Liquefied natural gas tank car unloading device of liquefied natural gas and compressed natural gas cooperative station and application

The invention discloses a liquefied natural gas tank car unloading device of a liquefied natural gas and compressed natural gas cooperative station and application. According to the liquefied natural gas tank car unloading device of the liquefied natural gas and compressed natural gas cooperative station, one end of a CNG main pipeline (17) is connected with a first hose (2), and the other end of the CNG main pipeline (17) is connected with a first stop valve (3), a reducing valve (5), a first check valve (8) and a second hose (14) in sequence. A gas phase outlet of an LNG storage tank (11) is connected with a low-temperature gas inlet of a heat exchanger (6) through a second stop valve (10). A low-temperature gas outlet of the heat exchanger (6) is connected with an inlet of a temperature controller (7). An outlet of the temperature controller (7) is connected with an inlet of a compressor (4). An outlet of the compressor (4) is connected with a gas inlet of the heat exchanger (6). One end of an LNG storage tank inlet pipeline (18) is connected with an inlet of the LNG storage tank (11) through a third check valve (13) and a third stop valve (12) in sequence, and the other end of the LNG storage tank inlet pipeline (18) is connected with a third hose (15). The liquefied natural gas tank car unloading device has the beneficial effects that the LNG gasification rate can be lowered, waste is avoided, and LNG tank car unloading is convenient.
