Description

A kind of no machine driving jet stream is sprayed adjusting cooling device

Technical field

The utility model belongs to longitudinal ventilation with jetblower cooling technology field, and specifically a kind of no machine driving jet stream is spraying adjustable Cooling device.

Background technique

Currently, the prior art commonly used in the trade is such that commonly using open type counter-flow cooling tower both at home and abroad mainly includes tradition Mechanical draft filling cooling tower, traditional mechanical draft no-padding and spraying cooling tower, conventional hydraulic blower fan non-stuffing gravity water return two Secondary spray cooling tower.

Traditional mechanical draft filling cooling tower is the forced draft of electric machinery blower, filler cloth liquid mass transfer, by being driven by electricity Mechanical fan has mechanical gear reduction component, has filling-material structure.There are several big problems: 1. persistently consuming energy, because leaning on motor driven wind Machine operating；2. needing periodic maintenance, expire replacement, because there are mechanical fan gear reduction components for nuclear structure；3. reliability continues Decline, because the service lifes such as machine driving bearing portion part limit, with long-term continuous operation, core mechanical fan deceleration transmission system System will appear the integrity problems such as vibration aggravation, running balance failure；4. periodic maintenance is needed to replace, cold effect gradually declines, because of core Core structure includes filling-material structure, and with long-term continuous operation, the aggregation such as phycomycete growth, dust, filler gap will gradually block, and make Cheng Lengxiao decline, therefore need periodic cleaning maintenance replacement.

Traditional mechanical draft no-padding and spraying cooling tower is electric wind forced draft, straight up with fixed nozzle group Spraying mass transfer is concentrated, by power-driven machinery blower, has mechanical gear reduction component.There are several big problems: 1. persistently consume energy, because It is operated by motor driven blower；2. needing periodic maintenance, expire replacement, because there are machine driving deceleration components for nuclear structure；3. can It is continued to decline by property, because the service lifes such as machine driving bearing portion part limit, with long-term continuous operation, core mechanical fan subtracts Fast transmission system will appear the integrity problems such as vibration aggravation, running balance failure；4. the big temperature reduction performance of flow resistance is poor, because of its nozzle Spraying straight up in component set, spray flow concentrates on tower center, cause tower bottom ventilation resistance is very big, cold air air inflow substantially It reduces, it is poor to eventually lead to full tower temperature reduction performance；5. operating condition is non-adjustable, operating condition narrow range is unable to satisfy user according to production The actual demands such as load adjustment circulating cooling flow and hydraulic pressure, are unfavorable for industrial application.

Conventional hydraulic blower fan non-stuffing gravity water return secondary spray cooling tower promotes wind for hydro powered machinery swirling flow atomizing Machine device forced draft is atomized mass transfer, and primary atomization temperature lowering water cools down again by spraying by gravity water return secondary.There are several big problems: 1. There are still reliabilities to continue to decline problem, because nuclear structure swirling flow atomizing propulsive fan device remains as mechanical transmission component, It is limited by drive bearing component service life, and with long-term continuous operation, rolling bearing component loses continued wear, dynamic balancing Effect, reliability will gradually decline so as to cause operational failure, to cause to shut down；2. there is still a need for periodic maintenance, expire replacement, Because nuclear structure swirling flow atomizing propulsive fan device remains as mechanical transmission component, operating bearing interval is smaller, when shutting down Between it is too long or bring larger size impurity into or foreign matter will cause bearing interval viscous or blocking, thus need inspect periodically, clear up, Jiggering inspection, bearing run to some cycles, need to remove replacement；3. heat reflux flow resistance is big, temperature reduction performance is poor, because its gravity returns The secondary spraying layout of water is similar to traditional machine power ventilating atomization cooling tower, equally spraying straight up using nozzle assembly concentration, Spray flow concentrates on tower center, and spray flow whereabouts inverted ventilation is discharged from tower bottom, causes tower bottom ventilation resistance very big, temperature reduction performance is difficult to Reach best；4. being limited by atomization propulsion device performance, single column spray density is far below traditional machine power tower, for enhancing atomization effect Fruit, nozzle diameter is small, easily blocks, practical temperature reduction performance is poor, compares far from induced cooling tower；5. operating condition is non-adjustable, Operating condition narrow range is unable to satisfy user according to produce load and adjusts the actual demands such as circulating cooling flow and hydraulic pressure, unfavorable In industrial application.
