Abstract
The utility model provides a boiler fly ash sampling device arranged at the bottom part of an outlet flue of an air pre-heater. The boiler fly ash sampling device is characterized by comprising a sampling bottle, a lower ash falling pipe, an outer sleeve and an ash falling pipe, wherein an opening of the sampling bottle is connected with one end of the lower ash falling pipe, the other end of the lower ash falling pipe is communicated with the ash falling pipe through a flange, and the outer sleeve is arranged between the outlet flue of the air pre-heater and the flange and at the outside of the ash falling pipe. Compared with the prior art, the boiler fly ash sampling device has the advantages that the fly ash drops into the sampling bottle through the own gravity instead of compressed air, so that the sampling device is simple to operate and accurate to sample, can not generate defect easily, and the obtained ash sample can sensitively reflect the change trend of fly ash combustibles.
Description
Technical field
The utility model relates to thermal power plant's sampler, refers to especially a kind of boiler fly ash sampler.
Background technology
Fly ash sampler also claims fly ash sampling device, is mainly used in the sampling of boiler of power plant tail flue gas flying dust, accurately detects unburned carbon in flue dust, for science, calculates boiler thermal output reliable basis is provided.
Existing fly ash sampling device, after the compression smoke gas flow enters the sampling mouth, utilize pressurized air to form the negative pressure ventilation effect, through stopple coupon, enter the Whirlwind cyclone separation vessel along the wall tangential direction, along wall, rotate from top to down again, in rotary course, flying dust, because of the gravity inertial effect, is thrown on wall, and along wall, fall into the grey funnel of collection by Action of Gravity Field and enter sampling jar, and gas is discharged by fairlead.This sampler, higher to compressed-air actuated quality requirements, if pressurized air is moisture more, block, can't normally get the problems such as ash with regard to there will be pipeline.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of pressurized air that do not use, and conducts oneself with dignity and falls to the boiler fly ash sampler in sampling jar by flying dust.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of boiler fly ash sampler, be arranged on air preheater exhaust pass bottom, described sampler comprises sampling jar, lower ash tube, outer tube sleeve and ash tube, the bottleneck of described sampling jar is connected with an end of lower ash tube, the other end of described lower ash tube is communicated with described ash tube by flange, between described air preheater exhaust pass and flange, ash tube is provided with outer tube sleeve outward.
Wherein, described lower ash tube is truncated cone-shaped, and its big opening end is connected with flange, and its osculum end is connected with sampling jar.
The beneficial effect of technique scheme of the present utility model is as follows:
Such scheme, do not used pressurized air with existing comparing, and the deadweight by flying dust falls in sampling jar, and sampler is simple to operate, and accurately, sampler is difficult for occurring defect in sampling, and institute's ash sample of getting can responsive reflection fly ash combustible material variation tendency.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment boiler fly ash sampler.
[main element symbol description]
1, ash tube;
2, outer tube sleeve;
3, flange;
4, lower ash tube;
5, sampling jar.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, embodiment of the present utility model provides a boiler fly ash sampler, be arranged on air preheater exhaust pass bottom, described sampler comprises sampling jar 5, lower ash tube 4, outer tube sleeve 2 and ash tube 1, the bottleneck of described sampling jar 5 is connected with an end of lower ash tube 4, the other end of described lower ash tube 4 is communicated with described ash tube 1 by flange 3, between described air preheater exhaust pass and flange 3, ash tube 1 is outer is provided with outer tube sleeve 2, sampler is arranged on to the bottom of air preheater exhaust pass.
Wherein, described lower ash tube 4 is truncated cone-shaped, and its big opening end is connected with flange 3, and its osculum end is connected with sampling jar 5.
The beneficial effect of technique scheme of the present utility model is as follows:
Such scheme, do not used pressurized air with existing comparing, and the deadweight by flying dust falls in sampling jar, and sampler is simple to operate, and accurately, sampler is difficult for occurring defect in sampling, and institute's ash sample of getting can responsive reflection fly ash combustible material variation tendency.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
