Technical field
The utility model belongs to petrochemical technology field, is specifically related to a kind ofly for polyolefin medium transport (wind send or gravitational discharge) process, eliminate the safety device of static, specifically a kind of polyolefin bunker Xelminator for Pipeline transport.
Background technology
In petrochemical enterprise polyolefin media processes place, medium due to friction, broken, the reason such as peel off, can carry a large amount of static, the harm of polyolefin dielectric charge is larger, not only can cause feed bin dust wall built-up, it is quick-fried that static discharge even can cause that package mouth dodges, and in feed bin, local sudden strain of a muscle quick-friedly still fires to whole feed bin.Existing static technology for eliminating and product, mainly by spray point and malleation air chamber (high pressure chest) two parts, formed, its spray point is vertically mounted on conveying pipeline outer wall by needle stand, owing to there being the plastic grain of high-speed cruising in pipeline, larger to the insulated part of needle stand (being generally highly dense plastics) destructiveness, spray points seat (insulated part) is short useful life, is easy to cause reduce the electrical efficiency that disappears because of insulation breakdown.Moreover existing equipment high pressure generator is directly installed in high pressure chest, in the ventilation hole by spray points seat and pipeline, medium, in same gaseous environment, if high pressure generator is because of fault generation detonation own, may cause that pipeline fires, and is absolutely unsafe.In addition, have airduct to be connected with wind regime outside chamber in high pressure chest, airduct carries out pipeline with each spray points by wind joint and is connected, and the one, chamber gut line is mixed and disorderly, the 2nd, fitting operation inconvenience, the 2nd, air quantity is unstable, thereby affects its working effect.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide the polyolefin bunker Xelminator of a kind of efficient, safety and long service life.
Polyolefin bunker Xelminator of the present utility model, by sealing baffle, be provided with healthy tendency pressure chamber destaticing on part conveying pipeline tube wall, in indoor the destaticing of positive air pressure, cation and anion spray points are housed on part conveying pipeline tube wall, spray points leads in conveying pipeline, described spray points afterbody connects high-tension cable by resistance, and spray points and resistance are fixed in spray points seat by sealing resin; Spray points seat is installed on and is destaticed on part conveying pipeline tube wall by needle stand fixed mount, it is characterized in that spray points seat is provided with two symmetrical ventilation holes, ventilation hole is communicated with healthy tendency pressure chamber, healthy tendency pressure chamber is provided with wind joint and is connected with extraneous air wind regime, and the wind joint of healthy tendency pressure chamber connects external pressure sensor; Healthy tendency pressure chamber is provided with outlet and is connected with negative high-voltage generator with the positive high voltage generator in explosion-proof tank by cable sealed joint, and explosion-proof tank connects outside regulator by cable sealed joint; All positive ions spray points high-tension cable and positive high voltage generator high-voltage line pool together to insert in plastic tube and are sealed by sealing resin, and all anion spray points high-tension cables and negative high-voltage generator high-voltage line pool together to insert in plastic tube and sealed by sealing resin.
As further improvement of the utility model, two ventilation holes on spray points seat become the angle of 75～130 degree.
As further improvement of the utility model, the diameter of described ventilation hole is 0.8～1.0mm.
As further improvement of the utility model, described spray points with destatic part conveying pipeline tube wall plane and be 5 °～12 ° and tilt install.
The beneficial effects of the utility model are as follows:
1, positive or negative high voltage generator is arranged in the external explosion-proof tank of Xelminator, guarantees that equipment is used safety, maintains easily simultaneously and changes;
2, spray points tilts to be installed on conveying pipeline tube wall, effectively reduce the wear rate of spray points seat, increase the contact area of ion and charged polyolefin particles simultaneously, increase the electrical efficiency that disappears, but angle of inclination unsuitable excessive (over 12 °), otherwise can extend the electrical distance that disappears, the electric data that disappear really cannot be detected, even cannot operate;
3, change ventilation hole diameter and position (being close to spray points and insulating needle seat contact site), both can lower air quantity consumption, also can blow out all ionized airs, guarantee the electrical efficiency that disappears;
4, cancelled airduct, healthy tendency pressure chamber directly connects external wind source, not only easy to operate, has lacked wind joint, equipment is installed simpler, the more important thing is that ventilation quantity is even, has guaranteed the working effect of equipment.
