HANTECHAIRNOZZLE

Direct cleaning air along the bag axis

Our nozzle development focuses on directing the primary jet along the bag axis and entraining secondary air through side openings. A replaceable design with a suitable collar supports blowpipe installation and service access.

Differential-pressure cleaning and correct nozzle alignment are considered together to achieve the required cleaning effect with more controlled compressed-air use. Fit is assessed against blowpipe, nozzle, venturi and bag geometry.

Air savings are determined by comparative measurement under equivalent process conditions while maintaining cleaning performance. The nozzle is in development; no numerical saving rate has yet been validated.

Benefits for your process

We define the required outcome with you

Differential-pressure guarantee

We define the filter pressure-drop range together with gas flow, dust loading and cleaning settings. Acceptance measurements refer to agreed steady operating conditions.

Emission guarantee

Outlet dust concentration, gas reference conditions and the measurement method are defined in writing in the proposal.

Bag-life guarantee

Media selection and warranty duration are established for the project, based on temperature, chemistry, moisture, abrasion and operating conditions.

Flow and distribution assurance

Guaranteed flow, system resistance and measurement locations are defined together. Gas distribution and interstitial velocity are included in the design checks.

Guarantee values and durations are established in the project proposal against agreed process data, operating limits, maintenance conditions and acceptance testing.

Field inspection

Fluorescent powder leak testing

Original test photographs from our archive. Tracer powder, UV inspection and location-specific records are used to inspect bags, seals and tubesheets for leaks.

Smart differential-pressure control

Cleaning starts and stops according to the pressure difference across the filter. Threshold and cycle settings reduce unnecessary pulses and control compressed-air consumption.

Online cleaning

Bags are cleaned sequentially while gas continues to flow. Pulse duration and intervals are adjusted to dust loading and the differential-pressure trend.

Offline cleaning

The compartment being cleaned is isolated while the others continue filtering. Isolation and settling time are engineered to limit dust re-entrainment.

Balanced gas distribution

Inlet distribution and compartment loading are coordinated. Interstitial velocity and internal gas distribution are assessed to reduce abrasion and uneven loading.

Maintenance and bag life

Media, cages, cleaning settings and access are selected together. Appropriate cleaning frequency and service access help protect bag service life.

Traceable operation

Differential-pressure trends, cleaning cycles and alarm thresholds can be monitored. Commissioning measurements establish cleaning settings and the maintenance plan.
