Description
Affiliated technical field
The utility model relates to a kind of probe, the general direct extraction-type probe of particularly a kind of gaseous contaminant continuous monitoring.
Background technology
The utility model is applied to the direct extraction emission source gas subsystem of stationary pollution source continuous blow-down monitoring system.It is the front device that directly extracts the emission source gas system, is installed on chimney or the flue, to the flue gas heating and filtering, can set the heating-up temperature of adjusting flue gas.
At present, known direct extraction-type sampling probe structure by coarse filter (by sintered stainless steel or porous ceramic film material make, 10～50um aperture), straight-through metal tube, flange (with the butt joint of chimney upper flange), well heater, joint (being connected the electric tracing pipe) form.Probe is installed in (coarse filter and metal tube are in chimney, and flange, well heater, joint are outside chimney) on the chimney flange, links to each other with electric tracing pipe, fine filtrator, sample gas control system treatment element, membrane pump, analyser then; When sample gas is extracted out from chimney, after heating, filter, dewater, remove SO3 etc. and handling, the body analyser of supplying gas is analyzed.Though this kind probe can satisfy request for utilization, comes with some shortcomings: 1: because coarse filter directly places in the chimney, because of the collision of particle in the flue dust with penetrate in the porosint and result in blockage, life cycle is short, is difficult to clean reuse; 2: sample gas also will cause the gas circuit resistance to increase through one-level fine filtrator (1 μ aperture) behind coarse filter; 3: when cleaning or replacing filtrator, unload whole probe, and will lay down the electric tracing pipe, very inconvenient.
Summary of the invention
This technical scheme that novel its technical matters of solution adopted is: for overcome filter blocks, clean difficulty, life cycle is short, the gas circuit resistance is big, remove and install problem such as inconvenience, the utility model provides the direct extraction-type of a kind of gaseous contaminant continuous monitoring probe, but but this sonde configuration significantly reduced obstruction, the filtrator repeated washing of filtrator use, prolonged the cleaning frequency for a long time, reduced the gas circuit resistance, very convenient and need not lay down electric tracing pipe, flue gas heating-up temperature regulated at will when changing filtrator.
Adopt welded type multilayer net stainless steel filter core, and increase the filter area of filter screen, the front end of filter core is a blind plate; Filter core links to each other with the end cover of filter cylinder is coaxial by screw thread, then end cap, filter core is screwed in filter cylinder by engage thread with coaxial direction again; Filter cylinder front end centre bit is equipped with a screw, and metal tube is linked to each other with the filter cylinder coaxial cable threadably, and filter cylinder rear end (gland bonnet end) has a joint to link to each other with the electric tracing pipe on the side; Heating collar is fixed on the external garden of filter cartridge, and encloses heat-insulation layer, heating collar is controlled by the adjustable temperature controller; Temperature controller is contained in the filter cabinet, then filter cabinet, filter assembly (filter core, end cap, cylindrical shell, metal tube, heating collar, heat-insulation layer) is linked together with mounting flange, constitutes direct extraction-type sampling probe (seeing accompanying drawing).
When flue gas aspirates at membrane pump, flow to filter cylinder through metal tube, most particle collides on the front end blind plate of filter core under the inertia effect of air-flow in the flue dust, drops in the filter cylinder, flue gas enters radial diffusion behind the filter cylinder, turn to then along tube wall and flow to filter core gradually, again by filter core, in end cover axially and radial bore flow to pipe adapter, simultaneously flue gas is heated to the temperature of setting, at last by pipe adapter to the electric tracing pipe.
This novel beneficial effect is that this kind structure has significantly reduced obstruction, the prolongation of filtrator
