Description

A kind of horizontal coal fines fiber separator

Technical field

The utility model relates to horizontal coal fines fiber separators a kind of in coal gas chemical field.

Background technique

In coal gasifying process, raw coal wears into fine powder through coal pulverizer, is then sent into gasification furnace by burner and gasifies；By In raw coal exploitation, transport, storage etc. on the way, fiber different in size is mixed into coal dust made of need to grinding, there is polybag, porcelain The sundries topsy-turvy such as piece, flax silk will cause and block pneumatic conveying, pipeline and gasification furnace and be bonded in burning in high-temperature gasification At mouth, system production run steady in a long-term is influenced；Celloco fractionator Celloco effect is all fibres in automatic cleaning coal dust: polybag, The sundries such as tile, flax silk, are typically mounted at coal collector rear end, and the outlet of Celloco fractionator Celloco is connect with raw coal warehouse；E mesh Before, the comb filter structure of coal fines fiber separator is generally used the double-layer separating structure of comb thorn combing and grid screen；Grid is Combined type circle sieve plate is made of 3~5 equal piecemeals；Comb thorn item is strip component, towards upper surface length direction every Acicular comb thorn is arranged every 3. 5 ~ 4. 5mm, comb thorn 2~3mm of diameter, combing and piercing long 50~75mmo comb thorn item is in put Shape arrangement is penetrated, the comb on comb thorn item is perverse towards oblique 10~15 ° of arrangements in direction of rotation；Comb filter structure rotation when, have 10~ The comb thorn of 15 ° of angles of lead first combs coal dust, and the long fibre combed out slides to comb thorn root along angle of lead, and grid sifts out comb The perverse staple fiber not cleared out and velvet-like fiber；Once combing the accumulation of fibers of filter structure comb worry to set amount, from clean-up port after shutdown It removes；The Celloco fractionator Celloco of the prior art has the following problems: equipment is vertical structure, and coal dust flows from above to below, beautiful comb filter Mechanism is to rotate horizontally, and comb thorn item is arranged radially, it is difficult to be come into full contact with coal dust, purification efficiency is lower；Actually transporting shape In, since fiber is only wound around in comb thorn, there is no separating treatment, comb thorn smooth surface is carried out, the long fibre combed out exists After sliding to comb thorn root, due to the impact of coal dust and the multiple action of rotational structure, it is easy to be separated with comb thorn, be mixed into coal again In powder, for fiber always present on coal dust channel, pockets of fiber causes grid to block face sound coal dust flux frequent occurrence, blocks up Plug situation is easy to spread to whole cross section, piles with coal dust above grid, kills driving device, equipment is caused integrally to shut down, lattice Grid are paved with whole cross section, only can not be by the coal dust of all accumulations by two maintenance doors in the case where blocking, which occurs, to be rotated It removes, significantly increases the labor intensity of maintenance worker, while influencing system normal operation；One is also disclosed in the prior art A kind of coal fines fiber separator of kind, application number 201410124692.0,103894344 A of application publication number CN, Shen Qing Publication Day 2014.07.02, including shell and comb filter structure, its main feature is that coal pipe and fibre pipe that shell is connected by the cylinder of accumbency Composition, coal pipe and fibre pipe are connect by the beveled cone of bifurcation structure with cylinder, the discharge port and coal pipe and fibre of housing bottom Tie up pipe connection；Coal pipe and fibre pipe top are equipped with the strainer of drawer-type structure；Filter structure is combed by driving device and comb licker-in group At comb licker-in is mounted in cylinder by two axle bed sets being arranged on cylinder；Driving device by bracket be fixed at outside cylinder with Comb licker-in connection；Celloco fractionator Celloco separative efficiency is low, and has damaged during the separation process, is unfavorable for long-term use.
