Background technology
With the quickening of Process of Urbanization Construction process, discarded pipe original is laid with pipe position and is much in during pipe network improving
Under city express lane, building, excavates and take out that there are difficulty is big and costly, pipeline company can only also stay in discarded pipe
Original place.Why discarded pipe is easy to endanger environment, main reason is that medium therein is not removed thoroughly, with
The aggravation of corrosion, poisonous and harmful, inflammable and explosive medium can be discharged into environment, and become security risk.About pipeline, leakage,
The event report of explosion is not an example.So to eliminate this security risk, primary and foremost purpose is carried out to the medium in pipeline
It thoroughly removes.
The discarded long-distance transport pipes cleaning of tradition needs a large amount of water sources using water as power source, and a large amount of oily wastewaters after handling
Processing needs substantial contribution, is the difficult first cause of discarded long-distance transport pipes cleaning.
Invention content
The purpose of the present invention is to provide a kind of transmitting-receiving ball system and pipeline flush scheme for exhaust gas long-distance transport pipes,
Its power source is changed to clean air source by traditional water source, while reducing large-scale ball valve one needed for traditional ball serving device service end
It is a, solve the problems, such as that water resources problem and a large amount of oiliness sewage treatments are of high cost when tradition discards pipeline flush.
The present invention to achieve the above object, is achieved through the following technical solutions：

It includes the ball collecting barrel being sequentially communicated, Concentric Reducers, receive ball guide pipe, described one end for receiving ball guide pipe is equipped with electrical ball valve
And connect with waste line by electrical ball valve, the ball collecting barrel is equipped with fast opening blind, institute far from the one end for receiving ball guide pipe
It states to receive ball guide pipe and be equipped with and leads to ball indicator, the ball collecting barrel is equipped with counterbalance valve, media outlet C, air inlet, blowdown
Mouth, gauge port, emptying elbow.
The bottom end of Z-type bend pipe is equipped with drain N4, the drain N4 and is equipped with blank flange.
The bottom of the service cylinder and the bottom of ball collecting chamber are respectively provided with fixed saddle.
The Z-type bend pipe includes 45 ° of elbows and stage casing straight tube, and 45 ° of elbows are two and are connected to stage casing straight tube
Both ends.
The power entrance N1, medicament entrance N2, shut-off valve is equipped on drain N3, the drain N3 is set to
The bottom of service cylinder, the top of the service cylinder is equipped on drain F1, the drain F1 to be connected with by shut-off valve
180 elbows.
The mirror mouth includes mirror mouth S1, mirror mouth S2, mirror mouth S3, and three mirror mouths are staggered successively
In the both sides of service guide pipe.
A kind of pneumatic train formula exhaust gas long-distance transport pipes cleaning program using above-mentioned transmitting-receiving ball system, and includes following step
Suddenly：
Step 1) opens fast opening blind and is packed into first wiper X1, ultromotivity entrance N1 additions water source will using hydraulic pressure
Wiper drains pressure release after being pushed into the last one observation panel S, and is packed into second wiper X2, medicine is packed into from medicament entrance N2
Agent, powder charge make wiper X simultaneously1To being pushed forward, wiper X1With wiper X2Between medicament install after, close medicament entrance
Water source is added by wiper X from power entrance N1 in N22It pushes at reducing, repeats aforesaid operations and load X3(n is nature to~Xn
Number) filling of discarded pipeline is finished；
Step 2) serves a ball cylinder by power entrance N1 switching air source dynamic pressurizations, and ball collecting chamber is pressurizeed by air inlet, makes liter
After being depressed into 0.6~1.0MPa and balancing, control pressure at two ends keeps the pressure difference of 0.1~0.3MPa, make wiper Xn with 0.1~
The speed of 0.2m/S is advanced, and the counterbalance valve sets pressure as 0.6~1.0Mpa；
Step 3) is received ball one by one to the wiper Xn for marching to ball collecting chamber, and recycles oily wastewater.
In the step 3), when wiper Xn is by logical ball indicator, triggering service cylinder stops supercharging, wiper Xn
After falling into ball collecting barrel, electrical ball valve is closed, oily wastewater is discharged from sewage draining exit and recycles, wherein first section oily wastewater directly fills
Enter tank car recycling, the oily wastewater since second segment passes sequentially through cyclone air-flotation device and more medium filter, and filtering is received
Collect oil slick, it is qualified to treated a small amount of water source detection after qualified discharge.
The prior art is compared, the beneficial effects of the present invention are：
The present invention is mainly by air power source instead of up to ten thousand tons of oily wastewaters in discarded long-distance transport pipes cleaning process
Process problem considerably reduces Cleaning pipes cost.
Ball-loading hole is raised into a caliber in service cylinder one end, is served a ball one by one, is sent using the special service cylinder of the present invention clear
By hydraulic pressure by wiper one by one loading tube, and different agents, additive amount of medicament root is added by pigging process demand in pipe device
Consider according to pipe diameter size to be cleaned, caliber length, greasy dirt thickness etc..Big mouth must be had by solving tradition service cylinder front end
The problem of diameter ball valve, has saved cost, improves efficiency.
During traveling, the cleaning that pulsed promotes is solved the problems, such as.Pulsed principle of propeller is, when leading portion air pressure liter
After up to arriving wiper static friction critical point, wiper will pulsed moves a distance forward at a terrific speed.The arteries and veins
The disadvantage for rushing formula movement is that integral train formula wiper movement speed changes greatly, when it is fast moved, on tube wall
The cleaning of crude oil spot is not thorough, and cleaning performance is not achieved.Therefore, pneumatic type is discarded crude oil pipeline cleaning and cannot be applied.This hair
Bright train type wiper both ends air pressure balance and pneumatic ejector sleeve will clean train using the special service cylinder of the present invention and ball collecting chamber
Both ends injecting compressed air makes the both ends of wiper keep the pressure difference of 0.1~0.3MPa, with the operation speed of 0.1~0.2m/s
Degree pushes wiper to shift to end from head end.Solves the defect of pulsed propulsion.
In addition, the present invention receives ball one by one, wiper is received using the special ball collecting chamber of the present invention, and subsection receiing contains greasy dirt
Water.First section high concentration oily wastewater can be directly loadable into tank car recycling, and the low concentration oily wastewater since second segment is successively
By cyclone air-flotation device and more medium filter, oil slick is collected by filtration, to row up to standard after treated a small amount of sewage detection qualification
It puts.
