Description
Technical field
The utility model belongs to economizer sampling anti-blocking technology field, and in particular to low-level (stack-gas) economizer differential pressure measuring point probe tube
Road anti-block apparatus.
Background technique
Low-level (stack-gas) economizer differential pressure measuring point sampling line original, which is designed as coming out in sample tap, in the prior art an anti-blocking sampling
Device, but in the process of running, since low province's differential pressure probe tube internal-external temperature difference is big, easy condensed water, flue gas are mingled with dust stratification in probe tube
Water is met easily in tube wall incrustation, sampling line is caused to block, measurement is inaccurate.Commonly anti-blocking is only installed to take on original sampling line
Sample device (sampler of built-in three layers of anti-jamming mechanism of vase-shaped), though there are some effects on block-proof pressure-taking, not it is obvious that also
It is often to cause blockages.There is still a need for compressed air from pipe fitting from pipeline is purged, to be cut when fouling is serious
Pipeline before sampler is opened, serious fouling is handled, also needs to weld it after the completion of processing, causes maintenance not
Just, it takes time and effort.
Summary of the invention
The utility model provides low-level (stack-gas) economizer differential pressure measuring point sampling line anti-block apparatus, keeps measuring point anti-blocking, and measured value
True and accurate.
The technical solution of the utility model is: low-level (stack-gas) economizer differential pressure measuring point sampling line anti-block apparatus, including low temperature saves
The sampling line of low-level (stack-gas) economizer two sides is arranged in coal device, the compensation wind being fixedly connected with sampling line by connecting flange
Pressure measurement anti-clogging, the blower of compensated wind-pressure measuring anti-clogging include sampling bridge breaker and anti-blocking purging device,
The sampling bridge breaker passes through scavenging pipeline respectively and connect with anti-blocking purging device, is connect by sample tracheae with transmitter, the change
It send to be equipped between device and sample tracheae and samples primary door.
Further, the anti-blocking purging device includes gas source, intake valve, filtering pressure regulator valve and flow controller to scheme.
Further, the filtering pressure regulator valve and flow controller are arranged in cabinet scheme.
Scheme further, offers detection hole on the cabinet, bypass duct, the side are connected in the detection hole
Road pipeline is connect with sample tracheae, and setting is before sampling primary door.
The utility model has the advantages that: the anti-blocking purging device of the utility model utilizes hydromechanical dynamic pressure compensation method, very
Reflect the pressure value of each measuring point online on the spot；The pressure of the utility model purging is greater than tested pressure, thoroughly solves more powder
The blocking on pressure measuring tube road and phenomenon is burnt under dirt and the condition of high temperature；Using voltage regulating and stabilizing device, the gas that power plant can be provided
Source carries out pressure stabilizing, it is ensured that the stabilization of flow controller output flow, and prolonged reliability service can be reached；It is not required to carry out artificial
Purging, significantly reduces the labor intensity of worker；The road Xiang Neimei is equipped with by-pass switch, in closing shape when equipment operates normally
State, put into operation after the equipment installation for the first time or blowing out after open the switch and can remove the sundries such as rubbish in pipeline when turning back on, such as
By-pass switch need to be opened, it is necessary to first close the needle stop valve on transmitter sampling line；It is needed if manually overhauling if necessary,
By disassembly flange can censored sample device to the pipeline between pressure port, it is convenient and efficient.
