Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of enamel heat exchanger, specifically to an enamel disc and pipe coil heat exchanger. BACKGROUND
[0002] The enamel disc heat exchanger is widely used in high-efficiency heat exchange occasions in chemical reactions such as petroleum chemical industry, fine chemical, pesticide, dye and medicine. Its working principle is to convert gas or steam into liquid or gas through cooling medium such as frozen brine, circulating water and heat-conducting oil, and rapidly cool or heat the medium in the enamel contact surface part of the container to the appropriate working condition, so as to realize the condensation and heating process.
[0003] The existing products on the market have the following shortcomings: 1. Large material resistance, leading to uneven distribution of medium and easy to produce deflection. 2. Poor cooling effect, single jacket cavity is too small and has no flow guide measure, leading to direct overflow of medium from the inlet to the outlet without circulating in the cavity. It cannot realize rapid cooling and needs to increase the heat exchange area to realize cooling. 3. Design defects, because the structure adopts the form of superimposed combination between the sheets, the gap between the two sheets is sealed by the gasket. The height of the gasket determines the gap between the two sheets of the equipment. The thicker the gasket, the larger the gap between the two sheets. This leads to the formation of laminar flow of material between the enamel surfaces, which cannot realize heat transfer in time. The thinner the gasket, the softer it is under high pressure and high temperature reaction, which leads to the failure of the sealing surface and the generation of leakage points. When the external bolt fastener is tightened to the critical point, the upper and lower enamel surfaces are tightly closed together, which leads to the damage of the enamel surface and the failure of the equipment. Under negative pressure conditions such as-0.35Mpa vacuum, the gasket deforms without backstop device, which leads to the expansion and contraction of the gasket part into the container, thus causing leakage. Serious leakage may cause overflow of the medium in the container and easily cause safety accidents. UTILITY MODEL CONTENTS
