Special airflowers for wood chips

 

project description:

With the development of science and technology and the tension of resources, sawdust (sawdust), and various straws, edible fungi slag has become a resource available from discarded waste for use in making wood chips and making high combustion values Of the bio-fuels, which require wood chips and broken debris to go through the drying process. And many of the drying equipment on the market does not apply, a lot of biomass pellet fuel manufacturers precisely because the drying equipment is inefficient, equipment operation is not smooth and product quality and other issues, can only maintain production, low profits, so that biomass fuels, charcoal Production enterprises are forced to seek the production of equipment, high efficiency, advanced technology equipment manufacturing enterprises. The optimal design of the drying equipment must first meet the requirements of producing quality and competitive products, followed by investment in the province, the smooth operation of machinery and equipment and low maintenance costs, high labor productivity, and taking into account the working conditions and environmental requirements.

 

First, the equipment overview:

Sawdust (sawdust) is a water content of about 40-50% of the organic matter, requiring a general water content of about 12% after drying, the main water is free water and biological water, free water is easier to remove, and biological Water is difficult to remove. Sawdust (sawdust) drying process is mainly from the production size, finished product characteristics, ease of operation or not, one-time investment and operating costs and other considerations. At present, most of the wood drying equipment using air dryer, fluidized bed dryer and drum dryer, air dryer and drum dryer in the most widely used in wood drying, air dryer The most provinces, especially in the production of small, but because the air dryer drying time is very short, and the thickness can not be graded, prone to dry out of the water instability, and prone to block, run unreliable, resulting in the rear equipment Can not match, resulting in investment and energy waste.

 

Second, the device description:

The new energy-saving wood chip dryer used in the dry design and production of the United States is a kind of drying equipment, which is designed according to the specific characteristics of the sawdust, and analyzes the influence of the structure of the dryer on the yield and quality of the sawdust made.

According to the characteristics of the wood material, how to improve the material filling rate and material retention time in the cylinder and other issues on the dryer was a comprehensive technical transformation, the use of new modular Yang device, multi-layer sleeve structure, so that material without wind tunnel Phenomenon, so that the wood can be fully heat transfer, dehydration; and increase the coarse particle separation device, greatly improving the heat utilization rate, but also improve the production; in the same investment conditions, the health of the production of dryer advantage is very obvious.

 

Third, the equipment features:

Wood chip drying equipment Main features:

1. Automatic control, can ensure that dry wood moisture dry and stable.

2. Automatic to stone, in addition to iron, can ensure that the baking wood impurities do not enter the post-process.

3. Equipment required investment is foreign imports of 1/6.

4. Self-insulation thermal efficiency of the cylinder up to 70% or more (traditional single-cylinder dryer thermal efficiency of only 35%), improve thermal efficiency of more than 50%.

5. The use of tail drive, transmission more stable and reliable; completely change the wheel rotation often slip affect the production phenomenon.

6. Reduce the area by about 50% than the single-cylinder dryer, civil construction investment by about 50%, power consumption by 60%.

7. A variety of weekly hairpin combination distribution, effective control of drying time. Drying effect is good.

8. Can be easily adjusted according to user requirements to the final indicators of moisture.

9. The use of frequency control speed control material flow, according to user needs to easily control the final moisture index.

10. Low outlet temperature, dust removal equipment for a long time, continuous production for the next process.

11. Supporting a new type of energy-saving hot stove, energy efficient, thermal control, simple operation, coal consumption down as high as 60%.
