Description
Technical field
The present invention relates to laying dust and detect particularly a kind of air conduit laying dust detector, automatic laying dust detecting device and method.
Background technology
Ventilating duct with central air conditioner system is an example.The clean condition and the IAQ (indoor air quality) of central air conditioner system have important relationship.If the air-conditioning system of long-time running is cleaning and sterilizing irregularly, be collected at a large amount of grits, the germ virus in the ventilation and air conditioning system, the materials such as organism, mould and fragment that rot, in the inlet chamber, the serious threat people's is healthy with the wind; In addition, the environment of cooling tower warm moist is easy to become the hotbed that germ multiplies in the air-conditioner water system, and these malignant bacterias can be blended in the process of air-treatment among the air-supply, and in the inlet chamber, it is sick that the people is infected, for example legionaires' disease.
At the with serious pollution sanitary conditions of public place central air conditioner ventilating system, state compulsion standard GB19210-2003 requires every square meter of central air conditioner ventilation duct to pollute laying dust amount≤1 gram; The Ministry of Public Health has issued the related management way and has cleaned standard, the then necessary pipe blow-through of the every square meter laying dust of central air conditioner ventilation duct amount 〉=20 grams, minimumly every two years the pollution situation of central air conditioner ventilating system is carried out a hygiene assessment, the failure will clean.But, because China region is wide, the physical environment difference is bigger, caused central air conditioner in different external environment condition quality, different unlatching service time, different temperature and temperature, different protection filtration grade ... there is usage variance under these composite factor situations, this just needs concrete quantized data, and central air conditioner ventilating system is carried out scientific management.
The method of China's employing at present is to rely on supervision detection department, carries out pipeline tapping wiping sampling to the scene, public place that central air conditioning uses, and judges to the way of laboratory Weighing again.Concrete method of operating: the dismounting ceiling of reaching the spot, remove heat-insulation layer, open 300 * 300 millimeters mouth at duct wall with electric clippers, sampling robot is put into ventilating duct utilize dust suction or scraper plate mode that the internal contamination sediment is taken out, afterwards pipeline is recovered successively.Marine sediments encapsulate with airtight container, and it is taken back testing laboratory, with the calculating of weighing of ten thousand/electronic balance, draw the report that whether exceeds standard.This method all needs huge paying on cost of labor and time cost, in addition owing to exist the manually-operated error phenomenon that sampled result is unreasonable, error is bigger may occur.
With market, Beijing is example, according to Beijing health supervision department statistics, municipalization more than 6000 families in Beijing need the public place and the building of cleaning, to implement to pollute dynamically the laying dust monitoring if cleaning first finishes, even all health supervision personnel are engaged in a such job and are difficult to finish this work, adopt enterprise to check that voluntarily unfounded phenomenon can appear detecting again in report voluntarily.There are nearly 5,000,000 central air conditioner applying units in the whole nation according to statistics, want after cleaning first to implement to detect, its workload is big has just well imagined, problem and contradiction in the face of such needs solution, we think and must adopt new and high technology to utilize high-tech means to replace the work of artificial this heavy poor efficiency, it is accurate to make it rapid and simple science, Here it is aim of the present invention place.
