Four-effect condensation dehumidification drying technology is an advanced sludge drying reduction technology. It has significant advantages such as lower air outlet temperature, better drying capacity and efficiency, and more economical operating costs; adopts "four-effect condensation dehumidification and drying" equipment, and the comprehensive dehumidification performance ratio (SMER) is as high as 4kg.H2O/kw.h or more , The moisture content of dry mud is reduced to 10%-30%, which is more than 50% energy-saving than traditional low-temperature drying, which is twice the industry standard.

 

2.The daily dehumidification and water removal capacity of a single device ranges from 200 kg to 50 tons, and all models can meet;
 

3.Electric energy can be used directly, or energy such as steam and waste heat can be used;
 

4.It can be “centralized treatment” or “decentralized treatment” to meet the requirements of sludge disposal policies in different regions;
 

5. It is not affected by the external environment temperature (low temperature in winter) and humidity (humidity in summer), suitable for use in various regions;

 

2. During the drying process, the oxygen content is less than 12%, the dust concentration is less than 60g/m3, the particle temperature is less than 70℃, and there is no danger of dust and explosion;
 

3. The sludge is statically spread, and there is no mechanical electrostatic friction with the contact surface;
 

4. There is no "sticky phase" stage of the urban sludge drying process (about 60%);
 

5. The dry material is in granular form and there is no danger of dust;
 

6. The discharging temperature is low (<50℃), no cooling is needed, and it is stored.

 

2. There is no loss of organic components in the drying process, and the dry material has a high calorific value, which is suitable for later resource utilization;
 

3. The reduction can be as high as 80%, which can save a lot of later transportation costs; 

 

4. Using Pasteur (pasteurization) sterilization method-low temperature heat sterilization, the drying temperature is above 70 ℃ for 90 minutes to 120 minutes, and the effective sterilization is as high as 90%;

 

2. 80% wet mud is dried to 60% per ton, and the comprehensive power consumption is 125kw.h;

3. 80% wet mud is dried to 10% per ton, and the comprehensive power consumption is 200kw.h;

4. 4 kg of water can be removed per 1 kilowatt-hour of electricity (the dehumidification performance ratio is 1:4kg.H2o/kw.h);

 

2. Using low temperature drying process, the amount of H2S and NH3 precipitation is greatly reduced;

3. Condensate (sludge moisture) is easy to dispose of and can be discharged directly;

4. Adapt to sewage plants in urban areas, villages and scenic spots;

 

2. It can be installed in the basement to save land area;

3. No complicated civil structures and infrastructure, saving civil construction costs;

4. The equipment is simple to install, and the installation and debugging cycle is short, saving time and cost;

 

2. "PLC+touch screen" intelligent control can realize remote centralized control;

3. The moisture content of the discharge material can be adjusted arbitrarily (10%-50%);

 

2. There is no mechanical wear during operation, and the service life is more than 15 years;

3. No vulnerable and consumable parts, easy to use and manage;
