A kind of flue gas online detection instrument
Technical field
This utility model relates to biomass boiler technical field, is specially a kind of flue gas online detection instrument.
Background technology
Biomass fuel refers to burn as fuel biological material, and the most mainly agriculture and forestry organic waste material is (such as straw, saw
End, bagasse, rice chaff etc.), the main distinction is in Fossil fuel.In current national policy and environmental protection standard, life of directly burning
Material belongs to high pollution fuel, only uses in the brick kitchen range in rural area, uses not in city.The application of biomass fuel,
Actual mainly biomass molding fuel (BiomassMouldingFuel is called for short " BMF "), is as former material using agricultural refuse
Material, through pulverizing, mix, extruding, the technique such as drying, makes various molding (such as bulk, graininess etc.), can directly burn
A kind of Novel clean-fuel.
With biomass energy as the boiler of fuel biomass boiler, it is divided into biomass steam boiler, biomass hot water
Boiler, biomass thermal wind furnace, biomass heat-conduction oil oven, vertical type biomass boiler, horizontal biomass boiler etc., at biomass boiler
Before dispatching from the factory, will detect through a series of combustion product gases, owing to the detection time is longer, traditional detecting instrument lacks online prison
The measure of pipe, ageing not strong, have much room for improvement.

Net.
As this utility model further technical scheme, described remote terminal is mobile phone, panel computer or PC
People's computer, described mobile terminal is mobile phone or panel computer.
As this utility model further technical scheme, described filtration couveuse include casing, adsorbing powder dust layer,
Thermostatic heater, thermostatic heater is fixed on the bottom of casing, and adsorbing powder dust layer is arranged in casing.
As this utility model further technical scheme, process tank is a container sealed, and is full of at least in it
Treatment fluid more than one half volume.
Compared with prior art, the gas that when this utility model uses, staff can detect with real-time reception detector
Sample information, finds in time when there are abnormal conditions, conveniently analyzes, finds out reason, improves the ex factory pass rate of boiler.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of flue gas online detection instrument.
Fig. 2 is the structural representation of PLC in this utility model.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1~2, a kind of flue gas online detection instrument, including gas collecting device, filter couveuse 5, detector
7, PLC real-time controller 9 and process tank 6, the outfan of gas collecting device and the input filtering couveuse 5 are led to by unidirectional
Road 4 connects, and the outfan filtering couveuse 5 is connected by half-duplex channel 4 with detector 7, the flue gas output of detector 7 and place
Reason tank 6 connects, and the control end of detector 7 is connected with PLC real-time controller 9, and PLC real-time controller 9 includes a main control unit, institute
The main control unit stated is by central processing module, analog input and output module, digital quantity input/output module, data memory module
Forming with network communication module, main control unit is PLC or single-chip microcomputer, and PLC is preferably Micro830, and single-chip microcomputer is preferably ARM9,
Main control unit passes through WLAN, and using ICP/IP protocol or other communications protocol to connect has wireless router, wireless routing
Being connected to maintenance remote terminal and control mobile terminal on device, described remote terminal is mobile phone, panel computer
Or PC PC, described mobile terminal is mobile phone or panel computer, and main control unit is also associated with display screen and alarm.
During work, mobile phone, panel computer and the PC PC as remote terminal and the mobile phone as mobile terminal and
Panel computer is fitted with APP software, and by utilizing WLAN to be connected with wireless router, control unit is by arranging it
Interior network communication module is also connected with wireless router;The mobile phone of mobile terminal and panel computer can also be directly by controlling
Network communication module in unit is connected with control unit, and by arrangement above, user of service can examine with real-time reception detector 7
The gas sample information measured, finds in time when there are abnormal conditions, conveniently analyzes, finds out reason, improves dispatching from the factory of boiler
Qualification rate.
Harvester includes horn-like collection bucket 1, air pump 2, and air pump 2 is arranged on bottom horn-like collection bucket 1, at loudspeaker
Fix one in shape collection bucket 1 and cover the horn-like dust-filtering net 2 gathering bucket 1 cross section, described filtration insulation case and bag
Including casing 5, adsorbing powder dust layer 51, thermostatic heater 52, thermostatic heater 52 is fixed on the bottom of casing 5, carries out in casing 5
The heating of constant temperature keeps temperature, and adsorbing powder dust layer 51 is arranged in casing 5, and process tank 6 is a container sealed, and is full of in it
Treatment fluid more than at least one half volume.
Gathering gas when, horn-like collection bucket carries out filtering, by drainage screen, by dust-filtering, so for the first time
Rear entrance filters couveuse, in filtering couveuse, is further processed dust, it is common practice to keep constant temperature, logical
Cross precipitation, dust thoroughly removed, and thermostatic heater is possible to prevent condensation to occur, thus ensure the degree of accuracy of gas test,
The gas finally detected enters in process tank, processes, and prevents from polluting and makees the better embodiment of this patent above
Describe in detail, but this patent is not limited to above-mentioned embodiment, the knowledge model that one skilled in the relevant art is possessed
