Description
Technical field
The utility model relates to field of chemical equipment, the feed arrangement of the filter of especially a kind of slag wax and stable wax.
Background technology
F-T synthesis is by the key reaction of ICL for Indirect Coal Liquefaction in coal liquifaction technique, and the wax that F-T synthesis generates, through hydrofinishing and hydrocracking, can manufacture the petrol and diesel oil of high grade; Also directly high melting-point wax can be produced through degassed, cooling.The wax that Chinese patent 201120472284.6---mono-kind is used for Fischer-Tropsch synthesis and slag wax, stablize in Lasaxing Oilfield system, need to utilize filter that the liquid phase slag wax or wax that contain irony catalyst fines are carried out Separation of Solid and Liquid, collect solid phase irony catalyst separation to recycle, highly purified liquid wax then manufactures petrol and diesel oil for deep processing.From the slag wax that Fischer-Tropsch synthesis device is discharged, containing a large amount of powdery fischer-tropsch synthetic catalysts, its solid content is about 8 ~ 20%, and solid content final after separating and filtering needs to be less than or equal to 5ppm, and filtering requirement is very high.
Slag wax refers to containing a large amount of particle diameter the liquid wax of the solid impurity such as catalyst being 20 ~ 200um, and fusing point is 90 DEG C ~ 100 DEG C, and 180 DEG C time, density is about 689 ~ 800kg/ m
3; In slag wax, the density of solid impurity is about 4 ~ 6 times of liquid wax density, and solid-liquid density difference is very large.Even if liquid wax is in molten state, viscosity is still very large, and mobility is very poor, therefore can not directly adopt existing separator-filter to carry out Separation of Solid and Liquid to slag wax.
Utility model content
The applicant can not carry out the shortcoming of Separation of Solid and Liquid for above-mentioned existing separator-filter to slag wax, provide a kind of feed arrangement of rational slag wax filter, thus can effectively realize being uniformly distributed of slag wax mixed liquor.
The technical scheme that the utility model adopts is as follows:
A kind of feed arrangement of slag wax filter, described slag wax filter is to be positioned at the central collection tube of vertical cylinder enclosure interior central authorities for axis, parallel some horizontal blades are installed, housing bottom is provided with lower feed pipe, described case top is provided with upper feeding pipe, be positioned at below upper feeding pipe in enclosure interior and be provided with baffle plate, or the upper feeding distributor pipe of annular is set.
Further improvement as technique scheme:
Vertically be provided with at least one side feed pipe in enclosure interior, the tube wall of side feed pipe is provided with some sides charging hole, charging hole perforate direction, side is the tangential direction along housing cylindrical.
The beneficial effects of the utility model are as follows:
The utility model improves based on existing level tray formula leaf filter, by increasing blade thus increasing its work disposal amount, by improving feed system, top charging is set and side direction charging makes the mixed liquor in device interior cavity be evenly distributed, thus ensure that the live load of blade is even, adapt to the different large feature of slag wax solid-liquid density difference.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1 and Figure 2, slag wax filter described in the utility model improves based on existing level tray formula leaf filter, to be positioned at the central collection tube 5 of vertical cylinder housing 6 center of inside for axis, parallelly be provided with some horizontal blades 1, every sheet horizontal blade 1 is made up of blade body, filtration channel layer, seal, space collar etc.Lower feed pipe 2 is provided with bottom vertical cylinder housing 6, it is inner that liquid-solid mixed liquor enters housing 6 by lower feed pipe 2, and upwards overflowing internal cavity, the liquid in mixed liquor enters central collection tube 5 by the filtration channel laminar flow on blade 1 surface, and discharges through discharge nozzle 3; Solid in mixed liquor is trapped within filtration channel layer surface and piles up gradually, when after work certain hour, the solid of overheap can affect filter efficiency, now the mixed liquor of housing 6 inside is discharged, and by air-blast device by nitrogen from top to the inner air blast of housing 6, the solid residual to blade 1 upper surface dries up, simultaneously also Ethylene recov phase constituent as much as possible.Then the motor 7 of filter top is started, drive central collection tube 5 and all blade 1 High Rotation Speeds, utilize centrifugal force to be shed by blade 1 surface solid and carry out de-slag to housing 6 inwall, residue falls to bottom cone bucket, is discharged by solid finally by bottom slag discharge.
Liquid phase in mixed liquor handled by the existing level tray formula leaf filter normally good water of mobility or solution, solid phase is generally active carbon or sand grains etc., the density contrast of this solid liquid phase is not very large, thus solid phase can than being easier to be evenly distributed in liquid phase, and thus existing level tray formula leaf filter only arranges lower feed pipe 2 in bottom.And slag wax solid-liquid density difference handled by the utility model is very large, after slag wax enters housing 6 inner chamber from bottom, the solid phase that density is larger can be deposited on bottom under gravity rapidly, very fast just accumulation the in the horizontal blade 1 of bottom surface is caused to have blocked up solid-phase layer, and horizontal blade 1 surface on top does not retain solid phase substantially, the solid particle that upper and lower horizontal blade 1 is tackled is extremely uneven.This unbalanced live load not only needs to carry out de-slag and cleaning to blade 1 continually, and the serious curtailment working life of whole equipment.For the feature of material handled by the utility model, as shown in Figure 1, the utility model is provided with upper feeding pipe 21 at housing 6 top, be positioned at below upper feeding pipe 21 in housing 6 inside and be provided with baffle plate 22, carry out charging to housing 6 inner chamber by upper feeding pipe 21 and lower feed pipe 2 during work simultaneously, and reduce flow velocity by baffle plate 22, realize the average temperature distribution of mixed liquor.By above-mentioned improvement, the solid particle that upper and lower blade 1 surface retains is substantially equal, and effectively average live load, improves filter efficiency, extend equipment life.The upper feeding distributor pipe of annular can certainly be set, realize uniform cloth.
Existing horizontal blade separator-filter treating capacity is less, usually only arranges the horizontal blade 1 of about 30; And project treatment amount of the present utility model is large, horizontal blade 1 needs to be set to more than 60, and treating capacity is more than the twice of existing filter.In order to the live load of further mean leaf 1, the utility model is provided with side charging aperture 23 at housing 6 side opening, housing 6 inner vertical is provided with at least one side feed pipe 24, as shown in Figure 3, some sides charging hole 25 is evenly equipped with at the tube wall of side feed pipe 24, side charging hole 25 is not directly just offered direction blade, and its perforate direction is the tangential direction along housing cylindrical.During charging, mixed liquor circumferentially tangentially enters housing 6 inner chamber, avoids producing directly impact to the slag blanket that blade 1 is trapped and affecting filter effect.By arranging side feed pipe 24, mixed liquor being uniformly distributed on whole height can be ensured, the live load relative equilibrium of the upper and lower blade 1 of equipment of high throughput can be realized.
During real work, because the material mouth of charging aperture is larger up and down, charging is fast, so utilize it as initial quick feeding; Then utilize the charging as a supplement of side feed pipe at filtration duration of work, side feed tube is relatively milder, thus can ensure that the mixed liquor of inside cavity is evenly distributed up and down.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, when without prejudice to the utility model spirit, the utility model can do any type of amendment.
