Special airflow dryer for wood sawdust and straw
Nav：Agroforestry
Content：The drying equipment of wood chip mostly adopts the air dryer, the fluidized bed dryer and the rotary dryer, in which the air dryer and the drum dryer are most widely used in the drying of wood chips.
Project Description:
With the development of science and technology and the shortage of resources, wood chips (sawdust), and all kinds of straw and mushroom residue have been turned from abandoned waste to available resources, used as wood chips and high burning value biofuels, all of which require wood and broken residue to pass the drying process. A lot of drying equipment in the market is not applicable. Many biomass pellet fuel manufacturers can only maintain production and have low profits due to low efficiency of drying equipment, poor operation of equipment and quality of products. Therefore, biomass fuel and charcoal production enterprises are forced to seek high efficiency in production equipment. Enter the equipment professional manufacturing enterprise. The optimization design of the drying equipment should first meet the products that can produce the competitive quality, then the investment province, the smooth operation of the machinery and equipment, the low maintenance cost, the high labor productivity, and the consideration of the labor conditions and environmental protection requirements.
一、 Equipment Overview:
Wood sawdust (sawdust) is a kind of organic matter with water content of about 40-50%. The water content is about 12% after drying. The main moisture is free water and biological water. Free water is easily removed, while biological water is difficult to remove. The drying process of sawdust (sawdust) is mainly considered from the aspects of the size of the output, the properties of the finished products, the convenience of operation, the one-time investment and the operating cost. At present, most of the wood drying equipment adopts air dryers, fluidized bed dryers and rotary dryers. The air dryers and drum dryers are most widely used in the drying of wood chips. The investment of the air dryers is the most economical, especially in the production hours, but the drying time of the air dryer is very short, and the thickness can not be graded. It is easy to appear drying out of water instability, and easy to block, operation is not reliable, resulting in the back of the equipment can not be matched, resulting in the waste of investment and energy.
二、 Equipment Description:
The new energy-saving wood sawdust drier designed and produced by our company is a kind of drying equipment with large amount of treatment. It is designed and manufactured according to the specific characteristics of wood chips, and analyzes the influence of the structure of the dryer on the output and quality of the wood chips.
According to the characteristics of sawdust material, the drying machine is completely reformed on how to improve the filling rate of material and the residence time of the material in the barrel. A new type of combined type lifting device and multi-layer sleeve structure are used to make the material without wind tunnel, so that the wood chips can be fully heat and dehydrated, and the coarse and fine particles are added. Separation device, greatly improve the heat utilization rate, but also improve the output; under the same investment conditions, our company's production of dryer advantage is very obvious.
三、 Equipment features:
The main characteristics of wood chip drying equipment:
1. automatic control can ensure the moisture content of dried sawdust is uniform and stable.
2. automatic stone removal and iron removal can ensure that the impurities in the wood chips do not enter the back process.
The investment required for 3. equipment is 1/6 of foreign imported products.
4. cylinder self insulation thermal efficiency of up to 70% (traditional single dryer dryer thermal efficiency is only 35%), improve the thermal efficiency of more than 50%.
5. use the rear drive, the transmission is more stable and reliable; changing the supporting wheel rotation frequently, skidding affects the production phenomenon.
6., compared with the single cylinder dryer, it reduces the occupation area by 50%, and the civil construction investment is reduced by about 50%, and the electricity consumption is reduced by 60%.
More than 7. kinds of weekly feed combinations are available to control drying time effectively. The drying effect is good.
8., we can easily control the final water requirement according to the user's requirements.
9. frequency control is used to control material flow, and the final moisture requirement can be easily adjusted according to users' needs.
10. the outlet temperature is low and the dust removal equipment is used for a long time.
11. a new type of energy-saving hot blast stove is set up, which is efficient, energy saving, controllable in thermal engineering and simple in operation, and the coal consumption is reduced by about 60%.
