Background technology:
Combing process its humiture in whole cotton spinning engineering requires the highest, and is the most responsive to the variation of humiture, careless slightlyly promptly can production be affected, and when serious, all boards can't be driven.
The utility model content:
The purpose of the utility model provides a kind of combing air-conditioning secondary return air use device, and it can directly discharge outdoor; Can directly send into the workshop through total air channel; Can part reuse, partly discharge.
In order to solve the existing problem of background technology; The utility model is to adopt following technical scheme: it comprises air-conditioning air delivery duct 1, combing dedusting air-return duct 3; Air channel 2 and control valve 4 in the middle of it also comprises; Air channel 2 in the middle of being connected with between air-conditioning air delivery duct 1, the combing dedusting air-return duct 3, and junction one side of middle air channel 2 and combing dedusting air-return duct 3 is provided with control valve 4.
The principle of the utility model is: in former combing dedusting return air duct appropriate location; Install a galvanized iron sheet pipeline additional; And install a control valve additional in this position, combing dedusting return air is sent into top air-conditioning air delivery duct 1 by actual needs, thereby realize combing dedusting return air is directly sent into the workshop.Play good energy-saving effect through improved air-conditioning system, brought very big facility and accuracy for simultaneously the adjusting of combing air-conditioning, do not occurred the situation that once life is rough does after the transformation.Air-conditioning primary retirn air, outdoor wind, part dedusting return air be through spray (well water direct-furnish water) once, and then mix with most of dedusting return air (title secondary return air) and to send into the workshop, be dry or the humidification effect all more stable than additive method, more can reach requirement.
The utility model can directly be discharged outdoor; Can directly send into the workshop through total air channel; Can part reuse, partly discharge.
Description of drawings:
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the system construction drawing of embodiment.
The specific embodiment:
With reference to Fig. 1; This specific embodiment adopts following technical scheme: it comprises air-conditioning air delivery duct 1, combing dedusting air-return duct 3; Air channel 2 and control valve 4 in the middle of it also comprises; Air channel 2 in the middle of being connected with between air-conditioning air delivery duct 1, the combing dedusting air-return duct 3, and junction one side of middle air channel 2 and combing dedusting air-return duct 3 is provided with control valve 4.
The principle of this specific embodiment is: in former combing dedusting return air duct appropriate location; Install a galvanized iron sheet pipeline additional; And install a control valve additional in this position; Combing dedusting return air is sent into top air-conditioning air delivery duct 1 by actual needs, thereby realize combing dedusting return air is directly sent into the workshop.Play good energy-saving effect through improved air-conditioning system, brought very big facility and accuracy for simultaneously the adjusting of combing air-conditioning, do not occurred the situation that once life is rough does after the transformation.Air-conditioning primary retirn air, outdoor wind, part dedusting return air be through spray (well water direct-furnish water) once, and then mix with most of dedusting return air (title secondary return air) and to send into the workshop, be dry or the humidification effect all more stable than additive method, more can reach requirement.
This specific embodiment can directly be discharged outdoor; Can directly send into the workshop through total air channel; Can part reuse, partly discharge.
Embodiment:
According to the utility model air-conditioning system is transformed, according to general theory, dust pelletizing system is the 15KW centrifugal blower, and exhaust air rate is 22000-27000m
3/ h, air-conditioning air output then should be greater than its exhaust air rates, and breeze fan should select the above axial flow blower of 15KW could guarantee that air output reaches requirement at least.Adopt the scheme of Fig. 2 to need only 4KW axial flow blower, blower fan frequency 20HZ, about 10000m
3/ h air quantity just can satisfy production needs (outdoor wind+air-conditioning return air=4KW axial flow blower air output), and its total air output is: outdoor wind 8000m
3/ h+ air-conditioning return air 2000m
3/ h+ dedusting return air 5000m
3/ h+ secondary return air 22000m
3/ h=37000m
3/ h is greater than exhaust air rate 27000m
3/ h, and played energy-saving and cost-reducing effect.
Can find out by Fig. 2; Air-conditioning primary retirn air, outdoor wind, part dedusting return air are through once spraying (well water direct-furnish water); And then mix with most of dedusting return air (title secondary return air) and to send into the workshop; Be dry or the humidification effect all more stable than additive method, more can reach requirement, it is more stable that enthalpy changes.
Relative humidity is analyzed:
Outdoor wind: T does=29 ℃, wet=28 ℃ of T, and relative humidity Rh=91%,
Return air: T returns=and 29.5 ℃, wet=25 ℃ of T, relative wet temperature Rh=64%,
Mix back: T and do=29 ℃; T wets=25 ℃ (the outdoor wind of minute quantity), and relative humidity Rh=75% uses little air quantity well water (18 ℃ of water temperatures) spray to handle 23 ℃ of back dew-point temperatures; Relative humidity Rh=95% with send into the workshop after secondary return air mixes through heat up (waiting wet heating); Temperature is 29.5 ℃, relative humidity Rh=64%
Water capacity changes: outdoor wind water capacity T does wet=28 ℃ of d=24g/Kg dry air of=29 ℃ of T d=16g/Kg dry air behind the little air quantity well water spray of mix wind, before handling, lacks the 8g/Kg dry air.
In sum, through a large amount of use dedusting secondary return airs, a small amount of side wall return air and the new wind of minute quantity; Guarantee that the workshop is in slight positive pressure state; Under inclement weather conditions,, effect (50 meters well water a bites of faint low-temperature receiver have been brought into play best through little air quantity circulation processings of drying; 25-30 cubic meter per hour), satisfied the production demand.
It is following to transform back combing air-conditioning adjusting energy-saving analysis:
Air-conditioning should be joined one of 15KW axial flow blower in theory, joins 2 of dehumidifiers simultaneously and dries to heat, and dehumidifier is almost removed in the former 4/8KW motor 20Hz operation of actual use from.
Energy-saving analysis:
Blower fan: 15KW * 8400h * 75%-4KW * 8400h * 75% * (20 ÷ 50) 3=92887KWh
Dehumidifier: 7 months (1,2,3,6,7,8, September) is opened in 20 days, every year, per hour the about 10KW of power consumption calculates according to opening in one month for 2 dehumidifiers,
10KW·h×24×7×20＝33600KW·h
The about 92887+33600=126487KWh of annual total economize on electricity
Therefore; The utlity model has following promotional value: can promote in full company combing air conditioning chamber,, change into and use the 30KW blower fan with existing 55KW, 45KW blower fan; Converting operation; Can economize on electricity every year hundreds of thousands even unit up to a million, it is more accurate that air-conditioning is regulated, and workshop moisture temperature is more stable.
