Abstract
Description
Technical Field
[0001] The invention relates to the technical field of vanadium metallurgy, in particular to a zero-leakage water-cooled inner spiral. Background Art
[0002] At present, the widely used technical solution in the industry is the online water-cooled internal spiral system. This system occupies an important position in many industrial cooling scenarios due to its efficient heat conduction capability and compact structural design. However, with the deepening of technical application and the improvement of refined requirements, its inherent limitations are becoming increasingly prominent. Specifically, the existing water-cooled internal spiral system has two significant design defects: First, there is a lack of a pressure differential control valve at the water inlet end, which makes it impossible to accurately adjust and stably control the water inlet pressure, thereby affecting the uniformity and stability of the water flow distribution in the entire cooling circulation system; second, there is no flow control valve installed at the water outlet, which makes it impossible to flexibly adjust the reflux speed and flow of the circulating cooling water, further exacerbating the complexity of the fluid dynamics within the system and reducing the overall efficiency.
[0003] The pressure difference between the inlet and return water of the circulating cooling water is one of the key indicators to measure the performance of the circulation system. Its stability is directly related to the smoothness of the system operation and the efficiency of heat exchange. The instability of the pressure difference may not only lead to uneven water flow distribution, causing local overheating or overcooling, affecting the normal operation and service life of the equipment, but also reduce the heat exchange efficiency and increase energy consumption. In addition, the lack of an effective flow regulation mechanism also makes it difficult for the system to respond quickly and make optimization adjustments when facing different working conditions.
[0004] In order to fundamentally solve the above technical problems and improve the comprehensive performance of the water-cooled inner spiral system, an innovative zero-leakage water-cooled inner spiral design is proposed. Summary of the invention

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.
