Problems solved by technology

Cryogenic liquid gas pressurization can only be carried out when the vehicle is fixed. As long as the vehicle shakes, the pressure will drop to the original pressure of the vehicle, so each pressurization needs to be boosted from the original to the highest pressure. Unloading, the gas phase space is getting bigger and bigger, and the pressurization speed is getting slower and slower, which cannot meet the requirements of multiple unloading, and the distribution efficiency is low

Embodiment 1

[0028] Such as figure 1 As shown, the present invention discloses a vehicle tank body, wherein the vehicle tank body includes a tank body body 1, a partition plate 2, a switch device and a supercharger.

[0029] The number of partitions 2 is multiple, and the plurality of partitions 2 are arranged in the tank body 1 to divide the tank body 1 into a first preset compartment 3 . It should be noted that the number of cabins 3 can be set according to actual needs.

[0030] The switch device is installed between the multiple compartments 3 , that is, the switch device can be installed between any two compartments 3 of the multiple compartments 3 , and the switch device can connect or close each compartment 3 .

[0031] The pressure booster can pressurize the gas in the tank main body 1 .

[0032] In the vehicle tank body disclosed by the present invention, a plurality of partitions 2 divide the vehicle tank body into a first preset cabin 3, and when in use, each cabin 3 can be cl...

Embodiment 2

[0034] In the second embodiment provided by the present invention, the vehicle tank body in this embodiment is similar in structure to the vehicle tank body in Embodiment 1, and the similarities will not be repeated, and only the differences will be introduced.

[0035] In this embodiment, it is specifically disclosed that the switch device is a valve. It should be noted that the switch device may also be other devices capable of closing or opening each compartment 3 .

[0036] Further, the present invention discloses that the number of superchargers is the same as the number of chambers 3 , and each supercharger communicates with one chamber 3 . That is, each compartment 3 is equipped with a separate supercharger, which can realize real-time pressurization of each compartment 3 .

[0037] In this embodiment, the number of cabins 3 is three as an example.

[0038] The present invention has the following advantages:

[0039] (1) It can be pressurized separately after subdivis...

Embodiment 3

[0042] In the third embodiment provided by the present invention, the vehicle tank body in this embodiment is similar in structure to the vehicle tank body in Embodiment 2, and the similarities will not be repeated, and only the differences will be introduced.

[0043] In this embodiment, it is specifically disclosed that the number of superchargers is one, and the superchargers communicate with the first preset compartments 3 respectively. That is to say, the cabins 3 are arranged in parallel with each other, and are pressurized by the same supercharger at the same time.

Abstract

The invention discloses a vehicle tank. The vehicle tank comprises a tank main body, a plurality of partition plates, switch devices and a supercharger, wherein the partition plates are used for dividing the tank main body into a first preset number of cabins; the switch devices are mounted among the cabins, and can communicate with the cabins or can close the cabins; and the supercharger can supercharge gas in the tank main body. In use, each chamber can be closed by the switch devices, so that each chamber is an independent unit; during unloading, one cabin can be supercharged and unloaded through the supercharger; and single cabin is smaller than the volume of the vehicle tank, and therefore, time needed for single-time supercharging is short, supercharging efficiency is high and distributing efficiency is also high. When liquid in one cabin is used out, gas-phase pressure can be kept; and during next-time supercharging, the liquid is guided into another cabin, so that superchargingtime is shortened, and distributing efficiency is high. Tank body supercharging speed of the tank car is increased, and LNG distributing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of liquefied natural gas transportation equipment, in particular to a vehicle tank body and a tank car. Background technique [0002] With the widespread application of LNG (liquefied natural gas), the number of LNG customers is increasing. Small customers have increased significantly, and small customers use less LNG but have a large base. [0003] The existing low-temperature tank car has only one tank body. Cryogenic liquid gas pressurization can only be carried out when the vehicle is fixed. As long as the vehicle shakes, the pressure will drop to the original pressure of the vehicle, so each pressurization needs to be boosted from the original to the highest pressure. For unloading, the gas phase space is getting bigger and bigger, and the pressurization speed is getting slower and slower, which cannot meet the requirements of multiple unloading, and the distribution efficiency is low. [0004] There...
