Heat exchanger with nonmetal heat exchange tube bundle

Abstract

The invention discloses a heat exchanger with a nonmetal heat exchange tube bundle. The heat exchanger comprises a front tube box, a rear tube box, the nonmetal heat exchange tube bundle and a housing, wherein the nonmetal heat exchange tube bundle is mounted in the housing; supports are arranged at the lower part of the housing; a second fluid outlet and a second fluid inlet are formed in the housing; the two ends of the housing are connected with the front tube box and the rear tube box by flanges respectively; a front tube plate and a rear tube plate of the nonmetal heat exchange tube bundle are clamped by the flanges, the front tube box and the rear tube box that are connected with the two end parts of the housing respectively; sealing gaskets are arranged between contact surfaces; a partition plate is arranged in the front tube box; a first fluid inlet is formed in the upper part of the front tube box; a first fluid outlet is formed in the lower part of the front tube box; and the partition plate is arranged between two adjacent nonmetal heat exchange tubes. By virtue of the technical scheme, the heat exchanger is corrosion-resistant, realizes the effect of long-period stable operation, has the advantages of tightness in sealing and high pressure bearing capacity, is applicable to air-liquid heat exchange occasions, and is simple in structure and low in manufacturing cost, and the overall manufacturing automation and mass production of the heat exchanger can be realized easily.

Description

technical field [0001] The invention relates to a heat exchanger with non-metallic heat exchange tube bundles, in particular to a heat exchanger with non-metallic heat exchange tube bundles that can be used in heat exchange conditions with strong corrosive media and a certain pressure . Background technique [0002] In the presence of some strong corrosive media, such as low-concentration sulfuric acid and heat exchangers containing solutions with high chloride ion concentrations, due to corrosion, a large number of corrosion-resistant precious metals, such as titanium, nickel-based alloys, and zirconium, are used. These materials have excellent corrosion resistance, but are extremely expensive, which limits their applications. Non-metallic heat exchange tubes have been widely used due to their excellent corrosion resistance and low price. However, due to the characteristics of non-metallic materials, it is difficult to connect them with metals and similar materials, thus l...
