Description
Technical field
The utility model relates to smoke detection and electrostatic precipitation field, relates in particular to a kind of automation and detects in real time dust arrester.

Put in the market independently smokescope and detect dress, also have can hand switch electrostatic precipitator, but do not have a kind of perfect automation to detect in real time dust arrester.We are inspired by it below, and smokescope checkout gear (containing alarm) and the two unification organising of electrostatic precipitator are combined, and have been combined into a kind of real-time detection dust arrester of automation.
One. smokescope detects, warning system:
The xenon light modulation that first generation utmost point early-stage smog alarm adopts is as probe source, and advantage is to can be observed volume various particles from small to large, high sensitivity, and the simple gentle flow monitoring of programming is positioned at detection cavity; Shortcoming is that maintenance cost is high, needs regularly xenon lamp to be changed to (detector trimming), every two years changes a filter (can reduce the susceptibility of detector), and expensive.
The infrared laser device that second generation utmost point early-stage smog alarm adopts is as probe source, and advantage is lower maintenance cost, do not need detector to rebuild, and lower cost, the range of sensitivity widely, volume is less; Shortcoming is that the detectivity of molecule is poor, still need every two years to change filter (in common region), requirement has computer and specific software to programme, air-flow monitoring be positioned at detector inlet manifold content make the monitoring capacity of detector internal gas flow poor.But often the adjustability of this smokescope detector is also bad, detector sensitivity is general non-adjustable only finely tunes in other words within a very little scope, cannot adapt to changeable environment, and the universal development space of product is less.
Short wavelength's blue light that third generation utmost point early-stage smog alarm adopts is as probe source, can be observed volume various particles (budding period detection faster) from small to large, dust and water vapour and combustion product can be made a distinction, improve air-flow monitoring and simple programming, need to be by specialist tools.But also there is no in the market a kind of smokescope detector that can monitor in real time flue gas concentration of maturation, can realize the concentration of current environment smog is carried out to real-time monitoring and feedback, the practicality of product is had a greatly reduced quality.
