The cement and mineral industries all have production processes that involve fusion: rotary kiln, shaft kiln, industrial electric furnace, etc. NEU has all of the necessary know-how to support your projects, thanks to its multiple product items.
Fabric filters are working at flue gas temperatures of up to max. 240°C.
Therefore it will often be necessary to install a cooling stage upstream fabric filter.
The additive powder injection serves, as far as necessary, for the separation of acid crude gas components (HF, HCl, SOx) and for the corrosion protection.
The reliable observance of the corresponding requested emission limit values, for particles, heavy metals, acid crude gases such as HF, HCl, SOx and dioxins/ furanes
The selection of a filter fabric quality and by this the setting of the flue gas temperature within the filter is subject to the requirements of the corresponding application. It is influenced among other things by: gas composition, separation of heavy metals, separation of acid crude gas components, acid and water dew point, investment and operating costs.
The service lives of the filter bags installed in fabric filters downstream glass tanks total to at least two and well above five years. Condition for this is the selection of a filter type with gentle treatment of the filter fabric.
Contamination of the air is a major issue in the cement and mineral production industries. Smoke treatment systems are universally present for these processes, as suspended particles, metal or gas oxides may cause respiratory issues.
There are varied “turnkey” solutions provided by Delta NEU. From smoke extractors to industrial smoke treatment installations above an electric smelting furnace, Delta NEU implements its technology and products to prevent risks.
On a cement and mineral production kiln, both technologies share the same issue: high temperatures, very fine dust particle size, presence of acids in gaseous state.
Moreover, smoke extraction and filtration is a technique that combines dust particle extraction (metal oxides such as cadmium, chromium, copper, nickel or cobalt) and the filtration of pollutant gases (HF, HCL, etc.). To achieve this, the smoke is neutralised through the injection of a neutralising agent into our dust extractors
