Abstract
The invention discloses a cluster type fluid sampling device. The sampling device is rows of cluster type structures on a whole; sampling ends of sampling pipes of different length are distributed in equidistance, and the sampling pipes are fixed on a fixed plate; one end of a connecting flexible pipe is connected with one sampling pipe through a connector, and the other end of the connecting flexible pipe is connected with a sampling mixer. The internal diameter of the sampling pipes is identical with that of the connecting flexible pipes, and the length of each sampling pipe is equal to that of one connecting flexible pipe matching with the sampling pipe. The rigid sampling pipes are inserted into a pipeline in a sampling cross section, and the connecting flexible pipes convey a fluid sample extracted by the sampling pipes to the sampling mixer in virtue of pressure difference. The sampling device enables real-time and validity of acquisition of fluid samples at different position to be realized by using the principle of resistance-matching balance and realizes the goal of full cross section uniform arrangement and multi-point, equi-velocity and simultaneous sampling of a sampling pipeline to be measured.
Description
Technical field
The present invention relates to a kind of sampler, refer in particular to the cluster type fluid sampling apparatus that the uneven polycomponent gas-solid of component distributing, stream-liquid two-phase flow body are carried out uniform sampling.
Background technology
At present, all exist in a lot of industrial processs single component in the industrial pipeline or multicomponent gas and gas and solid particle mixture, single component or multi-component liquid and liquid and the difficult problem of solid particle mixture uniform sampling.Because receive the influence that component substances characteristic, composition mixed characteristic, industrial pipeline layout and technological process change, the unevenness that fluid (gas, liquid) composition, solid particle distribute on room and time has caused the difficulty of these fluid-mixings being carried out representative sampling.Such as, the boiler furnace of large-scale coal-fired power plant is huge, the mixing of fuel and combustion air, burning; There is sizable unevenness in the after-flame process, because flue gas flow is short, and the flue enormous size; Mixed process is not enough; The smoke components lamination problem is outstanding, adds the bleed existence of cold air and a large amount of soot particles of flue wall, and there is the serious irregular situation of flue gas concentration field distribution in individual areas in the flue.For safety, economy, the cleanliness that improves combustion process, need carry out Measurement and analysis accurately to smoke components, be used for rational evaluation, control boiler combustion process.Consider above-mentioned actual conditions; Realize smoke components is accurately measured; Prerequisite is must obtain to have quite representational smoke components; And to accomplish this point, must adopt the uniform sampling simultaneously of total cross-section multipoint method to whole tested flue cross section, but this has sizable difficulty in practical operation.Sampler and the method used at present mainly contain flue list stopple coupon pointwise sampling method and bourdon's tube total cross-section sampling method, still all have limitation, can not realize simultaneously the requirement to the flue gas uniform sampling of total cross-section different parts.Therefore; In order better the flue gas total cross-section to be taken a sample at one time, guarantee samples' representativeness, need a kind of novel sampling apparatus of development; Make sampled point can realize as requested that total cross-section evenly arranges, each sampled point sample size of gathering equates or flow collection such as title simultaneously.Then, the medium appearance that collects is transported to the sample mix device, evenly mixes and analysis to measure.
Summary of the invention
The technical matters that the present invention will solve provides a kind of cluster type fluid sampling apparatus; This is meant the uneven polycomponent gas-solid of component distributing, stream-liquid two-phase flow body and device that the uneven fluid media (medium) of distribution of concentration is carried out uniform sampling; This device not only has evenly to be arranged tested sampling pipe total cross-section; Multiple spot, uniform flow, the ability of sampling simultaneously, but also possess the ability that independent sampling is carried out in sampling arbitrfary point, cross section.
The technical matters that the present invention will solve is realized by following structure: a kind of cluster type fluid sampling apparatus; Comprise stopple coupon, shaft collar, connector, connection flexible pipe; It is characterized in that: sampler is whole to be several rows of cluster type structure, and the sampling termination of different length stopple coupon is equidistant structure distribution, and stopple coupon is fixed on the shaft collar; Connect flexible pipe one end and be connected with stopple coupon through connector, the other end connects the sampling mixer.
The present invention also comprises following structure: stopple coupon is identical with the internal diameter that connects flexible pipe, every stopple coupon with equate with the closing all of hose length that be connected of its coupling.This can realize every stopple coupon of sampler has been carried out the compensation of resistance to flow, finally reaches under the equal suction force situation, and it is identical or close to satisfy the interior air flow rate of every stopple coupon, realizes the uniform sampling to different stopple coupons sampling end fluids.
Principle of work of the present invention: according to the size in tested pipeline cross section; On the cross section, evenly arrange this cluster type fluid sampling apparatus; Sampler has many stopple coupons; Every stopple coupon divides two parts, and a part is the ducted stopple coupon in cross section of taking a sample that extend into of rigidity, and a part is flexible connection flexible pipe.Flexibly connect flexible pipe the fluid sample that the rigidity stopple coupon extracts is transported to the sampling mixer.Because it is different that the rigidity stopple coupon extend into the measured medium pipeline location; The length of each stopple coupon is also different; Identical or close in order to guarantee resistance from sample tap to the sampling mixer; Length is different to the stopple coupon of different length coupling internal diameter is identical flexibly connects flexible pipe, can be so that the total length that flexibly connects flexible pipe that every stopple coupon adds coupling is identical.Through flexibly connecting flexible pipe each stopple coupon is compensated along the journey resistance to flow, under the situation of same suction force, can realize the evenly equal purpose of Fluid Volume that each stopple coupon is extracted.
The present invention has following advantage: the cluster type fluid sampling apparatus is simple in structure, and is cheap, avoided the flow measurement and the regulating device of expensive.But sampler integral demounting; Carry, use, easy to maintenance; Adopt the impedance match equilibrium principle to realize real-time and the validity that the diverse location fluid sample is gathered, realized tested sampling pipe total cross-section is evenly arranged, multiple spot, uniform flow, the purpose of sampling simultaneously.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.As shown in Figure 1, this sampler integral body is several rows of cluster type structure, by stopple coupon 1, and shaft collar 2, connector 3 connects flexible pipe 4 several main parts and forms.The sampling termination of different length stopple coupon 1 is equidistant structure distribution, and stopple coupon 1 is fixed on the shaft collar 2, connects flexible pipe 4 one ends and is connected with stopple coupon 1 through connector 3, and the other end connects the sampling mixer.Stopple coupon 1 is identical with the internal diameter that connects flexible pipe 4, every stopple coupon 1 with equate with the closing all of flexible pipe 4 length that be connected of its coupling.Ducted fluid is extracted in the end of the stopple coupon 1 of different sample position; Fluid is extracted out through stopple coupon 1, connector 3, connection flexible pipe 4 respectively; Get into and get into the fluid ingredient analytical appearance again after the fluid sampling mixer evenly mixes, realize uniform sampling diverse location fluid in the pipeline.
