Background technology
PDA(Personal Digital Assistant) be the abbreviation of palm PC, comprise bar code scanner, rfid interrogator, POS etc., PC(Personal Computer) and be the abbreviation of computer, these two all adopt abbreviation herein.
Before the present invention, what apparatus for measuring dust concentration mainly adopted is optical means, needs flue gas to be extracted into corresponding air chamber by aspiration pump, then by analyzing light by the change after flue gas, analyzes the dust concentration in flue gas.
The detection method of optical principle is mainly divided into light scattering principle and light absorption principle.The powder concentration measurement method of light scattering principle is wherein adopted to there is two large problems: one is that working sensor electric current is bigger than normal.It is higher to the required distance of service cable, apart from the oversize phenomenon that there will be loss and cannot work too greatly; Two be due to the method adopt be optical principle, explorer portion is subject to dust pollution.In use for some time, because of problems such as zero drift is serious, sensitivity decrease, need often to demarcate, increase labour intensity.And light absorption type apparatus for measuring dust concentration is only when high concentration, it is comparatively accurate namely to measure in 8 000 ~ 15 000mg/m3, and within the scope of low dust concentration, measuring accuracy is poor, and optical system vulnerable to pollution, need often to safeguard.And at the Signal transmissions analog signals adopting 4-20mA of apparatus for measuring dust concentration and tele-control system, or the serial signal of 232 and 485, be not only easily disturbed, and need to arrange cable, add maintenance and use cost. more
Utility model content
In order to solve the problem, the purpose of this utility model is to provide a kind of high precision, non-maintaining, has the apparatus for measuring dust concentration of communication function.
The utility model proposes following technical solution:
A kind of apparatus for measuring dust concentration, comprise feeler lever, insulation division, sleeve, machine box, processor, output terminal, its middle sleeve is connected with machine box, insulation division is nested in sleeve, and feeler lever is connected with the processor in machine box through insulation division, feeler lever for extend into need detection dust concentration flue in, when flue gas flows through feeler lever, feeler lever rubs, clashes into generation static charge, static charge signal is input to processor, finally by output terminal display dust concentration.
Further, processor also comprises signaling module, modulus module, and static charge is amplified through signaling module, then is converted into digital signal through modulus module, finally by output terminal display dust concentration.
Further, output terminal is liquid crystal display.
Further, processor also comprises communication module, is connected dust concentration data are transferred to client in real time by wired or wireless communication.
Further, client is PDA or PC.
Further, the cognizance code of processor is single.Guarantee that the communication of being set up by communication module and PDA or PC is unique, can not obscure with other measurement mechanisms of surrounding.
Further, be provided with in machine box button is set, for optimum configurations.
The beneficial effects of the utility model: the utility model, owing to adopting electric charge induction technology, solves and adopts the shortcomings such as the precision of optical principle is low, power consumption large, maintenance is complicated, while substantially increasing accuracy of detection, reduce operation and maintenance cost.Adopt mechanics of communication simultaneously, solve the transmission reliability problem of the data detected, reduce transmission cost simultaneously.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation after the utility model is installed, and Fig. 2 is theory diagram of the present utility model.This apparatus for measuring dust concentration can be applicable to, in the smoke discharging pipe of the factory of the discharge such as power plant, cement mill dust flue gas, carry out on-line real time monitoring to the dust concentration of discharge.When actual installation uses, as shown in Figure 1, apparatus for measuring dust concentration 2 is contained on flue 2 tube wall, this apparatus for measuring dust concentration, comprise feeler lever 21, insulation division 22, sleeve 23, machine box 24, processor 25, liquid crystal display 26, its middle sleeve 23 is connected with machine box 24, and insulation division 22 is nested in sleeve 23, and feeler lever 21 is connected with the processor in machine box 24 through insulation division 22.Feeler lever 21 for extend into need detect dust concentration flue 2 in, when flue gas flows through feeler lever 21, feeler lever 21 rubs, clashes into generation static charge, processor 25 comprises signaling module 251, modulus module 252, static charge is amplified through signaling module 251, be converted into digital signal through modulus module 252 again, show dust concentration finally by liquid crystal display 26.
Processor 25 also comprises communication module 253, is connected dust concentration data are transferred to client PDA or PC in real time by wired or wireless communication.The cognizance code of processor 25 is single, guarantees that the communication of being set up by communication module and PDA or PC is unique, can not obscure with other measurement mechanisms of surrounding.Be provided with in machine box 24 and button is set, for optimum configurations.
Dust granules at the volley phase mutual friction can produce electric charge, the quantity of electric charge of generation and the concentration of dust granules linear.Electric charge in flue gas is near feeler lever time, and can produce micro-induction current to feeler lever, the friction between dust granules and feeler lever also can produce micro-electric current, and this electric current process amplification process slightly, converts concentration values to and be output into 4 ~ 20mA signal.
Mounting points is selected in straight flue place, and apparatus installation should be avoided to turn round at flue, flue meet.And it is unsettled for ensureing that feeler lever inserts in flue, can not encounter inner support or other equipment.If possible be arranged on air flow method to put uniformly on position as far as possible, better measurement effect can be obtained.
In sum, the just a kind of preferred embodiment of the present utility model described in this instructions.All technician in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in claims of the present utility model.
