Steam-water heat exchange sleeve

Abstract

The invention provides a steam-water heat exchange sleeve which comprises an inner tube and an outer tube. The inner tube is sleeved with the outer tube, the inner tube and the outer tube are coaxially arranged, the thickness of the inner tube wall is twice that of the outer tube wall, the outer tube is supported on the inner tube through five Y-shaped section plates, and the Y-shaped section plates are welded to the inner tube and the outer tube. Hot steam flows in the annular space formed between the inner tube and the outer tube, water flows in the inner tube, and the steam and the water achieves intermediate-wall type heat exchange through the inner tube wall; the outer tube is supported on the inner tube through the five Y-shaped section plates which are welded to the inner tube and the outer tube respectively, the Y-shaped section plates increase heat exchange area, heat of the steam is transmitted into the inner tube through the Y-shaped section plates and the inner tube wall, heat exchange efficiency is improved, heat exchange time is shortened, and it is guaranteed that chemical experiments are performed smoothly.

Description

technical field [0001] The invention relates to a steam-water heat exchange casing. Background technique [0002] Steam-water heat exchange is very common in the heat transfer field. For example, in the heating field and chemical industry, the steam-water heat exchange transfers the heat (latent heat) in the steam to the water. The temperature of the steam decreases and condenses to form condensed water. The water is heated and the temperature rises. for use. In the chemical laboratory, it often occurs that the water temperature is not up to standard due to the low efficiency of the heat exchanger, which leads to the extension of the test time or the failure of the whole experiment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steam-water heat exchange casing, which improves the heat exchange efficiency of steam and water, shortens the heat exchange time, and ensures the smooth progress of the experimen...
