Description
Technical field
The present invention relates to code probe field, be specially a kind of Novel smog number probe.
Background technology
The sampling probe that flue gas discharge continuous monitoring system adopts is that single layer filter extracts probe completely mostly.In production and use procedure, there is following technical matters and potential risk in this sampling probe: 1, the heating component system of twining is loaded down with trivial details, and single layer filter extracts probe completely and adopts electrical heating wire heating.The manual winding of heater strip, needs interval to smear high-temp glue and placing glass silk cloth insulate, and production efficiency is low, and consistance is poor, constrains raising and the reliability of probe quality; 2, heater strip easily damages, and in engineer applied, because field condition is severe, temperature control damages, and corrosive gas such as to enter at the reason, and heater strip very easily blows.It is long that probe returns company's maintenance cycle, also needs, for scene provides probe for subsequent use, to add cost of serving; There is hidden danger in sealing of 3, popping one's head in, single layer filter extracts probe completely and carried out repeatedly improving to impermeability, but the sealing of probe still exists some problems.Single layer filter extract completely probe each parts between connect sealing adopt be fluororubber sealing gasket, in practical application at the scene, fluororubber pad still there will be catabiosis, once dismounting, just can not play the effect of sealing; 4, gas outlet horizontal positioned, is unfavorable for that pipeline is installed; After single layer filter extracts probe installation completely, gas outlet is the level of state.On-the-spot sampling pipeline is from top to bottom in vertical shape, and pipeline is connected to probe gas outlet, needs to do a circular arc bending, this section of pipeline bending, needs pipeline heating part to peel off, will form some condensate waters herein, affect the accuracy that sample gas is analyzed; 5, probe and heat tracing pipe can not organically combine, and it is install separately that single layer filter extracts probe completely, and after connecting sampling pipeline, the coupling part of sampling pipeline and probe is directly exposed in air.For preventing pipeline from pullling coupling part because of Action of Gravity Field, sampling pipeline is hung on probe by a conventional fine rule, seems lack of standardization.
Summary of the invention
Technical matters solved by the invention is to provide a kind of Novel smog number probe, to solve the problem proposed in above-mentioned background technology.
Technical matters solved by the invention realizes by the following technical solutions: a kind of Novel smog number probe, comprise: sampling pipe assembly, sealing gasket, heating component, filter assemblies, protective housing, O-ring seal, cable splice, described sampling pipe assembly front end is provided with separation hood, sampling pipe assembly is installed in one end of heating component, the other end is provided with filter assemblies, filter assemblies gas outlet goes out to be provided with gas connection, heat tracing pipe is connected to gas connection, protective housing is located at hot component external, be provided with plastics waterproofing box in protective housing, protective housing is also connected with cable splice.
Graphite grazing pad is adopted to seal between described sampling pipe assembly and heating component.
Fluororubber O type circle O-ring seal is adopted to seal between described heating component and filter assemblies.
Compared with prior art, the invention has the beneficial effects as follows: high precision dedusting: adopt the ultramicropore SiC high efficiency particulate air filter with nano-sized hydrophobic characteristic.Filtering accuracy is up to 0.3 μm 99%, and gas-flow resistance is only 100Pa, makes the gas disposal of rear class sample no longer include the worry of dust pollution.
From the heating of limit temperature: adopt PTC from the warm ceramic heating flake of limit.Heating-up temperature 130 ± 5 DEG C.Heating plate life estimation more than 3 years, can effectively overcome the fault that in former design, electrical heating wire easily blows.
Heating is cancelled temperature controller and is controlled, and avoids that temperature controller occurs and damages the incipient fault causing temperature control, reduce cost.Whether platinum resistance-Pt100 thermometric still retains, and is used for showing probe heating-up temperature, normal with detection probe heating.
PTC ceramic heating flake is installed near sample gas exit, is conducive to preventing filtrator sample gas exit from may occur the incipient fault of dust fouling because heating not.Sampling probe outgassing direction changes into vertically downward by original horizontal direction, decreases bending after the connection of sampling pipeline, and pipeline connects more aobvious reasonable and convenient.
Pyramidal structure is made by sampling probe inner chamber stopple coupon one end mounting flange inner cavity chamber of the present invention, is more conducive to the blowout of dust, prevents dust accumulation at probe bore dead angle place; Installing cables joint on protective housing, makes the connection of sampling probe and exterior tubing more coordinate, has integrated style.Sealing between sampling probe sampling pipe assembly and heating component adopts Graphite pad to seal, and adopt fluororubber O type circle to seal between heating component and filter assemblies, sealing effectiveness is better.The electrical connection of sampling probe adopts has the terminal of terminal box to connect, and has taken into account convenience with reliable.
In addition, the present invention can solve original sampling probe heater strip and twine heater strip in loaded down with trivial details, the onsite application process of system and be easy to the problems such as damage, shorten probe and produce the duration, reduce the damage of popping one's head in onsite application process, improve the q&r of sampling probe comprehensively.Improve filter probe device precision, alleviate the pressure of rear class sample gas disposal.Change the direction, gas outlet of probe, sampling probe is organically combined with sampling pipeline, maintenance easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
