Description
Technical field
The present invention relates to detection device fields, in particular to a kind of to judge gas piping internal water accumulation by radar level gauge
Device.
Background technique
Pipeline is connected into pipe, pipe connector and valve etc. for conveying gas, liquid or with solid particle
Fluid device, gas piping is the pipeline for transporting coal gas, and be laid in underground mostly, and town gas pipe network is like city
" blood vessels " in city ensure that the safe operation of pipe network is most important, have preferable conveying effect, and lower production costs, extensively
Applied to every field；However the gas distributing system used at this stage has nine sets of gas cleaning systems, although what is be all made of is absolutely dry
Method dedusting technology, but the water vapour that moisture of the blast furnace in smelting process in raw material is formed under high temperature action is with coal gas gas
Stream enters in gas piping, and coal gas is easily generated since the reduction of own temperature and coal gas encounter cold tube wall during transportation
A large amount of condensed waters are deposited on duct bottom, to gas piping containing harmful substances such as gas ash, acidic chemical objects in condensed water
Very big harm is caused, with the condensed water in discharge line but also can be not only discharged although having passed through and being provided in gas piping
The coal gas drainer of the impurity such as gas ash in pipeline, but can not reliably judge in pipeline whether ponding, especially in cold
Winter, by the interference of the excessive phenomenon of steam condensate (SC), the problem of cannot finding gas piping internal water accumulation in time, in order to guarantee coal
The normal operation of gas water trap, it will usually be passed through steam in coal gas drainer and be kept the temperature, a large amount of steam condensed water is from coal
Overflow pipe in gas water trap is excessive, and usually judging the mode of water trap whether normal operation is exactly to observe whether overflow pipe overflows
Stream is considered as normally if overflow, blocks if there is one secondary valve of water trap, and coal gas drainer also overflow is normal, operation
Personnel are difficult to judge water trap failure, it is easy to a large amount of condensed water of accumulation in gas piping is caused, it is big due to condensed water
Amount accumulation exacerbates the corrosion of inner wall of the pipe, be easy to cause gas pressure fluctuation to generate " tidal bore ", is formed when serious at low-lying place
Water seal causes coal gas to interrupt, and jeopardizes the safety in production of subsequent user, or even causes that pipeline bearing load is excessive and is broken, collapses,
Cause pernicious coal gas accident, and inside of gas pipeline invisibility, lead to not correctly judge inside whether ponding, due to coal
The 45# steel that the material of feed channel is generally selected is made, and intrinsic opaque characteristic determines in gas piping not
Visibility, only according to naked eyes cannot judge in pipeline whether ponding, can only judge with the experience of operations staff, judgement not in time,
Inaccuracy cannot judge one secondary valve failure of coal gas drainer when by steam condensate (SC) excessive interference in time, because it is found that
Not in time, a large amount of ponding in gas piping are easy to appear, the safe operation of gas piping is influenced, for this purpose, we have introduced one kind
The device of gas piping internal water accumulation is judged by radar level gauge, can accurately be judged existing with the presence or absence of ponding in gas piping
As.
