Abstract
The utility model relates to a spray drier for preparing poly aluminium chloride, including casing, hot -blast main and atomizer, the casing inside be provided with porous inner tube, porous inner tube is opened has a plurality of through -holes, the clearance between porous inner tube and the casing forms the wind channel, the hot -blast main install at the casing top, the hot -blast main lower extreme is connected with hot air distributors, the hot -blast main passes through branch pipe and wind channel intercommunication, the casing lower part is equipped with the discharge gate, the atomizer is installed in porous inner tube to with feed liquid entry intercommunication. Spray drier in this scheme can prevent effectively among the dry run that the solid state material after droplet or the drying adsorbs at the inner wall and the wall phenomenon appears gluing, can increase hot -blast and mix and the contact droplet simultaneously, improves drying efficiency.
Description
Technical field
The utility model relates to a kind of spray dryer for the preparation of aluminium polychloride, belongs to drying machine technologyField.
Background technology
Aluminium polychloride is a kind of inorganic macromolecule compound, is one of most widely used flocculant at present.In aluminium polychloride is produced, need to be solid-state product through super-dry by the solution obtaining. Spraying is dry isAdopt atomizer that raw material is separated into droplet, and obtain the dry side of one of product with heated air drying dropletMethod. , in dry run, there is sticky wall problem, droplet in dry run in spray dryer of the prior artBe adsorbed on drier inwall, material solid-state after drying out adsorbs on inwall, can not take out of in time dryTower, causes product yield to decline, and when wall sticking phenomenon is serious, in order to remove sticky wall material, has to stop midwayOnly spraying is dry, and the operation cycle is extended, and production capacity declines.
Summary of the invention
The utility model provides a kind of spray dryer for the preparation of aluminium polychloride, and concrete scheme is:
For the preparation of a spray dryer for aluminium polychloride, comprise housing, warm-air pipe and sprayer, instituteThe enclosure interior of stating is provided with porous inner cylinder, and porous inner cylinder has some through holes, between porous inner cylinder and housingFormation air channel, gap; Described warm-air pipe is arranged on case top, and warm-air pipe lower end is connected with hot blast and distributesDevice, warm-air pipe is communicated with air channel by arm; Lower housing portion is provided with discharging opening; Sprayer is arranged in porousIn cylinder, and be communicated with feed liquid entrance.
Further, the through hole of described porous inner cylinder is circular port or bar hole.
Further, described porous inner cylinder is plastic cylinder.
Further, described housing is sandwich construction, is followed successively by from the inside to the outside anticorrosive coat, heat-insulation layer and notRust steel supporting layer.
Spray dryer in this programme is owing to being provided with porous inner cylinder, hot blast from arm enter porous inner cylinder withIn air channel between housing, and overflow from the through hole of porous inner cylinder, form air-flow, can effectively prevent from being driedIn process, droplet or dried solid material are adsorbed on inwall and occur wall sticking phenomenon, meanwhile, and Ke YizengThe mixing that adds hot blast and droplet with contact, improve drying efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of housing.
Detailed description of the invention
A kind of spray dryer for the preparation of aluminium polychloride as shown in Figure 1, 2, comprises housing 1, heatAirduct 2 and sprayer 3, described housing 1 inside is provided with porous inner cylinder 5, if porous inner cylinder 5 hasDry through hole 6, the formation air channel, gap 7 between porous inner cylinder 5 and housing 1; Described warm-air pipe 2 is installedAt housing 1 top, warm-air pipe 2 lower ends are connected with hot-air distributor 4, and warm-air pipe 2 is by arm 8 and windRoad 7 is communicated with; Housing 1 bottom is provided with discharging opening 10; Sprayer 3 is arranged in porous inner cylinder 5, and with materialLiquid entrance 9 is communicated with; .
The through hole 6 of the porous inner cylinder 5 described in the present embodiment is circular port or bar hole; Described porousInner core 5 is plastic cylinder; Described housing 1 is sandwich construction, is followed successively by from the inside to the outside anticorrosive coat 11, protectsTemperature layer 12 and stainless steel supporting layer 13.
Spray dryer in this programme is owing to being provided with porous inner cylinder, hot blast from arm enter porous inner cylinder withIn air channel between housing, and overflow from the through hole of porous inner cylinder, form air-flow, can effectively prevent from being driedIn process, droplet or dried solid material are adsorbed on inwall and occur wall sticking phenomenon, meanwhile, and Ke YizengThe mixing that adds hot blast and droplet with contact, improve drying efficiency.
