Steam generator

Abstract

The invention relates to the technical field of evaporating equipment, in particular to a steam generator. The steam generator comprises a hollow electromagnetic heating cylinder body and a heat preservation and insulation layer arranged on the outer wall of the electromagnetic heating cylinder body; an electromagnetic heating induction coil is wound on the heat preservation and insulation layer; the inner wall of the electromagnetic heating cylinder body is provided with steam heat pipes; a one-stage water storage container is arranged in the heating cylinder body; a water inlet is formed in the bottom part of the one-stage water storage container; a one-stage preheating water outlet is formed in the upper part of the one-stage water storage container; a two-stage water storage container is arranged between the heating cylinder body and the one-stage water storage container; the one-stage water storage container is sheathed in the two-stage water storage container; a second preheating water outlet is formed in the lower part of the two-stage water storage container; a water level probe is arranged in the two-stage water storage container. Compared with the prior art, the steam generator disclosed by the invention has the advantages that the heating rate is high, the efficiency is high, and energy is saved for 60-70 percent due to the fact that electromagnetic energy is used for heating; generated steam temperature, quantity of steam and water content can be conveniently regulated; the environment is protected; the cost is reduced; the steam generator is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of evaporation equipment, in particular to a steam generator. Background technique [0002] Steam generators are widely used in various occasions that require the use of steam. The food industry usually uses steam generators to generate steam to heat food, such as steaming steamed buns, steaming various delicious dishes, and steaming rice noodles; the clothing industry usually uses steam generators to supply steam to a large number of ironing machines on the production line. [0003] Existing steam generators initially use coal or fuel oil as a heat source, which not only has low combustion efficiency, wastes energy, but also pollutes the environment; then people use electric heating, which has a fast heating speed, but the speed of water supply is not as fast as that of steam The output speed cannot be agreed, either the water supply speed is too fast, resulting in too fast increase of water volume, which ...

[0003] Existing steam generators initially use coal or fuel oil as a heat source, which not only has low combustion efficiency, wastes energy, but also pollutes the environment; then people use electric heating, which has a fast heating speed, but the speed of water supply is not as fast as that of steam The output speed cannot be agreed, either the water supply speed is too fast, resulting in too fast increase of water volume, which prolongs the heating time, or the steam output speed is too fast, which easily leads to water shortage in the box, the danger of dry burning, and the steam cannot be maintained. The temperature is in a constant temperature state, which is not easy to control
