Centralized curing device and curing method for carbon-fiber-wound hydrogen storage tanks

Abstract

The invention discloses a centralized curing device and curing method for carbon-fiber-wound hydrogen storage tanks. The curing device comprises a rack platform and a platform cover cap, wherein the plurality of carbon-fiber-wound hydrogen storage tanks are vertically installed on the rack platform, a vertical sheath is arranged on the periphery of each carbon-fiber-wound hydrogen storage tank, a first corrugated pipe is connected to an upper end orifice of each vertical sheath, and a second corrugated pipe is arranged at the lower end of the platform cover cap; a hot air supply cavity is formed in the upper portion of the platform cover cap, a hot air recovery cavity is formed in the lower portion of the rack platform, a first hot air distribution hole and a second hot air distribution hole are formed in the platform cover cap separately, and a first hot air recovery hole and a second hot air recovery hole are formed in the rack platform separately; and a hot air circulation pipeline is connected between the hot air recovery cavity and the hot air supply cavity, and a fan and an air heater are arranged on the hot air circulation pipeline separately. According to the invention, the energy consumption of curing operation is reduced, and the heating and curing performance, quality and reliability of carbon-fiber-wound layers are improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing carbon fiber winding hydrogen storage tanks, in particular to a centralized curing device and curing method for carbon fiber winding hydrogen storage tanks. Background technique [0002] The high-pressure hydrogen storage bottle has the advantages of simple structure of hydrogen storage container, less energy consumption for preparation of compressed hydrogen, fast filling speed, etc., and has become the main method of hydrogen energy storage and transportation. At present, there are more high-pressure hydrogen storage tanks with composite liners and carbon fiber fully wound high-pressure hydrogen storage tanks, which use metal (commonly used as aluminum alloy or carbon steel) or plastic as the inner tank, and outside the metal inner tank or plastic inner tank. Wind a layer of carbon fiber impregnated with epoxy resin glue, and form a carbon fiber winding layer after curing. The high-pressu...

AI Technical Summary

Problems solved by technology

[0005] First, the space utilization rate of the curing room is low, the amount of hot air is large, the heat loss is large, and the energy consumption is high

[0006] The second is that the uniformity of hot air circulation in the curing room is poor, which affects the quality and reliability of the heating and curing of the carbon fiber winding layer

[0007] The third is that the precipitation of internal gas is not sufficient during the curing process, resulting in a certain void ratio inside the carbon fiber winding layer, which reduces the performance of the carbon fiber winding layer to a certain extent
