Step 3, serious for the incrustation in step 2 section is carried out segmentation again, find out the serious point of incrustation;
Step 4, seriously to put at incrustation and be in line perforate, at tapping, perforated valve is installed, gas piping on-line cleaning device is arranged on perforated valve, and is tightly connected with perforated valve;
Step 5, turn on the gas-fire perforated valve on pipeline and high-pressure water, flexible, rotate the incrustation of high pressure water jet pipe to gas piping and rinse, until has rinsed, and closedown high-pressure water and perforated valve.
This method carries out mark segmentation according to Gas Flow to by gas piping according to the affiliated facility on gas piping, each section of pressure is being checked, (pressure differential is large to judge the serious section of pipeline incrustation by the pressure differential between section and section, there is severe deposits in two measurement points), segmentation inspection is being carried out to the incrustation section determined, until find the serious point of incrustation.In the online perforate of incrustation point, at the giant (high pressure water jet pipe) of the outer connecting band omnidirectional mechanism (Universal rotary head) of perforated valve, incrustation point is rinsed, stretch according to the situation of pipe diameter, incrustation point, wave giant (high pressure water jet pipe), flushing water and the impurity rinsed out are got rid of from gas pipeline drainer, after flushing completes, close perforated valve.The present invention can when not stopping transport, and removes gas piping local severe deposits point, safety, economical, reliable.
This gas piping on-line cleaning apparatus structure is simple, easy to make; The cleaning of online gas piping can be realized, safe, economical, reliable; Can reuse, energy-conserving and environment-protective.
This gas piping on-line cleaning method can realize the gas piping cleaning in situation of not stopping the supple of gas or steam, safe, economical, reliable; Technique is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of gas piping on-line cleaning device of the present invention.
In figure: 1, flange closure plate, 2, rotor, 3, sealing ring, 4, high pressure water jet pipe, 5, fixed body, 6, high-pressure water.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.
See Fig. 1, a kind of gas piping on-line cleaning device, it comprises high pressure water jet pipe 4(giant), flange closure plate 1, the omnidirectional mechanism be placed in flange closure plate 1, sealing ring 3, high-pressure water 5;
Described omnidirectional mechanism comprises a rotor 2 and a fixed body 5, and described fixed body 5 is fixedly connected with flange closure plate 1, and described rotor 2 is placed in fixed body 5;
Described high pressure water jet pipe 4(giant) one end insert after rotor 2 and stretch in gas piping, described high pressure water jet pipe 4(giant) the other end be connected with high-pressure water 6;
Described sealing ring has 2 for double-layer seal rings, is placed in omnidirectional mechanism 2 and high pressure water jet pipe 4(giant) between, seal;
Described flange closure plate 1 is connected with gas piping by perforated valve.
In order to realize the flushing of different gas piping caliber and different incrustation point, can by high pressure water jet pipe 4(giant) be designed to be flexibly connected with omnidirectional mechanism 2, i.e. high pressure water jet pipe 4(giant) can wave in omnidirectional mechanism 2, high pressure water jet pipe 4(giant) can move axially, realize extending in gas piping and shortening.
The present invention also provides a kind of and adopts above-mentioned gas piping on-line cleaning device to carry out the method for gas piping on-line cleaning, specifically comprises the steps:
Step one, according to Gas Flow to gas piping being carried out segmentation and marking;
Step 2, pressure inspection is carried out to each section of gas piping, find out the serious section of gas piping incrustation by the pressure differential of section and section;
Step 3, serious for the incrustation in step 2 section is carried out segmentation again, find out the serious point of incrustation;
Step 4, seriously to put at incrustation and be in line perforate, at tapping, perforated valve is installed, gas piping on-line cleaning device is arranged on perforated valve, and is tightly connected with perforated valve;
Step 5, open perforated valve, gas piping on-line cleaning device high-pressure water 5, the incrustation of gas piping is rinsed, until rinsed, close perforated valve and high-pressure water 5.
In step 5, high pressure water jet pipe 4(giant) can carry out flexible according to gas piping diameter, incrustation point size and wave.
This method carries out mark segmentation according to Gas Flow to by gas piping according to the affiliated facility on gas piping, again the pressure of each section is checked, (pressure differential is large to judge the serious section of incrustation by pressure differential between section and section, there is severe deposits in two measurement points), again segmentation inspection is carried out to the serious section of incrustation, until find the serious point of incrustation, line perforate is at incrustation point, perforated valve is installed at tapping, by flange closure plate 1 and perforated valve Flange joint, insert giant (high pressure water jet pipe), open water source to rinse incrustation point, according to pipe diameter, the situation of incrustation point is stretched, wave giant (high pressure water jet pipe), flushing water and the impurity rinsed out are got rid of from gas pipeline drainer, after flushing completes, close perforated valve.This method can when not stopping gas supply (in online situation), removes gas piping local severe deposits point, safety, economical, reliable.
The present invention outputs the manhole of 100mm online, recycles the cleaning that the present invention realizes inside of gas pipeline severe deposits point, eliminate local incrustation after passing through to judge gas piping blocking point near blocking point, simple, practical, safety again.
