Principles of Operation - Triton Liquid Ring Blowdown System

(Click the downloadable pdf for annotated pictures)

The proprietary Triton Liquid Ring Blowdown system transforms a Triton vacuum into a unit that is capable of also discharging collected liquids under pressure, in the same manner as a vacuum truck.  A 4-way valve allows the mode of operation to be changed between vacuum and pressure.  The pump still turns the same direction and creates airflow; only the direction of airflow is changed via the 4-way valve to allow the airflow to be used for either vacuum suction or pressure blowdown.  Note how the valve has two passages that simply connect adjacent ports, and changing the orientation of the valve controls where the air intake comes from and where the compressed air is delivered.

There is a 3” Pressure Safety Valve on the water tank that is set to lift at 20 psi.  There is a backup 2” Pressure Safety Valve on the cyclone that lifts slightly higher.

This system is designed to allow the blowdown under pressure of liquids collected in a tank.  For vacuum operations, the working end of the hose would connect to the intake on the collection tank, and the airflow would then be hosed to the intake of the Triton vacuum unit at the cyclone.  For pressure blowdown operations, the intake valve on the collection tank would need to be closed, the bottom drain opened, and the position of the 4-way valve changed from “vacuum” to “pressure”.  See Operating Instructions in the next section, as well as the illustration.

For safe operation, the 4-way valve should be turned half way between vertical and horizontal, to the “neutral” position, and allowed to stabilize before shifting to the opposite operation mode.  Also, be aware that the drain hose on the collection tank will be pressurized, so it should not be allowed to whip free.  Pins should be in place on the ears of camlock fittings and hose ends should be tied off to prevent accidental separation and to prevent whipping.

Operating Instructions:

Startup Procedure

1.     Ground machine before starting.

2.     Open the ¾” valve on the bottom of the water tank labeled Primer Valve.

3.     Fill the water tank to the center of the sight glasses on the water tank.

4.     Check all hoses on the unit to ensure there are no cracks or leaks.

5.     Make sure all camlocks on the unit are completely tight and latched. Make sure all safety pins are in place.

6.     Tighten all wing nuts on the cyclone and water tank.

7.     When the water level has reached the center of the sight glasses, close the ¾” Primer Valve.

8.     Open the 6” Butterfly Valve “Vacuum/Pressure Break” on the top of the cyclone.

9.     Make sure the 4-way valve on the top of the water tank is in neutral or vacuum position only.

10.  Make sure the vent/exhaust pipe above the 4-way valve is not blocked or covered.

11.  After all procedures have been completed, start the unit by pushing the green button on the start box.

12.  Once the unit reaches maximum speed, close the 6” Butterfly Valve.

During Operation

To prepare to change from vacuum suction to pressure blowdown mode, close the intake and open the exhaust drain on product collection tank. To change between vacuum and pressure mode, position the 4-way valve to neutral for 15 seconds before shifting into pressure mode. Reverse this sequence to switch back to vacuum mode.

Shutdown Procedure

1.     Open 6” Butterfly valve “Vacuum/Pressure Break” to minimize pressure or vacuum.

2.     Shutdown the unit by pressing the red button on the control box.
