Technical Field
[0001] This utility model relates to the field of generator set drainage technology, and in particular to a generator set drainage recovery system. Background Technology
[0002] The unit's condensate drainage and recovery system, as an indispensable component of the overall thermal system, is mainly used to drain and collect condensate from various steam and water pipelines throughout the plant, as well as to recover overflow from boiler drums and various containers, and qualified water discharged during equipment maintenance. This system is of great significance for ensuring the safe operation of the unit and improving its economic efficiency.
[0003] When existing steam turbine units are started up, warmed up, or when steam is stagnant for a long time, a large amount of condensate formed by cooling will adhere to the metal wall of the steam exhaust pipe. If the water enters the steam turbine, it will damage the blades and cause serious accidents such as unit vibration, thrust bearing burnout, shaft bending, and cylinder deformation.
[0004] Therefore, it is necessary to provide a new unit effluent recovery system to solve the above-mentioned technical problems. Utility Model Content

[0018] This utility model provides a unit effluent recovery system;
[0019] 1. This utility model can block water vapor through the set blocking structure. When the unit discharges water vapor through the steam discharge pipe, the blocking plate can be manually inserted into the blocking body through the slot and supported by the limiting plate. When the water vapor rises to the inner side of the blocking body, the water vapor is blocked by the mesh-like blocking plate. The moisture in the water vapor is adsorbed onto the inner wall of the steam discharge pipe and the blocking plate to form condensate, thereby blocking the water vapor and facilitating the subsequent recovery of condensate.
[0020] 2. This utility model can collect condensate through a set collection structure. After the condensate is adsorbed onto the inner wall of the steam discharge pipe and the baffle plate, the condensate dripping along the inner wall can be collected by the ring-shaped collection tray. It can then be flowed to the filter body through the connecting pipe. The condensate is further filtered by the filter plate inside the filter body and discharged through the drain pipe, thereby realizing the recycling of condensate. Attached Figure Description

[0029] The blocking structure includes a blocking body 2, a slot 3 and a blocking plate 5. The blocking body 2 is fitted onto the steam discharge pipe 1. A slot 3 is opened on one side of the blocking body 2. Two sets of slots 3 are opened. The blocking plate 5 is slidably connected inside the two sets of slots 3.
[0030] The steam discharge pipe 1 is equipped with a collection structure, which includes a collection tray 8, a connecting pipe 9, and a filter body 10. The collection tray 8 is fixedly connected to the inner wall of the steam discharge pipe 1, and the filter body 10 is fixedly connected to one side of the steam discharge pipe 1. One side of the collection tray 8 is connected to the filter body 10 through the connecting pipe 9.
[0031] It should be noted that when the unit discharges water vapor through the steam discharge pipe 1, the baffle plate 5 can be manually inserted into the baffle body 2 through the slot 3. The baffle plate 5 is supported by the limiting plate 4. When the water vapor rises to the inside of the baffle body 2, the water vapor is blocked by the mesh-like baffle plate 5. The moisture in the water vapor is adsorbed onto the inner wall of the steam discharge pipe 1 and the baffle plate 5 to form condensate, thus blocking the water vapor and facilitating the subsequent recovery of the condensate. After the condensate is adsorbed onto the inner wall of the steam discharge pipe 1 and the baffle plate 5, the condensate dripping along the inner wall can be collected by the ring-shaped collection tray 8 and flowed to the filter body 10 through the connecting pipe 9. The condensate is further filtered by the filter plate 11 inside the filter body 10 and discharged through the drain pipe 12, thus realizing the recovery of the condensate.
[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 A drain pipe 12 is fixedly connected to one side of the filter body 10. Two sets of drain pipes 12 are provided, and condensate can be discharged through the drain pipes 12.

[0037] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The inner side of the baffle plate 5 is mesh-like, and the mesh-like baffle plate 5 can block water vapor.
[0038] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The collection tray 8 is circular and closely attached to the inner wall of the steam discharge pipe 1. The circular collection tray 8 can be used to collect condensate conveniently.
[0039] The working principle of the unit's effluent recovery system provided by this utility model is as follows:
[0040] First, when the unit discharges steam through the steam discharge pipe 1, the baffle plate 5 can be manually inserted into the baffle body 2 through the slot 3. The baffle plate 5 is supported by the limiting plate 4. When the steam rises to the inside of the baffle body 2, the steam is blocked by the mesh-like baffle plate 5. The moisture in the steam is adsorbed onto the inner wall of the steam discharge pipe 1 and the baffle plate 5 to form condensate, thus blocking the steam and facilitating the subsequent recovery of the condensate. After the condensate is adsorbed onto the inner wall of the steam discharge pipe 1 and the baffle plate 5, the condensate dripping along the inner wall can be collected by the ring-shaped collection tray 8 and flowed to the filter body 10 through the connecting pipe 9. The condensate is further filtered by the filter plate 11 inside the filter body 10 and discharged through the drain pipe 12, thus realizing the recovery of the condensate.
