Description
Technical field:
The utility model relates to the industrial circle gas sampling device.
Background technology:
In the commercial production field, gas analyzer is a common equipment, and by sampling probe, sampling pump extracts sample gas and carries out gas analysis.Existing gas analyzer sampling probe adopts ceramic filter cylinder or copper powders may alloy filter cylinder, generally is installed in the exhaust gas channel of fly-ash separator inlet, and the problem of existence is: 1, sampling probe directly exposes in swiftly flowing dust-laden tail gas, and abrasion condition is serious.2, because the suction of sampling pump forms negative pressure at the sampling probe place, and dust accumulates in the filter cylinder surface, be easy to cause filter cylinder to stop up, approximately just needed in 2-3 days to clean once.3, filter cylinder stops up the back and cleans difficulty, after the cleaning for several times, must not upgrade when reaching by standard, because price is higher, causes purchase cost too high.4, stop up a series of problems of bringing: the frequent startup-shutdown of equipment, accessory damage, consume, and frequent maintenance and maintenance cause equipment work unreliable, cause the operation of fly-ash separator to have potential safety hazard, have also increased personnel labor.
The utility model content:
The purpose of this utility model provide a kind of wearing and tearing and plugging fault few, the maintenance of equipment amount is little, the gas analyzer sampling device of working stability.
Gas analyzer sampling device of the present utility model comprises sampling probe, and sampling probe comprises filter cylinder, sample tracheae, and the sample tracheae passes from filter cylinder.The utility model also comprises protective sleeve, and sampling probe is located in the described protective sleeve; Has certain space between protective sleeve and the sampling probe; Protective sleeve is the cyclone dust removal formula; The protective sleeve sidewall has air admission hole, and the bottom has ash-hole.
In order to reach better technique effect, the utility model also comprises sampling cabinet, and sampling cabinet is an opening, the casing of other face closures; Sampling cabinet is located on the exhaust gas channel, and the opening surface of sampling cabinet is to exhaust gas channel; Described protective sleeve is installed in the sampling cabinet.
Sampling probe and protective sleeve are vertically fixed in the sampling cabinet, are an angle of 90 degrees with the tail gas air-flow.
The air intake opening of protective sleeve is towards exhaust gas channel one side.
Sampling cabinet preferably is located on the fly-ash separator hydraucone sidewall.
The utility model places protective sleeve with sampling probe, and protective sleeve is arranged in the sampling cabinet again.Sampling cabinet can effectively prevent dust-laden tail gas to directly the washing away of sampler, play reduce to wear and tear effect, sampling cabinet is the one side open formula, can make the sample gas that enters in the protective sleeve form swirling eddy, plays the effect of cyclone dust removal better; Protective sleeve protection sampling probe is not by high speed dust brinelling, and the protective sleeve of cyclone duster structure formula has the effect of carrying out primary dust removing again to tail gas simultaneously, has reduced the dust content by the tail gas of filter cylinder effectively.Sampling is selected on the fly-ash separator inlet end hydraucone sidewall; be because after tail gas enters hydraucone by passage here; the space increases; flow velocity reduces; wearing and tearing to protective sleeve just reduce naturally; dust also has the part natural subsidence at the hydraucone place in addition, and the sample gas dustiness of extraction reduces, and helps extracting sample gas.

Embodiment:
The utility model is described in further detail below in conjunction with embodiment.
There are tens of electric dust-removing equipments in Wuhai City, Inner Mongol Xi Shui foundation incorporated company for producing more than 200 ten thousand tons of Cement Production enterprises per year, and gas analyzer is widely used.Existing gas analyzer sampling probe structure as shown in Figure 1, sampling probe is by ceramic filter cylinder 9, sample tracheae 10, filter cylinder is fixed on the holder 12 by clamp nut 11, the sample tracheae is come by pass-out in the filter cylinder.Sampling probe is installed in the inlet end of electric precipitator, directly expose in tail gas, because the dust content in the tail gas is very high, dust is attached on the filter cylinder when extracting sample gas, be easy to cause filter cylinder to stop up, stop up the back permeability and descend, sample gas can't the suction gas analyzer, cause equipment to lose due function, analyser can't operate as normal; The method of removing the filter cylinder superficial dust is to utilize high-pressure blast to carry out blowback, carries out a blowback in 10 minutes at interval and can not solve root problem, has also caused the frequent startup-shutdown of equipment, and material, accessory consumption are big, and the maintenance, repair amount increases.After filter cylinder stopped up, blowback wind was obstructed, and as easy as rolling off a logly caused ceramic filter cylinder to burst because pressure is excessive, and dust enters pipeline in a large number, and the sample feed channel is stopped up, can't operate as normal; Filter cylinder exposes in tail gas, because condition of work is limit, the dramatic temperature that bear suddenly cold and hot changes, and is easy to burst; Big dust particle carries down at swiftly flowing tail gas, and the bump filter cylinder also is easy to cause ceramic filter cylinder breakage.The pottery filter cylinder is in buying, carrying, all damages easily when changing.In order to overcome the defective on the material, company uses ceramic filter cylinder instead copper powders may alloy filter cylinder, and wearing and tearing and blockage problem still frequently take place.
For capturing this technical matters, company has set up tackling key problem group, has worked out new technical scheme and has produced experiment, has solved problem.
New gas analyzer sampling device comprises sampling cabinet 3, protective sleeve 2, sampling probe 1 as shown in Figure 2.Sampling cabinet 3 is located on the sidewall of hydraucone 4 of electric precipitator, as shown in Figure 4.Sampling cabinet 3 is openings, the casing of other face closures, and the one side of sampling cabinet opening is towards the electric precipitator inner chamber, promptly towards the tail gas air-flow.As Fig. 2, shown in Figure 3, sampling probe 1 is located in the protective sleeve 2, has certain space between protective sleeve and sampling probe, and protective sleeve 2 is the cyclone dust removal formula, has the basic configuration of tornado dust collector, and the protective sleeve sidewall has air admission hole 5, and the bottom has ash-hole 6.Protective sleeve 2 and the sampling probe 1 that is placed in one are fixed in the sampling cabinet.As shown in Figure 4; the direction of arrow is the tail gas airflow direction; during installation; sampling probe 1 is vertically fixed in protective sleeve and the sampling cabinet, is an angle of 90 degrees with the tail gas air-flow, and promptly sampling probe is vertically installed; flow level flows; the protective sleeve air intake opening should reach the side near the tail gas air-flow towards the inboard of exhaust gas channel, and being drawn into the sample gas that comes like this could turn in the protective sleeve inward turning, reaches the purpose of cyclone dust removal.
Sampling probe comprises filter cylinder 7 and sample tracheae 8, and sample tracheae 8 passes from filter cylinder 7.Filter cylinder uses copper powders may alloy filter cylinder, physical strength height, the counter-blowing wind-pressure power that can bear 0.8KPa.
For ease of dismounting, sampling probe 1 is fixed by flange and protective sleeve and sampling cabinet.
After using above device, equipment operation is normal, the cycle of operation was by original 7-10 days, bring up to present more than 300 days, daily servicing, easy to maintenance, simple, quick, material, accessory consumption are little, demand for capital is little, personnel labor declines to a great extent, and stable equipment operation is reliable, and normally moving for the safety of fly-ash separator provides effective guarantee.
