The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing:
Such as Fig. 1-3, a kind of spunbond melt-blowing nonwoven industrial air conditioning unit, comprise single treatment chamber 21, connecting fan chambers 12 21, single treatment chamber, fan house 12 tops arrange after-treatment chamber 22, be provided with air returning valve 1 and new air-valve 2 on the single treatment chamber 21, be disposed with thick effect filter 4, one-level surface cooler 5 and one-level water fender 6 in the single treatment chamber 21, be provided with one-level on the one-level surface cooler 5 and take over mouth 7 for connecting the chilled water control valve; Be provided with centrifugal high pressure pressure fan 10 in the fan house 12, be provided with pressure fan air-supply interface 14 and blow valve 20 on the after-treatment chamber 22, be provided with effective filter 15, secondary table cooler 17 and secondary water fender 18 in the after-treatment chamber 22, be provided with secondary on the secondary table cooler 17 and take over mouth 16 for connecting the chilled water control valve.Be provided with one-level surface cooler discharge outlet 8 on the single treatment chamber 21, be provided with secondary table cooler discharge outlet 19 on the after-treatment chamber 22.Centrifugal high pressure pressure fan 10 connects variable-frequency motor 11.All be provided with access door 3 on single treatment chamber 21, fan house 12 and the after-treatment chamber 22.
The air mixing device that is comprised of air returning valve 1 and new air-valve 2 is mainly used in air intake, thick effect filter 4 is used for air is carried out preliminary filtration, the heat sink that one-level surface cooler 5 and one-level water fender 6 form is used for first cooling, 15 pairs of air of effective filter carry out further filtration, purification, and the reducing temperature twice device that secondary table cooler 17 and secondary water fender 18 form is used for further cooling.
When using, open motor 11 and drive 10 rotations of centrifugal high pressure pressure fans, with air from air returning valve 1
Mix by a certain percentage rear the suction in the spunbond melt-blowing nonwoven air-conditioning unit with new air-valve 2, the air that air returning valve 1 enters is to take full advantage of from blow valve 20 lingering remnants of past customs out, itself or the lower air of temperature, air at first enters thick effect filter 4 and carries out filtration, purification, the air that reaches low cleanliness factor flows into one-level surface cooler 5 and once cools, air after once cooling is processed is sent into high efficiency particulate air filter 15 by centrifugal high pressure pressure fan 10 by blower fan connector 14 and is carried out smart filtration treatment, to reach the high-cleanness, high air, the high-cleanness, high air that obtains again flows into secondary table cooler 17 and carries out the secondary processing that cools, to reach the required wind pushing temperature of technique.One-level surface cooler 5 takes over mouthfuls 7 by one-level, and secondary table cooler 17 is taken over mouthfuls 16 by secondary and linked to each other with the chilled water control valve, controls the constant of wind pushing temperature to regulate chilled-water flow.Motor 11 adopts variable-frequency motor, regulates the rotating speed of centrifugal high pressure pressure fan 10 with this, controls the pressure of blowing by the rotational speed regulation of centrifugal high pressure pressure fan 10, to guarantee the constant of blast pressure.Simultaneously, because one-level surface cooler 5 and secondary table cooler 17 can produce a certain amount of condensed water at the heat exchanging process that cools, must condensed water be blocked in case take the air-conditioning unit out of by one-level water fender 6 and the secondary water fender 18 of postposition, and one-level surface cooler discharge outlet 8 and the secondary table cooler discharge outlet 19 reserved by the air-conditioning unit are respectively discharged, wherein one-level surface cooler discharge outlet 8 is in negative pressure section in air-conditioning unit structure, need to the water seal of 500mm height be installed to guarantee the discharge of condensed water in discharge outlet.The air of last high-cleanness, high and steady temperature pressure is sent into the spinning air regulator of spunbond melt-blowing nonwoven by blow valve 20, blow to from the high polymer molten thread of spinneret ejection viscous state and force cooling curing to form superfine fibre to it, and condense upon that dependence self is bonded non-weaving cloth on the lace curtaining.
The after-treatment chamber 22 that jointly is comprised of high efficiency particulate air filter 15, secondary table cooler 17, secondary table cooler water fender 18 and blow valve 20 is stacked in fan house 12 tops, the air outlet of pressure fan 10 can directly enter after-treatment chamber 22 on the one hand, save construction and expense that airduct connects, can reduce the resistance of circulation of air simultaneously; Can shorten on the other hand the length of air-conditioning unit, save the Air Conditioning Facilities construction area.
