Description
Technical field
The present invention relates to power plant stack gas to administer environment protection field, in particular to one kind open loop on titanium composite panel chimney wall is protected
Hole measuring method.
Background technique
Titanium composite panel (inner steel lining titanium, general titanium is with a thickness of 1.2mm) has good anti-corrosion effect, in China's thermal power generation
Factory has a large amount of titanium composite chimneys to be currently running.Since national environmental protection policy is more and more tighter, new standard and code requirement are increasingly
After height, especially minimum discharge policy implementation, newly-increased measuring point need to be needed on built titanium composite panel chimney or compares sampling hole
(gaging hole pipeline DN00 or so), is just able to satisfy code requirement.
Since titanium material can not be connect with steel plate (including steel alloy) by welding manner, titanium high temperature resistant only has 300 DEG C of left sides
The quality on the right side, temperature high titanium again will change, and the quality that common steel tube directly affects titanium is welded on titanium composite panel, thus
Influence its anti-corrosion effect.Chimney siding is routinely opened there are two types of measured hole methods: first is that the aperture on chimney, cleaning hole periphery lining
Titanium welds carbon steel measurement pipe and chimney wall carbon steel, titanium is then served as a contrast inside measurement pipe, then weld with chimney lining titanium, is formed
Obturator solves anti-corrosion.Second is that measurement pipe generally titanium, after chimney wall aperture, the titanium tube road and chimney titanium liner are welded
It connects, forms seal, solve anti-corrosion.
First method: due to gaging hole caliber very little, the requirement of titanium lined technique is high and very cumbersome, while when carbon steel welding
High temperature can damage titanium lined, influence chimney lining titanium total quality, carry out risk to anticorrosion belt.
Second method: titanium is relatively soft, and intensity is inadequate, can not the heavier measuring instrumentss of load；And titanium is expensive, sexual valence
It is higher than not；Construction is inconvenient, and titanium plate welding needs professional that could complete.
Therefore, a kind of material cheap, easy for construction is found, also wants to solve anti-corrosion with titanium interliner well
Technique is crucial.
Summary of the invention
The purpose of the present invention is to the above technical problems, provide one kind open loop on titanium composite panel chimney wall and protect gaging hole
Method, it is save the cost, easy for construction, and effectively solve etching problem.
Technical problem of the invention is mainly addressed by following technical proposals:
(1) material prepares: a root timber matter is 316L, diameter 100mm, length 300mm pipeline are as probe tube, mating
316L alloy flange 1, mating simple steel flange 2, mating blind plugging plate 1, mating bolt and each 8 totally 16, nut are mating
Polytetrafluoroethylene (PTFE) soft rubber gasket 2, alloy electrode is several；
(2) it will use to be fully welded with alloy electrode between measurement probe tube one end and alloy flange and connect；
(3) measurement probe tube installation site is chosen on titanium composite panel wall, opens measured hole, size with plasma cutting machine
For 110mm；
(4) by the jacketed polytetrafluoroethylene (PTFE) soft rubber gasket of the 316L probe tube of welding alloy flange, then from chimney
The probe tube is passed through measured hole by inner wall, that is, titanium liner side, and guarantees that inner wall of stack is close to alloy flange；
(5) apart from a conventional carbon steel flange is welded on the outside of chimney at siding 50mm on 316L probe tube, by single ended bolt
The simple steel flange is passed through against titanium composite flue outer wall, while covering top nut, fastening bolt and spiral shell in the another side screw rod of simple steel flange
Mother makes screw rod hold out against chimney exterior panel, and same method installs other screw bolt and nut；
(6) another simple steel flange is installed in the another side of 316L probe tube, at the same put on polytetrafluoroethylene (PTFE) soft rubber gasket and
Blind plugging plate, that is, be installed.
The beneficial effects of the present invention are: installation is simple, without special anticorrosion process is done again, without the welding (titanium in titanium plate
Welding needs special welder, and technique is more complex)；Materials are convenient, and material price is cheap, and weight bearing power is strong；It efficiently solves
The difficult point of measurement pipeline is installed in aperture additional on titanium composite panel, it is ensured that measurement pipeline and one closing of titanium liner formation are whole, solve
Etching problem after Wet chimney titanium composite panel aperture has and promotes applied value well.
