Product introduction:

Peat, also known as grass peat, peat soil, black soil, peat, it is all coal with the lowest degree of coalification, also the most primitive state of coal. Peat is formed in peat swamps, and than formed by the pressure of overlying sediments and further Under bacteriolysis conditions, the compaction and dehydration become more firm. Formed coal is sterile, non-toxic, non-polluting, good ventilation performance, light weight, water retention, fertilizer retention, beneficial to microbial activity, enhanced biological performance, abundant nutrition. It is not only a cultivation matrix but also a good soil conditioner and contains high organic matter, humic acid and nutrients. The organic matter in peat is mainly composed of cellulose, hemicellulose, lignin, humic acid, and asphalt materials. Peat has a wide range of uses, it can be used in agriculture, such as soil-based cultivation of organic fertilizers and seedlings and flower cultivation, and in industries such as power generation fuels and chemical raw materials. Because peat is composed of various organic compounds, protein feeds, biological growth agents and phytostimulating hormones. All above mentioned can be extracted from peat, and different types of adsorbents and pharmaceutical preparations can also be produced.

Product working principle:

The flowchart of material: Moisture content is about 50-65% and peat is fed by a screw conveyor into a rotary drum dryer to achieve downstream drying. The materials are continuously picked up and scattered under the copying board, and the materials are scattered and spirally advanced. The inner of dryer has stirring blade device will make the material fully stirred, break up and beat, and the material and the hot gas are fully in heat exchange. The moisture quickly evaporates and vaporizes. The material that achieves the drying effect quickly moves out of the drum under the action of hot air. The wet material that does not reach the drying effect that cannot travel fast due to its own weight, and the material inside of the drum is fully dried to achieve a drying effect, and the drying process is completed and discharged from the screw conveyor. Inside the drum has a shock cleaning device to prevent material sticking to the wall.
The flowchart of gas: the air is heated by the hot air furnace of draught fan and enter the hot air furnace to burn and get heated, the temperature reaches 600-850°C. After the dryer, the induced draft fan draws the material in the dryer to dry, evaporate water, pass the three-layer heat exchange, and the wind temperature reduced to 55-60°C and discharged from the dryer. The dust containing wet dust passes the cyclone dust collector and the wet dust collector 6gets to the emission standards.

Product Features:

1. It can realize intelligent control, one-button operation, automatic control of operating parameters, the dryer always running in the best status, to ensure that the drying out of the material moisture is uniform and stable.
2. The built-in stirring paddle device stirs and crushes the material completely. The heat exchange between the material and the hot gas material is sufficient. The unit production capacity of the equipment increased more than 50%, and the energy consumption of the fuel reduced more than 30%.
3. With four-wheel drive, the transmission is more stable, safe and reliable.
4. Comparing with the drum dryer, it reduced the floor area by about 40%, civil engineering investment decreased by about 40%, equipment investment decreased by 20%.
5. The internal structure of the dryer adopted a variety of high-efficiency combination modes of lift plate to effectively regulate the drying process and heat distribution, and the heat utilization rate is high. The discharge temperature of exhaust gas is lower than 50°C.
6. The use of frequency conversion to regulate the flow parameters such as material flow, hot air supply and drum rotation speed can easily control the final moisture index and equipment productivity according to the needs of users.
7. Modular dust collection, dust purification heat recovery configuration, safety and environmental protection
8. Supporting a variety of energy-saving new hot air furnace, high-efficiency, energy-saving, controllable heating, simple operation, energy consumption reduced by 30%, power consumption reduced by 20%, and operating costs get lower.
