[0002] Deaerator exhaust gas waste heat recovery is a common energy-saving technology in thermal power plants or other industrial processes. It is mainly used to recover the waste heat in the exhaust gas discharged by the deaerator and use it for preheating feed water or other purposes to improve the energy efficiency of the entire system. In the exhaust gas waste heat recovery process, the exhaust gas discharged by the deaerator passes through the heat exchanger, the temperature is reduced, and the steam part of it is condensed into water. This part of condensed water is usually discharged together with other wastewater in the feed water system. The discharged wastewater needs to be properly treated to ensure that it meets environmental protection standards. The existing discharge equipment uses direct discharge. When a large amount of wastewater is discharged at the same time, the pressure at the discharge point is relatively high and the practicality is poor. Utility Model Content

[0016] The drain pipe 2 is fixed by the concrete wall 1 to ensure the discharge position and discharge stability of the drain pipe 2. The wastewater is discharged through the drain pipe 2, and the turntable 3 can block the drainage of the drain pipe 2. At the same time, three openings 4 are evenly arranged on the turntable 3, and the drain pipe 2 can be opened intermittently to ensure the drainage effect. Through the coordinated use of the turntable 5 and the baffle 6 and the motor 7 and the lever 8, the equipment can achieve intermittent drainage effect during the drainage process. At this time, through the coordinated use of the cooling sleeve 11, the discharged wastewater with residual heat can be cooled and discharged intermittently. At the same time, it can effectively avoid the processing pressure on the discharge point when a large amount of wastewater is discharged, thereby ensuring the rationality of the discharge and the discharge effect.

[0017] It also includes a plurality of wedge blocks 10 and a clamping structure 8. The plurality of wedge blocks 10 are evenly fixed to the outer wall of the turntable 3. The side wall of the concrete wall 1 is fixedly equipped with the clamping structure 8. The clamping structure 8 clamps the wedge blocks 10.

[0018] The clamping structure 8 includes a support plate 81, which is fixedly installed on the side wall of the concrete wall 1. A sliding rod 82 is installed through the inner wall of the support plate 81, and a clamping block 84 is fixedly installed at the end of the sliding rod 82. A spring 83 is sleeved on the outer wall of the sliding rod 82, and a rubber sleeve 85 is sleeved on the outer wall of the spring 83. One end of the rubber sleeve 85 is connected to the clamping block 84, and the other end of the rubber sleeve 85 is connected to the support plate 81.
