——Huanjia drying
In recent years, various industries have put forward many requirements for energy conservation and rational use of energy. They have also taken many effective measures. Especially for the utilization of coal, electricity and water resources, factories and mines must pay attention to them. Link. The following is a description of the energy saving and consumption reduction of the drying equipment room.
1. The application of the frequency converter in the drying equipment greatly saves energy
In the drying equipment, the fans generally used are relatively large, and the fans are almost continuously operated, and the inverter can save 30% energy. If a dust collector is added to the rear end of the dryer, it will save twice the electricity bill, because the dust collector is equipped with a larger fan. On the other hand, the noise of the overall equipment will be much lower after using the inverter, and the service life of the equipment will be extended.
2. For the choice of heat source, consider the idea of ​​energy saving and consumption reduction.
Drying equipment is a device that uses heat to dry materials with high water content. The use of heat energy plays an important role in the drying process. If the heat cannot be taken away in time or the circulation is not smooth, it will affect the whole system.
There are many forms of heat energy generation, such as electric heating pipes, natural gas, diesel oil, and coal can generate heat energy through certain equipment. The heat sources provided by our company's drying equipment include electric heaters, gas burners, fuel burners, coal-fired furnaces, etc. The application of electric heating is widely used in small drying equipment, generally used in the laboratory, it does not have any pollution problems, and the heating is faster. The burner is mainly used in large-scale drying equipment and plays a decisive role in industrial production. In recent years, with the rise of the electronics industry, drying equipment has also developed considerably. For example, the DTP-300 drying equipment has an hourly water evaporation of 300KG/H. If the traditional electric heating method is used, the electricity consumption is 265kW per hour. -h, and the gas consumption per hour using the gas burner is only about 45m3, compared to the energy saving effect of the heat source using the gas method is obvious. Moreover, the induced draft fan of the drying device used by the above-mentioned user is controlled by a frequency converter, and the degree of automation is relatively high, which saves a lot of manpower and material resources. The coal-fired hot blast stove is also widely used as a heat source for dryers. It can be used directly in applications where material requirements are not critical. For example, various types of dryers are used in the production of mold flux for various steel mills. In the case of strict requirements on materials, direct-fired hot blast stoves cannot meet the requirements of users. It is necessary to add heat exchange devices to reduce the degree of contamination of materials.
3. Requirements for the overall insulation performance of the equipment
The drying equipment is a closed micro-negative system, and the loss of heat in any part will affect the entire equipment. Since the main tower body of the dryer has a large volume and surface area, for this reason, the drying equipment produced by our company uses 200 mm thick insulation material and color steel plate for the main tower housing of the dryer. This is beneficial to prevent the loss of heat and at the same time increase the appearance. However, in the case of special materials, other parts of the drying equipment, such as pipes and dust collectors, are required to be insulated, otherwise the process and technical requirements cannot be met.
4. Core components of drying equipment
The design of the hot air distributor plays an important role in energy saving and consumption reduction of the entire system. The heat energy of the system can be contacted with the material through the distribution of the hot air distributor, which is directly related to the dryness of the product. The technicians have made great efforts in the design of the hot air distributor, and researched the unique hot air distribution system double-layer hot air distribution structure design, so that when the hot air enters the upper part of the drying tower, the air volume in each direction is uniform and dry. The inside of the tower rotates downwards, which evaporates water more effectively and prevents the walls from sticking inside the tower, which has won praise from users.
5. Recycling of cooling water
Larger fans and pumps are used in the drying equipment, and the cooling of the motor is cooled by circulating water, which saves a lot of water resources.
With the continuous development of the drying industry, the application of drying equipment is becoming more and more extensive, but there is still room for improvement in key technologies (such as drying of materials with high sugar content), and in addition to the reuse of heat energy. Great effort requires joint research and innovation from the peers to enable the drying industry to develop rapidly .
