On the basis of simple operation and low use cost, the sampling method meets the sampling requirements for real time, accuracy and safety.
Description
Technical field
The present invention relates to steel industry thermal technology, environmental protection tests field, be specifically related to bladders sampler and sampling method.
Background technology
There is the existing century-old history that in the artificial sample method of utilizing the single head bladders to get gas, because it is easy and simple to handle, easy to carry, use cost is cheap, still is widely used in the coal gas in steel industry, combustion product gases and the special gas sampling analysis at present.But the single head bladders is got the gas method and in use had following defective: 1. sample time, (accomplishing a bladders samples the needed time) was longer, because bladders is single air intake opening (gas outlet) setting; For getting rid of the influence of residual gas, must carry out the bladders self-cleaning before gathering, i.e. bladders sampling is full of, emptying; General self-cleaning number of times is more than 4 times; For the high-purity test, wash number is more, causes sample time more than 3min; 2. real-time is relatively poor, because the uncertainty of sample time causes under the fluctuation of operating conditions condition, sampling is representative poor in real time; 3. have potential safety hazard, for, the harmful gas poisonous for coal gas etc., there is the possibility of detonation, poisoning at the scene in the Rapid Cleaning discharge process in bladders, threatens the person and device security; 4. the deaeration influence of bringing at all, because the single head bladders is connecing gas moment, air intake opening and atmosphere cause air to bring into, influence sampling precision, especially as far as high-pure gas.
Summary of the invention
The object of the present invention is to provide bladders sampler and sampling method, on basis easy and simple to handle, that use cost is cheap, accomplish short, real-time, no potential safety hazard sample time, satisfy on-the-spot convenient, real-time, accurate, safe sampling requirement.
To achieve these goals, the technical scheme of the present invention's employing is:
Said bladders sampler adopts the double end bladders to realize getting gas fast, and assurance air inlet and exhaust are accomplished simultaneously in the process of bladders self-cleaning, stop to bring into air.
Said bladders sampler; Comprise flue, be located at the sampling rifle in flue cross section, the force (forcing) pump of bleeding that is connected with the sampling rifle; The inlet manifold that is connected with the force (forcing) pump of bleeding; The bladders that is connected with inlet manifold, the discharge header that is connected with bladders, and be connected with discharge header and reach body of wall gas production flexible pipe outward.
Said bladders is divided into first bladders and second bladders, and said first bladders and second bladders are connected with said inlet manifold with parallel way one side, and opposite side is connected with said discharge header.
Said inlet manifold is connected through the gas production flexible pipe with the force (forcing) pump of bleeding, and is provided with first stop valve being used to connect on the gas production flexible pipe of the two.
Said first bladders and second bladders are connected through the gas production flexible pipe with said inlet manifold, are provided with second stop valve being used to connect on the gas production flexible pipe of the two.
Said discharge header is connected through the gas production flexible pipe with said first bladders and second bladders, is provided with the 3rd stop valve being used to connect on the gas production flexible pipe of the two.
Be provided with the 4th stop valve being connected with discharge header and reaching on the gas production flexible pipe outside the body of wall.
The connection that said second stop valve and the 3rd stop valve are realized said first bladders and second bladders and inlet manifold and discharge header with separate, be used to control the intake and exhaust of said first bladders and second bladders.
Said first stop valve and the 4th stop valve are used to adjust said first bladders and the second bladders admission pressure.
Utilize the sampling method of said bladders sampler, may further comprise the steps:
(1) connects said each parts of bladders sampler by process chart; Open first stop valve, second stop valve, the 3rd stop valve and the 4th stop valve; Start the force (forcing) pump of bleeding, adjust first stop valve and the 4th stop valve aperture, guarantee that first bladders and second bladders are in swelling state; This up-to-date style gas is dispensed to first bladders and second bladders after inlet manifold is mixed, converge, drain into the safety zone outward through discharge header again; After general 3 minutes, the residual gas in the device is excluded, and the gas that flows in the device is consistent with the interior gas of flue, and first bladders and second bladders begin sampling;
(2) second stop valve and the 3rd stop valve of closing control first bladders turnover gas unload first bladders, and seal first bladders with spring caliper, and sampling is for the first time accomplished;
(3) load onto the first subsequent use bladders and open corresponding second stop valve and the 3rd stop valve again; By the sampling period requirement, second stop valve and the 3rd stop valve of closing control second bladders turnover gas unload second bladders, and seal second bladders with spring caliper, and sampling is for the second time accomplished; Again load onto the second subsequent use bladders and open corresponding second stop valve and the 3rd stop valve;
(4) repeating step (2), (3), so back and forth, until satisfying sampling requirement.
As further improvement; Utilize the sampling method of said bladders sampler; In the sampling period is in 10 minutes the time, and said step (1) adopts two above bladders parallel connection arrangements, i.e. a plurality of balloon courages of getting of parallelly connected layout between inlet manifold and discharge header; According to the sampling period requirement, cut off the turnover gas stop valve of the bladders of respectively taking a sample.
As further improvement; Utilize the sampling method of said bladders sampler, when the sampling period surpassed 10 minutes, said step (1) was controlled the force (forcing) pump start and stop of bleeding through the Long-distance Control means; Promptly before sampling, start the force (forcing) pump of bleeding; Accomplish the cleaning and the sampling work of the quick collector of bladders, after bladders sampling completion, subsequent use bladders install, stop the force (forcing) pump of bleeding.So back and forth, until satisfying sampling requirement.
Because air inflow is bigger under many bladders parallel connection arrangements, should the bigger force (forcing) pump of bleeding of selection pressure flow, maximum flow is greater than 15l/min, and maximum output pressure guarantees that greater than 100kpa sampling pressure can satisfy the requirement of bladders sampling.
The invention has the advantages that: the present invention adopts the mode of two bladders samplings, and bladders keeps barotropic state always, and the phenomenon that does not exist air to bleed does not need the repetition self-cleaning, and the sampling period behind the employing double end bladders practices thrift 85% than single head bladders sampling method.Simultaneously, system adopts many bladders parallel connection arrangements, guarantees the real-time of sampling; , harmful gas poisonous in order to prevent threatens potential safety hazards such as the person, equipment, and gas outlet is extended to the safety zone discharging.The present invention accomplishes short, real-time, no potential safety hazard of sampling period, satisfies on-the-spot convenient, real-time, accurate, safe sampling requirement on basis easy and simple to handle, that use cost is cheap.
