The new energy sludge drying system is mainly a complete set of processes and systems for efficient and low-cost drying of sludge using solar energy, reclaimed water thermal energy and multiple heat sources, mainly including solar greenhouses, automatic sludge feeding units, and automatic paving units , Automatic feeding and conveying unit, intelligent heating unit, exhaust gas treatment unit and automatic control unit and other subsystems. This system solves the "three highs" problem of high investment, high energy consumption and high cost in the sludge drying process, and provides a more energy-saving, environmentally friendly, low-carbon sludge treatment solution. We are able to design a variety of energy utilization systems to reduce customers' energy requirements, reduce operating costs and recover investment as quickly as possible. details as follows:
● Solar greenhouse + industrial waste heat utilization sludge drying system; (waste heat includes steam, flue gas, hot water)
● Solar greenhouse + solar heat collection sludge drying system;
● Solar greenhouse + heat pump sludge drying system;
● Solar greenhouse + biomass boiler sludge drying system;
The new energy sludge drying system mainly includes solar energy greenhouses, automatic sludge feeding units, automatic paving units, automatic receiving and conveying units, intelligent heating units, exhaust gas treatment units, and automatic control units.
Mainly used in: sewage treatment plants, large-scale chemical, pharmaceutical, papermaking, textile printing and dyeing enterprises, thermal power plants, etc.
● Effective cross-utilization of solar radiation heat energy and auxiliary heat sources
By constructing a solar greenhouse with a special structure, the solar thermal energy in the daytime is fully used, and the auxiliary energy is used at night to increase the indoor temperature, promote the evaporation of water, achieve all-weather production, and greatly improve the drying efficiency. Under normal climate conditions, the indoor temperature can be maintained at 45 ~ 60ºC in summer, and 30 ~ 35ºC in winter and night. After drying, part of the sludge can be mixed with biomass raw materials to be burned to achieve the purpose of recycling.
● Mechanical cloth, flipping technology
Adopt automatic mechanical means to uniformly distribute, turn over, cut, and advance sludge under high temperature conditions to increase the surface area of sludge particles and accelerate the volatilization of water, and through intelligent control system, make it a ratio Manual flipping or natural drying is more efficient and highly mechanized / automated production process.
● Hot air convection air circulation
By directional hot air flow and intermittent air intake and exhaust systems, the orderly flow of humid air in the greenhouse is accelerated, and high-humidity air is exhausted in time to form a pressure difference between the indoor steam pressure and the steam pressure on the surface of the sludge, thereby promoting moisture evaporation. Improve the efficiency of sludge drying.
● Exhaust emission control
The exhaust gas purification system effectively avoids the dissemination of sludge odors and eliminates pollution to the ambient air.
● PLC automation control
By integrating the various parts of the sludge drying system in a highly automated PLC industrial control system, it becomes a complete sludge drying system. From the feeding to the end of drying, fully automatic production can be achieved. The actual conditions of humidity and sludge characteristics are adjusted in each segment to achieve higher sludge drying efficiency and reduce energy consumption and costs of sludge drying.
