Steam generator

Abstract

The invention discloses a steam generator. The steam generator comprises a pipe provided with a liquid inlet and a steam outlet. The pipe is formed in the mode that heating pipes are connected in series or in parallel, and the outer surfaces of all the heating pipes are partly or fully covered with continuous heating elements with power independently controlled on or off. According to the steam generator, liquid is heated to steam through the heating pipes, heating efficiency and speed are high, and when the liquid flows through the heating pipes, the liquid can be rapidly converted into the steam, residual does not exist, the steam can be obtained after 3 s to 10 s during normal working, and the requirement of rapidly obtaining the steam can be met; all the heating pipes can independently control heating, the corresponding-number heating pipes can be started to work according to the using requirement amount of the steam, work is flexible, and the using requirements on different occasions can be met.

Description

technical field [0001] The invention relates to a heating device, in particular to a steam generator. Background technique [0002] There are two main methods of steam generation commonly used at present. The first is to put the liquid in the tank, close the tank with a cover up and down, heat the tank to keep the tank at a high temperature, and when a small amount of liquid is injected into the tank, the liquid is vaporized and transformed into Steam, the overall heat conversion rate of this method is low, the preheating time is long, and it is easy to leak. After the steam operation is completed, the temperature of the entire system is very high, and the preheating inertia is large. The second is the boiler type, which uses a boiler to replace the tank to heat the liquid to convert the liquid into steam. This method can solve the problem of air leakage, but there are defects in efficiency and quality, and the temperature rises slowly at the beginning. Scale affects subse...

Problems solved by technology

The first is to put the liquid in the tank, close the tank with a cover up and down, heat the tank to keep the tank at a high temperature, and when a small amount of liquid is injected into the tank, the liquid is vaporized and transformed into Steam, the overall heat conversion rate of this method is low, the preheating time is long, and it is easy to leak. After the steam operation is completed, the temperature of the entire system is very high, and the preheating inertia is large.

The second is the boiler type, which uses a boiler to replace the tank to heat the liquid to convert the liquid into steam. This method can solve the problem of air leakage, but there are defects in efficiency and quality, and the temperature rises slowly at the beginning. Scale affects subsequent normal use, and the heat loss in the entire boiler is large when not in use

The above two methods take about one minute from the beginning of heating to the steam coming out, which is difficult to meet the requirements of quickly obtaining steam
