Abstract
The utility model discloses a kind of mist eliminator flushing pipeline leakage detection system, comprise flushing pipe and leakage detection apparatus, described flushing pipe comprises flushing jellyfish pipe, sparge water arm, sparge water valve; Described leakage detection apparatus is arranged on described sparge water arm, and described leakage detection apparatus comprises waste pipe and drain valve.The utility model can accurate positioning leakage valve, greatly saves the leak detection repair cycle, increases work efficiency.
Description
Technical field
The utility model belongs to technical field of flue gas desulfurization treatment, relates to a kind of mist eliminator flushing water lines leakage detection system.
Background technique
Demister is power plant's requisite critical elements when carrying out last stage flue gas desulfurization process, it is mainly for separating of the drop of gas entrained with in power plant absorption tower, to ensure mass-transfer efficiency, after reducing valuable loss of material and improving tower, the working environment of heat exchanger, reduces in tower corrosion-resistant process specifications simultaneously.Demister mainly comprises demister body and the rinse-system for carrying out shower operation to demister body.
As shown in Figure 1, this rinse-system flushing line simplicity of design, directly draw several the arms removed mist and rinse from rinsing jellyfish pipe 1, often arm is as a road sparge water, and arm 2 is flushed through valve 3 and controls for current mist eliminator flushing system.For Henan 2 × 660MW unit Shi Hui Shi ?gypsum wet mist separator of desulfurization, this mist eliminator flushing water system arranges 21 road arms.Because valve switch is frequent, pipe vibration can make valve actuator and valve rod zero drift.Owing to not designing leakage detection apparatus, leak detection work can only listen pin or instrument to judge by using during flushing of pipeline, but when leaking in a certain valve exists or leaking in the existence of several valve, due to female pipe racks pressure, all can there is current sound in interior fistulae road and adjacent tubes, leak in judging and have difficulties, leak detection degree of accuracy is had a greatly reduced quality.Check simultaneously, treatment cycle is longer, leak for a long time and reduce female pipe sparge water pressure on the one hand, cause mist eliminator flushing quality to decline, another aspect is leaked for a long time and is affected the water budget on absorption tower.
Model utility content
For the problems referred to above, the purpose of this utility model is to provide a kind of mist eliminator flushing water lines leakage detection system, can accurate positioning leakage valve, greatly saves the leak detection repair cycle, increases work efficiency.
For achieving the above object, the utility model is by the following technical solutions:
A kind of mist eliminator flushing pipeline leakage detection system, comprises flushing pipe and leakage detection apparatus, and described flushing pipe comprises flushing jellyfish pipe, sparge water arm, sparge water valve; Described leakage detection apparatus is arranged on described sparge water arm, and described leakage detection apparatus comprises waste pipe and drain valve.
Further, described flushing jellyfish pipe connects some described sparge water arms.
Further, described sparge water arm is controlled by described sparge water valve.
Further, described sparge water valve is electric valve or pneumatic valve.
Further, described waste pipe is identical with the material of described sparge water arm, is stainless steel.
Further, described waste pipe is connected on the pipeline of described rinse water valve described sparge water arm behind the door by welding manner.
Further, the pipeline wall thickness 0.6mm of described waste pipe, inner diameter is 11.5mm.
Further, described drain valve is installed on the end of described waste pipe.
Further, described drain valve is manual ball valve.
Further, described manual ball valve also opens wide layout by being threaded connection at the end of described waste pipe.
The mist eliminator flushing water lines leakage detection system that the utility model provides, after the valve of existing sparge water arm, (downstream position) increases a drain valve, when finding that flushing pipe has an interior leakage, under the state of sparge water arm valve closing, opening water discharge valve can determine interior leakage valve, and can determine interior leakage quantity.
The beneficial effects of the utility model:
The utility model, can accurate positioning leakage valve after sparge water arm installs leakage detection apparatus additional, greatly saves the leak detection repair cycle, increases work efficiency, thus can control the leakage current of mist eliminator flushing water by bottom line.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of mist eliminator flushing system in prior art;
Fig. 2 is the schematic diagram of a kind of mist eliminator flushing water lines of the utility model leakage detection system; Wherein:
1-rinse jellyfish pipe; 2-sparge water arm; 3-sparge water valve; 4-waste pipe; 5-drain valve.
Embodiment
A kind of mist eliminator flushing water lines of the utility model leakage detection system, as shown in Figure 2, comprise: flushing pipe and leakage detection apparatus, this flushing pipe comprises flushing jellyfish pipe 1 and sparge water arm 2, rinse jellyfish pipe 1 and branch out some sparge water arms 2, sparge water arm 2 is provided with sparge water valve 3; This leakage detection apparatus be connected to be positioned at sparge water valve 3 downstream sparge water arm 2 on, this leakage detection apparatus comprises waste pipe 4 and drain valve 5.
In the utility model, the waste pipe 4 newly installed additional can adopt the material consistent with sparge water arm 2 to be stainless steel, therebetween by being welded to connect.
In the utility model, drain valve 5 can be manual ball valve, is preferably open type, so that check flowing water situation when opening.
When practical application, for Henan 2 × 660MW unit Limestone-gypsum Wet Flue Gas Desulfurization Process demister layer flushing line, rinse jellyfish pipe and connect seven arms, each root arm is an elimination day with fog sparge water arm, and each root sparge water arm is controlled by an electric/pneumatic valve.
Inventor, according to the utility model, transforms above-mentioned rinse-system, and wherein, the stainless steel that the waste pipe material selection in leakage detection apparatus is identical with sparge water arm, is connected to by welding manner on the pipeline after the electric/pneumatic valve of sparge water arm.Waste pipe adopts 4 to be in charge of (wall thickness is 0.6mm, and inner diameter is 11.5mm).Drainage pipe end is threaded connection a manual ball valve and opens wide and arranges, is convenient to observe flowing water situation.
When finding that flushing pipe has interior leakages, under the state of sparge water arm valve closing, opening water discharge valve can determine interior leakage valve, with three layers of spraying layer, carries out the leakage detection work amounting to 21 valves, accurately can find, rate of accuracy reached 100% in 10min.
And do not install the leakage detection work of 21 valves of the rinse-system of leakage detection apparatus additional, estimate needs 2 hours, and accuracy is low can not ensure.
