Embodiment Construction

[0015] see figure 1 and figure 2 , figure 1 It is a schematic diagram of the front structure of the 48-pair rod polysilicon reduction furnace of the present invention. figure 2 It is a top view of the chassis of the present invention. Depend on figure 1 of figure 2 It can be seen that the 48 pairs of rod polysilicon reduction furnaces of the present invention include a furnace body 1 and a chassis 2. The furnace body 1 has a cooling water chamber, and the chassis 2 has a water-cooled structure. On the chassis 2, 48 pairs are evenly arranged in four circles. (96) electrodes 4, 18 pairs of electrodes 4 are arranged on the outermost circle of the chassis 2, 14 pairs of electrodes 4 are arranged on the second circle, 10 pairs of electrodes 4 are arranged on the third circle, and 6 pairs of electrodes 4 are arranged on the innermost circle. The positive and negative poles of the electrodes 4 are arranged on the chassis 2 at intervals one by one.

Abstract

The invention relates to a polycrystalline silicon reduction furnace with 48 pairs of rods, especially to a reduction furnace for manufacturing polysilicon by electrochemical reaction. The polycrystalline silicon reduction furnace provided by the invention comprises a furnace body (1) and a chassis (2) and is characterized in that the furnace body (1) is equipped with a cooling water jacket; the chassis (2) is provided with a water-cooled structure; and 48 pairs of electrodes, namely 96 electrodes, are uniformly arranged on four circles of the chassis (2), wherein the outermost circle of the chassis (2) is provided with 18 pairs of electrodes (4); the second circle is equipped with 14 pairs of electrodes (4); the third circle is provided with 10 pairs of electrodes (4); the innermost circle is provided with 6 pairs of electrodes (4); and anode and cathode of the electrodes (4) are arranged one by one at intervals on the chassis (2). The polycrystalline silicon reduction furnace provided by the invention has a reasonable internal structure layout. The output of a single polycrystalline silicon reduction furnace is raised in comparison with that of a present reduction furnace. The invention can be used to greatly reduce the relative production power consumption of polysilicon per kilogram and relatively decrease the comprehensive energy consumption and production cost of polysilicon.

Description

technical field [0001] The invention relates to a reduction furnace for producing polysilicon, in particular to a reduction furnace for producing polysilicon by electrochemical reaction. It belongs to the technical field of polysilicon preparation. Background technique [0002] Polycrystalline silicon is the direct material for the production of monocrystalline silicon, and high-purity polycrystalline silicon is the basic material for semiconductor devices such as photoelectric conversion cells and integrated circuits.
