Regulation covers the extraneous gas flow of room machine, that is, fills into the rotating speed of benefit blower fan 702 of air.Extraneous air, which is diluted, to be stirred
Mix, reach and mixing air after dilution is discharged into interior after relevant national standard.
The setting of air return branch 8, the high temperature pure air after part purification is intercepted, add to three-level purification upstream
Section, and the ozone air to be clean with the three-level of organic matter, organic volatile mixs, and raising three-level purifies upstream and measures Air Temperature
Degree and gas flow rate pressure, make temperature, blast while the high efficiency range for meeting catalyst, and reduce the nickel chromium triangle of three-stage filtration section 6 and add
The energy consumption of heat supply network 601, the power consumption of machine is reduced, reach the purpose of cleaning, energy-saving.
The setting of temperature and blast probe, the temperature and blast of monitoring three-level purification upstream air, when temperature is less than catalysis
Agent electric heating high efficient district, the temperature of nickel chromium triangle heating net 601 and the flow of secondary use recovery hot-air, three-level mistake can be adjusted simultaneously
Filter section 6 air to be filtered reaches the high efficient district of catalyst；Purification efficiency is improved, and reduces the energy consumption of heating plate；When blast does not have
When having catalytic effect optimal in catalyst, the wind speed of the backflow blower fan 802 in adjustment air return branch 8.
The present invention specific filter process be：By-pass filtration section 4 filters the miscellaneous of bulky grain thing and more than pm2.5 in flue gas
Matter, bacterium, particulate matter.The superfine particulate matter particulate matter and organic volatile for being below pm2.5 after by-pass filtration, in flue gas
(aldehyde material, aldehydes matter).At this moment flue gas enters secondary filtration section 5 with pipeline interior air-flow.Net occurs through anion
501, carry into a large amount of anions in flue gas.
Anion is mixed with superfine particulate matter and organic matter, the volatile matter of flue gas, and coalescence is into relatively large organic
Thing micel and particulate matter group.Because anion can make oxygen be transformed into ozone, therefore the flue gas of secondary filtration section 5 contains necessarily
The ozone of amount.The flue gas of secondary filtration section 5 is through during foam metal filter 502, and electronics is by foam metal filter
Ground wire of the 502 electric conductivity backward walking to power supply.The flue gas of anion is lost by the densification of foam metal filter 502
Passage meeting wall hanging is practically free of particulate matter inside foam metal by flue gas derived from foam metal filter 502.Only one
Quantitative ozone, a small amount of organic matter and organic volatile (formaldehyde, phenol etc.).Contain a certain amount of ozone, organic matter and organic
The flue gas of volatile matter is first passed around by nickel chromium triangle heating net 601, heating flue gas to 150 degrees centigrades, i.e. catalyst high efficient district
Temperature range, then by scribbling Pt/Pd as 4:The cordierite of 1 catalyst keeps away fluid layer 602, and cordierite keeps away the highly dense of fluid layer 602
Degree can almost remove all flue gas particles, the organic matter of macromolecular；Organic matter, aldehydes organic volatile can be warm herein
Spend, fully reflected with ozone by catalyst under Action of Wind pressure, generate C02 and H2O, the opposite side of fluid layer 602 is kept away from cordierite
Filter out.The three-stage filtration section 6 of the present invention is mainly catalytic oxidation-reduction reaction, and suitable blast and temperature can make catalyst height
Effect catalysis；For the air concentration of pollutant 10~55%, catalyst reaches 60- in 150 degree or so of temperature to its conversion ratio
90%.In order to maintain the high efficient district of catalyst to run, temperature and blast probe are placed in section nickel chromium triangle heating net 601 and violet green grass or young crops by us
Stone keeps away the intermediate cross-section geometric center position of fluid layer 602, is the steady layer of air current composition, probe gas main flow temperature parameter and wind
Parameter is pressed, and temperature and wind pressure parameter are reached into controller, temperature and wind during optimal according to the catalyst catalytic effect of controller
Press and contrasted with the temperature of reality and blast, and adjust nickel chromium triangle heating net 601 and backflow blower fan 802 in real time and run power, adjust
Save the actual temperature in the front end of three-stage filtration section 6 and blast；Test is kept away in the case where meeting catalysis gas work barotropic condition according to cordierite
The relation of the thickness of fluid layer 602, area and windage, the malleation of optimum efficiency of catalyst reaction is catered to by pressure section, finds violet
Green stone keeps away the optimum thickness of fluid layer 602.Stream is kept away herein for industry, family, requirement of the public arena to air quantity, clarifier cordierite
The thickness of layer 602 will determine according to particular use.
