Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

All the electrical components in the present application are connected with the power supply adapted to the electrical components through a wire, and an appropriate controller and an appropriate encoder should be selected according to actual conditions to meet control requirements, and specific connection and control sequences should be obtained.

Example (b): as can be seen from fig. 1-3, the fixing structure mainly comprises: a fixing plate 3 and a joint 4; the fixed plate 3 is arranged on the sampling tube 1, the detector 2 is arranged at the other end of the fixed plate 3, the joint 4 is inserted into the fixed plate 3, and one end of the joint 4 is connected to the sampling tube 1; the fixed plate 3 is provided with a protective cover 5, and the protective cover 5 is sleeved outside the detector 2; a smoke temperature preheating filter 7 is arranged in the protective cover 5, the smoke temperature preheating filter 7 is connected to the joint 4, and the other end of the smoke temperature preheating filter 7 is connected to the detector 2; the filter element 6 adopts a ceramic structure of 0.5 um.

From the above, it follows: through with sampling tube 1 from the regional or high dust area of coal gas with the air adsorption to sampling tube 1 in, take a sample through filter core 1, filter core 7 adopts 0.5 um's ceramic structure, corrosion-resistant, high temperature resistant, simple structure, long service life, it is convenient to change, ceramic filter core is owing to choose for use to be pure natural physical material, powerful advantage is exactly not afraid of the jam, can adapt to very abominable condition, is a full-round player. And the filter core of some inferior membrane filtration modes can better work under better condition, but will be blockked up by silt sand rust when relatively poor, bacterium suspended solid etc. gradually, and then lose the filter effect, preheat filter 7 through gas temperature in the safety cover 5 simultaneously, need not the external heating device of probe, can be applied to the regional and high dust region of coal gas, reduce the explosion hidden danger, current detection device most needs heating device, in the regional and high dust region of coal gas, the emergence of the postexplosion burning phenomenon appears easily in the high temperature, be used for shutoff pipeline mouth through DN50 blind flange 8. The functions of the sealing device are the same as those of the end socket and the pipe cap, but the blind plate seal is a detachable sealing device, and the end socket seal is not prepared to be opened, so that parts in the protective cover 5 can be detached and are better protected.
