Steam generator with vibration autonomously controlled based on pressure

Abstract

The invention provides a steam generator with vibration autonomously controlled based on pressure. The steam generator comprises an electric heating device and a box body, the electric heating deviceis arranged in the box body, the box body comprises a water inlet pipe and a water outlet pipe, the electric heating device comprises a first channel, a second channel and a coiled tube, the coiled tube communicates with the first channel and the second channel, a pressure sensing element is arranged inside the electric heating device to detect the pressure inside the electric heating device, thepressure sensing element is connected with a controller in a data mode, and the controller controls whether an electric heater performs heating according to the detected pressure. The electric heatingdevice can judge whether a stable state is reached according to the internal pressure, and then intelligently control the heating of the electric heater according to the internal pressure, so that internal fluid can be vibrated frequently, and good descaling and heating effects are achieved.

Description

technical field [0001] The invention relates to steam generating equipment, in particular to a steam generator for vibration descaling. Background technique [0002] The steam generator is used to generate steam, which is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into steam. The steam generator has a wide range of applications, and is widely used in clothing factories, dry cleaners, restaurants, steamed bun shops, canteens, restaurants, factories and mines, bean products factories and other places. In the applicant's previous application, a new type of coil-type electric heating coil was developed and researched, such as CN106123306A, so that the elastic tube bundle caused by the expansion of the fluid caused by heating caused heating and descaling Effect. [0003] However, in the application, it is found that the continuous heating of the electric heater will lead to the stability of the fluid in the internal electric heat...

Problems solved by technology

[0003] However, in the application, it is found that the continuous heating of the electric heater will lead to the stability of the fluid in the internal electric heating device, that is, the fluid is not flowing or has little fluidity, or the flow rate is stable, resulting in a greatly weakened vibration performance of the coil, which affects The descaling of the coil and the efficiency of heating, in this regard, Qingdao University of Science and Technology conducted research and developed a new steam generator capable of generating periodic vibrations, and has already applied for patents, the application numbers are 2019101874848, 2019101875431, 2019101866555 , 2019101914489

[0004] However, in practice, it is found that if the vibration of the tube bundle is adjusted through fixed periodic changes, there will be hysteresis and the period will be too long or too short
