Electrode type water heating equipment

Abstract

The invention provides electrode type water heating equipment. A middle partition plate in a tank body divides the tank body into an upper cavity and a lower cavity, and the upper cavity is connectedwith a vacuum pump; three insulating sleeves are fixedly mounted on the middle partition plate; a zero electrode comprises a circular steel plate and three sunken steel pipe sleeves which are uniformly distributed in the circumferential direction and are fixed with the circular steel plate; the three steel pipe sleeves are correspondingly mounted in the three insulating sleeves in an up-down sliding manner; a certain gap is reserved between a phase electrode and the steel pipe sleeves; a hydraulic cylinder for driving the zero electrode to lift is fixedly mounted in the center of the middle partition plate, and the upper end of a piston rod of the hydraulic cylinder is fixed in the center of the circular steel plate through an insulating pad; oil inlet and outlet pipes of the hydraulic cylinder penetrate out of the side walls of the upper and lower cavities and then are connected with a hydraulic pump to ensure that no moving part penetrates through the tank body. The equipment is lowin overall manufacturing cost, small in size and good in load adjustment stability and safety performance, the load adjustment rate is guaranteed, the use amount of inorganic salt serving as electrolyte is reduced, and pollution is reduced.

Description

technical field [0001] The invention relates to a high-voltage electrode-type water heating device, and the applicable voltage includes but not limited to 6KV, 10KV, 20KV and 35KV. Background technique [0002] One of the technical routes adopted by the existing electrode type water heating equipment is the full immersion type, that is, the heating electrodes are all immersed in the conductive medium water, and the phase electrode and the zero electrode conduct electricity through the medium water in the middle, thereby heating the medium water. A protective shield is set between the zero electrodes, and the conductive area of ​​the medium water is changed by the lifting of the protective shield, thereby changing the heating power and controlling the temperature of the hot water outlet. The protective shield works in a high-temperature environment of about 100°C, and at the same time it must withstand a high voltage of 10KV, which requires high material requirements. At pres...

AI Technical Summary

Problems solved by technology

The semi-submerged type uses a water pump to pump the medium water into the inner tank. The water level is prone to fluctuations. The submerged parts of the three electrodes are inconsistent, resulting in unbalanced three-phase loads. In severe cases, it may cause the protection trip of the high-voltage switchgear; at the same time, the fluctuation of the water level will also cause load fluctuations. , affecting the quality of the power grid; the water level adjustment has hysteresis, which affects the power adjustment rate; the fluctuating water splash may also form arc discharge, which affects safety performance
