Filtration test (18.12.2023)

In this test, we adhere to the test specification (01 Test Specification of the Filtration System) by inspecting each and every component of the filter system to ensure its functionality.

First, we double-checked the mechanical components, such as the ball valves, ducts, and piping system from the chemical filter and scrubber to the chemical and water supply tanks, to ensure that everything was properly linked.

Second, we used the GUI software to inspect the electrical connections for each item, such as pumps, air supply fans, and exhaust fans. Each device was checked for functionality for 10 seconds

Third, we discovered that the garbage bags had become wet as a result of the rain; therefore, instead of the waste bags, we used bags filled with wood.

Fourth, we examined the manual flame igniter and discovered that it was not working properly due to a malfunction in its electric parts, and the trailer of the powerplant was also not steady and was inclined, preventing the tank from pushing the Dizel to the flame igniter.

Fifth, we used the GUI software to open the exhaust fans and the air supply fans, then we manually started the fire through the main gate, and when the fire started, we closed the main gate.

Sixth, we begin collecting data for the temperature at the incinerator outlet, the temperature between the chemical filter and the scrubber, and finally the temperature in the electro-filter inlet.

Seventh, we collected data on T1, T2, and T3 sensors when P1 and P2 were closed, when P1 and P2 were opened, when P2 was closed, and finally when both P1 and P2 were opened together again.

Eighth, we used the GUI software to close the pumps P1 and P2, the exhaust fans E1 and E2, and the air supply fans AF1 and AF2, while manually closing the ball valves BV1, BV2, BV3, BV4, and BV5. to put out the fire, and we double-checked that all systems were turned off.

Graph of the Temperature Sensors 

Guide:

From 0 to 1, the Table system was in rest.

From 1 to 5, Pumps P1 and P2 were closed.

From 5 to 15, Pumps P1 and P2 were opened.

From 15 to 25, pump P2 was closed and P1 was opened.

From 25 to 33, P2 was opened again when P1 was already opened.

 

Test Analysis

  • The flame igniter had difficulty since the trailer became inclined due to rain and sank backward to the ground, preventing the fuel from feeding the flame igniter.
  • Both pumps P1 and P2 assisted the flue gas in lowering the temperature when it reached values between 74 and 94 degrees Celsius; it was not enough, but it did a nice job in comparison to the previous test results.
  • The chemical filter performed well in the filtration process and in cooling the flue gases, but this was not permanent because the drainage of the chemical filter was connected to the main hole of the chemical, so it was fed again, causing its temperature to rise to 60 degrees Celsius, reducing the cooling process of the flue gases.
  • The new sprinklers did a better job of chilling the flue gas with less water and chemical supplies than the old standard method. 
  • The cleaning procedure was improved by the addition of cyclone number one.
  • Adding an extra temperature sensor to the filtering cycle improves data collection accuracy.
  • Connecting the GUI software in the room close to the engine trailer rather than the far-distant center improves data transmission speed.

What should we do next?

  • Repairing the flame igniter and connecting it to the graphical user interface software.
  • Maintain the trailer's stability on the ground.
  • Increase the cooling process with the chemical filter and get a bigger water tank.
  • Re-cool the flue gas with the scrubber drainage water.
  • Including additional methods to get the flue gas to the required temperature.
  • Using fewer trash bags instead of 12 bags to avoid a dramatic spike in temperature.
