As an important part of the drag system, offset paper plays an important role in the national economy. Its use has penetrated into almost all walks of life. It is an important guarantee for industrial, agricultural and national defense construction and normal life of the people, thus ensuring offset paper. The normal operation is very important, and the incidents that cause the offset paper to burn or even cause major safety accidents are not uncommon. According to incomplete statistics, the electricity consumed by the offset paper in the country is tens of millions of degrees per year, and the offset paper is burned. The number is more than 200,000 times, the capacity is about 0.4 billion kilowatts, the electromagnetic wire consumed for maintenance is about 50 million kilograms, the repair cost is 2 billion yuan, and the loss caused by the suspension of production is an incalculable huge number. . Next, let's take a closer look at offset paper and light paper.
The performance characteristics of offset paper: dry steam heating method, the main principle is that when adding steam to the air, it will not affect the air temperature, but if the humidification amount in the air is very high, and the machined workshop personnel and indoor environment In the case of self-heating, the temperature will rise slightly. The area of ​​the machine shop for machining is large, and the amount of humidification of the air offset paper is large, resulting in a temperature increase of 1-2 °C. At this time, it is necessary to cool down the treatment, which in turn will increase the energy consumption of the mechanical equipment.
Especially when the two seasons transition or the outdoor temperature is not uniform, the method of increasing the fresh air ratio can be used to reduce the indoor air temperature. However, if the outdoor air is dry in this season, if the wind is excessive, the burden of the offset paper will be obviously increased. As a result, the temperature in the machine shop is greatly increased, and the humidity is difficult to guarantee. On the one side, it is necessary to humidify with dry steam, and on the other side, the treatment method of turning off the refrigerant to cool down will cause great energy consumption of mechanical equipment.
By comparing the humidification methods of various offset papers, the use of gas-water mixing cold fog humidification is the best way to control the temperature and humidity with high precision machining in the mechanical manufacturing workshop. Because: the effect of spray and humidification of offset paper is not obvious, the water consumption of mechanical equipment is huge; the control of wet film humidification is not accurate enough (for hysteresis control), and the wet film itself uses hydrophilic material to filter air, dust More, long-term operation of mechanical equipment is prone to bacteria, easy to cause respiratory problems in mechanical designers; high-pressure micro-fog humidification requires a large amount of work, high failure rate and not stable enough. The gas-water mixing cold mist humidification method has the characteristics of sensitive sensitivity, strong ability to generate fine mist, and linear adjustment of spray volume. It can fully guarantee the temperature and humidity control requirements of the mechanical manufacturing workshop, and can completely replace the dry steam offset paper in spring and autumn. With significant energy savings.
The application of offset paper is very extensive. It is mainly divided into two types: horizontal axis wind-coated paper and vertical axis wind-coated paper. The horizontal axis wind-off offset paper is divided into two types: lift type and resistance type. Most horizontal axis wind-coated papers have a wind-driven device that can rotate as the wind direction changes. The vertical axis wind offset paper does not need to be windy when the wind direction changes. At this point, it is a big advantage over the horizontal axis wind offset paper, which simplifies the structural design and reduces the gyroscopic force when the wind wheel is against the wind.
