Problems solved by technology

[0002] In water systems in power plants and other industries, the steam heat exchange equipment currently used is a shell-and-tube heater. The steam channel inside the shell-and-tube heater is a straight tube with a small heat transfer area; a large number of straight tubes , resulting in many channels, many internal welding points, and it is difficult to detect leaks; when the amount of heating water is large, its overall size is also large, and part of the steam of this tubular heater is inside the shell, so the outside of the shell must be done insulation measures

Embodiment 1

[0021] Such as figure 1 The shown steam heater assembly includes a stainless steel cylinder 1, and at least one set of heaters 2 are arranged inside the stainless steel cylinder 1, and the heater 2 is helical, and the cylinder 1 is provided with a A brine inlet 3 and a desalinated water outlet 4, the desalinated water inlet 3 is set at the bottom of the cylinder 1, and the desalinated water outlet 4 is set at the top of the cylinder 1. The heater 2 is provided with a steam inlet 5 and a steam outlet 6 , and the steam inlet 5 and the steam outlet 6 are arranged at the same end of the heater 2 . The top of the desalinated water inlet 3 is provided with a water diversion cover 8, and a number of through holes are evenly distributed on the water diversion cover 8 to prevent the generation of water columns when the desalinated water enters the water, which is not easy to distribute. By adding the water diversion cover 8, the water is dispersed Open, evenly distributed upstream.

Abstract

The invention discloses a steam heater assembly comprising a stainless steel cylinder. At least one heater is arranged in the stainless steel cylinder. Each heater is arranged in a spiral pipe manner.The cylinder body is provided with a demineralized water inlet and a demineralized water outlet. Each heater is provided with a steam inlet and a steam outlet. The steam heater assembly is high in heat exchange efficiency and small in boundary dimension, water pressure detection is convenient, and it is ensured that leakage is avoided in use.

Description

technical field [0001] The invention relates to the technical field of steam utilization, in particular to a steam heater assembly. Background technique [0002] In water systems in power plants and other industries, the steam heat exchange equipment currently used is a shell-and-tube heater. The steam channel inside the shell-and-tube heater is a straight tube with a small heat transfer area; a large number of straight tubes , resulting in many channels, many internal welding points, and it is difficult to detect leaks; when the amount of heating water is large, its overall size is also large, and part of the steam of this tubular heater is inside the shell, so the outside of the shell must be done Insulation measures. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a steam heater assembly with high heat exchange efficiency, small size, convenient water pressure detection and no leakage.
