A kind of separator of separate solid particles
Technical field
The utility model relates to the solid particle separation field, and particularly, the utility model relates to a kind of solid particle separator.
Background technology
Modern chemistry industry, PETROLEUM PROCESSING are industrial, the energy, pharmaceuticals industry and field of environment protection etc. are widely used solid catalyst.Although solid catalyst is after use, certain variation occurs in its form and catalytic activity, and remaining solid catalyst particle is constant in catalytic activity basically.Therefore, not only cost is low but also high efficiency to reclaim the solid catalyst particle that meets the demands from dead catalyst.
Traditional separation method is all generally to use screening.But for the solid of particle size less than 100 microns, in screening process, the phase mutual friction meeting of solid particle causes large solid particle wearing and tearing, for the user who needs large-size particle as the finished product after separating, economy is very poor, and has all the time the small size solid particle to produce in finished product.
Modern crafts adopt fluid bed to separate more, and the fluid bed separating technology can reduce the impact force between solid particle effectively, makes to drop to minimum because the wearing and tearing between particle cause the possibility that particle size diminishes.CN1188532A disclose a kind of from fluidized bed airflow the separation equipment of separate solid particles.But this separation equipment can be because the shape of the stability fluctuation that air flow rate is controlled and variable grain be different and cause the part large-size particle is taken away to this buoyancy in air-flow of particle.The separating effect of this separation equipment is not remarkable.
CN 102500175A discloses a kind of method that fluidized-bed reactor separates finely ground particles, the related fluidized-bed reactor of the method is its expanding reach of reaction, this expanding reach is comprised of filter, valve, access hole, solid powder import, object position detection device, pressometer, temperature meter and tube connector, at the built-in high-temperature resistant filter of reactor, and switch the mode of blowback in conjunction with many groups, form a kind of built-in filtration dust prevention system.Add reverse nitrogen blowing system at the in-core of filter and carry out blowback, in order to the secondary aggregate of trapped small-sized particle, fall into reactor through blowback and again participates in reacting; So circulation can increase certain economic benefit, and circulation in particle, also stoped leaking outside of dust simultaneously, also will greatly dwindle external environment influence, to reach automation mechanized operation and the purpose that reduces manpower.But the filter of this reactor adopts nitrogen blowback mode to make secondary aggregate fall into reactor and again participates in reaction, and cost is higher and secondary aggregate removing effect is not ideal enough.
CN 102101108A discloses a kind of ultrasonic vibration screen, comprise support, be located at screen cloth on support and the ultrasonic wave head that shakes, the ultrasonic wave head that shakes is located at the outside of support, this ultrasonic wave head that shakes has the biography axle that shakes, support is provided with axis hole, the described biography axle that shakes inserts axis hole and makes the end that passes the axle that shakes pass axis hole from the support outside, this biography shake end of axle is connected with vibration ring, and vibration ring is pressed close to the surface of screen cloth.But it is in screening process, and the phase mutual friction meeting of solid particle causes large solid particle wearing and tearing, and the filter cake removal device is not set, and easily causes filter cake to stop up the situation of filter screen.
US Patent No. 4670993 discloses a kind of for the kaolinic method of fluidisation, a kind of fluidized bed plant is wherein disclosed, it can have separator and vibrating device, but wherein said vibrating device is to be connected on the shell of whole device, its role is to whole material is vibrated operation inconvenience.
