Abstract
The invention relates to a conical gas distributor. The conical gas distributor comprises a plurality of sieve meshes, wherein a wear-resistant bump is arranged in each sieve mesh; the central part of the wear-resistant bump is provided with a solid particle passing hole; each wear-resistant bump comprises a wear-resistant bump body, an upper fixture and a lower fixture; the length of the wear-resistant bump body is more than the thickness of the wall of the gas distributor; and after the wear-resistant bump body is inserted into the sieve mesh, the upper fixture and the lower fixture are fixedly connected with the wall of the gas distributor by the upper end and the lower end of the wear-resistant bump body through a horizontal fixing device and a vertical fixing device respectively. Because the wear-resistant bump is fixed on the wall of the gas distributor through the horizontal fixing device and the vertical fixing device, the wear-resistant bump can bear the collision of silicon powder which moves at a high speed without separating or loosening components at high temperature and under high pressure by mutually matching the two fixing devices, so that the service life of the gas distributor is prolonged.
Description
Technical field
The present invention relates to a kind of gas distributor that is adapted to chemical field, especially relate to gas distributor in a kind of fluid bed.
Background technology
The a large amount of using gases distributors of chemical field have flat, the spherical crown shape and taper.It one of mainly acts on is for allowing reactant evenly distribute, accelerating reaction efficiency and shorten reaction time.
For example, the fluid bed in the organosilicon manufacturing field just needs to use the conical gas distributor.As depicted in figs. 1 and 2, on gas distributor 11, be provided with a plurality of sieve apertures 12.After silica flour enters HTHP fluidisation bed, need enter finger-type heat exchanger tube place by a plurality of sieve apertures 12 on the gas distributor 11 and carry out chemical reaction.
But pulverous silica flour has carried a large amount of impact energys under the condition of HTHP.During sieve aperture 12 on entering gas distributor 11, can bump and rub with sieve aperture periphery place 13, and sieve aperture periphery place 13 also just becomes the place that is worn easily.After time is permanent, will be worn out the hole of depression, sieve aperture periphery place 13, make the operating efficiency of gas distributor reduce and solid particulate distributions inhomogeneous.
Therefore, the above-mentioned defective gas distributor that will badly influence and the driving time and the time between overhauls(TBO) of fluid bed.For example, gas distributor seriously will be replaced within half a year owing to being worn, and fluid bed and whole organosilicon manufacturing equipment all need the maintenance of stopping during replacing, thereby can badly influence operating efficiency, has also caused the unnecessary wasting of resources simultaneously.

As shown in Figure 6, the length of wear-resistant raised bodies part 22 is greater than the thickness summation of upper fixing element 23, following fixture 24 and gas distributor wall 21, and the zone that wear-resistant raised bodies part 22 two ends exceed upper fixing element 23 and following fixture 24 respectively is a boss 27.Thereby can further increase the silica flour of input and output gas distributor and zone and the time that wear-resistant projection wearing and tearing contact, thereby further prolonged the service life of gas distributor.
The distributed number mode of a plurality of sieve apertures 12 on gas distributor is interior structure of dredging outside close.This constructor closes the distribution mode and a distribution mode of interior heat of the finger-type heat exchanger tube of fluid bed, the finger-type heat exchanger tube of gas distributor zone line top is more and heat concentrated, fully react in order to make more silica flour enter this zone, thereby offer more sieve aperture at the gas distributor zone line, and in the neighboring area because finger-type heat exchanger tube negligible amounts and heat are low relatively, thereby the sieve aperture limited amount of offering in the gas distributor neighboring area, to guarantee best reactiveness.
As shown in Figure 7,26 one-tenth one concentric structures in the current hole of wear-resistant protruding 2 wear-resistant raised bodies part 22, upper fixing element 23 and solid particle.Connect three standing screws 25 on each wear-resistant raised bodies part 22, the angle of the formation between any two standing screws 25 is 120 degree.Thereby three tie points form equilateral triangles, make being fixed on the gas distributor wall 21 that each wear-resistant raised bodies part 22 can be stable.
As shown in Figure 8, the upper/lower terminal of wear-resistant raised bodies part 22 all is provided with vertical screw thread 28.
As shown in Figure 9, the present invention is wear-resistant protruding 2 also to exist the 4th kind of structure, and a kind of conical gas distributor comprises a plurality of sieve apertures, is respectively equipped with a wear-resistant projection in described a plurality of sieve apertures, is provided with the current hole of a solid particle in the center of wear-resistant projection; Wear-resistant projection comprises a wear-resistant raised bodies part, upper fixing element and following fixture, and the length of wear-resistant raised bodies part is greater than the thickness of gas distributor wall; Following fixture and wear-resistant projection are integral piece, and form the wear-resistant raised bodies part of a T type, after the T type is wear-resistant raised bodies part inserted in the sieve aperture, the T type is wear-resistant, and the raised bodies part was fixedly connected on upper fixing element on the gas distributor wall by a horizontal fixed device and vertical fixing device.
This horizontal fixed device is a standing screw 35, is provided with the thread groove that is complementary with standing screw 35 on upper fixing element 33 and the wear-resistant raised bodies part 32 of T type.The upper end that this vertical fixing device is wear-resistant raised bodies part 32 is provided with vertical screw thread 37, also is provided with the vertical screw thread 37 that is complementary on the upper fixing element 33;
Connect three described standing screws 35 on the wear-resistant raised bodies part 32 of each T type, the angle of the formation between any two described standing screws 35 is 120 degree.Thereby three tie points form equilateral triangles, make being fixed on the gas distributor wall 31 that the wear-resistant raised bodies part 32 of each T type can be stable.
The distributed number mode of described a plurality of sieve aperture 12 on gas distributor is interior structure of dredging outside close.This constructor closes the distribution mode and a distribution mode of interior heat of the finger-type heat exchanger tube of fluid bed, the finger-type heat exchanger tube of gas distributor zone line top is more and heat concentrated, fully react in order to make more silica flour enter this zone, thereby offer more sieve aperture at the gas distributor zone line, and in the neighboring area because finger-type heat exchanger tube negligible amounts and heat are low relatively, thereby the sieve aperture limited amount of offering in the gas distributor neighboring area, to guarantee best reactiveness.
The diameter of the T type is wear-resistant raised bodies part 32 equals the diameter of described sieve aperture 12.This structure also makes the wear-resistant raised bodies part 32 of T type have better matching with gas distributor wall 31.
