Abstract
The utility model discloses a kind of gas sampling gun, during detection, it is connected on flue, it comprises the sampling gun (1) of more than two different lengths, bundled and afterbody flushes by clip (2) colligation for more than two different length sampling guns (1), is provided with flexible pipe connection (3) at the afterbody of sampling gun (1).The utility model is bundled and afterbody is flushed by clip colligation by more than two different length sampling guns, and be provided with flexible pipe connection at the afterbody of sampling gun, during use, measurement flexible pipe is connected from different sampling guns respectively, the sampling analysis to different depth position sampled point in same gaging hole can be realized like this when not pulling sampling pipe, overcome due to on-the-spot test platform condition limit the caused inconvenience pulling sampling pipe back and forth.
Description
Technical field
The utility model relates to a kind of gas sampling gun, belongs to flue gas pollutant sampling apparatus field, fuel-burning power plant.
Background technology
The measurement of fuel-burning power plant flue gas need meet different depth, therefore the existing measuring method to gaging hole a certain on flue section is, the gas sampling gun meeting length requirement with is measured by being deep to shallow or pointwise from shallow to deep.But along with fired power generating unit capacity is increasing, flue sectional area is increasing, adopt existing mode will be more and more longer to the length requirement of gas sampling gun, in employing process, when needing the flue gas pollutant measuring more shallow position sampling point, sampling gun just needs outer drawing, along with sampling point position is more and more shallow, the sampling gun gun barrel of exposed to air will be more and more longer, and more and more longer sampling gun in use exists following inconvenience:
1, owing to being transported and the restriction of spot sampling condition, the length of gas sampling gun is restricted, and is difficult to the requirement meeting spot sampling.
Even if the length long enough of 2 gas sampling guns, meet sampled point far away and measure requirement, but this rifle is when nearlyer sampled point is measured, very long one section of sampling gun barrel exposed to air will be had, connecting hose simultaneously because connecting sampling pipe and analysis meter can be longer, like this under the environment that air themperature is lower than flue-gas temperature, is exposed in sampling gun pipeline section in air and connecting hose and has hydrogenesis, flue gas pollutant sampling is impacted, measurement result is departed from.
3, that long sampling gun and long connecting hose operate in sampling location is very inconvenient, detection efficiency is lower.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of and reduce thermal power generation unit flue gas pollutant measuring error, solve flue gas pollutant sampling operation constant, improve the gas sampling gun of flue gas pollutant sampling efficiency, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: gas sampling gun, during detection, it is connected on flue, it comprises the sampling gun of more than two different lengths, and bundled and afterbody flushes by clip colligation for more than two different length sampling guns, is provided with flexible pipe connection at the afterbody of sampling gun.
Flexible pipe connection bends afterwards and sampling gun is 20-50 ° of angle.
Compared with the prior art, the utility model is bundled and afterbody is flushed by clip colligation by more than two different length sampling guns, and be provided with flexible pipe connection at the afterbody of sampling gun, during use, measurement flexible pipe is connected from different sampling guns respectively, the sampling analysis to different depth position sampled point in same gaging hole can be realized like this when not pulling sampling pipe, overcome due to on-the-spot test platform condition limit the caused inconvenience pulling sampling pipe back and forth; Greatly shorten the connecting hose length between sampling pipe and sampling analysis instrument, solve steam in flue gas and exposing a large amount of condensation drawbacks in sampling pipe and connecting hose to the open air; According to smoke pipe diameter design sampling gun length, the accurate setting to each point position of smoke pipe can be realized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
embodiment 1: as shown in Figure 1, the manufacturing process of this device is as follows:
(1) boundling adopts the making of pipe
Make material: Ф 10mm stainless-steel tube, make foundation: according to the regulation of GB/T16157-1996 " in Concentration in Fixed Pollutants Source, particle measures and the gaseous contaminant method of sampling "; Namely length, quantity are determined according to flue cross-sectional dimension; With fuel-burning power plant for 300MW and above unit for main force's genset, its flue cross-sectional area is greater than 9 square metres, and the little block length edge lengths of its flue section homalographic is not more than 1 meter, and sampling number is not more than 20 in principle.Therefore when making boundling and adopting pipe, the longest sampling pipe length is decided to be 5 meters, and all the other are followed successively by 4 meters, 3 meters, 2 meters, 1 meter, its one end is about the angle that 10cm place curves 30 ° and makes flexible pipe connection (3), is convenient to the connection of flexible pipe (4).According to on-site actual situations, stainless-steel tube also can be decided to be other length ratio, but will meet the requirement of GB/T16157-1996 to sampled point.
(2) assembling of boundling sampling pipe: be fixed together prior by subscribing the stainless-steel tube stainless steel anchor ear made of length, have bent angle in same one end, bent angle outwardly, and is numbered; Then use stainless steel lathe dog (2) by bundled for the colligation of more than two different length sampling guns (1), clip (2) can be a stainless steel sleeve.
During use, this device is put into flue gas sampling gaging hole to bosom, flexible pipe (4) one end connects sampling analysis instrument (5), after flue gas pollutant sampling starts, respectively connecting hose connection (3) need not mobile boundling sampling pipe successively for the flexible pipe other end, can measure the flue gas pollutant of each sampling point position.
Claims (2)
1. a gas sampling gun, during detection, it is connected on flue, it is characterized in that: it comprises the sampling gun (1) of more than two different lengths, bundled and afterbody flushes by clip (2) colligation for more than two different length sampling guns (1), is provided with flexible pipe connection (3) at the afterbody of sampling gun (1).
2. gas sampling gun according to claim 1, is characterized in that; Flexible pipe connection (3) bending after and sampling gun (1) in 20-50 ° angle.
