Abstract
The invention relates to a water-cooled wall chemical cleaning monitoring tube which comprises a PVC upper tube with an upward opening and a vertically downward PVC lower tube. The PVC upper tube is connected with the PVC lower tube through a PVC inclined tube, a thermometer sleeve is arranged on the outer side of the upper wall of the PVC inclined tube, and a tube upper valve, a tube upper flange, a tube lower valve and a tube lower flange are sequentially installed on the PVC lower tube from top to bottom. According to the monitoring tube, the cleaning situation of a furnace body can be reflected well, the cleaning condition can be observed at any time, an indicating piece is hung on the position of the lower flange, the possibility is provided for calculating a corrosion rate closer to the actual corrosion rate of the system, a thermometer is arranged in the thermometer sleeve, and therefore the temperature of cleaning fluid is monitored at any time and temperature measurement errors of an original infrared thermometer are eliminated.
Description
Technical field
The invention belongs to the chemical cleaning in power plant technical field, particularly a kind of water-cooling wall Chemical cleaning monitor tube.
Background technology
Use water as the cooling medium of turbine discharge at chemistry, two kinds of water systems are arranged usually: the single flow cooling water system circulating cooling water system of unifying; The latter is divided into again Enclosed Type Circulating Cooling Water System and open-type cooling water system.This system cools water is in recycling process, and not only temperature raises, and the problems such as fouling, corrosion and growth of microorganism are arranged, so on-the-spot in service need to the cleaning circulation.
In Chemical cleaning, monitor tube all is arranged on circulating-pump outlet at present, can not well reflect that internal system cleans situation, therefore develops a kind ofly to reflect that internal system cleans the device of situation and seem very necessary.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of water-cooling wall Chemical cleaning monitor tube is provided.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of water-cooling wall Chemical cleaning monitor tube, comprise the PVC upper pipe of opening upwards and PVC lower pipeline straight down, between the pipeline of PVC top and the bottom, by the PVC inclined tube, connected, be shaped with the thermometer sleeve in the oblique upper wall of the PVC inclined tube outside, valve on pipeline, pipeline upper flange, pipeline lower valve and pipeline lower flange from top to bottom are installed successively on the PVC lower pipeline.
And the included angle A between described PVC inclined tube and PVC upper pipe is: 90 degree<A<120 degree.
And the pipe diameter that described PVC upper pipe, PVC lower pipeline and PVC inclined tube adopt is consistent, the diameter of described upper pipe is determined by the circulating-pump outlet diameter connected with it.
And, be shaped with outwardly directed hook at described lower flange outer ledge, hang with indicating piece on described hook.
Advantage of the present invention and good effect are
1, monitor tube of the present invention can well reflect that furnace body cleans situation, can take at any time monitor tube apart, observes to clean and carries out situation; Can hang with indicating piece at the ring flange place, after cleaning finishes, with this indicating piece, calculate corrosion rate, more approach the true corrosion rate of system.
2, the present invention is provided with valve on monitor tube, can sample at any time, and sample point is more representative, and monitor tube is provided with the thermometer sleeve, can insert thermometer monitoring rinse liquid temperature, has overcome the error of the temperature of infrared radiation thermometer measurement in the past.
The accompanying drawing explanation
Fig. 1 is the topology view of monitor tube of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of water-cooling wall Chemical cleaning monitor tube, as shown in Figure 1, comprise the PVC upper pipe 1 of opening upwards and PVC lower pipeline 4 straight down, between the pipeline of PVC top and the bottom, by PVC inclined tube 3, connected, be shaped with thermometer sleeve 2 in the oblique upper wall of the PVC inclined tube outside, valve 5 on pipeline, pipeline upper flange 6, pipeline lower valve 7 and pipeline lower flange 8 from top to bottom are installed successively on the PVC lower pipeline.
In specific embodiment of the invention, included angle A between described PVC inclined tube and PVC upper pipe is: 90 degree<A<120 degree, the pipe diameter that described PVC upper pipe, PVC lower pipeline and PVC inclined tube adopt is consistent, and the diameter of described upper pipe is determined by the circulating-pump outlet diameter connected with it.
In specific embodiment of the invention, be shaped with outwardly directed hook 9 at described lower flange outer ledge, hang with indicating piece 10 on described hook.
Operation principle
Owing to being provided with two flanges on monitor tube of the present invention, at the ring flange upper and lower side, valve all is housed, so can block at any time monitor tube, in Process of Chemical Cleaning, dismantle, observe to clean and carry out situation, hang indicating piece by be shaped with outwardly directed hook at the ring flange outer ledge, after cleaning finishes, with this indicating piece, calculate corrosion rate, more approach the true corrosion rate of system.In addition, the thermometer sleeve, can insert thermometer monitoring rinse liquid temperature, overcome the error of the temperature of infrared radiation thermometer measurement in the past.
