The cooling tower is provided with double composite water distributing devices and a heat transmitting and exchanging device, namely that the cooling tower is simultaneously provided with a gravity pool type water distributing device and a low-pressure pipe type water distributing device; a PVC right-angle refractive wave material filling device is arranged corresponding to the pool type water distributing device, and a PVC oblique wave material filling device is arranged corresponding to the low-pressure pipe type water distributing device. Due to the adoption of the structure of transversal crossflow heat exchange and vertical reverse flow heat exchange which are simultaneously carried out in the tower between hot water and air flow, the present invention can improve the average heat exchange rate in the integral limited space of the cooling tower and improve the thermal performance of the cooling tower more than 40%.
Description
(1) technical field:
The invention belongs to the industrial circulating water cooling technology, mainly propose a kind of efficient combined cooling tower with double heat exchanges.
(2) background technology:
The circulating water cooling device of big yield circulatory system use both at home and abroad has two kinds at present: counterflow cooling tower and cross flow cooling tower.Counterflow cooling tower and cross flow cooling tower are all according to the theoretical design of water evaporative cooling, be industrial cycle hot water, be sent to the water-distributing device that the cooling cat head is installed with water pump through upper hose, promptly be transported to tubular type (adverse current) or pond formula (crossing current) water distribution system, hot water evenly is sprayed onto on the liquid distribution packing sheet by the nozzle of water distribution system, when hot water flows through packing sheet from the top down, form uniform moisture film, under the effect of the axial flow blower that cat head is installed, cold air is inhaled in the cooling tower from the air inlet of cooling tower, passes behind the packing and is extracted out outside the tower by blower fan.In counterflow cooling tower, air-flow and flow reversal are flowed, and promptly air-flow flows vertically upward from tower bottom air inlet, and hot water flows through packing sheet from the top down, falls into the cooling tower lower sump.In cross flow cooling tower, air-flow and current are orthogonal mobile, be that air-flow passes packing from tower both sides air inlet level, hot water is from the nozzle ejection of pond, cat head both sides formula water-distributing device, be sprayed onto on the packing sheet equably, after hot water flows through packing sheet from the top down, fall into the cooling tower lower sump.When hot water was downward through packing sheet, evaporation absorbed heat and carries out heat exchange with the cold air of coming in from the cooling tower air inlet, and the heat that cold air absorbs hot water is heated outside the back discharge tower, after hot water is cooled, recycles thereby flow to the cooling tower lower sump.Counterflow cooling tower and cross flow cooling tower are two kinds of reasonable chilled water units, are extensive use of both at home and abroad at present.But there is a common defective in they, because the process structure decision of reverse-flow and cross flow cooling tower at present own, must by enough smoothly the air chamber flow field form, the limited cooling heat transferring space of cooling tower is not fully utilized, so, can not give full play to the service efficiency of cooling device, the whole confined space evenly heat of cooling tower exchange efficiency is lower.In addition, all there is the serious defective of severe cold freezed in winter in reverse-flow and cross flow cooling tower, though taked many ice measures that disappear not very good.
(3) summary of the invention:
Purpose of the present invention promptly is to propose a kind of efficient combined cooling tower with double heat exchanges, thereby fully develops, utilizes the effective heat exchange space, improves the utilization rate of the effective heat transfer space of cooling tower, improves cooling effect and solves the problem of cooling tower freezed in winter.
The technical scheme that the present invention finishes its invention task proposition is: be provided with dual compound water-distributing device and heat transmission switch, promptly be provided with gravity pond formula water-distributing device and low pressure tubular type water-distributing device simultaneously, and corresponding gravity pond formula water-distributing device is provided with PVC right-angle refracted extender device, and corresponding low pressure tubular type water-distributing device is provided with PVC oblique wave packing device; Cold air enters horizontal cross and current and is orthogonal mobilely from both sides, carry out the quadrature heat exchange; From flowing with flow reversal vertically upward down, carry out reverse heat exchange again; The cold air that promptly enters in the tower carries out mobile and twice heat exchange of vertical reverse flow of quadrature transverse simultaneously with hot water.
The wind guiding louver plate is installed in the outside of cooling tower both sides air inlet, make cold air evenly flow in the cooling tower, shutter board installed inside PVC right-angle refracted extender device, gravity pond formula water-distributing device is set on right-angle refracted extender top, right-angle refracted extender will form uniform moisture film from the hot water of pond formula water-distributing device ejection, flow from the top down along packing sheet, hot water carries out the quadrature heat exchange with the cold air of bottom horizontal flow sheet in flowing to the process of collecting-tank.At the cooling tower middle part, the following installation low pressure tubular type water-distributing device of air duct device, water collection device is installed on tubular type water-distributing device top, PVC oblique wave packing device is installed below the tubular type water-distributing device, this slope packing will form uniform moisture film from the hot water of tubular type water-distributing device shower nozzle ejection, hot water carries out reverse heat exchange with the cold air that upwards flows from the cooling tower lower vertical from tubular type water-distributing device shower nozzle ejection flows downward the process of the collecting-tank of falling the cooling tower bottom.
The recirculated water upper hose is delivered to gravity pond formula water-distributing device and low pressure tubular type water-distributing device respectively with hot water.
It is mobile that its characteristics of cooling tower of the present invention are that cold air is orthogonal from the both sides air inlet horizontal cross of cooling tower and current, carries out heat exchange, flow into cooling tower inside after, big portion air-flow from flowing with flow reversal vertically upward down, carries out heat exchange again; Cooling tower adopts hot water and air-flow to carry out simultaneously in tower that quadrature transverse flows and the structural design of two kinds of heat exchanges of vertical reverse flow, can make cooling tower dual packing the degree of depth with highly utilize the space to obtain reasonable configuration at cooling tower limited; Thermal performance can improve more than 40% than other tower.In addition, during severe winter the pond formula water dispensing apparatus of cooling tower is closed, make cooling tower along the air inlet inboard not water distribution just can solve the problem of cooling tower freezed in winter, the be cooled right-angle refracted extender device shielding of tower air inlet of the noise that the drenching with rain and dabble of counterflow cooling tower produces, it is outer and be overcome to spread out of tower.
