Definitions
- the invention relates to a network of lines for a medium, in particular for gas in a converter steelworks, and a method for its operation.
- the invention relates to a converter steelworks with the network according to the invention.
- Networks of lines are known in principle, in particular in converter steel works.
- warm converter waste gas is produced, which is typically stored temporarily in a container for further use.
- the converter exhaust gas is routed via the network of (gas) lines via the container to a consumer.
- the converter exhaust gas is exhaust gas that is produced during the operation of the converter. This converter waste gas is typically up to 100% saturated with water vapor.
- the invention is based on the object of developing a known network of lines for a medium, a method for operating such a network and a converter steelworks with such a network in such a way that icing within the Storage container for the medium and resulting disturbances of the storage container operation can be avoided.
- the claimed network is characterized by a return line for conducting at least part of the medium in the line downstream of the booster fan back into the storage tank.
- medium here means a liquid or a gas, in particular converter exhaust gas.
- valve means in particular a flap or a throttle.
- storage container only the term “container” or “reservoir” is used below for simplification.
- the converter Due to the operation of the pressure booster fan, in particular for the return of the medium back into the container, the converter exhaust gas heats up due to the mechanical work that is performed on the medium flowing through. With the claimed return of the medium heated in this way, the container is also heated again and ultimately protected against freezing. The operational safety of the container is increased in this way.
- Container is routed to a consumer, different lines must be enabled or blocked in the network; to this end, according to a first exemplary embodiment, the pressure-boosting blower in the line has valves upstream and/or downstream for throttling or shutting off the
- the claimed converter steelworks with a converter in a converter operation as the source for the gas to be transported here as the medium is, of course, merely an example.
- the subject matter of the invention is independent of the type of medium routed through the network of lines.
- the invention is accompanied by a figure showing the network of lines for media according to the invention.
- the network includes a supply line 105 for supplying medium, for example converter waste gas, from a gas source 210, for example a converter 210 in a converter steelworks, into a container 110.
- the medium is supplied via the inlet 112 of the container 110.
- the medium stored in the container 110 can be routed to a consumer 150 via the network 100 of lines according to the invention.
- the network 100 includes, in addition to the supply line 105, the container 140 and a line 120 to the consumer 150.
- the pressure booster fan is connected in the line between the outlet 114 of the container 110 and the consumer 150, which also acts as a driving device for the medium from the Container 110 to the consumer 150 acts.
- booster fan means that the pressure of the medium in the line 120 downstream of the booster fan is higher than on the inlet side 112 of the booster fan.
- the valves 124, 126 allow the network 100 to operate in the cold-only mode; then valves 124 and 126-1 and 126-2 are open while valve 126-3 is closed.
- the medium heated by the pressure booster fan is then fed back to the container 110 via the medium return line 160 in order to protect it from unwanted freezing.
- a heating device in addition to the pressure booster fan 140 to heat the medium, although such an additional heating device is of course not harmful either, ie it can be present.
- valves 124 and 126-1, 126-2 and 126-3 are typically opened to the medium from the container via the booster fan 140 to to carry 150 to the consumer.
- the recirculation line 160 is then typically closed off by means of a valve 126-4.
- Mixed forms between pure cold operation and pure warm operation are of course also possible; in this case, part of the medium is then fed back into the container 110 via the return lines 160, while another part of the medium is conveyed to the consumer 150.
- the consumer can be z. B. be a power plant or a furnace, which use the supplied medium as an energy source for their own combustion processes.
- the described network 100 of lines can, for example, be part of a converter steelworks, the converter steelworks then having not only the network 100 but also a converter 210 which generates the medium to be transported to the consumer 150 in the form of converter exhaust gas.
