High-temperature furnace circulating water cooling system

Abstract

The invention discloses a high-temperature furnace circulating water cooling system. The high-temperature furnace circulating water cooling system comprises a high level water tank, a cooling tower, alow level water tank and an emergency drain valve; the high level water tank is higher than the arrangement position of a high-temperature furnace and is connected with the high-temperature furnace through a first pipe; the cooling tower is connected with the high-temperature furnace through a second pipe; a circulating pump is arranged on the second pipe; hot water output from the high-temperature furnace is conveyed to the cooling tower through the second pipe through the circulating pump; the cooling tower is connected with the high level water tank through a third pipe; the arrangement position of the low level water tank is lower than the arrangement positions of the high level water tank and the high-temperature furnace; the low level water tank is connected with the second pipe through a fourth pipe; the connecting part of the fourth pipe and the second pipe is positioned between the high-temperature furnace and the circulating pump; the emergency drain valve is arranged on thefourth pipe; and the emergency drain valve is automatically opened when the circulating pump stops or water circulation stops. According to the high-temperature furnace circulating water cooling system disclosed by the invention, delayed cooling can be performed on the high-temperature furnace when the circulating pump stops or the water circulation stops, so that the safety of the high-temperature furnace in a fault state is ensured.

Description

technical field [0001] The invention relates to the technical field of high-temperature furnace water cooling, in particular to a high-temperature furnace circulating water cooling system. Background technique [0002] The temperature in the reduction furnace, ingot furnace and single crystal furnace in polysilicon enterprises is as high as 1000 degrees. The heat cannot be taken away in time. In this case, even if the furnace is stopped immediately, the heat in the equipment is enough to burn out the high-temperature furnace body or key components, causing huge losses. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a circulating water cooling system for a high-temperature furnace, which can delay cooling of the high-temperature furnace when the circulating pump trips or cuts off, thereby ensuring the safety of the high-tempe...
