Embodiment 1

[0040] Such as figure 1 As shown, a high-voltage electrode boiler includes a vertical casing 1 filled with a certain amount of non-condensable gas. As a specific implementation, the non-condensable gas described in this embodiment is nitrogen. A partition 3 is arranged inside the housing 1, and the partition 3 divides the inner space of the housing 1 into an upper space and a lower space.

[0041] The first heat exchanger 51 and the electrode 2 are sequentially arranged in the upper space from top to bottom, and the first heat exchanger 51 and the electrode 2 are respectively fixedly connected to the casing 1 . Both the water inlet and the water outlet of the first heat exchanger 51 are located outside the casing 1 .

[0042] As a specific implementation, such as figure 1 As shown, in this embodiment, the casing of the first heat exchanger and the casing of the boiler are fixedly connected to form a unified cavity, and the heat exchange tubes of the heat exchanger extend in...

Embodiment 2

[0055] A zero electrode cylinder is arranged outside the electrodes in the upper space, and the electrodes are arranged symmetrically with respect to the center of the zero electrode cylinder in the horizontal plane, and the rest of the structure is the same as that of the first embodiment.

Embodiment 3

[0057] Such as image 3 As shown, a high-voltage electrode boiler includes a horizontal casing 1 filled with a certain amount of non-condensable gas. As a specific implementation, the non-condensable gas described in this embodiment contains nitrogen. A partition 3 is arranged inside the housing 1, and the partition 3 divides the inner space of the housing 1 into an upper space and a lower space.

[0058] The left end of the upper space is provided with a zero-electrode cylinder 7 with a circular cross-section, and an electrode 2 is disposed in the zero-electrode cylinder 7 . The zero electrode cylinder 7 and the electrode 2 are fixedly connected to the housing 1 respectively. The three electrodes 2 are arranged at the same height and are arranged symmetrically with respect to the center of the zero electrode cylinder 7 in the horizontal plane. That is, the projections of the electrodes 2 in the horizontal plane are sequentially connected to form an equilateral triangle, an...

Abstract

The invention discloses two high-voltage electrode boilers including a horizontal high-voltage electrode boiler and a vertical high-voltage electrode boiler, and relates to the technical field of boiler equipment. According to one high-voltage electrode boiler, a certain amount of non-condensable gas is injected into a shell, and a partition plate is arranged and divides the inner space of the shell into an upper space and a lower space. Electrodes are located in the upper space, and the lower space contains liquid with certain conductivity and also is a non-condensable gas storage space during normal running. The non-condensable gas is stored in the lower space during normal running, the content in the upper space is low, and the heat exchange capability of a first heat exchanger is guaranteed. An air exchange channel for communicating with the upper space and the lower space, a liquid supply pipeline and a liquid return pipeline are arranged between the upper space and the lower space. According to the high-voltage electrode boiler, the breakdown voltage is improved through filling of the non-condensable gas, arc discharge is avoided, multi-time cyclic usage can be achieved afterthe high-voltage electrode boiler is filled with the non-condensable gas at a time, and frequent inflation and deflation are not needed.

Description

technical field [0001] The invention relates to the technical field of boiler equipment, in particular to a high-voltage electrode boiler. Background technique [0002] In recent years, due to the impact of the economic downturn, the growth rate of electricity demand has slowed down. Especially in Northeast China and Xinjiang and other places, it is difficult to adjust the peak of the power grid during the winter heating period. The phenomenon of abandoning wind and solar is serious, and the contradiction between power supply and demand is prominent. The traditional coal heating method emits serious pollutants, causing smog to lock the city in winter. All over the country, small and medium-sized coal-fired boilers are gradually phased out, and coal-to-electricity clean energy is adopted. [0003] The high-voltage electrode boiler is a high-efficiency and zero-pollution energy supply equipment. The 6-35kv high-voltage electricity is directly inserted into water with a certai...
