Hydraulic separators - SPP

Hydraulic separator type SPP can be fitted between a primary liquid circuit and a secondary liquid circuit for examlpe to separate boiler cycle and thermal cycle. Hydraulic separator has been desinged for middle and high power heatting systems consisting of one or many boilers and one or many thermals cycles. Hydraulic separator type SPP ensured independence work those systems without compensate of flow.

Description:

• separates boiler cycle and thermal cycle
• keeps independence fluid flux in boiler cycle and thermal cycle,
• excluded necessity flow compensate boiler cycle and thermal cycle,
• cleans,
• deaerates.

Construction:

Hydraulic separator is made of low-carbon steel and externally painted. On the shell (1) are mounted four pipe connectors. To the inlet and outlet connectors (2) and (3), is connected the boiler cycle. To inlet and outlet connectors (4) and (5), is connected the thermal cycle. Inside the vessel is localized a perforated sreen (6). It prevents flow water from the boiler to the thermal and also increase deaerating effect. For eliminate of air, on the top part of the vessel is connector pipe (7) for connecting deaerating valve. Water passes through division cleaning sreens (9) and exits the outlet. For get rid of pollutions from the Hydraulic separator is connector pipe (10), where is connected a blowdown valve.

Priciple of operation:

Using the Hydraulic separator in a boiler system to separate the boiler cycle from the thermal cycle. Stand out cases:

• the state, where quantity thermal factor on primary side is equal quantity heat received by thermal system (pic.1.). The quantity delivered heat QD is equal quantity heat received QO.
• when demand for heat is lower  QO, the valves on system heat are closing. Part of stream passes along the Hydraulic separator (pic.2). The heat excess QD give back and boiler sensors receive signal to decrease the boilers power or turn off them.
• when demand for heat QO is bigger than heat deliver by boilers QD, the pumps on heating system force return stream (pic.3), by this temperature in thermal cycle is decreasing. Boiler sensor receive signal to increase heat power or turn on next boiler.
