PURPOSE:
The unit is designed for the treatment of sewage sludge from sewage treatment plants, which has long been stored in the filtration fields, for gas production.
DESCRIPTION:
According to its physicochemical properties, sludge approaches peat. The chemical formula of sludge is C54H212O82N8S7.
Technology stages:
-
- pellet production;
- drying granules;
- thermal conversion of granules by the method of “oxidative pyrolysis”.
During processing, the sludge mass decreases 6 … 8 times. Combustible gas is used to produce heat or electricity in gas piston power plants. Ash can be used as an ingredient for the production of building materials.
TECHNICAL SPECIFICATIONS:
-
- fuel granules with a diameter of 10 … 15 mm;
- drying granules to moisture – 25 … 35%;
- thermal conversion of granules at a temperature of 500-800 C.
As a result of sludge conversion:
-
- the yield of ash on a dry mass of fuel,% – 35-42
- calorific value of the generated combustible gas, MJ / m3 – 5.4-6.9
- gas output, m3 / kg – 0.8-1,2.
ADVANTAGES:
No installation analogues were found. The main advantages of the installation are its mobility, non-waste production and ease of installation.
RECOMMENDED FIELD OF APPLICATION:
Energetics.
RESULTS OF THE RESEARCH:
Ready for implementation.
STAGE OF THE DEVELOPMENT READINESS:
Prototype manufactured.
TRANSFER OPPORTUNITY:
Joint bringing to the industrial level.
NOVELTY:
1 patent of Ukraine.
