According to different heating sources, boilers are divided into many forms. In recent years, electrode steam boilers have been used more and more widely. The electrode steam boiler heating technology adopts the method of passing current through the water between the electrodes and directly heating the water to generate steam. It has high thermal efficiency, fast electric heating speed, and is environmentally friendly and pollution-free.
因在运行的过程中，电极直接加热给水产生蒸汽，所以对给水水质要求很高，必须严格控制电导率，电导率过低产汽量减少，电导率过高容易击穿。为获得具有合适电导率的水质，电极蒸汽锅炉需要加药设备的配合调整电极锅炉内部水的电导率，但是调整电导率的系统过于复杂，需要投入大量的成本与人力，而且运行管理要求较高。除此之外，现有技术中的电极蒸汽锅炉中，三相电极产汽出现不均匀现象，导致中心线电流偏大。During operation, the electrode directly heats the feed water to generate steam, so the quality of the feed water is very high, and the conductivity must be strictly controlled. If the conductivity is too low, the steam production will be reduced, and if the conductivity is too high, it will easily break down. In order to obtain water quality with a suitable conductivity, the electrode steam boiler needs the cooperation of chemical dosing equipment to adjust the conductivity of the water inside the electrode boiler, but the system for adjusting the conductivity is too complicated, requiring a lot of cost and manpower, and has high requirements for operation and management . In addition, in the electrode steam boiler in the prior art, the steam production of the three-phase electrodes is not uniform, resulting in a large center line current.

Each phase electrode 31 is correspondingly immersed in an inner cylinder 4 . The section of each inner cylinder 4 is composed of five straight lines and one arc. The arc surface where the arc is located is the wall of the electrode cylinder. The sides of all the inner cylinders 4 closest to the center of the furnace cylinder 1 form an equilateral polygon. There are three groups of inner cylinders 4 and phase electrodes 31, three groups of inner cylinders 4 and three groups of phase electrodes 31 are evenly distributed around the central axis of the electrode cylinder 11, and the gap between adjacent inner cylinders 4 and adjacent phase electrodes 31 The angles are all 120 degrees.
目前，我国生产、配送的都是三相交流电，本实施例的三组相电极31与三条相线一对一连接，形成同一平面上均匀布置的三相电极。中心线(俗称零线)与锅炉本体连接，形成用电负载通路。锅炉本体的外侧还设有接线柱24，相电极31通过接线柱24与外部电源接通。相电极31与接线柱24一一对应，形成三相电极。本实施例由于三相电极水位均匀，相电极31产汽均匀，相与相之间电流几乎相同，中心线电流极小，避免三相电场不平衡产生安全隐患，使用更安全。At present, my country produces and distributes three-phase alternating current. The three sets of phase electrodes 31 in this embodiment are connected one-to-one with the three phase lines to form three-phase electrodes evenly arranged on the same plane. The center line (commonly known as the zero line) is connected to the boiler body to form an electrical load path. The outside of the boiler body is also provided with a terminal 24 through which the phase electrode 31 is connected to an external power supply. The phase electrodes 31 are in one-to-one correspondence with the terminal posts 24 to form three-phase electrodes. In this embodiment, because the water level of the three-phase electrodes is uniform, the steam production of the phase electrodes 31 is uniform, the current between phases is almost the same, and the current of the center line is extremely small, which avoids potential safety hazards caused by unbalanced three-phase electric fields and is safer to use.
以上对本发明的实施例进行了详细说明，对本领域的普通技术人员而言，依据本发明提供的思想，在具体实施方式上会有改变之处，而这些改变也应视为本发明的保护范围。The embodiments of the present invention have been described in detail above. For those of ordinary skill in the art, according to the ideas provided by the present invention, there will be changes in the specific implementation, and these changes should also be regarded as the scope of protection of the present invention. .
