Tank ventilation system
View Patent ↗A tank ventilation system includes a flushing line, off which a bypass branches and into which the bypass opens out. A sensor is arranged in the flushing line bypass to determine a concentration of hydrocarbons in a fluid in the flushing line. A hydrocarbon tank is coupled via a first connector to a first end of the flushing line and designed for coupling, via a second coupling, to a tank.
1. A tank ventilation system, comprising:
a purge line, off which a first end of a bypass line branches at a branch off and into which a second end of the bypass line opens downstream of the branch off, wherein the bypass line has only one input, the only one input arranged at the first end of the bypass line and only one output arranged at the second end of the bypass line opposite the first end of the bypass line;
a sensor, arranged in the bypass line and configured to determine a concentration of hydrocarbons in a fluid in the purge line; and
a hydrocarbon storage device having a first and a second connection, the first connection coupled to a first end of the purge line, the second connection configured for connection to a tank.
2. The tank ventilation system as claimed in claim 1 , in which the bypass line is U-shaped.
3. The tank ventilation system as claimed claim 2 , wherein the purge line comprises a valve arranged at the second end of the purge line opposite the first end of the purge line.
4. The tank ventilation system as claimed claim 1 , wherein the purge line comprises a valve arranged at the second end of the purge line opposite the first end of the purge line.
5. The tank ventilation system as claimed claim 4 , wherein the sensor is arranged in a housing.
6. The tank ventilation system as claimed claim 5 , wherein the sensor is connected to at least one electrical contact arranged in the housing.
