Description
Technical Field
The utility model discloses be applied to cryrogenic low temperature liquefied gas storage and transportation and equip the field, be applicable to a turbocharging system on the low temperature car.
Background
LNG carriers are becoming more and more widely used with the hot development in the LNG market. The low temperature car needs the pressure in the transport vechicle jar to be greater than the pressure of storage tank at the liquid in-process of unloading, just can be smooth quick unload liquid, and this just needs to use the turbocharging system to carry out the pressure boost to the low temperature car. At present, the liquid is unloaded by adopting an external pressurization mode, namely, the tank car is pressurized from the outside during the liquid unloading so as to achieve the purpose of liquid unloading, the liquid unloading mode can only be used for unloading liquid at a fixed station, the construction requirement cost of the station is higher, relevant pipelines need to be connected on site during the liquid unloading, the working flow is increased, and uncertain factors such as operation errors of operators exist.
Disclosure of Invention
The technical problem solved by the invention is as follows: a set of pressurization system is added in the limited space of the liquefied gas transport vehicle to meet the requirement of rapid liquid discharge of the low-temperature tank wagon at any time and any place.
The technical idea adopted by the invention is as follows:
the back pipeline of the liquefied gas carrier vehicle is connected with a pressure inlet check valve at a pressure inlet, and then connected with a control valve at a pressure inlet, and is connected with a liquid inlet of the pressure booster through a stainless steel hose and a flange, and an outlet of the pressure booster is connected with a pressure outlet control valve through a flange and a stainless steel hose and is connected with a gas phase port of the back pipeline of the low temperature vehicle. The supercharger is arranged on the side surface of the low-temperature vehicle.
The technical scheme adopted by the invention is as follows: the supercharging system comprises a supercharger, a supercharger inlet and outlet control stop valve, a supercharging port check valve, a stainless steel hose, a stainless steel pipe, a connecting flange and a supporting device.
Further, the pressurizing system and the liquid inlet of the pressurizer are connected with the pressurizing port control valve through a stainless steel hose and a flange and are connected to the pressurizing port of the liquefied natural gas carrier vehicle pipeline through a liquid inlet check valve.
Furthermore, the outlet of the booster of the pressurization system is connected with the control valve of the pressurization outlet through a stainless steel hose and a flange and is connected to a gas phase port of a back pipeline for transporting the liquefied natural gas.
Furthermore, a pipeline of the pressurization system is led out from the rear operation pipeline of the tank body to the rear side of the tank body, and the pressurizer is arranged at a groove between the side tire of the liquefied gas carrier vehicle and the tank body and is fixed on a chassis longitudinal beam of the carrier vehicle through a supporting device.
The technical progress achieved by the invention is as follows:
the utility model provides a low temperature car is from turbocharging system in area. Compared with an independent pressurization system, the liquid discharging device has the advantages that the liquid discharging device is not limited by places and can discharge liquid at any time and any place. And the pressurizing structure is led out from the rear pipeline of the tank body and is arranged on the side surface of the low-temperature vehicle, so that the installation and the operation are convenient. The booster is composed of two disconnected finned tubes inside and outside, is arranged at a groove between a tire and a tank body, and utilizes the position of the lower part of the side of the tank body to the maximum extent to maximize the vaporization amount of the finned tubes so as to realize quick liquid discharge.

Detailed Description
The supercharging system comprises a supercharger 1, a supercharger 2, a supercharger inlet control stop valve, a supercharger outlet control stop valve 3, a supercharger outlet check valve 4, a supercharging port check valve 5, a stainless steel hose 6, a stainless steel pipe 7, a connecting flange and a support 8.
As shown in fig. 1 and 2, a supercharger 1 of the supercharging system is mounted on a side surface of a low-temperature vehicle. The tank body pressurization port is connected with a pressurization port check valve 4 through a stainless steel pipe 6, wound to the side face of the operation box, penetrates through the tank body and then is connected with a supercharger inlet control stop valve 2, and is connected with a supercharger inlet through a connecting flange 7 and a stainless steel hose 5. The outlet of the booster is connected with the outlet control valve of the booster through a stainless steel hose 5 and a connecting flange and returns to the gas phase port of the tank body through a stainless steel pipe 6, thereby forming a boosting loop. The supercharger 1 is fixed on a chassis beam of the low-temperature vehicle through a support 8.
When liquid is unloaded in the pressure boost, open booster import control stop valve 2, booster export control stop valve 3, liquid gets into booster 1 by the booster import in the jar, fully gasifies through booster 1, and the gaseous phase space of getting back to the jar body through the booster export of after-gasification makes the pressure increase in the jar for the speed that the liquid was unloaded to the low temperature car.
A stainless steel hose 5 is connected between the supercharger 1 and the rear pipeline, and the position is convenient to finely adjust in the process of installing the supercharger 1. The supercharger 1 is arranged on the side face of the low-temperature tank car, the side face position is fully utilized, the length of the supercharger finned tube is increased as much as possible, the vaporization amount is maximized, liquid discharging is faster, and the installation of the side face supercharger is more convenient.
The supercharger 1 is composed of two disconnected finned tubes inside and outside, and the position of the lower part of the side of the tank body can be utilized to the maximum extent, so that the evaporation amount of the finned tubes is maximum.
