Problems solved by technology

After the liquid enters one cover from the liquid inlet, it quickly flows out from the liquid outlet on the other cover through the heat exchange tube. The flow of the liquid is only as long as the heat exchange tube, and the process is shorter. The efficiency of the liquid has not been fully utilized, and the heating efficiency of the liquid is low

Abstract

The invention relates to a heater, in particular to a heater which uses steam to heat liquid flowing through heat exchange tubes. The heater comprises a shell, wherein the shell is cylindrical and is arranged horizontally. The wall of the shell is provided with a steam inlet; two ends of the shell are provided with tube plates; the tube plates are provided with a plurality of tube holes; a plurality of heat exchange tubes are arranged between the two tube plates; and two ends of the heat exchange tubes extend into corresponding tube holes of corresponding tube plates in a sealed mode respectively. The front end and the back end of the shell are provided with a front sealing cover and a back sealing cover respectively. The heater is characterized in that: two transverse clapboards are arranged in the front sealing cover, and the two transverse clapboards divide the inner cavity of the front sealing cover into an upper cavity, a middle cavity and a lower cavity. One transverse clapboard is arranged in the back sealing cover and divides the inner cavity of the back sealing cover into an upper cavity and a lower cavity; and the front sealing cover is provided with a liquid inlet and a liquid outlet, wherein the liquid inlet is communicated with the upper cavity in the front sealing cover, and the liquid outlet is communicated with the lower cavity in the front sealing cover. By using the heater to heat the liquid, the heating efficiency is high. The heater is suitable for a seawater desalination system.

Description

technical field [0001] The invention relates to a heat exchange device. Specifically, it is a heater that uses steam to heat the liquid flowing through the heat exchange tube. Suitable for seawater desalination system. Background technique [0002] Currently, heaters that use steam to heat liquid flowing through heat exchange tubes include a shell that is cylindrical and arranged horizontally, with a steam inlet on the wall of the shell. There are tube sheets at both ends of the shell, several tube holes on the tube sheets, and several heat exchange tubes between the two tube sheets. There are covers at both ends of the housing, and the covers are hemispherical. One cover is provided with a liquid inlet, and the other cover is provided with a liquid outlet. When working, while the hot steam is sent into the casing through the steam inlet, the heated liquid passes through the liquid inlet and one cover, flows through the heat exchange tube and then flows out from the liqu...
