With the sustained and rapid development of China's economy, the continuous increase of urban process and industrialization process, environmental pollution is increasingly serious, and the state attaches more and more importance to environmental protection. Over the years, our company has been following the call of the state, committed to manufacturing energy-saving and environmental protection equipment. In this extraordinary period, our company launched a new type of special dryer for waste water and waste liquid, which is used to treat waste water and waste liquid of various industries, so as to help enterprises develop rapidly.
Waste water includes domestic sewage, industrial wastewater and other useless water flowing into drainage pipes and canals due to the initial rainfall runoff. Generally, it refers to the water that can not be recycled after certain technical treatment or the water with grade I pollution is difficult to be purified and treated. The industrial wastewater also includes electrolytic salt industrial wastewater, heavy metal smelting industrial wastewater, electroplating industrial wastewater, petroleum refining industrial wastewater, pesticide manufacturing industrial wastewater, etc.; these wastewater often contain a variety of toxic substances and ultra-high pH, so in the drying treatment, the material and process requirements of drying equipment are higher.
Changzhou Haomai drying launched a special dryer for waste water and waste liquid and industrial waste water drying equipment. There are many kinds of spray drying principle, but they can be roughly divided into three categories (1, centrifugal spray drying 2, pressure spray drying 3, pneumatic spray drying, 4, pneumatic pressure mixing spray), but no matter that spray can be divided into counterflow discharging and downstream discharging. The materials for countercurrent discharge are inorganic materials that can withstand high temperature, such as naphthalene water reducer, inorganic dispersant, detergent, calcium phosphate, ferric sulfate, flocculant, ceramic powder, etc. The material of forward flow discharging is just opposite to the above, which can only withstand low temperature (organic), such as egg white, egg yolk, plant extract, animal blood, extract, microbial protein, etc.
Brief introduction of waste water dryer
Spray drying is a widely applied technology in liquid forming and drying industry. ^ it is suitable for producing powdery and granular solid products from solution, emulsion, suspension and paste liquid raw materials. Therefore, spray drying is an ideal process when the particle size distribution, residual water content, bulk density and particle shape of finished products must conform to the ^ standard.
Working principle of industrial wastewater dryer
The air enters the air distributor at the top of the centrifugal spray dryer through filters and heaters, and the hot air spirals evenly into the dryer. The feed liquid is pumped to the centrifugal atomizer on the top of the dryer by the feed tank through the filter, so that the feed liquid is sprayed into tiny mist droplets. The feed liquid and hot air flow together, and the water evaporates rapidly. The finished product is discharged by the bottom of the drying tower and the cyclone separator, and the waste gas is discharged by the fan.

According to the actual situation, users can choose the heating mode, dust collection and dust removal mode.
Introduction to operation of waste water dryer
After the normal operation of the centrifugal spray dryer, it should also regularly collect and check the operation of each system regularly, and record the technological parameters. At the end of the operation, the heating device should be shut down first, and water should be used to replace the feed liquid to flush the residual liquid in the material pipe, and then the feed pump should be shut down. When the inlet temperature is lower than 100 ℃, the forced draft fan and exhaust fan can be stopped. Then clean up the residual materials in the drying tower and dust remover, turn off the dust remover and air hammer, and then turn off the main power supply to complete the production operation. In case of emergency, the equipment must be shut down immediately, and the forced draft fan and feed pump shall be shut down first. In case of sudden power failure, the tower body shall be cooled naturally, and then the blowdown valve shall be opened to drain the slurry in the slurry pipeline and the equipment shall be cleaned.
In addition, the spray dryer should be removed after the use of the spray tray and immersed in water to clean the residual substances. When you can't wash it off with water, you should brush it with a brush. Because the residual material on the spray tray will bring the spray imbalance, which will seriously affect the service life of the sprinkler and even damage other parts. Do not lay the nozzle horizontally after the operation and during transportation. If the installation is not correct, the spindle will be bent and the use will be affected.
Characteristics of special dryer for waste water and waste liquid
The results show that the drying speed is fast, the surface area of the material liquid is greatly increased after atomization, and 95% - 98% of the moisture can be evaporated instantly in the hot air flow. The drying time is only 5-15 seconds, which has the characteristics of instantaneous drying.
A special air dryer is provided to reduce the resistance of the air dryer.
3. The production process is simplified and suitable for continuous control production. The liquid with moisture content of 40-90% can be dried into powder at one time, so as to reduce crushing and screening and improve product purity.
The drying process of materials is completed in a short time. It is suitable for drying heat sensitive materials and can keep the color, aroma and taste of materials.
The product has good dispersibility, fluidity and solubility, and its particle size, looseness and moisture can be adjusted within a certain range.
Changzhou Hao Mei drying Engineering Co., Ltd. sells excellent quality, high efficiency, low energy consumption, centrifugal spray dryer, pressure sprayer granulator, air spray dryer, air pressure combined spray dryer.
