Built-in direct-discharge type vapor-liquid phase change nozzle combination module

Abstract

The invention provides a built-in direct-discharge type vapor-liquid phase change nozzle combined module. The built-in direct-discharge type vapor-liquid phase change nozzle combined module comprises a cylindrical module body, wherein an equal-diameter direct-discharge through hole and a plurality of nozzle through holes arranged in the circumferential direction are formed in the module body; and the nozzle through holed sequentially comprise bowl-shaped grooves communicated with one another, throat measuring holes with different diameters and a liquid outlet spraying flow channel from top to bottom in the vertical direction. According to the built-in direct-discharge type vapor-liquid phase change nozzle combined module, an adjusting handle can be rotated at any time to adjust the diameter of a nozzle so as to change the condensate displacement change of an energy saver according to the change of the condensate load of steam equipment, so that the condensate displacement change is reasonably matched with the equipment working condition and the actual condensate load all the time, condensate is timely discharged, and meanwhile, steam loss can be effectively prevented, and the process temperature and the process pressure are ensured.

Description

technical field [0001] The invention relates to the technical field of steam traps, in particular to a built-in direct discharge vapor-liquid phase change nozzle assembly module. Background technique [0002] As an important part of the industrial heat pipe network system, the steam trap plays a vital role in the heat exchange of industrial steam. Because only steam is needed on equipment that uses steam, and this kind of heat-using equipment will definitely produce condensed water during heat exchange, condensed water will absorb steam energy and reduce steam quality, reduce steam enthalpy and improve heat exchange rate As it falls, the condensed water becomes a harmful fluid, and at the same time it is mixed with air and other non-condensable gases, which becomes the cause of equipment failure and performance degradation. [0003] The vapor-liquid phase change nozzle combination module is one of the core components of the steam-water separator or the high-efficiency steam...

AI Technical Summary

Problems solved by technology

[0003] The vapor-liquid phase change nozzle combination module is one of the core components of the steam-water separator or the high-efficiency steam economizer. Due to the change of the working conditions of the heat-consuming equipment, the displacement of the heat-consuming equipment per unit time has obvious differences, and the traditional steam trap cannot adjust the discharge. Due to the influence of temperature, pressure, water quality, corrosion and many other factors in the working environment, the traditional manufacturing process and materials of the vapor-liquid phase change nozzle module can no longer meet the needs of industrial production, and cannot be timely The output of condensed water leads to blockage and lower steam quality, or leakage of steam causes steam pressure release and loss of steam enthalpy, which directly affects production efficiency and increases maintenance costs, and also causes waste of steam resources
