Heating tube with nanometer coating on internal surface and evaporator

Abstract

A heating pipe and evaporator that have the nanometer coat on the inside surface, it comprising: the heating chamber that including some heating pipe, the basic layer of each heating pipe covers the nanometer coat or the sub-nanometer coat, the thickness of the cover is between 20 millimeters to 150 millimeters, the surface of the coat is the floc meshwork structure; the upper pipe box that fix on the top of the heating chamber; the separating chamber, the lower pipe box that fix on the bottom of the heating chamber, the condenser, the incept tank, the regain pump, the vacuum surge-tank, the vacuum-pump. The coat structure of the heating pipe is the super drainable structure, which leads the heat transfer coefficient increase 0.5 times, and the evaporator can operate non-dirtiness a long time.

Description

technical field [0001] The invention relates to a heating tube, in particular to a heating tube with a nano-coating on the surface and an evaporator made of the heating tube. Background technique [0002] The fouling of heat exchangers, especially evaporators, is a technical problem that is generally concerned by industry and academia at present. The fouling of heat exchangers will bring some problems: (1) the heat transfer rate is reduced, and the evaporation capacity is reduced; ( 2) The pressure drop increases, which leads to an increase in power consumption; (3) Frequent parking and cleaning leads to a decrease in productivity. For the scaling phenomenon, although many solutions have been proposed, including physical and chemical cleaning, adding internal components in the device, etc., there are still few satisfactory anti-scaling methods at present. With the development of nanotechnology, its application fields have gradually penetrated into various fields. For exampl...

Problems solved by technology

[0002] The fouling of heat exchangers, especially evaporators, is a technical problem that is generally concerned by industry and academia at present. The fouling of heat exchangers will bring some problems: (1) the heat transfer rate is reduced, and the evaporation capacity is reduced; ( 2) Increased pressure drop, resulting in increased power consumption; (3) Frequent parking and cleaning, resulting in decreased productivity

However, there is no report on the nano-coating on the inner surface of the evaporator heating tube to enhance boiling heat transfer and anti-scaling, and there is no report on the impact of the nano-coating surface structure on improving the heat transfer coefficient and scaling
