Problems solved by technology

[0004] In the operation of the polysilicon reduction furnace, its supporting transformer is generally equipped with a cooling system for cooling it. The existing cooling system does not have a good cooling effect on the transformer. In more serious cases, it will be shut down due to the burnout of the transformer. The production efficiency of polysilicon has a great influence

Embodiment 1

[0039] Such as figure 1As shown, in this embodiment, a cooling system for a transformer used in a reduction furnace is specifically provided to solve the problem of cooling the transformer 2 in the production of an existing polysilicon reduction furnace, which mainly includes a cooling box 1 that can be opened and closed on one side, For the design of the cooling box 1, the cooling box 1 is set as a rectangular box with one side opening, and the front side of the cooling box 1 is the opening side and this side is provided with an openable and closable airtight door. There are three transformers 2, and under the operation of each transformer 2, the power supply for the normal operation of the reduction furnace is realized. In actual application, the airtight door is not a whole, it includes a door frame and a plurality of door panels inside the door frame, each of the door panels is hingedly connected to the door frame and a locking member is provided between each door panel an...

Embodiment 2

[0046] On the basis of the cooling system provided in Embodiment 1, in this embodiment, a cooling method for a transformer used in a polysilicon reduction furnace is specifically provided, and the cooling method includes:

[0047] S1: Real-time monitoring of the temperature in the cooling box 1. In practical application, temperature monitors can be arranged at multiple points in the cooling box 1, and the maximum value of each temperature monitor can be taken as the temperature reference value of the cooling box 1.

[0048] S2: Adjust the opening degree of one side of the cooling box 1 by monitoring the outdoor temperature in real time. The adjustment logic is: divide the opening degree of one side of the cooling box 1 from small to large into four levels. The fourth level here refers to the opening degree in embodiment 1 The airtight door includes four door panels, opening one door panel is the first level of opening, opening two door panels is the second level of opening, and...

Embodiment 3

[0053] On the basis of the cooling system of the transformer used in the reduction furnace provided in Embodiment 1, in order to further optimize its maintainability during operation, as Figure 5 As shown, it is improved as follows:

[0054] A plurality of groups of slide rails 10 are arranged below the support frame, and each group of slide rails 10 is equipped with a suspension 8 slidably mounted on it respectively, and each suspension 8 is equipped with the cooling fan 7 respectively, and by pushing the suspension 8. The cooling fan 7 can be installed in a preset position. When the cooling fan 7 needs maintenance, the suspension 8 can be pulled to pull the cooling fan 7 out and cooperate with the staff for maintenance.

[0055] Each suspension 8 is provided with a limit block 11, and the limit block 11 is provided with a limit hole; a plurality of telescopic electromagnets 9 are arranged below the support frame, and the telescopic rod of the telescopic electromagnet 9 and ...

Abstract

The invention discloses a cooling system of a transformer for a reduction furnace and a cooling method thereof, and belongs to the technical field of polycrystalline silicon reduction furnaces. The cooling system comprises a cooling box with one side capable of being opened and closed, and further comprises a plurality of transformers arranged in the cooling box, wherein each transformer is provided with a plurality of cooling pipes on the corresponding side wall of the cooling box, and the cooling pipes are connected in parallel and then are connected with an external cooling device; a plurality of cooling fans, wherein each cooling fan is arranged in an area below each transformer; at least two side wall axial flow fans which are arranged above the two sides of the area where the transformers are located respectively, wherein the starting and stopping of the external cooling device, the cooling fans and the side wall axial flow fans are determined according to the temperature in the cooling box, so that the purposes of improving the cooling effect on the transformer and further ensuring the stability and reliability of a polycrystalline silicon production process are achieved.

Description

technical field [0001] The invention belongs to the technical field of polysilicon reduction furnaces, and in particular relates to a cooling system for a transformer used in a reduction furnace and a cooling method thereof. Background technique [0002] Polycrystalline silicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooled conditions, silicon atoms are arranged in the form of diamond lattices to form many crystal nuclei. If these nuclei grow into crystal grains with different crystal plane orientations, these When the crystal grains are combined, they crystallize into polysilicon, which is widely used in solar cells, photovoltaic panels and other industries. [0003] At present, the modified Siemens method of growing polysilicon using a bell-type chemical vapor deposition reactor (polysilicon reduction furnace) is the mainstream method for producing polysilicon. Austenitic stainless steel alloys are usually selected to manufactur...
