Problems solved by technology
In the polysilicon production process, the water temperature in the high-temperature water circulation system is about 130°C. The water in the high-temperature state causes the equipment and pipelines in the system to operate under high pressure for a long time. At this time, the traditional constant pressure water replenishment device is no longer applicable.
In addition, the traditional constant pressure water supply device also has the disadvantages of complex structure and high cost

The invention relates to the technical field of high-temperature water waste heat recovery, and discloses a constant-pressure water replenishing device which comprises a water tank provided with a water supply valve, a drain valve, a water level monitoring device and a pressure monitoring device. The constant pressure tower is arranged above the water tank and communicated with the water tank, and an exhaust valve and a pressurizing valve connected with a pressurizing device are arranged on the constant pressure tower; the water replenishing valve is arranged on the water tank or the constant pressure tower and is used for replenishing water into the water tank; the programmable control device is connected with each valve on the water tank and the constant-pressure tower and the water replenishing valve, when the water level in the programmable control device is low, the water replenishing valve is opened to replenish water, when the water level in the programmable control device is high, the drain valve is opened to drain water, when the pressure in the programmable control device is low, the pressurizing valve is opened, and when the pressure in the programmable control device is high, the exhaust valve is opened. Therefore, the constant-pressure water replenishing device can stably operate in a preset pressure range and a preset water level range.
Description
technical field [0001] The invention relates to the technical field of high temperature water waste heat recovery, in particular to a constant pressure water replenishing device. Background technique [0002] In the closed water circulation system, expansion water tank, constant pressure tank water replenishment device, etc. are often used to balance the water volume and pressure, avoid frequent opening of safety valve and frequent replenishment of automatic water replenishment valve, etc., and improve the safety and reliability of system operation. In the polysilicon production process, high temperature (120-150°C) and high pressure cooling water is often used to cool the reduction furnace. The waste heat recovery of the generated high-temperature cooling water is used for heat users such as raw material purification processes, which can effectively realize the heat cycle utilization in the process system and reduce the comprehensive energy consumption of process production...
