Embodiment Construction

[0017] The accompanying drawings describe the structural form of a helical tube and ball all-plastic pressure-bearing double-circulation liner. The liner 1 is made of polymer material, or modified polymer material, or reinforced polymer material, or composite polymer material; there is a reinforcement layer 2 inside the wall of the liner 1, and a plurality of circular trusses or Pyramid-shaped holes 3; the reinforcing layer is spiral, or tubular, or ring-shaped, or reticular, or fiber-dispersed structure; the reinforcing layer is made of metal material, or glass fiber, or carbon fiber, or chemical fiber, or steel fiber, Or ceramic fiber material, or natural fiber material, or plant fiber, or fiber composite material; the reinforcement layer is outside the inner tank wall; the two ends of the inner tank are hemispherical; inner tank 1 and reinforcement layer 2 are integrated blow molding, Or integrated rotational molding, or separate injection molding; the base 21 is made of po...

Abstract

The invention relates to a full-plastic pressure-bearing helical tube ball type dual-circulation liner, which mainly comprises a liner and a heat exchanger. In the heat exchanger of the full-plastic pressure-bearing helical tube ball type dual-circulation liner, a plurality of parallel-connected heat exchange tubes form a circulating channel, the total cross section value of the circulating channel is large, the flowing resistance of a circulating medium is low, thus a naturally-circulating heating working state is formed. The full-plastic pressure-bearing helical tube ball type dual-circulation liner has enough large heat exchange area, thus having small heat resistance and low heat exchange temperature; and scales are difficult to form on the heat exchange surfaces, thus higher heat exchange efficiency can be kept forever. The full-plastic pressure-bearing helical tube ball type dual-circulation liner is manly made of a high polymer material, a modified high polymer material and an enhanced high polymer material, thus a large quantity of metal raw materials can be saved, manufacture cost of the system is greatly reduced; and the full-plastic pressure-bearing helical tube ball type dual-circulation liner has the advantages of long service life, high reliability, simple production process, capability of massive industrialized production, and wide market prospect.

Description

Technical field [0001] The invention relates to a water tank liner, in particular to a helical tube ball type all-plastic pressure-bearing double-circulation liner. Background technique [0002] At present, most of the heat preservation water tanks used for solar water heaters and electric water heaters are made of stainless steel inner tanks. Due to the intergranular corrosion problem in the welds of stainless steel inner tanks, the short service life is an unsolved global problem. Although steel plate enamel inner tanks have been used in recent years at home and abroad However, the processing technology of the enamel liner is high, and air bubbles or pinholes are likely to occur during the production process. At the same time, the enamel is relatively brittle, and vibration and collision are prone to scale explosions. In addition, the enamel will gradually dissolve and peel off in hot water. Technically It is called "boiling water weightlessness" phenomenon, which makes it...
