High temperature steam cooling system

Abstract

The invention discloses a high-temperature steam cooling system. The high-temperature steam cooling system comprises a heat exchanger and a steam cooler, wherein the heat exchanger is connected with the steam cooler through a steam pipe and comprises a heat exchanger steam inlet, a water tank, a condensation pipe and a heat exchanger steam outlet; the steam cooler comprises a zigzag cooling pipe bundle which is connected with the steam inlet; a certain included angle of + / -3 degrees to 9 degrees is formed between the cooling pipe bundle and the horizontal direction; a spraying pipe is arranged above the cooling pipe bundle; a plurality of atomizing nozzles facing the cooling pipe bundle are arranged on the spraying pipe. The heat exchanger is used for pre-cooling steam, and hot water is formed by absorbed heat and enters the subsequent process, so that the aim of saving energy is achieved. The steam cooler is used for fully cooling the steam through air and water to enable the steam to completely become liquid with specified temperature. The high-temperature steam cooling system has the characteristics of small water requirement, obvious water saving effect, non-consumption of the steam and the like.

Description

technical field [0001] The invention relates to a heat exchange system, in particular to a cooling system for high-temperature steam. Background technique [0002] Due to population expansion and economic development, water shortages are occurring in many parts of the world, especially in cities. Cooling equipment is a large industrial water consumer, water consumption accounts for 70%-80% of industrial water consumption, and indirect cooling water accounts for 70-80% of cooling water. It is under such circumstances that evaporative cooling technology has emerged as the times require and has become one of the important technologies for water recycling. Since the specific heat and latent heat of vaporization of water are much larger than the specific heat of gas, the cooling effect of evaporative cooling is more significant and saves water resources. [0003] Compared with the dry air cooling, the wet air cooling is developed on the basis of the original dry air cooling and...

Problems solved by technology

This structure can well realize the cooling of high-temperature steam, but in the actual operation of the cooling system, the following problems were found: Although the heat sink structure can help to enhance the heat dissipation effect to a certain extent in the early stage of system operation, the system operation After a period of time, impurities and scale are easy to accumulate on the heat sink structure and cooling pipes, which will reduce the heat dissipation effect of the system, and it is necessary to stop regularly to clean the heat dissipation system
