The composition of tumble dryers generally includes racks, baskets, motors, fans and cabinets. Drying equipment often appears in the form of a drying line during the production process. According to the difference of process and field environment, each set of drying lines will be connected by different number of dryers; each rotation of the cage can be controlled by the system to achieve a separate positive and negative rotation, the work process can be set, can be freely removable one Without affecting the normal operation of the rotation of other sections.
The first two sections of the dryer and dryer B can adjust the speed independently, and the rest of the basket speed can be adjusted uniformly. The rotating speed of the cage is divided into three stages. The trolling speed can be set to high (48rpm), medium (40rpm) and low (30rpm) three-speed operation through the touch screen. Among them, the drying fan corresponding to each section of drying machine rotating cage starts with each section drying drying cage start, and can be manually closed after starting.
The same group of dryers and small conveyors are linked with the dryer. The dryer A reverses the linkage with the delivery blower. When the dryer reverses the pill, the pilling blower starts automatically. At this time, if the long conveyor is not started, the touch screen prompts you to select the direction of delivery. When one of the pilling directions is selected, the small conveyor in this direction is automatically started (if the small conveyor in the other direction is running, the operation is automatically stopped), and the first section of the dryer in this direction is started at the same time. (dry state). When the first section of the cage rotates in accordance with the set time, the cage automatically enters the inverted pill state, and at the same time, it automatically starts the second quarter of the cage forward rotation and enters the next drying cycle. The cage protective cover is equipped with a proximity switch. After lifting the cage protective cover, the rotating cage stops rotating, the protective cover is dropped, and the rotating cage continues to operate according to the control logic.
Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
