Description
Technical field
The present invention relates to stove flue gas detection technique field, relate in particular to a kind of stove flue gas detection system based on radio sensing network.
Background technology
Materials such as the particle in the stove flue gas, sulfide, bioxin are quite extensive to the harm of air quality, and have the advantages that to be difficult to centralized detecting and comprehensive assessment.Traditional stove tail gas detection system is to detect certain specific material, owing to be limited by specific (special) requirements such as checkout equipment installation, power supply, checkout equipment is design and installation when engineering construction usually, in case detecting index and detection method changes, usually need be to the transformation of stopping work of original stove, influence produce and cost higher.
Tradition stove flue gas detection system is the part of stove production control system, stove flue gas testing result is a feedback input of stove production control normally, when harmful substance is not up to standard in the stove flue gas, do not allow to discharge and proceed circularly purifying and handle, till the flue gas harmful substance contents is up to standard.With the advantage of the integrated flue gas detection system of production control system be to feed back input, circularly purifying, the system availability height, but handle because this system need suck flue gas not up to standard again, this detection system is common not in the position of fume emission point, but is positioned at before the direct emission point, therefore testing result is not the data of direct emission point, because this system is that factory or enterprise build voluntarily, its data do not possess objectivity, can not be as the sampled data of supervision units such as Environmental Protection Agency.
Stove flue gas detection technique is the high-tech technology that development in recent years is got up, the stove flue gas detects for administering air pollution very necessary, set up detection and the warning system of stove flue gas and can in time find the source of atmospheric pollution, find potential pollution source by assessment, avoid the expansion of polluting.Owing to contain the multiple material that causes air pollution in the stove flue gas, the pollutant component proportional difference of different stoves is bigger, be difficult to calculate the comprehensive pollution indexes of stove flue gas, standard GB 9078-1996 " industrial furnace atmosphere pollutants emission standards " has stipulated the concentration maximum of various materials permission dischargings in the stove flue gas, but, combination less than the various materials of discharge standard also may bring serious pollution, and the result who this combination is carried out comprehensive assessment more can react actual pollution condition.China recent years has some units to begin to carry out pollution comprehensive assessment work gradually, but normally to the assessment of a certain regional water quality, air, soil, noise etc., some units are also arranged at stove smoke pollution comprehensive detection and assessment, but also have following a series of problems in actual the use.
Use the stove flue gas detection system of bus-type, need analyze the room in the construction of stove emission point annex, and the power supply of checkout equipment and signal transmission all need special wiring.The shortcoming of this mode is that the installing engineering amount is big, and on-the-spot the needs laid special cable, needs time-based maintenance and maintenance.Particularly some adopt the stove of smoke stack emission, highly generally surpass 15 meters, and maintenance and maintenance work cost are higher.And stove is widely distributed, adopts to analyze to transfer data to mode data objectivity and the real-time deficiency of supervising unit after industrial computer analysis and transmission data are installed in the room.
Use a plurality of detection systems to obtain smoke pollution material content data, the sample frequency of each detection system, accuracy, transmission means there are differences, and the major defect of this mode is system's repeated construction waste investment, and the comprehensive assessment data are insufficient.
