[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a waste heat recovery device for a power plant condensate system, including a condenser 1. A water supply tank 103 is symmetrically fixedly connected inside the condenser 1. A cooling tank 104 is installed on the side surface of the symmetrically arranged water supply tank 103. An air outlet pipe 402 and a water outlet pipe 303 are fixedly connected to one end of the condenser 1. The water outlet pipe 303 is fixedly connected to the other end of the water supply tank 103. A preheating water pipe 304 is connected to one end of the water outlet pipe 303 through an installation component. A water outlet 301 is provided at one end of the preheating water pipe 304. A filter component is fixedly connected to one end of the air outlet pipe 402. An air pump 401 is installed above the filter component. An air inlet pipe 4 is fixedly connected to the upper end of the air pump 401. A heating pipe 305 is fixedly connected to one end of the air inlet pipe 4. The heating pipe 305 is wound around the side surface of the preheating water pipe 304.

[0019] As a technical optimization of this utility model, the installation component includes a flange 307. One side of the flange 307 is fixedly connected to the other end of the preheating water pipe 304. The other side of the flange 307 is fixedly connected to a bend joint 302. One end of the bend joint 302 is connected to the outlet pipe 303 through a water collection tank, which facilitates the transportation of cooling water from the water supply tank 103 and the cooling tank 104 to the boiler for heating, thus avoiding the waste of water resources.

[0020] As a technical optimization of this utility model, a gas pump 2 and a water inlet pipe 101 are fixedly installed at the other end of the condenser 1. One end of the water inlet pipe 101 is fixedly connected to the other end of the water supply tank 103, and a water valve 102 is fixedly installed on the side surface of the water inlet pipe 101.

[0021] As a technical optimization of this utility model, the cooling tank 104 fixedly connected to the side surface of the water supply tank 103 is staggered, so that the steam input by the air pump 2 can be cooled and condensed for a longer time, and at the same time, the cooling water inside the water supply tank 103 and the cooling tank 104 can be heated better.

[0022] As a technical optimization of this utility model, the filter assembly includes a filter box 405, a filter plate 403 is slidably installed inside the filter box 405, and a support rod 404 is fixedly connected to the side surface of the filter box 405. One end of the support rod 404 is fixedly connected to the condenser 1. The filter box 405 and the filter plate 403 can further filter the moisture in the steam.

[0023] As a technical optimization of this utility model, a heat insulation cover 3 is provided on the side surface of the preheating hot water pipe 304, and heat insulation cotton 306 is fixedly connected to the inner surface of the heat insulation cover 3. The heat insulation cotton 306 inside the heat insulation cover 3 can further insulate the water inside the preheating hot water pipe 304, reduce the heat loss of the water inside the preheating hot water pipe 304, and further reduce the waste of thermal energy.

[0024] In use, this invention first opens the water valve 102 on the side surface of the inlet pipe 101 and simultaneously starts the air pump 2. At this time, the inlet pipe 101 injects cooling water into the water supply tank 103 and the cooling tank 104. Meanwhile, the air pump 2 inputs high-temperature steam discharged from the turbine into the condenser 1. The high-temperature steam is then cooled and condensed into water by the water supply tank 103 and the cooling tank 104 inside the condenser 1. Simultaneously, the high-temperature steam heats the water inside the water supply tank 103 and the cooling tank 104. Finally, the water from the water supply tank 103 and the cooling tank 104 flows through the outlet pipe 3. Water 03 and water outlet 303 enter the preheating water pipe 304. Water is then transported to the boiler for heating through the water outlet 301 at one end of the preheating water pipe 304. This reduces the boiler's water heating time and improves the water heating efficiency. At the same time, the air pump 401 is started, which will draw out the hot air inside the condenser 1. When the gas passes through the filter box 405, the moisture in the hot air will be further filtered. After that, the filtered hot air will enter the heating pipe 305 through the air inlet pipe 4, and the heating pipe 305 will further preheat the water inside the preheating water pipe 304.
