 and deduster 4, coal-burning boiler in turn
2 exhanst gas outlet is connected with denitrification apparatus 2, deduster 3 and desulfurizing tower 5, the flue gas warp of rubbish/biomass combustion boiler 1 in turn
It is connected after denitration, dedusting with desulfurizing tower 5, the high-temperature steam that coal-burning boiler 2 generates passes through the first jet chimney 6 and steam turbine 7
It is connected, the high-temperature steam that rubbish/biomass combustion boiler 1 generates is connected by the second jet chimney 8 with the first jet chimney 6
Connect, be provided with non-return valve 9 on the second jet chimney 8, the condensed water of steam turbine 7 by feed pump 10 respectively with rubbish/biomass
Burning boiler 1, coal-burning boiler 2 are connected.Wherein, rubbish/biomass combustion boiler 1 can use grate furnace or recirculating fluidized bed
Boiler.The flue gas generated using rubbish/biomass combustion boiler is passed into desulfurizing tower after denitration, dust removal process, is utilized
The oxidation of denitration and wet desulphurization effect, solve the problems, such as the heavy metal in rubbish；Rubbish/biomass combustion boiler produces simultaneously
The steam that raw steam and coal-burning boiler generates enters in steam turbine, effectively increases the generating efficiency of steam turbine.Due to rubbish/
The calorific value of biomass is lower, need biomass combustion boiler, coal-burning boiler jet chimney between install non-return valve, and rubbish additional
The steam that rubbish/biomass combustion boiler 1 generates is by the way of Natural Circulation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
