Abstract

The invention relates to a precooling device, in particular to a storage tank precooling device for a liquefied natural gas filling station. The technical problem of the invention is to provide the storage tank precooling device for the liquefied natural gas filling station, which can be used for quickly precooling a storage tank. According to the technical scheme, the storage tank precooling device for the liquefied natural gas filling station comprises a first fixing plate, a supporting base and a liquid nitrogen box, the supporting base is arranged on one side of the top of the first fixing plate, and the liquid nitrogen box is placed on the side, away from the supporting base, of the top of the first fixing plate. And the top ball and the movable plate are matched with each other to form two protections to block the second liquid conveying pipe, so that the liquid nitrogen in the liquid nitrogen tank is prevented from leaking out through the first liquid conveying pipe and the second liquid conveying pipe when the pre-cooling work is not carried out.

Description

technical field [0001] The invention relates to a precooling device, in particular to a storage tank precooling device used in a liquefied natural gas filling station. Background technique [0002] With the gradual maturity of new energy technology, many cars are gradually using compressed natural gas and liquefied natural gas as fuel. When it is necessary to add liquefied natural gas to the car, it will be added to the filling station. The liquefied natural gas at the filling station is usually It is stored in the storage tank. Before the liquefied natural gas is fed into the storage tank, it is necessary to pre-cool the storage tank so that the storage tank can start to be fed with liquefied natural gas. At present, the pre-cooling of the storage tank is carried out by placing the storage tank in a refrigerator Precooling, but the precooling time required by this method is longer, which will affect the subsequent work of feeding liquefied natural gas and affect work effici...
