Discrete electrode type heater

The utility model discloses a discrete electrode type heater. The discrete electrode type heater comprises electrodes and heating rods, wherein the heating rods are connected with the electrodes, the heater is equipped with more than one pair of electrodes, and the electrodes make up a ring; the heating rods are connected with the adjacent electrodes respectively and are uniformly distributed in a furnace body in a circumferential manner; the heating rods are tungsten bars; the bottoms of the heating rods are L-shaped; and each electrode is connected with more than two heating rods. According to the discrete electrode type heater, a pair of electrodes are changed into multiple pairs of electrodes, and multiple pairs of electrodes form the ring, the heating rods are connected with the adjacent electrodes respectively, and the bottoms of the heating rods are made into an L shape, so that the side surface and the bottom of the heater are uniformly distributed, and the bottom structure and the length of the heate
