Background technology
At present, the connected mode of the existing waste heat boiler that is used for glass production line and glass production line as shown in Figure 1, the useless flue gas that the kiln pond produces enters chimney by adjustment doors, big gate, leans on the natural draft of chimney to enter atmosphere.And the flue gas that enters atmosphere has higher heat, in order to make full use of this part heating power, reaches the purpose of energy-saving and emission-reduction, and residual heat flue is set after adjustment doors, closes big gate.Useless flue gas enters residual heat flue by adjustment doors, by waste heat boiler import baffle door, waste heat boiler, air-introduced machine, heat boiler outlet baffle door, enters chimney at last and enters atmosphere successively.The heat of flue gas is by waste heat boiler the time, and the working medium of waste heat boiler is given in exchange, and the working medium after the heating is admitted to hot users such as steam turbine generator generating or heating.
Above-mentioned existing systems, when normal recovery waste heat generates electricity, big gate is closed, and must open big gate if recovery system is stopped transport, and the big gate heaviness of existing production line, lean on artificial or electronic opening, open slowly, if waste heat recovery generating system is normal stoppage in transit, recovery system can cooperate big gate normally to stop transport slowly, keep the stable of glass production line furnace pressure, do not produce bigger fluctuation; But if accident emergency outage, air-introduced machine is stopped transport immediately, boiler flue inlet or outlet damper door are closed, this is that big gate can not in time be opened, to cause that the glass production line furnace pressure is malleation suddenly, it is bigger to fluctuate, and can have influence on the safe operation of glass production line, produces more serious consequence.
The utility model content
Technical problem to be solved in the utility model provides a kind of glass production line exhaust heat recovery power generation flue system, and this system can effectively guarantee the normal safe operation of glass production line.
The technical scheme that its technical problem that solves the utility model adopts is: glass production line exhaust heat recovery power generation flue system, between adjustment doors on the flue collector in glass production line kiln pond and big gate, be provided with residual heat flue, be sequentially set with gas approach baffle door, waste heat boiler and exhanst gas outlet baffle door on the residual heat flue, it is characterized in that: be provided with the bypass flue before the gas approach baffle door and between the residual heat flue after the exhanst gas outlet baffle door, the bypass flue is provided with the by-pass damper door.
As further improvement in the technical proposal, above-mentioned by-pass damper door and gas approach baffle door are or/and exhanst gas outlet baffle door interlock and controlled by production line control system.
As further improvement in the technical proposal, the aperture of above-mentioned by-pass damper door is adjustable.
As the preferred implementation of technique scheme, the aperture of above-mentioned by-pass damper door is controlled by production line control system.
The beneficial effects of the utility model are: when residual neat recovering system runs into burst accident, when needing emergency outage, the by-pass damper door is opened rapidly, air-introduced machine is stopped transport, the chimney intake baffle door and the outlet damper door of waste heat boiler are closed rapidly, keep the furnace pressure of glass production line, guarantee, can be widely used in the construction of the transformation of existing glass production line waste heat recovery generating system and new production line because the stoppage in transit of residual neat recovering system does not have influence on the safe operation of glass production line.
Description of drawings
Fig. 1 is the schematic diagram of existing glass production line waste heat recovery generating system;
Fig. 2 is the schematic diagram of glass production line waste heat recovery generating system of the present utility model, and the direction of arrow is the flow of flue gas direction among the figure;
Be labeled as among the figure: glass production line kiln pond 1, waste heat boiler 2, chimney 3, air-introduced machine 4, adjustment doors 5, big gate 6, gas approach baffle door 7, exhanst gas outlet baffle door 8, by-pass damper door 9, steam turbine generator 10, flue collector 11, residual heat flue 12, bypass flue 13.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1; existing glass production line exhaust heat recovery power generation flue system; between adjustment doors 5 on the flue collector 11 in glass production line kiln pond 1 and big gate 6, be provided with residual heat flue 12; be sequentially set with gas approach baffle door 7, waste heat boiler 2 and exhanst gas outlet baffle door 8 on the residual heat flue, also be provided with air-introduced machine 4 on the residual heat flue usually.The 1 useless flue gas that produces enters residual heat flue 12 by the adjustment doors 5 on the flue collector 11 in glass production line kiln pond, because when residual neat recovering system normally moves, the big gate 6 on the flue collector 11 is closed.The flue gas that enters residual heat flue 12 carries out heat exchange by the gas approach baffle door 7 of waste heat boiler 2 again in waste heat boiler 2, the flue gas after the heat exchange is extracted by air-introduced machine 4, and the exhanst gas outlet baffle door 8 by waste heat boiler 2 enters chimney 3 and enters atmosphere.Be transported to steam turbine generator 10 generatings by pipeline after working medium is absorbed heat in waste heat boiler 2, the working medium after the acting is got back to waste heat boiler 2 by pipeline and is proceeded heat exchange.
Glass production line exhaust heat recovery power generation flue system of the present utility model, as shown in Figure 2, utilize existing glass production line exhaust heat recovery power generation flue system, be provided with bypass flue 13 between the residual heat flue 12 before gas approach baffle door 7 and after the exhanst gas outlet baffle door 8, bypass flue 13 is provided with by-pass damper door 9.When residual neat recovering system normally moves, by-pass damper door 9 is closed, when residual neat recovering system runs into burst accident, when needing emergency outage, can open by-pass damper door 9 rapidly, make flue gas enter chimney 3, keep the stable of glass production line furnace pressure, thereby effectively guarantee the normal safe operation of glass production line through bypass flue 13.
Because gas approach baffle door 7, exhanst gas outlet baffle door 8 and air-introduced machine 4 are controlled by production line control system usually, and stop transport immediately at accident generation time control making blower fan, the smoke inlet baffle door 7 of waste heat boiler is or/and exhanst gas outlet baffle door 8 is closed at once, and this moment, big gate 6 can not in time be opened.Therefore, preferably with the by-pass damper door on the residual heat flue 12 9 with gas approach baffle door 7 or/and 8 interlocks of exhanst gas outlet baffle door, and by the unified control of production line control system, make it guarantee that by-pass damper door 9 can in time open in needs.Like this, when the big gate 6 when running into burst accident on the flue collector 11 also is in closed condition owing to action lags behind, can open bypass damper door 9 rapidly, close air-introduced machine 4, gas approach baffle door 7 and outlet damper door 8, this moment, useless flue gas was by the adjustment doors 5 on the flue collector 11, enter residual heat flue 12 and enter chimney 3 through the by-pass damper door 9 on the bypass flue 13, enter atmosphere by the nature draft, glass production line is unlikely to be affected owing to the unexpected stoppage in transit of residual neat recovering system like this.
In order better to keep the stable of glass production line furnace pressure, the aperture of by-pass damper door 9 is preferably adjustable, and the aperture of by-pass damper door 9 is preferably controlled by production line control system.
