Description
Technical field
The utility model relates to spiral-flow type fly ash constant speed sampler, belongs to sampler apparatus field.
Background technology
At present, the coal dust of domestic power plant and the sampling method of unburned carbon in flue dust adopt impacting type sample analysis substantially; Or adopt and amass formula sampling.Because these methods owe science, be difficult to obtain real and meet the sample of the actual composition of flying dust, so just bringing difficulty to the canonical measure of unburned carbon in flue dust.This just illustrates: if with lacking representational flying dust sample determination carbon content, then calculate the thermal efficiency according to these data, the inaccurate confidence level that causes of the thermal efficiency reduces.
Existing sampler is in sampling project, and severe due to environment, use instrument for a long time, wearing and tearing and collision, make sampler occur leaking, sampling result is inaccurate, and secondly, blocking pipe after sampling, normally cannot work, delay operation.
In order to solve the problem, applicant proposes a kind of spiral-flow type fly ash constant speed sampler.
Utility model content
In order to solve the leakage that existing fly ash sampler occurs due to gouging abrasion, the problems such as blocking, propose a kind of spiral-flow type fly ash constant speed sampler.
The utility model adopts following technical scheme:
Spiral-flow type fly ash constant speed sampler, the pressurized air mouth right-hand member of sampler is provided with tensimeter, manometric right-hand member connects pressure transfering appts, be connected with cyclone separator below pressure transfering appts, sampling jar is provided with below cyclone separator, described pressure transfering appts and cyclone separator right-hand member are all provided with sampling operation valve, the right-hand member of sampling operation valve is provided with only valve of retreating, described advance and retreat are stopped valve and are located at and go back on defense on pipe, its left end is provided with packing ring, the left end laminating rubber ring of packing ring, going back on defense, pipe is provided with packing_seal outward, is provided with valve and mends core outside packing_seal; Described sampling operation valve and go back on defense between pipe and be provided with retaining spacing ring; The described pipe that goes back on defense is weldingly fixed on flue outer wall, is provided with sampling gun in the pipe that goes back on defense.
Further, operation valve is provided with between described pressure transfering appts and cyclone separator.
Further, described sampling gun extension elongation is less than the width of flue 1/3rd.
The utility model has following beneficial effect:
1. pair advance and retreat only valve seal, prevents sampler from leaking, ensures the degree of accuracy measured.
2. adopt welding manner, sampler is stablized, and can not rock, and ensures that job safety is reliable.
3. spacing ring ensures that advance and retreat stop valve and the pipe that goes back on defense stretches oversize, causes the disconnection of sampling gun and operation valve.
Accompanying drawing explanation
Fig. 1 is the utility model one-piece construction figure.
Fig. 2 is only valve seal structural drawing of retreating.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As illustrated in fig. 1 and 2, spiral-flow type fly ash constant speed sampler, pressurized air mouth 5 right-hand member of sampler is provided with tensimeter 4, the right-hand member of tensimeter 4 connects pressure transfering appts 6, be connected with cyclone separator 2 below pressure transfering appts 6, sampling jar 1 is provided with below cyclone separator 2, described pressure transfering appts 6 is all provided with cyclone separator 2 right-hand member and samples operation valve 3, the right-hand member of sampling operation valve 3 is provided with only valve 7 of retreating, described advance and retreat are stopped valve 7 and are located at and go back on defense on pipe 15, its left end is provided with packing ring 11, the left end laminating rubber ring 12 of packing ring 11, be provided with packing_seal 13 going back on defense outside pipe 15, be provided with valve outside packing_seal 13 and mend core 14, described sampling operation valve 3 and go back on defense between pipe 15 and be provided with retaining spacing ring 10, the described pipe 15 that goes back on defense is weldingly fixed on flue 8 outer wall, is provided with sampling gun in the pipe 15 that goes back on defense, operation valve is provided with between described pressure transfering appts 6 and cyclone separator 2, described sampling gun extension elongation is less than the width of flue 1/8th three.
Flue 8 is opened 2 holes, and the pipe 15 that will go back on defense is fixedly welded on flue outer wall, and the pipe 15 that will go back on defense is tightened with only valve 7 of retreating and guaranteed to seal, and is penetrated by sampling gun and goes back on defense in pipe 15, and stretch in flue, make sampling muzzle aim at flue gas and carry out flow path direction.During sampling, advance sampling gun, open the gas admittance valve near pressurized air mouth 5, regulate sampling operation valve 3, pressurized air pressure-vaccum closed each valve after 1-2 minute, took off sampling jar 1.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
