Supply of two bag filter units to capture particle emissions from the Ln-8000 unit flow drying system

of Qu =50,000 m3/h.

The supply of 2 modules sized for a flow rate of Q = 25,000 m3/h is planned, as well as the support structure, access ladder and the hoppers connecting both modules for both the inlet of dirty air and the outlet of clean air to the fan.

Given the temperature and humidity of the gases to be filtered, the filter material will be composed of punched Ryton sleeves.

Operation:

JET-FILTER systems incorporate rows of filter bags suspended from a metal support. Dust-laden air enters the filter through its lower section (the settling hopper). The coarsest particles are deposited in this hopper. The remaining dust, along with the air, reaches the outside of the bags, settling there. When the cleaning system is activated, the dust is detached from the bags and deposited in the settling hopper. The dust is discharged via an auger and honeycomb valve, located at the base of the discharge hopper and driven by gearmotors of 2 and 0.5 HP, respectively.

 

All the electrical equipment for command, control and regulation is distributed over the electrical cabinet.

The enclosure is a metal cabinet with IP55 protection, epoxy paint and mounted on a plinth, which isolates it from the ground.

The electrical circuit starts at the main switch. From there, it passes to a distribution busbar, where power is supplied to the various circuits, protecting each motor with circuit breakers.

The output to the motors is located at the bottom, distributed in a terminal block.

All control operations are carried out at 24 V, with operating signals and thermal tripping for each of the motors.

Temperature regulation is done through a closed loop, composed of the following elements:

PT-1200 probe, placed on the gas outlet of the trommel.

Records the working temperature.

Microprocessor-based programmable temperature controller with presetting, sensitivity adjustment, and ramp times. It is equipped with under- and over-temperature alarms.

ABB brand electronic speed controller in rotary cylinder, VTI main draft fan.

Progressive starters on the cyclone dust collection motor and the drop chamber motor.

Vega brand depression and safety probes to visualize the depression in the drying system.

Siemens brand PLC.

MAIKONTROL brand probes.

High-efficiency Siemens brand equipment motors.

It is the element responsible for collecting the solid product once dry, and is responsible for decanting the moisture-saturated gases to conduct them to the chimney. It is made of carbon steel sheet and has anti-wear working temperature probes attached.

The chamber is completed by a 450x350 auger with progressive helices to collect the finished product, anti-wear.

It is the duct that carries the vacuum cleaner outlet to the outside.

Constructed from carbon steel sheet, cylindrical in shape with a length of 15,000 mm and a diameter of 1,100 mm, with reinforcing propellers on top.

It is screwed to the ground using studs, in the foundation of the plant.

It is provided with a drainage inlet (condensation, rain, etc.), an inspection and cleaning door at the bottom, and sample collection ports with access to the samples.

The chimney is made entirely of H-II quality carbon steel in thicknesses of 8 to 5 mm in all its sections.

The vacuum creates an air current that flows through the entire system, initially heating it in the oven, evaporating some of the water contained in the product, and drawing the steam from the rotating cylinder toward the cyclones. It then escapes into the atmosphere through the chimney.

The vacuum cleaner is driven by a 150 HP direct drive motor with a suction power of approximately 50,000 m³.

It is mounted on a metal chassis and supported by a sinenblok of virgin rubber to prevent vibration transfer during operation. The fan is made entirely of 304L stainless steel.

These elements are responsible for conveying moisture-saturated air from the dry product drop chamber to the gas evacuation chimney. They are made of 4 mm carbon steel sheet, with a motorized flap between the aspirator and the cyclones regulating the airflow within the system. The ducts are heat-exhausted and made of wear-resistant material.
