Embodiment 1
[0020] The high-pressure drainage water recovery system of the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 As shown, the high-pressure drainage water recovery system includes a boiler drainage pipe 1 and a steam engine drainage pipe 2, and the boiler drainage pipe 1 and the steam engine drainage pipe 2 are all communicated with the fixed row expansion container 3, in order to recover the high-pressure drainage water The pipeline of the system is simple and easy to maintain. All the drain pipes of the boiler should be integrated into the boiler drain pipe 1 first, and then the boiler drain pipe 1 is connected to the fixed row expansion container 3. In this embodiment, the high-pressure drain water is recovered. The system also includes a hydrophobic expansion tank 4, the hydrophobic expansion tank 4 is communicated with the drain tank 5, the hydrophobic expansion tank 4 is communicated with the boiler drain p...
Embodiment 2
[0025] The difference between this embodiment and Embodiment 1 is that: figure 2 As shown, the boiler drain pipe 1 control valve is a two-position reversing valve 10 arranged between the boiler drain pipe 1, the fixed row expansion vessel 3, and the drain expansion tank 4. By setting the boiler drain pipe 1 control valve as Two-position reversing valve 10, the high-pressure drainage water recovery system is easy to operate when switching the drainage line; One-position reversing valve 10, by setting the steam engine drain pipe 2 control valve as two-position reversing valve 10, the high-pressure draining water recovery system is easy to operate when switching the drainage line; The water flow path is the same, the difference is that the one-way valve in Embodiment 1 is replaced by the two-position reversing valve 10 in this embodiment. By setting the two-position reversing valve 10 in this embodiment, the high-pressure drainage water recovery system is laid The operation of ...
Embodiment 3
[0027] The difference between this embodiment and Embodiment 2 is that: image 3As shown, the two-position reversing valve 10 is an electromagnetic reversing valve, and by setting the two-position reversing valve 10 as an electromagnetic reversing valve, it is more convenient to operate when the high-pressure drainage water recovery system switches lines; and in this embodiment, the boiler A detector 13 for detecting water flow parameters in the pipeline is added on the drainage pipe 1 and the steam engine drainage pipe 2, and the detector 13 is a detection device for detecting the ratio of the liquid phase and the vapor phase in the pipeline. The electromagnetic reversing valves are connected, that is, the detector 13 can control the action of the electromagnetic valve. By setting the detector 13 and making the detector 13 control the action of the electromagnetic valve, the high-pressure drainage water recovery system is automated and more convenient to use.
