WASTE MANAGEMENT TECHNOLOGY
5
Modern INCINERATION ensures a significant decrease in the waste volume (up to 95%) and is an ecologically clean source of alternative energy (thermal, electrical, steam).
In order to comply with the environmental requirements of the legislation of Ukraine (order of the Ministry of Environment №309 dated 27.06.2006) and provisions of the European Community (Dir2000/76EU, Dir2001/80EU, Dir2010/75EU) the ECO complexes have a 5-stage flue gas cleaning:
Steam or hot water collected in the heat exchange unit may be used for the heating of the premises, in enterprises’ technological processes, or for the generation of electricity. Secondary chamber
Waste loading
Catalytic reactor
acceleration of decomposition of chlorine and fluorine organic compounds, complete neutralization of hardly oxidizing organic compounds, including benzo [a] pyrene, dioxins, furans, etc.
Chemical reactor for gas treatment
flue gases treatment with an alkaline solution to neutralize acidic inorganic compounds of chlorine, fluorine, and sulfur
Bag filter
Thermal recycling under temperatures 850-1100 °C
maximum complete destruction of organic compounds and incineration products oxidizing
Adsorption filter
fine cleaning of flue gases from suspended dust particles to residual concentration not more than 0.01 g/m3 high absorption capacity for a wide range of toxic substances, including: formaldehyde, poly aromatic hydrocarbons, heavy metal compounds, mercury, lead, cobalt, arsenic, vanadium.

Horizontal placement of the flat bags reduces the filter dimensions BY 2.5-3 TIMES comparing with traditional filters
Filtering degree
Residual dust content in the flue gases is no more than 0.01 g/m3
Dynamics of dust and gas movement
Once-through gas circulation (from the top downward) dusts off the bags effectively: • does not lead to the dust accumulation between filtering bags; • does not hinder the filter effective regeneration; • reduces the aerodynamic resistance of the filter BY 1.5 times compared to traditional filters • reduces the engine load of the i.d.fan.
Regeneration
The bag filter regeneration is carried out continuously without disconnecting the filter partially or in full: • Allows reducing the number of filtering bags, which decreases the manufacturing cost and the filter dimensions • Ensures the endurance of the operation of the bags up to 5 years • Reduces the electricity consumption of the compressor due to low air consumption for regeneration • Parameters: Pulse duration 0.1 - 0.2 sec Frequency - 10 pulses per minute Compressed air pressure 500 -700 kPa Compressed air consumption is 0.1 - 0.2% of the cleaned gas amount (air)
Block construction
Allows varying the filter dimension specifications in a wide range and to place the filter of required productive capacity optimally indoors or at the site
Installing
Large-node assembly reduces the installation time of the filter of medium productive capacity (40,000 m3/h). The module size is optimized for convenient transportation via automobile transport.
Maintenance
Easy access to the filtering elements is ensured due to the inspection doors and filter supply with the maintenance site.

CHEMICAL FLUE GASES CLEANING

CHEMICAL FLUE GASES CLEANING (S02, HCL, HF)
• filtering elements of any filtering material, including for cleaning from fibrous, damp, and aggressive substances; • i.d.fan (variable speed fan drive) for transportation of the dust-gas mixture; • compressor for the regeneration system; • horizontal or vertical cyclone that allows reducing inlet dust load and ensuring spark suppression; • air suction valve, low carbon steel chimneys of any diameter and width, shut-off and regulating valves - for connection to the existing flue gases transportation system; • screw feeder for the dust unloading; • in the flameproof design meant for the filtration of the explosive dustgas mixture, including installation in the explosion-hazardous premises, according to DSTU (State Standard of Ukraine) 8828:2019 ‘Fire safety. General provisions’.
The technology of gas cleaning from acidic inorganic compounds constitutes the flue gases processing with the alkaline components by finely dispersing the alkaline solution into the gas path. The alkaline solution may be prepared on spot or supplied to the site in the tank truck, from which it is pumped into the storage tank and, then, the dosing pump supplies it to the nozzles for spraying it into the gas path. The usage of caustic soda in this technological process allows excluding in full formation of dense gypsum sediments in chimneys and equipment elements, which is typical while using lime solutions. S02, HCI, and HF neutralisation processes after the alkaline solution dispersing start in the gas path and finish on the bag filter.
