Efficient all-weather air temperature vaporizer

Abstract

The invention relates to an efficient all-weather air temperature vaporizer. The efficient all-weather air temperature vaporizer comprises spiral multiplies arranged in a finned tube in the axis direction, so that spiral flow guide channels are formed in the finned tube, low-temperature mediums spirally flow along the multipliers, and the positions of the low-temperature mediums in the center of the finned tube and the positions of the low-temperature mediums around the inner wall of the finned tube are continuously and alternately changed. The heat exchange of the low-temperature mediums is more uniform, the flowing time in the finned tube is longer, the vaporization efficiency is high, the environmental temperature is utilized to the maximum extent, and energy conservation and environmental protection are realized; meanwhile, electric heating rods penetrating through the multipliers are arranged in the finned tube to directly heat and vaporize the low-temperature mediums, heat is transmitted to the multipliers and the finned tube to further heat and vaporize the low-temperature mediums flowing through the multipliers, heat generated by the electric heating rods is completely sealed in the finned tube, no loss is caused, and vaporization efficiency is extremely high; and finally, the temperature of output gas can be controlled according to needs, the use is more flexible, andthe universality is high.

Description

technical field [0001] The invention belongs to the technical field of vaporizers, in particular to an efficient all-weather air-temperature vaporizer. Background technique [0002] At present, the air-temperature vaporizer does not need electricity or fuel, and only relies on the heat sink of the vaporizer to absorb air heat energy to heat the low-temperature medium (low-temperature liquid / gas) from minus 196°C (for liquid nitrogen) to normal temperature gas, so it is especially important in the petrochemical field. It is widely used in the natural gas industry. [0003] However, the applicant found that: in the existing air-temperature vaporizers on the market, the fins absorb the heat in the air and then transfer the heat to the finned tubes, and the finned tubes then transfer the heat to the low-temperature medium in the tubes, so as to gradually heat the low-temperature medium purpose. In this heat transfer process, the low-temperature medium flows in a straight line ...

Problems solved by technology

In this way, an additional heating system needs to be provided, and this heating system transfers heat energy to the low-temperature medium through another medium, which will inevitably cause energy conversion loss and low heating efficiency

[0006] In addition, in order to improve the heat exchange efficiency, the existing air-temperature vaporizer often needs to increase the heat exchange fin area, which makes the volume of the vaporizer too large; at the same time, the gas temperature at the outlet end of the traditional air-temperature vaporizer cannot be controlled in real time, and the output gas temperature cannot be guaranteed to reach the level of the equipment. requirements, there are certain security risks
