(Prior art and its problems) A conventional odorant addition device measures the amount of odorant added using a measuring device using a gauge tank a, as shown in FIG. 2, for example. The addition amount is controlled by adjusting the stroke of the odor pump d itself based on the gas delivery amount measured by a gas delivery flow meter c provided in the gas delivery system b. Therefore, in the conventional odorant addition device, an odorizing pump d and a gauge tank a type measuring device are required for each of the plurality of gas delivery systems b, and this measuring device deals with troubles such as the odorizing pump d. Since it is also necessary for the preheating pump e provided for this purpose, there is a problem in that the entire configuration becomes large-scale. In addition, in such conventional odorant addition devices, the measurement cycle is long, the discovery of defective addition of odorant is likely to be delayed, and there is a process in which measurement becomes impossible when replenishing odorant to the gauge tank.
Feedback control of the addition amount is difficult because the distance between the measurement point of the addition amount, that is, the upstream point of the odorizing pump d, and the odorant addition point f for the gas delivery system b, There were problems such as low reliability in this regard, as there was a possibility of errors due to leakage of check valves from the system, or problems with pumps and piping.

(Function) In the above configuration, the odorant that has reached the header 10 via the common odorant addition pump system 6 is
In each odorant addition system 4, the odorant is added via a control valve 2 controlled by a gas delivery flowmeter 5 and an odorant flowmeter 3 to each addition point 12. At this time, in each odorant addition system 4, the odorant flow rate measured by the odorant flow meter 3 is set as the default value, and the gas delivery amount measured by the gas delivery amount flow meter 5 and the reference addition Feedback control can be performed using the odorant set flow rate value, which is a multiplied value by the amount, as a set value. A predetermined amount of odorant can be added to 1a, 1b, 1c, . . . in accordance with the respective gas delivery amounts. Note that, as a specific control method, any appropriate method can be applied as long as it is possible to obtain an addition amount corresponding to the gas delivery amount of each gas delivery system 1, 1a, 1b, 1c, . In addition, in the above case, if the odorant pumps 8, 8' are of positive displacement type,
The sum of the amounts of odorant added to each gas delivery system 1, 1a, 1b, 1c, ... is calculated, and the pump 8,
It is necessary to set the discharge amount of the pump 8' or to keep the discharge amount constant and return the amount other than the required amount to the odorant tank 7 by providing a bypass.
If 8' is a centrifugal type, the discharge amount is determined in balance with the discharge pressure, so these means are not necessary. However, for the pumps 8, 8', any of these systems can be selected as appropriate.

(Effects of the Invention) As described above, the present invention configures an odorant addition system equipped with a control valve and an odorant flow meter in response to multiple gas delivery systems. Since the odorant addition pump system that discharges odorant into the system is configured in common, the number of odorant pumps can be significantly reduced, and an odorant flow meter can be installed in the standby pump system. There is no need to set up
Therefore, the overall configuration can be simplified, and equipment costs and equipment costs can be reduced.
This has the effect of significantly reducing operating costs. Furthermore, the present invention allows the odorant flow meter to be installed near the odorant addition point in each gas delivery system, which prevents odorant from leaking due to check valve leaks, pump or piping troubles, etc. Errors in measuring the flow rate can be minimized, and since the flow rate of the odorant is controlled by a control valve, the odorant can be added more accurately. be.
