Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, this adjustable negative-pressure system based on hardware structure comprise:
Air exhausting device 11: adopt engineering truck direct current evaporation fan, power 150W/24V, exhaust air rate >=800m3/h.
Defecator 3: adopt biological antibiotic drainage screen, adopts four drainage screens to form, and strengthens the rate of filtration and sterilization contact area.Defecator requires to reach for more than 99.95% (meeting national health industry standard 99.7%) to the air filtration of particle diameter 0.3 micron, requires that filtering traffic reaches more than 700m3/h; Sterilizing unit requires to reach more than 20g/h.
Sterilizing unit 2: adopt ultraviolet disinfection lamp, power 16W/220V, for independently controlling opening device according to demand.Germicidal lamp is independent circuits, needs to open corresponding equipment and function according to difference.
Instrument is equipped: adopt two cover Displaying Meters, the force value table of a set of relative atmospheric pressure reduction for checking display work medical chamber and car external environment, the Resistance Value table of a set of impedance value difference for the drainage screen import and export in display negative pressure system defecator, intuitively makes corresponding operation to facilitate.Often cover table has two detection mouths, and it is that work chamber internal pressure detects mouth that force value table detects mouth 1, and it is that work chamber external environment condition detects mouth that force value detects mouth 2, and during normal open system, pressure difference value is 10Pa to 30Pa.It is detect mouth before filtration devices that Resistance Value table detects mouth 1, and Resistance Value table detects mouth 2 for detecting mouth after filtration devices, and this table is filtration devices net power-assisted value, normal value >=60.
ON-OFF control circuit: circuit system is five circuit inserting three gear control operation blower fan speed changes realizations, and described ON-OFF control circuit comprises blower fan speed change control circuit, and for carrying out gear adjustment to blower fan in described air exhausting device, described gear is that three gears are adjustable.Certainly can understand, three gear adjustments here for keep off adjustment, specifically can arrange as required.
As described in Figure 4, for the control circuit of this circuit, these adjustable three gear speed Control blower fans, by resistance R1, R2, the difference of R3 carries out blast velocity control, the 12V DC control circuit of direct current evaporation fan, the 12V exported by vehicle-mounted inverter (1500W) exchanges, three branch lines entering direct current generator are controlled respectively through five rotary switches inserting three gears, direct current generator is carried out speed change by respective resistance R1, R2, R3 by every branch line, to meet motor speed control overflow, for system meets the requirement that difference requires environment for use.Exhaust air rate: 800m3/h-1000m3/h, can make work chamber inside form the pressure differential-10Pa to-30Pa of opposite outer environment to reach the requirement of national health industry standard;
106 negative pressure equipment antinose-dive legs: casing has corresponding import and export, access panel, instrument fixation kit etc., adopt the material of fire proofing material and the stainless steel meeting health industry standard-required to form.
As shown in figures 2 and 5, be adjustable negative-pressure System Working Principle flow chart: adjustable negative-pressure system is mounted in a set of autonomous system equipment of special vehicle work chamber inside, equipment box has independent exhaustion mouth to connect outside work chamber.During negative pressure system work, produce powerful pump drainage tolerance by the direct current evaporation fan work in the negative pressure equipment case sealed, the shutter air inlet of the contaminated air in work chamber on negative pressure equipment casing is made to enter upper strata in casing, sterilized by sterilizing unit, and enter casing lower floor by filtration devices, be pumped to outside work chamber by the air vent of blower fan by casing.
As shown in Figure 3, the ambulance with above-mentioned adjustable negative pressure system that a kind of embodiment provides is given.Specify according to national health industry standard (WS/T292-2008), protection ambulance requires band negative pressure system, for ambulance when carrying out having infection patient to transport, a set of a set of technological system that can safety concentrated to drain work medical chamber internal contamination air of unlatching; This system has can make medical chamber and external environment condition produce atmospheric pressure vacuum effect, the leakage of preventing pollution air, and concentrate take away, filter sterilization, makes medical chamber reach ventilation, object free from environmental pollution again.This standard-required negative pressure system can make work chamber inside form the pressure differential-10Pa of opposite outer environment to-30Pa, requires to reach 99.7% to the air filtration of particle diameter 0.3 micron.
Direct current evaporation fan in native system is 12V, 100Pa work is lower can reach the requirement that maximum pump discharge is 450m3/h, the air of the work chamber of standard ambulance type (about 7 cubic metres) can be made to carry out the ventilation of more than 30 times per hour, and system can realize-20Pa negative pressure working environment for ambulance in normal operation.
For the special vehicle of environmental monitoring sampling, work chamber can open system allow work realize-30Pa negative pressure working environment when detecting some chemical substances, can rapid aeration; When general ,-10Pa negative pressure working environment can allow work chamber with fresh air, and on-board crew is more comfortable, and such as: the communication for command vehicle of public security system, each Instrumental equipment is more, and caloric value is many, and work chamber needs often ventilation.
The foregoing is only embodiments of the invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
