The invention discloses a water distributor which runs stably and is leakage-free. The water distributor comprises a water distribution device, a compressed air distribution device, a transmission device, a pipeline connection device, a distribution device, a spray nozzle, a water distribution pipeline, and a compressed air distribution pipeline, wherein the transmission device is connected with an electric motor through a coupler or a belt, to drive the water distributor to rotate; the water distribution device and the compressed air distribution device adopt shaft seal, and the outlet pipes of the water distribution device and the compressed air distribution device are connected with the pipeline connection device or the water distribution device through sleeve pipes; and compressed air and water enters into the spray nozzle for atomization through independent channels; and then sprayed to the surface of a heat exchanger to form water film with a uniform thickness. Therefore, the heat transmission efficiency is improved.
Description
Technical field
The present invention relates to a kind of water-distributing device that is used for the evaporative cooling heat exchanger, form even moisture film at heat exchanger surface, strengthen the heat and mass transfer process of moisture film and air, improve heat exchange efficiency through rotation water distributing.
Background technology
Existing devaporizer is employed in heat exchange coil top water distribution more, because the effect of surface tension and viscous force, the uniformity of heat exchanger surface moisture film, integrality are all not ideal enough; And the steam partial pressure difference is a devaporizer heat and mass transfer process motive force in water film surface saturated air pressure and the primary air; When traditional water distribution manner formed moisture film at heat exchanger surface, most of water droplet and air directly acted on, and make air humidity significantly increase; Be that the water in air vapor pressure increases; The heat and mass motive force of moisture film and air reduces, and the air heat removal capacity fails to fill the wind utilization, so heat exchanger heat transfer efficient is low.
To the low reason of devaporizer heat transfer efficiency, on existing heat and mass transfer enhancement technical foundation, the applicant belong to seminar once proposed to utilize evaporation water compensating device (ZL2009103003918) in the heat exchanger side water distribution improve moisture film uniformity, improve mass transfer force; Because this evaporation water compensating device utilizes water droplet to be rotated automatically by the reaction force thrust unit that nozzle sprays at a high speed, therefore, pressure and air capacity that compressed air needs are very big; And air pressure is far longer than the required pressure of spraying, makes air compressor power increase sharply, and energy waste is serious; More serious is; The rotary body of this water-distributing device is sleeved on the intake tunnel, and rotary body and intake tunnel outer wall constitute cavity, through bearings; Therefore; The moving component of this device and the frictional force of stationary parts, sealing and device motive force constitute a series of insurmountable contradictions: 1) good airproof performance, and then install frictional force and sharply increase, thrust unit rotation required drive also sharply increases; Cause required compressed air pressure and air capacity to increase rapidly, air compressor machine power sharply increases; 2) sealing is poor, then leaks seriously, wastes a large amount of compressed air, causes compressor required motor power sharply to increase equally; 3) the thin metal fillings that produces in rotatablely moving of minute impurities in water or the compressed air or device can both be stuck in the slit between movement parts and the static element easily, and device is frequently stopped the rotation, and causes the heat exchanger can't heat extraction; 4) the water-locator leakage can make the lubricating oil of bearing spatter to heat exchanger surface, seriously undermines the uniformity and the integrality of moisture film; 5) compressed air contacts with the too early of water, makes air leaked by the water tank side, and the hydraulic pressure recovery tank is had to bring up to water-aspirator pressure close with compressed air pressure, is far longer than the required economic pressures of atomizing.
Because there is the slit in this water-locator all the time as there being the face of being association of activity and inertia of rotary body and stationary parts eventually, finds in the actual measurement; In any case the optimization means sealing is optimized and is improved wherein any one problem, all can worsen the other problem in above-mentioned five problems; Therefore; The problems referred to above can't solve all the time, must thoroughly improve from the cardinal principle of device, so this device can not be expired middle actual requirement of engineering.
Summary of the invention
Serious to said apparatus operation frequent shutdown, energy consumption waste, leak lubricating oil serious and that leak and weaken many critical defects such as moisture film uniformity, integrality, the present invention provides that a kind of rotation hutch water device is stable, energy consumption is low and leak free water-locator.
The technical scheme that addresses the above problem is: adopt water transportation and distrubution apparatus, compressed air transportation and distrubution apparatus, assembling pipe joint, distributor, water transmission and distribution pipeline and compressed air transmission and distribution pipeline, the frequent shutdown that the solution sealing problem causes, the critical defect that the energy consumption waste is serious, lubricating oil that leak serious and leakage weakens moisture film uniformity, integrality; Adopt motor that rotary power is provided; Reduce air supply and pressure, reduce air compressor machine required motor power rapidly, thereby reduce the water-locator energy consumption.
Beneficial effect of the present invention: when hutch water device according to the invention was worked, moisture film was even, complete, at utmost utilizes the heat and mass motive force of air and moisture film; Water-locator operation power of motor 50～100W does not have and leaks, and required compressed air pressure and air capacity sharply descend; Energy consumption is low, and is stable, do not have frequent shutdown cause can't heat exchange problem; Avoid bearing oil to weaken the uniformity and the integrality of moisture film, improve heat exchange efficiency.
