Waste gas heat recovery condensation system

Abstract

The invention discloses a waste gas heat recovery condensation system. The system comprises a steam trap, a condensate water tank and condensate water pumps; the input end of the steam trap is used for receiving steam of a waste gas system; the output end of the steam trap is connected with a condensate water conveying valve through a connecting pipeline; the output end of the condensate water conveying valve is connected with the condensate water tank and penetrates through the condensate water tank; a magnetic turning-plate liquid level meter is arranged in the condensate water tank; a support is arranged under the condensate water tank; a pressure water pipe is connected with the lower part of the condensate water tank and penetrates through the lower part of the condensate water tank;and two ends of the pressure water pipe are respectively connected with the condensate water pumps through pipes. Waste gas condensate water with heat energy is recycled into the condensate water tankthrough a pipeline for reuse, and damage of the condensate water to the parts inside the condensation system is reduced. A closed type recycling mode is adopted in the whole recycling pipe network, so that a large amount of steam can be saved, pollution to the environment can be reduced, and occurrence of intermediate breakdown is avoided. In addition, the structure is simple, maintenance can beavoided, and safe and reliable operation of equipment can be guaranteed.

Description

technical field [0001] The invention relates to the field of condensation systems, in particular to a waste gas heat recovery condensation system. Background technique [0002] The exhaust gas heat recovery condensing system is the main component of the exhaust gas refrigeration device. Most of the various cold storages built in China before the 1990s used water-cooled condensers, and most of the vertical water-cooled types also had some air-cooled condensers. In the 20th century After the 1990s, especially in newly built or renovated cold stores in recent years, the use of evaporative condensers has gradually increased. However, the existing condensing systems for waste gas heat recovery still have the following shortcomings: [0003] For example, the application number is 201710425571.3, and the patent name is an invention patent of an exhaust gas heat recovery condensation system and its exhaust gas treatment method: [0004] Its waste gas treatment methods include high ...

AI Technical Summary

Problems solved by technology

[0006] (1) The condensed water produced after the existing exhaust gas heat exchange cannot flow smoothly to the water collecting tank, the water hammer generated in the condensing system will cause serious damage to the coil, and the condensed water in the main pipe network will flow back into the water collecting tank to cause the condensation system Hydrophobic failure;

[0007] (2) Due to the complex structure of the steam trap inside the existing condensing system, there are moving parts in the valve, which makes its work reliability poor. Once the steam trap fails on site, it is also very difficult to identify and repair. If the steam traps cannot be replaced in time, it will cause a large amount of steam leakage at some steam traps, which will intensify the waste of energy and resources.
