At present, a storage tank for storing liquefied natural gas in the petrochemical industry comprises a horizontally arranged outer tank body, and feet are symmetrically arranged at the bottoms of two ends of the outer tank body. An inner tank body is concentrically arranged in the outer tank body, a gap is reserved between the inner tank body and the outer tank body, and supporting rods are arranged between the two ends of the inner tank body and the inner wall of the outer tank body. The lower part of the one end of the inner tank body is provided with a first discharge pipe, one end of the first discharge pipe extends into the bottom of the inner tank body, the other end of the first discharge pipe penetrates through the outer tank body to extend outside, a discharge pump is arranged on the section of the first discharge pipe located in the inner tank body, and a first stop valve is arranged at the extending end of the first discharge pipe. In the use process of the storage tank, once the discharge pump is damaged, the stored liquefied natural gas cannot be discharged, and when the storage tank is opened for maintenance, the stored liquid can only be gasified and discharged into the air, so that energy is wasted.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a storage tank with reserve discharge mechanism, but adopt this storage tank energy saving.
In order to solve the problems, the following technical scheme is provided:
the utility model discloses a storage tank with reserve discharge mechanism includes the outer jar of body of horizontal arrangement, and the bottom symmetry at outer jar of body both ends is provided with the lower margin. An inner tank body is concentrically arranged in the outer tank body, a gap is reserved between the inner tank body and the outer tank body, and supporting rods are arranged between the two ends of the inner tank body and the inner wall of the outer tank body. The lower part of the one end of the inner tank body is provided with a first discharge pipe, one end of the first discharge pipe extends into the bottom of the inner tank body, the other end of the first discharge pipe penetrates through the outer tank body to extend outside, a discharge pump is arranged on the section of the first discharge pipe located in the inner tank body, and a first stop valve is arranged at the extending end of the first discharge pipe. The device is characterized in that a groove which is longitudinally arranged along the inner tank body is formed in the bottom of the inner tank body, a standby pump is arranged in the groove, the outlet of the standby pump is connected with a second discharging pipe, the upper end of the second discharging pipe sequentially penetrates through the inner tank body and the outer tank body to extend out, and a second stop valve is arranged at the extending end of the second discharging pipe.
Wherein, the section of second discharging pipe outer wall that is arranged in outer jar body and the inner tank body coats and is stamped the heat preservation.
The groove bottom of the groove is obliquely arranged towards one end of the groove, and the standby pump is positioned in one end of the groove with low height.
By adopting the scheme, the method has the following advantages:
because the utility model discloses an inner tank body bottom of storage tank with reserve discharge mechanism has along its longitudinal arrangement's recess, has the stand-by pump in the recess, and the exit linkage of stand-by pump has the second discharging pipe, and the upper end of second discharging pipe passes the inner tank body in proper order and stretches out outside with outer jar of body, and the overhanging of second discharging pipe is served and is had the second stop valve. When the discharge pump breaks down, the second stop valve can be opened, the standby pump is started to discharge the liquefied natural gas in the inner tank body, and liquid is not gasified and discharged into the air when the tank is opened for maintenance, so that energy is saved.
Drawings
Fig. 1 is a schematic structural diagram of a storage tank with a spare discharging mechanism according to the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1, the utility model discloses a storage tank with reserve discharge mechanism includes the outer jar of body 1 of horizontal arrangement, and the bottom symmetry at the outer jar of body 1 both ends is provided with lower margin 11. An inner tank body 2 is concentrically arranged in the outer tank body 1, a gap is reserved between the inner tank body 2 and the outer tank body 1, and supporting rods 5 are arranged between the two ends of the inner tank body 2 and the inner wall of the outer tank body 1. The lower part of the one end of the inner tank body 2 is provided with a first discharging pipe 8, one end of the first discharging pipe 8 extends into the bottom of the inner tank body 2, the other end of the first discharging pipe 8 penetrates through the outer tank body 1 to extend out, a discharging pump 9 is arranged on the section of the first discharging pipe 8 in the inner tank body 2, and a first stop valve 7 is arranged at the extending end of the first discharging pipe 8. The device is characterized in that a groove 12 is formed in the bottom of the inner tank body 2 and longitudinally arranged along the inner tank body, a standby pump 10 is arranged in the groove 12, an outlet of the standby pump 10 is connected with a second discharge pipe 3, the upper end of the second discharge pipe 3 sequentially penetrates through the inner tank body 2 and the outer tank body 1 to extend out, and a second stop valve 4 is arranged at the extending end of the second discharge pipe 3.
