Description
Technical field
The present invention relates to a kind of circulating water cooling systems of pump coupled heat, belong to industrial circulating water technical field.
Background technology
The existing circulation overwhelming majority of large enterprise uses traditional open cooling tower, and on the one hand its fresh water disappears
Consumption is big, and the water of consumption accounts for the 2/3 of industrial water consumption, even more；Another aspect open cooling tower cooling water and air are straight
Contact, substantial amounts of impurity enter system, cause corrosive pipeline and fouling, is forced to add a large amount of chemical agents, heat exchange efficiency is low
The problem of lower, will be on the rise.Recently, many enterprises begin attempt to, using closed cooling tower, pipe heat exchanger is placed in tower,
It exchanges with circulating water heating to ensure cooling-down effect by the air of circulation, shower water.Due to being closed cycle, it can ensure water
Matter is not contaminated, protects the Effec-tive Function of main equipment, improves service life, while significant effect of saving water and energy.
However, equipment size and the excessive further development that restrict closed cooling tower in recirculated water field of floor space.
This is because closed cooling tower is with reference to local annual highest wet-bulb temperature and maximum heat transfer temperature difference when design, change
Work enterprise is generally 40 DEG C -30 DEG C, and in most of the time, such as morning, evening among spring, autumn, winter or one day
On, temperature is than relatively low, far below design standard, at this time closed cooling tower and full load operation is not required, it may also be said to
It is more than needed that heat exchange area, which has quite a few, this has resulted in the waste of equipment size and floor space.With open cooling tower
It compares, closed cooling tower is limited by the steel frame construction and manufacturing process of itself, can not like that be done everywhere to hyperbola open type tower
In reason amount incomparably per hour, the result to break the whole up into parts is exactly that the overall floor space of closed cooling tower is excessive.

Coupling, heat pump system employs series-parallel mode, improves operational efficiency.But it is the same with CN201010005518.6,
It is air-conditioning system service just with the hot junction of heat pump system and cold end, and starting point does not all lie in the improvement of heat exchange tower,
Also without external circulating water line, circulation can not be applied to.
CN201310699608.3 discloses a kind of heat pump heat supply demisting water-saving cooling tower, really utilizes heat pump techniques
Cooling tower is improved, in terms of being mainly reflected in demisting, i.e., the heat source generated using heat pump is used for heating blower fan of cooling tower
The humid air of outlet reduces the relative humidity of Output air of water cooling tower, and then defogging effect.But its shortcoming also compares
Substantially, on the one hand its heat pump system and cooling tower are still two independent equipment, are not coupling in a device, the two is led to
Piping and heat exchanger are connected, and using multistage heat exchange, structure is more complicated, and heat loss is serious；On the other hand, heat pump is necessary
Work round-the-clock can just have both refrigeration and defogging effect, and compare traditional cooling tower, and energy consumption is very high.
CN201510419893.8 discloses a kind of water type closed cycle water air cooling system and method, it is proposed that cooling
Tower level-one cools down, the thinking of heat pump two level cooling, but its heat pump system and cooling tower are still two independent equipment, and its
The heat for the recirculated water that needs are cooled down by heat pump has been transferred to another strand of cooling water again, be then again fed to cooling tower into
Row cools, and has been come back to equal to heat to be treated further through another mode in cooling tower, this is clearly not
Reasonably.
CN201610341832.9 discloses a kind of three dimension high efficiency evaporation and heat-exchange system, it is also realised that cooling tower
The problem of volume is larger, and the most of the time operates at part load, therefore propose and utilize vapor-compression type refrigeration system（Heat
Pumping system）Strengthen the thinking of refrigeration, evaporator is placed in sink, condenser is placed in axial flow blower exit and also compensates for
The deficiency of CN201510419893.8 patents.But the patent overemphasizes vapor-compression type refrigeration system, by increasing or reducing
Compression-type refrigeration ability enables the device to adapt to various weather conditions, and energy consumption is very high, the reduction to equipment volume
And it is limited, and the patent abandoned closed cooling tower biggest advantage i.e. heat exchange coil, shower water, wind three-phase heat transfer with
And sensible heat and vaporation-type latent heat synergistic effect, but become water and heat transfer water, coil pipe and hearsay heat, and when temperature is higher
What is really worked is that the evaporation latent heat of coil surface water takes away most of heat.
