LNG ambient air temperature vaporizer star-finned heat pipe has eight-fin symmetry, and the material option is LF21 aluminum alloy, which is corrosion-resistant, weather-resistant, and vaporizes well. The material of the liquid and gas guide tube is T2M copper tube, which is resistant to high pressure and impact. The base and bracket material options are angled LF21 rust-resistant aluminum alloy, which is corrosion-resistant.
Precautions:
1. The installation site must have good ventilation conditions, keep away from high-voltage sources, grease fire sources, and keep the ground clean.
2. The installation site must have a safety exit, and there are safety signs around it.
3. The installation site should provide its own fire fighting equipment.
4. It is generally installed outdoors, and it must be equipped with a grounding device that guides and eliminates static electricity and an anti-lightning device.
5. Its ambient temperature is -20 - +50, generally 200m/h in the south and 400m/h in the north.
6. The staff should operate in accordance with the JB6898-1997 regulations.
The built-in liquid-absorbing core used in the LNG ambient air temperature vaporizer is a stainless steel belt, which is wound into a cylindrical shape and then attached to the air wall of the finned tube. When the heat-absorbing core is immersed in liquefied petroleum gas or natural gas liquid, due to the liquid surface tension capillary The liquid in the liquid film is adsorbed in the narrow gap between the liquid-absorbing core and the inner wall of the finned tube, and the finned tube absorbs heat and vaporizes to form tiny bubbles. When the tiny bubbles flow upward and form relatively air bubbles, the suction The small holes on the upper surface of the liquid core escape, the liquid surface breaks away into gas and boils, and after the tiny bubbles leave the liquid-absorbing core, the liquid is replenished into the gap by the small holes on the liquid-absorbing core to form micro-convection heat transfer and due to the built-in liquid-absorbing core The liquid is separated from the spiral guide belt, so as not to be carried by the latter and leave the finned tube prematurely, which is beneficial to the generation of tiny air bubbles.
