Abstract
The utility model relates to a flue gas sampling tube, which relates to the flue gas sampling tube for analyzing and sampling flue gas. The sampling tube is characterized in that the structure of the sampling tube comprises a sampling tube body which is a long tube whose one end is sealed, wherein a strip-type sampling slit aperture is arranged on the tube wall of the sampling tube in the direction of the tube length, a sealing plug whose middle portion is provided with a through-hole and which is in a truncated cone shape is inserted into the air outlet end of the sampling tube body. The flue gas sampling tube of the utility model is characterized in that the sampling slit aperture for sampling gas on the sampling tube is long, thereby the tube can sample in a bigger radial range, which guarantees the sampled gas samples to be representative and uniform. Furthermore, since the sampling slit can oppositely face the gas flowing direction when sampling, gas can easily enter the sampling tube under the function of the inertia. One end of the sampling tube is provided with a rubber stop, which can prevent air from flowing into the flue.
Description
Technical field
A kind of flue gas stopple coupon relates to a kind of flue gas stopple coupon that is used for the flue gas analysis sampling.
Background technology
In recent years, along with the restriction to industrial gas emission is more and more stricter, also more and more important to the detection and the monitoring of industrial gaseous waste.In order to obtain testing result accurately, an important and requisite link is exactly to collect representative gaseous sample from flue.Generally all be to adopt a metal tube vertically to be inserted in the flue to gather when flue gas being taken a sample, gas enters from the end of stopple coupon, by gas pump inflow gas sampling bag or gas detection equipment in the past.This stopple coupon has following shortcoming: at first, because often diameter is bigger for the flue of collection industrial gaseous waste, what have reaches several meters, be certain to occur the uneven situation of distribution of gas on the interior different cross section of flue, and the top stopple coupon of mentioning is owing to adopt terminal air inlet, the unavoidable like this gaseous sample of choosing the road through that makes is inhomogeneous, does not have representativeness; Secondly, because it is vertical with flue gas flow direction that stopple coupon is got the pore direction, and be generally negative pressure in the flue, therefore flue gas inflow stopple coupon resistance is bigger, need to adopt powerful gas pump, once more, stopple coupon in the past is not owing to there is packoff, air is flowed into from the pore of getting of flue, make troubles for the discharging of sampling and flue gas.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned technology, a kind of flue gas stopple coupon that can collect uniform gaseous sample, can reduce the fashionable resistance of gas stream to be provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of flue gas stopple coupon is characterized in that the structure of this stopple coupon comprises:
One sampling body---should be the long tube of end sealing, and on the sampling tube wall, prolong the pipe range direction and have bar shaped sampling seam hole;
Sealing-plug---sealing plug is the middle truncated cone shape that has through hole, interts to be set in sampling body gas outlet end.
A kind of flue gas stopple coupon of the present utility model is characterized in that covering filter cloth or filter screen on described sampling seam hole.
A kind of flue gas stopple coupon of the present utility model owing to the sampling seam hole of carrying out the gas sampling on the stopple coupon is long, can be taken a sample in the bigger radial extension of flue, has guaranteed the representative and homogeneity of the gaseous sample of getting.This sampling seam hole can be over against the flow of flue gas direction when taking a sample in addition, and flue gas enters in the stopple coupon under action of inertia easily.One end of stopple coupon has tapered rubber stopper, can prevent that air from flowing into flue.
Description of drawings
Fig. 1 is the new structural representation of this practicality.
Embodiment
A kind of flue gas stopple coupon, the structure of this stopple coupon comprises: a sampling body 1---should be the long tube of end sealing, and on the sampling tube wall, prolong the pipe range direction and have bar shaped sampling seam hole; Sealing-plug 2---sealing plug is the middle truncated cone shape that has through hole, interts to be set in sampling body gas outlet end; On described sampling seam hole, cover filter cloth or filter screen 3.
