Jingdezhen Jingdezhen round counterflow closed cooling tower cooling tower cooling tower theory is a highly integrated, highly experimental system of discipline. Our scientific and technical personnel in the years through the cooling tower thermal test trials on the basis of comprehensive test data processing, a computer draw (35 * 20-75?) Trapezoidal wave water filling volumetric mass coefficient Bxv, choose the best gas-water ratio, the best cross-section of water load, height range and packing section gas load high-efficiency, in order to determine the volume of the filler, and the shape and structure of fluid dynamics point of view integrated design of the tower, according to the test to estimate ventilation resistance, Reference fan characteristic curve and optimal selection of test data, and achieve compliance with the requirements of wind turbine noise standards and match the motor, the cold efficiency, energy consumption, noise, appearance reach an optimized system effects. Select a cooling tower performance and design parameters: 1) the standard conditions: inlet temperature t1 = 37 ℃, water temperature t2 = 32 ℃, the design wet bulb temperature τ = 28 ℃, namely water temperature Δt = 5 ℃, cold sites High t2-τ = 5 ℃ 2) temperature conditions: inlet temperature t1 = 43 ℃, water temperature t2 = 33 ℃, the design wet bulb temperature τ = 28 ℃, namely water temperature Δt = 10 ℃ cold pieces of high-t2-τ = 6 ℃ 3) high temperature conditions: water temperature t1 = 60 ℃, water temperature t2 = 35 ℃, the design wet bulb temperature τ = 28 ℃, namely water temperature Δt = 25 ℃ cold pieces of high-t2-τ = 8 ℃ 2 When the choice of notes of water Q, water temperature t1, t2 and design water temperature wet bulb temperature τ, and then determine the thermodynamic model based on the performance curve. Thermal performance curve. On the outside of the curve table conditions can be thermodynamic calculation, the filler volume bulk transfer coefficient β × ν follows: 1.2 times the nominal flow rate: β × ν = 18600 1.0 times the nominal flow rate: β × ν = 17800 0.8 times the nominal When the flow: β × ν = 17000 3, running half the weight of the water in the tower pressed deep computing, if calculated according to filled with water should be multiplied by 1.5. 4, the series of cooling towers for the coldest average temperature not lower than -10 ℃ areas, users should be made at low temperatures freeze prevention requirements, in order to configure watering diversion ring, do not make the water flow to the blinds. Intermittent operation during the winter, can be added in the tank heating tube. This series of regional cooling towers for the coldest average temperature not lower than -10 ℃, the user should be made at low temperatures freeze prevention requirements, in order to configure watering diversion ring, do not make the water flow to the blinds. Intermittent operation during the winter, can be added in the tank heating tube. 5, circulating water turbidity is not greater than 50 mg / l, no more than a short period of 100 mg / l, not including oil and mechanical impurities, take measures to stabilize the algae and water if necessary. 6, for the water temperature does not exceed 60 ℃, such as when ordering more than can be explained, the Division I resolved from the selection. Nominal flow pore water distributor, 8, into the water pressure of about 2-5 meters of water, the design pressure is not too high, otherwise it will produce the phenomenon of floating water. 9, motors, fans are supporting the supply, the need to Division I sent on-site installation or technical guidance, plus fees. 10, when the user needs to direct absorption tower at the tower, install "Automatic water supply", "rapid water supply," "outfall" "overflow pipe" when ordering highlight.
