Description
Technical field
The present invention relates to a kind of device and method that electrostatic is eliminated with vibration, belong to strength diluted phase transport technical field.
Background technology
The high-insulativity of polyolefin pellets, cause its pellet transporting, in stacking process, take electrostatic and be not easy to eliminate, enter
And cause " electric discharge of stacking states high-insulativity bulky grain powder turns into the Ignition sources of dust cloud ".China polyolefine powder storehouse exists
Once more than 70 occurred between nineteen eighty-three to 2000 and plays electrostatic explosion accident, 12 electrostatic explosion accidents occur again in last decade.According to
The he result of investigation of accident, the polyolefin bunker dust explosion overwhelming majority are dust, gas, caused by electrostatic collective effect.
Wherein, live wind send electrostatic electrification amount more in 1-5uc/kg, experimental data (0.45-1.8uc/ with external (CIBA) report
Kg it is) basically identical.Live wind plays electricity and material shapes, size, conveying air velocity and load, tube wall deposit during sending material
The factors such as thickness, air humidity influence, therefore live wind send the electrostatic electrification of material to be difficult to predict.Domestic and international accident background and reality
Test room research to show, suppress the electrostatic explosion of the high-insulativity powder material warehouses such as polyolefin, only rest on technical process control and pipe
Reason is inadequate, and the static content reduced or eliminated during material pneumatic conveying is reliability and the optimal side of economy in numerous measures
Case.
Modern times prevent, destatic technology, including humidification removes electricity, add charged preventor, and ground connection goes electricity, ion wind static elimination
Deng technical approach.At this stage, it is ion applied to preventing in polyolefin pellets Geldart-D particle, destaticing relatively common technical approach
Wind static elimination technology, but the technology is there is also its peculiar technological deficiency, ion wind is in and particle surface electrostatic charge mistake
Cheng Zhong, in ion wind and electric charge is excessive, deficiency or uneven, cause ion wind eliminate after pellet still carry electrostatic charge, it is special
In the case of even with more electrostatic charges, that is, electric charge cross supplement, so as to trigger new explosion danger.We are invented
Vibration static elimination method, then be that make use of ground connection to remove electrostatic principle, effectively remove polyolefin take electric charge while, have
Electric charge caused by effect is avoided during ion wind static elimination crosses supplementary question.
The content of the invention
A kind of the present invention is intended to provide polyolefin pellets Geldart-D particle electrostatic simple in construction, easy for installation, highly reliable
Removing method.
In order to achieve the above object, the technical solution adopted by the present invention is：In a kind of Geldart-D particle electrostatic is eliminated with vibration
Device and method, eliminated with vibration in a kind of Geldart-D particle the device of electrostatic by charging aperture, discharging opening, vibrating motor,
Stainless steel contact plate and organization.
The charging aperture to discharging opening is designed with an inclination angle；Multilayer stainless steel contact plate, stainless steel are fixed with body
Contact plate tilts along charging aperture to discharging opening side；Vibrating motor is connected with body, and body and not is driven when vibrating motor works
The steel contact plate that becomes rusty produces vibration；The design at inclination angle and the vibration of vibrating motor ensure polyolefin pellets low speed in Xelminator
Motion；Hierarchical design, the effective surface area inside sieve nest is increased, increase pellet conveying capacity, ensure that polyolefin pellets table
Face is fully contacted with stainless steel contact plate.
Shallow hole is stamped with the stainless steel contact plate, increases the contact area of polyolefin pellets and stainless steel contact plate.
Stainless steel contact plate is designed with feed end and discharge end, during using multilayer contact harden structure, contact plate by the superiors' contact plate extremely
Orlop contact plate, from large to small, discharging end opening is on the contrary, should change from small to big for charging end opening.This design, ensure that polyene
Hydrocarbon pellet can be equably become scattered about on each layer stainless steel contact plate after entering Xelminator, without being deposited in one layer of contact plate
On, cause putty.Diffusing baffle ridge is designed with stainless steel contact plate simultaneously, ensures that pellet uniformly can divide on contact plate
Cloth.
During specific works, the device for eliminating electrostatic in Geldart-D particle with vibration is directly mounted at feed bin top, charging aperture
Feeding pipe is directly connected to, opens vibrating motor, pellet enters body via charging aperture, and pellet contacts with stainless steel contact plate,
Pellet electric eliminating, pellet enter feed bin from discharging opening.
The present invention rolls polyolefin pellets low speed on stainless steel contact plate, makes each surface of pellet be contacted with stainless steel
Plate fully contacts, and its surface charge is fully removed.During whole electrostatic charge eliminates, the new electric charge such as ion wind is not introduced,
Excessive electric charge supplement, deficiency, non-uniform phenomenon will not be produced, electrostatic charge caused by electric charge supplement failure is avoided from principle
Cross supplementary question.It is simple in construction, it is easy for installation, it is highly reliable.
