Steam generator core

Abstract

The invention discloses a steam generator core, which comprises a water inlet pipe, a water inlet tank, a lower tank, a steam-water separator and a plurality of heating pipes, wherein the water inlet pipe is communicated with the water inlet tank; the heating pipes are uniformly arranged between an upper tank and the steam-water separator; the lower ends of the heating pipes are communicated withthe lower tank, while the upper ends are extended into the steam-water separator; the lower part of the steam-water separator is communicated with the lower tank through a return pipe; the water inlet tank is an annular water tank and arranged above the lower tank and surrounds the heating pipes; and the lower part of the water inlet tank is communicated with the lower tank. The heating pipes arearranged in an approximately closed space formed by the upper tank, the lower tank and a boiling water tank, and most of heat dissipated to the outside by the heating pipes is absorbed by the steam-water separator, the lower tank and the water inlet tank so as to improve the heat utilization rate of the steam generator core and improve the external environment of the steam generator core.

Description

[technical field] [0001] The invention relates to a steam generator, in particular to a steam generator core. [Background technique] [0002] Steam is the traditional source of heat power. People widely use water vapor in civil and industrial production, its importance is self-evident. The steam generator that is currently used more and most economically is the traditional water-tank electric steam boiler. The disadvantage of the water-tank electric steam boiler is that it is not an instant-on type. It takes 20-40 minutes; only use the temperature control switch to control, and the water will be boiled at the set temperature to keep the heat and pressure. Power consumption is not conducive to energy saving. U-shaped heating element is used, which is easy to rust and scale, which is not hygienic enough. [0003] In order to overcome the shortcomings of the above-mentioned traditional gall-type electric steam boilers, instant steam generators have appeared on the market. ...

AI Technical Summary

Problems solved by technology

The disadvantage of this steam generator is that,

[0004] 1. The heat utilization rate of the heating tube is not high, because the heating tube is exposed, at least 30% of the heat is emitted outward, not only the heat is not fully utilized, but also the operating environment of the steam generator core is deteriorated;

[0005] 2. The quartz heating tube is exposed, and the electrodes are also exposed, which is easy to cause the heating tube to break, burn and electric shock accidents, which is not safe enough;

[0006] 3. The structure is unreasonable, and the production and assembly are difficult, which is not conducive to mass production;

[0007] 4. It is not possible to manufacture cores for pressurized steam generators
