Key words: dyestuff waste water drier, printing and dyeing wastewater, waste liquid drying equipment, printing and dyeing wastewater, waste liquid dryer, printing and dyeing wastewater dedicated spray dryer, waste water drier, dyeing wastewater drying
Classification: waste water treatment engineering
Case overview: Haomai drying dye wastewater dryer, printing and dyeing wastewater waste liquid drying equipment, wide applicability, fast drying rate. The new type of printing and dyeing wastewater spray dryer has large capacity, small footprint, small investment and advanced technology. Welcome to inquire!
With the development of printing and dyeing industry, hundreds of thousands of tons of dyes are used in textile and papermaking industries in China every year, resulting in a large number of dye wastewater, which is recognized as one of the refractory industrial wastewater at home and abroad. Printing and dyeing wastewater has the characteristics of large amount of water, high content of organic poisons, complex components and difficult degradation. Especially, even if the concentration of residual dye components in the wastewater is very low, it will reduce the light transmittance of water body and damage the water system. Over the years, our company has been following the call of the state to manufacture energy saving and environmental protection equipment. Now, we are introducing new printing and dyeing wastewater spray drying machine. The equipment processing capacity, small footprint, small investment, advanced technology, welcome to inquire!
The dyestuff wastewater dryer and printing and dyeing wastewater waste liquid drying equipment introduced by Changzhou Haomai drying Co., Ltd. have wide applicability and fast drying rate. 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.
Introduction of dye wastewater 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 dye wastewater dryer
After filtration and heating, the air enters the air distributor at the top of the dryer, and the hot air enters the drying chamber evenly in a spiral shape. The high speed centrifugal atomizer at the top of the tower (swivel) is atomized into tiny droplets of mist, contacting with the hot air and flowing into the finished product in a very short time. The finished product is continuously output from the bottom of drying tower and cyclone separator, and the waste gas is drained by fan.
Performance characteristics of dye wastewater dryer
The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% - 98% of the water can be evaporated instantly, and the drying time is only a few seconds. It is especially suitable for the drying of heat sensitive materials.
The product has good uniformity, fluidity and solubility, high purity and good quality.
The production process is simplified and the operation control is convenient. The liquid with moisture content of 40-60% (up to 90% of special materials) can be dried into powder products at one time. After drying, there is no need to crush and screen, which reduces the production process and improves the product purity. The particle size, bulk density and moisture of the product can be adjusted by changing the operating conditions within a certain range, which is very convenient for control and management.
Maintenance of atomizer of dye wastewater dryer:
1. This type of centrifugal spray dryer needs sufficient distilled water before the water starts. Check whether the diaphragm at the bottom of the medicine cup is leaking, so as to prevent the liquid medicine from entering the water and causing waste. In addition, the liquid crystal tablet of the medicine is also provided. The amount of fog should be adjusted from small to large, and the timer should be turned clockwise and turned anticlockwise.
2. Advocate the use of the mask to make the atomization, do not bite the mouth (to prevent the flow into the spray dryer atomizer, rust spray dryer internal components of atomizer). At the end of each use, the water in the water tank is completely drained, and the atomizer of the dryer is dried. The wafer is dried with a soft cloth. If there is scale on the chip, soak it in a special cleaning solution for 3 to 5 minutes, and then dry it to prolong its service life.
3. In order to prolong the service life, it is suggested that two atomizers should be used alternately in actual operation. Generally, the atomizer needs to remove the atomizer disk, material liquid distribution plate, guide shaft and other parts to clean. If the guide bearing is slightly scratched, it can be polished with fine abrasive cloth. If there is serious scratch, replace the bearing. When the continuous service time is longer, the water tank can be used for cooling to extend the service life properly.
4. The atomizer of LPG high speed centrifugal spray dryer can be added to the material after normal operation. Avoid adding nebulizer or atomizer before feeding, and add material before reaching the rated value, so as not to cause the atomization effect is not ideal and the atomizer overload.
The dyestuff waste water dryer and printing and dyeing wastewater waste liquid drying equipment introduced by Changzhou Haomai drying Co., Ltd. have wide applicability, fast drying rate, large treatment capacity, small investment and advanced technology. Welcome new and old customers to come to consult and purchase!
