Abstract
The present invention relates to a high-effective low-temperature cooling tower. It is composed of the following several portions: energy recovery heat exchanger, spray stage, exhaust blower, water tank, water distribution system and machine unit external shell. Said invention also provides its working principle and concrete operation process.
Description
Technical field
The invention belongs to the cooling device in industrial cycle water system and the air conditioning cooling water system.
Background technology
Traditional cooling tower mainly contains crossing current and two kinds of forms of adverse current, directly enters cooling tower and the wet exchange of recirculated water generation heat cooling circulating water thereby the sort of mode all is the outdoor air that adopts, and the fiducial temperature of its cooling is the wet-bulb temperature of outdoor air.And when some needed the lower cooling water of temperature, above-mentioned two kinds of cooling towers can not be accomplished.
In the water cooled refrigeration unit, its condenser also is that the recirculated water that relies on cooling tower to provide is cooled, and when the temperature of recirculated water is low more, the refrigerating efficiency of refrigeration unit will be high more, thereby power consumption is just few more.
Therefore exploitation has social benefit and economic benefit widely with the popularization high-efficient low-temp cooling tower.
Summary of the invention:
The purpose of this invention is to provide a kind of low-temp cooling tower efficiently, key technology of the present invention is to have increased a plate-fin energy to reclaim heat exchanger in traditional cooling tower front, this heat exchanger is made up of two crisscross wind passages of crossing of isolating mutually, and vertical passageway and horizontal channel are formed.
The horizontal dry passage that fresh air at first enters heat exchanger enters the recirculated water spray section then, then comes out from the below of spray section, returns heat exchanger, and enters the vertical wet channel of heat exchanger from the below of heat exchanger.In this process, the fresh air that enters heat exchanger at first carries out heat exchange by precooling with the air draft of cooling tower, its air dry-bulb temperature and wet-bulb temperature all have been lowered, just the heat exchange fiducial temperature of air and recirculated water has reduced in the cooling tower spray section, and the recirculated water of processing will be lower than the temperature of the recirculated water of traditional cooling tower processing.
Air and water take place in spray section in the process of the wet exchange of heat, be that the heat that relies on the evaporation of part water to take away remainder water comes cooling circulating water, steam after the evaporation has entered in the air, air humidity has increased greatly, but the heat exchange that caused by the temperature difference has simultaneously taken place with water in air, and the temperature of air decreases.This air handling process is the process of a humidifying cooling.
Temperature decreased after air came out from spray section, enter again in the vertical wet channel of heat exchanger, here She Ji vertical passageway is that wet channel is in order to improve the utilization rate of air, if what adopt is dry passage, air draft in the vertical passageway will be the process of wet intensification such as a grade, the heat of its heat of taking away for relying on temperature to raise and take away with the sensible heat form.What the design adopted is wet channel, and air promptly has the exchange of heat wet exchange of measuring also to be arranged, the heat of its heat of taking away for relying on temperature and humidity to raise and take away with complete hot form simultaneously in wet channel.Therefore the heat that adopts wet channel, air to take away will be bigger than the heat that adopts dry passage to take away, and the thermal loss of fresh air in horizontal dry passage is just big, and temperature just is even lower.
To be starkly lower than the circulating water temperature that traditional cooling tower provides through the circulating water temperature after this high-efficient low-temp cooling tower processing, can provide temperature lower cooling water for the industry cooling, simultaneously, because the temperature of cooling water reduces, taking away under the situation of same heat, can strengthen the Inlet and outlet water temperature difference of cooling water, thereby can reduce cooling water flow, therefore can reduce the conveying energy consumption of recirculated water.
When this high-efficient low-temp cooling tower is used for the water cooled refrigeration unit,, the refrigerating efficiency of refrigeration unit will be improved, thereby energy consumption is just few more because the temperature of cooling water reduces.
When this high-efficient low-temp cooling tower was used for dry area and uses, outdoor air was relatively drier, adopts this high-efficient low-temp cooling tower will obtain the more cold water of low temperature, and can directly use in the air-conditioning system to fan coil or air-conditioning unit provides cold water to use.
Description of drawings:
Figure one is the schematic diagram of high-efficient low-temp cooling tower of the present invention, 11 are plate-fin energy recovery heat exchanger, 12 is spray section, and 13 is exhaust blower, and 14 is water tank, 31 is the cooling tower water outlet, 32 are the cooling tower water inlet, and 33 is the spray section water distribution, and this part water yield is bigger, account for the overwhelming majority of recirculated water, 34 are plate-fin energy recovery heat exchanger spray section water distribution.This part water yield is smaller, and the vertical wet channel of the wetting heat exchanger 11 of energy gets final product.1 is the air intake of this high-efficiency cooling tower, just enter the air of the horizontal dry passage of heat exchanger, 2 enter the air of spray section for leaving the horizontal dry passage of heat exchanger, 3 for leaving the air that spray section enters the vertical wet channel of heat exchanger, 4 is the air draft of this high-efficiency cooling tower, just leaves the air of the vertical wet channel of heat exchanger.51 and 52 are respectively the cooling water of expression from spray section and heat exchanger inflow water tank, and wherein the water 51 that flows out from spray section accounts for the overwhelming majority.
Figure two is the axle side schematic diagram of high-efficient low-temp cooling tower of the present invention.
Figure three is the axle side schematic diagram of plate-fin energy recovery heat exchanger 11, and 21 is vertical wet channel, forms with vertical support 24 by dull and stereotyped 23, and 22 is horizontal dry passage, is made up of flat board 23 and horizontal support 25.
Figure two, figure three schematic diagrames are for the energy sake of clarity, and several passages of only having drawn heat exchanger come out, and material object should be made up of a lot of horizontal channels and vertical passageway.
The specific embodiment:
Embodiment one: shown in figure one, figure two, figure three, the horizontal dry passage 22 that fresh air 1 at first enters heat exchanger 11 enters recirculated water spray section 12 then, then come out, return heat exchanger, and enter the vertical wet channel 21 of heat exchanger from the below of heat exchanger from the below of spray section.In this process, the fresh air 1 that enters heat exchanger 11 at first carries out heat exchange with the air draft of cooling tower and is pre-chilled to air 2, the dry-bulb temperature and the wet-bulb temperature of its air 2 all have been lowered, just the heat exchange fiducial temperature of air and recirculated water has reduced in the cooling tower spray section, and the recirculated water of processing will be lower than the temperature of the recirculated water of traditional cooling tower processing.This high-efficient low-temp cooling tower can provide temperature lower cooling water for the industry cooling, when using in the water cooled refrigeration unit, will improve the refrigerating efficiency of refrigeration unit, thereby energy consumption is just few more.Can directly use in the air-conditioning system in the time of should using in dry area provides cold water to use as fan coil or air-conditioning unit.
