Case overview: Changzhou Haomai drying Engineering Co., Ltd. combines the national conditions and policies of China's energy conservation, environmental protection and sustainable development, develops a new type of clean special belt dryer for coal balls, which opens a way for efficient utilization of coal slime.
Application: briquette dryer clean briquette drying
Application of clean briquette dryer
With the depletion of oil and the development of science and technology, coal, as the main energy and important industrial raw materials in China, will become one of the irreplaceable energy in human production and life.
Because of the high moisture content of coal slime, it is very difficult to reuse it. The previous air drying and vertical dryer have been difficult to meet the production demand of briquette. With the increasing demand of saving and environmental protection briquette, Changzhou Haomai drying Engineering Co., Ltd. combines the national conditions and policies of energy conservation and environmental protection sustainable development in China, and develops a new type of clean special belt dryer for coal briquette Mud has opened up a way of efficient utilization. The clean coal ball dryer can effectively recover the coal slime doped with water and conduct comprehensive drying treatment. The quality of the coal slime after drying treatment is improved. It can be used as the additive of brick factory or cement raw material and put into the corresponding field. It not only alleviates the decreasing coal resources in our country to a certain extent, but also reduces the environmental pollution in the mining area. It can also bring huge economic benefits and good social benefits.
Briquette dryer: a kind of mesh belt drying equipment, which is used to dry briquette. It is a continuous batch belt dryer. The temperature of briquette dryer is 130-250 degrees, and the output of briquette dryer can reach 345678 91012141520 tons / hour. The length of briquette drying cabinet is composed of standard sections. In order to save space, three or five layers can be used to transport briquettes. At the same time, the briquettes are dried and dehumidified. The common ones are 3-layer 20 m, 3-layer 30 m, 5-layer 20 m, 5-layer 30 m, etc.
High efficiency and energy-saving slime dryer is a new type of drying equipment developed on the basis of belt dryer. The DW multi-layer belt dryer for briquette developed by Changzhou Haomai drying Engineering Co., Ltd. is of high efficiency, economical and reliable quality. The series of dryers have the advantages of fast drying speed, high evaporation intensity and good product quality. It is suitable for dehydrating filter cake like paste It can also be dried after granulation or rod-shaped material. Through continuous R & D and design, industrial experiments and production practice of many cooperative units, the technology of high-efficiency and energy-saving briquette dryer has been mature.
Working principle of briquette dryer:
Briquette with a large amount of moisture is pressed into briquette by the molding machine and evenly laid on the mesh belt. The mesh belt is generally made of 12-60 mesh stainless steel wire mesh and moved in the dryer by the drive device. The dryer is composed of several units. Each unit has an independent hot air circulation. Part of the tail gas is discharged by a special dehumidification fan. The waste gas is controlled by a regulating valve. The hot gas passes through the mesh belt covered with materials from bottom to top or from top to bottom to complete the process of heat and mass transfer and take away the moisture of materials. After the briquette is fed into the briquette net continuously, the temperature can be adjusted according to the demand. The upper and lower circulation units can be flexibly equipped according to the needs of users, and the number of units can also be selected according to the needs.
Performance characteristics of briquette dryer:
1. Air volume, heating temperature, material residence time and feeding speed can be adjusted to achieve drying effect.
2. The equipment configuration is flexible, and mesh belt flushing system and material cooling system can be used. Most of the air is recycled and highly energy-saving.
3. The unique air distribution device makes the hot air distribution more uniform and ensures the consistency of product quality.
4. The heat source can be steam, heat transfer oil, electricity or coal (oil) hot blast stove, etc. Choosing a reasonable heat source also greatly reduces the cost of consumables of dryer equipment, saves resources, and ensures the production profit, and also increases the service life of the machine
5. It is suitable for dehydrated vegetables, pellet feed, monosodium glutamate, coconut milk, organic pigment, synthetic rubber, propylene fiber, drugs, medicinal materials, small wood products, plastic products, electronic devices, aging, curing, etc.
6. The ball is designed from the upper low-temperature area and the tail low-temperature area. The coal ball is gradually heated from the low-temperature area and gradually heated from the high-temperature area, so as to avoid cracking and bursting of the briquette containing 8-10% moisture due to rapid heating, and the damage rate is low.
