Embodiment 1
[0097] to combine figure 2 Be explained. figure 2 Explanation of symbols in: filter 1; mounting plate 3; probe rod 8; sensor 9; first heat exchanger 52; gas jet housing 105a; jet nozzle 105b; transverse cylinder 105c; ; Compressed air supply mechanism YG; Sampling solenoid valve QYDCF.
[0098] Such as figure 2 As shown, the high-temperature flue gas detection and sampling equipment in this embodiment has: a mounting plate 3, a filter 1, a probe rod 8 made of steel pipe, a sensor 9 including a detection probe, and an automatic control circuit.
[0099] The detection probe of the sensor 9 is located in the channel through which the sample gas flows, such as figure 2 shown. Sensor 9 links to each other with automatic control circuit by wire (automatic control circuit and wire are in figure 2 are not shown).
[0100] figure 2 Only one side of the flue wall 201 is drawn. Driven by the negative pressure, the high-temperature flue gas in the flue wall 201 as the sample...
Embodiment 2
[0106] to combine Figure 6 to Figure 26 Be explained.
[0107] In this embodiment, an important part called base 5 is used. Figure 6 It is a schematic diagram of the base parts, and the base in this picture has not been assembled with other parts; Figure 7 yes Figure 6 Left view; Figure 8 yes Figure 6 right view of Figure 9 yes Figure 6 top view of Figure 10 yes Figure 6 A-A sectional view of , after the opening of the vertical sub-hole marked 5-2b is completed, the upper part of the vertical sub-hole is blocked with a process block marked 31; Figure 11 yes Figure 9 B-B direction sectional view.
[0108] The base 5 in this embodiment is assembled with other components. Figure 12 It is a schematic diagram of the base assembly. The base in this picture has been assembled with other parts. The parts assembled in this picture include sensors and other parts; Figure 13 yes Figure 12 left view of Figure 14 yes Figure 12 right view of Figure 15 yes ...
Embodiment 3
[0135] The above second embodiment has been greatly improved compared with the prior art, but there is still room for further improvement. In the second embodiment, the compressed air sent into the blowback air pipe 7 needs to be heated by the heating mechanism JRJG first; therefore, heating machines and temperature control instruments are still required; thus, not only need to invest costs, but also increase the probability of failure.
[0136] For this reason, the third embodiment is further improved on the basis of the equipment in the second embodiment. The main content and main measures of the improvement are: 1. The compressed air that was originally sent into the blowback air pipe 7 needs to be heated by the heating mechanism JRJG first, and this heating method is now removed; Two exchange air inlets and second exchange air outlets; 3. Increase the second heat exchanger 53.
[0137] The improved base 5 is provided with: the first exchange air inlet 5-7a, the first exch...
