Abstract

The utility model relates to a fixed fly ash sampler capable of regulating fly ash quantity. The fixed fly ash sampler comprises a fly ash sampling head, a communicating tube, a sampling tank, a regulating valve and a fly ash recycling tank, wherein the communicating tube is fixedly connected with the fly ash sampling head, the sampling tank is detachably connected with the communicating tube, the regulating valve is arranged in the communicating tube, and the fly ash recycling tank is connected with the communicating tube through a collecting tube; an opening of the collecting tube is formed in the communicating tube and is positioned in the upper end of the regulating valve, and a fly ash discharging valve is arranged at the lower end of the fly ash recycling tank. The fixed fly ash sampler has the advantages that the operation is simple, and the use is convenient; the representativeness of a collected fly ash sample can be increased, and the error of the carbon content of the fly ash sample of a boiler can be reduced; the environmental pollution is reduced, and the fixed fly ash sampler has a certain environment-friendly effect.

Description

A kind of fixed fly ash sampler of adjustable flying dust amount
Technical field
The utility model relates to a kind of station boiler fly ash sampling equipment, specifically a kind of fixed fly ash sampler of adjustable flying dust amount.
Background technology
Fly ash sampler is the vitals that station boiler is measured boiler efficiency, and its effect is for gathering flying dust sample, then gathered flying dust sample being carried out the chemical examination of unburned carbon in flue dust, for anti-EQUILIBRIUM CALCULATION FOR PROCESS boiler efficiency.The height of anti-EQUILIBRIUM CALCULATION FOR PROCESS boiler efficiency depends mainly on boiler exhaust gas thermal loss and heat loss due to combustibles in refuse.The size of heat loss due to combustibles in refuse is mainly that the height of boiler flyash carbon content determines.The accuracy of boiler flyash carbon content depends primarily on the representativeness that fly ash sampler gathers flying dust sample.
At present station boiler fixedly fly ash sampler generally adopt traditional impact type fly ash sampler, the problem that exists the institute's flying dust sample that gathers representativeness to differ from actual application.The flying dust amount of boiler changes with the variation of boiler load and coal-fired ash, general 8 hours of Fly ash sampling cycle, the flying dust amount of traditional impact type fly ash sampler collection can not be controlled, and may cause fly ash sampler in the sample period, to gather collection capacity problem very little in full or the sample period being less than.When occurring that sampler is being less than, gathering tank completely time in 8 hours, is not the flying dust of whole acquisition time section by causing the flying dust of collection, thereby causes the flying dust sample that gathers representative poor; When occurring that in the sample period, collection capacity very little, can not meet the problem of unburned carbon in flue dust assay.Therefore, be necessary that the fixed fly ash sampler of developing a kind of adjustable flying dust amount addresses the above problem.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fixed fly ash sampler of adjustable flying dust amount simple in structure, easy to use.
The technical scheme that the utility model solves its technical matters employing is: a kind of fixed fly ash sampler of adjustable flying dust amount, it comprise Fly ash sampling head, the communicating pipe being fixedly connected with Fly ash sampling head, with the sampling jar removably connecting communicating pipe, be arranged on variable valve in communicating pipe, with the flying dust recycling can being connected by collection tube communicating pipe, described collection tube is opened on communicating pipe and is positioned at variable valve upper end, and described flying dust recycling can lower end arranges fly ash emission valve.
Good effect of the present utility model is: by variable valve, regulate the flying dust amount that enters sampling jar, all the other enter flying dust holding tank from the flying dust of Fly ash sampling head collection, guaranteed that flying dust can continue to enter sampling jar within a sample period, and can avoid Fly ash sampling tank tank full; The internal diameter of communicating pipe and Fly ash sampling head is 40mm--50mm, is greater than communicating pipe and the Fly ash sampling head internal diameter of common impact type fly ash sampler, guarantees that the ash amount that enters fly ash sampler enough provides detection; In the time of can avoiding occurring that Fly ash sampling tank tank is full, in the pipeline of sampling jar top, there is a large amount of flying dusts, the pollution of flying dust diffusion couple environment during the lower sampling jar of dismounting.Adopt the utility model:
1) simple to operate, easy to use; 2) can improve the representativeness that gathers flying dust sample, reduce the error that gathers boiler fly ash sample unburned carbon in flue dust; 3) reduce contaminated environment, there is certain environmental protection effect.
Accompanying drawing explanation
Structural representation when Fig. 1 is the utility model work;
In accompanying drawing, 1 Fly ash sampling head, 2 communicating pipes, 3 boiler flues, 4 collection tubes, 5 sampling jars, 6 flying dust recycling cans, 7 variable valve, 8 fly ash emission valves.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described further.
As shown in Figure 1, the fixed fly ash sampler of a kind of adjustable flying dust amount of the present embodiment, it comprise Fly ash sampling head 1, the communicating pipe 2 being fixedly connected with Fly ash sampling head 1, with the sampling jar 5 being threaded communicating pipe 2, be arranged on variable valve 7 in communicating pipe 2, with the flying dust recycling can 6 being connected by collection tube 4 communicating pipe 2, described collection tube 4 is opened on communicating pipe 2 and is positioned at variable valve 7 upper ends, and described flying dust recycling can 6 lower ends arrange fly ash emission valve 8.
Described Fly ash sampling head 1 head is wedge shape, and its inclined-plane is relative with the interior flow of flue gas direction of boiler flue 3 (Fig. 1 direction of arrow).
Connected mode between the utility model communicating pipe and communicating pipe also can be selected clamping.
The course of work of the present embodiment is: Fly ash sampling head 1 is inserted in boiler flue 3, according to the flying dust generation in boiler, adjust the switching degree of variable valve 7, a flying dust part of controlling in communicating pipe 2 enters sampling jar 5, the unnecessary flying dust recycling can 6 that enters, can continue to collect the flying dust sample of enough analytical tests to realize within a sample period (8 hours) sampling jar 5.And by the adjusting of flying dust amount, improve the representativeness of the flying dust of fly ash sampler collection, reduce the error of the unburned carbon in flue dust that gathers.
After a sample period completes, close variable valve 7, the lower sampling jar 5 of dismounting, gathers natural subsidence and arrives the flying dust sample in sampling jar 5, then the flying dust sample gathering is detected to chemical examination; Open fly ash emission valve 8, the flying dust in flying dust recycling can 6 is discharged, flying dust enters environment-friendly processing unit or gathering-device, the environmental protection treatment before discharging in the lump with flying dust in boiler.
After sampling, close fly ash emission valve, again install sampling jar, open variable valve, the sampling that enters next cycle detects.
Sample period of the present utility model can be set as 8-24 hour according to concrete testing requirement, then according to the flying dust amount in boiler, regulates the aperture of variable valve.
