Technical field
The present invention relates to technical field of heat exchange equipment more particularly to a kind of heat absorption and cooling double-duty towers.
Background technique
The apparatus field exchanged with air progress heat is very extensive, in terms of will affect mankind's modern production and life side
Face, modern mechanical, electric power, medicine, food processing and petrochemical industry, there are also refrigeration air-conditioners, and air energy thermal pump assembly is not all from
Open cooling tower.
Cooling tower is to use water as circulating coolant, heat dissipation is absorbed from a system into atmosphere, infant industry is cold
But tower is to reduce a kind of device of water temperature.
Its type of cooling is to carry out cold and hot exchange after contacting using water with air flowing to generate steam, and heat is taken away in steam volatilization
Amount reaches the principles such as evaporative heat loss, convective heat transfer and radiant heat transfer to disperse the waste heat generated in industrial or refrigeration air-conditioner and drop
The evaporating radiator of low water temperature, to guarantee the normal operation of system, device is generally tubbiness, and therefore named is cooling tower, if being used to
Heat source tower can be called again by absorbing heat to air.
There are many cooling tower type, can generally be divided by draft type: 1. cooling stack；2. force ventilation is cooling
Tower；3. mixed ventilation cooling tower.It can be divided by the way of contact of water and air: 1. wet cooling tower；2. dry cooling tower；3. doing
Wet cooling tower.If can be divided by the flow direction of hot water and air: 1. counterflow cooling tower；2. crossing current (straight exchange) formula is cooling
Tower；3. mixed-flow cooling tower.It can be divided by application field: 1. industrial cooling tower；2. air-conditioning-type cooling tower.It can by level of noise
It is divided into: 1. plain edition cooling tower；2. low noise type cooling tower；3. super-low noise type cooling tower；4. ultra-quiet type cooling tower.By tower body shape
Shape can be divided into: 1. circular cooling tower: 2. square cooling tower.By water and air, directly whether contact can be divided into: 1. open cooling tower:
2. closed cooling tower (also referred to as sealed cooling tower, closed cooling tower).Other pattern cooling towers, such as jet flow cooling tower, nothing
Fan cooling tower etc..
Cooling tower is being the form of spray pond using initial stage, develops into later and pulls out air duct form, develops into nineteen twenty-four
For air blast ventilation form.Five sixties of twentieth century, cooling tower obtain important breakthrough, and axis circulates Cooling Tower as standardization
Tower is rapidly developed.
China has carried out a large amount of further investigations to cooling tower since nineteen seventies, achieves in the eighties
A large amount of research achievement, and push the fast development of domestic cooling tower industry.Continue to optimize the skills such as noise, power consumption, evaporation loss
Art index, while the appearance material of cooling tower is promoted, incorporate the overall quality of building.
Industrial cooling tower is primarily upon following technology trends: a, water-saving technology at present: by cooling tower gas chamber two
Side increases efficiently air-cooled heat-exchanger rig, cooling of the recirculated water in the device and does not generate the evaporation of water, and the heat exchange amount of the part accounts for
The 15%~20% of total heat exchange amount, therefore compared with conventional chilling tower, average annual water-saving rate (in terms of evaporated water) is up to 15~20%；
B, disperse fog technology: the relative humidity of discharge air-flow is exported from air duct by reducing, to reduce and generate in atmosphere mixed process
Vapor condensation, realize the plumage mist emission reduction that runs under low temperature environment；C, it noise reduction technology: first has to find out cooling tower buzz
Source, cooling tower buzz is mainly from following four part: 1, fan noise；2, water drenching noise；3, blower retarder and motor
Noise；4, cooling tower water pump and additional noise.It can be subtracted by increasing air inlet silencer, exhaust outlet silencer, blower motor
The silencing apparatus such as vibrating device, silent packing, compared with conventional chilling tower, noise reduces by 10~30 points at 1 meter outside cooling tower
Shellfish；D, power-saving technology: accomplish tower pressure head and wind turbine energy consumption by minute design lower；In high pressure of return water
In circulation, by rationally designing, using hydrodynamic draught fan technology, high backwater pressure head is rationally and efficiently used, saves fan electricity
Machine electricity consumption；Had according to Various Seasonal and environment temperature to cooling tower group's fan motor by automation control and adjusting
Effect control, reaches intelligent control and energy-efficient purpose；E, the high-order technology of water catchment of large-scale cooling stack: the technology is reduced
The static lift of water circulating pump simultaneously reduces cooling tower water drenching noise, compares conventional chilling tower, and operation power consumption is greatly reduced and noise is controlled
Reason expense.The cooling tower used in nuclear power field requires can be higher than the requirement of cooling tower used in other fields, and developing inland nuclear power is
The direction of China's nuclear power developing.Inland nuclear power necessarily uses cooling tower.The water of nuclear power is twice than thermoelectricity, so cooling tower drenches
Water area is larger, and opposite air quantity and wind pressure are also big.The market of nuclear power cooling tower will increase rapidly 5~10 years from now on, energetically
The Nuclear Power Development development trend that cooling tower technology is from now on, therefore the cooling of research and probe high efficiency wind, especially aerofoil fan
High efficiency, low cost operation is also imperative.According to existing the relevant technologies, We conducted comparative analyses: belonging to turbine
The fanjet of the exhaust apparatus equipment of tool is fewer when the bigger energy consumption of turbofan blade diameter, also more embodies energy-efficient excellent
Gesture, this sufficiently demonstrates the more big more energy-efficient benefit of aerofoil fan diameter, present its bigger efficiency of wind power generation blade diameter
It is higher, but its bigger noise of axial flow blower diameter also can be very big, because amplitude of fluctuation produced by fan blade diameter is excessive is big, no
Blade limit eddy-current loss is only had, also will appear vibrating noise puzzlement.So being reduced again to realize scale air quantity purpose
Noise also wants low energy consumption to run, so wind-force blade radial can be connected to using a kind of solid leaf outlet air drum type brake aerofoil fan
Other end is connected on the component of axle center again on outlet air cylinder, all fan blades are linked together to reduce wind with solid leaf outlet air cylinder
Leaf vibration amplitude and frequency play the role of preferably reducing noise, and rotation function is not blower axle center to drive the rotation of fan blade
Turn, but realize the transmitting of rotation function by the power transmission wheel of blower periphery, this turbine installation can be used as the wind of cooling tower
Fan, existing aerofoil fan are entirely to export rotation function by axis, and fan blade edge also will appear eddy-current loss.Therefore, having must

But at a certain distance from tower air inlet, setting is not less than the sound barrier of cooling tower air inlet, and reaching reduces air inlet noise to sensitive spot
The effect of influence.3. drop energy-eliminating device method is the laying drop energy-eliminating device on pond of cooling tower face, water drenching and pond face phase are reduced
The noise of sending is hit, to achieve the purpose that reduce cooling tower buzz.
Drop energy-eliminating device has substantially no effect on the ventilation quantity of cooling tower, is also not take up the place in addition to cooling tower.There are also coolings
Tower to the sound of the wind of its Main Noise Sources axial flow blower take at air outlet install additional sound proof housing disposal options (noise elimination, which is covered with, to disappear
Sound plate, noise elimination mineral wool, the compositions such as fixed net of eliminating the noise) and when effectively raising the outlet air of axial flow blower with software noise elimination mineral wool
