It has the advantages of simple structure, durable, low cost, wide application, convenient cleaning, and strong adaptability. It is a commonly used chemical or heating mechanical equipment. For heat exchange in chemical production processes or urban heating. The structure of the existing tube-and-tube heat exchanger mainly includes a shell, which is provided with a heat exchange tube bundle, and tube plates are installed at both ends of the heat exchange tube bundle, and the two ends of the shell are respectively provided with a head, and the seal The head is connected to the tube sheet, the tube side of the heat exchange tube bundle is provided with a baffle plate, the heads at both ends of the shell are respectively provided with a medium I inlet and a medium I outlet, and the upper and lower parts of the shell are respectively provided with The inlet of medium II and the outlet of medium II, the heat exchange tube bundle generally adopts heat exchange tubes of equal diameter, and the material of heat exchange tubes is mostly made of carbon steel. The problems of this tube-and-tube heat exchanger are: 1. The flow rate of the working medium is small 2. When the working medium is corrosive, the heat exchange tube made of carbon steel cannot adapt to the work. Environmental needs.
实用新型内容 Utility model content
本实用新型要解决的技术问题是提供一种换热效率高、并且能够在具有腐蚀性工作介质环境中工作的列管式换热器。 The technical problem to be solved by the utility model is to provide a shell and tube heat exchanger with high heat exchange efficiency and capable of working in a corrosive working medium environment.
为解决上述技术问题，本实用新型一种列管式换热器，包括壳体，该壳体内设有换热管束，换热管束的两端装有管板，所述壳体的两端分别设有封头，封头与管板相连，所述换热管束的管程部分设有折流档板，所述壳体两端的封头分别设有介质I进口和介质I出口，壳体的上部和下部分别设有介质II进口和介质II出口，所述换热管束由聚四氟乙烯或聚全氟乙丙烯制成的大径换热管和小径换热管组成，大径换热管和小径换热管在所述壳体内交错设置。 In order to solve the above-mentioned technical problems, the utility model provides a tube-and-tube heat exchanger, which includes a shell, and a heat exchange tube bundle is arranged in the shell, and tube plates are installed at both ends of the heat exchange tube bundle, and the two ends of the shell are respectively A head is provided, and the head is connected with the tube sheet. The tube side of the heat exchange tube bundle is provided with a baffle plate. The heads at both ends of the shell are respectively provided with a medium I inlet and a medium I outlet. The upper part and the lower part are respectively provided with a medium II inlet and a medium II outlet. The heat exchange tube bundle is composed of a large-diameter heat exchange tube and a small-diameter heat exchange tube made of polytetrafluoroethylene or polyfluoroethylene propylene. The large-diameter heat exchange tube and small-diameter heat exchange tubes are arranged alternately in the housing.
采用上述结构的列管式换热器，由于所述换热管束由聚四氟乙烯或聚全氟乙丙烯制成的大径换热管和小径换热管组成，大径换热管和小径换热管在所述壳体内交错设置，因此换热管能够在具有腐蚀性工作介质环境中工作，由于换热管中具有管径较小的小径换热管，因此当工作介质流量小时也能够保证管内工作介质充满状态，换热效率高。 In the tube-and-tube heat exchanger with the above structure, since the heat exchange tube bundle is composed of large-diameter heat exchange tubes and small-diameter heat exchange tubes made of polytetrafluoroethylene or polyperfluoroethylene propylene, the large-diameter heat exchange tubes and small-diameter The heat exchange tubes are arranged staggeredly in the shell, so the heat exchange tubes can work in the environment of corrosive working medium. Since the heat exchange tubes have small-diameter heat exchange tubes with small diameters, the heat exchange tubes can also work when the flow rate of the working medium is small. Ensure that the working medium in the tube is full, and the heat exchange efficiency is high.
