Abstract
The utility model discloses a sampling probe used for a hot flue gas analysis system. The sampling probe can be used for continuously extracting flue gas under high temperature and high dust concentration environmental conditions such like the charging end of a cement mill, the outlet of a decomposition furnace, etc. The sampling probe is characterized in that a water cooled jacket is arranged outside a sampling tube. A water washing device is arranged at the center of the sampling tube. The water washing device comprises a water supply tube and a spray nozzle. The water supply pipe can lead high pressure water to the spray nozzle at the front part of the probe, and then the high pressure water can be sprayed out of axial and tangential holes of the spray nozzle. Thus, the hot flue gas can be cooled, the dust can be removed, and the sampling tube can be washed for preventing that the sampling tube is clogged by the dust in the flue gas. The rear end of the sampling tube is provided with an adjustable mounting flange. Thus, the sampling tube can freely slide in the flange for matching different depths of sampling requirements.
Description
The utility model relates to a kind of hot flue gas analysis systematic sampling probe, is specially adapted to continuous drawing flue gas under high temperature, the high dust atmosphere conditions such as cement mill kiln tail and dore furnace exit, belongs to the technical analysis field.
Three sampling spots are generally established in the hot flue gas analysis of rotary cement kiln, kiln tail, dore furnace outlet and the outlet of kiln tail blower fan.Because these local flue-gas temperatures are very high, and dustiness is big, easily cause probe to stop up, and easily burnt out, the sampling probe (seeing accompanying drawing 5) of the CJ-06 type oxygen analysis system that Sichuan analytical instrument factory commonly used at present produces, be that one one end stretches in the kiln, the straight tube that the other end connects with water ejector, straight tube is welded on kiln tail fixed part top, with the angle of pedal line less than 30 ℃, the shortcoming of extraction mode is the very easy inflow probe of the water in (1) water ejector, and probe is drenched, dust in flue gas is sticked in the probe, and it is very fast blocked to pop one's head in.(2) because the no cooling device of probe burns out easily, that can not do is oversize, thereby can not go deep into the kiln deep and obtain representational gas sample.
Task of the present utility model is: at the requirement and the characteristics of cement rotary kiln flue gas analysis, overcome the shortcoming that prior art exists, design a kind of difficult obstruction, easy burn-out is not easy to use, can satisfy the high-temperature flue gas sampling probe of customer requirements.
The novel technical scheme of this use is that (1) installs water cooling plant outside stopple coupon, in order to avoid burn out stopple coupon.(2) at the stopple coupon center water washing device is installed, water under high pressure is caused the probe front end, to hot flue gas cool off, dedusting; And flushing sampling tube wall, in order to avoid stop up stopple coupon.(3) adorn adjustable mounting flange in the stopple coupon rear end, probe can be fixed on on-site sampling point place.And according to the sampling requirement of different depth, stopple coupon can be in flange sliding extension.
Narrate three chief components of the present utility model below in conjunction with Figure of description:
(1) water-cooled part: outside stopple coupon, install water collar, water collar is made of pipe 9 in water collar outer tube 8 and the water collar, chilled water flows between the pipe 9 in stopple coupon 10 water collars, flow out between pipe 9 and the water collar outer tube 8 in the water collar, because water-cooled cooling effect, the stopple coupon life-span is prolonged greatly, and can be deep into the different depth sampling of kiln.
(2) hydro-peening head part, this part is made of hydro-peening head 5 and feed pipe 11, and both connect with taper-thread, are installed in the stopple coupon 10, connect high pressure water system behind the feed pipe 11, and the effect of this part is cooling, purifies flue gas, and the flushing sampling line prevents to stop up.
Hydro-peening head 5 has an aproll sheet 22, four axial holes 23 and four tangential holes 24, the inboard of aproll sheet 22 is spheres, water under high pressure by axial hole 23 ejections bumps against on the sphere of aproll sheet 22, be scattering into a umbrella shape cascade, the contained part dust of flue gas Shanghai is fallen, thereby reach the purpose of rough purification flue gas, hydro-peening head 5 also has four tangential holes 24, two in the A-A face, in addition two in the B-B face, form the strong flushing band of certain width at the front end of stopple coupon 10 by the water under high pressure of tangential hole 24 ejections, its effect is to prevent that dust in flue gas from sticking to stopple coupon 10 front ends, cause that probe stops up, this part water washs flue gas in addition in addition, the effect of flushing stopple coupon and flushing sampling catheter (in the stopple coupon back), for washing action more effective, when probe is installed, its front end is lifted with surface level form an elevation angle, this angle generally is not less than 15 ° of (see figure 1)s, can make water in its deadweight with give under the acting in conjunction of the negative pressure that the water ejector in the treating apparatus 3 produces like this, flow out rapidly, play sufficient washing action.
(3) mounting flange is enclosed within on the probe water collar outer tube, and both can slide relatively, to adapt to the sampling requirement of different depth, tighten plug 14, and extruding asbestos rope 13 just can be fixed on flange water collar outer tube any place.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:
Water collar outer tube 8 two ends are taper-thread, and an end and pipe cap 6 link, and the other end is screwed into multitube fittings body 15, and the interior pipe 9 of a water collar only end has taper-thread and multitube fittings body to link, and the other end is built on stilts with it by three pawls 7.Stopple coupon 10 two ends are taper-thread, one end connects with pipe cap 6, the other end passes in multitube fittings body 15, then with the thread connection of the straight-through part of threeway 18, the other end of straight-through part connects with plug formula seal 19, tighting a bolt makes gland 17 compress immersion oil asbestos rope 16, can guarantee the sealing between stopple coupon 10 and the multitube fittings body 15.Hydro-peening head 5 is the vital part (see figure 3) on the probe, its front end is an aproll sheet 22, aproll sheet inboard is a sphere, there are four axial holes 23 centre, four tangential holes 24, the back is a taper-thread 25, one end of this screw thread and feed pipe 11 links, the other end of feed pipe 11 passes in threeway 18 and plug formula seal 19, the seal plug 21 of screwing on compresses immersion oil asbestos rope 20, can guarantee the sealing between feed pipe 11 and the plug formula seal 19, unclamp seal plug 21, then can move forward and backward feed pipe 11, adjust the distance that hydro-peening head 5 stretches out pipe cap 6, make press water spray from four axial holes, bump against on the sphere of aproll sheet 22, the garden shape cascade that forms after the scattering is sealed the porch that flue gas enters stopple coupon 10 just, after flue gas enters stopple coupon 10, with the water of four tangential holes, 24 ejections, flow to threeway 18 backward along stopple coupon 10, change 90 ° of outflows then.After chilled water enters multitube fittings body 15, mezzanine space flow direction probe front end in stopple coupon 10 and cooling jacket between the pipe 9 is turned back 180 ° from pipe cap 6, and the mezzanine space between pipe 9 and the water collar outer tube 8 refluxes in water collar then, at last, flow out from multitube fittings body 15.
