Problems solved by technology

[0004] However, the main circulation system and the pressure stabilization system of the existing constant pressure water replenishment device are isolated by manual valves, or even connected directly by pipelines. Cans can be severely damaged
In some improved systems, a solenoid valve is set between the main circulation system and the airtight diaphragm tank at atmospheric pressure as an isolation valve. Large, it is easy to cause pressure fluctuations in the main system and affect the effect of voltage stabilization. In severe cases, it may cause the main equipment to trip and affect the safety of operation; in addition, the instantaneous pressure relief flow is too large, which is likely to cause damage to valves, downstream pipelines and seals, threatening equipment safety; Due to the small capacity of the stabilized pump, they all run at power frequency. The system pressure is adjusted by controlling the start and stop time of the pump. The pressure fluctuates greatly, and the adjustment is not flexible and accurate enough.

Abstract

The invention discloses a modularized and self-adaptive regulation and voltage stabilization method for a high-voltage power boiler. The method comprises the three conditions that 1, when the pressurevalue of a main circulation system is within a set pressure range; S2, when the pressure of the main circulation system exceeds an upper limit set pressure value; and S3, when the pressure of the main circulation system is lower than the set lower limit. The adjustment voltage stabilization method is designed based on a regulation and voltage stabilization system, the main circulation system andthe voltage stabilization system adopt an electric isolation valve, and when the main circulation system carries out severe overpressure or the water level of a diaphragm tank exceeds an upper limit,the voltage stabilization system is quickly cut off, so that the safety of an electromagnetic isolation valve, the diaphragm tank and the like is ensured; and an electromagnetic proportional regulating valve and a variable-frequency voltage stabilizing pump can be flexibly and accurately adjusted according to the system pressure, the pressure and the flow regulation in the pressure relief and pressure supplement process are flexible, rapid, stable and controllable, and the stability and safety of the main circulation system are improved.

Description

technical field [0001] The invention relates to an adjusting and stabilizing system, in particular to a modularized and self-adapting adjusting and stabilizing method for a high-voltage electric boiler. Background technique [0002] High-voltage electric boilers are widely used in the fields of thermal power flexible peak regulation and electric energy replacement. Thanks to their excellent technical performance such as high voltage, large capacity, low unit cost, and high electrothermal conversion efficiency, they play an important role in related fields as energy conversion devices. important role. The working principle of the high-voltage electric boiler is to use a conductor to pass high-voltage electricity (6~25KV) to the desalted water with electrolyte, so that the water body will heat up and do work, and the closed-loop heat exchange system will be used to output heat energy to the outside. Because of its high electrothermal conversion efficiency (above 99%), large c...
