Description
Technical field
It is spraying cold that the invention belongs to ventilating and cooling technical field more particularly to a kind of ultralow flow resistances and noise type Multi-stage jet
But method and device.
Background technique
Currently, the prior art commonly used in the trade is such that currently, common unregulated power blower or non-filling energy conservation both at home and abroad
Environmentally friendly cooling tower mainly includes traditional machine power ventilating atomization cooling tower, Conventional gravity return water jet stream spray cooling tower and new multistage
Jet stream is sprayed gravity water return Blower-free non-filling type cooling tower etc..Traditional machine power ventilating atomization cooling tower is forced for electric wind
Exhausting is concentrated spraying mass transfer straight up with fixed nozzle group, has blower, non-filling, belong to non-energy saving and environment friendly cooling tower.It passes
System mechanical draft spray cooling tower, there are several big problems: 1. the big temperature reduction performance of flow resistance is poor, because its nozzle assembly is concentrated straight up
Spraying, spray flow concentrates on tower center, and spray flow falling speed reaches 0.9m/s, and the inverted ventilation for generating 0.9m/s is discharged from tower bottom,
It causes that tower bottom ventilation resistance is very big, cold air throttle flow is greatly decreased, it is poor to eventually lead to full tower temperature reduction performance；2. noise is big, because
Its electric wind structure exists, and vibrating noise is larger, while bottom spray flows down the new noise of overboard increase；3. persistently consume energy,
Because its electric wind structure determines.Conventional gravity return water jet stream spray cooling tower, " the gravity water return secondary injection spray of the prior art one
Mist propulsion aeration cooling tower "；For only with the spray cooling tower of swirling flow atomizing propulsion device mass transfer cloth liquid, Blower-free, non-filling,
Belong to energy saving and environment friendly cooling tower.Conventional gravity return water jet stream spray cooling tower, there are several big problems: 1. heat reflux flow resistance it is big,
Temperature reduction performance is poor, because its gravity water return secondary is laid out similar to traditional machine power ventilating atomization cooling tower by spraying, equally uses nozzle
Spraying straight up in component set, spray flow concentrates on tower center, and spray flow falling speed reaches 0.9m/s, to generate
The inverted ventilation of 0.9m/s is discharged from tower bottom, and the hot wind of discharge will lead to heat and be back to tower body lower part air inlet, while causing tower bottom logical
Wind resistance is very big, cold air throttle flow is greatly decreased, and secondary mist cooling performance is had a greatly reduced quality；2. noise is big, because of its secondary spray
Spray water is concentrated, and large area water flow falling impacts tower bottom generates new biggish noise；3. being limited by spray propulsion performance
System, cooling tower spray density is small, occupied area is bigger, considerably increases construction cost；4. it is limited by spray propulsion performance,
