Spray piping is connected, and connection shaft not only acts as connection effect, more plays a supporting role to spray piping；The spray piping
Underface is uniformly distributed multiple spray heads, gasification materiel and liquefied mass when the setting of spray equipment can effectively increase spray herein
Contact area, when pressure is excessive in shell, solenoid valve is opened, and spray equipment, which is started to work, can be achieved to spray within a short period of time
The purpose of decompression.
Preferably, the spray piping can be endless track shape, more fitting tank interior, when spray can effectively with
Gasification materiel comes into full contact with.
Preferably, the spray head on the outermost layer spray piping is obliquely installed to inner walls direction, and tilt angle is
15 ° -60 °, the area that the increase gasification materiel at comprehensive no dead angle is contacted with spray material maximumlly plays spray equipment
Effect.
The utility model reached it is following the utility model has the advantages that
1, the generation for effectively reducing lamination in tank prevents liquid gasification in LNG storage tank, and pressure increases, and generates dangerous.
2, it is provided with the second outlet tube road, prevents external outlet tube from damaging, interior material is managed and is unable to normal use, cause inconvenient maintenance.3,
Structure is simple, easy to use, not only can adequately use the intracorporal liquid of tank, also eliminate the manpower safeguarded repeatedly and when
Between, the globality of inner canister is more preferable, and integral strength is higher.
