Definitions

the invention relates to a method and a system for the condensation of excess steam occurring in steam generation and consumption systems in a condenser with indirect heat exchange.
a particular disadvantage of releasing the steam into the atmosphere is e.g. B. the loss of the generally high quality treated water; the environment is also polluted by noise and swaths. If the steam is led over such emergency condensers, the connection with the atmosphere absorbs oxygen in the condensate, which can lead to corrosion and the introduction of corrosion products into the steam system. Drainage regulations of the condensate react very sluggishly and are therefore only of limited use.
the object of the invention is to provide a solution with which blowing into the atmosphere is unnecessary and with which in particular the access of oxygen to the generated condensate is prevented.
this object is achieved according to the invention in that the condenser is filled with an oxygen-free fluid which is displaced by the excess steam in a receiving reservoir, the fluid being returned to the condenser when the excess steam is eliminated.
the invention also provides that the condenser is followed by a condensate container with a gas dome, which is used to hold the inert gas and, if necessary, to compress it.
This embodiment has the advantage that during displacement of the inert gas therein, a pressure increase is generated on the capacitor in the gas dome, which at V errin- delay the amount of condensate repektive effected with omission of introduced excess steam that the inert gas immediately flows back into the condenser. This procedure facilitates or shortens the regulation, in particular the response times of the system.
the invention also provides a system for solving the underlying problem, which is characterized in that the condensate collector of the condenser is followed by a condensate tank with a steam dome, a first line for discharging the condensate and starting from the gas dome between the condensate collector and the condensate tank a second line for the inert gas are arranged.
This solution specially selected for inert gases, has the advantage that it reacts very quickly, is structurally simple and therefore economical and is suitable for a large number of possible uses.
the gas dome is designed with a connecting line to the condensate collector for receiving all of the inert gas contained in the condenser.
This configuration ensures that the maximum working pressure occurs when the condenser is fully exposed to steam.
This increased pressure has an additional advantage, namely that the pressure level in the condenser is significantly above a working pressure that prevails in the case of open condensers, ie compared to atmospheric pressure. Due to the increased pressure level, the condensation temperature of the steam and thus the mean loga increases rithmic temperature difference, so that the heat exchanger surfaces can be made smaller than in the case of condensers with atmospheric pressure.
the system generally designated 1, has an air-cooled condenser 2 in a pent roof construction.
the blower is designated 3, it being noted at this point that all parts of the system are only sketched in principle.
the condenser 2 has a condensate collector 4, which is followed by a condensate container 5 in the flow direction of the condensate.
the capacitor 2 is acted upon an excess steam supply line 6, which branches off from the main network 7 and can be switched via corresponding control devices 8.
the condensate collection container 5 has a gas dome designated 9.
An inert gas line 10 is provided between the gas dome 9 and the upper regions of the condensate collector 4, and a condensate discharge line 11 is provided from the underside of the condensate collector 4.
FIG. 1 also shows an inert gas supply line 12 with control device 13 and a condensate return line 14 also with control devices 15 and possibly a pump 16, which is not important here in detail.
valve 8 closes, the condensate runs off, the increased pressure generated by the shifting of the nitrogen in the gas dome 9 leading to the nitrogen immediately returning via the line 10 and the condensate collector 4 into the Capacitor is pushed back. This ensures that oxygen cannot reach the condensate at any point in the system.
the arrangement is supplemented by an ejector 17 with a cooler part 18 connected downstream.
the inert gas is drawn off via the ejector 17 and passed over a separated part of the heat exchanger. This increases the speed in the heat exchanger tubes and the heat transfer in the residual steam area.
the system again has an air-cooled condenser 2 in a pent roof construction. It is supplemented by a pressure-dependent ejector 17 and a divided after-cooling surface 18.
Condensate flows through the standpipe 11 into the condensate collection container 9. Displaced intergas flows through a line 19 to the ejector 17.
the ejector 17 When the pressure in line 19 increases, the ejector 17 is subjected to steam and the inert gas is conveyed via line 21 to a post-cooling part 18; the inert gas is cooled, motive steam and attached vapors are condensed.
the condensate flows through a standpipe 22 into the condensate collection container, the inert gas reaches the gas dome via the connecting line 10.
a water level is set in the standpipe 11, which corresponds to the pressure difference between the condensate pipe or cooler 2 and the after-cooling part 18.
Oils are used, so surge tanks can be provided. In this case, oil separators and the like. Like. appropriate. Capacitors cooled with water or another medium can also be used. If a water-cooled condenser were used instead of the air-cooled condenser, the steam in the basic circuit described is expediently to be carried on the pipe side and the cooling medium on the casing side in order to achieve a clear flow and displacement of the inert gas.
