Therefore, a clean and green energy source for heat supply is urgently needed. At present, the minimum load of a high-voltage electrode boiler during operation is 6-10%, and the load of 0-100% cannot be adjusted in a stepless manner, so that the energy is greatly wasted; in addition, the existing high-voltage electrode boiler basically adopts a pressure stabilizing device added on the system to realize the pressure stability of the system, and the pressure stability can not be realized through the boiler.

According to the lifting type center cylinder high-voltage electrode boiler device for stepless regulation and pressure stabilization of nitrogen, the nitrogen accounts for 20% -70% of the volume of the boiler.
The invention relates to a lifting type center cylinder high-voltage electrode boiler device for stepless regulation of nitrogen and pressure stabilization, which has the working principle that: the load change of the high-voltage electrode boiler is mainly realized by heating circulating water quantity through the high-voltage electrode, the boiler is 0 load when the high-voltage electrode is not contacted with the circulating water, and the effective load is 100 percent when the high-voltage electrode is completely immersed in the circulating water. The invention realizes the liquid level change of the inner cylinder of the boiler, namely the amount of the high-voltage electrode immersed circulating water, by the lifting central cylinder in the boiler so as to realize the stepless regulation of the load of the boiler of 0-100 percent.
The specific description is as follows: the boiler has stepless regulation function, the central cylinder of the boiler is in a lifting type, and the central cylinder is in a cylinder structure with holes at two ends. When the boiler is in 0 load, the top end of the central cylinder is flush with the bottom of the inner cylinder of the boiler, and the boiler circulating water flows to the bottom of the boiler through the top opening of the central cylinder and is not in contact with the high-voltage electrode, so that the circulating water does not take away any heat, and the load is 0; when the load of the boiler is increased, the servo motor drives the central cylinder to be raised through the driving shaft, the liquid level of the inner cylinder of the boiler is gradually raised at the moment, the part of the high-voltage electrode immersed in circulating water of the boiler is correspondingly increased, the amount of circulating water heated by the boiler is increased, and the load of the boiler is synchronously raised at the moment; when the servo motor drives the central cylinder to rise to the highest position through the driving shaft, the effective high-voltage electrodes are completely immersed in the circulating water of the boiler, the load of the boiler reaches 100%, and the heated circulating water flows into the top of the boiler through the top of the central cylinder and then supplies heat. When the load is reduced, the servo electrode reverses to enable the central cylinder to descend, the contact part of the boiler circulating water and the high-voltage electrode can be synchronously reduced, and at the moment, the stepless regulation of 100% -0 load of the boiler is realized.
The lifting type central cylinder high-pressure electrode boiler device for stepless regulation of nitrogen pressure has a nitrogen pressure stabilizing function, nitrogen is inert gas, chemical generation is not easy to occur, but pressure change caused by temperature change and expansion with heat and contraction with cold can be absorbed, so that a certain amount of nitrogen with pressure is injected into the boiler, and the pressure stability in the boiler can be realized. According to the invention, the top of the high-voltage electrode boiler is connected with a nitrogen source through a nitrogen pipeline, and pressurized nitrogen accounting for 20-70% of the volume of the boiler is injected into the boiler from the nitrogen source, so that the pressure inside the boiler is stable.
The lifting type center cylinder high-voltage electrode boiler device for stepless regulation of nitrogen pressure can realize stepless regulation of 0-100% of load, can realize pressure stabilization only by the boiler, does not increase the configuration of a boiler circulating water system, and therefore has the advantages of simple structure, low investment cost, stable operation and energy consumption saving.
In conclusion, the lifting type central cylinder high-voltage electrode boiler device for stepless regulation of nitrogen pressure has the advantages of simple structure, low investment cost, stable operation, stepless regulation, stable pressure and energy conservation.
