Steam-water ratio regulating valve for steam condensate flash tank

Abstract

The invention relates to a steam-water ratio regulating valve for a steam condensate flash tank. The steam-water ratio regulating valve comprises a steam phase pipe, a water phase pipe and a bubble mixing chamber, wherein the steam phase pipe communicates with the upper end of the bubble mixing chamber; the water phase pipe communicates with the side surface of the bubble mixing chamber; steam enters the bubble mixing chamber through the steam phase pipe; the steam phase pipe and the water phase pipe are both made by adopting a Tesla valve principle; the steam phase pipe comprises a steam feeding pipe, a forward Tesla pipe and a steam discharging pipe which are sequentially connected end to end; the steam discharging pipe communicates with the bubble mixing chamber; the water phase pipe comprises a condensate feeding pipe, a reverse Tesla pipe and a condensate discharging pipe which are sequentially connected end to end; and the condensate discharging pipe communicates with the bubble mixing chamber. By the steam-water ratio regulating valve, liquid level control on the steam condensate flash tank can be conveniently realized, good water drainage and steam blocking effects are achieved, water drops are effectively separated from the steam, the separation effect is obvious, and the quality of the discharged steam during secondary utilization is improved; and meanwhile, in the whole design, electric control is not required, and moving components do not exist, so that the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of steam heat exchange, in particular to a steam-water ratio regulating valve for a steam condensate flash tank. Background technique [0002] The Tesla valve is a one-way conduction valve invented by scientist Nikola Tesla. It has no moving parts and can realize one-way conduction of gas without inputting energy. There is a huge difference between forward flow and reverse flow, and no internal adjustment Mechanical movement uses the space structure to promote the gas flow, accelerates the gas through the physical structure, and reduces the energy loss of the gas during transportation. [0003] In modern industrial production, a large amount of waste steam is often produced, and these high-temperature and high-pressure waste steam are often directly discharged into the atmosphere, resulting in a large amount of heat loss, insufficient utilization of waste heat, and harmful effects on the environment.

Problems solved by technology

[0003] In modern industrial production, a large amount of waste steam is often produced, and these high-temperature and high-pressure waste steam are often directly discharged into the atmosphere, resulting in a large amount of heat loss, insufficient utilization of waste heat, and harmful effects on the environment. It will cause pollution. In order to prevent steam pollution and loss of waste heat, waste steam is usually recycled, but waste steam usually carries mist water droplets and cannot be directly recycled.

[0004] In the existing steam heat exchange system, the requirements for pressure and explosion-proof level are relatively high, and the liquid level control of the steam condensate flash tank is relatively difficult, resulting in low separation efficiency of water droplets and steam during the conversion process, and when When the separation space is limited, it is difficult to guarantee the output of qualified dry saturated steam
