Embodiment
As shown in Figure 1 to Figure 4; the protection watt of the utility model in-situ type gas monitoring instrument high-performance self-cleaning comprises the body 11 of cross section semicircular in shape; body 11 offers strip opening 12 along own axes direction (the body axis L see shown in Fig. 1, Fig. 2); in body 11, corresponding opening 12 is provided with rectangular flat catch 13 along body axis L direction; catch 13 and opening 12 are separated; the length of catch 13 is not shorter than the length of opening 12; wherein, catch 13 and opening 12 are obliquely installed (as Fig. 4).
When actual design, body 11 and catch 13 can be stainless steel and make, and catch 13 is fixed on body 11 inwall via brace rod 15.
Preferably, body 11 can offer be preferably designed for acute angle with the angle of symmetrically arranged two openings of the axle center O of body 11 12, two openings 12.Correspondingly, two catch 13 are also symmetrical arranged with the axle center O of body 11, and as shown in Figure 4, two catch 13 distribute with the kernel of section line L ' specular of body 11, are rendered as two waists of isosceles trapezoid.Certainly, opening 12 quantity body 11 offered is not limited to above-mentioned.
In the utility model, the blocking surface of catch 13 is not that forward is facing to opening 12, but be obliquely installed (from cross section of the present utility model with opening 12, as shown in Figure 4), preferably, as figure, long limit 131, inner side and the body 11 inwall distance apart of catch 13 are less than outer long side 132 and the body 11 inwall distance apart of catch 13, as shown in Figure 5.Here, the medial and lateral of catch 13 recently set according to itself and body 11 long side distance apart, and catch 13 is outer long side with body 11 long side apart near side, is long limit, inner side on the contrary.
When actual design, opening 12 can be made up of (situation that Fig. 1 shows spaced set 7 rectangle holes) spaced some rectangle holes.In the utility model, the object of hole ensures that the tested air-flow carrying volume of smoke particle can be smoothly through the utility model, smoke particle will be caused at the utility model surface sediment because institute's hole-opening is too small, thus affect tested air-flow and pass through.
As Fig. 4, when actual design, in body 11, yoke configurations 14 can be installed.
In actual design, the length of body 11 should to insert the length of the part of flue suitable with the probe of in-situ type gas monitoring instrument (GPP pops one's head in).
As Fig. 1, body 11 of the present utility model can be divided into two parts, and a part offers opening 12; for the protection of porcelain filter 21; and another part maintains the original state, do not offer any hole, for blocking the heat expansion joint (not shown) etc. on protection probe.
During use; as Fig. 5; the protection watt of the utility model high-performance self-cleaning is arranged on the probe of in-situ type gas monitoring instrument, specifically, via yoke configurations 14 and auxiliary auxiliary equipment (not shown), the utility model is fixed on the framework 22 of probe.When the probe installing in-situ type gas monitoring instrument of the present utility model is stretched into after in flue, make opening 12 of the present utility model towards tested gas flow direction (flow direction of tested gas is essentially direction from top to bottom), catch 13 is roughly positioned at the top of porcelain filter 21, and opening 12 and catch 13 relative with porcelain filter 21 is between opening 12 and porcelain filter 21.
So, as Fig. 5, carry the tested gas of smoke particle from top to bottom (as shown in Fig. 5 hollow arrow) flow through opening 12, two-way is divided into after running into catch 13, most tested gas (primary air) flows downward (as shown in the arrow of band shade in right side in Fig. 5) along the inclination blocking surface outside catch 13, the tested gas (air-flow) of all the other fractions then flows downward (as shown in left side filled arrows in Fig. 5) along the surface (with the one side that blocking surface is opposing) inside catch 13, namely catch 13 achieves shunting to tested gas.
In this state, under the partial pressure differential impact that quality large smoke particle 30 bigger than normal produces in self inertia effect and two-way air-flow difference, cannot move with an air-flow, and can only be move with primary air, thus achieve smoke particle from " inertial separation " tested gas.So the large smoke particle 30 of following primary air is taken away porcelain filter 21, flows out probe with primary air, serve the effect of dedusting automatically cleaning and protection porcelain filter.Prop up air-flow then to participate in measuring, and be no matter the self inertia effect of smoke particle, or the partial pressure differential that the shunting action of catch 13 produces between two-way air-flow, capital makes the dust in an air-flow disappear, and flowing velocity accelerates, thus an air-flow is fully contacted with porcelain filter 21 better, reach the effect improving and measure response speed and accuracy.
It should be noted that in addition, due to the existence of an air-flow, therefore effectively can suppress porcelain filter 21 surface caused because of turbulent phenomenon below catch 13 that dust deposit occurs, porcelain filter 21 outside surface can be made to obtain maximum flow area.
As Fig. 5, in use, no matter armoured thermocouple 23 is positioned at top or the below of porcelain filter 21, all can be protected, if be positioned at top, then what be subject to catch 13 blocks protection, if be positioned at below, then what be subject to porcelain filter 21 blocks protection.Part body 11 not being offered opening 12 then can be used to block other device or the positions such as the heat expansion joint on protection probe.
The utility model has the advantages that:
The utility model structure is simple, practical, the catch of its design, under the effect of fluid mechanics principle, utilize self mobility of tested gas, the self-cleaning effect of flue dust can be reached on the one hand, greatly reduce large smoke particle in tested gas to the wearing and tearing of measuring sensor (porcelain filter) and blocking, available protecting is exposed to the probe (GPP probe) of the in-situ type gas monitoring instrument in flue, extend its serviceable life, also can accelerate tested gas does not destroy gas sampled representativeness by the flowing velocity of measuring sensor on the other hand, effectively guarantee response speed and the accuracy of measurement.
The above know-why being preferred embodiment of the present utility model and using; for a person skilled in the art; when not deviating from spirit and scope of the present utility model; any based on apparent changes such as the equivalent transformation on technical solutions of the utility model basis, simple replacements, all belong within the utility model protection domain.
