Description
Key words: chrome green dryer, chrome green flash dryer, chrome green flash dryer
Classification: chemical engineering industry
Case overview: chrome green flash dryer is a new type of continuous drying equipment integrating drying, crushing and screening. It is especially suitable for drying filter cake, paste and slurry materials. The drying time of wet materials in the drying tower is only 5-8 seconds, and the moisture evaporates instantaneously. The quality of the dried products is closely related to the drying temperature, wind speed, air volume and crushing speed
Chrome green, chromium trioxide, light green crystal. 21 g / cm3. Melting point (2266 ± 25 ℃). The boiling point is 4000 ℃. It is soluble in hot alkali metal bromate solution. It is insoluble in water, alcohol, acid and alkali. It is very stable to light, atmosphere, high temperature and corrosive gases such as sulfur dioxide and hydrogen sulfide. It has high hiding power and is poisonous.
The preparation method of chrome green is as follows
1. It is made of potassium dichromate and sulfur by reduction reaction, wet grinding, hot water washing, pressure filtration, drying and crushing.
2. It is prepared by thermal decomposition of chromium hydroxide at high temperature, washing, drying and crushing.
Chrome green uses:
1. It is used for coloring enamel and glass industry, especially for the production of ceramic pigment with bright and bright color.
2. Used for temperature resistant coatings, fluorocarbon coatings, outdoor high weather resistant coatings; outdoor plastic products, plastic steel door and window profiles, color masterbatch, etc.
3. It is mainly used for making light resistant coatings, grinding materials, green polishing paste and special ink for printing banknotes.
Chrome green special dryer:
Chrome green flash dryer is a new type of continuous drying equipment which integrates drying, crushing and screening. It is especially suitable for drying filter cake, paste and slurry materials. The drying time of wet materials in the drying tower is only 5-8 seconds, and the moisture evaporates instantaneously. The quality of the dried products has a great relationship with the drying temperature, wind speed, air volume and crushing speed. Haomai drying has innovative design scheme, which can adjust the wind speed of flash drying tangent line, and adjust the size of finished product particles and final water content.
Working principle of rotary flash dryer for chrome green
The natural air is used for drying. After passing through the air filter, the natural wind is blown into the air heating equipment by the fan and heated. The heated hot air is then distributed into a uniform cyclone with a certain flow rate and flow direction through the hot air distributor of the flash evaporation host. The cyclone contacts and collides with the wet material added by the spiral feeder, and begins a series of physical changes, such as mass and heat exchange and separation, so that the material is separated from the moisture content, and finally reaches drying.
Performance characteristics of rotary flash dryer for chrome green
1. The organic combination of swirl, fluidization, spouting and comminution classification technology.
2. Compact equipment, small size, high production efficiency, continuous production, realized
3. Small equipment, large production ".
4. High drying strength, low energy consumption and high thermal efficiency.
5. Short residence time of materials and good quality of finished products can be used for drying heat sensitive materials.
6. Negative pressure or micro negative pressure operation, good airtightness, high efficiency and elimination of environmental pollution.
