Device for monitoring and controlling temperature of outer wall of high-temperature reaction furnace

The invention relates to a high-temperature reaction furnace outer wall temperature monitoring and control device which comprises a cooling water jacket covering the outer wall of a reaction furnace, the cooling water jacket is in a cavity circular ring shape, a water inlet, a water outlet, an overflow port and a steam port are formed in the cooling water jacket, the water inlet is communicated with a cooling water tank through a first pipeline, and the water outlet is communicated with a steam outlet through a second pipeline. The water outlet is communicated with a sewage pipeline through a second pipeline, the overflow port is communicated with a cooling water tank through a third pipeline, and the steam port is communicated with a steam pipe network through a fourth pipeline; and the first pipeline is connected in series with a cooling water booster pump. Through the cooling device, indirect heat exchange between the outer wall of the reaction furnace and cooling water can be achieved, 0.5 MPa steam blowi
