Description
Technical field
The present invention relates to the test of clean air package performance, be specially the primary purification efficiency test of clean air package chemical pollutant and microorgranic contaminant.
Background technology
IAQ (indoor air quality) greatly affects people's quality of life, the general level of the health and work efficiency, because people spent indoor above 85% time, room air pollution causes following three kinds of illnesss: Cure of Sick Building Syndrome (SBS), with building diseases associated (BRI), number of chemical pollutant allergy (MCS).Add up according to Environmental Protection Agency (EPA); the economic loss that the U.S. causes because of indoor air quality is inferior every year is up to 40,000,000,000 dollars, China only nineteen ninety-five the economic loss that caused because of the room air pollution health risk by the willingness to pay value estimations up to 10,600,000,000 dollars.
Can be taken precautions against and administer from three aspects the architecture indoor air pollution: the burst size of pollutant be reduced in (1) source; (2) ventilation; (3) adopt air purifying process to carry out pollution control.Because purification techniques has irreplaceable effect for room that had pollution already or outdoor air pollution than serious area, therefore causes increasing concern.
In efficiency test of purification assembly, generally adopt the single flow test, as shown in Figure 1 at present.Wherein pollutant can use the quantitative generating means of pollutant directly to throw on pipeline, also can be at front end by realizing its precision than keeping of large space concentration.This structure test process in the test of carrying out an efficient is (1), adjusts pollutant generator, makes its concentration reach the air intake concentration of test request; (2), measure air intake concentration and air draft concentration; (3) calculate an efficient.
But in this measuring process, because adjusting pollutant levels, air inlet needs certain hour, approximately several hrs.During this period since ventilating system work always, therefore the adjustment period between the pollutant that produces inevitably enter tested component inside.This process causes (1), purification assembly, and especially the life test of physisorption clarifier departs under the high concentration, and departing from that more little clarifier life test produces for the physisorption amount is big more; (2), deviation appears in purification efficiency test, the process from the assembly initial state to steady state (SS) can not accurate description.Thereby test result is inaccurate in reality test, test result effectively can not be applied in the design and running management.Therefore setting up a kind of method of testing effectively accurately at purification assembly is significant.
Summary of the invention
The present invention aims to provide a kind of method of testing of primary purification efficiency of air purification component.
The present invention also provides the proving installation of above-mentioned primary purification efficiency of air purification component.
Its technical scheme is, the proving installation of primary purification efficiency of air purification component comprises the clean air package and the pollutant generator that connect successively, and the both sides of clean air package are respectively equipped with upstream valve and valve downstream constitutes test channel;
Bypass channel that is provided with bypass valve in parallel on test channel, the node of bypass channel and test channel lay respectively at upstream valve and outside valve downstream.
Described pollutant generator and the node of upstream valve upstream and between be provided with venturi valve, flowmeter and Hygrothermograph.
Preferably, be provided with the carbon adsorption filter in the downstream of the node that is positioned at the valve downstream outside.
Preferably, be provided with roughing efficiency air filter, blower fan, surface cooler, carbon adsorption filter, inorganic high efficient filtrator, humidifier and well heater in the upstream of pollutant generator.Well heater can be at least a in water heater and the electric heater.
Earlier flow and humiture value are adjusted to setting value during test, open bypass valve, close upstream valve and valve downstream; Open pollutant generator, regulate pollutant levels, after making it to reach normal concentration, close bypass valve, open upstream valve and valve downstream, begin test.
Proving installation of the present invention and method of testing, the pollutant that produces between the adjustment period of having avoided pollutant levels enters tested component inside, thereby has guaranteed purification efficiency and purified the accuracy of life test.The present invention can be used for design, operation, the test evaluation of ventilation and air conditioning system purification assembly in the fields such as health.
