Abstract
The utility model discloses a backflowing type gas sampling probe. The backflowing type gas sampling probe comprises a sampling tube, a stop valve and a filter, which are connected in sequence; a sleeve provided with a reflow cavity is arranged between the stop valve and the filter. According to the utility model, backflowing and filtering are integrated, so that the effect of separating and removing dust, fume and tar oil in sample gas can be improved generally.
Description
Technical field
The utility model relates to a kind of before sample gas enters analyser, and sample gas is carried out to pretreated reverse-flow type gas sampling probe.
Background technology
In order to ensure that sample gas is sampled to the analysis precision of analyser, guarantee analyser smoothly, extend the serviceable life of himself simultaneously, measured sample gas is sampling cleaning smoothly.Therefore, sample gas is entering before sample gas analyser carries out Measurement and analysis, at first needs sample gas is taken out and pass through the liquid mist separation of sampler and dust, tar filtration treatment smoothly.
Existing sampling probe is the simple and easy probe with filtrator, rely on filtrator to be filtered sample gas, the dust of removing in sample gas is had to good effect, but the removal effect to the liquid mist (fog-like liquid) in sample gas, tar, drop is very low, the not only impact analysis precision of sample gas parts that contains the liquid mist, but also analyser is caused to security threat, therefore need the device that adopts in addition other further to remove tar, reach the liquid mist, increase cost, made the structure of sample gas processing system become complicated.
The utility model content
For above-mentioned weak point of the prior art, the utility model provides the reverse-flow type gas sampling probe, by refluxing, with filtration, combine, and the whole separation removal effect that improves dust, liquid mist and tar in sample gas.
The technical solution of the utility model is a kind of reverse-flow type gas sampling probe, comprises the stopple coupon, stop valve and the filtrator that connect successively, is provided with the sleeve with back cavity between described stop valve and filtrator.
In technique scheme, enter into the sample gas of back cavity, due to the weight effect, the backflow that can descend of the particle of the coarsegrains such as the dust carried in sample gas, drop, tar, gas can rise and enter into filtrator, arrives the effect of gas-liquid separation; Sample gas further separates short grained liquid mist, tar etc. out in filtrator again; Realized that minute two-stage is processed sample gas, filtered compared with simple dependence filtrator, significantly improved the separation removal effect of dust in sample gas, liquid mist and tar.
Further, be provided with the shunting rod in the back cavity of described sleeve, the excellent inner hollow of described shunting, its two ends are the frustum of a cone.The shunting rod can be shunted the sample gas that enters into back cavity, makes the diffusion of sample gas more even, but its inner hollow weight reduction, and two ends are that the frustum of a cone has guide functions to sample gas.
Further, described filtrator has the double medium filtration fiber.Described double medium filtration fiber is respectively hydrophilic glass fiber, stainless steel fibre.Filter fiber can make the fine liquid mist in sample gas condense into the liquid mist than coarsegrain, finally condense into drop, under Action of Gravity Field, is back to back cavity.
Further, described stopple coupon, stop valve, sleeve and filtrator connect by flange.The gas outlet end of described filtrator is provided with the mounting flange connected for same gas analyser, and described mounting flange is provided with the outlet of sample gas.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is use view of the present utility model.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of reverse-flow type gas sampling probe, as shown in Figure 1, comprise the stopple coupon 1, stop valve 2 and the filtrator 5 that connect successively, is provided with the sleeve 3 with back cavity between described stop valve 2 and filtrator 5.
Further, be provided with shunting rod 4 in the back cavity of described sleeve 3, excellent 4 inner hollow of described shunting, its two ends are the frustum of a cone.Shunting rod 4 can be shunted the sample gas that enters into back cavity, makes the diffusion of sample gas more even, but its inner hollow weight reduction, and two ends are that the frustum of a cone has guide functions to sample gas.
Further, described filtrator 5 has the double medium filtration fiber.Described double medium filtration fiber is respectively hydrophilic glass fiber, stainless steel fibre.Filter fiber can make the fine liquid mist in sample gas condense into the liquid mist than coarsegrain, finally condense into drop, under Action of Gravity Field, is back to back cavity, and the double medium filtration fiber can improve filter effect.
Further, described stopple coupon 1, stop valve 2, sleeve and 3 filtrators 5 connect by flange.The gas outlet end of described filtrator 5 is provided with the mounting flange connected for same gas analyser, and described mounting flange is provided with sample gas outlet 6.
The course of work of the present utility model is as follows, by in stopple coupon 1 insertion process pipeline 7, open stop valve 2, sample gas rises in the back cavity in sleeve 3 from process pipe 7, 4 pairs of sample gas of shunting rod are shunted, under the weight effect, dust in sample gas, drop, the particle of the coarsegrains such as tar can descend and be back in process pipe 7 in back cavity, the gap of sample gas between the inner core of flange and filtrator 5 through primary separation enters into filtrator 5, double medium filtration fiber in filtrator 5 can make the fine liquid mist in sample gas condense into the liquid mist than coarsegrain, finally condense into drop, be back to back cavity under Action of Gravity Field in, and then be back in process pipe 7..
Final clean sample gas takes out from sample gas outlet 6, and can carry out blowback by sample gas outlet 6, and remaining a small amount of dust, dust, drop, tar also are back to process pipe 7, play the effect of protection filtrator 5.
The above technical scheme that the utility model embodiment is provided is described in detail, applied specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, on embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model simultaneously.
