AI Technical Summary

Technical Problem

The heat exchange device of the existing low-temperature liquid water bath gasifier uses a single round tube with smooth outer surface, resulting in a small heat exchange area per unit length and low heat exchange efficiency, which increases equipment materials and manufacturing costs.

Method used

A new heat exchange device including a fixed bracket, a fin tube and a winding tube is adopted. The fin tube and a winding tube are arranged from bottom to top and fixedly installed by a fixed bracket to improve the heat exchange efficiency through the connection between the two.

Benefits of technology

Through the two stages of low-temperature liquid gasification and heating, the finned tube and the winding tube are respectively produced, which improves the heat exchange efficiency and reduces the equipment materials and manufacturing costs.

Abstract

The utility model discloses a novel heat exchange device of a low-temperature liquid water bath type vaporizer, and belongs to the technical field of low-temperature liquid water bath type vaporizers. The heat exchanger comprises a fixing support, finned tubes and winding tubes, the finned tubes and the winding tubes are arranged from bottom to top and fixedly installed through the fixing support, lower ports of the finned tubes are connected with a liquid inlet pipeline, upper ports of the finned tubes are connected with the winding tubes, outlets of the winding tubes are connected with an air outlet pipeline, and the air outlet pipeline is connected with a heat exchanger. The finned tube comprises a plurality of transverse tubes which are sequentially arranged from bottom to top in the transverse direction, and the transverse tubes are connected through winding tube connecting tubes. According to the utility model, the finned tube and the winding tube are respectively utilized through two stages of low-temperature liquid gasification and heating, so that the heat exchange efficiency is improved, and the equipment material and the manufacturing cost are greatly reduced. The problems that a single round pipe with a smooth outer surface is adopted as a heat exchange pipe of a water bath type vaporizer heat exchange device on the market, the heat exchange area of a unit length of the common round pipe is small, and the heat exchange efficiency is low are solved.
