Description
Technical field
This utility model relates to a kind of Rear of Utility Boiler flue square-section flue gas measurement apparatus, belongs to boiler smoke sampling
Field of measuring technique.
Background technology
During power boiler burning, in stove, burning is the important indicator of boiler implosion, produces in combustion in flue gas
The oxygen of life, carbon monoxide, carbon dioxide, nitrogen oxides, sulfur dioxide are all important Monitoring Data, particularly boiler efficiency
Calculating, air leak rate of air preheater calculating, discharge value etc. are required for smoke components accurately.Under additional overall situation environmental requirement,
Measuring the most accurately, controlling smoke components is the important evidence that energy saving for power plants reduces discharging.
At present all clear stipulaties, generating set afterbody cigarette in the standard GB/T-10184-88 of China and in industry standard
Measuring smoke components on road must use gridding method layout measuring point to measure, and how to carry out gridding method synchro measure the most increasingly
Have higher requirement.Modern thermal power plant monoblock is increasing, and unit scale is big, flue is deep and wider employing net
The measuring point that lattice method is arranged is more, and current existing flue gas sampler is all with single piece of metal pipe successively sampling method.The method needs people
Work manually carries out the location of different depth successively and samples multiple measuring points, and Large-scale machine set flue is big and measuring point is more, one
Data must be weighted averagely more greatly by gridding method used time of getting off, during sampling and require that the set steady time is longer, Er Qiesuo
The data gathered are that to complete within a Δ t time is not that instantaneous value representativeness is poor.This measuring method is to survey crew
Labor intensity data relatively big, the longest, that measure are to sample each point on grid successively in Δ t, and can not be real
Flow instantaneous sampling is waited in the most all sites simultaneously, and the method brings the problems such as big, the operation inconvenience of workload, has a strong impact on measurement essence
Degree and representativeness are poor.
Summary of the invention
The purpose of this utility model is, in order to realize the flow synchronized samplings such as boiler of power plant square-section multichannel, again can
Independent measuring point is carried out sampling functions, it is provided that a kind of Rear of Utility Boiler flue square-section flue gas measurement apparatus.
This utility model has technical scheme as follows: a kind of Rear of Utility Boiler flue square-section flue gas measurement apparatus includes
The multi-functional sampling gun of multitube, suspended body flowmeter and flue gas analyzer.The sampling end of multi-functional sampling gun inserts afterbody rectangle cigarette
Road；The outfan of multi-functional sampling gun connects suspended body flowmeter by flue；Again through the flow-control of suspended body flowmeter
Switch connects flue gas analyzer.
The multi-functional sampling gun of described multitube is the probe tube of the steel pipe composition of many different lengths, and center sleeve is equipped with same
Steel pipe quantity and the equal thermocouple of length, can meet smoke sampling and thermometry requirements simultaneously.
Described float-type is calculated as multiple independent float-type unit and combines, and each unit all has a flow control
System switch and flow indicate float, carry out Flow-rate adjustment for tester.
Described flue gas analyzer is existing measuring instrument, is the analytical tool of a kind of band suction pump, such as assembled unit relatively
It is contemplated that the air pump installing a big power in front of an analyser additional meets requirement of bleeding in the case of many flue gas flows are relatively big.
The beneficial effects of the utility model are, this utility model before the test according to square-section size by equal for all measuring points
Installing the multi-functional sampling gun of multitube with size, every sampling steel pipe is connected with suspended body flowmeter unit by flexible pipe.Each
Suspended body flowmeter unit outlet threeway is connected on a thicker flexible pipe, then is connected with flue gas analyzer, thus realizes
The flow instantaneous such as single channel multiple-unit synchronization are measured.Work when can greatly reduce measurement by installing measurement apparatus in advance
Intensity it is crucial that achieve the flow synchro measures such as multiple spot, improve certainty of measurement be truly realized GB GB10184-88 want
The grid survey purpose asked.Measure especially for air-heater leakage, the real import and export total cross-section that achieves synchronizes
Measure, reduce discharging providing reference frame for power plant for energy conservation.
Accompanying drawing explanation
Fig. 1 is this utility model flue square-section flue gas measurement apparatus structural representation；
In figure, 1 is afterbody rectangular flue；2 is the multi-functional sampling gun of multitube；3 is suspended body flowmeter；4 is flow instruction
Float；5 is flue gas analyzer；6 is flow control switch.
Detailed description of the invention
Detailed description of the invention of the present utility model is as shown in Figure 1.
The present embodiment is achieved like this, and the present embodiment one Rear of Utility Boiler flue square-section flue gas measures dress
Put, including the multi-functional sampling gun of multitube 2, suspended body flowmeter 3, flue gas analyzer 5.
The multi-functional sampling gun of every multitube of the present embodiment is the size system of the square-section according to on-the-spot back-end ductwork 1
Produce a kind of sampling gun meeting the grid survey requirement of GB GB10184-88, measure steel pipe number and should meet now with measuring length
Requirement, simultaneously in the centre sleeve pipe of sampling gun equipped with sampling steel pipe with quantity and the equal thermocouple of length, with
Time meet smoke sampling and thermometry requirements.Float-type is calculated as multiple independent float-type unit and combines, each
