The specific embodiment
Be further described the present invention is novel below in conjunction with drawings and Examples.
As shown in Figure 1, the intelligent through-flow air exchange system is housed in the underground parking garage.Smoke exhaust fan 4 and air draft blower fan 5 wherein are housed in the machine room of underground parking garage 1, the through-flow air-changing device 2 of some is installed on the warp of the road of car park and ramp natural wind 6 processes, elements such as polluter receptor 10, cyclelog 7, electromagnetic contactor 8, transformer 9 are housed in the cabinet of through-flow air-changing device 2, are integrated into intelligent through-flow ventilator.
As shown in Figure 2, cyclelog 7 input/output terminals join with the inductive probe input and output of polluter receptor 10 respectively, other one group of signal output part and electromagnetic contactor 8 inputs join, cyclelog 7 power supply imports connect transformer 9, transformer 9 input termination 220V power supplys, the power input of 8 two outputs of electromagnetic contactor and through-flow air-changing device 2 joins, power supply import termination 220V power supply.Wherein, cyclelog 7 can provide manual mode, automatic mode, timing mode, various control patterns such as combination application mode.
Have in the same ventilation district Centralized Controller 3 is installed on the through-flow air-changing device 2, be used for unified focus control mode and the parameter of adjusting all through-flow air-changing devices.
Because the generation of many occasion harmful substances is more concentrated, can produce harm to the personnel or the article of region, but the total amount of harmful substance is with respect to the ratio in whole space very little again.Can adopt that a kind of to utilize pernicious gas to take place earlier more concentrated this moment, total amount accounts for the low characteristics of whole space proportion, utilize near the through-flow air-changing device of pernicious gas generation area that harmful substance and its ambient air are mixed, reduce the concentration of harmful substance fast, make the concentration of pernicious gas in the whole zone be lower than the permissible value that relevant department stipulates in its region.
Carrying out along with said process, concentration of narmful substance in the whole zone can rise gradually, harmful gas concentration in whole zone is during near the regulation permissible value of relevant department, open all through-flow air-changing devices in the whole space again, ventilation is carried out in whole space, pernicious gas is drained into outside the space.
The ventilation of concrete application intelligent through-flow is that the method that device is taken a breath is: at first set pollutant concentration through-flow air-changing device 2 unlatching values, through-flow air-changing device 2 is opened when polluter reaches setting value, 2 pairs of polluters of through-flow air-changing device dispel dilution, when pollutant concentration falls after rise to setting value, after time-delay a period of time, through-flow air-changing device is closed; If the pollutant concentration of intelligent through-flow ventilator 2 impressions does not fall the setting value of closing to through-flow air-changing device 2 after rise in the certain hour section, this intelligent through-flow ventilator 2 reaches signal the Centralized Controller 3 of through-flow air-changing device 2 systems by netting twine 13; Centralized Controller 3 utilizes the netting twine 13 that connects all through-flow air-changing devices 2 signal to be reached again the cyclelog 7 of all through-flow air-changing devices 2, cyclelog 7 is opened through-flow air-changing device 2 polluter is blown to concentrated exhaust outlet 12, Centralized Controller 3 utilizes one group of holding wire that air draft blower fan 5 is opened again, the polluter of exhaust outlet is drained into outdoor, all through-flow air-changing devices 2 and and exhaust blower 5 operation certain hours after close.
Intelligent through-flow ventilator 2 is by polluter receptor 10 and cyclelog 7 switch voluntarily.When the pollutant concentration that senses when any intelligent through-flow ventilator 2 surpasses setting value (the maximum acceptable concentration 80ppm of polluter in garage), intelligent through-flow ventilator 2 is opened pollutant is dispelled, make it to be lower than setting value (polluter safe level 30ppm), this moment, the intelligent through-flow ventilator 2 and the blowing and discharging fan 5 of other positions were not worked.
When the pollutant concentration that senses when any intelligent through-flow ventilator 2 surpasses setting value (80ppm), intelligent through-flow ventilator 2 is opened, but pollutant concentration can't be reduced to below the setting value (30ppm) between certain, the pollutant concentration that whole ventilation space is described is higher, can't realize polluter is continued to dispel the effect of dilution; This moment, whole ventilation system was started working, and reduced to setting value (30ppm) in pollutant concentration and quit work after following 600 seconds.
At through-flow air-changing device air intake reload temperature receptor 14, at temperature exceeding standard or when unexpected temperature rise is arranged, thermoreceptor 14 can reach signal in the central controller 3, cuts off all at the power supply of the through-flow air-changing device that moves by central controller 3, carries out automatic control state again behind the time-delay certain hour.
According to different service conditions polluter maximum acceptable concentration in the garage is set; Pollutant concentration low spot in the garage; Adjust the ventilation blower fan pollutant concentration is reduced to the following delay working time of setting value.
