Description
Technical field
The present invention relates to chemical technology field, especially a kind of automatic desludging pipeline and method.
Background technology
Often production efficiency is influenceed in phosphoric acid or oil-gas pipeline conveying because of fouling.Make pipeline undergauge after pipeline scale, flow
Logical sectional area diminishes, and build-up of pressure damage, discharge capacity reduces and line clogging, and it is local rotten that line clogging fouling can also induce pipeline
Erosion, cause pipe leak frequently or even perforate, damage sexual behavior event, therefore commonly use chemical cleaning, high pressure in the industrial production
Water sprays scale removal, mechanical descaling, ultrasound wave descaling etc. but these scale removal mode effects are all undesirable.Patent before inventor
" remove fouling composite material conduit and scale removal structure and descaling method (number of patent application：CN201510876633.3), except fouling is answered
Condensation material pipeline and scale removal structure (number of patent application：CN201520990442.5), the scale removal knot of good antiscale property composite material conduit
Structure and its application method (number of patent application：CN201510473147.7 using soft or hard combination pipeline and by by external in) "
Equipment (external pressure or vavuum pump) makes liner hose deformation that dirt destruction is played into scale removal effect, positive effect, has been applied.
But it is somewhat cumbersome to need external equipment to deform flexible pipe in patented technology.
The content of the invention
It is an object of the present invention to provide a kind of automatic desludging pipeline and method, it be not required to by external equipment can scale removal,
And it is simple and easy, cost is cheap.
What the present invention was realized in：Automatic desludging pipeline, including hard tube, more than two flexible pipes are provided with hard tube,
Flexible pipe, in the helical form mutually wound, is respectively equipped with corresponding with flexible pipe quantity and right in hard tube in the front end of hard tube and end
The flexible pipe import and flexible pipe outlet, flexible pipe for claiming distribution are fixedly connected with corresponding flexible pipe import, in flexible pipe and the company of flexible pipe import
Connect opening position and be provided with valve.
The external diameter of single flexible pipe is the 70-90% of hard tube internal diameter, and the total length of single flexible pipe is the 1.5-2 of the length of hard tube
Times.
Described flexible pipe is rubber tube, flexible PVC pipe or liner IR fiber pipe.
Flange is equipped with every flexible pipe both ends.
Automatic desludging method, when in use, a wherein flexible pipe is first opened, the valve of remaining flexible pipe is closed, makes work defeated
The liquid sent is conveyed in the flexible pipe, and after fouling occurs in the flexible pipe, the valve of the flexible pipe is closed, opens other one
The valve of flexible pipe, now liquid flowed through from this root flexible pipe newly opened, the flexible pipe that the flexible pipe of fouling is newly opened squeezes
Pressure, so as to which the flexible pipe of fouling be shriveled, it is crushed the dirt in the flexible pipe of fouling；There is the situation of fouling in the flexible pipe for treating newly to open
Afterwards, the flexible pipe is turned off, opens any one flexible pipe without fouling to convey liquid, if having carried out scale removal before the flexible pipe,
The dirt being then crushed is rushed out therewith, that is, is completed scale removal, constantly switched conveying liquid just between each flexible pipe in hard tube
Scale removal can be played a part of.
Compared with prior art, the present invention uses sets more than two mutual spirally-wound flexible pipes in hard tube,
Flexible pipe is respectively enterd and stretch out hard tube with different joints, and realized by different valves and control opening for each flexible pipe respectively
Open or close, in use, only make wherein flexible pipe conveying liquid, the flexible pipe of this root conveying liquid work one section when
Between, after there is fouling in flexible pipe, then another flexible pipe conveying liquid is switched to, in so avoiding make pipeline after pipeline scale
Undergauge, actual internal area diminish, and build-up of pressure damage, discharge capacity reduce and the problems such as line clogging, and change another it is soft
During pipe conveys, also the flexible pipe for previous root knot dirt has carried out scale removal, and Reusability is the effect that can reach automatic desludging,
And without external any equipment, simple to operate, cost is cheap, and using effect is good.
