Background technique
Air temperature type vaporizer is generally make of finned aluminum pipe, and when the liquid gas of " ice-cold " flows into vaporizer, vaporizer ambient air produces heat exchange with the ice-cold liquid gas in fin aluminum pipe, and temperature reduces.Thus cause the flowing of air, there is the air of new " relatively hot " to be rushed to around vaporizer and continue heat exchange.
Certainly, this is a kind of perfect condition, and in fact air temperature type vaporizer is all be made up of multiple, and be commonly called as air temperature type Vaporizing Station, air temperature type Vaporizing Station is generally arranged on outdoor, also has some Vaporizing Stations for urgent air feed to be arranged on indoor; Usually utilize wind to promote that vaporizer outside air circulates, and when cloudless, when there is no wind, also can start supplementary equipment and assist vaporizer heat exchange.
Poor for some ambient air stream, for meeting vaporizer heat exchange efficiency, the outside of each vaporizer is provided with housing, the top of housing is provided with 3-4 blower fan; When such as above-mentioned situation, when occurring that the calm or air circulation of environment comparatively occurs fog around official post vaporizer, the blower fan of housing upper can be opened, increase air circulation, thus improve vaporizer heat exchange efficiency, prevent evaporator surface frosting and surrounding environment from occurring fog simultaneously.
But Problems existing is at present: in air temperature type vaporizing station, each vaporizer fan is opened, though ensure that the heat transfer rate of each vaporizer, power consumption is large, cost is high.
Summary of the invention
For the problems of the prior art, the invention provides a kind of low in energy consumption, cost low while ensure the air temperature type Vaporizing Station of each vaporizer heat transfer rate.
In order to achieve the above object, technological scheme of the present invention is: a kind of air temperature type Vaporizing Station, comprise at least three vaporizers, comprise supporting frame, blower fan, the first airduct and the second airduct, outside described each vaporizer, case is installed, support frame as described above is arranged on the top of case, described blower fan is fixed on supporting frame, the exhaust outlet of described blower fan is connected with first airduct one end, the other end of the first airduct is communicated with case top, described second airduct is by head and the tail connection each other between at least three cases, and described case from top to bottom cross-section area diminishes gradually.
Can find out that this practical tool has the following advantages according to such scheme: when wind in the first air channel is in a case during vaporizer air blast, because case becomes under cross-section area becomes gradually from top to bottom, the vaporizer heat transfer rate in case can be ensured, when in case, air-flow enters the second airduct simultaneously, airspeed can be ensured, although now air-flow has certain weakening, but when entering next case, first airduct on this case top can continue to accelerate to this air-flow, although the power requirements of the present invention to blower fan is higher, but total consumed power is more a lot of than original each case being joined 3 to 4 Fans lower power consumption.
As improvement, described each case bottom is provided with the water outlet flowed out for liquid water; Air temperature after a upper case is lower, heat can liquefy, water outlet is set up in each second airduct bottom and can prevent vaporizer corrosion in the second airduct.
As improvement, the inwall of described first airduct, the second airduct and case is provided with rust preventive coating; Owing to adopting the design of circulation air path, make in whole system that in air, water content can be higher than air moisture content in original design, inwall is provided with rust preventive coating and can increases the service life.
As preferably, described case is inverted cone-shaped; Promote that frozen water mixed solution is discharged from water outlet.
As preferably, the cross section of described case is 1.5 ~ 2 with the ratio of down cross-sectional size; 1.5 ~ 2 can ensure that power consumption is lower.
As improvement, described air temperature type Vaporizing Station also comprises multiple heater band, and described heater band is arranged on the tube wall of the second airduct; Setting up heater band can air-flow in dry airduct, and after heating, air can reduce the frosting degree of each vaporizer simultaneously.
