Detailed description of the invention
With reference to the accompanying drawings, in conjunction with the embodiments, the exhaust steam recycle device that the utility model is provided, is described in detail.
Embodiment
With reference to Fig. 1, the exhaust steam recycle device of the present embodiment, it comprises oxygen-eliminating device 1, motor-driven valve 5, three grades of absorption plants 6 of exhaust steam, gas-liquid separation device 7, booster 8, temperature sensor 10, described oxygen-eliminating device 1 is provided with the exhaust steam being connected with oxygen-eliminating device 1 and reclaims house steward 2, water inlet manifold 3, described water inlet manifold 3 ends are provided with supplementing water entrance 4, exhaust steam is reclaimed house steward's 2 ends and is connected with three grades of absorption plants 6 of exhaust steam, three grades of absorption plant 6 one end of described exhaust steam are connected with the supplementing water entrance 4 of water inlet manifold 3 ends by pipeline, the other end is connected with gas-liquid separation device 7 by pipeline, the pipeline that three grades of absorption plants 6 of described exhaust steam are connected with supplementing water entrance 4 is provided with motor-driven valve 5, the pipeline being connected with gas-liquid separation device 7 is provided with temperature sensor 10, described gas-liquid separation device 7 ends are connected with the water inlet manifold 3 of oxygen-eliminating device 1 by booster 8.
It also comprises switch board 11, and described switch board 11 one end are connected with booster 8, and the other end is connected with motor-driven valve 5, temperature sensor 10 respectively.
It also comprises Liquid Level Regulation System 9, and described Liquid Level Regulation System 9 is arranged on the water inlet manifold 3 of oxygen-eliminating device 1, coordinates with supplementing water entrance 4.
The outer row's exhaust steam of oxygen-eliminating device 1 is connected to exhaust steam and reclaims house steward 2, and demineralized water is accessed by supplementing water entrance 4 as working water, sprays into three grades of absorption plants 6 of exhaust steam through motor-driven valve 5.Spraying into of cold water makes three grades of micro-negative pressure of the interior generation of absorption plant 6 of exhaust steam, and exhaust steam is reclaimed to the exhaust steam suction in house steward 2, and exhaust steam is with supplementing water through three grades of instantaneous mixing of absorption plant 6 of exhaust steam, and supplementing water is heated.Water after heating enters gas-liquid separation device 7, and separated on-condensible gas is discharged automatically through discharger; Hot water in gas-liquid separation device 7 is recycled to the water inlet manifold 3 of oxygen-eliminating device 1 through booster 8.The heat energy of steam discharge and condensed water are all reclaimed, and oxygen-eliminating device 1 energy consumption and supplementing water consumption reduce.
