Titanium alloy flash drying machine - Corrosion-resistant titanium material drying equipment - Jiangsu Bohong drying equipment

In the production processes of fine chemicals, pharmaceutical intermediates, new energy materials, and high-purity powders, some materials have strong corrosiveness, or there are strict control requirements for the content of iron, copper, and nickel and other metal impurities. Traditional stainless steel drying equipment may encounter corrosion, shortened equipment lifespan, and the introduction of metal impurities under certain working conditions.
To meet these special production needs, a flash drying machine made of titanium alloy is used. It provides a new equipment option for the continuous drying of corrosive materials.
Jiangsu Bohong drying equipment focuses on the research and manufacturing of special material drying equipment and has over 10 years of experience in drying equipment manufacturing. It can customize TA2 and TA10 titanium material flash drying equipment according to the corrosion characteristics of the materials, drying temperature, processing volume, and product purity requirements, providing corrosion-resistant drying solutions for the fine chemical and new material industries.
I. What is a titanium alloy flash drying machine?
The titanium alloy flash drying machine is a continuous drying equipment based on the conventional rotary flash drying equipment, with material upgrade and structure optimization for special corrosive environments and product purity requirements.
The equipment mainly consists of the feeding system, drying main body, hot air system, stirring and crushing device, cyclone separator, dust collector, and finished product collection device.
Wet materials enter the drying main body through the spiral feeder at the bottom. Under the action of the high-speed rotating stirring device, the wet materials are continuously broken and dispersed, and come into full contact with the hot air entering the main body. The moisture on the surface of the materials evaporates rapidly, and the dried powder moves upward under the action of the hot air flow, passing through the classification area and entering the cyclone separation and dust removal system, and finally completing the product collection.
Compared with ordinary static drying equipment, the rotary flash drying machine has the characteristics of continuous production, shorter drying time, strong material dispersion ability, and compact equipment structure.
For the titanium alloy flash drying machine, in addition to meeting the conventional drying process, it also needs to focus on solving issues such as the corrosion resistance of the equipment material, titanium material welding processing, the quality of the material contact surface, and the stability of the equipment during long-term operation.
II. Why choose titanium material to manufacture flash drying machines?
Titanium materials have good corrosion resistance, high specific strength, and good material stability. They are widely used in the chemical industry, marine engineering, and special equipment fields.
In the manufacturing of drying equipment, choosing titanium materials is mainly to adapt to specific corrosive environments and product purity requirements.
1. Improve equipment corrosion resistance
Some fine chemical materials may be accompanied by acidic, alkaline, or salt-containing media during the drying process, causing corrosion to the inner wall of the equipment, stirring components, and conveying pipelines. Selecting suitable titanium materials based on the composition of the medium and operating conditions can improve the corrosion resistance of the equipment and reduce equipment wear caused by corrosion.
2. Reduce the risk of metal impurities introduction
In the production of new energy materials, electronic chemicals, and high-purity powders, the control of iron, copper, and nickel elements is relatively strict. Using titanium materials to manufacture material contact components helps reduce the risk of impurity contamination caused by corrosion or wear of ordinary metal materials.
3. Meet the requirements of continuous production in special processes
For production processes that require continuous feeding, continuous drying, and continuous discharge, the flash drying machine can combine the dispersion, drying, and gas-solid separation of materials, reducing intermediate transfer links and improving the automation level of the production line.
4. Extend the service life of the equipment under special working conditions
The material and equipment medium are matched, which can reduce the risk of corrosion caused by maintenance, replacement, and downtime. However, the actual service life still depends on factors such as medium concentration, temperature, flow rate, impurities, and equipment structure.
III. Core structural design of the titanium alloy flash drying machine
The titanium alloy flash drying equipment is not simply replacing the ordinary stainless steel equipment with titanium materials. The processing, welding and structural design of titanium materials have their own characteristics, and need to be considered as a whole in combination with the operating conditions of the equipment.
1. Titanium material drying machine
The drying machine is the core component of the equipment, mainly completing the crushing, dispersion and rapid drying of wet materials. According to the corrosion characteristics of the materials, titanium materials such as TA2 can be used to manufacture the material contact cylinder and related internal structures.
The internal structure of the machine needs to be reasonably designed for the heat air distribution structure, the stirring area and the classification space, to avoid the accumulation of wet materials at the bottom, and at the same time ensure that the powder after drying can be smoothly transported.
2. Titanium material stirring and crushing device
For filter cake-like, paste-like and easily agglomerated wet materials, the structure of the stirring teeth, the rotor form and the crushing gap need to be considered as priorities.
The stirring device, through high-speed rotation, continuously exposes the wet materials to mechanical shearing and collision, gradually dispersing them into smaller particles, increasing the contact area between the materials and the hot air.
For abrasive materials, the wear problem of the titanium material stirring components also needs to be considered, and structural optimization or selection of other suitable contact materials may be necessary.
3. Titanium material hot air contact system
According to the drying temperature of the materials and the requirements for heat sensitivity, the hot air system, air inlet temperature control and air volume adjustment devices should be reasonably configured.
For drying processes involving corrosive gases or volatile solvents, the materials and safety design of the hot air pipes, exhaust pipes and subsequent processing equipment need to be carried out accordingly.
4. Cyclone separation and dust removal system
The dried materials enter the cyclone separator with the airflow, completing the collection of most of the powder, and the fine powder is captured by the subsequent dust removal system.
If the production process requires high control of metal impurities, the titanium material design can be adopted for the cyclone separator, the material conveying pipeline, the receiving device and other components in contact with the materials.
5. Sealing and automatic control system
According to the production environment requirements, a sealing feeding device, negative pressure operation, temperature monitoring, pressure monitoring, variable frequency speed regulation and interlock control system can be configured.
For flammable and explosive or materials containing organic solvents, corresponding explosion-proof, electrical and exhaust treatment designs are required, and the use of titanium materials alone cannot meet the safety requirements.
Four. Which materials and industries require the use of titanium flash drying machines?
Titanium alloy flash drying machines are mainly suitable for production scenarios where there are special requirements for the corrosion resistance of the equipment, the purity of the product and the continuous drying capacity.
Fine chemical industry
Some organic acid salts, inorganic salts, chemical intermediates and special corrosive filter cakes have higher requirements for the material of the equipment during the drying process. Using titanium material contact components can improve the corrosion resistance of the equipment according to specific medium conditions.
New energy materials industry
Some new energy materials and high-purity powders require the control of metal elements such as iron, copper and nickel during the production process. Titanium equipment can be one of the equipment solutions to reduce the risk of metal pollution.
Pharmaceutical intermediate industry
Some pharmaceutical intermediates have corrosive, heat-sensitive or high-purity requirements, and need to select an appropriate drying method according to the material properties. For wet filter cakes and wet powders suitable for flash drying, titanium flash drying equipment can be used for continuous processing.
Fluorine chemical and inorganic chemical industry
Some fluorine-containing chemical intermediates, special inorganic salts and corrosive chemical materials require special equipment material assessment. It should be particularly noted that the presence of fluorine does not necessarily mean that titanium materials are suitable, and the corrosion test and material selection must be combined with the fluorine ion concentration, acidity, temperature and material form.
Five. What are the differences between titanium flash drying machines and ordinary stainless steel flash drying machines?
Comparison items Ordinary stainless steel flash drying machine Titanium flash drying machine
Main material 304, 316L, etc. TA2, TA10, etc.
Corrosion resistance Depends on the medium and grade Has better corrosion resistance for the applicable medium
Product purity control Assess the risk of metal contact Help reduce the risk of introducing some metal impurities
Equipment manufacturing Conventional stainless steel processing technology Requires specialized titanium material processing and welding techniques
Application scenarios General chemical, food and powder manufacturing Special corrosive conditions and high-purity production
The titanium flash dryer is not superior to stainless steel equipment for all materials. For ordinary non-corrosive materials, 316L stainless steel may have better economic benefits. Only when there are clear requirements for corrosion resistance, metal impurity control and equipment service life, it is necessary to consider the titanium material solution.
