Abstract
The invention provides a 500 vertical type pressure spray drying tower. The 500 vertical type pressure spray drying tower comprises a tower column body, a tower cone section, a cyclone separator, an exhaust fan, an air inlet fan, an air heater and a hot air box, wherein the moisture evaporation amount is 500kg/h, the steam consumption is 1500kg/h, and materials enter three spray guns by means of a high-pressure pump through high-pressure pipelines to be atomized into mist drops at the angle ranging from 70 degrees to 80 degrees; meanwhile, heat exchange and mass exchange are fully conducted in the tower on hot air which is filtered precisely and heated through steam, and dry particles fall into the tower cone section, are vibrated by a vibrating hammer to fall into an outlet and enter the next procedure. Fine powder brought away by waste air is captured and collected through a cyclone powder capturing device ad then blown into pipes in the middle of the three spray guns through a blowing device at the bottom of cyclone so that fine powder agglomeration can be conducted, and the waste air is discharged outdoors through the exhaust fan.
Description
Technical field:
The present invention relates to a kind of drying device, especially a kind of 500 vertical pressure spray drying towers.
Background technology:
The course of work of pressure spray drying tower is to utilize high pressure that high-pressure pump produces that material is atomized into vaporific drop by atomizing mouth to spray into hothouse, with the hot-air through filtering, directly contacts and make moisture content in drop evaporation and the dry granule dry material that becomes rapidly.This equipment is applicable to the dry of various heat sensitive materials, as milk, beverage, bio-pharmaceuticals, carbohydrate powder, tealeaves and various powder based food additive, having advantages of that drying efficiency is high, can keep material active ingredient not to be destroyed, is at present above-mentioned material to be dried the preferred unit of powder process.
Summary of the invention:
In order to overcome the deficiencies in the prior art, technical problem to be solved by this invention is to provide the 500 vertical pressure spray drying towers that a kind of rational in infrastructure, rate of drying is fast, production process is simplified, drying efficiency is high.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of 500 vertical pressure spray drying towers, comprise king-post body, tower cone joint, cyclone separator, exhaust blower, air inlet fan, air heater, hot bellows, water evaporates amount: 500Kg/h, steam consumption quantity: 1500Kg/h, material enters through pressure duct the droplet that three spray guns are atomized into 70-80 degree angles by high-pressure pump, in tower, fully carry out heat exchange and matter exchange simultaneously with through secondary filter steam-heated hot blast, dry powder falls into tower tapering, by vibration hammer, shaken and fall into outlet, enter next procedure.After the fine powder whirlwind powder collector trapping of taking away with useless wind, by the blowing device of whirlwind bottom, be blown into three spray gun central tube and carry out fine powder agglomeration, useless wind is drained into outdoor by exhaust blower.

The specific embodiment:
The dry minute three phases of spraying: feed liquid atomization is drop; Droplet contacts, mixes with air and flows; Be dried; Dry products and air separation.
The atomization of first stage---feed liquid
The object of atomization is feed liquid to be separated into fine droplet, has very large surface area, and when contacting with hot-air, the moisture in droplet is vaporized rapidly and is dried to powder.The size of droplet and uniformity coefficient are very large on the quality of product and technical indicator impact; if the droplet size of ejection is very inhomogeneous; just there will be bulky grain also not reach dry requirement; and granule is dry excessively and go bad; therefore, feed liquid atomization atomizer used is spray-dired key position.
Contacting of second stage---droplet and air
Droplet contacts, mixes with air and flows is the hot mass transfer process of simultaneously carrying out, i.e. dry process.The way of contact of droplet and air, the mode that the structural shape of mixing and flow regime decision and hot air distributor, the position that atomizer is installed in tower and waste gas are discharged etc.
Phase III---dry products and air insulated
Discharging at the bottom of spray dried products employing tower, part fine powder is entrained in waste gas, and these fine powders to improve product efficiency, reduce production costs under must collecting before discharge, and the waste gas of discharge must meet the discharge standard of environmental protection, to prevent contaminated environment.The dry gas-solid separating method conventionally adopting of spraying.
