Case summary: naphthalene superplasticizer is an important additive in cement. The final moisture content of the finished product must be 0.5%, and the finished product can not be hygroscopic. During the drying process, the control parameters are required to be high. According to the characteristics of materials and the rich production experience of many years, our company has been designed by professional designers, and has successfully produced several sets of advanced technology of naphthalene series water reducing agent spray dryer.
summary: with the development of China's construction, the requirements for building concrete admixtures are higher and higher. High efficiency naphthalene series water reducer is an important additive in cement. The final moisture content of the finished product must be 0.5%, and the finished product can not be hygroscopic. According to the characteristics of materials and the rich production experience of many years, our company has been designed by professional designers, and has successfully produced several sets of advanced technology of naphthalene series water reducing agent spray drying machine, which has been praised by many users for its superior performance and good service.
Engineering principle:The special spray drying machine for water reducing agent is heated by the high temperature hot air generated by the hot blast stove, and enters the spiral channel of the top part of the drying chamber. Under the action of the hot air distributor, the uniform rotating air flow enters the drying chamber quickly and keeps the wind evenly distributed in the tower. Water reducing agent and other liquid materials pass through the high-speed rotating atomizer to produce dispersed fine material mist. The material mist contacts with the swirling hot air, and the water evaporates rapidly. In a very short time, the material can be dried to obtain hollow and thin spherical products, which can be rapidly dissolved in water.
Equipment features:
1. The equipment has flexible heat source configuration, high inlet air temperature and high drying efficiency
the heat source can be oil, coal, natural gas hot blast stove or high temperature waste heat supply. The output temperature is above 280 ℃, which can effectively improve the drying efficiency.
2. The drying process is stable and the degree of automation control is high
The system loop uses advanced fuzzy control mode, and the corresponding program can be set according to the relevant data, so as to automatically track and control the relevant parameters such as the inlet air temperature, the outlet air temperature, the conveying speed, the operating pressure and so on. The temperature can be controlled within ± 5 ℃ to achieve the purpose of automatic stable control.
3. High powder collection rate, reducing material loss
this machine adopts two-stage high-efficiency cyclone separator, and selects two-stage cyclone combination according to the characteristics of materials, so that the powder collection rate is as high as 99.5%. A variety of waste gas will be generated in the production process of naphthalene series water reducer. With the increase of foam dust removal system, the treatment effect of waste gas pollutants can reach more than 98%, which ensures the compliance with environmental protection requirements.
The unique design of centrifugal spray drying system for naphthalene superplasticizer:
Hot air distribution treatment:
1. The hot air volute adopts accelerated constant cross-section logarithmic spiral structure, which makes the inlet air more uniform and stable;
2. The hot air distributor adopts double sided adjustable structure;
3. The internal air guide mechanism has a certain angle (adjustable angle) to increase the rotation of hot air, enhance the shear force of hot air on the material film after atomization of atomizer, and promote the heat and mass exchange process between hot air and materials;
4. The external wind guide mechanism is generally fixed angle, its main function is to suppress the turbulent area formed between the atomization disk and the internal air guide mechanism, so as to ensure that the materials do not overturn;
5. When the atomizer seat sinks, the distance between the atomizer tray and the tower top is increased, and the peripheral wind guide cover is added to avoid the material overturning phenomenon twice.
Core components centrifugal atomizer treatment:
1. The products of domestic high-quality atomizer manufacturers are adopted, and the air sealing device is specially required. The compressed air is pressurized and sealed through three labyrinth air channels to ensure no oil leakage;
2. The combined cooling system of water cooling and air cooling is adopted to eliminate the thermal expansion caused by the heat absorbed in the process of mechanical transmission and drying of atomizer, so as to reduce the failure rate of equipment;
3. The oil circuit safety protection system is adopted to conduct real-time digital detection on the oil pressure, oil temperature and other data during the operation of the atomizer. In case of oil shortage or oil circuit failure, the protection system will start automatically and disconnect the main motor to protect the safety of the atomizer and ensure its service life.
