The utility model discloses can be balanced, constant speed ground gathers the flying dust sample, and then can accurately be reflected the parameter of the boiler actual motion condition.
Description
Technical field
The utility model relates to a kind of gas-particle two-phase sampler, particularly a kind of unpowered fly ash sampler.
Background technology
Boiler plant is in operation, and needs the flying dust continuous acquisition sample to pulverized coal channel, and then obtains real-time carbon content numerical value, for operation personnel provide information accurately and reliably, make boiler plant be in optimal operational condition as far as possible.Fly ash sampler for pulverized coal channel sampling of the prior art can not balanced, gather flying dust sample to constant speed, just can not obtain the parameter of reflection boiler practical operation situation exactly.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, a kind of unpowered fly ash sampler is proposed, this is unpowered fly ash sampler balanced, constant speed ground can gather flying dust sample, and then can obtain the parameter reflecting boiler practical operation situation exactly.
The technical problems to be solved in the utility model is achieved through the following technical solutions.The utility model is a kind of unpowered fly ash sampler, its feature is: comprise stopple coupon, along sampling mouth and the cyclone separator being located at stopple coupon tail end of stopple coupon axial distribution, cyclone separator bottom is provided with fly-ash collector, cyclone separator top is provided with fairlead, fairlead is connected with recirculatory pipe, the endpiece of described recirculatory pipe stretches in pulverized coal channel, the endpiece of recirculatory pipe is provided with Laval-cavity nozzle, described stopple coupon is provided with the static pressure transducer for detecting static balance, described stopple coupon and the junction of cyclone separator are provided with flue gas static pressure by-pass cock.
In a kind of unpowered fly ash sampler technical scheme of the utility model, preferred technical scheme feature is further: described sampling mouth vertically upward.
In a kind of unpowered fly ash sampler technical scheme of the utility model, preferred technical scheme feature is further: the quantity of described sampling mouth is at least 3.
In a kind of unpowered fly ash sampler technical scheme of the utility model, preferred technical scheme feature is further: described Laval-cavity nozzle is connected to trumpet-shaped outlet, and the miner diameter end of described outlet is connected with Laval-cavity nozzle.
In a kind of unpowered fly ash sampler technical scheme of the utility model, preferred technical scheme feature is further: described sampling mouth is inverted cone-shaped structure.
Compared with prior art, the utility model has following technique effect: the utility model sampling is without the need to suction power, coal dust from sampling mouth through stopple coupon to cyclone separator, a part is in coal ash collecting device, obtain collected specimens, all the other coal dusts are back in pulverized coal channel through fairlead, recirculatory pipe, thus prevent the waste of coal dust; By arranging the static pressure transducer for detecting static balance, before sampling, the pressure of flue and stopple coupon is measured, by flue gas static pressure by-pass cock, the pressure constant speed between flue and stopple coupon is regulated again, balanced, constant speed ground can gather flying dust sample, and then the parameter reflecting boiler practical operation situation can be obtained exactly like this; By arranging Laval-cavity nozzle, utilize the pressure reduction produced in atmospheric pressure and flue, will be withdrawn in flue without coal ash flue gas in cyclone separator rapidly, whole sampling process need additionally to increase propulsion system, and structure simply, uses convenient.
