Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] A low-temperature liquid vaporization device mainly consists of a low-temperature pressure liquid Dewar tank 1, a vaporization chamber 4, and a pressure gas tank 5. The low-temperature pressure liquid Dewar tank 1, the vaporization chamber 4, and the pressure gas tank 5 are connected by pipelines. A flow valve 2 and a pressure feedback valve 3 are installed on the connecting pipeline between the low-temperature pressure liquid Dewar tank 1 and the vaporization chamber 4. The low-temperature pressure liquid Dewar tank 1 is provided with a pipeline connected with the pressure gas tank 5. The shut-off valve 8 and the pressure gas tank 5 are connected to the working unit through a pipeline, and the shut-off valve 6 is installed on the pipeline. The low-temperature pressure liquid Dewar tank 1, the vaporization chamber 4 and the pressure gas tank 5 are connected thro...

The invention discloses a vaporizing unit for cryogenic liquid and mainly consists of a dewar tank of cryogenic and low pressure liquid (1), a vaporizing chamber (4) and a pressure air tank (5); wherein, the cryogenic and low pressure liquid (1), the vaporizing chamber (4) and the pressure air tank (5) are connected with each other by a pipeline; a flow valve (2) and a pressure feedback valve (3)are arranged on the connecting pipeline of the cryogenic and low pressure liquid (1) and the vaporizing chamber (4); a stop valve (8) is arranged on the connecting pipeline of the cryogenic and low pressure liquid (1) and the pressure air tank (5); the pressure air tank (5) is connected with working units by the pipeline which is provided with a stop valve (6). The device has the advantages of simple structure, reliable operation and convenient maintenance; besides, the device can transform cryogenic liquid into gas under normal temperature, thereby providing imperative vaporizing units for the commercial process of the vaporizing unit for cryogenic liquid. The invention also has the advantages of low production cost and wide market prospect.
Description
technical field [0001] The invention relates to a vaporization device for converting low-temperature liquid into pressure gas. Background technique [0002] With the environmental pollution and the shortage of oil resources, society's demand for clean energy is increasing day by day. As a pollution-free energy source, air is favored by people, but the storage volume of air is large, which is not conducive to its application in industrial production. The present invention uses the principle that the volume of the liquid state is much smaller than that of the gaseous state, so that it is easy to store, and converts oxygen and nitrogen into liquid at a low temperature of -200°C. In application, it is converted into pressure gas by a vaporization device to generate a power source. Due to many technical difficulties in the production of cryogenic liquid vaporizers still in the experimental stage, there is no corresponding vaporizer that can be used to vaporize cryogenic liquids....
