Abstract

The invention relates to a reactor irradiation hydraulic driving device, which comprises a power generation module and a rotary driving module, wherein the power generation module is installed above a reactor pool; the rotary driving module is installed on an irradiation channel in the reactor pool, and the rotary driving module is an oil-free lubrication hydraulic driving module; and the device further comprises a power delivering module arranged between the power generation module and the hydraulic driving module. The reactor irradiation hydraulic driving device provided by the invention separates rotation operation and hoisting operation of an irradiated element, so that the operation efficiency is improved, the electrical equipment including a centrifugal water pump is installed only above the surface of the reactor pool, the rotation operation is reliable, the electrical equipment is not irradiated and the overhaul is convenient; in addition, the invention obtains water in the reactor pool on the spot and the parts below the surface of the reactor pool is lubricated and cooled by the deionized water in the reactor pool, so that the pool water is not polluted completely.

Description

technical field [0001] The invention belongs to the technical field of irradiation devices in reactors, and in particular relates to a hydraulic drive device for irradiation in reactors. Background technique [0002] It is a common method for the production of single crystal silicon to produce high-purity single crystal silicon by using the irradiation capability of the reactor during operation. The usual method is to set a vertical irradiation tunnel in the irradiation area of ​​the reactor, and place silicon rods (or stacked silicon wafers) in the tunnel to irradiate for a certain period of time. [0003] Due to the large diameter of the silicon rods (Ф75-Ф150), the irradiation channels are usually arranged around the periphery of the core. In order to ensure that the silicon rods with larger diameters are irradiated evenly and the product quality is guaranteed, it is necessary to make the irradiation element itself wind around the vertical line rotate. The original meth...
