Static Mixer Series

1. Product Characteristics

SQS series steam-water mixer is a new energy-saving and environmental protection product. It uses steam and water to heat water directly. It has the characteristics of low noise, no vibration, high heat exchange efficiency and energy saving. It is widely used in domestic and production hot water heating and thermal deaeration systems. The heater mainly consists of nozzle, shell, mesh plate and gasket. When heated water passes through a Lall-shaped nozzle, steam sprays into the water from the outside of the nozzle through many oblique orifices on the wall of the nozzle. The two mix well instantaneously in high-speed flow to achieve the purpose of heating.

For different types of heaters, at rated flow rate, the steam required to heat hot water at different temperatures can be calculated by the following formula: D0 = D1C1 (T2-T1)/(i''0-C2T2)= D1 (qT2-qT1)/(i'-Ct2)

In the formula: D1 - rated flow rate (t/h) C1 - specific heat of water at T1 temperature (kJ/kg. C)

D0 - required vapor volume (t/h) C2 - specific heat of water at T 2 temperature (kJ/kg. C)

T2 - Water temperature after heating () T1 - Water temperature into heater ()

I''0 - Enthalpy of saturated steam entering heater at pressure P0 (KJ/Kg)
