The specific embodiment
Following examples are used for the present invention is described, but are not used for limiting the scope of the invention.The present embodiment sour corrosion gas purifier used and sorbing material used thereof are provided by Beijing Tongfang Purification Technology Co., Ltd..The present embodiment all the other equipment used and device, be all and meet commercial the obtaining that production safety requires.
Embodiment 1 filters acid etchant gas air feed pattern
confined space 13 is in the sour corrosion gaseous environment, while needing superpressure to ventilate, from hand behaviour's plate 19 or the touch-screen 20 of control centre 12, send instruction, through main frame 11, by control box 10, open this kind air vent mode, the air that contains sour corrosion gas in environment is entered by blower fan 1 at this moment, through air intake electric T-shaped valve 2, enter sour corrosion gas filter system 3, in this adsorption filtration through column type adsorption filtration part 18, purify, air after purification is through air-supply electric T-shaped valve 4, enter indoor apparatus of air conditioner 6, cold/heat of being supplied with by off-premises station 5 is herein regulated, reach the temperature of setting, after humidity, enter confined space 13, at confined space 13, by superpressure sensor 9, the superpressure signal is uploaded to control centre 12 through control box 10 and main frame 11, and also upload to touch-screen 20 by the air quantity that the air flow sensor 9 of blower fan 1 is measured, show in the lump, by after control centre's 12 judgements, sending instruction, open leak informaton valve 7 and blower fan 1 intake simultaneously, and control opening degree, the processing of leaking informaton, can guarantee the safe ventilation demand of confined space in the sour corrosion gaseous environment thus.
Confined space 13 is in these type of sour corrosion gaseous environments such as acid mist that sulfuric acid, hydrochloric acid, nitric acid forms and hydrogen sulfide, chlorine, sulfur dioxide, hydrogen chloride, nitrogen oxide, when the sour corrosion gas concentration is 2000ppm, can remain superpressure air intake mode 3 more than 0 minute, but the longest must not be over 60 minutes; When the sour corrosion gas concentration is 1000ppm, can remain superpressure air intake pattern more than 60 minutes, but the longest must not be over 90 minutes; When the sour corrosion gas concentration is 500ppm, can remain superpressure air intake pattern more than 120 minutes, but the longest must not be over 180 minutes.
The clean air feed pattern of embodiment 2
clean ventilation is that confined space 13 environment of living in was when both no acidic etchant gas was also without other pollutants, while needing to form the superpressure ventilation, from hand behaviour's plate 19 or the touch-screen 20 of control centre 12, send instruction, through main frame 11, by control box 10, open this kind air vent mode, air in environment is entered by blower fan 1 at this moment, after air intake electric T-shaped valve 2 without sour corrosion gas filter system 3, directly through air-supply electric T-shaped valve 4, enter indoor apparatus of air conditioner 6, cold/heat of being supplied with by off-premises station 5 is herein regulated, reach the temperature of setting, after humidity, enter confined space 13, at confined space 13, by superpressure sensor 9, the superpressure signal is uploaded to control centre 12 through control box 10 and main frame 11, by after control centre's 12 judgements, sending instruction, open the valve 7 that leaks informaton, and control opening degree, the processing of leaking informaton, can guarantee the safe ventilation demand of confined space in cleaning ambient thus.
Confined space 13 is under clean air feed mode state, and ventilation time is not subjected to time restriction.
Embodiment 3 is isolated from the oxygen supply pattern
Isolated ventilation is that confined space 13 is at a kind of confined space Protection that filters under the state that etchant gas ventilates and/or clean ventilation all lost efficacy; Be under this kind duty, from control centre 12, send the isolated ventilation instruction, through main frame 11, by control box 10, open this kind air vent modes, air intake triple valve 2, air-supply triple valve 4, leak informaton valve 7 and air intake blower fan all are in closed condition, and confined space is air intake, also outwards air draft neither; At this moment, the wind in confined space 13 can only enter indoor apparatus of air conditioner 6, and cold/heat of being supplied with by off-premises station 5 is herein regulated, and enters confined space 13 after reaching the temperature, humidity of setting.
While carrying out isolated ventilation, need to open the self oxygen system 21 in confined space 13, so that confined space 13 forms superpressure, by the more than 30 minutes of must not hold time in the sour corrosion gaseous environment, and need rapidly confined space be turned and withdraw to safety zone.
Instantiation of the present invention; confined space security protection and control system in sour corrosion gaseous environment of the present invention are illustrated and describe; but on basis of the present invention; the technical staff should be understood that; the modification that it is made and improvement; the spirit that limits if do not departed from the claims in the present invention book, all belong to the scope of protection of present invention.
