Acoustic Cleaning

Keep Surfaces clean...

Stacks Image 286

Since 21 years Hartge stands for professional support in relation to all aspects of acoustic cleaning: From detailed analysis via our consulting service through to professional realization. In doing so, we associate precise handcraft with state-of-the-art techniques and fulfill the highest quality demands.

Caused by acoustic sound waves small parts of ashes and dusts will be put in vibration or kept in motion. Thus, claggy deposits will be prevented. For newly erected plants you better speak of ‚keeping clean‘ the system. As acoustic sound waves expand spherically, they can reach even the rear side of complex structures by reflection.

Acoustic cleaners were applied in the following branches: Biomass, pit-coal and lignite power plants Paper industry, chemical industry, food production, etc. These plant sections are favored: Economizer, air preheater, silo, hopper, filter systems, DeNO x (SCR), superheater

Economizer

Installation of the acoustic cleaner in flue gas direction above each bundle. The sound cleaners take over 100% of the cleaning of the ECO. With a lot of ash load (for example: waste paper sludge incineration) the sound cleaning supports the existing cleaning procedures. Easy installation! All you need is a 300 mm opening in the eco-wall. The amortization is less than 2 years.

BAG FILTER

Thermal power plants, chemical and food industry, anyone who has to filter something ... Deposits in the funnel and hopper should be prevented. The hopper stays clean. Sound helps to clean the hoses. The jet pulse can be reduced between 30% and 70%. The service life of the hoses is extended accordingly. Fast amortization. Install an acoustic cleaner at the top of the funnel, keeping the hoses.

ESP

Thermal power plants and all who need to filter something. Deposits in the hopper and bridging should be prevented. Rappers are supported or replaced.

  • Hopper: Installation of an acoustic cleaner at the top
  • Plates: Installed on the funnel and on the roof of the E-filters
  • Baffles: installation at inlet E-filter in front of the hole / baffle

The sound cleaners take over the cleaning of the hopper of the plates and the perforated plate.

SCR

All plants with low-cat or high-cat. The commonly installed sootblowers usually do not reach all points, so that enforce parts of the catalyst. Installation of acoustic cleaner above each level, which is equipped with catalysts. The sound cleaners take over 100% of the cleaning of the catalyst Due to the relatively low temperatures, the cleaning performance of the horns is about 10 meters. If you load from two sides, even very large systems can be cleaned. (20m x 20m). The cleaning of Katy layers with sound is today the state of the art!

SH

All thermal power plants with ash-containing flue gas At very low melting points of the ash, such as in the combustion of waste wood, the superheater sets are very fast. Often this does not achieve the desired travel time. Installation of acoustic cleaner before each bundle. The sound cleaners support the standard cleaning process. Installation in manhole or a bend. The goal is to extend the travel time. By reducing the service life results in a very fast amortization.

Silos

Chemistry, waste incineration, biomass power plants, paper mills, coal-fired power plants

  1. Silo cleaning
  2. Destruction of bridges

For silo cleaning, a sound cleaner is installed on top of the roof. Deposits on the silo walls are solved. In some cases, this position also works in bridging. To destroy bridges, the sound cleaner is attached to the bottom of the funnel With little effort, the purpose is fulfilled. On the roof is sufficient a 300 mm opening. The funnel requires a flange construction

Ventilator

Installation of the sound cleaner on the vacuum side. The scoop remain without covering. As a result, no caking ends can break loose and thus cause the fan to vibrate.

Portfolio

Hartge Schallreinigung offers different variants of sonic cleaners with different frequencies and outputs.

  • Design: straight or 90° curved
  • Generation of sound waves: by means of compressed air or electric drive
  • Material: 1.4308, P265GH or according to customer requirements
  • Frequencies: 60, 75, 100 and 250 Hz (compressed air) 30 - 100 Hz (electric)

The modular design and the use of different materials enable us to offer the right solution for every installation situation. Of course, we also offer special solutions: other materials, special alloys for HT areas and coatings against the risk of corrosion. The construction of prototypes serves the continuous improvement of our systems.

Thanks to this diverse range, we can guarantee installation for almost any situation on site.

Test our System

No power plant is like the other!

Predictions for acoustic cleaning as a one hundred percent successful means of maintenance aren’t possible. The cleaning of defined plant sections from ashes and dusts depends on many complex factors. It’s therefore why universities and companies (by internal research) give strong effort to this aspect. They try to improve and new approaches will be carried out.

That’s where we will support you: We offer you to rent an acoustic cleaning equipment (operating with compressed air) for testing. In consultation with you, we’ll fix the duration of the test corresponding e.g. to the location of installation. When acquiring, costs for testing will be taken into account.

In advance, we’ll decide thoughtfully on type, number and location of the sonic horns to install. Installation is up to you, we’ll be responsible for setting-up the system. During the testing, you can contact us at any time to receive the best results by optimal settings based on your initial experiences.

Netzwerk

Strong partners at our side are:

Häuser & Co. GmbH from Duisburg

They specialise in coatings against corrosion and wear, both in the high-temperature range and when temperatures fall below the dew point. Using plasma and laser spraying processes ("LaserCladding"), materials and coatings are applied that are specially tailored to the stresses in the area of evaporator and superheater heating surfaces and can significantly increase the service life and availability of your systems.
