Description
Technical field
The present invention relates to liquid material pipeline conversion facility, more particularly to a kind of liquid material pipeline conversion fixation means and
Using the purging and pigging method of the fixation means.
Background technology
Oil product（Containing edible oil）, the liquid material huge number such as fluid chemical product, even if material component of the same race there is also one
Difference is determined, frequently with pipeline in liquid material storage and transport process.The public storage project of liquid material, lease client is reluctant oneself
Liquid material and other people multi-product pipelines influence quality, therefore tank field in usually using special storage tank and dedicated pipe, it is large number of.
And the place such as harbour is limited by place, it is impossible to which special using managing, this just needs to shorten the length of public pipe as far as possible, in tank field
Correct position（Such as access bridge root）Pipeline switching station is set, dedicated pipe conveying material is changed to public pipe, finished per subjob
Public pipe is cleaned up afterwards.
To meet the conversion of public pipe and dedicated pipe, need to be flexibly connected using flexible pipe at present, working strength is big, operational efficiency
It is low.Flexible pipe artificial unloading has material evaporating, emitting, dripping or leaking of liquid or gas, and influence workman is healthy, and generation environment harm easily becomes accident hidden
Suffer from, relevant departments intend abrogating in plain text；Other flexible pipe also needs periodic detection to change, and also increases operating cost.
Therefore safe and reliable, economically feasible need to be set, conveniently managed according to the characteristic of liquid material, field of employment
Change fixation means in road.
The content of the invention
The purpose of the present invention, is to develop a kind of pipeline conversion fixation means, realize public pipe it is more convenient with dedicated pipe,
Change safe efficiently, can not only reduce labour intensity, improve operational efficiency and security reliability, and cause operating cost
Reduce.
Technical scheme is as follows：
A kind of liquid material pipeline changes fixation means, including 4 groups of valve, 2 groups of pipe cleaning emittings and reception device, 3 groups of purgings
Mouth, public pipe branch pipe, header, dedicated pipe branch pipe, pressure gauge and atmospheric valve；Public pipe end sets 1 group of first valve and 1 group the
One pipe cleaning emitting and reception device, pressure gauge and the first blow valve port are set in the first pipe cleaning emitting and reception device；It is special
Pipe end sets 1 group of the 4th valve and 1 group of second pipe cleaning emitting and reception device, on the second pipe cleaning emitting and reception device
Pressure gauge and the second blow valve port are set；Public pipe connects special by public pipe branch pipe connecting manifold pipe, header by dedicated pipe branch pipe
With pipe, 1 group of second valve is set on public pipe branch pipe, 1 group of the 3rd valve is set on dedicated pipe branch pipe, the 3rd valve abuts header
With the threeway of dedicated pipe branch pipe, 1 group of the 3rd blow valve port, the installation of relief valve in the middle part of header are set on header；Public pipe branch pipe from
Public bottom of the tube is picked out, and is connected to the absolute altitude dedicated pipe branch pipe lower than public pipe branch pipe, the gradient of dedicated pipe branch pipe by header
Not less than 5 ‰.
During work, material is purged to ship or corresponding dedicated pipe in public pipe, and purging header is ensuring header and public
Pipe branch pipe noresidue liquid, the valve of pipe special bifurcation avoids the occurrence of cecum against threeway after header.The invention maximum journey
Degree ensure that the cleaning of common-use tunnel, it is to avoid material it is mixed defeated, improve reliability of operation.
Present invention simultaneously provides the purging and pigging method of aforesaid liquid material pipe conversion fixation means.
The step of material is swept to ship in public pipe is as follows：During normal handling operation, the first valve, the 4th valve are in and close
Closed state, the second valve and the 3rd valve are in opening；When pipeline cleaning is changed after the completion of handling operation, the second valve is closed
Door, opens the fast opening blind of the first pipe cleaning emitting and reception device, places wiper；Then gas pipeline access first is blown
Mouth is swept, the first valve is opened；After wiper reaches harbour reception device, open the second valve and continue to be closed after purging some time
First valve, the second valve；Open the 3rd blow valve port and purge, the 3rd valve is closed after purging, the purging of public pipe is completed.
The step of material is swept to corresponding dedicated pipe in public pipe is as follows：During normal handling operation, the first valve, the 4th valve
It is closed, the second valve and the 3rd valve are in opening；When pipeline cleaning is changed after the completion of handling operation, open
First valve, from harbour purging, after wiper reaches the first pipe cleaning emitting with reception device, closes the first valve；Continue
The second valve is closed after the purging some time；Open the 3rd blow valve port and purge, the 3rd valve is closed after purging, public pipe blows
Sweep completion.
Dedicated pipe need not be cleaned every time, when process conditions requirement, accumulating material are changed or overhauled, open second clear
The fast opening blind of pipe device transmitting and receiving device, places wiper, opens the 4th valve and the second blow valve port；When wiper is reached
After the reception device of tank field, the 4th valve and the second blow valve port are closed, the purging of dedicated pipe is completed.
A kind of liquid material pipeline conversion fixation means of the invention, can meet different owners, different qualities material to code
The requirement of first-class Work places, with extraordinary practicality, economy and reliability.And a kind of liquids that the present invention is provided
Pipe material is purged and pigging method, efficiently, economically and safely solves Active workings in huge number liquid material storage and transport process
Limitation.
Liquid material pipeline conversion fixation means of the invention and corresponding liquid material blowing pipeline and pigging method, can
It is widely used in oil product（Containing edible oil）, the first-class place of the public storage item code of the liquid material such as fluid chemical product safety it is defeated
Send, have a extensive future.
