Water or air is usually used as a coolant to remove heat. There are wall coolers, spray coolers, jacketed coolers and serpentine coolers. Example: used for high-power silicon rectification and induction furnaces and medium-frequency furnaces, such as pure water, water, oil, oil and air cooling devices, such as Yueqing Yandang Mountain Cooler Co., Ltd. A well-known manufacturer of products in the country. The cooler is mainly composed of a partition wall, hybrid and regenerative exchanger. The working principle of the cooler, heat transfer calculation, structural calculation, activity resistance calculation and design procedure are more illustrated in the heat exchanger book. And detailed examples.
The generic term "cooling tower" is used to describe direct (open circuit) and indirect (closed circuit) heat sinks. While most have come up with a "cooling tower as an open direct contact heat sink", an indirect cooling tower, sometimes referred to as a "closed circuit cooling tower", is also a cooling tower. A direct, or open-circuit cooling tower is a means of sealing the interior of the structure to distribute warm water to feed it to the labyrinth package or to "fill it up." The fill provides a greatly expanded aviation, water evaporating to heat the air and the interface takes place. Cooling water, as it passes through by gravity, and passes over it in direct contact with the air. The cooling water is then collected in a cold water basin below which it is pumped back from the entire process to absorb more heat. The heated and humid air is filled with a sufficient atmospheric inlet from the air to leave the discharge point to prevent it from being caught in the cooling tower. The filling may include multiple, mainly vertical, wet surfaces on which the water (filled) or lateral splash elements create a number of layers of thin film (splash) with a large surface area of ​​water droplets cascaded. Indirect, or closed circuit cooling towers are not involved in air, liquid, usually FRP products FRP tank FRP roof fan FRP hood FRP cooling tower FRP biogas tank FRP desulfurization tower The water jet pump is directly contacted with water or glycol mixture and is cooled.
Manual working process: After the water filter [2] is connected to the pipeline system, the water enters the water filter from the lower water inlet. When the impurities in the water pass through the core, the volume is larger than the core hole, and the water is trapped on the core. When accumulating to a certain number, a certain pressure difference is generated between the inlet and outlet. (The filter precision diameter is different, the pressure difference is different, generally 0.15Mpa), manually open the drain valve, the sewage starts, the rolling handle, the rotation direction can be rotated in both positive and negative directions, every 10 seconds - 30 seconds to roll a grid, the handle points Each of the recesses is fixed, and the water flow reversely flushes the foreign matter adhering to the inner wall surface of the core. Until one rotation, the drain valve is closed and the manual drain is completed. If the user selects the automatic water filter, the optional differential pressure sewage discharge and regular sewage discharge 1. Differential pressure discharge: When the impurities accumulate to a certain number, the differential pressure signal between the inlet and outlet of the cooling water is used to backflush the sewage, that is, the electrical contact The pressure gauge turns on the control signal, the control mechanism opens the electric blowdown valve, and the electric reducer will run at a speed of 3-6 revolutions per minute. The water flow reversely flushes the impurity dirt attached to the inner wall surface of the core, and passes through the sewage pipeline. Discharge the drain valve into the cooling water outlet pipe and clear it for about 5-10 minutes. When a large debris is generated and the filter cannot be in place, the electric device should be operated in the opposite direction to wash away debris. 2. If you need to set the time of sewage discharge, set the cleaning and sewage discharge time within 0-99 hours, generally set to 12 hours for sewage discharge, and the time setting can be adjusted according to the water quality of the power plant. That is, the set time is started to start the electric reducer to reverse the exhaust valve, and the reverse back flushing is sequentially performed. Until the backlash of all the chambers is completed, the electric device is stopped, the electric recoil valve and the electric blowdown valve are closed, and the sewage discharge work is completed.
