Description

Heat power type energy-saving drainage flash tank

Technical Field

The utility model relates to a hydrophobic flash tank field, concretely relates to energy-conserving hydrophobic flash tank of thermal power formula.

Background

The trap is an instrument that functions to separate the vapor and the hydrophobic liquid. The drain flash tank expands and reduces the pressure of drain in a pressure drain pipeline, separates steam and drain, introduces the steam into a heat exchanger or a deaerator, fully utilizes the heat energy of the steam, introduces the drain into a drain tank, and periodically sends the drain into a water supply system, mainly reduces the pressure, if high-pressure steam directly enters a condenser, the overpressure of the condenser is easily caused, and the pressure can be reduced through the drain flash tank, so that the overpressure is avoided.

The mechanical steam trap (free floating ball type, lever floating ball type and inverted bucket type) is switched by utilizing the buoyancy principle, can automatically distinguish steam from water, is usually used for collecting and recycling the water which needs continuous drainage and has larger flow, and is usually used for pipeline drainage or equipment drainage, wherein the lever floating ball type steam trap and the inverted bucket type steam trap have complex structures and simple structures and do not leak steam; the thermal power type (disc type, pulse type) steam trap utilizes the aerodynamic principle, and the pressure drop generated by steam turning is used for opening and closing the valve, is used in places with small flow, large differential pressure and low requirement on continuity, has simple structure and pulse leakage, and is generally used for draining water in pipelines.

The traditional thermal power type drainage flash tank has the defects of low energy utilization rate, high vibration noise and the like, and the market competitiveness of the product is influenced.
