after coal slime drying, the drying degree required by different users is different, which is mainly e to different uses
thermal power plants: thermal power plants are still the mainstream of power supply in China. Although wind power generation and nuclear power are new energy power supply, the power supply in China is mainly thermal power generation, so the use of coal is still very large. In order to save energy consumption, many coal washing plants have to pay more attention to energy consumption, After the slime formed by coal washing is dried by the slime dryer, the moisture content of the slime is below ten points, which can be used as coal for thermal power generation
clean coal: clean coal has a very high calorific value, which is high energy coal. Some
users need to use slime dryer for drying, and the dried slime is used as clean coal
for smelting: compared with clean coal, the requirements for smelting coal are not so high, similar to those for thermal power plants, and the requirements for water content are not so high.
in fact, you can go to Henan Ruiao to have a look, and they can also take materials for investigation
Slime is a kind of slime like material with poor fluidity. It's better to use a single cylinder when drying. The internal space is large and there is no turning point. Materials can be dried smoothly.
there are many brands of slime dryers. Gongyi Jinhua has been making slime dryers for a long time and has very good technology in the field of dryers. There are many proction sites
in terms of price, it mainly depends on the size of equipment output. Generally, the price of one equipment can be calculated only by reporting the size of one equipment according to the output, and then matching with coal injection machine, combustion chamber, st collector, fan, conveyor belt, feeder and other equipment
mining instry, is difficult to realize instrial application e to many unfavorable conditions such as high moisture, high viscosity, high water holding capacity and low calorific value, which has been rejected by power users for a long time, and the main outlet is civil land sales. Since the reform and opening up, the national economy has developed rapidly, the coal output has leaped to the first place in the world, and the market situation has changed greatly. The depth and breadth of coal processing are developing rapidly, and the output of slime has increased significantly. How to improve the added value of slime and the comprehensive utilization of slime has become an urgent problem. The slime drying instry has also developed rapidly. Investment in slime drying instry not only has huge economic benefits but also good social benefits. It not only protects the environment and obtains economic benefits, but also responds to the national energy conservation and emission rection policy. Under the influence of the current global financial crisis, the downturn of various instries, investment in slime drying instry is your new choice for steady investment. Slime is a kind of lump material with high moisture content, high viscosity and easy to be agglomerated, which is formed by precipitation after washing and stacking in the open air ring coal mining. The traditional dryer does not aim at the characteristics of slime, so it is difficult to dry, difficult to control, and easy to catch fire. The finished proct is uneven dry and wet or the skin is dry and wet, and the drying cost is high, It is not suitable for drying slime< Structure, working principle and performance characteristics of slime drying equipment:
structure of slime drying equipment: mainly composed of heat source, dispersing device, belt feeder, feeder, rotary drum, transmission parts, belt discharger, inced draft fan, discharger and power distribution cabinet
the working principle of the slime dryer is as follows: the slime itself has high humidity and high cohesiveness. In the drying process, the wet slime enters the slime dispersing equipment through the belt conveyor, and the rapidly dispersed lump slime enters the negative pressure dryer, which is divided into the following working areas: first, the material guiding area, When the wet coal slime comes into contact with the high temperature and negative pressure hot air, a large amount of water is evaporated rapidly, and the coal slime is led into the next working area if it does not form a bond under the large guide angle of the plate; The second is the cleaning area, where the wet coal slime is lifted up by the board to form a curtain state, and the phenomenon of sticking to the drum wall is easy to form when the material falls down. Because the cleaning device is designed in this area, the cleaning device can quickly clean up the slime sticking to the drum wall. In this process, the cleaning device also plays a role in crushing the agglomerate of the material, thus increasing the heat exchange area, The efficiency of heat and mass transfer is improved and the drying rate is increased; The third is the inclined lifting plate area, which is a low-temperature drying area. The slime in this area has been in a low moisture loose state, and there is no bonding phenomenon in this area. After heat exchange, the finished proct reaches the required moisture requirements and moves into the final discharge area; The fourth is the discharge area, where the dryer drum is not equipped with a plate, and the materials roll and slide to the discharge port to complete the whole drying process
performance characteristics of slime dryer:
1. The operating parameters can be changed according to the properties of different materials, so that the materials can form a stable full broken fabric curtain in the dryer barrel, and the mass and heat exchange is more sufficient
2. The dryer has strong overload resistance, large capacity, low fuel consumption and low drying cost
3. The new feeding and discharging device eliminates the feeding blockage, discontinuity, nonuniformity and return of the drum dryer, and reces the load of the st removal system
4. By adopting the downstream drying method, the flue gas and wet materials enter the dryer from the same side, which can make use of the high-temperature flue gas to obtain high evaporation intensity, low outlet temperature and high thermal efficiency
5. The new internal structure strengthens the cleaning and heat conction of the dispersed materials, eliminates the sticking phenomenon on the inner wall of the cylinder, and has stronger adaptability to the moisture and viscosity of the materials
6. The particle size and moisture content of the proct can be controlled according to the user's requirements. When drying the slime, the moisture content of the proct can reach below 8%, and the particle size can be controlled below 8 mm
7. The dryer adopts "self-aligning supporting roller device", which makes the supporting roller and rolling ring always in linear contact, thus greatly recing the wear and power loss
8. The dryer realizes "zero horizontal thrust", greatly reces the wear of the retaining roller, and the cylinder runs smoothly and reliably
the slime dryer developed by our company can also be used in building materials, metallurgy, chemical instry and cement instry to dry slag, limestone, pulverized coal, slag, clay and other materials. The utility model has the advantages of reasonable structure, excellent proction, high efficiency, energy saving, convenient operation, etc. Our company's procts guarantee quality, reputation first, free installation and debugging, consignment can be compared with other factories in quality, service and price.
working principle of the dryer:
the heat source of the dryer comes from the combustion device, and the slime dryer (drying equipment) adopts the downstream heating mode. Therefore, the materials that need to be dried will slide into the cylinder from the feed box and feed box, that is, they will be pushed back by the spiral plate. Due to the inclined placement of the dryer equipment, on the one hand, the material flows to the rear end under the action of gravity and rotation, on the other hand, the material is repeatedly picked up by the plate, carried to the upper end, and then continuously spread down, so that the material forms a uniform curtain in the cylinder and fully exchanges with the hot air flow in the cylinder. Due to the repeated spreading of the material, the moisture content is graally dried, So as to achieve the purpose of drying equipment drying.
