FIELD: oil and gas production. ^ SUBSTANCE: invention refers to gas industry. The object of the invention is met like follows: the odouriser of module type contains odourising tanks of storage, service and measuring, a dozing pump, a measuring unit for odorant consumption, a respiratory filter, a sensor-indicator of odorant level, a socket-outlet to a pipeline with gas, a pressurising pipeline, a unit of odorant inlet into gas flow, and a control unit in an explosion-proof case. Also the odouriser is equipped with a vacuum indicator, with an electromagnetic valve included into the unit for odourant consumption measuring, with a differential pressure indicator, with a vacuumising pipeline and a drainage pipeline. The vacuumising pipeline consists of an inlet into the service tank, of in inlet to the measuring tank, of a vacuum sensor, and of two locking elements of the pipeline. The drainage pipeline is equipped with three locking pipeline elements, one of which is connected with the inlet of the dozing pump, the second element is connected with the pressurising pipeline and the third one is connected with the odorant storage tank. The electro-magnetic valve and the locking element are installed in the circuit of the feeding pipeline; also the locking element is connected with the odourant measuring tank and with the detector of differential pressure. ^ EFFECT: object of invention is facilitation of stable operation and increased reliability of odouriser. ^ 6 cl, 1 dwg |
