Low-temperature tank truck

Abstract

The invention relates to a low-temperature tank truck. The low-temperature tank truck comprises a storage tank, a vaporizer and a defrosting unit; the vaporizer communicates with the storage tank; thedefrosting unit comprises a high-pressure gas source, a connecting pipe, a control valve and a blowing pipe the high-pressure gas source, the connecting pipe and the blowing pipe sequentially communicate; the control valve is arranged on the connecting pipe; and the blowing pipe is arranged close to the vaporizer, and a plurality of gas flow holes are formed in the blowing pipe and face the vaporizer. According to the tank truck, the defrosting unit is additionally arranged on the vaporizer of the tank truck; the blowing pipe is arranged close to the vaporizer and matched with the gas flow holes in the blowing pipe, and the defrosting operation is conducted on the vaporizer through high-pressure gas provided by the high-pressure gas source; and when the surface of the vaporizer frosts dueto long-time work, the control valve can be opened to enable the high-pressure gas in the high-pressure gas source to be blown to the vaporizer at a high speed through the gas flow holes, so that frost covering the surface of the vaporizer is blown off, the function of defrosting the vaporizer is achieved, and the vaporization effect of the vaporizer is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of industrial tank cars, in particular to a low-temperature tank car. Background technique [0002] Industrial gases (oxygen, nitrogen, argon, etc.) are regarded as the "blood" of industry, and their important status and role in the national economy have become increasingly prominent. As the downstream application fields of the industrial gas industry continue to expand, the demand for industrial gases continues to grow. In order to meet the requirements of customers with multiple locations, long distances, and large quantities, the demand for low-temperature industrial gas tankers as professional transportation equipment has grown steadily. [0003] After the low-temperature industrial gas tanker is fully loaded with medium and transported to the destination, a small amount of liquid in the tanker is vaporized into gas through the built-in vaporizer and circulated into the tanker to increase the pressure i...

AI Technical Summary

Problems solved by technology

[0004] In the related technology, due to the limited space of the tank car, the supporting vaporizer is generally small in size. After the vaporizer vaporizes the liquid in the tank into gas for a long time, a large area of ​​frost will form on the surface, resulting in a decrease in the vaporization efficiency of the liquid and a decrease in the pressurization rate. As a result, the unloading rate of the tank car is reduced, and the unloading time of the whole vehicle is greatly extended

Even when the carburetor is severely frosted, the carburetor cannot work and the tanker cannot unload liquid

The frosting phenomenon of the carburetor has a great influence on the working efficiency of the vehicle unloading fluid
